Three rows of staple cavities are positioned on a first side of the longitudinal slot and three rows of staple cavities are positioned on a second side of the longitudinal slot. Other configurations of staple cavities and staples are also possible.

钉由仓体中的钉驱动器支撑。驱动器能够在第一或非击发位置和第二或击发位置之间运动，以从钉仓射出钉。驱动器通过保持器保留在仓体中，保持器围绕仓体的底部延伸并且包括被构造成能够抓持仓体以及将保持器保持至仓体的弹性构件。驱动器能够通过滑动件在其非击发位置和击发位置之间运动。滑动件能够在与近侧端部相邻的近侧位置和与远侧端部相邻的远侧位置之间运动。滑动件包括多个斜坡表面，该斜坡表面被构造成能够朝向砧座在驱动器下方滑动以及提升驱动器，并且钉在驱动器上受到支撑。The staples are supported by staple drivers in the cartridge body. The driver is movable between a first or non-fired position and a second or fired position to fire staples from the staple cartridge. The driver is retained in the cartridge body by a retainer that extends around the bottom of the cartridge body and includes a resilient member configured to grip and retain the retainer to the cartridge body. The driver is movable between its unfired and fired positions by means of a slide. The slider is movable between a proximal position adjacent the proximal end and a distal position adjacent the distal end. The slider includes a plurality of ramp surfaces configured to slide under the driver toward the anvil and to lift the driver, and the staples are supported on the driver.

除上述以外，滑动件还可通过击发构件朝远侧运动。击发构件被构造成能够接触滑动件并朝向远侧端部推动滑动件。限定于仓体中的纵向狭槽被构造成能够接纳击发构件。砧座还包括被构造成能够接纳击发构件的狭槽。击发构件还包括接合第一钳口的第一凸轮和接合第二钳口的第二凸轮。在击发构件朝远侧推进时，第一凸轮和第二凸轮可控制钉仓的平台和砧座之间的距离或组织间隙。击发构件还包括被构造成能够切入在钉仓和砧座中间捕集的组织的刀。希望刀定位成至少部分接近斜坡表面，使得钉先于刀被射出。In addition to the above, the slider can also be moved distally by the firing member. The firing member is configured to contact the slider and urge the slider toward the distal end. A longitudinal slot defined in the cartridge body is configured to receive a firing member. The anvil also includes a slot configured to receive the firing member. The firing member also includes a first cam engaging the first jaw and a second cam engaging the second jaw. The first and second cams may control the distance or tissue clearance between the platform of the staple cartridge and the anvil as the firing member is advanced distally. The firing member also includes a knife configured to cut through tissue captured between the staple cartridge and the anvil. It is desirable for the knife to be positioned at least partially proximate the ramp surface so that the nails are fired ahead of the knife.

本文描述的某些外科缝合和切割端部执行器包括细长通道，该细长通道被构造成可移除地接收钉仓，该钉仓具有存储在钉仓中的外科钉。钉仓包括可移动地支撑在钉仓的仓主体内的射出器或驱动器，射出器或驱动器各自被构造成在其上支撑一个或多个钉。钉支撑驱动器在仓主体内布置成纵向排，其位于仓主体中限定的纵向延伸狭槽的每侧上。该狭槽被构造成可移动地容纳击发构件，该击发构件可在其上具有组织切割边缘，该组织切割边缘用于切割已经夹紧在砧座和钉仓之间的组织。当驱动器与仓主体通过滑动件接触时，驱动器被迫使在仓主体中向上，即，朝向仓主体的平台，该滑动件被构造成由击发构件纵向地驱动通过仓主体。滑动件可移动地支撑在仓中，并且包括多个成角度的或楔形的凸轮，其对应于仓主体内的钉驱动器的行。在未击发的或“新的”钉仓中，滑动件定位在每个线中最靠近钉驱动器或在钉驱动器最近侧的起始位置。在击发冲程期间，击发构件向远侧推进滑动件，以从仓主体射出钉。一旦钉仓至少部分地被击发，即从仓主体射出，击发构件就缩回到开始或未击发位置，并且滑动件保持在现在用完的钉仓的远侧。一旦击发构件已经返回到开始或未击发位置，就可将用完的钉仓从端部执行器的通道移除。Certain surgical stapling and cutting end effectors described herein include an elongated channel configured to removably receive a staple cartridge having surgical staples stored in the staple cartridge. The staple cartridge includes an ejector or driver movably supported within a cartridge body of the staple cartridge, the ejector or driver each being configured to support one or more staples thereon. The staple support drivers are arranged within the cartridge body in longitudinal rows on each side of longitudinally extending slots defined in the cartridge body. The slot is configured to movably receive a firing member, which may have a tissue cutting edge thereon for cutting tissue that has been clamped between the anvil and the staple cartridge. The driver is forced upward in the cartridge body, ie, towards the platform of the cartridge body, when the driver is in contact with the cartridge body through a slide configured to be driven longitudinally through the cartridge body by the firing member. The slider is movably supported in the cartridge and includes a plurality of angled or wedge-shaped cams that correspond to the rows of staple drivers within the cartridge body. In an unfired or "new" staple cartridge, the slider is positioned in each wire at the starting position closest to the staple driver or on the proximal-most side of the staple driver. During the firing stroke, the firing member advances the slider distally to fire the staples from the cartridge body. Once the staple cartridge is at least partially fired, ie, fired from the cartridge body, the firing member is retracted to the start or unfired position, and the slider remains distal to the now spent staple cartridge. Once the firing member has returned to the starting or unfired position, the spent staple cartridge can be removed from the channel of the end effector.

除上述之外，图1中示出了外科器械系统10。外科器械系统10包括柄部14和轴组件200，轴组件200可移除地可附接到柄部14。轴组件200包括端部执行器300，端部执行器300包括仓通道302和能够相对于仓通道302移动的砧座306。钉仓304可移除地定位在仓通道302中。In addition to the above,surgical instrument system 10 is shown in FIG. 1 .Surgical instrument system 10 includeshandle 14 andshaft assembly 200 that is removably attachable to handle 14 . Theshaft assembly 200 includes anend effector 300 that includes acartridge channel 302 and ananvil 306 that is movable relative to thecartridge channel 302 . Astaple cartridge 304 is removably positioned in thecartridge channel 302 .

此类切割和缝合端部执行器安装到细长轴组件的远侧端部，细长轴组件可操作地支撑各种驱动轴和部件，该驱动轴和部件被构造成将各种控制运动施加到端部执行器。在各种情况下，轴组件可包括关节运动接头，或者当关节运动动作被施加到端部执行器时，可以其它方式被构造成便于端部执行器相对于细长轴的一部分进行关节运动。轴组件联接到支撑各种驱动系统的壳体，所述系统在细长轴组件中可操作地与各种组件对接。在某些布置中，壳体可包括手持壳体或柄部。在其它布置中，壳体可包括机器人或自动外科系统的一部分。壳体的各种驱动系统可被构造成将轴向驱动运动、旋转驱动运动和/或轴向驱动运动和旋转驱动运动的组合施加到细长轴组件。在手持式布置中，轴向运动可由一个或多个手动致动的手动曲柄产生和/或由一个或多个电动马达产生。机器人系统可采用电动马达和/或其它自动驱动布置，其被构造成产生并向细长轴组件施加必要的控制运动，并且在一些情况下，最终向端部执行器中的击发构件施加必要的控制运动。Such cutting and stapling end effectors are mounted to the distal end of an elongated shaft assembly operatively supporting various drive shafts and components configured to impart various control motions to the end effector. In various cases, the shaft assembly may include an articulation joint, or may be otherwise configured to facilitate articulation of the end effector relative to a portion of the elongated shaft when an articulation action is applied to the end effector. The shaft assembly is coupled to a housing that supports various drive systems that operably interface with the various components in the elongated shaft assembly. In some arrangements, the housing may include a handheld housing or handle. In other arrangements, the housing may include part of a robotic or automated surgical system. The various drive systems of the housing may be configured to impart axial drive motion, rotational drive motion, and/or a combination of axial and rotational drive motion to the elongated shaft assembly. In a hand-held arrangement, the axial movement may be produced by one or more manually actuated hand cranks and/or by one or more electric motors. The robotic system may employ electric motors and/or other automated drive arrangements configured to generate and apply the necessary control motion to the elongated shaft assembly and, in some cases, ultimately to the firing member in the end effector. Control movement.

对于需要旋转控制运动的外科端部执行器，细长轴组件可包括“近侧”旋转驱动轴部分，其由对应的马达或支撑在壳体中的其它旋转运动源旋转。近侧旋转驱动轴被构造成将旋转控制运动施加到端部执行器驱动轴，该端部执行器驱动轴支撑在端部执行器中。在此类布置中，击发构件与端部执行器驱动轴对接，使得击发构件可被纵向推进通过端部执行器，然后返回到未击发位置。For surgical end effectors requiring rotationally controlled motion, the elongated shaft assembly may include a "proximal" rotational drive shaft portion that is rotated by a corresponding motor or other source of rotational motion supported in the housing. The proximal rotational drive shaft is configured to apply rotational control motion to an end effector drive shaft supported in the end effector. In such arrangements, the firing member interfaces with the end effector drive shaft such that the firing member can be advanced longitudinally through the end effector and then returned to the unfired position.

当使用被构造成切割和缝合组织的外科器械时，应采取措施以确保在致动外科器械的击发驱动系统之前已将未用完的外科钉仓正确地安装在外科器械的端部执行器中。例如，如果临床医生无意中致动了击发驱动系统的组织切割构件而没有首先在端部执行器中安装未用完的钉仓，则组织切割构件可以在不缝合组织的情况下切断组织。如果临床医生无意中将部分用完的钉仓安装到端部执行器中，也会出现类似的问题。当在先前手术中或手术的先前步骤中使用钉仓时，可以产生部分用完的钉仓，然后在钉中的全部从其中射出之前从端部执行器移除。如果要在外科器械中重复使用此种部分用完的仓，则组织切割构件可在组织中产生比施加到组织的钉线更长的切口。因此，当使用被构造成切割和缝合组织的外科端部执行器时，期望外科端部执行器被构造成防止组织切割构件的致动，除非未用完的“新的”钉仓已正确安装在端部执行器中。When using a surgical instrument configured to cut and staple tissue, steps should be taken to ensure that an unused surgical staple cartridge has been properly installed in the surgical instrument's end effector prior to actuating the surgical instrument's firing drive system . For example, if a clinician inadvertently actuates the tissue-cutting member of the firing drive system without first installing an unused cartridge in the end effector, the tissue-cutting member may sever tissue without stapling the tissue. A similar problem can arise if a clinician inadvertently installs a partially used cartridge into an end effector. When a staple cartridge is used in a previous procedure or in a previous step of a procedure, a partially used staple cartridge can be created and then removed from the end effector before all of the staples are ejected therefrom. If such a partially used cartridge is to be reused in a surgical instrument, the tissue cutting member can create a longer incision in the tissue than the staple line applied to the tissue. Therefore, when using a surgical end effector configured to cut and staple tissue, it is desirable that the surgical end effector be configured to prevent actuation of the tissue cutting member unless an unused "new" staple cartridge has been properly installed in the end effector.

图2和图3示出了可解决此类问题的外科切割和缝合端部执行器20000的部分。如在图2和图3中可以看到的，端部执行器20000包括旋转端部执行器驱动轴20010。虽然未示出，但是旋转端部执行器驱动轴20010可旋转地支撑在细长通道内，该细长通道被构造成在细长通道中可移除地支撑外科钉仓。旋转端部执行器驱动轴20010被构造成从近侧旋转驱动轴接收旋转驱动运动，该近侧旋转驱动轴附接到通道或以其它方式可操作地与旋转端部执行器驱动轴20010对接。旋转控制运动可通过对应的驱动布置施加到近侧旋转驱动轴，该驱动布置可包括由机器人控制系统或其它(一个或多个)旋转控制运动源手动致动或控制的一个或多个马达。在另选布置中，可手动产生旋转控制运动。仍然参考图2和图3，外科端部执行器20000包括击发组件20020，该击发组件20020被构造用于在通道内纵向行进。在所示实施方案中，击发组件20020包括上部击发主体20022，该上部击发主体20022具有远侧击发耳状物20024和近侧击发耳状物20026。在远侧击发耳状物20024中具有无螺纹孔(未示出)，该无螺纹孔被构造成接收穿过其中的旋转端部执行器驱动轴20010。近侧击发耳状物20026与远侧击发耳状物20024间隔开，以在近侧击发耳状物和远侧击发耳状物之间限定螺母腔体20028。近侧击发耳状物20026具有穿过其中的无螺纹孔20027，该无螺纹孔20027被构造成接收穿过其中的旋转端部执行器驱动轴20010。2 and 3 illustrate portions of a surgical cutting and staplingend effector 20000 that may address such issues. As can be seen in FIGS. 2 and 3 , theend effector 20000 includes a rotating endeffector drive shaft 20010 . Although not shown, a rotating endeffector drive shaft 20010 is rotatably supported within an elongated channel configured to removably support a surgical staple cartridge within the elongated channel. The rotary endeffector drive shaft 20010 is configured to receive rotational drive motion from a proximal rotary drive shaft that is attached to or otherwise operably interfaced with the rotary endeffector drive shaft 20010. Rotational control motion may be applied to the proximal rotational drive shaft by a corresponding drive arrangement, which may include one or more motors manually actuated or controlled by a robotic control system or other source(s) of rotational control motion. In an alternative arrangement, the rotational control movement may be generated manually. Still referring to Figures 2 and 3, thesurgical end effector 20000 includes a firingassembly 20020 configured to travel longitudinally within the channel. In the illustrated embodiment, the firingassembly 20020 includes anupper firing body 20022 having adistal firing ear 20024 and aproximal firing ear 20026. In thedistal firing ear 20024 is an unthreaded bore (not shown) configured to receive the rotating endeffector drive shaft 20010 therethrough. Theproximal firing ear 20026 is spaced apart from thedistal firing ear 20024 to define anut cavity 20028 between the proximal firing ear and the distal firing ear. Theproximal firing ear 20026 has an unthreadedbore 20027 therethrough configured to receive the rotating endeffector drive shaft 20010 therethrough.

如在图2和图3中可以看到的，旋转端部执行器驱动轴20010带有螺纹。击发组件20020包括行进螺母20030，该螺母20030通过螺纹轴颈连接在旋转端部执行器驱动轴20010上并且位于远侧击发耳状物20026和近侧击发耳状物20027之间的螺母腔体20028中。行进螺母20040能够在螺母腔体20028内在第一位置(图2)和第二位置(图3)之间移动。行进螺母20040包括上凹口部分20042，上凹口部分20042具有从其突出的向远侧延伸的保持器突片20044。当行进螺母20040处于第一位置时，带凹口的上部部分20042与击发组件20020的上部击发主体20022垂直对准。如可以在图2和图3中进一步看到的，远侧击发耳状物20024可包括一对侧向突出的远侧翼片20025(图中仅可以看到一个)，并且近侧击发耳状物20026可包括一对侧向突出的近侧翼片20027。同样地，行进螺母20040可包括一对螺母翼片20046，当行进螺母20040处于第一位置时，螺母翼片被构造成与远侧翼片20025和近侧翼片20027对准。参见图2。当处于该对准位置时，翼片20025、20027和20046自由地在设置在钉仓主体中的通道内穿过。同样在所示的布置中，击发组件20020的上部主体部分20022包括一对侧向突出的上部翼片20030，当击发组件在远侧驱动通过端部执行器时，上部翼片被构造成可滑动地接收在砧座中的对应通道中或以其它方式可滑动地接合砧座。因此，翼片20025、20027、20046和上部翼片20030用于在击发过程期间将砧座保持在距钉仓期望的距离处。击发组件20020还包括组织切割表面或组织切割刀片20032，用于切割已经夹紧在砧座和钉仓之间的组织。As can be seen in Figures 2 and 3, the rotary endeffector drive shaft 20010 is threaded. The firingassembly 20020 includes atravel nut 20030 that is journaled on the rotating endeffector drive shaft 20010 by a threaded journal and located in anut cavity 20028 between thedistal firing ear 20026 and theproximal firing ear 20027 middle. Thetravel nut 20040 is movable within thenut cavity 20028 between a first position (FIG. 2) and a second position (FIG. 3). Thetravel nut 20040 includes anupper notch portion 20042 having a distally extendingretainer tab 20044 protruding therefrom. The notchedupper portion 20042 is vertically aligned with theupper firing body 20022 of the firingassembly 20020 when thetravel nut 20040 is in the first position. As can be further seen in Figures 2 and 3, thedistal firing ears 20024 may include a pair of laterally projecting distal tabs 20025 (only one can be seen in the Figures), and theproximal firing ears 20026 can include a pair of laterally projectingproximal flaps 20027. Likewise, thetravel nut 20040 can include a pair ofnut tabs 20046 that are configured to align with thedistal tabs 20025 and theproximal tabs 20027 when thetravel nut 20040 is in the first position. See Figure 2. When in this aligned position, thetabs 20025, 20027 and 20046 are free to pass within the channels provided in the cartridge body. Also in the arrangement shown, theupper body portion 20022 of the firingassembly 20020 includes a pair of laterally projectingupper tabs 20030 that are configured to slide when the firing assembly is driven distally through the end effector are received in corresponding passages in the anvil or otherwise slidably engage the anvil. Thus, thetabs 20025, 20027, 20046 and theupper tab 20030 are used to maintain the anvil at a desired distance from the staple cartridge during the firing process. The firingassembly 20020 also includes a tissue cutting surface ortissue cutting blade 20032 for cutting tissue that has been clamped between the anvil and the staple cartridge.

外科端部执行器20000的通道被构造成在该通道中能够可操作地且可移除地支撑外科钉仓，该外科钉仓包括滑动件20050。滑动件20050能够从位于钉仓近侧端部中的起始位置移动到钉仓内的结束位置。滑动件20050包括中央滑动件主体20052，所述中央滑动件主体具有形成在中央滑动件主体中的一堆凸轮楔形件20054。在所示的示例中，滑动件20050包括四个凸轮楔形件20054，其中两个凸轮楔形件20054位于中央滑动件主体20052的每侧上。每个凸轮楔形件20054将对应于位于仓主体中的一行钉支撑驱动器。当滑动件20050向远侧驱动通过仓主体时，凸轮楔形件20054在仓主体内向上依次驱动对应行中的钉驱动器，以从而将钉射出成与砧座的下侧的形成接触。The channel of thesurgical end effector 20000 is configured to operably and removably support a surgical staple cartridge including aslider 20050 therein.Slider 20050 is movable from a starting position in the proximal end of the staple cartridge to an ending position within the staple cartridge.Slider 20050 includes acenter slider body 20052 with a stack ofcam wedges 20054 formed in the center slider body. In the example shown, theslider 20050 includes fourcam wedges 20054 , with twocam wedges 20054 on each side of thecentral slider body 20052 . Eachcam wedge 20054 will correspond to a row of staple support drivers located in the cartridge body. As thesled 20050 is driven distally through the cartridge body, thecam wedges 20054 sequentially drive the staple drivers in corresponding rows up within the cartridge body to thereby fire the staples into contact with the underside of the anvil.

在所示的示例中，滑动件20050包括形成在中央滑动件主体20052中的保持腔体20056，当行进螺母处于第一位置并且滑动件20050处于起始(预击发)位置时，中央滑动件主体被构造成保持地接合行进螺母20040上的向远侧延伸的保持器凸片20044。参见图2。在某些布置中，一个或多个偏压构件20060可设置在击发组件20020中，以将行进螺母20040偏压到第一位置。例如，扭转弹簧可被支撑在近侧击发耳状物20024和远侧击发耳状物20026中的一个或二者中，以在螺纹端部执行器驱动轴20020未致动时将行进螺母20040偏压到第一位置(方向D1)。然而，当螺纹端部执行器驱动轴20020在击发方向(D2)上旋转时，旋转驱动轴20020克服偏压构件20060的偏压并且将行进螺母20030移动到图3中所示的第二位置。当行进螺母20030处于第二位置时，保持突片20044与仓主体中的狭槽不对准，该狭槽可滑动地容纳中央滑动件主体20052中并且螺母翼片20046与仓主体中的通道不对准。因此，旋转端部执行器驱动杆20010的进一步旋转由于突片20044和翼片20046与仓主体的对应部分的这种未对准而将不会向远侧驱动击发组件20020。但是，如果仓未用完(从未被击发)，则仓20050将处于起始位置。当仓正确地坐置在端部执行器通道中时，保持器突片20044将被接收在滑动件20050中的保持腔体20056中，当旋转端部执行器驱动轴20010在击发方向上旋转时，该保持腔体2004将行进螺母20030保持在第一位置。因此，当未用完的仓未正确地坐置在通道中时，此种布置将防止临床医生无意中推进击发组件20020(和组织切割表面20044)。因此，当未用完的仓未正确地坐置在通道中时，此种布置将防止临床医生无意中推进击发组件20020(和组织切割表面20044)。如果未用完的仓存在于通道中，但尚未正确地坐置在通道中，使得保持突片被接收在滑动件中的保持腔体内，则临床医生将不能推进击发组件。In the example shown, theslider 20050 includes aretention cavity 20056 formed in thecenter slider body 20052, which is formed when the travel nut is in the first position and theslider 20050 is in the starting (pre-fired) position. A distally extendingretainer tab 20044 on thetravel nut 20040 is configured to be retained. See Figure 2. In certain arrangements, one ormore biasing members 20060 may be provided in the firingassembly 20020 to bias thetravel nut 20040 to the first position. For example, a torsion spring can be supported in one or both of the proximal firing lugs 20024 and the distal firing lugs 20026 to bias thetravel nut 20040 when the threaded endeffector drive shaft 20020 is not actuated Press to the first position (direction D1). However, when the threaded endeffector drive shaft 20020 is rotated in the firing direction (D2), therotational drive shaft 20020 overcomes the bias of the biasingmember 20060 and moves thetravel nut 20030 to the second position shown in FIG. When thetravel nut 20030 is in the second position, theretention tabs 20044 are misaligned with the slots in the cartridge body slidably received in thecenter slider body 20052 and thenut tabs 20046 are misaligned with the channels in the cartridge body . Thus, further rotation of the rotary endeffector drive rod 20010 will not drive the firingassembly 20020 distally due to this misalignment of thetabs 20044 andtabs 20046 with corresponding portions of the cartridge body. However, if the bin is not used up (never fired), then thebin 20050 will be in the starting position. When the cartridge is properly seated in the end effector channel, theretainer tab 20044 will be received in the retainingcavity 20056 in theslide 20050 when the rotary endeffector drive shaft 20010 is rotated in the firing direction , the retaining cavity 2004 retains thetravel nut 20030 in the first position. Thus, this arrangement will prevent the clinician from inadvertently advancing the firing assembly 20020 (and tissue cutting surface 20044) when the unused cartridge is not properly seated in the channel. Thus, this arrangement will prevent the clinician from inadvertently advancing the firing assembly 20020 (and tissue cutting surface 20044) when the unused cartridge is not properly seated in the channel. If an unused cartridge is present in the channel, but has not been properly seated in the channel such that the retention tab is received within the retention cavity in the slider, the clinician will not be able to advance the firing assembly.

下面转向图4至图6，示出了另一个外科切割和缝合端部执行器20100的部分。端部执行器20100包括通道20110，该通道20110被构造成在通道中可移除地接收外科钉仓20200。在至少一个实施方案中，端部执行器20100包括旋转端部执行器驱动轴20120，其能够在第一“锁定”位置和第二“驱动”位置之间选择性地移动或偏转。旋转端部执行器驱动轴20120被构造成从近侧旋转驱动轴(未示出)接收旋转驱动运动。旋转控制运动可通过对应的驱动布置施加到近侧旋转驱动轴，该驱动布置可包括由机器人控制系统手动致动或控制的一个或多个马达。在另选布置中，可手动产生旋转控制运动。旋转端部执行器驱动轴20120可通过对应的旋转轴承布置或支架可旋转地支撑在其近侧端部和远侧端部上，该旋转轴承布置或支架便于旋转端部执行器驱动轴20120的操作旋转，但使得旋转端部执行器驱动轴的一部分能够在第一位置和第二位置之间偏转，同时保持与近侧旋转驱动轴或其它旋转运动源的旋转操作接合。Turning now to Figures 4-6, portions of another surgical cutting and staplingend effector 20100 are shown. Theend effector 20100 includes achannel 20110 configured to removably receive a surgicalstaple cartridge 20200 therein. In at least one embodiment, theend effector 20100 includes a rotating endeffector drive shaft 20120 that can be selectively moved or deflected between a first "locked" position and a second "driven" position. The rotary endeffector drive shaft 20120 is configured to receive rotational drive motion from a proximal rotational drive shaft (not shown). The rotational control motion may be applied to the proximal rotational drive shaft by a corresponding drive arrangement, which may include one or more motors manually actuated or controlled by a robotic control system. In an alternative arrangement, the rotational control movement may be generated manually. The rotating endeffector drive shaft 20120 may be rotatably supported on its proximal and distal ends by corresponding rotating bearing arrangements or brackets that facilitate rotation of the rotating endeffector drive shaft 20120. The operation rotates but enables a portion of the rotary end effector drive shaft to deflect between a first position and a second position while maintaining rotational operative engagement with the proximal rotary drive shaft or other source of rotational motion.

如图4至图8中可以看到的，外科端部执行器20100包括击发组件20130，该击发组件20130被构造用于在通道20110内纵向行进。在所示实施方案中，击发组件20130包括击发主体20132，击发主体20132螺纹地轴颈连接在旋转端部执行器驱动轴20120上。击发主体20132包括一对侧向突出的翼片20134，其构造成在通道20110中的通路20112内穿过。通路20112可由两个向内延伸的间隔开的通道突片20114(在图7和图8中仅可以看到一个突片)限定，在所述通道突片之间具有狭槽20116以容纳旋转端部执行器驱动轴20120以及其间的击发主体20132的通路。参见图7和图8。同样在所示的布置中，击发组件20130的上部主体部分20136包括一对侧向突出的上部翼片20138，当击发组件20130被向远侧驱动穿过端部执行器20100时，上部翼片被构造成可滑动地接收在砧座20150中的对应通道20152中。因此，翼片20134和20138用于在击发过程期间将砧座20150保持在距钉仓20200期望的距离处。击发组件20130还包括组织切割表面或组织切割刀片20139，其被构造成切割已经夹紧在砧座和钉仓之间的组织。As can be seen in FIGS. 4-8 , thesurgical end effector 20100 includes a firingassembly 20130 configured to travel longitudinally within thechannel 20110 . In the illustrated embodiment, the firingassembly 20130 includes afiring body 20132 that is threadedly journaled on the rotating endeffector drive shaft 20120. The firingbody 20132 includes a pair of laterally projectingfins 20134 configured to pass within thepassageway 20112 in thechannel 20110. Thepassageway 20112 may be defined by two inwardly extending spaced apart channel tabs 20114 (only one tab can be seen in Figures 7 and 8) with aslot 20116 therebetween to accommodate the swivel end Part of theactuator drive shaft 20120 and the passage of thefiring body 20132 therebetween. See Figures 7 and 8. Also in the arrangement shown, theupper body portion 20136 of the firingassembly 20130 includes a pair of laterally projectingupper tabs 20138 that are driven by the firingassembly 20130 distally through theend effector 20100 are configured to be slidably received in correspondingchannels 20152 in theanvil 20150. Thus, thetabs 20134 and 20138 are used to maintain theanvil 20150 at a desired distance from thestaple cartridge 20200 during the firing process. The firingassembly 20130 also includes a tissue cutting surface ortissue cutting blade 20139 configured to cut tissue that has been clamped between the anvil and the staple cartridge.

