技术领域technical field

本发明涉及一种圆管型装订仪的手术附件，尤其涉及一种圆管型装订仪的引导附件。The invention relates to an operation accessory of a circular tube binding instrument, in particular to a guiding accessory of a circular tube binding instrument.

背景技术Background technique

圆管型装订仪是一种广泛用于圆管型组织缝切手术的外科器械，由圆形的钉头组件与击发组件组成；将两段需要连接起来的圆管型组织放置在钉头组件的钉砧与钉仓之间，调整钉砧与钉仓的距离来逐渐夹紧组织，然后操作击发组件使钉成形，完成两段组织的连接。The circular tubular stapler is a surgical instrument widely used in circular tubular tissue suturing operations. It is composed of a circular nail head assembly and a firing assembly; two sections of circular tubular tissue that need to be connected are placed in the nail head assembly Between the staple anvil and the staple cartridge, adjust the distance between the staple anvil and the staple cartridge to gradually clamp the tissue, and then operate the firing assembly to shape the nail and complete the connection of the two sections of tissue.

在实际的手术操作中，有两种手术的圆管型装订仪进入管道比较困难，分别是低位直肠手术与胃旁路手术。第一种低位直肠手术，采用的是直径为33毫米的圆管型装订仪，需经肛门进行手术，由于肛门为一个肌性开口，正常状况其直径较小，将33毫米的器械插入到肛门比较困难。第二种胃旁路手术，采用的是直径为25毫米的圆管型装订仪，需进入小肠进行手术，小肠为人体的消化管道，内壁有很多粘膜，而圆管型装订仪由于端面较大，且由于结构原因表面不够圆滑，在小肠内穿行易对粘膜造成损伤。In the actual operation, there are two types of operations where it is difficult for the circular tube-type stapler to enter the pipeline, namely, low rectal surgery and gastric bypass surgery. The first type of low rectal surgery uses a circular tube binding instrument with a diameter of 33 mm. The operation needs to be performed through the anus. Since the anus is a muscular opening, its diameter is normally small, and a 33 mm instrument is inserted into the anus. more difficult. The second type of gastric bypass surgery uses a circular tube binding instrument with a diameter of 25 mm, which needs to enter the small intestine for surgery. The small intestine is the digestive tract of the human body, and there are many mucous membranes on the inner wall. , and due to structural reasons, the surface is not smooth enough, and it is easy to cause damage to the mucosa when passing through the small intestine.

目前解决上述问题的现有技术为美国专利申请US2009020410揭示的一种套设在圆管型装订仪钉仓组件外周的辅助器械，可以引导圆管形装订仪的钉仓组件进入人体并穿过肠道，而且在其到达手术预定位置之后可以把这个辅助器械从钉仓组件上卸掉，不影响圆管型装订仪的后续操作。该辅助器械可帮助医生将钉仓组件顺利地放入到预定的位置，但是目前此辅助器械比较昂贵，还不能被广泛地提供给中国市场。At present, the existing technology to solve the above problems is an auxiliary device sleeved on the outer periphery of the staple cartridge assembly of the circular tubular stapler disclosed in US patent application US2009020410, which can guide the staple cartridge assembly of the circular tubular stapler into the human body and pass through the intestines. Road, and this auxiliary instrument can be removed from the staple cartridge assembly after it reaches the predetermined position of the operation, without affecting the subsequent operation of the circular tube-type stapler. This auxiliary device can help the doctor to put the staple cartridge assembly into the predetermined position smoothly, but at present this auxiliary device is relatively expensive and cannot be widely provided to the Chinese market.

具体实施方式Detailed ways

本发明揭示了一种圆管型装订仪的辅助器械，尤其是一种用于引导圆管型装订仪进入体内的引导附件。The invention discloses an auxiliary device for a circular tube binding instrument, in particular a guiding accessory for guiding the circular tube binding instrument into the body.

现有技术的圆管型装订仪包括钉砧组件、钉仓组件、固定于所述钉仓组件近端的圆管；所述钉仓组件包括相互固定的钉筒1和钉仓2，所述钉筒1的近端设有至少一个线孔3。The circular tube type binding instrument of the prior art comprises a nail anvil assembly, a nail bin assembly, a round tube fixed to the proximal end of the nail bin assembly; the nail bin assembly includes anail barrel 1 and anail bin 2 fixed to each other, and the The proximal end of thenail barrel 1 is provided with at least onewire hole 3 .

