技术领域technical field
本发明涉及医疗器械技术领域，尤其涉及吻合器技术领域，具体涉及一种把手组件及包括其的吻合器。The present invention relates to the technical field of medical devices, in particular to the technical field of staplers, and in particular to a handle assembly and a stapler including the same.
背景技术Background technique
消化道肿瘤是人类高发的疾病之一，在治疗过程中，常使用圆管型吻合器代替医生的手工操作对消化道等生理组织进行吻合。圆管型吻合器是一种常见的外科手术器械，大多采用轴向内装订方式，在手术时对食管、胃、肠道等生理组织形成端对端的、或者端对侧的吻合，吻合时两段组织内敛收容于吻合器内，击发完成后在组织上形成圆形吻合口，重建了组织通道。Digestive tract tumors are one of the most common diseases in human beings. In the course of treatment, circular anastomoses are often used to perform anastomosis on physiological tissues such as the digestive tract instead of the manual operation of doctors. The tubular stapler is a common surgical instrument, most of which use axial inward binding to form end-to-end or end-to-side anastomosis on physiological tissues such as esophagus, stomach, and intestine during surgery. The segmental tissue is restrained and accommodated in the stapler, and after the firing is completed, a circular anastomosis is formed on the tissue, and the tissue channel is reconstructed.
现有技术中，圆管型吻合器包括吻合器本体、活动连接所述吻合器本体的把手组件以及与所述本体配合的钉砧组件。所述吻合器本体包括设于远端的钉仓组件，所述钉仓组件包括环形钉仓、切刀；以及设于本体近端的旋钮，所述旋钮可相对于本体旋转。此处远端和近端是相对于操作者来说的，距离操作者较近的一端为近端，距离操作者较远的一端，即更靠近手术位置的一端为远端。所述钉砧组件包括钉砧、设置在钉砧顶部的钉砧帽、设置在钉砧内部的刀砧，以及与吻合器本体可拆卸地连接的钉砧轴。在手术过程中，离断去除肿瘤组织后，钉砧轴从组织一端的荷包穿出，配置于吻合器本体的远端，旋转旋钮，使钉砧和钉仓之间的距离逐渐减小达到一个合适的距离后，达到可击发状态，才能握持把手击发器械完成吻合。随着医疗器械的不断发展，圆管型吻合器也越来越广泛地应用于痔疮等疾病的治疗。In the prior art, a cylindrical stapler includes a stapler body, a handle assembly movably connected to the stapler body, and an anvil assembly that cooperates with the body. The stapler body includes a staple cartridge assembly disposed at the distal end, the staple cartridge assembly including an annular staple cartridge, a cutter; and a knob disposed at the proximal end of the body, the knob being rotatable relative to the body. The distal end and the proximal end here are relative to the operator, the end closer to the operator is the proximal end, and the end farther away from the operator, that is, the end closer to the surgical site is the distal end. The anvil assembly includes an anvil, an anvil cap disposed on the top of the anvil, an anvil disposed inside the anvil, and an anvil shaft detachably connected with the stapler body. During the operation, after the tumor tissue is cut off and removed, the anvil shaft passes through the purse at one end of the tissue, and is arranged at the distal end of the stapler body. Rotate the knob to gradually reduce the distance between the anvil and the staple cartridge to a After a suitable distance is reached, the firing state is reached, and the handle can be held to complete the anastomosis. With the continuous development of medical devices, tubular staplers are also more and more widely used in the treatment of hemorrhoids and other diseases.
同时，在泌尿外科领域治疗包皮过长及包茎的手术中，也出现了另外一种形式的圆管型吻合器，即包皮吻合器。包皮吻合器在现有技术中也有描述，其结构类似于上述的消化道圆管型吻合器，区别仅在于与所述本体配合的是龟头帽组件。相似的，所述龟头帽组件包括钉砧、与钉砧固定连接的龟头帽、刀砧，以及与吻合器本体可拆卸地连接的中心杆。在手术过程中，把待切除的包皮组织固定在龟头帽上，然后把中心杆配置于吻合器本体的远端，旋转旋钮，使龟头帽与钉仓之间的距离逐渐减小达到一个合适的距离后，达到可击发状态，才能握持把手击发器械完成吻合。At the same time, in the field of urology, another form of cylindrical stapler, the prepuce stapler, has also appeared in the operation for the treatment of foreskin and phimosis. The foreskin stapler has also been described in the prior art, and its structure is similar to the above-mentioned alimentary canal round tube-type stapler, except that the glans cap component is matched with the body. Similarly, the glans cap assembly includes a nail anvil, a glans cap fixedly connected with the nail anvil, a knife anvil, and a center rod detachably connected with the stapler body. During the operation, the foreskin tissue to be removed is fixed on the glans cap, and then the central rod is arranged at the distal end of the stapler body, and the knob is rotated to gradually reduce the distance between the glans cap and the nail cartridge to a suitable After the distance is reached, the firing state is reached, and the handle can be held to complete the anastomosis.
随着技术的发展，人们已经对圆管型吻合器的击发传动机构进行了改进，增加了保险机制，在吻合器未达到可击发状态时，医生即使按动把手，由于保险机制的作用，把手也无法按动，从而避免了器械击发造成的手术失败。然而，实际情况下，仍然存在有一些缺陷，例如医生的使用体验不高，另外医生如果用力按动把手，可能会导致吻合器的机壳开裂。With the development of technology, people have improved the firing transmission mechanism of the cylindrical stapler and added a safety mechanism. When the stapler does not reach the firing state, even if the doctor presses the handle, due to the effect of the safety mechanism, the handle It also cannot be pressed, thus avoiding surgical failure caused by instrument firing. However, in practice, there are still some defects, for example, the doctor's use experience is not high, and if the doctor presses the handle forcefully, the casing of the stapler may crack.