图4示出了将未用完的钉仓20200安装到外科端部执行器20100中。如图4中可以看到的，未用完的钉仓20200包括位于起始位置的滑动件20210。滑动件20210能够从位于钉仓20200近侧端部中的起始位置移动到仓20200内的结束位置。如图8中可以看到的，滑动件20210包括中央滑动件主体20212，中央滑动件主体具有形成在中央滑动件主体中的一堆凸轮楔形件20214。在所示的示例中，滑动件20210包括四个凸轮楔形件20214，其中两个凸轮楔形件20214位于中央滑动件主体20212的每侧上。每个凸轮楔形件20214对应于支撑在仓20200中的一行钉支撑驱动器。当滑动件20210向远侧驱动通过仓20200时，凸轮楔形件20214在仓20200内向上依次驱动对应行中的钉驱动器，以从而将钉驱动成与砧座2015的下侧的形成接触。在将未用完的钉仓20200坐置在通道20110中之前，旋转驱动轴20120位于第一位置或向上位置(由箭头“U”表示)。图7示出了在将钉仓安装在端部执行器内之前旋转驱动轴20120和击发组件20130处于锁定位置的位置。如图7中可以看到的，翼片20134与通道20110的通道突片20144对准，使得如果临床医生努力致动旋转驱动轴20120以向远侧驱动击发组件通过通道20110，则由于翼片20134和通道突片20114之间的接触，将防止击发组件20130向远侧移动。旋转驱动轴20120以及击发组件20130可向下偏转的距离在图7中表示为距离Df。FIG. 4 shows the installation of anunused staple cartridge 20200 into thesurgical end effector 20100. As can be seen in Figure 4, theunused staple cartridge 20200 includes aslider 20210 in a starting position. Theslider 20210 is movable from a starting position in the proximal end of thestaple cartridge 20200 to an ending position within thecartridge 20200. As can be seen in Figure 8, theslider 20210 includes acentral slider body 20212 having a stack ofcam wedges 20214 formed in the central slider body. In the example shown, theslider 20210 includes fourcam wedges 20214 , with twocam wedges 20214 on each side of thecentral slider body 20212 . Eachcam wedge 20214 corresponds to a row of staple support drivers supported in thecartridge 20200. As thesled 20210 is driven distally through thecartridge 20200 , thecam wedges 20214 sequentially drive the staple drivers in corresponding rows upward within thecartridge 20200 to thereby drive the staples into contact with the underside of the anvil 2015 . Before seating theunused staple cartridge 20200 in thechannel 20110, therotary drive shaft 20120 is in the first or up position (indicated by arrow "U"). Figure 7 shows therotational drive shaft 20120 and firingassembly 20130 in a locked position prior to installation of the staple cartridge within the end effector. As can be seen in FIG. 7 , thetabs 20134 are aligned with the channel tabs 20144 of thechannel 20110 such that if the clinician attempts to actuate therotary drive shaft 20120 to drive the firing assembly distally through thechannel 20110 , due to thetabs 20134 Contact with thechannel tab 20114 will prevent distal movement of the firingassembly 20130. The distance by which therotary drive shaft 20120 and the firingassembly 20130 can be deflected downward is represented in FIG. 7 as distance Df.

在所示的示例中，击发组件接合凹口20216设置在滑动件主体20212中，其构造成接合击发组件20130的上主体部分20136中的对应接合凹口20137。当滑动件20210的击发组件接合凹口20216最初接合击发组件20130的上部主体部分20136中的接合凹口20137，滑动件20120将击发组件20130和端部执行器旋转驱动轴20120向下偏压或偏转到通道20110中(由图8中的箭头“D”表示)。此种运动使击发组件20130的翼片20134与通道20110中的通路20112对准。外科钉仓20220可被构造成咬合到通道20100中并以正确安装的取向保持在通道中。图5和图8示出了处于“驱动位置”或“第二位置”的旋转驱动轴20120，其中击发组件20130与通道20110垂直对准，以便准许当旋转驱动轴20120在击发方向上旋转时击发组件20130向远侧驱动通过钉仓20200。In the example shown, firing assembly engagement recesses 20216 are provided in theslider body 20212 that are configured to engage corresponding engagement recesses 20137 in theupper body portion 20136 of the firingassembly 20130 . When the firingassembly engagement recess 20216 of theslider 20210 initially engages theengagement recess 20137 in theupper body portion 20136 of the firingassembly 20130, theslider 20120 biases or deflects the firingassembly 20130 and the end effectorrotational drive shaft 20120 downwardly into channel 20110 (indicated by arrow "D" in Figure 8). This movement aligns thetabs 20134 of the firingassembly 20130 with thepassageways 20112 in thechannel 20110. The surgical staple cartridge 20220 can be configured to snap into thechannel 20100 and remain in the channel in a properly installed orientation. Figures 5 and 8 show therotary drive shaft 20120 in a "drive position" or "second position" with the firingassembly 20130 vertically aligned with thechannel 20110 to permit firing when therotary drive shaft 20120 is rotated in thefiring direction Assembly 20130 is driven distally throughcartridge 20200.

图6示出了用完的或部分用完的钉仓20200’安装到外科端部执行器20100中。如在图6中可以看到的，滑动件20210已经从钉仓20200’内的起始位置向远侧移动。因此，当钉仓20200’正确地安装在通道20110内时，滑动件20210，更具体地，滑动件20210中的击发组件接合凹口20126与击发组件20130中的接合凹口20137脱离接合。因此，击发组件20130保持在第一或锁定位置。因此，如果临床医生无意中致动旋转端部执行器驱动轴20120，则击发组件20130将不会被向远侧推进到仓20200’中。FIG. 6 shows a spent or partially spent staple cartridge 20200' installed into thesurgical end effector 20100. As can be seen in Figure 6, theslider 20210 has moved distally from the starting position within the staple cartridge 20200'. Thus, when the cartridge 20200' is properly installed within thechannel 20110, theslider 20210, and more specifically, the firing assembly engagement notch 20126 in theslider 20210, disengages theengagement notch 20137 in the firingassembly 20130. Thus, the firingassembly 20130 remains in the first or locked position. Thus, if the clinician inadvertently actuates the rotating endeffector drive shaft 20120, the firingassembly 20130 will not be advanced distally into the cartridge 20200'.

图9至图14示出了另一个可锁定击发组件20300的部分，其被防止向远侧推进，除非未用完的外科钉仓已正确地坐置在端部执行器通道20400内。图9示出了击发组件20300的螺纹螺母部分20302，其以本文所述的方式通过螺纹轴颈连接在旋转端部执行器驱动轴上。为清楚起见，在图9至图14中省略了旋转端部执行器驱动轴。在所示实施方案中，锁定耳状物20304和致动器耳状物20306从螺纹螺母部分20302侧向突出。尽管未示出，但击发组件20300包括具有组织切割边缘的上部击发主体，该组织切割边缘可类似于本文所公开的那些。图10至图14示出了与通道20400连接的螺纹螺母部分20302。应当理解，通道20400被构造成能够可操作地且可移除地将外科钉仓支撑在通道中。首先转到图10，通道20400包括居中设置的纵向狭槽20402，其被构造成能够可操作地支撑旋转端部执行器驱动轴以及准许螺纹螺母20302纵向行进通过通道20400。另外，第一纵向突出部分20404和第二纵向突出部分20406设置在纵向狭槽20402的每侧上。突出部分20404、20406用于限定纵向通道20408，当击发组件20300向远侧击发通过通道20400时，纵向通道20408准许突出部分20304和20306在通道中通过。另外，通道20400包括纵向腔体20410，以用于在纵向腔体中接收仓主体。应当理解的是，仓主体可被构造成咬合地且可移除地保持在腔体20410内。FIGS. 9-14 illustrate a portion of anotherlockable firing assembly 20300 that is prevented from advancing distally unless an unused surgical staple cartridge has been properly seated within theend effector channel 20400. Figure 9 shows the threadednut portion 20302 of the firingassembly 20300, which is journalled on the rotating end effector drive shaft in a manner described herein. For clarity, the rotating end effector drive shaft is omitted in FIGS. 9-14 . In the embodiment shown, the locking lugs 20304 and actuator lugs 20306 project laterally from the threadednut portion 20302. Although not shown, the firingassembly 20300 includes an upper firing body having a tissue cutting edge, which may be similar to those disclosed herein. 10-14 show the threadednut portion 20302 connected to thechannel 20400. It should be appreciated that thechannel 20400 is configured to operably and removably support a surgical staple cartridge within the channel. Turning first to FIG. 10 , thepassageway 20400 includes a centrally disposedlongitudinal slot 20402 configured to operably support a rotating end effector drive shaft and permit longitudinal travel of a threadednut 20302 through thepassageway 20400 . Additionally, a firstlongitudinal protrusion 20404 and a secondlongitudinal protrusion 20406 are provided on each side of thelongitudinal slot 20402. Theprojections 20404, 20406 serve to define alongitudinal channel 20408 that permits theprojections 20304 and 20306 to pass therethrough when the firingassembly 20300 is fired distally through thechannel 20400. Additionally, thechannel 20400 includes alongitudinal cavity 20410 for receiving the cartridge body in the longitudinal cavity. It should be appreciated that the cartridge body may be configured to snap and removably be retained withincavity 20410.

在所示实施方案中，锁定凹口20412设置在突出部分20404中。当击发组件20300在击发之前处于第一位置或开始位置时，锁定凹口20412的尺寸被设计成在锁定凹口中接收锁定耳状物20304的至少一部分。锁定弹簧或偏压构件20414设置在突出部分20406上并且被构造成在锁定方向“L”上接合并偏压致动器耳状物20306。致动器耳状物20306的此种旋转促使锁定耳状物20304进入锁定凹口20412。当处于该位置时，当旋转端部执行器驱动轴在击发方向上旋转时，击发组件20300不能向远侧推进。In the embodiment shown, the lockingnotch 20412 is provided in the protrudingportion 20404. When the firingassembly 20300 is in the first or starting position prior to firing, thelocking recess 20412 is sized to receive at least a portion of the lockinglug 20304 in the locking recess. A locking spring or biasingmember 20414 is provided on the protrudingportion 20406 and is configured to engage and bias theactuator ear 20306 in the locking direction "L". This rotation of theactuator ear 20306 urges the lockingear 20304 into thelocking recess 20412. When in this position, the firingassembly 20300 cannot be advanced distally when the rotary end effector drive shaft is rotated in the firing direction.

图12示出了当击发组件已经移动到第二或解锁位置时击发组件20300的螺纹螺母部分20302的位置。图13示出了当外科钉仓最初被引入通道20400时发生的情况。在图13和图14中，为清楚起见省略了仓主体。然而，应当理解，外科钉仓包括滑动件20500。滑动件20500能够从位于钉仓近侧端部中的起始位置移动到钉仓内的结束位置。如图13和图14中可以看到的，滑动件20500包括中央滑动件主体20502，中央滑动件主体具有形成在中央滑动件主体中的一堆凸轮楔形件20504。在所示的示例中，滑动件20500包括四个凸轮楔形件20504，其中两个凸轮楔形件20504位于中央滑动件主体20502的每侧上。每个凸轮楔形件20054对应于位于仓20500中的一行钉支撑驱动器。当滑动件20500向远侧驱动通过仓时，凸轮楔形件20504在仓内向上依次驱动对应行中的钉驱动器，以从而将钉射出成与砧座的下侧的形成接触。Figure 12 shows the position of the threadednut portion 20302 of the firingassembly 20300 when the firing assembly has been moved to the second or unlocked position. 13 shows what happens when a surgical staple cartridge is initially introduced intochannel 20400. In Figures 13 and 14, the cartridge body is omitted for clarity. It should be understood, however, that the surgical staple cartridge includes aslider 20500.Slider 20500 is movable from a starting position in the proximal end of the staple cartridge to an ending position within the staple cartridge. As can be seen in Figures 13 and 14, theslider 20500 includes acenter slider body 20502 having a stack ofcam wedges 20504 formed in the center slider body. In the example shown, theslider 20500 includes fourcam wedges 20504 , with twocam wedges 20504 on each side of thecentral slider body 20502 . Eachcam wedge 20054 corresponds to a row of staple support drivers located in thecartridge 20500. As theslider 20500 is driven distally through the cartridge, thecam wedges 20504 sequentially drive the staple drivers in the corresponding row up within the cartridge to thereby fire the staples into contact with the underside of the anvil.

仍然参考图13，当仓正确地安装在通道20400内并且滑动件处于起始位置时，滑动件20500被构造成接触致动器耳状物20306。在所示实施方案中，例如，向下延伸的致动器构件20506形成在滑动件20500上或以其它方式附接到滑动件20500。当仓安装在通道20400中时，滑动件20500上的致动器构件20506接触致动器耳状物20306并将击发组件在解锁方向“UL”(图13)上偏压到图14中所示的位置。如图14中可以看到的，锁定耳状物20304脱出锁定凹口20412，并且击发组件20300现在可以被纵向推进通过通道和钉仓。因此，此种布置将防止临床医生无意中推进击发组件，除非具有处于起始位置的滑动件的仓已经正确地安装在通道中。如在此上下文中使用的，术语“正确安装”意味着钉仓已经以预期的方式保持地坐置在通道中，以便准许滑动件和其其它部分以本文所述的方式与击发组件相互作用。Still referring to FIG. 13 , theslider 20500 is configured to contact theactuator ears 20306 when the cartridge is properly installed within thechannel 20400 and the slider is in the home position. In the illustrated embodiment, for example, a downwardly extendingactuator member 20506 is formed on or otherwise attached to theslider 20500. When the cartridge is installed in thechannel 20400, theactuator member 20506 on theslider 20500 contacts theactuator ears 20306 and biases the firing assembly in the unlock direction "UL" (FIG. 13) as shown in FIG. 14 s position. As can be seen in Figure 14, the locking lugs 20304 disengage the lockingnotches 20412, and the firingassembly 20300 can now be advanced longitudinally through the channel and cartridge. Thus, this arrangement will prevent the clinician from inadvertently advancing the firing assembly unless the cartridge with the slider in the starting position has been properly installed in the channel. As used in this context, the term "correctly installed" means that the staple cartridge has remained seated in the channel in the intended manner so as to permit the slider and other portions thereof to interact with the firing assembly in the manner described herein.

图15至图17示出了端部执行器20500的部分，该端部执行器被构造为切割和缝合组织。端部执行器20500包括细长通道20510，该细长通道20510被构造成在细长通道中能够可操作地支撑外科钉仓20600。端部执行器包括砧座组件20700，其可操作地支撑砧座同心驱动构件20710，用于可操作地将击发构件20720驱动通过端部执行器20500。砧座同心驱动构件20710可例如居中地设置在砧座框架20712内并且基本上延伸其长度。在所示实施方案中，砧座同心驱动构件20710包括砧座驱动轴，该砧座驱动轴包括远侧轴承耳状物20714和近侧轴承耳状物20716。远侧轴承耳状物20714可旋转地容纳在远侧轴承壳体20718中，该远侧轴承壳体20718支撑在砧座框架20712中的轴承凹坑中。近侧轴承耳状物20716通过浮接轴承壳体20720可旋转地支撑在砧座组件20700中，该浮接轴承壳体20720可移动地支撑在形成于近侧砧座部分20724中的轴承凹坑20722中。参见图16。近侧轴承壳体布置和远侧轴承壳体布置可用于防止或至少最小化砧座驱动轴20710上的压缩力的发生，否则可能导致砧座驱动轴20710在高力条件下屈曲。砧座驱动轴20710还包括从动击发齿轮20726、近侧螺纹或螺旋区段20728和远侧螺纹或螺旋区段20730。在所示的布置中，近侧螺纹区段20728具有第一长度，并且远侧螺纹区段20730具有大于第一长度的远侧长度。在所示的布置中，远侧螺纹区段20730的节距大于近侧螺纹区段20728的节距。换句话说，远侧螺纹区段20730的导程大于近侧螺纹区段20728的导程。在一种布置中，远侧螺纹区段20730的导程可为近侧螺纹区段20728的导程的大约两倍。另外，可在近侧螺纹区段20728和远侧螺纹区段20730之间提供死空间20731。在至少一个示例中，砧座驱动轴20710可由挤出齿轮原件制成为一体。15-17 illustrate portions of anend effector 20500 configured to cut and staple tissue. Theend effector 20500 includes anelongated channel 20510 configured to operably support a surgicalstaple cartridge 20600 therein. The end effector includes ananvil assembly 20700 that operably supports an anvilconcentric drive member 20710 for operably driving the firing member 20720 through theend effector 20500. Anvilconcentric drive member 20710 may be centrally disposed withinanvil frame 20712 and extend substantially its length, for example. In the illustrated embodiment, the anvilconcentric drive member 20710 includes an anvil drive shaft that includes adistal bearing lug 20714 and a proximal bearing lug 20716. Thedistal bearing ears 20714 are rotatably received in adistal bearing housing 20718 supported in bearing pockets in theanvil frame 20712. The proximal bearing ears 20716 are rotatably supported in theanvil assembly 20700 by a floating bearing housing 20720 that is movably supported in bearing pockets formed in theproximal anvil portion 20724 20722. See Figure 16. The proximal bearing housing arrangement and the distal bearing housing arrangement can be used to prevent or at least minimize the occurrence of compressive forces on theanvil drive shaft 20710 that might otherwise cause theanvil drive shaft 20710 to buckle under high force conditions.Anvil drive shaft 20710 also includes driven firing gear 20726 , proximal threaded orhelical section 20728 and distal threaded orhelical section 20730 . In the arrangement shown, the proximal threadedsection 20728 has a first length and the distal threadedsection 20730 has a distal length that is greater than the first length. In the arrangement shown, the pitch of the distal threadedsections 20730 is greater than the pitch of the proximal threadedsections 20728. In other words, the lead of the distal threadedsection 20730 is greater than the lead of the proximal threadedsection 20728. In one arrangement, the lead of the distal threadedsection 20730 may be approximately twice the lead of the proximal threadedsection 20728. Additionally, adead space 20731 may be provided between the proximal threadedsection 20728 and the distal threadedsection 20730. In at least one example, theanvil drive shaft 20710 can be made in one piece from extruded gear elements.

为了便于各种砧座部件的组装，砧座组件20700包括砧座盖20740，该砧座盖20740可通过焊接、按扣特征等附接到砧座框架20712。此外，砧座组件20700包括一对砧座板或钉形成板20742，其可在其底部表面上包含各种图案的钉形成凹坑，其对应于被支撑在细长通道20510中的外科钉仓20600中的钉布置。钉形成板20742可由金属或类似材料制成并且焊接到或以其它方式附接到砧座框架20712。在其它布置中，也可采用单个砧板，在该砧板中具有狭槽以容纳击发构件。此种砧板或板的组合可用于改善砧座组件的整体刚度。例如，(一个或多个)砧板可为平的并且具有“铸造”在砧板中的钉形成凹坑。To facilitate assembly of the various anvil components, theanvil assembly 20700 includes ananvil cover 20740 that can be attached to theanvil frame 20712 by welding, snap features, or the like. Additionally, theanvil assembly 20700 includes a pair of anvil plates or staple-formingplates 20742 that can contain various patterns of staple-forming pockets on their bottom surfaces that correspond to surgical staple cartridges supported in theelongated channels 20510 The peg arrangement in the 20600. Thestaple forming plate 20742 may be made of metal or similar material and welded or otherwise attached to theanvil frame 20712. In other arrangements, a single anvil with a slot therein to accommodate the firing member may also be employed. Such anvil or plate combinations can be used to improve the overall stiffness of the anvil assembly. For example, the anvil block(s) may be flat and have spike-forming pockets "cast" into the anvil block.

如在图15和图18至图20中可以看到的，外科端部执行器20500包括击发构件20800，该击发构件20800具有主体部分20802，该主体部分20802具有形成在其上或以其它方式附接到其的刀螺母部分20804。刀螺母部分20804被构造成接收在砧座驱动轴20710上。在刀螺母部分20804中形成远侧螺纹节结20806和近侧螺纹节结20808，该远侧螺纹节结20806和近侧螺纹节结20808被构造成接合近侧螺纹区段20728和远侧螺纹区段20730。远侧螺纹节结20806相对于死空间20731的长度与近侧螺纹节结20808间隔开，使得当刀螺母部分20804跨越死空间20731时，远侧螺纹节结20806与远侧螺纹区段20730螺纹接合，并且近侧螺纹节结20808与近侧螺纹区段20728螺纹接合。另外，砧座接合突片20810从刀螺母20804的相对侧向部分侧向突出，并且各自取向成与附接到砧座框架20712的对应钉形成板20742接合。击发构件20800还包括从主体部分20800的每个侧向侧突出的通道接合突片20820。击发构件20800还包括组织切割表面20822。As can be seen in Figures 15 and 18-20, thesurgical end effector 20500 includes a firingmember 20800 having abody portion 20802 having abody portion 20802 formed thereon or otherwise attachedKnife nut portion 20804 to which it is attached.Knife nut portion 20804 is configured to be received onanvil drive shaft 20710. A distal threadednodule 20806 and a proximal threadednodule 20808 are formed in theknife nut portion 20804, the distal threadednodule 20806 and the proximal threadednodule 20808 being configured to engage the proximal threadedsection 20728 and the distal threadedregion segment 20730. The length of the distal threadednodules 20806 relative to the length of thedead space 20731 is spaced from the proximal threadednodules 20808 such that when theknife nut portion 20804 spans thedead space 20731, the distal threadednodules 20806 are in threaded engagement with the distal threadedsections 20730 , and the proximal threadednode 20808 is threadedly engaged with the proximal threadedsegment 20728. Additionally,anvil engagement tabs 20810 project laterally from opposing lateral portions of theknife nut 20804 and are each oriented to engage a correspondingstaple forming plate 20742 attached to theanvil frame 20712. The firingmember 20800 also includeschannel engagement tabs 20820 protruding from each lateral side of thebody portion 20800. The firingmember 20800 also includes atissue cutting surface 20822.

砧座驱动轴20710在第一旋转方向上的旋转将导致击发构件20800从第一位置轴向移动到第二位置。类似地，砧座驱动轴20710在第二旋转方向上的旋转将导致击发构件20800从第二位置轴向缩回到第一位置。砧座驱动轴20710最终从近侧驱动轴(未示出)获得旋转运动，该近侧驱动轴可操作地与远侧动力轴20830对接。在所示的布置中，远侧动力轴20830具有远侧驱动齿轮20832，其被构造用于当砧座组件20710处于闭合位置时与砧座驱动轴20710上的从动击发齿轮20726啮合接合。砧座驱动轴20710被称为与远侧动力轴20830“分离且不同”。也就是说，例如至少在所示的布置中，砧座驱动轴20710不与远侧动力轴20830同轴对准，并且不形成远侧动力轴20830的一部分。另外，例如，当砧座组件20700在打开位置和闭合位置之间运动时，砧座驱动轴20710能够相对于远侧动力轴20830移动。近侧驱动轴可最终通过支撑在壳体中的马达旋转，该壳体附接到联接到外科端部执行器20500的轴组件。壳体可包括手持组件或机器人控制系统的一部分。Rotation of theanvil drive shaft 20710 in the first rotational direction will cause the firingmember 20800 to move axially from the first position to the second position. Similarly, rotation of theanvil drive shaft 20710 in the second rotational direction will cause the firingmember 20800 to be axially retracted from the second position to the first position.Anvil drive shaft 20710 ultimately obtains rotational motion from a proximal drive shaft (not shown) that operably interfaces withdistal power shaft 20830. In the arrangement shown, thedistal power shaft 20830 has adistal drive gear 20832 configured for meshing engagement with a driven firing gear 20726 on theanvil drive shaft 20710 when theanvil assembly 20710 is in the closed position.Anvil drive shaft 20710 is referred to as "separate and distinct" fromdistal power shaft 20830. That is, for example, at least in the arrangement shown, theanvil drive shaft 20710 is not coaxially aligned with thedistal power shaft 20830 and does not form part of thedistal power shaft 20830. Additionally, for example, theanvil drive shaft 20710 can move relative to thedistal power shaft 20830 when theanvil assembly 20700 is moved between the open and closed positions. The proximal drive shaft is ultimately rotatable by a motor supported in a housing attached to a shaft assembly coupled to thesurgical end effector 20500. The housing may include a handheld assembly or part of a robotic control system.

在所示的布置中，砧座组件20700通过向远侧推进闭合管20900而闭合。如图15中可以看到的，闭合管20900包括内螺纹闭合螺母20902，其被构造用于与形成在远侧动力轴20830上的闭合螺纹节段20834螺纹接合。远侧动力轴20830的初始旋转将向远侧驱动闭合管20900以将砧座组件20700凸轮致动至闭合位置。远侧动力轴20830在相对方向上的旋转将在近侧方向上驱动闭合管20900，以准许砧座组件20700移动到打开位置。In the arrangement shown, theanvil assembly 20700 is closed by advancing theclosure tube 20900 distally. As can be seen in FIG. 15 , theclosure tube 20900 includes an internally threadedclosure nut 20902 configured for threaded engagement with a closure threadedsegment 20834 formed on thedistal power shaft 20830. Initial rotation of thedistal power shaft 20830 will drive theclosure tube 20900 distally to cam actuate theanvil assembly 20700 to the closed position. Rotation of thedistal power shaft 20830 in the opposite direction will drive theclosure tube 20900 in the proximal direction to permit movement of theanvil assembly 20700 to the open position.

转到图18至图20，通道包括一对向内延伸的纵向保持突片20512，在所述纵向保持突片之间具有狭槽空间20514，以容纳击发构件20800的纵向移动。另外，通道20510包括近侧锁定腔体20516，其邻近保持突片20512。锁定腔体20516过渡到远侧击发腔体，远侧击发腔体与突片20512和突片之间的空间20514共同延伸。锁定腔体20516大于远侧击发腔体，以准许击发构件20800枢转到图18中所示的位置。当处于该位置时，击发构件主体20802脱出与狭槽空间的对准，并且突片20820脱出与远侧击发腔体20518的对准。当处于该位置时，从击发构件20800突出的突片20820中的一个与保持突片20512中的一个对准，因此防止击发构件20800被纵向推进通过通道20510。当砧座驱动轴20710最初旋转并且具有处于起始位置的滑动件的外科钉仓尚未安装在通道20510中时，击发构件20800将枢转到该“锁定”位置。然而，当具有处于起始位置的滑动件的仓已经安装在通道20510中时，滑动件将用于接触或以其它方式与击发构件20800对接，以将击发构件20800定位并保持成与保持突片20512之间的空间20514对准。参见图19。因此，砧座驱动轴20710的继续旋转将向远侧驱动击发构件20800通过通道20510，如图20所示。因此，此种布置将防止临床医生无意地致动砧座驱动轴20710以向远侧驱动击发构件20800通过通道20510，除非已经在通道中安装了具有处于起始位置的滑动件的未用完的外科钉仓。18-20, the channel includes a pair of inwardly extendinglongitudinal retention tabs 20512 with slottedspaces 20514 therebetween to accommodate longitudinal movement of the firingmember 20800. Additionally, thechannel 20510 includes aproximal locking cavity 20516 adjacent theretention tab 20512. The lockingcavity 20516 transitions to a distal firing cavity coextensive with thetabs 20512 and thespace 20514 between the tabs. The lockingcavity 20516 is larger than the distal firing cavity to permit pivoting of the firingmember 20800 to the position shown in FIG. 18 . When in this position, the firingmember body 20802 is out of alignment with the slot space and thetabs 20820 are out of alignment with the distal firing cavity 20518. When in this position, one of thetabs 20820 protruding from the firingmember 20800 is aligned with one of the retainingtabs 20512, thus preventing the firingmember 20800 from being advanced longitudinally through thechannel 20510. When theanvil drive shaft 20710 is initially rotated and the surgical staple cartridge with the slider in the starting position has not been installed in thechannel 20510, the firingmember 20800 will pivot to this "locked" position. However, when the cartridge with the slider in the home position has been installed in thechannel 20510, the slider will be used to contact or otherwise interface with the firingmember 20800 to position and hold the firingmember 20800 in contact with the retainingtabs Space 20514 between 20512 is aligned. See Figure 19. Accordingly, continued rotation of theanvil drive shaft 20710 will drive the firingmember 20800 distally through thechannel 20510, as shown in FIG. 20 . Thus, this arrangement will prevent the clinician from inadvertently actuating theanvil drive shaft 20710 to drive the firingmember 20800 distally through thechannel 20510 unless an unused spool with the slider in the starting position has been installed in the channel Surgical staple cartridge.

在其它布置中，可以电的方式确定已经正确地坐置在外科切割和缝合端部执行器的通道中的未用完的钉仓内的处于正确位置的滑动件的检测。例如，这可通过滑动件上的接触件实现，当滑动件处于已经正确地坐置在通道中的仓中的起始位置时，该接触件使电路接通。在击发时，电路被打开并且不准许进一步击发，直到电路再次闭合。In other arrangements, detection of a properly positioned sled within an unused staple cartridge that has been properly seated in the channel of the surgical cutting and stapling end effector can be determined electrically. This can be accomplished, for example, by means of contacts on the slider which make the circuit close when the slider is in the starting position in the bin already seated correctly in the channel. Upon firing, the circuit is opened and no further firing is permitted until the circuit is closed again.