如图1至图4所示的第一实施例中，所述引导附件包括：用于套设于所述圆管型装订仪的远端的套设部4，设于所述套设部4远端的引导部6，以及设于所述套设部4近端的向外发散设置的用于握持的凸边5。In the first embodiment shown in FIGS. 1 to 4 , the guide accessory includes: asleeve part 4 for being sleeved on the far end of the round tube type binding instrument, and is arranged on thesleeve part 4 Theguide part 6 at the distal end, and the protrudingedge 5 for holding that is arranged on the proximal end of thesleeve part 4 and diverges outward.

所述套设部4为圆筒形，其内径大于所述钉筒的外径，这样整个引导附件可以很容易地套设在钉筒的外侧。Thesleeve part 4 is cylindrical, and its inner diameter is larger than the outer diameter of the nail barrel, so that the entire guide attachment can be easily sleeved on the outside of the nail barrel.

所述引导部6的外轮廓为一个圆锥形，所述圆锥形的内腔呈中空设置。所述引导部6的最大外径等于所述套设部的最小外径，所述引导部6为螺旋件，所述螺旋件的螺纹线61的一端与一牵引件7连接，另一端与所述套设部4连接。所述螺旋件的相邻的螺纹线61之间均垂直设有一组加强筋62，所述引导部6与套设部4之间的连接也是依靠该加强筋62。所述加强筋62为一端窄而小的塑胶件，类似于饮料瓶盖，很容易被扯断。当引导部6与套设部4之间的加强筋62被扯断后，所述引导部6与套设部4之间就失去连接，相互脱离。The outer contour of theguide part 6 is a cone, and the inner cavity of the cone is hollow. The maximum outer diameter of theguide part 6 is equal to the minimum outer diameter of the sleeve part, theguide part 6 is a screw, one end of thethread 61 of the screw is connected with atraction part 7, and the other end is connected with the Thesleeve part 4 is connected. A group of reinforcingribs 62 are vertically arranged betweenadjacent thread lines 61 of the spiral member, and the connection between the guidingpart 6 and thesleeve part 4 also depends on the reinforcingribs 62 . The reinforcingrib 62 is a narrow and small plastic part at one end, similar to a beverage bottle cap, which is easy to be torn off. When the reinforcingrib 62 between theguide part 6 and thesleeve part 4 is torn off, the connection between theguide part 6 and thesleeve part 4 is lost and separated from each other.

本例中，所述牵引件7的一端连接于螺纹线61的最远端中心。所述牵引件7从所述钉筒的线孔3穿过，所述牵引件7的另一端设有一拉环8。In this example, one end of the pullingmember 7 is connected to the center of the farthest end of the threadedline 61 . The pullingmember 7 passes through thethread hole 3 of the nail barrel, and apull ring 8 is provided at the other end of the pullingmember 7 .

第一实施例在操作时，先将引导附件套在钉仓组件的外侧，通过其圆锥形的结构引导圆管型装订仪进入人体内的手术位置；然后通过拉环拉扯牵引件，使连接于牵引件的螺旋线61受力并扯断加强筋62，这样整个引导部的螺旋线61呈条状一次性地从线孔3中被抽出于圆管型装订仪外。接着，手持凸边5将套在钉筒外的套设部4向圆管型装订仪的近端拉，使其退出于人体内。这样，圆管型装订仪即可进行手术。In the operation of the first embodiment, firstly, the guide attachment is placed on the outside of the staple cartridge assembly, and the circular tube-type binding instrument is guided into the operation position in the human body through its conical structure; Thehelical wire 61 of the traction member is stressed and the reinforcingrib 62 is torn off, so that thehelical wire 61 of the whole guide part is pulled out of the circular tube type binding instrument from thewire hole 3 at one time in a strip shape. Next, hold theflange 5 and pull thesheathing part 4 covered outside the nail barrel toward the proximal end of the round tube type binding instrument, so that it withdraws from the human body. In this way, the round tube type binding instrument can perform the operation.

图5、图6揭示了本发明的第二实施例，其套设部为半圆筒形。本例中最大的特点在于：所述螺旋件为两条间隔围绕的螺纹线61，类似于现有的蚊香。该两条螺纹线61的一端相互连接在一起，另一端均与所述套设部通过加强筋62连接。所述牵引件7钩在所述两条螺纹线的连接在一起的端部上。Fig. 5 and Fig. 6 disclose the second embodiment of the present invention, and the sheathing part is semi-cylindrical. The biggest feature in this example is that the spiral member is twohelical lines 61 surrounded by intervals, similar to the existing mosquito coils. One ends of the two threadedwires 61 are connected to each other, and the other ends are connected to the sleeve part through reinforcingribs 62 . Thepuller 7 is hooked on the connected ends of the two threads.