具体实施方式Detailed ways
现在将参考附图更全面地描述示例实施方式。然而，示例实施方式能够以多种形式实施，且不应被理解为限于在此阐述的实施方式；相反，提供这些实施方式使得本发明将全面和完整，并将示例实施方式的构思全面地传达给本领域的技术人员。在图中相同的附图标记表示相同或类似的结构，因而将省略对它们的重复描述。Example embodiments will now be described more fully with reference to the accompanying drawings. Example embodiments, however, can be embodied in various forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the concept of example embodiments to those skilled in the art. The same reference numerals in the drawings denote the same or similar structures, and thus their repeated descriptions will be omitted.
如图1所示，为了实现上述目的，本发明一实施例提供一种把手组件，用于吻合器的击发，本发明将把手组件(图1中为清楚显示，省去把手组件的外壳)进行分段，分为第一把手1和第二把手2，并且只有当第二把手2旋转时才是可以击发吻合器的，并进一步设置控制第一把手1和第二把手2相对运动的指针4。其中：As shown in FIG. 1 , in order to achieve the above purpose, an embodiment of the present invention provides a handle assembly for firing a stapler. The segment is divided into a first handle 1 and a second handle 2, and the stapler can be fired only when the second handle 2 is rotated, and a pointer 4 for controlling the relative movement of the first handle 1 and the second handle 2 is further provided. in:
指针4设有第一端41、第二端42及固定端，指针4的第二端42与拉片的远端关联，拉片的近端套设于丝杆上，丝杆的近端与旋钮相连。旋转旋钮，可使拉片带动指针第二端42在第一位置区域和第二位置区域之间移动，其中在吻合器本体上对应于第一位置区域和第二位置区域处设有一视窗，用于观察指针第二端42在使用过程中所处的位置，指针第二端42在第一位置区域时，是处于保险状态的，此时吻合器不能击发，当指针第二端42处于第二位置区域时，吻合器可以击发，为了更直观地给医生以提示，在视窗上对应于可击发的第二位置区域L即为绿色区域，现有技术已经有揭示；The pointer 4 is provided with a first end 41, a second end 42 and a fixed end, the second end 42 of the pointer 4 is associated with the distal end of the pull tab, the proximal end of the pull tab is sleeved on the screw rod, and the proximal end of the screw rod is connected to the Knob is connected. Rotating the knob can make the pull tab drive the second end 42 of the pointer to move between the first position area and the second position area, wherein a viewing window is provided on the stapler body corresponding to the first position area and the second position area for using When observing the position of the second end 42 of the pointer during use, when the second end 42 of the pointer is in the first position area, it is in a safe state, and the stapler cannot be fired at this time. When the second end 42 of the pointer is in the second position In the position area, the stapler can be fired. In order to give the doctor a more intuitive prompt, the second position area L corresponding to the triggerable position on the window is the green area, which has been disclosed in the prior art;
第一把手1设置有滑槽17和滑块3，滑槽17包括相连通的第一段和第二段，滑块3可在滑槽17中移动；指针4的第二端42从第一位置区域移动至第二位置区域时，驱使滑块3从滑槽17的第一段向滑槽17的第二段移动；此处指针4驱使滑块3，指的是指针4直接推动(拉动)滑块3或间接推动(拉动)滑块，例如指针4和滑块3之间可以设置一个传动杆，或者是其他类型的传动机构，将指针4的移动传动至滑块3中，均属于本发明的保护范围之内。The first handle 1 is provided with a chute 17 and a slider 3. The chute 17 includes a first section and a second section that communicate with each other. The slider 3 can move in the chute 17; the second end 42 of the pointer 4 is located in the first position area When moving to the second position area, the slider 3 is driven to move from the first section of the chute 17 to the second section of the chute 17; here the pointer 4 drives the slider 3, which means that the pointer 4 directly pushes (pulls) the slider. Block 3 or indirectly pushes (pulls) the slider, for example, a transmission rod can be set between the pointer 4 and the slider 3, or other types of transmission mechanisms, to transmit the movement of the pointer 4 to the slider 3, all belong to the present invention within the scope of protection.
滑块3位于滑槽17的第一段，且第一把手1被握持而沿第一方向旋转时，滑块3在运动过程中不与第二把手2抵触，第二把手2处于保险位置；滑块3位于滑槽17的第二段，且滑槽17随第一把手1沿第一方向的旋转移动时，滑块3与第二把手2抵触并驱使第二把手2从保险位置向击发位置移动。在该实施例中，第一方向为图中的逆时针把手被握持的方向。When the slider 3 is located in the first section of the chute 17, and the first handle 1 is held and rotated in the first direction, the slider 3 does not interfere with the second handle 2 during the movement, and the second handle 2 is in the safe position; The slider 3 is located in the second section of the chute 17, and when the chute 17 rotates along the first direction with the first handle 1, the slider 3 collides with the second handle 2 and drives the second handle 2 from the safety position to the firing position move. In this embodiment, the first direction is the direction in which the handle is held counterclockwise in the figure.