如上所述，用于第一次抓握、夹紧、缝合和/或切割组织的缝合组件在本领域中是公知的。例如，先前的缝合组件，诸如美国专利号5,865,361中公开的那些，已经包括了可操作地连接到柄部组件的装载单元。1999年2月2日公布的名称为“外科缝合设备(SURGICALSTAPLING APPARATUS)”的美国专利号5,865,361的公开内容以引用方式全文并入本文。虽然这些先前的缝合组件的柄部组件被构造用于多种用途，但是装载单元被构造用于单次使用。在每个装载单元用完或至少部分用完之后，将装载单元从柄部组件中移除，然后如果需要，则用新的或未用完的装载单元替换。这些先前的装载单元的构造不准许替换装载单元的仓部分，使得可以再次使用用完的装载单元。As mentioned above, stapling assemblies for first grasping, clamping, stapling and/or cutting tissue are known in the art. For example, previous suturing assemblies, such as those disclosed in US Pat. No. 5,865,361, have included a loading unit operably connected to the handle assembly. The disclosure of US Patent No. 5,865,361, issued February 2, 1999, entitled "SURGICAL STAPLING APPARATUS," is incorporated herein by reference in its entirety. While the handle assemblies of these previous suture assemblies were configured for multiple uses, the loading unit was configured for single use. After each loading unit is exhausted or at least partially exhausted, the loading unit is removed from the handle assembly and then replaced with a new or unused loading unit if necessary. The configuration of these previous loading units does not permit replacement of the bin portion of the loading unit so that the spent loading unit can be reused.

美国专利申请公布号2012/0286021公开了另选的缝合组件，其包括包括砧座的第一夹具和包括钉仓的第二夹具。2012年11月15日公布的名称为“可替换钉仓(REPLACEABLESTAPLE CARTRIDGE)”的美国专利申请公布号2012/0286021的全部公开内容以引用方式并入本文。与先前的装载单元不同，这些缝合组件的第二夹具可以从装载单元完全移除，然后用另一个第二夹具替换，可能是在前一个第二夹具已经用完之后。值得注意的是，这些缝合组件的整个第二夹具被替换(不仅仅是第二夹具的一部分)，如2006年1月24日公布的名称为“具有用完的仓闭锁件的外科缝合器械(SURGICAL STAPLING INSTRUMENT HAVING ASPENT CARTRIDGE LOCKOUT)”的美国专利号6,988,649中所公开的，该专利的整个公开内容以引用方式并入本文。US Patent Application Publication No. 2012/0286021 discloses an alternative stapling assembly that includes a first clamp that includes an anvil and a second clamp that includes a staple cartridge. The entire disclosure of US Patent Application Publication No. 2012/0286021, published November 15, 2012, entitled "REPLACEABLESTAPLE CARTRIDGE," is incorporated herein by reference. Unlike previous loading units, the second clamp of these suture assemblies can be completely removed from the loading unit and then replaced with another second clamp, possibly after the previous second clamp has been used up. Notably, the entire second clamp of these suturing assemblies is replaced (not just a portion of the second clamp), as published on January 24, 2006 entitled "Surgical Stapling Instruments with Spent Cartridge Locks ( SURGICAL STAPLING INSTRUMENT HAVING ASPENT CARTRIDGE LOCKOUT)" US Patent No. 6,988,649, the entire disclosure of which is incorporated herein by reference.

然而，在美国专利申请公布号2012/0286021中公开的缝合组件是有缺陷的。比如，在美国专利申请公布号2012/0286021中公开的缝合组件包括切割构件，即使第二夹具未附接到缝合组件，该切割构件亦可以向远侧推进。因此，切割构件可无意地暴露于患者的组织。下面进一步讨论了对这些缝合组件的各种改善。However, the suture assembly disclosed in US Patent Application Publication No. 2012/0286021 is deficient. For example, the stapling assembly disclosed in US Patent Application Publication No. 2012/0286021 includes a cutting member that can be advanced distally even if the second clip is not attached to the stapling assembly. Thus, the cutting member may be inadvertently exposed to the patient's tissue. Various improvements to these suture assemblies are discussed further below.

现在转向图21，外科器械系统21000包括柄部21010和附接到柄部21010的轴21020的缝合组件或装载单元21030。主要参考图22，装载单元21030包括近侧端部或卡口连接器21032，其构造成将装载单元21030可释放地附接到轴21020。类似于美国专利申请公布号2012/0286021中公开的缝合组件，装载单元21030包括砧座21040和可附接的仓夹具21050。仓夹具21050一旦附接到装载单元21030，就可在打开位置(图21)和闭合或夹紧位置之间枢转。Turning now to FIG. 21 , asurgical instrument system 21000 includes ahandle 21010 and a stapling assembly orloading unit 21030 attached to ashaft 21020 of thehandle 21010 . Referring primarily to FIG. 22 , theloading unit 21030 includes a proximal end orbayonet connector 21032 configured to releasably attach theloading unit 21030 to theshaft 21020 . Similar to the stapling assembly disclosed in US Patent Application Publication No. 2012/0286021, theloading unit 21030 includes ananvil 21040 and anattachable cartridge clamp 21050. Once attached to theloading unit 21030, themagazine clamp 21050 can be pivoted between an open position (FIG. 21) and a closed or clamped position.

柄部21010包括致动器或触发器21014，其可朝向柄部21010的手枪式夹持件21012旋转，以向远侧驱动装载单元21030的击发杆。在触发器21014的第一冲程期间，击发杆接合仓夹具21050并将仓夹具21050移动到其闭合位置。在触发器21014的一个或多个后续冲程期间，击发杆被推进通过仓夹具21050。仓夹具21050包括可移除地存储在仓夹具中的多个钉，当击发杆向远侧推进通过仓夹具21050时，该多个钉从仓夹具21050射出。更具体地，如本文其它地方更详细地讨论的，击发杆进入仓夹具21050并向远侧推动存储在仓夹具21060中的滑动件，这继而又将钉驱动离开仓夹具21050。Thehandle 21010 includes an actuator or trigger 21014 that is rotatable toward thepistol grip 21012 of thehandle 21010 to drive the firing rod of theloading unit 21030 distally. During the first stroke of thetrigger 21014, the firing rod engages thecartridge clamp 21050 and moves thecartridge clamp 21050 to its closed position. During one or more subsequent strokes of thetrigger 21014, the firing rod is advanced through thecartridge clamp 21050. Thecartridge holder 21050 includes a plurality of staples removably stored in the cartridge holder that are ejected from thecartridge holder 21050 as the firing rod is advanced distally through thecartridge holder 21050 . More specifically, as discussed in greater detail elsewhere herein, the firing rod enters thecartridge clamp 21050 and pushes distally a slider stored in the cartridge clamp 21060, which in turn drives the staples away from thecartridge clamp 21050.

主要参考图22，装载单元21030还包括关节运动接头21036，砧座21040和仓夹具21050可以围绕该关节运动接头21036进行关节运动。装载单元21030包括关节运动驱动器，该关节运动驱动器被构造成使砧座21040和仓夹具21050围绕关节运动接头21036进行关节运动。关节运动驱动器可操作地与关节运动致动器21016联接，该关节运动致动器21016可旋转以推动或拉动关节运动驱动器，这取决于关节运动致动器21016旋转的方向。22, theloading unit 21030 also includes an articulation joint 21036 about which theanvil 21040 and thecartridge clamp 21050 can be articulated.Loading unit 21030 includes an articulation driver configured to articulateanvil 21040 andcartridge clamp 21050 aboutarticulation joint 21036 . The articulation driver is operably coupled to thearticulation actuator 21016, which is rotatable to push or pull the articulation driver, depending on the direction in which thearticulation actuator 21016 is rotated.

在图23和图24中示出了另选的外科器械系统21100。系统21100包括柄部21110和可附接的装载单元21130。与上文类似，装载单元21130包括砧座夹具21040和可移除地附接的仓夹具21050。装载单元21130还包括关节运动接头21138和挠性接头21136，关节运动接头21138和挠性接头21136被构造成准许端部执行器相对于装载单元21130的轴部分21120进行关节运动。轴部分21120包括近侧连接器21122，该近侧连接器21122被构造成将装载单元21130附接到柄部21110。主要参考图25，近侧连接器21122包括可旋转输入21128，其可操作地与柄部21110的可旋转输出21118接合。每个可旋转输入21128是驱动系统的一部分，该驱动系统例如围绕挠性接头21136和/或关节运动接头21128使装载单元21130进行关节运动，闭合仓夹具21050，和/或从仓夹具21050击发钉。柄部21110包括控制器21114和21116，其可以用于操作装载单元21130的驱动系统。2013年10月24日公布的名称为“用于内窥镜检查程序的设备(APPARATUS FOR ENDOSCOPIC PROCEDURES)”的美国专利申请公布号2013/0282052的公开内容以引用方式全文并入本文。An alternativesurgical instrument system 21100 is shown in FIGS. 23 and 24 .System 21100 includes ahandle 21110 and anattachable loading unit 21130. Similar to the above, theloading unit 21130 includes ananvil clamp 21040 and a removably attachedcartridge clamp 21050. Theloading unit 21130 also includes anarticulation joint 21138 and a flexible joint 21136 configured to permit articulation of the end effector relative to theshaft portion 21120 of theloading unit 21130. Theshaft portion 21120 includes aproximal connector 21122 configured to attach theloading unit 21130 to thehandle 21110. Referring primarily to FIG. 25 , theproximal connector 21122 includes arotatable input 21128 operatively engaged with therotatable output 21118 of thehandle 21110 . Eachrotatable input 21128 is part of a drive system that, for example, articulates theloading unit 21130 about the flex joint 21136 and/or the articulation joint 21128, closes thecartridge clamp 21050, and/or fires staples from thecartridge clamp 21050 . Thehandle 21110 includescontrols 21114 and 21116, which may be used to operate the drive system of theloading unit 21130. The disclosure of US Patent Application Publication No. 2013/0282052, published October 24, 2013, entitled "APPARATUS FOR ENDOSCOPIC PROCEDURES," is incorporated herein by reference in its entirety.

除上述之外，钉仓夹具21050可移除地附接到装载单元21030的砧座夹具21040。主要参考图26和图27，砧座夹具21040的近侧端部包括从其相对侧延伸的附接突出部21042。钉仓夹具21050的近侧端部包括限定在近侧端部中的凹陷部21052，凹陷部21052被构造成接收附接突出部21042。砧座夹具21040固定地附接到装载单元21030的框架，并且附接突出部21042从砧座夹具21040固定地延伸。在至少一种情况下，砧座夹具21040和/或附接突出部21042与砧座部分21030的框架一体地形成。In addition to the above, thecartridge clamp 21050 is removably attached to theanvil clamp 21040 of theloading unit 21030. Referring primarily to Figures 26 and 27, the proximal end of theanvil clamp 21040 includesattachment tabs 21042 extending from opposite sides thereof. The proximal end of thecartridge clip 21050 includes arecess 21052 defined in the proximal end, therecess 21052 being configured to receive theattachment protrusion 21042.Anvil clamp 21040 is fixedly attached to the frame ofloading unit 21030 , andattachment tabs 21042 extend fixedly fromanvil clamp 21040 . In at least one instance, theanvil clamp 21040 and/or theattachment tabs 21042 are integrally formed with the frame of theanvil portion 21030.

钉仓夹具21050还包括夹子21056，夹子21056被构造成接合并抓住附接突出部21042。每个夹子21056定位在仓夹具21050中限定的狭槽21055内。当仓夹具21050附接到装载单元21030时，夹子21056围绕附接突出部21042折曲。当仓夹具21050完全附接到装载单元21030时，夹子21056弹性地卡扣或朝向它们的未折曲构造返回并且将附接突出部21042保持在凹陷部21052中。Thecartridge clamp 21050 also includes aclip 21056 configured to engage and grasp theattachment tab 21042. Eachclip 21056 is positioned within aslot 21055 defined in thecartridge clamp 21050. When themagazine clip 21050 is attached to theloading unit 21030, theclip 21056 flexes around theattachment tab 21042. When the magazine clips 21050 are fully attached to theloading unit 21030 , theclips 21056 snap or return toward their undeflexed configuration elastically and retain theattachment tabs 21042 in therecesses 21052 .

除上述之外，当夹子21056与附接突出部21042接合并且附接突出部21042完全坐置在凹陷部21052中时，仓夹具21050正确地附接到装载单元21030。也就是说，装载单元21030不包括被构造成检测仓夹具21050是否正确地附接到装载单元21030的感测系统。现在转到图28至图32，装载单元21130包括系统，该系统被构造成检测钉仓夹具21150是否正确地附接到装载单元21130的砧座夹具21140，如下面更详细地描述的。In addition to the above, when theclip 21056 is engaged with theattachment tab 21042 and theattachment tab 21042 is fully seated in therecess 21052, thebin clip 21050 is properly attached to theloading unit 21030. That is, theloading unit 21030 does not include a sensing system configured to detect whether themagazine clamp 21050 is properly attached to theloading unit 21030. Turning now to FIGS. 28-32, theloading unit 21130 includes a system configured to detect whether thestaple cartridge clamp 21150 is properly attached to theanvil clamp 21140 of theloading unit 21130, as described in more detail below.

装载单元21130包括当钉仓夹具21150正确地附接到装载单元21130时接通或闭合的电路。电路与外科器械系统的微处理器或控制器通信。控制器位于外科器械系统的柄部中；然而，控制器可以位于外科器械系统的任何合适的零件中，例如装载单元21130。另选地，控制器可以位于外科器械组件的壳体中，该壳体附接到机器人外科系统和/或在机器人外科系统本身中。在任何情况下，控制器与电动马达通信，该电动马达驱动外科器械系统的钉击发系统。Theloading unit 21130 includes an electrical circuit that is turned on or closed when thecartridge clamp 21150 is properly attached to theloading unit 21130. The circuit communicates with the microprocessor or controller of the surgical instrument system. The controller is located in the handle of the surgical instrument system; however, the controller may be located in any suitable part of the surgical instrument system, such as theloading unit 21130. Alternatively, the controller may be located in a housing of the surgical instrument assembly that is attached to the robotic surgical system and/or within the robotic surgical system itself. In any event, the controller is in communication with an electric motor that drives the staple firing system of the surgical instrument system.

当控制器检测到钉仓没有正确地附接到装载单元21130时，除上述之外，控制器可以防止电动马达驱动钉击发系统通过钉击发冲程。在至少一个此种情况下，控制器可以打开电源(例如诸如电池)和电动马达之间的开关，以防止电力供应到电动马达。当控制器检测到钉仓21150正确地附接到装载单元21130时，控制器可以准许电动马达当由外科器械系统的使用者致动时从电池接收电力并且驱动钉击发系统通过钉击发冲程。在至少一个此种情况下，控制器可以例如闭合电池和电动马达之间的开关。In addition to the above, the controller may prevent the electric motor from driving the staple firing system through the staple firing stroke when the controller detects that the staple cartridge is not properly attached to theloading unit 21130. In at least one such situation, the controller may open a switch between a power source (eg, such as a battery) and the electric motor to prevent power from being supplied to the electric motor. When the controller detects that thestaple cartridge 21150 is properly attached to theloading unit 21130, the controller may permit the electric motor to receive power from the battery when actuated by a user of the surgical instrument system and drive the staple firing system through the staple firing stroke. In at least one such situation, the controller may, for example, close a switch between the battery and the electric motor.

装载单元21130的电路包括延伸穿过装载单元21130的轴部分的导体21147(图30和图32)，以及定位在附接突出部21142中的每个周围的接触件21146。导体21147中的每个电联接到微处理器和接触件21146。钉仓21150包括电路的一部分，当钉仓21150与附接突出部21142完全接合时，该电路的一部分使电路接通。参考图31，钉仓21150中的电路的一部分包括位于凹陷部21052中的每个中的接触件21159和在接触件21159之间延伸并与接触件21159电联接的导体或迹线21157。夹子21056被构造成将钉仓夹具21150的接触件21159保持抵靠围绕附接部分21142延伸的接触件21146。在至少一种情况下，夹子21056由导电材料构成并且与迹线21157通信。在此类情况下，夹子21056是钉仓21150中的电路的零件。在任何情况下，当钉仓夹具21150与装载单元21130脱离时，电路断开或打开，并且微处理器可以检测到钉仓夹具21150不再附接到装载单元21130。The electrical circuit of theloading unit 21130 includes conductors 21147 ( FIGS. 30 and 32 ) extending through the shaft portion of theloading unit 21130 , andcontacts 21146 positioned around each of theattachment tabs 21142 . Each of theconductors 21147 is electrically coupled to the microprocessor andcontacts 21146. Thestaple cartridge 21150 includes a portion of an electrical circuit that closes the electrical circuit when thestaple cartridge 21150 is fully engaged with theattachment tabs 21142. Referring to FIG. 31 , a portion of the electrical circuit in thestaple cartridge 21150 includescontacts 21159 located in each of therecesses 21052 and conductors or traces 21157 extending between thecontacts 21159 and electrically coupled to thecontacts 21159 . Theclip 21056 is configured to hold thecontacts 21159 of thecartridge clamp 21150 against thecontacts 21146 extending around theattachment portion 21142. In at least one instance,clip 21056 is constructed of a conductive material and communicates withtrace 21157. In such cases, theclip 21056 is part of the circuitry in thestaple cartridge 21150. In any event, when thecartridge clamp 21150 is disengaged from theloading unit 21130, the circuit is broken or opened, and the microprocessor can detect that thecartridge clamp 21150 is no longer attached to theloading unit 21130.

除上述之外，如果仅接触件21159中的一个与其相应的接触件21146接合，则控制器可以确定钉仓夹具21150不正确地附接到装载单元21130。在此类情况下，电路将处于打开状态，因此，微处理器将把不正确地组装的钉仓夹具21150视为缺失的仓夹具21150，并防止电动马达被致动以执行钉击发冲程。在各种情况下，外科器械系统可以包括指示灯和/或反馈系统，其向外科器械系统的使用者传递钉仓夹具检测电路尚未闭合的情况。响应于此，使用者可以调查情况并正确地坐置钉仓夹具21150以闭合检测电路。In addition to the above, if only one of thecontacts 21159 is engaged with itscorresponding contact 21146, the controller may determine that thecartridge clamp 21150 is incorrectly attached to theloading unit 21130. In such a case, the electrical circuit would be open, so the microprocessor would treat the incorrectly assembledstaple cartridge clamp 21150 as a missingcartridge clamp 21150 and prevent the electric motor from being actuated to perform the staple firing stroke. In various instances, the surgical instrument system may include an indicator light and/or a feedback system that communicates to a user of the surgical instrument system that the cartridge clamp detection circuit has not been closed. In response to this, the user can investigate the situation and properly seat thecartridge clamp 21150 to close the detection circuit.

如图31所示，导体21157侧向延伸穿过仓夹具21150。当击发构件被向远侧推进通过仓夹具21150时，击发构件可以横切和/或断开导体21157并打开夹具检测电路。此时，控制器可以准许电动马达被操作以向远侧推进击发构件，直到击发构件缩回到其未击发位置。在击发构件已缩回到其未击发位置之后，控制器然后可以防止电动马达的重新操作，直到未用完的仓夹具21150正确地附接到装载单元21130。因此，装载单元21130的电路可以用作缺失的仓闭锁件、不正确地附接的仓闭锁件和用完的仓闭锁件。As shown in FIG. 31,conductors 21157 extend laterally throughcartridge clamp 21150. When the firing member is advanced distally through thecartridge clamp 21150, the firing member can traverse and/or break theconductor 21157 and open the clamp detection circuit. At this point, the controller may permit the electric motor to be operated to advance the firing member distally until the firing member is retracted to its unfired position. After the firing member has been retracted to its unfired position, the controller may then prevent re-operation of the electric motor until theunused cartridge clamp 21150 is properly attached to theloading unit 21130. Thus, the circuitry of theloading unit 21130 may function as a missing bin latch, an incorrectly attached bin latch, and a spent bin latch.

除了上述之外或代替上述内容，滑动件21170可以包括导电部分，当滑动件21170处于其未击发位置时，该导电部分电连接侧向夹具接触件21159和/或导电夹子21056。在至少一种情况下，滑动件21170包括从滑动件21170的一个侧向侧延伸到另一个的导体和/或迹线。当滑动件21170向远侧推进时，滑动件21170的导电部分不再与接触件21159和/或夹子21056电通信，并且夹具检测电路打开。在夹具组件还包括导体21157的程度上，可以切割或断开导体21157以打开如上所述的夹具检测电路。在各种情况下，例如，在导体21157被切割或断开的同时，滑动件21170可以从夹具检测电路位移。在任何情况下，导电滑动件21170可以提供用完的仓闭锁件。In addition to or in lieu of the above, theslider 21170 may include a conductive portion that electrically connects thelateral clamp contacts 21159 and/or theconductive clips 21056 when theslider 21170 is in its unfired position. In at least one instance, theslider 21170 includes conductors and/or traces that extend from one lateral side of theslider 21170 to the other. When theslider 21170 is advanced distally, the conductive portion of theslider 21170 is no longer in electrical communication with thecontacts 21159 and/or theclip 21056, and the clip detection circuit opens. To the extent that the clamp assembly also includesconductors 21157,conductors 21157 can be cut or broken to open the clamp detection circuit as described above. In various situations, for example, whileconductor 21157 is being cut or broken,slider 21170 can detect circuit displacement from the fixture. In any event, theconductive slide 21170 can provide a spent cartridge closure.

在各种另选实施方案中，当击发构件向远侧推进时，加载单元的电路闭锁件不被横切。现在转向图34，装载单元21230的钉仓夹具21250包括仓主体21251、限定在仓主体21251中的多个钉腔体21258，以及限定在仓主体21251中的纵向狭槽21259，该狭槽被构造成接收击发构件的一部分。类似于钉仓夹具21150，钉仓夹具21250包括装载单元电路的一部分。钉仓夹具21250中的电路的一部分包括限定在凹陷部21052中的电接触件，例如诸如接触件21159，以及设置在纵向狭槽21251的相对侧上的顺应性电接触件21257。每个顺应性接触件21257经由例如延伸通过仓主体21251的导体或迹线与接触件21052电通信。In various alternative embodiments, the circuit lockout of the loading unit is not transected when the firing member is advanced distally. Turning now to FIG. 34, thestaple cartridge clamp 21250 of theloading unit 21230 includes acartridge body 21251, a plurality ofstaple cavities 21258 defined in thecartridge body 21251, and alongitudinal slot 21259 defined in thecartridge body 21251 that is configured form part of the receiving firing member. Similar to thecartridge clamp 21150, thecartridge clamp 21250 includes a portion of the loading unit circuitry. A portion of the electrical circuit incartridge clamp 21250 includes electrical contacts, such ascontacts 21159, for example, defined inrecesses 21052, and compliantelectrical contacts 21257 disposed on opposite sides oflongitudinal slot 21251. Eachcompliant contact 21257 is in electrical communication with thecontact 21052 via, for example, conductors or traces extending through thecartridge body 21251.

顺应性接触件21257被构造成在钉仓夹具21250组装到装载单元21250时接合装载单元21230的砧座夹具21240。更具体地，顺应性接触件21257接合限定在砧座夹具21240中的导电通路21247，其电连接顺应性接触件21257，并且此时电路已经闭合。顺应性接触件21257保持恒定地与导电通路21247接合，即当仓夹具21250处于打开位置时，当仓夹具21250处于闭合位置时，以及当仓夹具21250在其打开位置和闭合位置之间运动时。当击发构件向远侧推进时，击发构件穿过限定在接触件21257之间的间隙，因此，电夹具检测电路不被横切。此种布置可以提供缺失的仓夹具闭锁件和/或不正确地附接的仓夹具闭锁件。Thecompliant contact 21257 is configured to engage theanvil clamp 21240 of theloading unit 21230 when thecartridge clamp 21250 is assembled to theloading unit 21250. More specifically, thecompliant contact 21257 engages aconductive pathway 21247 defined in theanvil clamp 21240, which electrically connects thecompliant contact 21257, and the electrical circuit has now been closed. Thecompliant contacts 21257 remain in constant engagement with theconductive paths 21247, ie when thecartridge clamp 21250 is in the open position, when thecartridge clamp 21250 is in the closed position, and when thecartridge clamp 21250 is moved between its open and closed positions. When the firing member is advanced distally, the firing member passes through the gap defined between thecontacts 21257, thus, the electrical clamp detection circuit is not transected. Such an arrangement may provide for a missing cartridge clamp latch and/or an incorrectly attached cartridge clamp latch.

除上述之外，顺应性接触件21257可以包括弹簧，该弹簧被构造成将钉仓夹具21250偏压到打开位置。当钉仓夹具21250移动到其闭合位置时，顺应性接触件21257在钉仓夹具21250和砧座21240之间被压缩。顺应性接触件21257连同电夹具检测电路的其它部分与缝合组件的金属或导电部分电绝缘，以便维持夹具检测电路的完整性并防止夹具检测电路短路。In addition to the above, thecompliant contact 21257 may include a spring configured to bias thecartridge clamp 21250 to the open position. When thecartridge clamp 21250 is moved to its closed position, thecompliant contacts 21257 are compressed between thecartridge clamp 21250 and theanvil 21240. Thecompliant contacts 21257, along with the rest of the electrical clip detection circuit, are electrically isolated from the metal or conductive parts of the suture assembly in order to maintain the integrity of the clip detection circuit and prevent shorting of the clip detection circuit.

除了诸如上述闭锁件之类的电或电子闭锁件之外或代替诸如上述闭锁件之类的电或电子闭锁件，例如，装载单元可以包括机械闭锁件，如果钉仓夹具没有正确附接到装载单元，则该机械闭锁件防止击发系统执行钉击发冲程。现在转到图33，钉仓夹具21150包括滑动件21170，当击发构件21160在钉击发冲程期间向远侧推进时，该滑动件21170被击发构件21160(图30)向远侧推动。钉仓夹具21150还包括闭锁构件21172，该闭锁构件21172可枢转地与仓夹具21150的仓主体21151接合。如美国专利申请公布号2012/0286021中所述，在滑动件21170已经在击发冲程期间至少部分地向远侧推进之后，闭锁构件21172被向内偏压到闭锁位置，这防止了仓夹具21150被重新击发。In addition to or in place of electrical or electronic latches such as the latches described above, for example, the loading unit may include a mechanical latch if the cartridge clamp is not properly attached to the load unit, the mechanical latch prevents the firing system from performing the staple firing stroke. Turning now to FIG. 33, thestaple cartridge clamp 21150 includes aslider 21170 that is pushed distally by the firing member 21160 (FIG. 30) as the firingmember 21160 is advanced distally during the staple firing stroke. Thestaple cartridge clamp 21150 also includes a latchingmember 21172 that pivotally engages thecartridge body 21151 of thecartridge clamp 21150. As described in US Patent Application Publication No. 2012/0286021, after theslider 21170 has been at least partially advanced distally during the firing stroke, the blockingmember 21172 is biased inwardly to the blocking position, which prevents thecartridge clamp 21150 from being pushed Refire.

虽然闭锁构件21172可以阻挡击发构件21160的远侧推进，但是如上所述，在某些情况下，击发构件21160可能够推动通过闭锁构件21172和在闭锁构件21172之间滑动。作为改善，闭锁构件21172中的一个或二者可以包括朝向击发构件21160向内延伸的闩锁或钩。当在滑动件21170已经向远侧推进之后闭锁构件21172向内偏压时，闩锁或钩可以在击发构件21160缩回到其未击发位置时接合在击发构件21160中限定的孔隙。一旦闩锁或钩定位在击发构件孔隙中，它们就可以防止击发构件21160向远侧推进通过已经用完的仓。此时，必须替换钉仓以解锁击发构件21160。While the blockingmember 21172 may block distal advancement of the firingmember 21160, as discussed above, under certain circumstances, the firingmember 21160 may be capable of being pushed through and slid between the blockingmembers 21172. As an improvement, one or both of the blockingmembers 21172 may include a latch or hook extending inwardly toward the firingmember 21160. When the blockingmember 21172 is biased inwardly after theslider 21170 has been advanced distally, the latch or hook can engage an aperture defined in the firingmember 21160 when the firingmember 21160 is retracted to its unfired position. Once the latch or hook is positioned in the firing member aperture, they can prevent the firingmember 21160 from being advanced distally through the spent cartridge. At this point, the staple cartridge must be replaced to unlock the firingmember 21160.