指针4的第二端42在第一位置区域和第二位置区域时，第一把手1的运动对第二把手2造成的影响是不同的。指针4的第二端42在第一位置区域时，由于滑块3位于滑槽17的第一段，滑块3的运动过程不与第二把手2接触，也就不会对第二把手2产生作用力，第二把手2仍保持初始的保险状态，不会进行击发；指针4在第二位置区域时，由于滑块3处于滑槽17的第二段，第一把手1被握持而逆时针旋转的过程中，滑块3会带动第二把手2运动，并且将第二把手2推动到击发位置。因此，通过改变指针4的位置，即可以控制第一把手1和第二把手2的相互配合关系。When the second end 42 of the pointer 4 is in the first position area and the second position area, the influence of the movement of the first handle 1 on the second handle 2 is different. When the second end 42 of the pointer 4 is in the first position area, since the slider 3 is located in the first section of the chute 17 , the slider 3 does not contact the second handle 2 during the movement process, so it will not touch the second handle 2 . When a force is generated, the second handle 2 still maintains the initial safety state and will not be fired; when the pointer 4 is in the second position area, since the slider 3 is in the second section of the chute 17, the first handle 1 is held and reversed. During the rotation of the hour hand, the slider 3 will drive the second handle 2 to move, and push the second handle 2 to the firing position. Therefore, by changing the position of the pointer 4, the mutual cooperation between the first handle 1 and the second handle 2 can be controlled.
综上，在吻合器未做好击发准备时，指针4的第二端42是处在第一位置区域的，此时，医生握持第一把手1，可以轻易地使第一把手1旋转，但却不会触发第二把手2，因为此时是处于空击发状态，握持第一把手的力是非常小的。医生也可以通过此操作体验了解到当前吻合器处于非击发状态，并且不会造成吻合器的机壳破裂；在吻合器做好击发准备时，指针4是处在第二位置区域的，此时，医生握持第一把手1，第一把手1的运动会带动第二把手2的运动，进而驱动击发吻合器。To sum up, when the stapler is not ready for firing, the second end 42 of the pointer 4 is in the first position area. At this time, the doctor holds the first handle 1 and can easily rotate the first handle 1, but The second handle 2 will not be triggered, because it is in an empty firing state at this time, and the force for holding the first handle is very small. The doctor can also know that the current stapler is in a non-firing state through this operation experience, and the casing of the stapler will not be ruptured; when the stapler is ready to be fired, the pointer 4 is in the second position area, at this time , the doctor holds the first handle 1, and the movement of the first handle 1 will drive the movement of the second handle 2, thereby driving the firing stapler.
需要注意的是，本发明中所述滑槽17的第一段和第二段是一个相对概念，即在图中示出的视角中，滑槽17的第一段位于滑槽17的第二段右侧。It should be noted that the first and second sections of the chute 17 in the present invention are relative concepts, that is, in the perspective shown in the figure, the first section of the chute 17 is located at the second section of the chute 17 right side of the segment.
如图2所示，为本发明一实施例中把手组件应用于吻合器的结构示意图，该图中示出了一种圆管型吻合器。该吻合器的一端包括相互配合的钉仓组件52和钉砧组件53，另一端包括旋钮51和把手组件，第二把手2的第二端与一个推钉杆55的近端相配合。在吻合器满足击发条件时，第二把手推动推钉杆55，推钉杆55会进一步推动吻合器的推钉片和环形切刀，对进行手术的组织进行缝合和切割。此处图2示出的吻合器的结构仅为一种示例，在实际应用中，其他类型的吻合器也可以采用本发明实施例的把手组件，并且可以实现本发明的目的。例如，如图3所示，示出了应用该把手组件的包皮吻合器本体9的结构。包皮吻合器本体9的远端包括钉仓组件91，另外还设置有与钉仓组件91配合的龟头帽组件(图中未示出)。采用包皮吻合器时，第二把手2活动连接到包皮吻合器的一端，第二把手2的第二端与包皮吻合器的推钉部件相配合，当满足可击发条件时，第二把手2会推动推钉部件，实现包皮吻合器的击发。As shown in FIG. 2 , it is a schematic structural diagram of a handle assembly applied to a stapler in an embodiment of the present invention, and the figure shows a round tube-type stapler. One end of the stapler includes a mutually matched staple cartridge assembly 52 and an anvil assembly 53 , the other end includes a knob 51 and a handle assembly, and the second end of the second handle 2 is matched with the proximal end of a push rod 55 . When the stapler meets the firing conditions, the second handle pushes the pusher rod 55, and the pusher rod 55 further pushes the pusher blade and the annular cutter of the stapler to suture and cut the tissue to be operated on. The structure of the stapler shown in FIG. 2 here is only an example, and in practical applications, other types of staplers can also use the handle assembly of the embodiment of the present invention, and can achieve the purpose of the present invention. For example, as shown in FIG. 3, the structure of the foreskin stapler body 9 to which the handle assembly is applied is shown. The distal end of the foreskin stapler body 9 includes a staple cartridge assembly 91 , and is additionally provided with a glans cap assembly (not shown in the figure) matched with the staple cartridge assembly 91 . When the foreskin stapler is used, the second handle 2 is movably connected to one end of the foreskin stapler, and the second end of the second handle 2 is matched with the push-pin part of the foreskin stapler. When the triggerable condition is satisfied, the second handle 2 will Push the push nail part to achieve the firing of the foreskin stapler.
如图4所示，第一把手1的第一端11为握持部，供医生在手术时操作使用。第一把手1的第二端12可以通过第一销轴14与第二把手2的第一端21可旋转连接，第二把手2的第二端22可以通过第二销轴24与吻合器的壳体54可旋转连接。进一步地，第一把手1和第二把手2之间还设置有第一扭簧15，第一扭簧15套设于第一销轴14上，第二把手2和吻合器的壳体54之间还设置有第二扭簧25，第二扭簧25套设于第二销轴24上。因此，当滑块3位于滑槽17的第一段时，器械处于保险状态，第一把手1在受到操作者较小的握持力时，即可绕第一销轴14转动，且可以在外力解除时通过第一扭簧15沿顺时针方向恢复至初始位置，此时第二把手2不发生旋转。当滑块3在位于滑槽17的第二段时，第一把手1的转动会带动第二把手2的转动，使第二把手2绕第二销轴24转动，并且在外力解除时通过第二扭簧25沿顺时针方向恢复原状。As shown in FIG. 4 , the first end 11 of the first handle 1 is a grip portion, which is used by a doctor during operation. The second end 12 of the first handle 1 can be rotatably connected to the first end 21 of the second handle 2 through the first pin 14 , and the second end 22 of the second handle 2 can be connected to the casing of the stapler through the second pin 24 The body 54 is rotatably connected. Further, a first torsion spring 15 is also provided between the first handle 1 and the second handle 2, the first torsion spring 15 is sleeved on the first pin 14, and between the second handle 2 and the housing 54 of the stapler A second torsion spring 25 is also provided, and the second torsion spring 25 is sleeved on the second pin shaft 24 . Therefore, when the slider 3 is located in the first section of the chute 17, the instrument is in a safe state, and the first handle 1 can be rotated around the first pin 14 when the operator receives a small gripping force, and can be rotated under external force. When released, the first torsion spring 15 returns to the initial position in the clockwise direction, and the second handle 2 does not rotate at this time. When the slider 3 is located in the second section of the chute 17, the rotation of the first handle 1 will drive the rotation of the second handle 2, so that the second handle 2 rotates around the second pin shaft 24, and when the external force is released, the second handle 2 rotates through the second handle 2. The torsion spring 25 returns to its original state in the clockwise direction.
进一步地，该把手组件中还设置有滑块复位弹簧，滑块3对滑块复位弹簧施加作用力使滑块复位弹簧处于变形状态，滑块复位弹簧从变形状态恢复至初始状态时，推动滑块3从滑槽的第二段向滑槽17的第一段的方向移动。如图4所示，该滑块复位弹簧可选为滑块复位扭簧16，滑块复位扭簧16的第一端和第二端分别抵触滑块3和第二把手2。因此，在滑块3从滑槽17的第一段向第二段移动时，滑块3推动滑块复位扭簧16的第一端使该扭簧变形，在滑块3上解除外力时，滑块3会在滑块复位扭簧16的恢复力作用下返回至滑槽17的第一段。进一步地，滑块复位弹簧也可以是拉簧、压簧等等。Further, the handle assembly is also provided with a slider return spring, the slider 3 exerts a force on the slider return spring to make the slider return spring in a deformed state, and when the slider return spring returns from the deformed state to the initial state, pushes the slider. The block 3 moves from the second section of the chute in the direction of the first section of the chute 17 . As shown in FIG. 4 , the slider return spring can be selected as a slider return torsion spring 16 , and the first end and the second end of the slider return torsion spring 16 abut against the slider 3 and the second handle 2 respectively. Therefore, when the slider 3 moves from the first section of the chute 17 to the second section, the slider 3 pushes the first end of the slider reset torsion spring 16 to deform the torsion spring. When the external force is released on the slider 3, The slider 3 will return to the first section of the chute 17 under the action of the restoring force of the slider return torsion spring 16 . Further, the slider return spring can also be a tension spring, a compression spring, or the like.
下面结合图5～图9具体介绍本实施例中滑块的结构。滑块可以包括滑动部31和滑块导向部32，滑动部31可在滑槽17的内部移动，第二把手2设置有把手导向部26。滑块3位于滑槽17的第二段，且第一把手1被握持旋转时，滑块导向部32与把手导向部26抵触。The structure of the slider in this embodiment will be described in detail below with reference to FIGS. 5 to 9 . The sliding block may include a sliding part 31 and a sliding block guide part 32 , the sliding part 31 can move inside the sliding groove 17 , and the second handle 2 is provided with a handle guide part 26 . The slider 3 is located in the second section of the chute 17 , and when the first handle 1 is held and rotated, the slider guide 32 is in conflict with the handle guide 26 .
在该实施例中，第一把手1可以包括具有两侧侧壁的第一腔体13，第一腔体13的两侧侧壁上分别设置有一滑槽17，与此对应的，滑块3包括两个滑动部31，两个滑动部31分别嵌设于两个滑槽17中，且滑动部31分别可在对应的滑槽17中移动。In this embodiment, the first handle 1 may include a first cavity 13 having side walls on both sides, and a sliding groove 17 is respectively provided on the side walls of the first cavity 13 . Correspondingly, the slider 3 includes The two sliding parts 31 are respectively embedded in the two sliding grooves 17 , and the sliding parts 31 can move in the corresponding sliding grooves 17 respectively.