如上所述，可附接的钉仓夹具可以在打开位置和闭合位置之间运动，以将组织夹紧在打开位置和闭合位置之间。设想了其它实施方案，其中钉仓夹具可移除地附接到缝合器械，但是砧座夹具能够在打开位置和闭合位置之间运动。现在转向图35至图38，缝合组件21530包括可附接的钉仓夹具21550，其包括仓主体21551，以及另外的可枢转的砧座夹具21540。缝合组件21530还包括击发构件，例如诸如击发构件21160，其能够向远侧移动以接合砧座夹具21540并将砧座夹具21540移动到闭合位置。更具体地，击发构件21160包括被构造成接合仓夹具21550的第一凸轮构件21162和被构造成接合砧座夹具21540并使砧座夹具21540朝向仓夹具21550移动的第二凸轮构件21164。As described above, the attachable cartridge clamp can be moved between open and closed positions to clamp tissue therebetween. Other embodiments are contemplated in which the cartridge clamp is removably attached to the stapling instrument, but the anvil clamp is movable between open and closed positions. Turning now to FIGS. 35-38 , the staplingassembly 21530 includes an attachablestaple cartridge clamp 21550 that includes acartridge body 21551 , and an additionalpivotable anvil clamp 21540 . The staplingassembly 21530 also includes a firing member, such as, for example, a firingmember 21160, which can be moved distally to engage theanvil clamp 21540 and move theanvil clamp 21540 to a closed position. More specifically, the firingmember 21160 includes afirst cam member 21162 configured to engage thecartridge clamp 21550 and asecond cam member 21164 configured to engage and move theanvil clamp 21540 toward thecartridge clamp 21550.

缝合组件21530还包括机械闭锁件21572。闭锁件21572在框架枢轴21232处安装到缝合组件21530的框架。闭锁件21572向远侧延伸并由框架销21533支撑。闭锁件21572包括金属线；然而，闭锁件21572可以由任何合适的材料构成。闭锁件21572还包括限定在闭锁件中的细长凹陷部轨道21576，该轨道被构造成接收从击发构件21160延伸的闭锁销21166。主要参考图35，当闭锁件21572处于其锁定位置时，细长凹陷部轨道21276约束或限制击发构件21160的纵向位移。更具体地，凹陷部轨道21576被构造成准许击发构件21160向远侧推进以使砧座夹具21540在其打开位置和闭合位置之间运动，但是防止击发构件21160向远侧推进以执行击发冲程，除非闭锁件21572移动到其解锁位置，如下所述。Thesuturing assembly 21530 also includes amechanical latch 21572. Thelatch 21572 is mounted to the frame of thesuture assembly 21530 at theframe pivot 21232. Thelatch 21572 extends distally and is supported by frame pins 21533. Thelatch 21572 includes wire; however, thelatch 21572 may be constructed of any suitable material. Thelatch 21572 also includes anelongated recess track 21576 defined in the latch that is configured to receive alatch pin 21166 extending from the firingmember 21160. Referring primarily to FIG. 35, the elongated recess track 21276 constrains or limits longitudinal displacement of the firingmember 21160 when thelatch 21572 is in its locked position. More specifically, the recessedtrack 21576 is configured to permit distal advancement of the firingmember 21160 to move theanvil clamp 21540 between its open and closed positions, but prevent distal advancement of the firingmember 21160 to execute the firing stroke, Unless thelatch 21572 is moved to its unlocked position, as described below.

当钉仓夹具21550附接到缝合组件21530时，如图36所示，仓夹具21550的滑动件21270接触闭锁件21572的远侧臂21574并使闭锁件21572向下偏转到其解锁位置。此时，闭锁件21572已经位移到击发构件21160的闭锁销21166下方，并且因此，击发构件21160可以向远侧推进以执行钉击发冲程，如图37所示。在钉击发冲程期间，击发构件21160将滑动件21270向远侧推离闭锁臂21574，并且闭锁件21572可以返回到其未折曲或锁定的构造。当击发构件21160缩回时，如图38所示，闭锁销21166可以与闭锁件21572接合并向下折曲闭锁件21572以准许击发构件21160返回其未击发位置。值得注意的是，滑动件21270没有与击发构件21160一起缩回，并且因此，即使击发构件21160已经缩回也不能重新解锁闭锁件21572。因此，闭锁件21572可以用作缺失的仓闭锁件和用完的仓闭锁件。When thecartridge clamp 21550 is attached to the staplingassembly 21530, as shown in Figure 36, theslider 21270 of thecartridge clamp 21550 contacts thedistal arm 21574 of thelatch 21572 and deflects thelatch 21572 downwardly to its unlocked position. At this point, thelatch 21572 has been displaced below thelatch pin 21166 of the firingmember 21160, and thus, the firingmember 21160 can be advanced distally to perform the staple firing stroke, as shown in FIG. During the staple firing stroke, the firingmember 21160 pushes theslider 21270 distally away from thelatch arm 21574, and thelatch 21572 can return to its undeflexed or locked configuration. When the firingmember 21160 is retracted, as shown in FIG. 38, the latchingpin 21166 can engage and flex the latchingmember 21572 downwardly to permit the firingmember 21160 to return to its unfired position. Notably, theslider 21270 is not retracted with the firingmember 21160, and thus, thelatch 21572 cannot be re-unlocked even if the firingmember 21160 has been retracted. Thus, thelatch 21572 can function as a missing bin latch and a spent bin latch.

现在转向图39至图43，缝合组件21330包括可附接的钉仓夹具21350，其包括仓主体21351，以及另外的砧座夹具21340。缝合组件21330还包括击发构件，例如诸如击发构件21160，其能够向远侧移动以接合砧座夹具21340和仓夹具21350。更具体地，击发构件21160包括被构造成接合仓夹具21350的第一凸轮构件21162和被构造成接合砧座夹具21340的第二凸轮构件21164，当击发构件21160向远侧推进时，第一凸轮构件21162和第二凸轮构件21164闭合夹具21340和21350。Turning now to FIGS. 39-43 , the staplingassembly 21330 includes an attachablestaple cartridge clamp 21350 , which includes acartridge body 21351 , and an additional anvil clamp 21340 . The staplingassembly 21330 also includes a firing member, such as, for example, a firingmember 21160 that can be moved distally to engage the anvil clamp 21340 and thecartridge clamp 21350. More specifically, the firingmember 21160 includes afirst cam member 21162 configured to engage thecartridge clamp 21350 and asecond cam member 21164 configured to engage the anvil clamp 21340, thefirst cam member 21164 configured to engage the anvil clamp 21340 when the firingmember 21160 is advanced distally.Member 21162 andsecond cam member 21164close clamps 21340 and 21350.

缝合组件21330还包括机械闭锁件21372。闭锁件21372在框架枢轴21232处安装到缝合组件21330的框架。闭锁件21372向远侧延伸并受到框架销21333的约束。闭锁件21372包括金属线；然而，闭锁件21372可以由任何合适的材料构成。闭锁件21372还包括限定在闭锁件中的细长凹陷部轨道21376，其被构造成接收从击发构件21160延伸的闭锁销21166。主要参考图39，当闭锁件21372处于其锁定位置时，细长凹陷部轨道21376约束或限制击发构件21160的纵向位移。更具体地，凹陷部轨道21376被构造成准许击发构件21160向远侧推进以闭合缝合组件21330但是防止击发构件21160向远侧推进以执行击发冲程。Thesuturing assembly 21330 also includes amechanical latch 21372. Thelatch 21372 is mounted to the frame of thesuture assembly 21330 at theframe pivot 21232. Thelatch 21372 extends distally and is constrained by frame pins 21333. Thelatch 21372 includes wire; however, thelatch 21372 may be constructed of any suitable material. Thelatch 21372 also includes anelongated recess track 21376 defined in the latch that is configured to receive alatch pin 21166 extending from the firingmember 21160. Referring primarily to FIG. 39, theelongated recess track 21376 constrains or limits longitudinal displacement of the firingmember 21160 when thelatch 21372 is in its locked position. More specifically, the recessedtrack 21376 is configured to permit distal advancement of the firingmember 21160 to close the staplingassembly 21330 but prevent distal advancement of the firingmember 21160 to perform the firing stroke.

当钉仓夹具21550附接到缝合组件21530时，如图40所示，钉仓21350的滑动件21370接触闭锁件21372的远侧臂21374并使闭锁件21372向上偏转到解锁位置。在这一点上，闭锁件21372已经在击发构件21160的闭锁销21166上方位移，并且因此，击发构件21160可以向远侧推进以执行钉击发冲程，如图41所示。在钉击发冲程期间，击发构件21160将滑动件21370从闭锁臂21374下方向远侧推出，并且闭锁件21372可以返回到其未折曲或锁定构造。当击发构件21160缩回时，如图42所示，闭锁销21166可以接合闭锁件21372并向上折曲闭锁件21372以准许击发构件21160返回其未击发位置。值得注意的是，滑动件21370不与击发构件21160一起返回。因此，闭锁件21372可以用作缺失的仓闭锁件和用完的仓闭锁件。When thestaple cartridge clamp 21550 is attached to the staplingassembly 21530, as shown in Figure 40, theslider 21370 of thestaple cartridge 21350 contacts thedistal arm 21374 of thelatch 21372 and deflects thelatch 21372 upwardly to the unlocked position. At this point, thelatch 21372 has been displaced over thelatch pin 21166 of the firingmember 21160, and thus, the firingmember 21160 can be advanced distally to perform the staple firing stroke, as shown in FIG. 41 . During the staple firing stroke, the firingmember 21160 pushes theslider 21370 distally from under thelatch arm 21374, and thelatch 21372 can return to its undeflexed or locked configuration. When the firingmember 21160 is retracted, as shown in FIG. 42 , the latchingpin 21166 can engage the latchingmember 21372 and flex the latchingmember 21372 upwardly to permit the firingmember 21160 to return to its unfired position. Notably, theslider 21370 does not return with the firingmember 21160. Thus, thelatch 21372 can be used as a missing bin latch and a spent bin latch.

参考图43，闭锁件21372的臂21374在纵向狭槽21359的相对侧上侧向间隔开，使得击发构件21160可以在臂21374之间滑动。在此类情况下，臂不被击发构件21160横切。43, thearms 21374 of thelatch 21372 are spaced laterally on opposite sides of thelongitudinal slot 21359 so that the firingmember 21160 can slide between thearms 21374. In such cases, the arms are not transversed by the firingmember 21160.

在外科手术期间，几个装载单元可以与外科缝合系统的柄部一起使用。在至少一种情况下，例如，可以使用第一装载单元，其被构造成应用30mm的钉线，可以使用第二装载单元，其被构造成应用45mm的钉线，并且可以使用第三装载单元，其被构造成应用60mm的钉线。在这些装载单元中的每个包括可替换的仓夹具的情况下，错误的钉仓夹具可以附接到装载单元的情况是有可能的。比如，临床医生可尝试将60mm钉仓夹具附接到被构造成应用30mm钉线的装载单元。因此，从60mm钉仓夹具射出的钉中的一些可能不会被砧座变形和/或组织切口线可能比钉线更长的情况是有可能的。本文所公开的缝合组件和/或装载单元可以包括用于防止错误的钉仓夹具附接到其上的装置，如下面更详细地讨论的。During surgery, several loading units can be used with the handle of the surgical stapling system. In at least one case, for example, a first loading unit can be used that is configured to apply a 30mm staple line, a second loading unit can be used that is configured to apply a 45 mm staple line, and a third loading unit can be used , which is configured to apply a 60mm staple line. Where each of these loading units includes a replaceable cartridge clamp, it is possible that the wrong cartridge clamp may be attached to the loading unit. For example, a clinician may attempt to attach a 60mm staple cartridge clamp to a loading unit configured to apply a 30mm staple wire. Thus, it is possible that some of the staples fired from the 60mm staple cartridge jig may not be deformed by the anvil and/or the tissue incision line may be longer than the staple line. The stapling assemblies and/or loading units disclosed herein may include means for preventing incorrect cartridge clamps from being attached thereto, as discussed in more detail below.

参考图44和图46，除上述之外，限定在仓夹具21250中的凹陷部21052被构造成紧密地接收装载单元21130的附接突出部21142，使得在它们之间存在紧密配合。在至少一种情况下，第二装载单元21242’的附接突出部21242’(图45)小于附接突出部21142，并且对应地，用于与第二装载单元21242’一起使用的第二仓夹具的凹陷部小于凹陷部21052。为了提供错误校对形式，第二仓夹具的凹陷部太小而不能接收装载单元21130的附接突出部21142，因此，第二仓夹具不能附接到装载单元21130。类似地，现在转向图45，仓夹具21250的凹陷部21052大于第二装载单元21130’的附接突出部21242’，使得仓夹具21250的夹子21056不能将附接突出部21242’保持在第二装载单元21130’中。因此，不能将仓夹具21250保持在装载单元21130’上。在此类情况下，仓夹具21250和装载单元21130’之间的互连对于仓夹具21250而言太松而不能与装载单元21130’一起使用。44 and 46, in addition to the above, therecesses 21052 defined in themagazine clamp 21250 are configured to closely receive theattachment protrusions 21142 of theloading unit 21130 such that there is a tight fit therebetween. In at least one instance, the attachment tab 21242' (FIG. 45) of the second loading unit 21242' is smaller than theattachment tab 21142 and, correspondingly, the second bin for use with the second loading unit 21242' The recessed portion of the clamp is smaller than the recessedportion 21052 . In order to provide a form of error proofing, the recess of the second bin clamp is too small to receive theattachment protrusions 21142 of theloading unit 21130, and therefore, the second magazine clamp cannot be attached to theloading unit 21130. Similarly, turning now to FIG. 45, therecess 21052 of thebin clamp 21250 is larger than the attachment protrusion 21242' of the second loading unit 21130', so that theclip 21056 of thebin clamp 21250 cannot hold the attachment protrusion 21242' in the second loading unit unit 21130'. Therefore, themagazine clamp 21250 cannot be held on the loading unit 21130'. In such a case, the interconnection between themagazine clamp 21250 and the loading unit 21130' is too loose for themagazine clamp 21250 to be used with the loading unit 21130'.

在上述情况下，装载单元的附接突出部、钉仓夹具的凹陷部和将钉仓夹具保持到装载单元的弹簧夹子在缝合组件的两侧上具有相同的构造。在其它情况下，在缝合组件的一侧上的附接突出部、凹陷部和/或弹簧夹子不同于在缝合组件的另一侧上的附接突出部、凹陷部和/或弹簧夹子。例如，大的附接突出部、凹陷部和弹簧夹子设置在缝合组件的一侧上，而较小的附接突出部、凹陷部和弹簧夹子设置在另一侧上。此类布置可以增加可用的排列，以防止不正确的钉仓夹具附接到装载单元。In the above case, the attachment protrusions of the loading unit, the recesses of the cartridge clamps, and the spring clips holding the cartridge clamps to the loading unit have the same configuration on both sides of the suturing assembly. In other cases, the attachment protrusions, recesses and/or spring clips on one side of the suturing assembly are different from the attachment protrusions, recesses and/or spring clips on the other side of the suturing assembly. For example, large attachment protrusions, recesses and spring clips are provided on one side of the suture assembly, while smaller attachment protrusions, recesses and spring clips are provided on the other side. Such an arrangement may increase the available arrangement to prevent incorrect cartridge clamps from being attached to the loading unit.

在上述情况下，装载单元的附接突出部、钉仓夹具的凹陷部和弹簧夹子相对于共同的侧向轴线对准。在其它情况下，在缝合组件的一侧上的附接突出部、凹陷部和/或弹簧夹子不与另一侧上的突出部、凹陷部和/或弹簧夹子对准。换句话说，一侧偏离另一侧。此类布置还可以增加可用的排列，以防止不正确的钉仓夹具附接到装载单元。In the above case, the attachment protrusions of the loading unit, the recesses of the cartridge clamps and the spring clips are aligned with respect to a common lateral axis. In other cases, the attachment tabs, recesses and/or spring clips on one side of the suture assembly are not aligned with the tabs, recesses and/or spring clips on the other side. In other words, one side is offset from the other. Such an arrangement may also increase the available permutations to prevent incorrect cartridge clamps from being attached to the loading unit.

除上述之外，预期可以提供装载单元的套件，其中套件的每个装载单元可以被构造成使得仅旨在与装载单元一起使用的仓夹具可以正确地附接到装载单元。In addition to the above, it is contemplated that a kit of loading units may be provided, wherein each loading unit of the kit may be configured such that only magazine clamps intended for use with the loading unit may be properly attached to the loading unit.

现在转到图47和图48，钉仓夹具21050包括近侧肩部21058，当仓夹具21050附接到装载单元21030时，近侧肩部21058定位成靠近装载单元21030的框架。例如，由于突出部21042、凹陷部21052和夹子21056之间的紧密配合，仓夹具21050被保持就位，使得仓夹具21050的肩部21058不中断击发构件21160向远侧前进。更具体地，肩部21058不中断击发构件21160的第一凸轮构件21162。在将不正确的钉仓附接到仓夹具21050的情况下，在某些情况下，不正确的仓夹具的近侧肩部可中断第一凸轮构件的远侧前进，并且因此防止击发构件21160用不正确的钉仓执行击发冲程。现在转向图49，钉仓夹具21450是与装载单元21030一起使用的不正确的钉仓夹具。尽管钉仓夹具21450已经附接到装载单元21030，但是近侧肩部21458防止击发构件21060向远侧推进。Turning now to FIGS. 47 and 48 , thecartridge clamp 21050 includes aproximal shoulder 21058 that is positioned proximate the frame of theloading unit 21030 when thecartridge clamp 21050 is attached to theloading unit 21030 . For example, due to the tight fit between theprotrusions 21042, therecesses 21052, and theclips 21056, thecartridge clamp 21050 is held in place such that theshoulders 21058 of thecartridge clamp 21050 do not interrupt the distal advancement of the firingmember 21160. More specifically, theshoulder 21058 does not interrupt thefirst cam member 21162 of the firingmember 21160. In the event that an incorrect staple cartridge is attached to thecartridge clamp 21050, in some cases the proximal shoulder of the incorrect cartridge clamp can interrupt the distal advancement of the first cam member and thus prevent the firingmember 21160 Execution of firing stroke with incorrect cartridge. Turning now to FIG. 49 ,cartridge clamp 21450 is an incorrect cartridge clamp used withloading unit 21030. Although thecartridge clamp 21450 has been attached to theloading unit 21030, theproximal shoulder 21458 prevents distal advancement of the firing member 21060.

除上述之外，钉仓夹具的近侧肩部可以包括尖锐或突兀的拐角。在至少一个此种情况下，近侧肩部例如不包括倒角或引入端。In addition to the above, the proximal shoulder of the cartridge clamp may include sharp or sharp corners. In at least one such instance, the proximal shoulder, for example, does not include a chamfer or lead-in.

在各种情况下，钉仓夹具的近侧肩部可以被构造成如果夹紧在钉仓夹具和相对的砧座夹具之间的组织太厚则阻挡钉击发构件向远侧推进。在此类情况下，钉仓夹具将不会完全闭合，并且钉仓夹具的近侧肩部将定位在钉击发构件的前方。此种布置将包括组织厚度闭锁件；然而，在钉仓夹具还没有移动到其夹紧位置的情况下，此种布置也可以用作组织夹紧闭锁件。In various cases, the proximal shoulder of the cartridge clamp can be configured to block distal advancement of the staple firing member if the tissue clamped between the cartridge clamp and the opposing anvil clamp is too thick. In such a case, the cartridge clamp would not be fully closed and the proximal shoulder of the cartridge clamp would be positioned in front of the staple firing member. Such an arrangement would include a tissue thickness lockout; however, this arrangement could also function as a tissue clamping lockout without the cartridge clamp being moved to its clamping position.

除了上述之外或代替上述内容，可以利用外科器械系统的电子或软件闭锁件来防止在不正确的钉仓夹具附接到外科器械系统的情况下击发驱动器执行钉击发冲程。在各种情况下，如上所述，夹具检测电路的一部分可以延伸通过钉仓夹具，并且在至少一种情况下，外科器械系统的控制器可以被构造成评估延伸通过钉仓夹具的夹具检测电路的部分，以确定附接到外科器械系统的钉仓夹具是否是与外科器械系统一起使用的合适的钉仓夹具。在至少一种情况下，第一钉仓夹具的夹子21056具有例如与第二钉仓夹具的夹子21056可检测地不同的电特性，诸如电阻或阻抗。In addition to or in lieu of the above, an electronic or software latch of the surgical instrument system may be utilized to prevent the firing driver from performing the staple firing stroke if an incorrect cartridge clamp is attached to the surgical instrument system. In various cases, as described above, a portion of the clip detection circuit can extend through the cartridge clip, and in at least one case, the controller of the surgical instrument system can be configured to evaluate the clip detection circuit extending through the cartridge clip section to determine whether a cartridge holder attached to a surgical instrument system is a suitable cartridge holder for use with the surgical instrument system. In at least one instance, theclip 21056 of the first cartridge clip has, for example, a detectably different electrical characteristic, such as resistance or impedance, than theclip 21056 of the second cartridge clip.

再次参考图22、图26和图28，仓夹具移除工具21090可以用于将仓夹具从装载单元拆卸。美国专利申请公布号2012/0286021更详细地讨论了仓移除工具。美国专利申请公布号2012/0286021更详细地讨论了仓移除工具。Referring again to Figures 22, 26, and 28, a magazineclamp removal tool 21090 can be used to remove the magazine clamp from the loading unit. US Patent Application Publication No. 2012/0286021 discusses the bin removal tool in more detail. US Patent Application Publication No. 2012/0286021 discusses the bin removal tool in more detail.

期望采用具有外科缝合器械(其具有可替换钉仓组件)的闭锁系统。例如，在使用者忘记将钉仓安装到没有此种闭锁系统的器械中的情况下，外科器械的击发构件可用于切割患者的组织而不将其缝合。此类情况是不期望的。在又一个示例中，在使用者将用完的或部分用完的钉仓安装到器械中并且没有闭锁系统的情况下，外科器械的击发构件将类似地切割但不缝合，或仅部分缝合患者的组织。此类情况也是不期望的。因此，期望可以自动闭锁击发构件以防止击发构件在端部执行器内被推进的外科器械。It is desirable to employ a lockout system with a surgical stapling instrument with a replaceable cartridge assembly. For example, the firing member of a surgical instrument can be used to cut a patient's tissue without stapling it in the event a user forgets to install a staple cartridge into an instrument that does not have such a latching system. Such a situation is not desired. In yet another example, where the user installs a spent or partially spent staple cartridge into the instrument and there is no latching system, the firing member of the surgical instrument will similarly cut but not sut, or only partially sut the patient organization. Such a situation is also undesirable. Accordingly, a surgical instrument that can automatically lock the firing member to prevent the firing member from being advanced within the end effector is desired.

现在转到图50和图51，示出了包括缺失的仓和用完的仓闭锁系统的外科器械系统25100。系统25100包括击发构件25110、钉仓组件25120和砧座夹具25130。击发构件25110包括远侧呈现的切割部分25111，当被推进通过外科器械系统25100的端部执行器部分时，切割部分被构造成切割组织。击发构件25110被构造成通过将滑动件25121纵向推进通过钉仓组件25120而将多个钉从钉仓组件25120朝向砧座夹具25130部署。在钉击发冲程期间，滑动件25121能够从近侧未击发位置移动到远侧完全击发位置。在钉击发冲程完成之后，击发构件25110缩回。滑动件25121不与击发构件25110缩回。然而，设想了其中滑动件25121至少部分缩回的实施方案。Turning now to FIGS. 50 and 51, asurgical instrument system 25100 is shown including a missing cartridge and a spent cartridge latching system.System 25100 includes firingmember 25110,cartridge assembly 25120, andanvil clamp 25130. The firingmember 25110 includes a distally presented cuttingportion 25111 configured to cut tissue when advanced through the end effector portion of thesurgical instrument system 25100. The firingmember 25110 is configured to deploy a plurality of staples from thestaple cartridge assembly 25120 toward theanvil clamp 25130 by advancing theslider 25121 longitudinally through thestaple cartridge assembly 25120. During the staple firing stroke, theslider 25121 can be moved from a proximal unfired position to a distal fully fired position. After the staple firing stroke is complete, the firingmember 25110 is retracted.Slider 25121 does not retract with firingmember 25110. However, embodiments in which theslider 25121 is at least partially retracted are contemplated.

外科器械系统25100还包括闭锁构件25140。当外科器械系统25100中不存在仓或外科器械系统25100中存在用完的或部分用完的仓时，闭锁构件25140被构造成防止击发构件25110被推进通过钉击发冲程。闭锁构件25140包括近侧部分25141，该近侧部分25141可枢转地安装到系统25100的框架部分的脊柱销25101。闭锁构件25140还包括锁定面或肩部25142(其构造成卡扣击发构件25110)，以及可偏转部分25143。当钉仓组件安装在系统25100内时，闭锁构件25140能够在锁定位置(图50)和解锁位置(图51)之间移动或偏转。当钉仓组件未安装在系统25100内时，闭锁构件25140被弹簧偏压到锁定位置，如下面更详细地讨论的。当用完的或部分用完的钉仓组件安装在系统25100内时，闭锁构件25140也弹簧偏压到锁定位置，如下面更详细地讨论的。Surgical instrument system 25100 also includes a latchingmember 25140. The blockingmember 25140 is configured to prevent the firingmember 25110 from being advanced through the staple firing stroke when no or a spent or partially spent cartridge is present in thesurgical instrument system 25100. The blockingmember 25140 includes aproximal portion 25141 that is pivotally mounted to thespinal pin 25101 of the frame portion of thesystem 25100. The blockingmember 25140 also includes a locking surface or shoulder 25142 (which is configured to snap into the firing member 25110 ), and adeflectable portion 25143 . When the cartridge assembly is installed within thesystem 25100, the latchingmember 25140 can move or deflect between a locked position (FIG. 50) and an unlocked position (FIG. 51). When the cartridge assembly is not installed within thesystem 25100, the latchingmember 25140 is spring biased to the locked position, as discussed in more detail below. The latchingmember 25140 is also spring biased to the locked position when a spent or partially spent cartridge assembly is installed within thesystem 25100, as discussed in more detail below.

当闭锁构件25140处于其锁定位置时，如图50所示，安装在击发构件25110上的击发构件销25113被构造成邻接闭锁构件25140的锁定面25142，其防止击发构件25110向远侧推进。为了将闭锁构件25140从锁定位置移动到解锁位置，必须将未用完的，准备好击发的钉仓组件正确地安装在系统25100内。更具体地，未用完的，准备好击发的钉仓组件的滑动件25121处于其近侧未击发位置，并且当此种钉仓组件安装到系统25100中时，滑动件25121使可偏转部分25143向下偏转或弯曲进入其解锁位置。当闭锁构件25140处于其解锁位置时，参考图51，击发构件销25113清楚地推进超过锁定面25142，从而允许击发构件25110向远侧推进以在击发冲程期间部署钉并且切割组织。When the blockingmember 25140 is in its locked position, as shown in FIG. 50, the firingmember pin 25113 mounted on the firingmember 25110 is configured to abut the lockingsurface 25142 of the blockingmember 25140, which prevents distal advancement of the firingmember 25110. In order to move the latchingmember 25140 from the locked position to the unlocked position, the unused, ready-to-fire staple cartridge assembly must be properly installed within thesystem 25100. More specifically, thesled 25121 of an unused, ready-to-fire staple cartridge assembly is in its proximal unfired position, and when such a staple cartridge assembly is installed in thesystem 25100, thesled 25121 causes thedeflectable portion 25143 Deflects or bends down into its unlocked position. When the blockingmember 25140 is in its unlocked position, referring to Figure 51, the firingmember pin 25113 is clearly advanced beyond the lockingsurface 25142, allowing the firingmember 25110 to be advanced distally to deploy the staples and cut tissue during the firing stroke.