滑块部31分别位于所对应的滑槽17的第一段，且第一把手1逆时针被握持旋转时，第二把手2至少部分进入第一腔体13；由此，第一把手1的运动并不能带动第二把手2的运动。滑动部31分别位于所对应的滑槽17的第二段，且第一把手1逆时针被握持旋转时，滑块导向部32与把手导向部26抵触。由此，第一把手1的运动会带动第二把手2的运动，使第二把手在作用力下完成击发动作。The slider parts 31 are respectively located at the first section of the corresponding chute 17, and when the first handle 1 is held and rotated counterclockwise, the second handle 2 at least partially enters the first cavity 13; thus, the movement of the first handle 1 It cannot drive the movement of the second handle 2 . The sliding parts 31 are respectively located in the second section of the corresponding sliding grooves 17 , and when the first handle 1 is held and rotated counterclockwise, the sliding guide part 32 is in conflict with the handle guide part 26 . Therefore, the movement of the first handle 1 will drive the movement of the second handle 2, so that the second handle completes the firing action under the force.
进一步地，第二把手2可以包括具有两侧侧壁的第二腔体23，把手导向部26位于第二腔体23内，且把手导向部26的宽度小于或等于滑块导向部32的宽度。此处把手导向部26的宽度，指的是其在垂直于第一腔体13侧壁的方向的长度，滑块导向部32的宽度指的是其滑块导向部32在垂直于第一腔体13侧壁的方向的长度，但不限于此。Further, the second handle 2 may include a second cavity 23 with side walls on both sides, the handle guide portion 26 is located in the second cavity 23 , and the width of the handle guide portion 26 is smaller than or equal to the width of the slider guide portion 32 . Here, the width of the handle guide portion 26 refers to its length in the direction perpendicular to the side wall of the first cavity 13 , and the width of the slider guide portion 32 refers to the length of the slider guide portion 32 perpendicular to the first cavity. The length in the direction of the side wall of the body 13 is not limited to this.
进一步地，滑块3还可以包括一个凸台33，凸台33位于一滑动部31与滑块导向部32之间，凸台33的顶端设置有一凹部331，凹部331的内表面与第一把手1之间设置有上述滑块复位扭簧16。Further, the slider 3 may further include a boss 33, the boss 33 is located between a sliding part 31 and the slider guide part 32, a concave part 331 is provided at the top of the boss 33, and the inner surface of the concave part 331 is connected to the first handle 1 The above-mentioned slider return torsion spring 16 is arranged therebetween.
如图9所示，把手导向部26包括相互邻接的第一把手导向面261和第二把手导向面262，滑块导向部32包括引导段，即图中左边具有斜面的部分，引导段包括相互邻接的第一滑块导向面321和第二滑块导向面322，滑块导向部32在指针的作用下与把手导向部26抵触时，第二滑块导向面322与第二把手导向面262位置相对应且相互平行。此处位置相对应指的是，当滑块3位于滑槽17的第二段，且第一把手1逆时针旋转时，第二滑块导向面322与第二把手导向面262在沿滑槽17移动的方向上投影有重合，即第二滑块导向面322与第二把手导向面262抵触，第二滑块导向面322对第二把手导向面262施加作用力，在相互作用力的作用下，使滑块3有进一步向滑槽17第二段运动的趋势，从而获得比较滑块3与第二把手2之间更可靠的啮合，进而推动第二把手移动。As shown in FIG. 9 , the handle guide portion 26 includes a first handle guide surface 261 and a second handle guide surface 262 that are adjacent to each other, and the slider guide portion 32 includes a guide section, that is, the part with an inclined surface on the left side in the figure, and the guide section includes adjacent to each other. The first slider guide surface 321 and the second slider guide surface 322 are in the position of the second slider guide surface 322 and the second handle guide surface 262 when the slider guide portion 32 collides with the handle guide portion 26 under the action of the pointer. corresponding and parallel to each other. The corresponding position here means that when the slider 3 is located in the second section of the chute 17 and the first handle 1 rotates counterclockwise, the second slider guide surface 322 and the second handle guide surface 262 are along the chute 17 . The projections in the moving direction overlap, that is, the second slider guide surface 322 collides with the second handle guide surface 262, and the second slider guide surface 322 exerts a force on the second handle guide surface 262, under the action of the interaction force , so that the slider 3 has a tendency to move further toward the second section of the chute 17, so as to obtain a more reliable engagement between the slider 3 and the second handle 2, and then push the second handle to move.
可选地，为了避免模糊地带，即可能出现滑块导向部32和把手导向部26似啮合但是非啮合的状态，该实施例中进一步增加了相对的斜面导向机制。第二把手导向面262与滑槽17的长度方向之间具有一小于90°的夹角。即第二把手导向面262如图中所示是一个斜面。当第二把手导向面262与第二滑块导向面322抵触时，可以引导第二把手导向面262与第二滑块导向面322之间发生相对运动，增大两者的接触面积，并且当两者完全贴合时，比两个平面接触的面积更大，使得满足条件时，第一把手的运动对第二把手的推动更加稳定可靠。Optionally, in order to avoid an ambiguous area, that is, a state in which the slider guide portion 32 and the handle guide portion 26 seem to be engaged but not engaged, a relative inclined surface guide mechanism is further added in this embodiment. There is an included angle between the second handle guide surface 262 and the longitudinal direction of the chute 17 less than 90°. That is, the second handle guide surface 262 is an inclined surface as shown in the figure. When the second handle guide surface 262 collides with the second slider guide surface 322, relative movement between the second handle guide surface 262 and the second slider guide surface 322 can be guided to increase the contact area between the two, and when When the two are fully fitted, the contact area is larger than that of the two planes, so that when the conditions are met, the movement of the first handle pushes the second handle more stably and reliably.
进一步地，第二把手导向面262和第二滑块导向面322之间的摩擦力不至于妨碍第二把手导向面262与第二滑块导向面322之间的滑动。即第二滑块导向面322与第二把手导向面262相抵触，且第一把手1逆时针旋转时，第二滑块导向面322向第二把手导向面262施加推力F，推力F包括相互垂直的分量F1和分量F2，分量F1垂直于第二滑块导向面，且F1×β<F2，其中β为第二滑块导向面322和第二把手导向面262之间的摩擦系数。Further, the frictional force between the second handle guide surface 262 and the second slider guide surface 322 will not hinder the sliding between the second handle guide surface 262 and the second slider guide surface 322 . That is, when the second slider guide surface 322 is in conflict with the second handle guide surface 262, and the first handle 1 rotates counterclockwise, the second slider guide surface 322 exerts a thrust F on the second handle guide surface 262, and the thrust force F includes a mutually perpendicular The component F1 and the component F2 of the component F1 are perpendicular to the second slider guide surface, and F1×β<F2, where β is the friction coefficient between the second slider guide surface 322 and the second handle guide surface 262 .
采用该实施例中滑块导向部32和把手导向部26的结构时，因为两者是尖点对尖点，而点对点碰死的概率很小，可以忽略不计，因此接触后只会存在两种状态，要么完全啮合，要么完全脱离。When the structure of the slider guide part 32 and the handle guide part 26 in this embodiment is adopted, because the two are cusp to cusp, and the probability of point-to-point collision is very small and can be ignored, there are only two types of contact after contact. state, either fully engaged or fully disengaged.
进一步可选地，滑块导向部32还包括与引导段邻接的连接段，连接段即图中右侧的类似平台部分，但实际应用中也可以不为平台形状。平台部分的作用是加强引导段的强度及连接两侧的滑动部31。连接段包括第三滑块导向面323，其与所述第二滑块导向面322邻接.Further optionally, the slider guide portion 32 further includes a connecting segment adjacent to the guide segment, and the connecting segment is a similar platform portion on the right side in the figure, but may not be a platform shape in practical application. The function of the platform part is to strengthen the strength of the guide section and to connect the sliding parts 31 on both sides. The connecting section includes a third slider guide surface 323, which is adjacent to the second slider guide surface 322.
该实施例中滑块导向部32和把手导向部26的结构以及倾角等仅为一种具体的可选实施方式，在实际应用中，采用其他结构也是可以的，例如将第二滑块导向面322和第二把手导向面262均设置成平行于滑槽的延伸方向等等，均属于本发明的保护范围之内。In this embodiment, the structure and inclination of the slider guide portion 32 and the handle guide portion 26 are only a specific optional implementation. In practical applications, other structures are also possible, such as the second slider guide surface Both the 322 and the second handle guide surface 262 are arranged to be parallel to the extending direction of the chute, etc., which all fall within the protection scope of the present invention.
下面结合图9～图11来说明在滑块3位于滑槽17的第一段时，第一把手运动的过程。其中，图9～11中，第一把手1未旋转；图11中，第一把手1被握持而旋转。The following describes the process of the movement of the first handle when the slider 3 is located in the first section of the chute 17 with reference to FIGS. 9 to 11 . 9 to 11, the first handle 1 is not rotated; in FIG. 11, the first handle 1 is gripped and rotated.
如图10所述，指针4通过固定端可旋转固定至吻合器的壳体内部，指针4的第二端42在第一位置区域和第二位置区域之间移动时，指针4的第一端41也可随之移动。要说明的是，初始位置时滑块3在滑块扭簧16的作用下位于滑槽第一段的远离第二段的尽头即图示的右端位置。当然也可以是由指针4的第一端41来对滑块3的初始位置进行限位。图10中可以看出，随着旋钮的旋转，拉片对指针的第二端有拉力，当指针4的第二端42在拉片的作用下位于第一位置区域时，指针4的第一端逐渐拨动滑块3在滑槽17的第一段向第二段的方向移动，但未进入滑槽的第二段；滑块3位于滑槽17的第一段，即图中滑槽17的右端，此时第一把手1未旋转。图11中为第一把手1旋转后的状态。但是此时把手导向部26和滑块导向部32之间是不抵触的，即滑块3没有使第一把手1与第二把手2联动，第二把手2会部分进入第一腔体13中，而第二把手2本身的位置并没有发生变化，即使用者作用在第一把手1上的握持力并没有驱动第二把手的转动，因此第二把手2仍然是处于初始的保险位置中，不会对吻合器进行击发。由于第一扭簧15的扭力较击发力要小的多，此时的压力仅为克服第一扭簧15的力，医生虽然仍然可以按动第一把手1，却不会带动第二把手2，也就不会引起吻合器的击发，同时医生此时也能够得到触觉反馈，知道当前指针4未达到可击发区域，没有击发。As shown in FIG. 10 , the pointer 4 is rotatably fixed to the inside of the housing of the stapler through the fixed end, and when the second end 42 of the pointer 4 moves between the first position area and the second position area, the first end of the pointer 4 41 can also be moved with it. It should be noted that, in the initial position, the slider 3 is located at the end of the first section of the chute away from the second section under the action of the slider torsion spring 16, that is, the right end position as shown in the figure. Of course, the initial position of the slider 3 can also be limited by the first end 41 of the pointer 4 . It can be seen in FIG. 10 that with the rotation of the knob, the pull-tab exerts a pulling force on the second end of the pointer. When the second end 42 of the pointer 4 is located in the first position area under the action of the pull-tab, the first The slider 3 moves from the first section of the chute 17 to the second section, but does not enter the second section of the chute; the slider 3 is located in the first section of the chute 17, that is, the chute in the figure The right end of 17, the first handle 1 is not rotated at this time. In FIG. 11, the state after the rotation of the first handle 1 is shown. However, at this time, there is no conflict between the handle guide portion 26 and the slider guide portion 32, that is, the slider 3 does not cause the first handle 1 to be linked with the second handle 2, and the second handle 2 will partially enter the first cavity 13, The position of the second handle 2 itself has not changed, that is, the user's grip force on the first handle 1 does not drive the rotation of the second handle, so the second handle 2 is still in the initial safety position, not The stapler will fire. Since the torsion force of the first torsion spring 15 is much smaller than the firing force, the pressure at this time is only to overcome the force of the first torsion spring 15. Although the doctor can still press the first handle 1, it will not drive the second handle 2. , it will not cause the firing of the stapler, and the doctor can also get tactile feedback at this time, knowing that the current pointer 4 has not reached the firing area and is not firing.