如在图50和图51中可以看到的，当闭锁构件25140处于其锁定位置时，准许击发构件25110的一些纵向移动。当闭锁构件25140处于其锁定位置时，这种纵向移动自由度允许击发构件25110向远侧推进以闭合系统25100的夹具并向近侧移动以防止夹具重新打开。例如，操纵系统25100的夹具对于装载和/或卸载钉仓可能是必需的。As can be seen in Figures 50 and 51, some longitudinal movement of the firingmember 25110 is permitted when the blockingmember 25140 is in its locked position. When the blockingmember 25140 is in its locked position, this freedom of longitudinal movement allows the firingmember 25110 to be advanced distally to close the clips of thesystem 25100 and moved proximally to prevent the clips from reopening. For example, a gripper of themanipulation system 25100 may be necessary to load and/or unload a staple cartridge.

如上所述，当击发构件25110在击发冲程之后缩回时，滑动件25121不与击发构件25110一起返回。当击发构件25110缩回时，击发构件销25113使可偏转部分25143偏转或弯曲到其解锁位置，从而准许销25113穿过锁定面25142并返回到原始位置。一旦销25113缩回穿过锁定面25142，闭锁构件25140就弹回或返回到其锁定位置，以防止用安装在系统25100内的用完的钉仓重复击发。击发构件25110可以进一步缩回，使得系统25100的夹具然后可以从缝合组织松开。As described above, theslider 25121 does not return with the firingmember 25110 when the firingmember 25110 is retracted after the firing stroke. When the firingmember 25110 is retracted, the firingmember pin 25113 deflects or bends thedeflectable portion 25143 to its unlocked position, permitting thepin 25113 to pass through the lockingsurface 25142 and return to the original position. Once thepin 25113 is retracted through the lockingface 25142, the latchingmember 25140 springs or returns to its locked position to prevent repeated firing with a spent cartridge installed within thesystem 25100. The firingmember 25110 can be retracted further so that the clamps of thesystem 25100 can then be released from the stapled tissue.

现在参考图52至图54，示出了另一种外科器械系统25200。系统25200包括另一种类型的缺失仓和用完的仓闭锁件布置。系统25200包括击发构件25210和钉仓组件25220。击发构件25210包括远侧呈现的切割部分25211，其被构造成在被推进通过系统25200时切割组织。击发构件被构造成通过将滑动件25221纵向推进穿过钉仓组件25220而从钉仓组件25220部署多个钉。在钉击发冲程期间，滑动件25221能够从近侧未击发位置移动到远侧完全击发位置。滑动件25221不与击发构件25210一起缩回；然而，设想了其中滑动件25221至少部分缩回的实施方案。Referring now to Figures 52-54, anothersurgical instrument system 25200 is shown.System 25200 includes another type of missing cartridge and spent cartridge latch arrangement.System 25200 includes firingmember 25210 andcartridge assembly 25220. The firingmember 25210 includes a distally presented cuttingportion 25211 configured to cut tissue when advanced through thesystem 25200. The firing member is configured to deploy the plurality of staples from thestaple cartridge assembly 25220 by advancing theslider 25221 longitudinally through thestaple cartridge assembly 25220. During the staple firing stroke, theslider 25221 can be moved from a proximal unfired position to a distal fully fired position. Theslider 25221 is not retracted with the firingmember 25210; however, embodiments in which theslider 25221 is at least partially retracted are contemplated.

外科器械系统25200还包括闭锁构件25240。当系统25200内不存在仓或系统25200内存在用完的或部分用完的仓时，闭锁构件25240被构造成防止击发构件25210被推进通过其钉击发冲程。闭锁构件25240包括可旋转地安装到系统25200的第一脊柱销25201的第一或近侧部分25241。例如，脊柱销25201可从系统25200的轴框架或脊柱延伸。闭锁构件25240还包括第二部分25242、第三或卡扣部分25243，以及第四或远侧部分25245。闭锁构件25240能够在锁定位置(图52和图54)和解锁位置(图53)之间移动。当钉仓组件未正确地安装在系统25200内时，闭锁构件25240被弹簧偏压到锁定位置。当用完的或部分用完的钉仓组件安装在系统25200内时，闭锁构件25240也被偏压到锁定位置。Surgical instrument system 25200 also includes a latching member 25240. The blocking member 25240 is configured to prevent the firingmember 25210 from being advanced through its staple firing stroke when no cartridge is present within thesystem 25200 or a spent or partially spent cartridge is present within thesystem 25200. The blocking member 25240 includes a first orproximal portion 25241 that is rotatably mounted to the firstspinal pin 25201 of thesystem 25200. For example, spine pins 25201 may extend from the shaft frame or spine ofsystem 25200. The latching member 25240 also includes asecond portion 25242, a third orsnap portion 25243, and a fourth ordistal portion 25245. The latching member 25240 is movable between a locked position (FIGS. 52 and 54) and an unlocked position (FIG. 53). When the cartridge assembly is not properly installed within thesystem 25200, the latching member 25240 is spring biased to the locked position. The latching member 25240 is also biased to the locked position when a spent or partially spent cartridge assembly is installed within thesystem 25200.

当闭锁构件25240处于其锁定位置时，如图52所示，安装在击发构件25210上的击发构件销25213被构造成邻接闭锁构件25240的锁定面或肩部25244。由于锁定面25244，阻挡击发构件25210向远侧推进超过该位置。为了将闭锁构件25240从其锁定位置移动到其解锁位置，必须在系统25200内安装未用完的，准备好击发的钉仓组件。未用完的，准备好击发的钉仓组件包括处于近侧未击发位置的滑动件25221。When the blocking member 25240 is in its locked position, as shown in FIG. Due to thelocking surface 25244, distal advancement of the firingmember 25210 beyond this position is blocked. In order to move the latching member 25240 from its locked position to its unlocked position, an unused, ready-to-fire staple cartridge assembly must be installed within thesystem 25200. The unused, ready-to-fire staple cartridge assembly includesslider 25221 in a proximal unfired position.

滑动件25221包括磁体25226，该磁体25226的一个极“P1”面向闭锁构件25240的远侧部分25245，另一个极“P2”远离闭锁构件25240的远侧部分25245。闭锁构件25240的远侧部分25245包括设置在其上的磁体25246。磁体25246取向成极“P1”面向滑动件磁体25226的相同的极“P1”，并且另一个极“P2”远离滑动件磁体25226。磁体25226的极P1和磁体25246的极P1彼此排斥。当滑动件25221处于其近侧未击发位置(图53)时，这种关系产生悬浮效应，其将闭锁构件25240向上推动或排斥到其解锁位置，从而将锁定面25244提升离开击发构件25210的销25213，以准许销25213推进超过锁定面25142。然后可以将击发构件25210向远侧推进以在击发冲程期间部署钉并且切割组织。Theslider 25221 includes amagnet 25226 with one pole "P1" facing thedistal portion 25245 of the blocking member 25240 and the other pole "P2" facing away from thedistal portion 25245 of the blocking member 25240. Thedistal portion 25245 of the blocking member 25240 includes amagnet 25246 disposed thereon. Themagnet 25246 is oriented with pole "P1" facing the same pole "P1" of theslider magnet 25226 and the other pole "P2" away from theslider magnet 25226. Pole P1 ofmagnet 25226 and pole P1 ofmagnet 25246 repel each other. When theslider 25221 is in its proximal unfired position (FIG. 53), this relationship creates a levitating effect that pushes or repels the blocking member 25240 up to its unlocked position, thereby lifting the lockingface 25244 away from the pin of the firingmember 25210 25213 to allow thepin 25213 to advance beyond the lockingsurface 25142. The firingmember 25210 can then be advanced distally to deploy the staples and cut tissue during the firing stroke.

当击发构件25210在其击发冲程之后缩回时，销25213被构造成接触远侧部分25245的倾斜面以将远侧部分25245并因此将闭锁构件25240朝向其解锁位置推动，从而准许销25213在返回到原始位置时穿过锁定面25244。一旦销25213穿过锁定面25244，闭锁构件25240就弹回或返回到其锁定位置，以防止用安装在系统25100内的用完的或部分用完的钉仓重复击发冲程。When the firingmember 25210 is retracted after its firing stroke, thepin 25213 is configured to contact the sloped surface of thedistal portion 25245 to urge thedistal portion 25245 and thus the blocking member 25240 toward its unlocked position, thereby permitting thepin 25213 to return to the Pass through lockingsurface 25244 when in home position. Once thepin 25213 passes through the lockingsurface 25244, the latching member 25240 springs or returns to its locked position to prevent repeated firing strokes with a spent or partially spent staple cartridge installed within thesystem 25100.

类似于图50和图51中所示的系统25100，闭锁构件25240被构造成准许击发构件25210在距离“y”内移动，以准许当击发构件25210被用于夹紧和松开功能时夹紧和松开夹具。销25213以及因此击发构件25210可以在闭锁构件25240的卡扣部分25243内向近侧和向远侧移动，即使钉仓从系统25100缺失和/或用完的钉仓定位在系统25100内。Similar to thesystem 25100 shown in Figures 50 and 51, the blocking member 25240 is configured to permit movement of the firingmember 25210 within a distance "y" to permit clamping when the firingmember 25210 is used for clamping and unclamping functions and release the clamp. Thepin 25213 and thus the firingmember 25210 can move proximally and distally within thesnap portion 25243 of the latching member 25240, even if a staple cartridge is missing from thesystem 25100 and/or a spent staple cartridge is positioned within thesystem 25100.

图55至图60中示出了另一个外科器械系统25300。系统25300包括另一种类型的闭锁件布置，其中当仓未安装在系统25300内时，系统25300被构造成被闭锁。当在系统25300内安装用完或部分用完的仓时，该系统还被构造成被闭锁。系统25300包括击发构件25310和钉仓组件25320。击发构件25310包括远侧呈现的切割部分25311，该切割部分25311被构造成在推进通过系统25300时切割组织。击发构件25310被构造成通过推进滑动件25330(图56)纵向通过钉仓组件25320而从钉仓组件25320部署多个钉。在击发冲程期间，滑动件25330能够在近侧未击发位置和远侧完全击发位置之间移动。在各种情况下，滑动件25230不会与击发构件25310一起缩回；然而，设想了其中滑动件25230至少部分缩回的实施方案。Anothersurgical instrument system 25300 is shown in FIGS. 55-60.System 25300 includes another type of latch arrangement in whichsystem 25300 is configured to be latched when a cartridge is not installed withinsystem 25300. The system is also configured to be latched when a spent or partially spent cartridge is installed within thesystem 25300.System 25300 includes firingmember 25310 andcartridge assembly 25320. The firingmember 25310 includes a distally presented cuttingportion 25311 configured to cut tissue when advanced through thesystem 25300. The firingmember 25310 is configured to deploy a plurality of staples from thestaple cartridge assembly 25320 by advancing the slider 25330 (FIG. 56) longitudinally through thestaple cartridge assembly 25320. During the firing stroke, theslider 25330 can be moved between a proximal unfired position and a distal fully fired position. In various instances, the slider 25230 is not retracted with the firingmember 25310; however, embodiments in which the slider 25230 is at least partially retracted are contemplated.

外科器械系统25300还包括闭锁构件25340。当系统25300内不存在仓或系统25300内存在用完或部分用完的仓时，闭锁构件25340被构造成防止击发构件25310被推进通过钉击发冲程。闭锁构件25340在许多方面类似于闭锁构件25140、25240。参考图58至图60，闭锁构件25340包括可旋转地安装到系统25300的第一脊柱销25301的第一或近侧部分25341。另选地，近侧部分25341可以固定地安装到系统25300的脊柱25301。闭锁构件25340还包括第二部分25342、第三或卡扣部分25343，以及第四或远侧部分25345。闭锁构件25340能够在锁定位置(图58和图60)和解锁位置(图59)之间移动。当钉仓组件未安装在系统25300内时，闭锁构件25340被弹簧偏压到其锁定位置。当用完的或部分用完的钉仓组件安装在系统25300内时，闭锁构件25340也被偏压到其锁定位置。Surgical instrument system 25300 also includes a latchingmember 25340. The latchingmember 25340 is configured to prevent the firingmember 25310 from being advanced through the staple firing stroke when no cartridge is present within thesystem 25300 or a spent or partially spent cartridge is present within thesystem 25300. The latchingmember 25340 is similar in many respects to the latchingmembers 25140, 25240. 58-60, the latchingmember 25340 includes a first orproximal portion 25341 of the firstspinal pin 25301 rotatably mounted to thesystem 25300. Alternatively, theproximal portion 25341 may be fixedly mounted to thespine 25301 of thesystem 25300. The blockingmember 25340 also includes asecond portion 25342, a third orsnap portion 25343, and a fourth ordistal portion 25345. The latchingmember 25340 is movable between a locked position (FIGS. 58 and 60) and an unlocked position (FIG. 59). When the cartridge assembly is not installed within thesystem 25300, the latchingmember 25340 is spring biased to its locked position. The latchingmember 25340 is also biased into its locked position when a spent or partially spent cartridge assembly is installed within thesystem 25300.

钉仓组件25320包括滑动件25330和多个驱动器25328，该驱动器25328被构造成在钉击发冲程期间在由滑动件25330的斜面25330A、25330B、25330C和25330D驱动时射出钉。钉仓组件25320还包括控制构件，当滑动件25330在其钉击发冲程期间向远侧推进时，该控制构件能够通过滑动件25330在未用完位置和用完位置之间移动。当钉仓25320被装载到外科器械系统25300中时控制构件处于其未用完位置，并且当未用完的钉仓组件25320被装载到外科器械系统25300中时，控制构件被构造成将闭锁构件25340从其锁定位置移动到其解锁位置。近侧驱动器25325的第一构造在图55和图57中示出。近侧驱动器25325包括驱动器楔形部分25326和磁性部分25327。当近侧驱动器25325处于其未用完位置并且滑动件25330处于其未击发位置时(图59)，驱动器楔形部分25326定位在滑动凹口25331内并且磁性部分25327足够靠近远侧部分25327以吸引远侧部分25327以将闭锁构件25340移动或提升到其解锁位置。Thecartridge assembly 25320 includes asled 25330 and a plurality ofdrivers 25328 configured to fire staples when driven by theramps 25330A, 25330B, 25330C, and 25330D of thesled 25330 during the staple firing stroke. Thestaple cartridge assembly 25320 also includes a control member that can be moved by theslider 25330 between an unused position and a spent position as theslider 25330 is advanced distally during its staple firing stroke. The control member is in its unused position when thestaple cartridge 25320 is loaded into thesurgical instrument system 25300 and is configured to lock the locking member when the unusedstaple cartridge assembly 25320 is loaded into thesurgical instrument system 25300 The 25340 moves from its locked position to its unlocked position. The first configuration of theproximal driver 25325 is shown in FIGS. 55 and 57 . Theproximal driver 25325 includes adriver wedge portion 25326 and amagnetic portion 25327. When theproximal driver 25325 is in its undepleted position and theslider 25330 is in its unfired position (FIG. 59), thedriver wedge portion 25326 is positioned within the slidingnotch 25331 and themagnetic portion 25327 is close enough to thedistal portion 25327 to attract thedistal side portion 25327 to move or lift thelatch member 25340 to its unlocked position.

在图59和图60中示出了类似的近侧驱动器构造。近侧驱动器25325’包括驱动器楔形部分25326’和磁性部分25327’。近侧驱动器25325’的楔形部分25326’位于近侧驱动器25325’的侧面上。当近侧驱动器25325’处于其未用完位置并且滑动件25330处于其未击发位置时(图59)，驱动器楔形部分25326’位于滑动件凹口25331内并且磁性部分25327’足够靠近远侧部分25327’以吸引远侧部分25327’将闭锁构件25340移动到其解锁位置。当驱动器楔形部分25326’位于滑动件凹口25331内时，磁性部分25327’被构造成将闭锁构件25340保持在其解锁位置。当滑动件25330从其未击发位置向远侧推进时，滑动件25330驱动近侧驱动器25325’，使得驱动器楔形部分25326’被驱动脱出滑动件凹口25331。因此，磁性部分25327’不再足够靠近闭锁构件25340以将闭锁构件保持在其解锁位置，因此，闭锁构件被弹簧偏压到其锁定位置(图60)。基准“D”被定义为滑动件25330的顶部表面，并且当楔形部分25326’的底部与基准D对准或在基准D上方时，远侧部分25345和磁性部分25327’之间的磁性关系是不足以将闭锁构件25340保持在其解锁位置，从而释放闭锁构件25340。Similar proximal driver configurations are shown in FIGS. 59 and 60 . The proximal driver 25325' includes a driver wedge portion 25326' and a magnetic portion 25327'. The wedge-shaped portion 25326' of the proximal driver 25325' is located on the side of the proximal driver 25325'. When the proximal driver 25325' is in its unused position and theslider 25330 is in its unfired position (FIG. 59), the driver wedge portion 25326' is located within theslider recess 25331 and the magnetic portion 25327' is sufficiently close to the distal portion 25327 'to attract the distal portion 25327' to move the blockingmember 25340 to its unlocked position. The magnetic portion 25327' is configured to hold the latchingmember 25340 in its unlocked position when the driver wedge portion 25326' is located within theslider recess 25331. As theslider 25330 is advanced distally from its unfired position, theslider 25330 drives the proximal driver 25325' such that the driver wedge portion 25326' Consequently, the magnetic portion 25327' is no longer close enough to the latchingmember 25340 to hold the latching member in its unlocked position, so the latching member is spring biased to its locked position (FIG. 60). Datum "D" is defined as the top surface ofslider 25330, and when the bottom of wedge portion 25326' is aligned with or above datum D, the magnetic relationship betweendistal portion 25345 and magnetic portion 25327' is insufficient to hold the latchingmember 25340 in its unlocked position, thereby releasing the latchingmember 25340.

一旦闭锁构件25340已经释放到其锁定位置(图60)并且已安装的仓组件25320已经至少部分地用完(图60)，则防止系统25300重新击发相同的仓组件25320。当击发构件25310缩回时，闭锁销25312骑在远侧部分下方，以使闭锁构件25340暂时移开，直到闭锁销25312到达卡扣部分25343。当闭锁销25312到达卡扣部分25343时，闭锁构件25340弹回或返回其锁定位置。当处于其用完位置时，磁性部分25327’不会将闭锁构件25340拉入其解锁位置。在各种情况下，当近侧驱动器25325’被滑动件25330移动到其用完位置时，近侧驱动器25325’可以压配合方式接合钉仓组件25320，以防止近侧驱动器25325’朝向其未用完位置下落。此种布置可防止闭锁构件25340被错误地解锁。除了用完的仓组件之外，没有仓安装在系统25300内迫使闭锁构件进入其锁定位置。仅仅没有近侧驱动器完全防止闭锁构件25340移动到其解锁位置。Once the latchingmember 25340 has been released to its locked position (FIG. 60) and the installedcartridge assembly 25320 has been at least partially used up (FIG. 60), thesystem 25300 is prevented from re-firing thesame cartridge assembly 25320. When the firingmember 25310 is retracted, the blockingpin 25312 rides under the distal portion to temporarily move the blockingmember 25340 away until the blockingpin 25312 reaches thesnap portion 25343. When the latchingpin 25312 reaches thecatch portion 25343, the latchingmember 25340 springs back or returns to its latched position. When in its spent position, the magnetic portion 25327' does not pull the latchingmember 25340 into its unlocked position. In various cases, when the proximal driver 25325' is moved to its spent position by theslider 25330, the proximal driver 25325' can engage thecartridge assembly 25320 in a press fit to prevent the proximal driver 25325' from being directed toward its unused position Finished location drop. This arrangement prevents the latchingmember 25340 from being unlocked by mistake. With the exception of a spent cartridge assembly, no cartridge is installed within thesystem 25300 to force the latching member into its locked position. There is only no proximal driver that completely prevents the blockingmember 25340 from moving to its unlocked position.

控制构件25325、25325’由滑动件25330驱动，并且可以被称为驱动器；然而，它们不驱动钉。以这种方式，控制构件25325、25325’包括“假”驱动器。也就是说，可预期钉仓组件的最近侧钉驱动器可以用作控制构件。Thecontrol members 25325, 25325' are driven by theslider 25330 and may be referred to as drivers; however, they do not drive the staples. In this way, thecontrol members 25325, 25325' comprise "dummy" drivers. That is, it is contemplated that the proximal-most staple driver of the staple cartridge assembly may serve as the control member.

另一种外科器械系统在图61至图63中示出。系统25400包括钉仓组件25410、闭锁电路系统25420和闭锁构件25430。闭锁构件25440固定地附接到系统25400的脊柱部分25401。闭锁构件25430还包括例如弹簧构件，并且朝向其锁定位置偏压(图63)。当闭锁构件25430处于其锁定位置时，闭锁构件25430的钩部分25431被构造成在外科器械或临床医生试图将击发构件推进超过闭锁构件25440而没有安装在系统25400内的未用完的钉仓组件的情况下卡扣击发构件。Another surgical instrument system is shown in FIGS. 61-63 .System 25400 includescartridge assembly 25410, latchingcircuitry 25420, and latchingmember 25430. The locking member 25440 is fixedly attached to thespinal portion 25401 of thesystem 25400. The latchingmember 25430 also includes, for example, a spring member, and is biased toward its locked position (FIG. 63). When thelockout member 25430 is in its locked position, thehook portion 25431 of thelockout member 25430 is configured to prevent an unused cartridge assembly from being installed within thesystem 25400 when a surgical instrument or clinician attempts to advance the firing member beyond the lockout member 25440 Snap the firing member in the case.

为了将闭锁构件25440移动到其解锁位置，使得击发构件可以在钉击发冲程期间被推进通过钉仓组件25410，则采用电磁体25421。电磁体25421设置在系统25400的脊柱部分25401上，但是可设置在系统25400内的任何合适的位置处。导体沿脊柱部分25401定位在系统25400内，例如，以给电磁体25421供电。包围电磁体25421及其电源的闭锁电路系统25420延伸通过钉仓组件25410。如下所讨论的，当电路25420接通或闭合时，电磁体25421被供电。当电路未接通或打开时，电磁体25421不通电。还如下面所讨论的，在电路25420打开的情况下，系统25400中存在用完的或部分用完的仓。在电路25420打开的另一种情况下，系统25400中没有仓。To move the latching member 25440 to its unlocked position so that the firing member can be advanced through thestaple cartridge assembly 25410 during the staple firing stroke, anelectromagnet 25421 is employed.Electromagnets 25421 are disposed onspine portion 25401 ofsystem 25400, but may be disposed at any suitable location withinsystem 25400. Conductors are positioned within thesystem 25400 along thespine portion 25401, eg, to power theelectromagnets 25421. Latchingcircuitry 25420 surrounding theelectromagnet 25421 and its power supply extends through thecartridge assembly 25410. As discussed below, theelectromagnet 25421 is powered when thecircuit 25420 is turned on or closed. Theelectromagnet 25421 is not energized when the circuit is not on or open. As also discussed below, withcircuit 25420 open, there is a depleted or partially depleted bin insystem 25400. In the other case wherecircuit 25420 is open, there are no bins insystem 25400.

闭锁电路系统25420包括从电磁体25421延伸到位于系统25400内的一对电接触件25423的导体25422。例如，电接触件25423定位在系统25400的夹具内，诸如接收钉仓组件25410的通道部分。钉仓组件25410还包括导体腿形件25425，当钉仓组件25410完全坐置在夹具的通道部分中时，导体腿形件被构造成接合接触件25423。导体腿形件25425是限定在钉仓组件25410内的电迹线25424的零件。导体腿形件25425设置在仓组件25410的近侧面25412上。同样设置在近侧面25412上的是电迹线25424的可切断部分25426，其延伸越过钉仓组件25410的狭槽25411。击发构件的切割边缘被构造成在击发构件的钉击发冲程期间切断或切入可切断部分25426。Latchingcircuitry 25420 includesconductors 25422 extending fromelectromagnet 25421 to a pair ofelectrical contacts 25423 located withinsystem 25400. For example, theelectrical contacts 25423 are positioned within a fixture of thesystem 25400, such as a channel portion that receives thecartridge assembly 25410. Thecartridge assembly 25410 also includesconductor legs 25425 that are configured to engage thecontacts 25423 when thecartridge assembly 25410 is fully seated in the channel portion of the clamp. Theconductor legs 25425 are part of theelectrical traces 25424 defined within thecartridge assembly 25410.Conductor legs 25425 are disposed onproximal side 25412 ofcartridge assembly 25410. Also disposed onproximal side 25412 is aseverable portion 25426 ofelectrical trace 25424 that extends beyondslot 25411 ofcartridge assembly 25410. The cutting edge of the firing member is configured to sever or cut into theseverable portion 25426 during the staple firing stroke of the firing member.

当安装仓组件并且未用完时，除上述之外，可切断部分25426未被切断并且闭锁电路25420完成或闭合。当闭锁电路25420接通时(图62)，电磁体25421接收电力，迫使闭锁构件25430到其解锁位置，从而准许击发构件穿过。在击发构件的击发冲程期间切断或切割可切断部分25426之后，外科器械检测到未接通的电路。未接通或打开的电路指示钉仓组件25410处于错误构造。这可由于安装了用完或部分用完的仓或没有在系统25400内安装仓。当电路25420未接通时(图63)，例如，在错误构造中，电磁体25421断电并将闭锁构件25430释放到其锁定位置(图63)。When the cartridge assembly is installed and not used up, in addition to the above, thecuttable portion 25426 is not severed and thelatch circuit 25420 is completed or closed. When the latchingcircuit 25420 is on (FIG. 62), theelectromagnet 25421 receives power, forcing the latchingmember 25430 to its unlocked position, permitting the firing member to pass through. After severing or cutting theseverable portion 25426 during the firing stroke of the firing member, the surgical instrument detects an open circuit. A circuit that is not on or open indicates that thecartridge assembly 25410 is in the wrong configuration. This can be due to the installation of a spent or partially used bin or no bin is installed within thesystem 25400. When thecircuit 25420 is not closed (FIG. 63), eg, in an incorrect configuration, theelectromagnet 25421 de-energizes and releases the latchingmember 25430 to its latched position (FIG. 63).

当用完的钉仓组件25410从外科器械系统25400移除时，闭锁电路25420保持在打开状态，并且电磁体25421保持未供电。当未用完的钉仓组件25410完全坐置在系统25400中时，闭锁电路25420再次闭合并且电磁体25421被重新供电以解锁闭锁构件25430。值得注意的是，如果钉仓组件25410未完全坐置在系统25400中，则腿形件25425将不与接触件25423接合，并且闭锁电路25420将保持在打开的未供电状态。When the spentstaple cartridge assembly 25410 is removed from thesurgical instrument system 25400, thelatch circuit 25420 remains open and theelectromagnet 25421 remains unpowered. When theunused cartridge assembly 25410 is fully seated in thesystem 25400, thelatch circuit 25420 is closed again and theelectromagnet 25421 is re-energized to unlock thelatch member 25430. Notably, if thecartridge assembly 25410 is not fully seated in thesystem 25400, thelegs 25425 will not engage thecontacts 25423 and thelatch circuit 25420 will remain in an open, unpowered state.

图64和图65中示出了另一种外科器械系统25500。系统25500包括钉仓25501，该钉仓25501包括能够在未击发位置和击发位置之间移动的滑动件25510。击发构件25503被构造成将滑动件25510从其未击发位置移动到其击发位置，以经由斜面25511部署存储在仓25501内的多个钉(未示出)。系统25500还包括电路25520，其被构造为向外科器械和/或系统25500的使用者指示安装在系统25500内的仓是否用完或部分用完，或安装在系统25500内的仓是否未用完并准备好击发。当滑动件25510处于其未击发位置时，滑动件25510接通电路25520，并且当滑动件25510处于其击发或部分击发位置时，滑动件25510不接通电路25520并且电路25520打开。Anothersurgical instrument system 25500 is shown in FIGS. 64 and 65 . Thesystem 25500 includes astaple cartridge 25501 that includes aslider 25510 that is movable between an unfired position and a fired position. The firingmember 25503 is configured to move theslider 25510 from its unfired position to its fired position to deploy a plurality of staples (not shown) stored within thecartridge 25501 via theramp 25511 .System 25500 also includescircuitry 25520 configured to indicate to a user of the surgical instrument and/orsystem 25500 whether a cartridge installed insystem 25500 is depleted or partially depleted, or if a cartridge installed insystem 25500 is not depleted and ready to fire. When theslider 25510 is in its unfired position, theslider 25510 closes thecircuit 25520, and when theslider 25510 is in its fired or partially fired position, theslider 25510 does not close thecircuit 25520 and thecircuit 25520 is open.

闭锁电路25520包括例如与外科器械柄部电通信的一对导体25521，以及定位在被构造成支撑钉仓25501的外科器械系统25500的夹具部分内的一对电接触件25522。电接触件25522定位成使得当钉仓25501完全坐置在系统25500中并且滑动件25510处于其未击发位置时(图65)，设置在滑动件25510的近侧面25512上的对应的垫或接触件25523接触电接触件25522。栓系部分或导体25524连接或电联接接触件25523并且附接到滑动件25510的近侧中间面25513。除了近侧面25512之外，接触件25522延伸到滑动件的底部面。当滑动件25510处于其未击发位置时，接触件25523与闭锁电路25520接合，并且接通闭锁电路25520指示未击发的，准备好击发的钉仓。当闭锁电路25520未接通时，可以使用软件和/或诸如本文所公开的那些的机械特征来闭锁外科器械。在至少一种情况下，闭锁电路25520与外科器械系统255500的控制器进行信号通信，该控制器在闭锁电路25520处于闭合状态时向击发驱动器的电动马达供应电力，并且防止当闭锁电路25520打开时向电动马达供应电力。Thelatch circuit 25520 includes, for example, a pair ofconductors 25521 in electrical communication with the handle of the surgical instrument, and a pair ofelectrical contacts 25522 positioned within a clamp portion of thesurgical instrument system 25500 configured to support thestaple cartridge 25501. Theelectrical contacts 25522 are positioned such that when thecartridge 25501 is fully seated in thesystem 25500 and theslider 25510 is in its unfired position (FIG. 65), corresponding pads or contacts provided on theproximal side 25512 of theslider 25510 25523 contactselectrical contact 25522. A tethered portion orconductor 25524 connects or electrically couples thecontact 25523 and is attached to theproximal mid-surface 25513 of theslider 25510. In addition to theproximal side 25512, thecontacts 25522 extend to the bottom side of the slider. When theslider 25510 is in its unfired position, thecontacts 25523 engage thelatch circuit 25520, and closing thelatch circuit 25520 indicates an unfired, ready-to-fire staple cartridge. When thelatch circuit 25520 is not closed, software and/or mechanical features such as those disclosed herein may be used to latch the surgical instrument. In at least one instance, thelockout circuit 25520 is in signal communication with a controller of the surgical instrument system 255500 that supplies power to the electric motor of the firing driver when thelockout circuit 25520 is in a closed state, and prevents when thelockout circuit 25520 is open Power is supplied to the electric motor.

在图66至图70中示出了系统25600的击发构件闭锁布置。系统25600包括击发构件25610、闭锁件25620和轴脊柱25601。轴脊柱25601容纳闭锁件25620和击发构件25610。击发构件25610包括远侧呈现的切割边缘25611，其被构造成在击发构件25610的钉击发冲程期间切断组织。当闭锁件25620被激活时，闭锁件25620被构造成卡扣击发构件25610并且从而准许击发构件25610穿过。除上述之外，当未用完的钉仓未定位在系统25600中时，闭锁件25620可以由系统25600的控制器激活。The firing member latching arrangement of thesystem 25600 is shown in FIGS. 66-70 .System 25600 includes firingmember 25610,latch 25620, andshaft spine 25601.Axle spine 25601 houses latch 25620 and firingmember 25610. The firingmember 25610 includes a distally presentedcutting edge 25611 configured to sever tissue during the staple firing stroke of the firingmember 25610. When thelatch 25620 is activated, thelatch 25620 is configured to snap the firingmember 25610 and thereby permit the firingmember 25610 to pass therethrough. In addition to the above, thelatch 25620 may be activated by the controller of thesystem 25600 when an unused staple cartridge is not positioned in thesystem 25600.

闭锁件25620包括螺线管25621和包括第一连杆25623和第二连杆25624的机械联接装置。连杆25623、25624附接在枢轴25622处。螺线管25621位于在脊柱25601内，使得螺线管25621可以向枢轴25622附近的联接装置施加力。闭锁件25620在图66和图67中示出处于其偏压的锁定位置。闭锁件25620还包括锁定主体或凸轮板25625，其可枢转地与第二连杆25624的端部联接。当螺线管25621处于其未致动的构造时，如图66和图67所示，凸轮板25625被偏压到刀带窗口25612中以卡扣击发构件25610。Thelatch 25620 includes asolenoid 25621 and a mechanical linkage including afirst link 25623 and asecond link 25624.Links 25623, 25624 are attached atpivot 25622. Thesolenoid 25621 is located within thespine 25601 so that thesolenoid 25621 can apply a force to the coupling near thepivot 25622. Thelatch 25620 is shown in its biased locked position in FIGS. 66 and 67 . Thelatch 25620 also includes a locking body orcam plate 25625 that is pivotally coupled to the end of thesecond link 25624. When thesolenoid 25621 is in its unactuated configuration, as shown in FIGS. 66 and 67 , thecam plate 25625 is biased into theknife belt window 25612 to snap the firingmember 25610.

在各种情况下，在击发构件25610中提供多个窗口。另一个窗口，诸如窗口25614，可包括另一个近侧表面。窗口25614可用作中间闭锁件以在操作的中间锁定击发构件25610。在诸如刀结合的情况下，可触发螺线管25621以将闭锁件25620释放到其锁定位置，以防止击发构件25610的进一步致动。在各种情况下，击发构件25610中的窗口的远侧表面可被构造成使得当击发构件25610向近侧缩回时，凸轮板25625可在远侧表面上滑动以防止在击发构件25610向近侧移动时锁定击发构件25610。在其它情况下，可期望在击发构件25610向近侧移动时锁定击发构件25610。In various cases, multiple windows are provided in the firingmember 25610. Another window, such aswindow 25614, can include another proximal surface. Thewindow 25614 can be used as an intermediate latch to lock the firingmember 25610 in the middle of operation. In situations such as knife engagement, thesolenoid 25621 can be triggered to release thelatch 25620 to its locked position to prevent further actuation of the firingmember 25610. In various cases, the distal surface of the window in the firingmember 25610 can be configured such that when the firingmember 25610 is retracted proximally, thecam plate 25625 can slide on the distal surface to prevent the firingmember 25610 from being proximally retracted.Locks firing member 25610 when moved sideways. In other cases, it may be desirable to lock the firingmember 25610 as the firingmember 25610 moves proximally.

在一些情况下，闭锁件可以构造成准许在一个方向上移动但是防止在另一个方向上移动。例如，当击发构件25610的远侧移动已被闭锁时，击发构件25610的轻微缩回可能是期望的。当在此类情况下向近侧缩回时，促使击发构件25610结合的区域中的组织可自然地解压缩，并且在等待组织解压缩的限定时间段之后，可激活螺线管25621以将闭锁件25620移动到其解锁位置(图68和图69)，因此准许击发构件25610再次向远侧推进。In some cases, the latch may be configured to permit movement in one direction but prevent movement in the other direction. For example, when distal movement of the firingmember 25610 has been blocked, slight retraction of the firingmember 25610 may be desirable. When retracted proximally under such conditions, tissue in the area where the firingmember 25610 is urged to engage can naturally decompress, and after waiting for a defined period of tissue decompression, thesolenoid 25621 can be activated to lock out Themember 25620 is moved to its unlocked position (FIGS. 68 and 69), thus permitting the firingmember 25610 to be advanced distally again.

图68至图70示出了闭锁件25620处于其解锁位置。在比较图66和图67与图68至图70时，可以看出，当致动时，螺线管25621将机械联接装置移动到共线构造，以将凸轮板25625滑出或迫使离开窗口25612以解锁击发构件25610。当螺线管25621移动机械联接装置时，滑块支撑件25603设置在脊柱25601内以引导凸轮板25625。例如，滑块支撑件25603在至少一种情况下控制凸轮板25625移动到线性路径。Figures 68-70 show thelatch 25620 in its unlocked position. When comparing Figures 66 and 67 with Figures 68-70, it can be seen that, when actuated, thesolenoid 25621 moves the mechanical linkage to a collinear configuration to slide or force thecam plate 25625 out of thewindow 25612 to unlock the firingmember 25610. Slider supports 25603 are positioned withinspine 25601 to guidecam plate 25625 assolenoid 25621 moves the mechanical linkage. For example,slider support 25603 controls movement ofcam plate 25625 to a linear path in at least one instance.

本文公开了各种实施方案，其包括闭锁件，该闭锁件被构造成在某些情况下防止击发构件向远侧推进。在许多情况下，闭锁件足以阻挡击发构件的远侧推进。在一些情况下，可期望具有多于一个的被构造成阻挡击发构件的远侧推进的闭锁件。在此类情况下，主要闭锁件和次级闭锁件可以阻挡击发构件的远侧推进。如下面更详细描述的，由于主要闭锁件被致动，可以致动次级闭锁件。例如，主要闭锁件可以防止击发构件的远侧推进，因为装载单元缺失钉仓夹具，钉仓夹具不正确地附接到装载单元，和/或钉仓夹具先前已经至少部分地击发，并且当击发构件的远侧位移受到主要闭锁件的阻挡时，可以致动次级闭锁件以辅助主要闭锁件阻挡击发构件的远侧推进。Various embodiments are disclosed herein that include a lockout configured to prevent distal advancement of the firing member under certain circumstances. In many cases, the lockout is sufficient to block distal advancement of the firing member. In some cases, it may be desirable to have more than one latch configured to block distal advancement of the firing member. In such cases, the primary and secondary lockouts may block distal advancement of the firing member. As described in more detail below, as the primary latch is actuated, the secondary latch may be actuated. For example, the primary lockout may prevent distal advancement of the firing member because the loading unit is missing a cartridge clip, the cartridge clip is improperly attached to the loading unit, and/or the cartridge clip has previously been at least partially fired, and when fired When distal displacement of the member is blocked by the primary latch, the secondary latch may be actuated to assist the primary latch in blocking distal advancement of the firing member.

现在转到图82和图83，装载单元包括轴21730和延伸通过轴21730的击发构件系统。击发构件系统包括第一或近侧击发构件21760和第二或远侧击发构件21762。在击发构件系统的钉击发冲程期间，近侧击发构件21760例如通过电动马达和/或手动曲柄向远侧推动。同样地，远侧击发构件21762被近侧击发构件21760向远侧推动。击发构件系统还包括闭锁件21780，闭锁件21780定位在近侧击发构件21760和远侧击发构件21762中间。闭锁件21780被构造成在钉击发冲程期间将击发力从近侧击发构件21760传递到远侧击发构件21762。在通过闭锁件21780传递的力超过在钉击发冲程期间预期的击发力和/或超过预先确定的阈值力的情况下，闭锁件21780移动到锁定构造，如图83所示并且如下文进一步更详细地描述的。Turning now to FIGS. 82 and 83 , the loading unit includes ashaft 21730 and a firing member system extending through theshaft 21730 . The firing member system includes a first orproximal firing member 21760 and a second ordistal firing member 21762. During the staple firing stroke of the firing member system, theproximal firing member 21760 is pushed distally, eg, by an electric motor and/or a hand crank. Likewise, thedistal firing member 21762 is urged distally by theproximal firing member 21760. The firing member system also includes alatch 21780 positioned intermediate theproximal firing member 21760 and thedistal firing member 21762. Thelatch 21780 is configured to transfer firing force from theproximal firing member 21760 to thedistal firing member 21762 during the staple firing stroke. In the event that the force transmitted through thelatch 21780 exceeds the expected firing force during the staple firing stroke and/or exceeds a predetermined threshold force, thelatch 21780 moves to the locked configuration, as shown in FIG. 83 and as further described below described in detail.

闭锁件21780包括锁定臂21782，该锁定臂21782在枢轴21784处可枢转地安装到近侧击发构件21760。锁定臂21782被构造成邻接限定在击发构件21762的近侧端部上的驱动表面21768并向远侧推动击发构件21762。在至少一种情况下，驱动表面21768形成例如锥形表面。闭锁件21780还包括偏压构件或弹簧21785，该偏压构件或弹簧21785被构造成将锁定臂21782抵靠驱动表面21768向内朝向解锁构造偏压，如图82所示。每个锁定臂21782包括从其延伸的销21783，该销21783被构造成将弹簧21785的端部安装到锁定臂21782。当闭锁件21780移动到锁定构造时，除上述之外，锁定臂21782相对于驱动表面21768滑动并向外张开或旋转成与轴21730接合。轴21730包括限定在轴中的齿21781的一个或多个齿条，该齿条21781由锁定臂21782接合并防止近侧击发构件21760向远侧推进。Thelatch 21780 includes alocking arm 21782 pivotally mounted to theproximal firing member 21760 at apivot 21784. The lockingarm 21782 is configured to abut thedrive surface 21768 defined on the proximal end of the firingmember 21762 and urge the firingmember 21762 distally. In at least one instance, thedrive surface 21768 forms, for example, a tapered surface. Thelatch 21780 also includes a biasing member orspring 21785 configured to bias thelocking arm 21782 inwardly toward the unlocked configuration against thedrive surface 21768, as shown in FIG. 82 . Each lockingarm 21782 includes apin 21783 extending therefrom that is configured to mount the end of aspring 21785 to thelocking arm 21782. When thelatch 21780 is moved to the locked configuration, in addition to the above, the lockingarm 21782 slides relative to thedrive surface 21768 and flares or rotates into engagement with theshaft 21730.Shaft 21730 includes one or more racks ofteeth 21781 defined in the shaft that are engaged by lockingarms 21782 and preventproximal firing member 21760 from being advanced distally.

除上述之外，当锁定臂21782向外位移时，弹簧21785弹性地拉伸。选择弹簧21785的刚度，使得当从近侧击发构件21760传递到远侧击发构件21762的力低于阈值力时，弹簧21785可将锁定臂21782抵靠驱动表面21768保持在它们的解锁构造中，但当从近侧击发构件21760传递到远侧击发构件21762的力超过阈值力时，准许锁定臂21782向外位移。在近侧击发构件21760和远侧击发构件21762之间传递的力在击发系统从钉仓击发钉时低于阈值力，并且在远侧击发构件21760被缺失的仓和/或用完的仓闭锁件阻挡时高于阈值力。在此类情况下，闭锁件21780响应于另一闭锁件阻挡钉击发系统的推进而部署。换句话说，闭锁件21780可以包括次级闭锁件，其与主要闭锁件配合以阻挡钉击发系统的推进。In addition to the above, when thelocking arm 21782 is displaced outward, thespring 21785 is elastically stretched. The stiffness of thespring 21785 is selected such that when the force transmitted from theproximal firing member 21760 to thedistal firing member 21762 is below a threshold force, thespring 21785 can hold the lockingarms 21782 in their unlocked configuration against thedrive surface 21768, but When the force transferred from theproximal firing member 21760 to thedistal firing member 21762 exceeds a threshold force, the lockingarms 21782 are permitted to displace outward. The force transferred between theproximal firing member 21760 and thedistal firing member 21762 is below a threshold force when the firing system fires staples from the staple cartridge, and thedistal firing member 21760 is locked by a missing and/or spent cartridge above the threshold force when the piece blocks. In such cases, thelatch 21780 deploys in response to another latch blocking advancement of the staple firing system. In other words, thelatch 21780 can include a secondary latch that cooperates with the primary latch to block advancement of the staple firing system.

在各种情况下，除上述之外，闭锁件21780可以为钉击发系统提供过载保护。比如，钉击发系统可以在击发冲程期间被卡住，并且闭锁件21780可以部署以停止钉击发冲程。在此类情况下，闭锁件21780可以将击发力或击发力的至少一部分传递到轴21730而不是钉仓。因此，闭锁件21780可以防止击发系统和/或钉仓被损坏，或至少进一步被损坏。在此类情况下，闭锁件21780响应于除了预先确定的闭锁件之外的缝合组件的状况而部署。再次参考图82和图83，齿齿条21781与钉击发系统的击发冲程的长度相同或更长，使得闭锁件21780可以在击发冲程期间的任何点处与齿架21781接合。In various circumstances, in addition to the above, thelatch 21780 may provide overload protection for the nail firing system. For example, the staple firing system can be stuck during the firing stroke, and thelatch 21780 can be deployed to stop the staple firing stroke. In such cases, thelatch 21780 may transmit the firing force or at least a portion of the firing force to theshaft 21730 instead of the staple cartridge. Accordingly, thelatch 21780 can prevent damage, or at least further damage, to the firing system and/or the staple cartridge. In such cases, thelatch 21780 deploys in response to conditions of the suture assembly other than the predetermined latch. Referring again to Figures 82 and 83, therack 21781 is the same length or longer than the firing stroke of the staple firing system, so that thelatch 21780 can engage therack 21781 at any point during the firing stroke.

当从近侧击发构件21760传递到远侧击发构件21762的力下降到力阈值以下时，弹簧21785可以弹性地将锁定臂21782返回到其解锁构造并且与远侧击发构件21762的驱动表面21768接合。此时，如果促使第二闭锁件21780致动的条件已经减弱，则可以完成击发冲程。否则，近侧击发构件21760可以缩回。When the force transmitted from theproximal firing member 21760 to thedistal firing member 21762 falls below the force threshold, thespring 21785 can resiliently return thelocking arm 21782 to its unlocked configuration and engage thedrive surface 21768 of thedistal firing member 21762. At this point, if the conditions prompting actuation of thesecond latch 21780 have subsided, the firing stroke may be completed. Otherwise, theproximal firing member 21760 can be retracted.

现在转向图92至图95，装载单元包括轴24530和延伸通过轴24530的钉击发系统。钉击发系统包括近侧击发构件24560和远侧击发构件24562。例如，在钉击发系统的钉击发冲程期间，近侧击发构件24560通过电动马达和/或手动曲柄向远侧推动。同样地，远侧击发构件24562被近侧击发构件24560向远侧推动。钉击发系统还包括闭锁件24580，该闭锁件24580定位在近侧击发构件24560和远侧击发构件24562中间。闭锁件24580被构造成在钉击发冲程期间将击发力从近侧击发构件24560传递到远侧击发构件24562。在通过闭锁件24580传递的力超过在钉击发冲程期间预期的击发力和/或超过预先确定的阈值力的情况下，闭锁件24580移动到锁定构造，如图94和图95所示。Turning now to FIGS. 92-95 , the loading unit includes ashaft 24530 and a staple firing system extending through theshaft 24530 . The staple firing system includes aproximal firing member 24560 and adistal firing member 24562. For example, during the staple firing stroke of the staple firing system, theproximal firing member 24560 is pushed distally by the electric motor and/or hand crank. Likewise, thedistal firing member 24562 is urged distally by theproximal firing member 24560. The staple firing system also includes alatch 24580 positioned intermediate theproximal firing member 24560 and thedistal firing member 24562. Thelatch 24580 is configured to transfer firing force from theproximal firing member 24560 to thedistal firing member 24562 during the staple firing stroke. In the event that the force transmitted through thelatch 24580 exceeds the expected firing force during the staple firing stroke and/or exceeds a predetermined threshold force, thelatch 24580 moves to the locked configuration, as shown in FIGS. 94 and 95 .

主要参考图93和图95，闭锁件24580包括例如基本上为C形的构造，其围绕远侧击发构件24562的一部分延伸。闭锁件24580包括锁定臂24584，当闭锁件24580处于其未致动或解锁构造时，锁定臂24584夹持远侧击发构件24562，如图92和图93所示。闭锁件24580还包括驱动突片24582，当近侧击发构件24560在钉击发系统的钉击发冲程期间向远侧驱动时，该驱动突片24582与近侧击发构件24560接触。当闭锁件24580被近侧击发构件24560向远侧推动时，闭锁件24580邻接限定在远侧击发构件24562上的驱动表面24564并向远侧推动远侧击发构件24562。因此，闭锁件24580将推力从近侧击发构件24560通过锁定臂24584传递到驱动表面24564中。Referring primarily to FIGS. 93 and 95 , thelatch 24580 includes, for example, a substantially C-shaped configuration that extends around a portion of thedistal firing member 24562. Thelatch 24580 includes alocking arm 24584 that grips thedistal firing member 24562 when thelatch 24580 is in its unactuated or unlocked configuration, as shown in FIGS. 92 and 93 . Thelatch 24580 also includes adrive tab 24582 that contacts theproximal firing member 24560 when theproximal firing member 24560 is driven distally during the staple firing stroke of the staple firing system. When thelatch 24580 is urged distally by theproximal firing member 24560, thelatch 24580 abuts thedrive surface 24564 defined on thedistal firing member 24562 and pushes thedistal firing member 24562 distally. Accordingly, thelatch 24580 transmits thrust from theproximal firing member 24560 through the lockingarm 24584 into thedrive surface 24564.

主要参考图92，驱动突片24582与锁定臂24584不共面；相反，驱动突片24582从由锁定臂24584限定的平面侧向延伸。更具体地，驱动突片24582包括至少在闭锁件24580处于其未致动构造时从锁定臂24584翻倒的升高部分。闭锁件24580被构造成只要被传递通过闭锁件24580的推力低于阈值力就保持在其未致动的构造中。完成击发冲程所需的推力低于该阈值力。当传递通过闭锁件24580的推力超过阈值力时，闭锁件24580塌缩成其致动构造，如图94和图95所示。例如，当远侧击发构件24562邻接钉仓中的缺失钉仓和/或用完的钉仓闭锁件时，推力可以超过阈值力。Referring primarily to FIG. 92 , thedrive tabs 24582 are not coplanar with the lockingarms 24584 ; instead, thedrive tabs 24582 extend laterally from the plane defined by the lockingarms 24584 . More specifically, thedrive tab 24582 includes a raised portion that tip over from the lockingarm 24584 at least when thelatch 24580 is in its unactuated configuration. Thelatch 24580 is configured to remain in its unactuated configuration as long as the thrust force transmitted through thelatch 24580 is below a threshold force. The thrust required to complete the firing stroke is below this threshold force. When the thrust force transmitted through thelatch 24580 exceeds a threshold force, thelatch 24580 collapses into its actuated configuration, as shown in FIGS. 94 and 95 . For example, the thrust force may exceed a threshold force when thedistal firing member 24562 abuts a missing staple cartridge and/or a spent staple cartridge latch in the staple cartridge.

再次参考图94和图95，当闭锁件24580移动到其致动构造时，锁定臂24584径向向外张开以接合轴24530。在至少一种情况下，轴24530可以包括限定在轴中的凹陷部24534，该凹陷部24534被构造成接收锁定臂24584。凹陷部24534限定在轴24530中，使得当击发系统的远侧推进被缺失的仓和/或用完的仓闭锁件阻挡时，锁定臂24584与凹陷部24534对准。一旦锁定臂24584位于凹陷部24534中，闭锁件24580也可以阻挡击发系统的远侧推进。在各种情况下，凹陷部24534被定位和布置成在击发驱动器的切割构件切入组织之前停止击发构件24560。当近侧击发构件24560缩回并且施加到闭锁件24580的推动载荷下降到阈值力以下时，闭锁件24580可以弹性地返回到其未致动的构造。此时，可以将未用完的仓放置在装载单元中以使缺失的仓和/或用完的仓闭锁件失效，使得击发系统可以通过其钉击发冲程向远侧推进。然而，在任何时候，近侧击发构件24560均可以缩回以缩回远侧击发构件24562。Referring again to FIGS. 94 and 95 , when thelatch 24580 is moved to its actuated configuration, the lockingarms 24584 flare radially outward to engage theshaft 24530 . In at least one instance, theshaft 24530 can include arecess 24534 defined in the shaft, therecess 24534 being configured to receive thelocking arm 24584 . Arecess 24534 is defined in theshaft 24530 such that thelocking arm 24584 is aligned with therecess 24534 when distal advancement of the firing system is blocked by a missing cartridge and/or a spent cartridge latch. Thelatch 24580 may also block distal advancement of the firing system once the lockingarm 24584 is in therecess 24534. In each case, therecess 24534 is positioned and arranged to stop the firingmember 24560 prior to the cutting member of the firing driver cutting into the tissue. When theproximal firing member 24560 is retracted and the push load applied to thelatch 24580 falls below the threshold force, thelatch 24580 can elastically return to its unactuated configuration. At this point, an unused cartridge can be placed in the loading unit to deactivate the missing cartridge and/or the spent cartridge latch so that the firing system can be advanced distally through its staple firing stroke. However, at any time, theproximal firing member 24560 can be retracted to retract thedistal firing member 24562.

如果钉击发系统加速太快，则可以致动上述闭锁件的阈值力。换句话说，钉击发系统中的加速度峰值可以导致超过闭锁件的阈值力的力峰值，这导致闭锁件停止钉击发系统。例如，当机械地联接到钉击发系统的击发触发器被挤得太快并且或者电源突然施加到钉击发系统的电动马达时，可以出现此类情况。在至少一种情况下，例如，当施加到电动马达的电力被不正确地调制时和/或当马达控制器中已经发生软件故障时，可以发生加速度峰值。此种加速度峰值和力峰值通常是瞬态的，并且一旦通过钉击发系统传递的力下降回到阈值力以下，就可以完成击发冲程。If the nail firing system accelerates too quickly, the threshold force above which the latch can be actuated. In other words, acceleration peaks in the staple firing system can result in force peaks that exceed the latch's threshold force, which causes the latch to stop the staple firing system. Such a situation can arise, for example, when a firing trigger mechanically coupled to the staple firing system is squeezed too quickly and power is suddenly applied to the electric motor of the staple firing system. Acceleration spikes can occur in at least one situation, for example, when power applied to the electric motor is improperly modulated and/or when a software fault has occurred in the motor controller. Such acceleration peaks and force peaks are generally transient and the firing stroke can be completed once the force delivered by the nail firing system falls back below the threshold force.

现在转到图84，缝合组件包括轴21830和延伸穿过其中的击发构件21860。缝合组件还包括闭锁系统21880。闭锁系统21880包括锁定臂21882，该锁定臂21882围绕枢轴21884可旋转地安装到钉击发构件21860。每个锁定臂21882可在未致动位置和致动位置之间旋转，该未致动位置在图84中以实线示出，致动位置在图84中以虚线示出。闭锁系统21880还包括悬臂弹簧21885，该悬臂弹簧21885安装到钉击发构件21860，该钉击发构件21860被构造成将锁定臂21882偏压到它们的未致动位置。缝合组件还包括安装到击发构件21860的致动器21862，当击发构件21860向远侧移动时，致动器被构造成抵靠轴21830的壳体滑动或拖动。当击发构件21860加速太快或高于阈值水平时，致动器21862和轴21830之间的阻力将减慢或夹持致动器21862并允许击发构件21860相对于致动器21862滑动。在此类情况下，致动器21862和击发构件21860之间的相对运动将锁定臂21882向外驱动成与轴21830中限定的齿21881的齿条接合，以停止、妨碍或减缓钉击发系统的远侧前进。Turning now to Figure 84, the suturing assembly includes ashaft 21830 and a firingmember 21860 extending therethrough. The suture assembly also includes alatching system 21880. Thelatching system 21880 includes alocking arm 21882 rotatably mounted to thestaple firing member 21860 about apivot 21884. Each lockingarm 21882 is rotatable between an unactuated position shown in solid lines in FIG. 84 and an actuated position shown in phantom in FIG. 84 . Thelatching system 21880 also includes acantilever spring 21885 mounted to thestaple firing member 21860 configured to bias the lockingarms 21882 to their unactuated positions. The suturing assembly also includes anactuator 21862 mounted to the firingmember 21860 that is configured to slide or drag against the housing of theshaft 21830 when the firingmember 21860 is moved distally. When the firingmember 21860 is accelerated too quickly or above a threshold level, resistance between theactuator 21862 and theshaft 21830 will slow or clamp theactuator 21862 and allow the firingmember 21860 to slide relative to theactuator 21862. In such cases, relative movement between theactuator 21862 and the firingmember 21860 drives the lockingarms 21882 outwardly into engagement with the rack ofteeth 21881 defined in theshaft 21830 to stop, hinder or slow down the nail firing system. Advance far side.