下面结合图12～图21来进一步介绍一下滑块3位于滑槽17的第二段时，第一把手运动的过程。其中，图12～13为该实施例的滑块3位于滑槽17的第二段的两种位置的示意图。12 to 21, the process of the movement of the first handle when the slider 3 is located in the second section of the chute 17 will be further described below. 12 to 13 are schematic diagrams of two positions of the slider 3 in the second section of the chute 17 in this embodiment.
即在该实施例中，滑块3位于滑槽17的第二段(即图中滑槽17的左端)有两种情况：第一种，滑块3位于滑槽17的第二段的较近位置，即图13中偏右边的滑块，滑动部31距离滑槽17的第二端的端面还有一定的距离；第二种，滑块3位于滑槽17的第二段的较远位置，即图13中偏左边的滑块，滑动部基本上贴紧滑槽17的第二端的端面。在该实施例中，这两种情况均可以实现第一把手1和第二把手2的联动，并且，在第一种情况和第二种情况之间的状态，也可以实现第一把手1和第二把手2的联动，这样增加了医生操作时可击发的区域，并且在击发过程中更加稳定，也一定程度降低了医生操作的难度。但是此处仅为一种实施方式，在实际应用中，将滑槽17的左侧端面向右侧缩进，使得只存在第一种情况也是可以的，均属于本发明的保护范围之内。That is, in this embodiment, the slider 3 is located in the second segment of the chute 17 (ie, the left end of the chute 17 in the figure) in two cases: the first is that the slider 3 is located in the second segment of the chute 17. In the near position, that is, the slider on the right side in FIG. 13 , the sliding part 31 is still a certain distance from the end face of the second end of the chute 17 ; second, the slider 3 is located at a farther position of the second section of the chute 17 . , that is, the slider on the left side in FIG. 13 , the sliding portion basically abuts against the end face of the second end of the chute 17 . In this embodiment, the linkage between the first handle 1 and the second handle 2 can be realized in both cases, and in the state between the first and second situations, the first handle 1 and the second handle can also be realized. The linkage of the handle 2 increases the area that can be fired when the doctor operates, and is more stable during the firing process, which also reduces the difficulty of the doctor's operation to a certain extent. However, this is only an embodiment. In practical application, it is possible to indent the left end of the chute 17 to the right, so that only the first situation exists, which falls within the protection scope of the present invention.
如图14所示，指针4在拉片的作用下转动，指针4的第二端42进入刚刚第二位置区域L，滑块3位于滑槽17的第二段的较近位置，且第一把手1未旋转。此时若继续旋转旋钮，拉片是会继续驱动指针4的第一端41推动滑块3沿着滑槽17向左侧移动，对应地钉砧和钉仓之间的距离也随之逐渐减小。随之，如图15所示，滑块导向部32和把手导向部26在沿滑槽17的运动方向上的投影重合部分逐渐增大，这样会获得第一把手1与第二把手2之间更可靠的连接。如图16所示，第一把手1和第二把手2之间由于滑块3的作用形成了联动关系，当握持第一把手1时，第一把手1的旋转也带动了第二把手2从保险位置旋转至击发位置，第二把手2的第二端会与吻合器的击发块55相接触，从而对吻合器完成击发。击发过程中第一把手1的第二端在旋转过程中抵持拉片，使拉片凸抬，与指针4脱开，指针4在指针复位机构的作用下得以复位。As shown in FIG. 14 , the pointer 4 is rotated under the action of the pull tab, the second end 42 of the pointer 4 enters the second position area L, the slider 3 is located at a position closer to the second section of the chute 17, and the first handle 1 is not rotated. At this time, if you continue to rotate the knob, the pull tab will continue to drive the first end 41 of the pointer 4 to push the slider 3 to move to the left along the chute 17, and the distance between the nail anvil and the nail cartridge will gradually decrease accordingly. Small. Subsequently, as shown in FIG. 15 , the overlapping portion of the projection of the slider guide portion 32 and the handle guide portion 26 along the moving direction of the chute 17 is gradually increased, so that a greater distance between the first handle 1 and the second handle 2 will be obtained. Reliable connection. As shown in Fig. 16, a linkage relationship is formed between the first handle 1 and the second handle 2 due to the action of the slider 3. When the first handle 1 is held, the rotation of the first handle 1 also drives the second handle 2 from the safe position When rotated to the firing position, the second end of the second handle 2 will come into contact with the firing block 55 of the stapler, thereby completing the firing of the stapler. During the firing process, the second end of the first handle 1 resists the pull tab during the rotation process, so that the pull tab is raised and disengaged from the pointer 4, and the pointer 4 is reset under the action of the pointer reset mechanism.