现在转到图85，缝合组件包括轴21930和击发构件21960，该击发构件21960被构造成在轴21930内平移。缝合组件还包括闭锁系统21980，该闭锁系统21980包括锁定臂21982，该锁定臂21982围绕枢轴21984可旋转地安装到钉击发构件21960。锁定臂21982可在未致动位置和致动位置之间旋转，该未致动位置在图85中以实线示出，致动位置在图85中以虚线示出。闭锁系统21980还包括安装到钉击发构件21960和锁定臂21982的螺旋弹簧21985，该螺旋弹簧21985被构造成将锁定臂21982偏压到其未致动位置。闭锁系统21980还包括安装到锁定臂21982的致动器或重物21989，当击发构件21960向远侧加速时，致动器被或重物构造成惯性地旋转锁定臂21982。当击发构件21960加速太快或高于阈值水平时，由重物21989产生的惯性力足以克服弹簧21985的偏压力并使锁定臂21982旋转成与限定在轴21930中的齿21981的齿条接合。在此类情况下，闭锁系统21890将停止、妨碍或减慢钉击发系统的远侧行进，直到击发构件21960的加速度下降到阈值以下并且弹簧21985可以将锁定臂21982拉出与齿21981的齿条的接合。Turning now to FIG. 85, the suturing assembly includes ashaft 21930 and a firingmember 21960 configured to translate within theshaft 21930. The stapling assembly also includes alatching system 21980 that includes alocking arm 21982 rotatably mounted to thestaple firing member 21960 about a pivot 21984. The lockingarm 21982 is rotatable between an unactuated position shown in solid lines in FIG. 85 and an actuated position shown in dashed lines in FIG. 85 . Thelatching system 21980 also includes acoil spring 21985 mounted to thestaple firing member 21960 and thelocking arm 21982, thecoil spring 21985 being configured to bias thelocking arm 21982 to its unactuated position. Thelatching system 21980 also includes an actuator orweight 21989 mounted to thelocking arm 21982 that is configured to inertially rotate thelocking arm 21982 when the firingmember 21960 is accelerated distally. When the firingmember 21960 accelerates too quickly or above a threshold level, the inertial force created by theweight 21989 is sufficient to overcome the biasing force of thespring 21985 and rotate thelocking arm 21982 into engagement with the rack ofteeth 21981 defined in theshaft 21930. In such a case, the latching system 21890 will stop, hinder or slow the distal travel of the staple firing system until the acceleration of the firingmember 21960 falls below the threshold and thespring 21985 can pull thelocking arm 21982 out of the rack with teeth 21981 's engagement.

除了上述之外或代替上述内容，缝合组件可以包括用于调节钉击发系统的速度的装置，其在各种情况下可以减少或平滑钉击发系统内产生的加速度峰值。现在转向图86，缝合组件可以包括轴22030和钉击发构件22060，该钉击发构件22060被构造成在轴22030内平移。缝合组件还包括阻尼系统22080，该阻尼系统22080包括阻尼构件或缓冲器22081，阻尼构件或缓冲器被构造成减慢钉击发构件22060的远侧平移和/或近侧平移。例如，阻尼构件22081由顺应性和/或弹性材料构成，诸如橡胶，当击发构件22060接触阻尼构件时，顺应性和/或弹性材料被构造成产生与施加到击发构件22060的推力相反的阻尼力。击发构件22060延伸通过限定在阻尼构件22081中的孔隙，并且包括被构造成接合阻尼构件22081的环形脊22082。例如，尽管在图86中仅示出了一个阻尼构件22081和轴脊22082，但是缝合组件可以包括任何合适数量的阻尼构件22081和/或轴脊22082。In addition to or in lieu of the foregoing, the stapling assembly may include means for adjusting the speed of the staple firing system, which in various circumstances may reduce or smoothen acceleration peaks generated within the staple firing system. Turning now to FIG. 86, the stapling assembly can include ashaft 22030 and astaple firing member 22060 configured to translate within theshaft 22030. The stapling assembly also includes a dampingsystem 22080 that includes a damping member orbumper 22081 configured to slow distal and/or proximal translation of thestaple firing member 22060. For example, the dampingmember 22081 is constructed of a compliant and/or resilient material, such as rubber, that is configured to generate a damping force that opposes the thrust force applied to the firingmember 22060 when the firingmember 22060 contacts the damping member . The firingmember 22060 extends through an aperture defined in the dampingmember 22081 and includes anannular ridge 22082 configured to engage the dampingmember 22081 . For example, although only one dampingmember 22081 andshaft ridge 22082 are shown in Figure 86, the suture assembly may include any suitable number of dampingmembers 22081 and/orshaft ridges 22082.

除上述之外，缓冲器22081定位在轴22030内，使得脊22082恰好在击发构件22060到达缺失的仓和/或用完的仓闭锁件之前接触缓冲器22081。在此类情况下，阻尼系统22080可以在击发构件22060到达闭锁件之前降低击发构件22060的速度，并且因此减小击发构件22060撞击通过或无意地使闭锁件失效的可能性。In addition to the above, thebumper 22081 is positioned within theshaft 22030 such that theridge 22082 contacts thebumper 22081 just before the firingmember 22060 reaches the missing cartridge and/or the spent cartridge latch. In such cases, the dampingsystem 22080 may reduce the velocity of the firingmember 22060 before the firingmember 22060 reaches the latch, and thus reduce the likelihood that the firingmember 22060 will strike through or inadvertently fail the latch.

现在转到图87，缝合组件可以包括轴22130和钉击发构件22160，该钉击发构件22160被构造成在轴22130内平移。缝合组件还包括液压阻尼系统22180，该液压阻尼系统22180包括汽缸组件，该汽缸组件被构造成在其钉击发冲程期间使击发构件22160减慢。汽缸组件包括可滑动地定位在腔室22183中的输入活塞22181，该活塞22181与腔室22183的侧壁密封地接合。汽缸组件还包括可滑动地定位在腔室22185中的输出活塞22184，该输出活塞22184与腔室22185的侧壁密封地接合。如图87所示，腔室22183的一部分经由限制孔口22189与腔室22185的一部分流体连通。不可压缩或基本上不可压缩的流体22182容纳在输入活塞22181和输出活塞22184之间的腔室22183和22185中。在至少一种情况下，流体22182包括例如液压流体。在某些情况下，流体22182包括例如盐水。当击发构件22160向远侧推进时，击发构件22160或限定在击发构件22160上的肩部接触限定在输入活塞22181上的凸轮或成角度的表面，并将输入活塞向下驱动到腔室22183中。在此类情况下，输入活塞22181将流体22182位移到腔室22185中，腔室22185继而又使输出活塞22184在腔室22185内位移。输出活塞22184、流体22182和输入活塞22181的运动由位于腔室22185中的弹簧22186抵抗。因此，阻尼系统22180将曳力施加到击发构件22160，该曳力随着击发构件22160的速度的增加而成比例地增加，并且可以限制击发构件22160的最大速度。类似于上文，阻尼系统22180可以定位在轴22130中，使得击发构件22160恰好在击发构件22160到达闭锁件之前或至少在击发构件22160到达闭锁件之前接触阻尼系统22180。Turning now to FIG. 87 , the stapling assembly can include ashaft 22130 and astaple firing member 22160 configured to translate within theshaft 22130. The suture assembly also includes a hydraulic dampingsystem 22180 that includes a cylinder assembly configured to slow the firingmember 22160 during its staple firing stroke. The cylinder assembly includes aninput piston 22181 slidably positioned in achamber 22183 that sealingly engages a sidewall of thechamber 22183 . The cylinder assembly also includes anoutput piston 22184 slidably positioned in thechamber 22185 that sealingly engages a sidewall of thechamber 22185 . As shown in FIG. 87, a portion of thechamber 22183 is in fluid communication with a portion of thechamber 22185 via arestrictive orifice 22189. Incompressible or substantiallyincompressible fluid 22182 is contained inchambers 22183 and 22185 betweeninput piston 22181 andoutput piston 22184. In at least one instance, thefluid 22182 includes, for example, hydraulic fluid. In some cases, thefluid 22182 includes, for example, saline. As the firingmember 22160 is advanced distally, the firingmember 22160 or a shoulder defined on the firingmember 22160 contacts a cam or angled surface defined on theinput piston 22181 and drives the input piston down into thechamber 22183 . In such cases,input piston 22181 displacesfluid 22182 intochamber 22185, which in turn displacesoutput piston 22184 withinchamber 22185. Movement ofoutput piston 22184 ,fluid 22182 andinput piston 22181 is resisted byspring 22186 located inchamber 22185 . Accordingly, the dampingsystem 22180 applies a drag force to the firingmember 22160 that increases proportionally with the speed of the firingmember 22160 and can limit the maximum speed of the firingmember 22160. Similar to the above, the dampingsystem 22180 can be positioned in theshaft 22130 such that the firingmember 22160 contacts the dampingsystem 22180 just before the firingmember 22160 reaches the latch, or at least before the firingmember 22160 reaches the latch.

现在转到图89，缝合组件可以包括轴22330和可在轴22330内滑动的击发构件22360。缝合组件还包括气动活塞布置22380，该气动活塞布置22380被构造成将曳力施加到击发构件22360。击发构件22360包括延伸通过限定在轴22330中的支撑件的圆柱形或至少基本上圆柱形的杆，以及可滑动地定位在限定在轴22330中的汽缸22383中的整体形成的活塞22362。活塞布置22380包括一个或多个活塞密封件22382，该活塞密封件22382坐置在围绕活塞22362延伸的密封凹槽内。活塞密封件22382与活塞22362和汽缸22383的汽缸壁22381密封地接合。活塞布置22380还包括一个或多个密封件22361，其坐置在限定在轴支撑件中的密封凹槽中，该密封凹槽与轴22330和击发构件22360密封地接合。在各种情况下，密封件22361和22383包括例如顺应性O形环。在任何情况下，击发构件22360的远侧位移压缩汽缸22383中的空气并强迫压缩空气通过限定在轴22330中的排气口22363。该布置将曳力施加到击发构件22360，该曳力与击发构件22360的速度成比例地增加。Turning now to FIG. 89 , the suturing assembly can include ashaft 22330 and a firingmember 22360 slidable within theshaft 22330. The suture assembly also includes apneumatic piston arrangement 22380 configured to apply a drag force to the firingmember 22360. The firingmember 22360 includes a cylindrical or at least substantially cylindrical rod extending through a support defined in theshaft 22330, and an integrally formedpiston 22362 slidably positioned in acylinder 22383 defined in theshaft 22330.Piston arrangement 22380 includes one or more piston seals 22382 seated within sealing grooves extending aroundpiston 22362.Piston seal 22382 sealingly engagespiston 22362 andcylinder wall 22381 ofcylinder 22383. Thepiston arrangement 22380 also includes one ormore seals 22361 seated in seal grooves defined in the shaft support that sealingly engage theshaft 22330 and the firingmember 22360. In each case, seals 22361 and 22383 include, for example, compliant O-rings. In any event, distal displacement of firingmember 22360 compresses air incylinder 22383 and forces the compressed air through exhaust port 22363 defined inshaft 22330. This arrangement applies a drag force to the firingmember 22360 that increases proportionally to the velocity of the firingmember 22360.

除上述之外，可选择排气口22363的直径和/或长度以便以期望的方式限制击发构件22360的速度。此外，当击发构件22360向远侧推进并向近侧缩回时，密封件22382与轴22330密封地接合，因此，当击发构件22360向远侧推进并向近侧缩回时，活塞布置22380将曳力施加到击发构件22360。在至少一个实施方案中，阀，诸如单向阀，例如可以相对于排气口22363定位和布置。当击发构件22360向远侧推进时，该阀可以提供具有较小直径的孔，并且当击发构件22360向近侧缩回时，该孔可以提供具有较大直径的孔。在此类情况下，与当击发构件22360向近侧缩回给定速度时相比，当击发构件22360向远侧推进时，排气口可以将更大的曳力施加到击发构件22360。因此，阀可以提供不同的方向速度限制。In addition to the above, the diameter and/or length of the vent 22363 may be selected to limit the velocity of the firingmember 22360 in a desired manner. Additionally, as the firingmember 22360 is advanced distally and retracted proximally, theseal 22382 sealingly engages theshaft 22330, so that when the firingmember 22360 is advanced distally and retracted proximally, thepiston arrangement 22380 will A drag force is applied to the firingmember 22360. In at least one embodiment, a valve, such as a one-way valve, may be positioned and arranged relative to the exhaust port 22363, for example. The valve may provide a hole with a smaller diameter when the firingmember 22360 is advanced distally, and a hole with a larger diameter when the firingmember 22360 is retracted proximally. In such a case, the vent may apply a greater drag force to the firingmember 22360 when the firingmember 22360 is advanced distally than when the firingmember 22360 is retracted proximally for a given speed. Therefore, the valve can provide different directional speed limits.

现在转向图88，缝合组件可以包括钉击发轴22060，其向远侧位移以从钉仓射出钉。缝合组件还包括用于将电磁曳力和/或磁性曳力施加到钉击发轴22260的装置。在至少一种情况下，缝合组件包括卷绕的导体线圈22280，其例如由电源诸如电池供电，使得电流流过线圈22280。卷绕的导体线圈22280一旦被供电就产生磁场，该磁场与限定在轴22260中和/或附接到轴22260的磁性元件22282相互作用。在至少一种情况下，磁性元件22282包括例如永磁体。电源的极性被施加到线圈22280，使得线圈22280产生磁场，当击发构件22260接近线圈22280时，该磁场将排斥力施加到铁磁元件22282，并且因此在钉击发冲程期间将曳力施加到击发构件22360。由线圈22280产生的磁场的强度(intensity)或强度(strength)在线圈22280附近更强，并且因此，施加到击发构件22360的曳力将在线圈22280附近更大。Turning now to Figure 88, the stapling assembly can include astaple firing shaft 22060 that is distally displaced to eject staples from the staple cartridge. The suture assembly also includes means for applying electromagnetic and/or magnetic drag to thestaple firing shaft 22260. In at least one instance, the suture assembly includes awound conductor coil 22280, which is powered, for example, by a power source such as a battery, such that electrical current flows through thecoil 22280. Thewound conductor coil 22280, once powered, generates a magnetic field that interacts with themagnetic element 22282 defined in and/or attached to theshaft 22260. In at least one instance, themagnetic element 22282 includes, for example, a permanent magnet. The polarity of the power source is applied to thecoil 22280, causing thecoil 22280 to generate a magnetic field that applies a repulsive force to theferromagnetic element 22282 as the firingmember 22260 approaches thecoil 22280, and thus applies a drag force to the firing during the nail firingstroke Member 22360. The intensity or strength of the magnetic field generated by thecoil 22280 is stronger near thecoil 22280, and therefore, the drag force applied to the firingmember 22360 will be greater near thecoil 22280.

根据上述情况，线圈22280在被供电时可以用作制动器，并且在某些情况下，例如在钉击发冲程结束时停止或至少有助于停止击发构件22360的纵向移动。在某些情况下，施加到线圈22280的电压极性可以反转，以在击发构件22360的缩回冲程期间反转通过线圈22280的电流。在此类情况下，当击发构件22360远离线圈22280缩回时，线圈22280可以将制动力施加到击发构件22360。尽管在图88中仅示出了一个线圈22280，但是缝合组件可以包括任何合适数量的可通电线圈。除了上述之外或代替上述内容，缝合组件可以包括安装到缝合组件的轴的一个或多个永磁体，其可以将磁性制动力施加到钉击发构件。In light of the above, thecoil 22280 may act as a brake when energized, and under certain circumstances, such as at the end of the staple firing stroke, stop or at least help stop longitudinal movement of the firingmember 22360. In some cases, the polarity of the voltage applied to thecoil 22280 can be reversed to reverse the current flow through thecoil 22280 during the retraction stroke of the firingmember 22360. In such a case, thecoil 22280 may apply a braking force to the firingmember 22360 as the firingmember 22360 is retracted away from thecoil 22280. Although only onecoil 22280 is shown in Figure 88, the suture assembly may include any suitable number of energizable coils. In addition to or in lieu of the above, the stapling assembly can include one or more permanent magnets mounted to the shaft of the stapling assembly that can apply a magnetic braking force to the staple firing member.

在至少一个实施方案中，再次参考图88，电源未施加到线圈22280，并且线圈22280可以用作电/感应制动器。在此类实施方案中，磁性元件22282通过线圈22280的移动在线圈22280中产生电流，该电流继而产生与磁性元件22282的移动相反的磁场。当磁性元件22282相对于线圈22280缓慢移动时，相反的磁场在击发构件22260上运用可忽略的制动力。当磁性元件22282相对于线圈22280快速移动时，相反的磁场强得多并且将更强的制动力施加到击发构件22260。线圈22280和磁性元件22282可以定位和布置成使得制动力恰好在击发构件22260到达缺失的仓和/或用完的仓闭锁件之前或至少在此之前施加到击发构件22260。In at least one embodiment, referring again to FIG. 88, power is not applied tocoil 22280, andcoil 22280 may function as an electrical/inductive brake. In such embodiments, the movement of themagnetic element 22282 through thecoil 22280 generates a current in thecoil 22280, which in turn generates a magnetic field that opposes the movement of themagnetic element 22282. When themagnetic element 22282 is moved slowly relative to thecoil 22280, the opposing magnetic field exerts negligible braking force on the firingmember 22260. When themagnetic element 22282 is moved rapidly relative to thecoil 22280, the opposing magnetic field is much stronger and applies a stronger braking force to the firingmember 22260. Thecoil 22280 and themagnetic element 22282 can be positioned and arranged such that a braking force is applied to the firingmember 22260 just before or at least before the firingmember 22260 reaches the missing cartridge and/or the spent cartridge latch.

如上所述，钉击发系统的击发构件可以由电动马达驱动。可包括处理器并且可以实现为微控制器的马达控制器可以用于控制施加到电动马达的电压，并且因此控制钉击发构件的速度。在某些情况下，马达控制器可以利用脉冲宽度调制(PWM)和/或频率调制(FM)，例如，来控制电动马达的速度。在其它情况下，马达控制器可不调制供应到电动马达的电力。在任一种情况下，缝合组件可以包括与马达控制器通信的传感器系统，该传感器系统被构造成检测未用完的钉仓或未用完的钉仓夹具是否已附接到缝合组件。在传感器系统检测到未用完的钉仓附接到缝合组件的情况下，马达控制器可以识别来自传感器系统的信号(该信号指示未用完的钉仓的存在)，并且当缝合组件的使用者致动钉击发系统时操作钉击发系统的电动马达。在传感器系统没有检测到附接到缝合组件的未用完的钉仓的情况下，马达控制器接收来自传感器系统的信号(该信号指示未用完的仓未附接到缝合组件)，并且防止电动马达操作钉击发系统。此种布置可以包括电子或软件闭锁件。As mentioned above, the firing member of the staple firing system may be driven by an electric motor. A motor controller, which may include a processor and may be implemented as a microcontroller, may be used to control the voltage applied to the electric motor, and thus the speed of the staple firing member. In some cases, the motor controller may utilize pulse width modulation (PWM) and/or frequency modulation (FM), for example, to control the speed of the electric motor. In other cases, the motor controller may not modulate the power supplied to the electric motor. In either case, the stapling assembly can include a sensor system in communication with the motor controller, the sensor system being configured to detect whether an unspent staple cartridge or an unspent staple cartridge clip has been attached to the stapling assembly. In the event that the sensor system detects that an unused staple cartridge is attached to the stapling assembly, the motor controller can identify a signal from the sensor system indicating the presence of the unused staple cartridge, and when the stapling assembly is used An electric motor that operates the nail firing system when the user actuates the nail firing system. In the event that the sensor system does not detect an unused staple cartridge attached to the stapling assembly, the motor controller receives a signal from the sensor system indicating that the unused cartridge is not attached to the stapling assembly, and prevents The electric motor operates the nail firing system. Such arrangements may include electronic or software latches.

除了上述之外或代替上述内容，缝合系统可以包括传感器系统，该传感器系统被构造成跟踪钉击发构件的位移。参考图90，缝合组件22400的钉击发构件22460能够沿钉击发路径22463在近侧未击发位置和远侧击发位置之间移动。例如，可检测的磁性元件22461安装到钉击发构件22460，其沿钉击发路径22463移动或至少基本上沿钉击发路径22463移动。在至少一种情况下，磁性元件22461是永磁体，例如，其由铁、镍和/或任何其它合适的材料构成。传感器系统包括第一或近侧传感器22401’和第二或远侧传感器22401，该第一或近侧传感器22401’和第二或远侧传感器22401被构造成在磁性元件22461与可平移构件22460一起沿钉击发路径22463移动时检测磁性元件22461。第一传感器22401’和第二传感器22401各自包括霍尔效应传感器；然而，传感器22401’和22401可以包括任何合适的传感器。传感器22401’和22401输出根据它们与磁性元件22461的相应距离而变化的电压(当距离小时输出较高电压，当距离较大时输出较小电压)。In addition to or in lieu of the foregoing, the stapling system may include a sensor system configured to track displacement of the staple firing member. 90, thestaple firing member 22460 of the staplingassembly 22400 is movable along astaple firing path 22463 between a proximal unfired position and a distal fired position. For example, a detectablemagnetic element 22461 is mounted to thestaple firing member 22460 that moves along or at least substantially along thestaple firing path 22463. In at least one instance, themagnetic element 22461 is a permanent magnet, eg, composed of iron, nickel, and/or any other suitable material. The sensor system includes a first or proximal sensor 22401' and a second ordistal sensor 22401 configured to be in conjunction with atranslatable member 22460 at amagnetic element 22461Magnetic element 22461 is detected while moving alongstaple firing path 22463. The first sensor 22401' and thesecond sensor 22401 each comprise a Hall effect sensor; however, thesensors 22401' and 22401 may comprise any suitable sensor. Thesensors 22401' and 22401 output voltages that vary according to their respective distances from the magnetic element 22461 (higher voltages are output when the distances are small, and smaller voltages are outputted when the distances are large).

除上述之外，传感器系统包括传感器电路，该传感器电路尤其包括例如与传感器22401’和22401通信的电压源22403，该电压源22403向传感器22401’和22401供电。传感器电路还包括与第一传感器22401’通信的第一开关22405’和与第二传感器22401通信的第二开关22405。在至少一种情况下，例如，开关22401’和22401各自包括晶体管，诸如FET。传感器22401’、22401的输出分别连接到开关22405’、22405的中央(栅极)终端。在钉击发构件22460的击发冲程之前，来自传感器22401’、22401的输出电压高，使得第一开关22405’和第二开关22405处于闭合状态。In addition to the above, the sensor system includes a sensor circuit including, for example, avoltage source 22403 in communication with the sensors 22401' The sensor circuit also includes a first switch 22405' in communication with the first sensor 22401' and asecond switch 22405 in communication with thesecond sensor 22401. In at least one instance, switches 22401' and 22401 each comprise a transistor, such as a FET, for example. The outputs ofsensors 22401', 22401 are connected to the center (gate) terminals ofswitches 22405', 22405, respectively. Before the firing stroke of thestaple firing member 22460, the output voltage from the sensors 22401', 22401 is high, causing the first switch 22405' and thesecond switch 22405 to be in a closed state.

当磁性元件22461经过第一传感器22401’时，第一传感器22401’的电压输出足以在闭合状态和打开状态之间改变第一开关。类似地，当磁性元件22461经过第二传感器22401时，第二传感器22401的电压输出足以在闭合状态和打开状态之间改变第二开关22405。当开关22405’和22405都处于打开状态时，接地电位被施加到运算放大器电路22406。运算放大器电路22406与马达控制器的微控制器22490的输入通道进行信号通信，并且当接地电位施加到运算放大器电路22406时，微控制器22490从电路22406接收接地信号。When themagnetic element 22461 passes the first sensor 22401', the voltage output of the first sensor 22401' is sufficient to change the first switch between a closed state and an open state. Similarly, when themagnetic element 22461 passes thesecond sensor 22401, the voltage output of thesecond sensor 22401 is sufficient to change thesecond switch 22405 between a closed state and an open state. When both switches 22405' and 22405 are in an open state, ground potential is applied to theoperational amplifier circuit 22406. Theoperational amplifier circuit 22406 is in signal communication with the input channel of themicrocontroller 22490 of the motor controller, and when the ground potential is applied to theoperational amplifier circuit 22406, themicrocontroller 22490 receives the ground signal from thecircuit 22406.

当微控制器22490从电路22406接收接地信号时，微控制器22490可以确定钉击发冲程已经完成并且定位在缝合组件22400中的钉仓已经完全用完。设想了其它实施方案，其中传感器系统被构造成检测钉击发构件22460的部分击发冲程并向微控制器22490供应指示钉仓已经至少部分用完的信号。在任一种情况下，马达控制器可以构造成防止击发构件22460执行另一击发冲程，直到已经用未用完的钉仓替换钉仓。在至少一种情况下，除上述之外，传感器系统包括传感器，该传感器被构造成检测用完的仓是否已经从缝合组件拆卸和/或未用完的仓是否已经组装到缝合组件。When themicrocontroller 22490 receives the ground signal from thecircuit 22406, themicrocontroller 22490 can determine that the staple firing stroke has been completed and that the staple cartridge positioned in the staplingassembly 22400 has been completely depleted. Other embodiments are contemplated in which the sensor system is configured to detect a partial firing stroke of thestaple firing member 22460 and supply a signal to themicrocontroller 22490 indicating that the staple cartridge has been at least partially depleted. In either case, the motor controller can be configured to prevent the firingmember 22460 from performing another firing stroke until the staple cartridge has been replaced with an unused staple cartridge. In at least one instance, in addition to the above, the sensor system includes a sensor configured to detect whether a spent cartridge has been disassembled from the suturing assembly and/or whether an unused cartridge has been assembled to the suturing assembly.

除上述之外，传感器系统可以被构造成检测击发构件22460是否已经沿缩回路径22462缩回。在至少一种情况下，当磁性元件22461沿路径22462缩回并且将第二开关22405改变回闭合状态时，传感器22401可以检测磁性元件22461。类似地，当磁性元件22461沿路径22463缩回并且将第一开关22405’改变回闭合状态时，传感器22401’可以检测磁性元件22461。通过闭合开关22405和22405’，来自电池22403的电压极性被施加到电路22406并且因此，微处理器22490在其输入通道上从电路22406接收Vcc信号。在各种情况下，马达控制器可以构造成防止电动马达被操作执行另一个钉击发冲程，直到击发构件22460已经完全缩回。In addition to the above, the sensor system may be configured to detect whether the firingmember 22460 has been retracted along theretraction path 22462. In at least one instance, thesensor 22401 can detect themagnetic element 22461 when themagnetic element 22461 is retracted along thepath 22462 and thesecond switch 22405 is changed back to a closed state. Similarly, sensor 22401' can detectmagnetic element 22461 whenmagnetic element 22461 retracts alongpath 22463 and changes first switch 22405' back to a closed state. By closingswitches 22405 and 22405', the voltage polarity frombattery 22403 is applied tocircuit 22406 and thus,microprocessor 22490 receives the Vcc signal fromcircuit 22406 on its input channel. In various cases, the motor controller may be configured to prevent the electric motor from being operated to perform another staple firing stroke until the firingmember 22460 has been fully retracted.

在图71至图74中示出了包括钉仓25730、击发构件25760和闭锁件25780的缝合组件25700。钉仓25730包括滑动件25770，该滑动件25770在击发构件25760的钉击发冲程期间被击发构件25760向远侧推动。在钉击发冲程期间，击发构件25760将滑动件25770从近侧未击发位置(图71和图72)向远侧推向远侧击发位置(图73和图74)。滑动件25770被构造成在可移除地存储在钉腔体(其限定在钉仓25730中)中的钉下方滑动，并从钉腔体射出钉。在各种情况下，钉仓25730包括钉驱动器，钉驱动器其一支撑钉仓中的钉，并且其二由滑动件25770驱动以从钉腔体射出钉。在击发构件25760的钉击发冲程完成之后，击发构件25760向近侧缩回。值得注意的是，滑动件25770不会与击发构件25760一起向近侧缩回。A staplingassembly 25700 including astaple cartridge 25730, a firingmember 25760, and alatch 25780 is shown in FIGS. 71-74. Thestaple cartridge 25730 includes aslider 25770 that is pushed distally by the firingmember 25760 during the staple firing stroke of the firingmember 25760. During the staple firing stroke, the firingmember 25760 pushes theslider 25770 distally from the proximal unfired position (FIGS. 71 and 72) to the distal fired position (FIGS. 73 and 74).Slider 25770 is configured to slide under staples removably stored in staple cavities (defined in staple cartridge 25730) and eject staples from the staple cavities. In various cases, thestaple cartridge 25730 includes a staple driver, one of which supports the staples in the staple cartridge, and the other of which is driven by theslider 25770 to eject the staples from the staple cavity. After the staple firing stroke of the firingmember 25760 is complete, the firingmember 25760 is retracted proximally. Notably, theslider 25770 does not retract proximally with the firingmember 25760.