击发完成后，第一把手1未复位而指针4复位时，即使用者还保持握持状态时，把手组件的结构如图17所示。此时指针4的第二端42复位至第一位置区域。而由于把手导向部26对滑块导向部32的限制作用，滑块3仍没有复位。此时如果松开第一把手1，第一把手1旋转回原位后，滑块3即可以在滑块复位扭簧16的作用下返回至滑槽17的第一段，第二把手也在第二扭簧25的恢复力下顺时针旋转返回至保险位置。After the firing is completed, when the first handle 1 is not reset but the pointer 4 is reset, that is, when the user is still holding the state, the structure of the handle assembly is shown in FIG. 17 . The second end 42 of the pointer 4 is now reset to the first position area. However, due to the restricting effect of the handle guide portion 26 on the slider guide portion 32 , the slider 3 has not been reset. At this time, if the first handle 1 is released, after the first handle 1 is rotated back to its original position, the slider 3 can return to the first section of the chute 17 under the action of the slider reset torsion spring 16, and the second handle is also in the second The torsion spring 25 rotates clockwise to return to the safe position under the restoring force of the torsion spring 25 .
如图18所示，滑块位于滑槽17的第二段的较远位置，且第一把手1未旋转时。指针4的第二端42进入第二位置区域L，且相比于图14中指针4的第二端42的位置更偏向右侧，而指针4的第一端41也就更偏向于左侧，也就推动滑块3更加贴近滑槽17的第二端端面。如图19所示，滑块导向部32和把手导向部26在沿滑槽17的运动方向上投影具有更多的重合部分，第一把手1与第二把手2具有更可靠的连接。As shown in FIG. 18 , the slider is located at a far position of the second section of the chute 17 and the first handle 1 is not rotated. The second end 42 of the pointer 4 enters the second position area L, and is more inclined to the right than the second end 42 of the pointer 4 in FIG. 14 , and the first end 41 of the pointer 4 is more inclined to the left , which also pushes the slider 3 to be closer to the second end face of the chute 17 . As shown in FIG. 19 , the slider guide portion 32 and the handle guide portion 26 have more overlapping parts in the projection along the moving direction of the chute 17 , and the first handle 1 and the second handle 2 have a more reliable connection.
如图20所示，随着第一把手1的旋转，第一把手1和第二把手2之间由于滑块3形成的联动关系使第一把手1的旋转也带动了第二把手2从保险位置旋转至击发位置，第二把手2的第二端会与吻合器的击发块55相接触，从而对吻合器完成击发。As shown in FIG. 20, with the rotation of the first handle 1, the rotation of the first handle 1 also drives the second handle 2 to rotate from the safe position to the In the firing position, the second end of the second handle 2 will be in contact with the firing block 55 of the stapler, thereby completing the firing of the stapler.
击发完成后，第一把手1未复位而指针4复位时，把手组件的结构如图21所示。过程同指针4刚刚进入绿色区域时的状态相同，这里不再重复。After the firing is completed, when the first handle 1 is not reset but the pointer 4 is reset, the structure of the handle assembly is shown in FIG. 21 . The process is the same as the state when the pointer 4 has just entered the green area, and will not be repeated here.
本发明实施例还提供一种吻合器，包括把手组件。在吻合器未达到可击发状态时，第一把手不会驱动第二把手，也就不会击发吻合器，医生也可以通过操作体验来判断击发状态，只有吻合器达到可击发状态时，第一把手的运动才会带动第二把手的运动，进而击发吻合器。从而在避免吻合器被误击发的基础上，同时避免发生吻合器机壳开裂的情况。An embodiment of the present invention also provides a stapler, which includes a handle assembly. When the stapler does not reach the firing state, the first handle will not drive the second handle, and the stapler will not be fired. The doctor can also judge the firing state through the operation experience. Only when the stapler reaches the firing state, the first handle will not be activated. The movement will drive the movement of the second handle, thereby firing the stapler. Therefore, on the basis of preventing the stapler from being fired by mistake, the situation of cracking of the stapler housing can be avoided at the same time.
本发明所提供的把手组件及包括其的吻合器具有下列优点：The handle assembly and the stapler including the handle assembly provided by the present invention have the following advantages:
本发明将把手组件分为第一把手和第二把手，只有第二把手的运动才能够击发吻合器执行切割和缝合动作；在使用过程中，无论吻合器是否达到可击发位置，医生均可以按动第一把手，然而，在吻合器未达到可击发位置时，第一把手不会驱动第二把手，也就不会击发吻合器，医生也可以通过操作体验来判断击发状态，只有吻合器达到可击发位置时，第一把手的运动才会带动第二把手的运动，进而击发吻合器，从而可以避免用力按动把手可能导致的吻合器损坏，并且提高了医生的使用体验。The present invention divides the handle assembly into a first handle and a second handle, and only the movement of the second handle can trigger the stapler to perform cutting and suturing; during use, no matter whether the stapler reaches the triggerable position, the doctor can press The first handle, however, when the stapler does not reach the firing position, the first handle will not drive the second handle, and the stapler will not be fired. The doctor can also judge the firing state through operating experience. Only when the stapler reaches the firing position Only when the movement of the first handle drives the movement of the second handle, and then the stapler is fired, the stapler can be prevented from being damaged by pressing the handle forcefully, and the use experience of the doctor is improved.