除上述之外，闭锁件25780包括锁定臂25782。每个锁定臂25782包括悬臂梁，该悬臂梁包括安装到缝合组件25700的轴的第一端部和被构造成接合击发构件25760的可移动的第二端部。击发构件25760包括限定在击发构件中的锁定孔隙25762，该锁定孔隙25762被构造成接收锁定臂25782的第二端部。然而，当滑动件25770处于其近侧未击发位置时(图71和图72)，滑动件25770使锁定臂25782侧向偏离击发构件25760并将锁定臂25782保持脱出锁定孔隙25762。因此，当钉仓25730定位在缝合组件25700中并且钉仓25730的滑动件25770处于其未击发位置时，闭锁件25780不防止击发构件25760执行钉击发冲程。当击发构件25760在其钉击发冲程期间向远侧推进时，限定在击发构件25760中的锁定孔隙25762不再与锁定臂25782对准，因此，一旦开始则锁定臂25782不会中断钉击发冲程。在击发构件25760的钉击发冲程之后，击发构件25760向近侧缩回到其未击发位置，如图73和图74所示。此时，锁定孔隙25762与锁定臂25782重新对准，并且当滑动件25770未返回其未击发位置时，锁定臂25782可以进入到锁定孔隙25762中并闭锁击发构件25760。In addition to the above, thelatch 25780 includes alocking arm 25782. Each lockingarm 25782 includes a cantilever beam including a first end mounted to the shaft of thesuture assembly 25700 and a movable second end configured to engage the firingmember 25760. The firingmember 25760 includes a lockingaperture 25762 defined in the firing member that is configured to receive the second end of thelocking arm 25782. However, when theslider 25770 is in its proximal unfired position ( FIGS. 71 and 72 ), theslider 25770 deflects thelocking arm 25782 laterally from the firingmember 25760 and retains thelocking arm 25782 out of the lockingaperture 25762 . Thus, when thestaple cartridge 25730 is positioned in the staplingassembly 25700 and thesled 25770 of thestaple cartridge 25730 is in its unfired position, thelatch 25780 does not prevent the firingmember 25760 from performing the staple firing stroke. When the firingmember 25760 is advanced distally during its staple firing stroke, the lockingapertures 25762 defined in the firingmember 25760 are no longer aligned with the lockingarms 25782, so the lockingarms 25782 do not interrupt the staple firing stroke once initiated. After the staple firing stroke of the firingmember 25760, the firingmember 25760 is retracted proximally to its unfired position, as shown in FIGS. 73 and 74 . At this point, the lockingaperture 25762 is realigned with the lockingarm 25782, and when theslider 25770 does not return to its unfired position, the lockingarm 25782 can enter the lockingaperture 25762 and latch the firingmember 25760.

因此，闭锁件25780包括缺失的仓闭锁件和用完的仓闭锁件。设想了另选的实施方案，其中钉仓25730不能够从缝合组件25700移除。在此类实施方案中，闭锁件25780将包括用完的仓闭锁件。Thus, thelatch 25780 includes a missing bin latch and a spent bin latch. Alternative embodiments are contemplated in which thestaple cartridge 25730 is not removable from the staplingassembly 25700. In such embodiments, thelatch 25780 would include a spent cartridge latch.

参考图75和图76，缝合组件25800包括钉仓25830，该钉仓25830包括仓主体25831、能够在仓主体25831内向远侧移动的滑动件25870，以及钉驱动器25880。仓主体包括限定在仓主体中的钉腔体25832和可移除地存储在钉腔体25832中的钉。在钉击发冲程期间，滑动件25870可在近侧未击发位置(图75)和远侧击发位置之间向远侧平移。在钉击发冲程期间，滑动件25870接触钉驱动器25880并在钉腔体25832内向上驱动钉驱动器25880，如图76所示。值得注意的是，仓主体25831包括限定在仓主体中的若干纵向排钉腔体25832，并且钉驱动器25880布置成纵向排，其与纵向排钉腔体25832对准。在滑动件25870的钉击发冲程期间，当滑动件25870向远侧推进时，钉驱动器25880和钉被按顺序驱动。换言之，在最远侧驱动器25880和钉被击发之前，最近侧钉驱动器25880和钉被击发。在各种情况下，最近侧钉驱动器25880的击发标志着钉击发冲程的开始。75 and 76, the staplingassembly 25800 includes astaple cartridge 25830 that includes acartridge body 25831, aslider 25870 that can move distally within thecartridge body 25831, and astaple driver 25880. The cartridge body includesstaple cavities 25832 defined in the cartridge body and staples removably stored in thestaple cavities 25832. During the staple firing stroke, theslider 25870 can translate distally between a proximal unfired position (FIG. 75) and a distal fired position. During the staple firing stroke, theslider 25870 contacts thestaple drivers 25880 and drives thestaple drivers 25880 upwardly within thestaple cavity 25832, as shown in FIG. 76 . Notably, thecartridge body 25831 includes several longitudinal rows ofstaple cavities 25832 defined in the cartridge body, and thestaple drivers 25880 are arranged in longitudinal rows that are aligned with the longitudinal rows ofstaple cavities 25832. During the staple firing stroke of thesled 25870, as thesled 25870 is advanced distally, thestaple driver 25880 and staples are driven sequentially. In other words, the proximal-moststaple drivers 25880 and staples are fired before thedistal-most drivers 25880 and staples are fired. In each case, the firing of the nearestside staple driver 25880 marks the start of the staple firing stroke.

再次参考图75和图76，钉仓25830包括闭锁电路，该闭锁电路被构造成检测钉仓25830何时至少部分地被击发。闭锁电路的一部分延伸通过仓主体25831并包括电接触件25834。闭锁电路的另一部分延伸通过最近侧钉驱动器25880并包括与电接触件25834对准的电接触件25884。当钉仓25830处于其未击发状态时(图75)，驱动器接触件25884邻接仓主体接触件25834，并且因此，闭锁电路处于闭合状态。当最近侧钉驱动器25880被滑动件25870向上提升时，驱动器接触件25884与仓主体接触件25834脱离并且闭锁电路打开。闭锁电路与缝合组件25800的控制器进行信号通信，该控制器被构造成解释闭锁电路的打开意味着缝合组件25800中的钉仓25830已经至少部分地被击发并且在没有用未用完的钉仓25830替换钉仓25830的情况下，不应该操作钉击发系统第二或额外的时间。一旦未用完的钉仓25830已经定位在缝合组件25800中并且闭锁电路被未用完的钉仓25830别和，则控制器可以准许钉击发系统再次操作。Referring again to Figures 75 and 76, thestaple cartridge 25830 includes a latching circuit configured to detect when thestaple cartridge 25830 is at least partially fired. A portion of the latching circuit extends through thecartridge body 25831 and includeselectrical contacts 25834. Another portion of the latching circuit extends through the proximal-moststaple driver 25880 and includeselectrical contacts 25884 that align withelectrical contacts 25834. When thestaple cartridge 25830 is in its unfired state (FIG. 75), thedriver contact 25884 abuts thecartridge body contact 25834, and thus, the latch circuit is closed. When the proximal-moststaple driver 25880 is lifted up by theslider 25870, thedriver contacts 25884 disengage from thecartridge body contacts 25834 and the latch circuit opens. The latching circuit is in signal communication with a controller of the staplingassembly 25800, the controller being configured to interpret that the opening of the latching circuit means that thestaple cartridge 25830 in the staplingassembly 25800 has been at least partially fired and is not using the unused staple cartridge. With the 25830 replacing thestaple cartridge 25830, the staple firing system should not be operated for a second or additional time. Once theunused staple cartridge 25830 has been positioned in the staplingassembly 25800 and the latch circuit has been deactivated by theunused staple cartridge 25830, the controller may permit the staple firing system to operate again.

在各种情况下，再次参考图76，最近侧钉驱动器25880与钉腔体25832的侧壁略微摩擦配合接合。因此，最近侧钉驱动器25880在被滑动件25870向上提升之后保持在其击发位置，并且因此，一旦闭锁电路打开并且闭锁电路重新闭合的可能性降低，则驱动器接触件25884保持脱出与仓主体接触件25834接触。In each case, referring again to FIG. 76 , the proximalproximal staple driver 25880 engages the sidewall of thestaple cavity 25832 with a slight friction fit. Therefore, the proximal-moststaple driver 25880 remains in its fired position after being lifted up by theslide 25870, and thus, thedriver contacts 25884 remain disengaged from the cartridge body contacts once the latch circuit is open and less likely to re-close 25834 Contact.

如上所述，钉仓25830的钉击发冲程打开闭锁电路。在另选实施方案中，钉仓的钉击发冲程可以闭合闭锁电路。在此类实施方案中，缝合组件的控制器可以解释闭锁电路的闭合意味着钉仓已经至少部分地被击发，并且在没有用未用完的钉仓替换钉仓的情况下，不应该操作钉击发系统第二或额外的时间。As described above, the staple firing stroke of thestaple cartridge 25830 opens the latching circuit. In alternative embodiments, the staple firing stroke of the staple cartridge may close the latching circuit. In such embodiments, the controller of the stapling assembly may interpret the closure of the latch circuit to mean that the staple cartridge has been at least partially fired, and that the staples should not be manipulated without replacing the staple cartridge with an unused staple cartridge Firing the system for a second or extra time.

除了上述之外或代替上述内容，缝合组件可以包括检测电路，该检测电路被构造成检测何时最远侧钉驱动器25880和钉已经被击发。在至少一个此种情况下，最远侧钉驱动器25880可以具有上述接触布置，和/或任何其它合适的布置，其改变检测电路的状态。比如，缝合组件的控制器可以解释检测电路的状态变化意味着钉仓已经完全击发并且钉击发系统应该缩回。In addition to or in lieu of the above, the stapling assembly may include detection circuitry configured to detect when the distal-moststaple driver 25880 and staples have been fired. In at least one such case, the distal-moststaple driver 25880 may have the contact arrangement described above, and/or any other suitable arrangement that changes the state of the detection circuit. For example, the controller of the suturing assembly can interpret a change in state of the detection circuit to mean that the staple cartridge has been fully fired and that the staple firing system should be retracted.

现在转到图77和图78，缝合组件25900包括轴25910、砧座夹具25920和钉仓夹具，该钉仓夹具可移除地附接到轴25910的框架。缝合组件25900还包括关节运动接头25940，该关节运动接头25940被构造成准许砧座夹具25920和钉仓夹具相对于轴25910进行关节运动。类似于本文所述的实施方案，钉仓夹具能够在打开位置和闭合位置之间运动，以将患者的组织抵靠砧座夹具25920夹紧。Turning now to FIGS. 77 and 78 , the staplingassembly 25900 includes ashaft 25910 , ananvil clamp 25920 , and a staple cartridge clamp that is removably attached to the frame of theshaft 25910 . The staplingassembly 25900 also includes an articulation joint 25940 configured to permit articulation of theanvil clamp 25920 and the cartridge clamp relative to theshaft 25910. Similar to the embodiments described herein, the cartridge clamp is movable between an open position and a closed position to clamp the patient's tissue against theanvil clamp 25920.

缝合组件25900还包括闭锁电路25980，该闭锁电路25980被构造成检测钉仓夹具何时处于其闭合位置。闭锁电路25980包括延伸通过轴25910的导体25984和位于砧座夹具25920中的电极垫25982。导体25984将电极垫25982放置成与钉组件25900的控制器通信，并且在各种情况下，控制器可以在导体25984上施加电压电位以在闭锁电路25980内产生监控电流。如下面更详细描述的，控制器被构造成评估闭锁电路25980的阻抗和/或电阻率，并且经由监测电流来监测闭锁电路25980的阻抗和/或电阻率的变化。The staplingassembly 25900 also includes alatching circuit 25980 that is configured to detect when the cartridge clamp is in its closed position.Latch circuit 25980 includesconductors 25984 extending throughshaft 25910 andelectrode pads 25982 located inanvil clamp 25920. Theconductors 25984 place theelectrode pads 25982 in communication with the controller of thestaple assembly 25900, and in various cases, the controller can apply a voltage potential on theconductors 25984 to generate a monitoring current within the latchingcircuit 25980. As described in more detail below, the controller is configured to evaluate the impedance and/or resistivity of the latchingcircuit 25980, and monitor changes in the impedance and/or resistivity of the latchingcircuit 25980 via monitoring the current.

除上述之外，主要参考图78，钉仓夹具包括销25932，该销25932被构造成在钉仓夹具移动到其闭合位置时刺穿和/或变形电极垫25982。销25932例如由不锈钢构成，并且破坏由控制器检测到的闭锁电路25980的阻抗和/或电阻率。此种破坏可以通知控制器其一，钉仓已经附接到缝合组件25900，并且其二，钉仓夹具已经闭合。此时，控制器可以电子地解锁钉击发系统并准许钉击发系统执行其钉击发冲程。在至少一个此种情况下，钉击发系统包括电动马达和电池，其中控制器包括电子或软件闭锁件，其防止电池向电动马达提供足够的电力执行钉击发冲程，直到控制器检测到闭锁电路25980的参数已经发生了充分变化。因此，钉仓组件25900的钉击发系统不能操作，直到钉仓夹具已经闭合。78, the staple cartridge clamp includes apin 25932 configured to pierce and/or deform theelectrode pad 25982 when the staple cartridge clamp is moved to its closed position. Thepin 25932 is constructed of stainless steel, for example, and disrupts the impedance and/or resistivity of the latchingcircuit 25980 as detected by the controller. Such a breach can notify the controller that, on the one hand, the staple cartridge has been attached to the staplingassembly 25900, and on the other hand, the staple cartridge clamp has been closed. At this point, the controller may electronically unlock the staple firing system and permit the staple firing system to perform its staple firing stroke. In at least one such case, the staple firing system includes an electric motor and a battery, wherein the controller includes an electronic or software latch that prevents the battery from providing sufficient power to the electric motor to perform the staple firing stroke until the controller detects thelatch circuit 25980 parameters have changed sufficiently. Therefore, the staple firing system of thestaple cartridge assembly 25900 cannot operate until the staple cartridge clamps have been closed.

再次参考图77，闭锁电路25980延伸通过轴25910和砧座夹具25920，但不延伸通过钉仓夹具。虽然钉仓夹具的销25932破坏闭锁电路25980，如上所述，但销25932在钉仓夹具内电绝缘并且不闭合或打开闭锁电路25980。Referring again to Figure 77, thelatch circuit 25980 extends through theshaft 25910 and theanvil clamp 25920, but not through the cartridge clamp. Although thepins 25932 of the cartridge clamp break thelatch circuit 25980, as described above, thepins 25932 are electrically isolated within the cartridge clamp and do not close or open thelatch circuit 25980.

另选地，再次参考图77和图78，销25932是闭锁电路25980的零件，电极垫25982包括由销25932刺穿的接触件。在此类实施方案中，当销25932接合电极垫25982时，销25932闭合闭锁电路，使得感测电流可以在销25932和电极垫25982之间流动。在至少一种情况下，电极垫25982可以例如由自修复材料，诸如导电凝胶构成。在各种情况下，销25932可在进入到电极垫25982中之前刺穿组织。再次参考图77，电极垫25982可以包括擦拭垫25983，该擦拭垫25983被构造成在销25932进入电极垫25982之前至少部分地清洁销25932。Alternatively, referring again to FIGS. 77 and 78 , thepins 25932 are part of the latchingcircuit 25980 and theelectrode pads 25982 include contacts pierced by thepins 25932 . In such embodiments, when thepin 25932 engages theelectrode pad 25982, thepin 25932 closes the latching circuit so that sense current can flow between thepin 25932 and theelectrode pad 25982. In at least one instance, theelectrode pads 25982 can be composed of, for example, a self-healing material, such as a conductive gel. In various cases, thepins 25932 can pierce tissue prior to entering theelectrode pads 25982. Referring again to FIG. 77 , theelectrode pads 25982 can includewiper pads 25983 configured to at least partially clean thepins 25932 before they enter theelectrode pads 25982 .

参考图79和图80，轴25910包括外壳体25911，该外壳体25911包括限定在外壳体中的纵向狭槽25912，该纵向狭槽25912被构造成可滑动地接收击发构件25960。纵向狭槽25912延伸通过关节运动接头25940并进入砧座夹具25920和钉仓夹具。当砧座夹具25920和钉仓夹具处于非关节运动取向时，纵向狭槽25912是直的，或不包括方向变化。当砧座夹具25920和钉仓夹具处于关节运动取向时，纵向狭槽25912包括方向变化。因此，击发构件25960需要足够柔性以穿过关节运动接头25940。然而，击发构件25960的此种柔性可促使击发构件25960在钉击发冲程期间屈曲。为了防止或减少此种屈曲，缝合组件25900还包括定位在击发构件25960的相对侧上的防屈曲或防爆板25944，其被构造成在关节运动接头25940内和/或邻近关节运动接头25940支撑击发构件25960。在至少一种情况下，防屈曲板25944相对于关节运动接头25940定位在轴25910中的近侧。79 and 80, theshaft 25910 includes anouter housing 25911 that includes alongitudinal slot 25912 defined in the outer housing that is configured to slidably receive the firingmember 25960. Thelongitudinal slot 25912 extends through the articulation joint 25940 and into theanvil clamp 25920 and cartridge clamp. When theanvil clamp 25920 and cartridge clamp are in the non-articulating orientation, thelongitudinal slot 25912 is straight, or does not include a change in direction. Thelongitudinal slot 25912 includes a change in orientation when theanvil clamp 25920 and cartridge clamp are in the articulating orientation. Therefore, the firingmember 25960 needs to be flexible enough to pass through thearticulation joint 25940. However, such flexibility of the firingmember 25960 may cause the firingmember 25960 to flex during the staple firing stroke. To prevent or reduce such buckling, suturingassembly 25900 also includes anti-buckling or burstplates 25944 positioned on opposite sides of firingmember 25960 that are configured to support firing within and/or adjacent articulation joint 25940Member 25960. In at least one instance, theanti-flexion plate 25944 is positioned proximally in theshaft 25910 relative to thearticulation joint 25940.

除上述之外，轴25910和关节运动接头25940包括限定在其中的布线通道，该布线通道被构造成接收闭锁电路25980的导体25984。比如，轴25910包括限定在轴25910的外壳体25911中的通道25915。在至少一个此种情况下，第一导体25984延伸通过第一通道25915，并且第二导体25984延伸通过第二通道25915。此外，每个防屈曲板25984包括限定在防屈曲板中的通道25945，该通道25945被构造成接收导体25984。通道25945与通道25915对准或至少基本上对准。In addition to the above,shaft 25910 and articulation joint 25940 include routing channels defined therein that are configured to receiveconductors 25984 oflatch circuit 25980. For example, theshaft 25910 includes achannel 25915 defined in theouter housing 25911 of theshaft 25910. In at least one such instance, thefirst conductor 25984 extends through thefirst channel 25915 and thesecond conductor 25984 extends through thesecond channel 25915. Additionally, each bucklingprevention plate 25984 includes achannel 25945 defined in the buckling prevention plate, thechannel 25945 being configured to receive aconductor 25984.Channel 25945 is aligned or at least substantially aligned withchannel 25915.

参考图81，钉仓26230包括纵向狭槽26231和限定在钉仓中的纵向排钉腔体26232。在钉击发冲程期间，例如击发构件，诸如击发构件25960，被构造成在纵向狭槽26231内滑动以向远侧推动例如滑动件，诸如滑动件25770，以将钉从钉腔体26232射出。与上述类似，击发构件25960和滑动件25770从钉腔体26232按顺序射出钉，并且因此例如抵靠砧座，诸如砧座25920使钉按顺序顺序变形。通过击发构件25960传递以按顺序使钉变形的推力很少(如果有的话)是恒定的。相反，推力通常包括一系列峰值，这些峰值与抵靠砧座变形的钉重合。图81A示出了此类力峰值。更具体地，图81A示出了击发构件25960在钉击发冲程的长度(L)上经历的推力(F)的典型力曲线26260。力曲线26260包括峰26261和峰26261之间的谷26262。81, thestaple cartridge 26230 includes alongitudinal slot 26231 and a longitudinal row ofstaple cavities 26232 defined in the staple cartridge. During the staple firing stroke, eg, a firing member, such as firingmember 25960, is configured to slide withinlongitudinal slot 26231 to push distally, eg, a slider, such asslider 25770, to eject staples fromstaple cavity 26232. Similar to the above, the firingmember 25960 andslider 25770 sequentially fire the staples from thestaple cavity 26232 and thus deform the staples in a sequential order against an anvil, such as theanvil 25920, for example. The thrust transmitted by the firingmember 25960 to sequentially deform the staples is rarely, if ever, constant. Instead, the thrust typically includes a series of peaks that coincide with the staple deforming against the anvil. Figure 81A shows such force peaks. More specifically, Figure 81A shows atypical force curve 26260 for the thrust force (F) experienced by the firingmember 25960 over the length (L) of the staple firing stroke. Theforce curve 26260 includes apeak 26261 and avalley 26262 between thepeaks 26261.

在各种情况下，除上述之外，缝合组件的控制器可以构造成监测施加到击发构件25960的推力。在至少一种情况下，钉击发系统包括构造成驱动击发构件25960的电动马达，并且在此类情况下，可以监测在钉击发冲程期间由电动马达汲取的电流，作为施加到击发构件25960的推力的指标。事实上，比较由电动马达经钉击发冲程汲取的电流的图表可能看起来非常类似于图81A中所示的力曲线26260。在某些实施方案中，力传感器可用于监测推力。在任何情况下，控制器可以在击发冲程期间对力曲线26260的峰值26261进行计数，并且在已经达到预先确定的计数阈值之后停止钉击发冲程。在至少一个此种情况下，钉仓可以包括可移除地存储在钉仓中的100个钉，并且在控制器已经计数100个力和/或电流峰值之后，例如，当可以假设钉击发冲程已经完成时，控制器可以中断对电动马达的供电。In various cases, in addition to the above, the controller of the suturing assembly may be configured to monitor the thrust force applied to the firingmember 25960. In at least one instance, the staple firing system includes an electric motor configured to drive the firingmember 25960, and in such instances, the current drawn by the electric motor during the staple firing stroke can be monitored as the thrust applied to the firingmember 25960 index of. In fact, a graph comparing the current drawn by an electric motor through a nail firing stroke may look very similar to theforce curve 26260 shown in Figure 81A. In certain embodiments, force sensors may be used to monitor thrust. In any event, the controller may countpeaks 26261 of theforce curve 26260 during the firing stroke and stop the staple firing stroke after a predetermined count threshold has been reached. In at least one such case, the staple cartridge may include 100 staples removably stored in the staple cartridge, and after the controller has counted 100 force and/or current peaks, eg, when a staple firing stroke can be assumed When this has been done, the controller may interrupt power to the electric motor.

在各种情况下，除上述之外，缝合组件可以被构造成与钉仓一起使用，该钉仓具有不同长度和/或存储在钉仓中的不同数量的钉。例如，缝合组件可与第一钉仓和第二钉仓一起使用，该第一钉仓被构造成施加大约45mm的钉线，该第二钉仓被构造成施加大约60mm的钉线。第一钉仓包括可移除地存储在第一钉仓中的第一数量的钉，并且第二钉仓包括可移除地存储在第二钉仓中的第二数量的钉，该第二数量大于第一数量。当第一钉仓与缝合组件一起使用时，控制器被构造成在控制器识别出第一数量的力峰值之后停止钉击发冲程，并且类似地，当第二钉仓与缝合组件一起使用时，控制器被构造成在控制器识别出第二数量的力峰值之后停止钉击发冲程。换句话说，控制器可以构造成评估第一仓的力曲线，例如诸如力曲线26260，以及第二仓的力曲线，例如诸如力曲线26260’。此外，控制器可以被构造成监测任何合适数量的钉仓的力曲线。In various cases, in addition to the above, the stapling assembly may be configured for use with staple cartridges having different lengths and/or different numbers of staples stored in the staple cartridge. For example, a stapling assembly can be used with a first staple cartridge configured to apply approximately 45 mm of staple line and a second staple cartridge configured to apply approximately 60 mm of staple line. The first staple cartridge includes a first quantity of staples removably stored in the first staple cartridge, and the second staple cartridge includes a second quantity of staples removably stored in the second staple cartridge, the second staple cartridge The quantity is greater than the first quantity. When the first staple cartridge is used with the stapling assembly, the controller is configured to stop the staple firing stroke after the controller identifies the first number of force peaks, and similarly, when the second staple cartridge is used with the stapling assembly, The controller is configured to stop the nail firing stroke after the controller identifies the second number of force peaks. In other words, the controller may be configured to evaluate the force profile of the first bin, such asforce profile 26260, for example, and the force profile of the second bin, eg, force profile 26260'. Additionally, the controller may be configured to monitor the force profile of any suitable number of staple cartridges.

除上述之外，可以与缝合组件一起使用的钉仓可以包括唯一的标识符，其可以辅助缝合组件的控制器识别附接到缝合组件的钉仓的类型。在至少一种情况下，钉仓具有唯一的RFID标签，其例如可以与缝合组件的控制器通信。在某些情况下，钉仓上具有条形码，这些条形码例如在与缝合组件一起使用之前可以被扫描。一旦控制器识别附接到缝合组件的钉仓的类型，控制器就可以确定钉击发冲程的适当长度。在至少一种情况下，关于钉仓的适当击发冲程长度的信息可以存储在例如与控制器的微处理器通信的存储设备中。In addition to the above, a staple cartridge that can be used with a stapling assembly can include a unique identifier that can assist a controller of the stapling assembly to identify the type of staple cartridge attached to the stapling assembly. In at least one instance, the staple cartridge has a unique RFID tag that can communicate with, for example, a controller of the stapling assembly. In some cases, the staple cartridge has barcodes on it that can be scanned, for example, prior to use with the stapling assembly. Once the controller identifies the type of staple cartridge attached to the stapling assembly, the controller can determine the appropriate length of the staple firing stroke. In at least one instance, information regarding the appropriate firing stroke length of the staple cartridge may be stored, for example, in a memory device in communication with a microprocessor of the controller.

除了上述之外或代替上述内容，钉仓，例如诸如钉仓26230可以被构造成在推力中产生可检测的力峰值和/或在钉击发冲程结束时产生电动马达汲取的电流峰值。参考图81，钉仓26230包括一个或多个牙桥26233，该牙桥26233在纵向狭槽26231的远侧端部附近，即在钉击发冲程的远侧端部附近横跨纵向狭槽26231延伸。当击发构件26260向远侧推进时，击发构件26260接触牙桥26233并且断开和/或切入桥26233，这在推力和/或供应电流中产生峰值，该峰值与钉变形时产生的峰值不同。在至少一种情况下，通过使牙桥26233失效而产生的峰值比通过使钉变形而产生的峰值大得多，并且控制器被构造成辨别此类峰值中的差异。一旦控制器识别出牙桥已经产生某些峰值，控制器就可以停止钉击发冲程。如读者应该理解的，此类布置将允许控制器在适当的时刻停止钉击发系统，而不管例如附接到缝合组件的钉仓的长度和/或存储在钉仓中的钉的数量如何。In addition to or in lieu of the above, a staple cartridge, such asstaple cartridge 26230, for example, may be configured to produce a detectable peak in force in thrust and/or a peak in current drawn by an electric motor at the end of the staple firing stroke. Referring to Figure 81, thestaple cartridge 26230 includes one ormore bridges 26233 extending across thelongitudinal slot 26231 near the distal end of thelongitudinal slot 26231, ie near the distal end of the staple firing stroke . When the firingmember 26260 is advanced distally, the firingmember 26260 contacts thebridge 26233 and breaks and/or cuts into thebridge 26233, which produces a peak in thrust and/or supply current that is different from the peak produced when the staple is deformed. In at least one instance, the peaks produced by deactivating thebridge 26233 are substantially larger than the peaks produced by deforming the staples, and the controller is configured to discern the difference in such peaks. Once the controller recognizes that the bridge has produced certain peaks, the controller can stop the nail firing stroke. As the reader will appreciate, such an arrangement would allow the controller to stop the staple firing system at the appropriate time, regardless of, for example, the length of the staple cartridge attached to the stapling assembly and/or the number of staples stored in the staple cartridge.