第二实施例在操作时，先将引导附件套在钉仓组件的外侧，通过其圆锥形的结构引导圆管型装订仪进入人体内的手术位置；然后拉扯牵引件，两条螺纹线的连接端受力并扯断加强筋62，这样整个引导部的螺旋线61呈条状一次性地从线孔3中被抽出于圆管型装订仪外。由于两条螺旋线61同时变形并拉出于圆管型装订仪外，所以其操作时间较第一实施例快。接着，手持凸边5将套在钉筒外的套设部4向圆管型装订仪的近端拉动退出于人体内。这样，圆管型装订仪即可进行手术。In the operation of the second embodiment, the guide attachment is first placed on the outside of the staple cartridge assembly, and the circular tube-type binding instrument is guided into the surgical position in the human body through its conical structure; then the traction member is pulled, and the connection of the two threads The end is stressed and the reinforcingrib 62 is torn off, so that thehelical wire 61 of the whole guide portion is pulled out of the round tube type binding instrument from thewire hole 3 at one time in a strip shape. Since the twohelical wires 61 are simultaneously deformed and pulled out of the round tube type binding instrument, the operation time is faster than that of the first embodiment. Next, hold theflange 5 and pull thesheathing part 4 covered outside the nail barrel toward the proximal end of the circular tube-type binding instrument and withdraw it from the human body. In this way, the round tube type binding instrument can perform the operation.

图7至图9揭示了本发明的第三实施例。该实施例的特点在于：所述引导部6为一整体注塑而成的柔性U型回旋件，所述U型回旋件的中心横截面为U型，所述引导部6包括一个近端17和一个远端15，所述远端15的外径小于到近端17的外径，所述近端17的外径等于钉仓3或钉筒1的外径。本例与前述实施例的最大区别在于引导部的“螺旋线”的环绕形状。7 to 9 disclose a third embodiment of the present invention. The feature of this embodiment is that: theguide part 6 is a flexible U-shaped swivel part formed by integral injection molding, the central cross-section of the U-shaped swivel part is U-shaped, and theguide part 6 includes aproximal end 17 and Adistal end 15, the outer diameter of thedistal end 15 is smaller than the outer diameter of theproximal end 17, and the outer diameter of theproximal end 17 is equal to the outer diameter of thestaple cartridge 3 or thenail barrel 1. The biggest difference between this example and the preceding embodiments lies in the surrounding shape of the "helix" of the guide.

因此表明，本发明的引导附件的“螺旋线”的形状不是重点，除了本发明揭示的螺旋状、U型回旋状，还可以是其他的形状，只要是一条完整的塑胶条围设的即可，即该第三实施例的U型回旋状塑胶件也可以用于第一实施例。Therefore, it is shown that the shape of the "helix" of the guide attachment of the present invention is not the key point, except for the spiral shape and U-shaped spiral shape disclosed by the present invention, it can also be other shapes, as long as it is surrounded by a complete plastic strip. , that is, the U-shaped convoluted plastic part of the third embodiment can also be used in the first embodiment.

本例中，所述引导部的近端17为一与钉仓面贴合的平面25，套设部4为套设于所述钉仓外周的薄壁，所述薄壁和引导部6为一整体注塑而成的柔性U型回旋件。所述薄壁上设有固接于钉仓上的卡箍39。In this example, theproximal end 17 of the guide part is aplane 25 that fits with the surface of the staple cartridge, thesleeve part 4 is a thin wall sleeved on the outer periphery of the staple cartridge, and the thin wall and theguide part 6 are A flexible U-shaped rotary part formed by integral injection molding. The thin wall is provided with ahoop 39 fixedly connected to the staple cartridge.

由于操作方法与第一实施例大致相同，因此在此不再赘述。Since the operation method is substantially the same as that of the first embodiment, it will not be repeated here.

图10和图11揭示了本发明的第四实施例。本实施例与第一实施例类似，所述引导部6为一整体环绕而形成的螺旋形柔性塑胶件，即该引导部6是由一个柔性塑胶件整体环绕围成的螺旋形物件，类似于弹簧。所述的引导部6即为一段“弹簧线”。10 and 11 disclose a fourth embodiment of the present invention. This embodiment is similar to the first embodiment, theguide part 6 is a spiral flexible plastic part formed around the whole, that is, theguide part 6 is a spiral object surrounded by a flexible plastic part as a whole, similar to spring. Theguide part 6 is a section of "spring wire".

本实施例中，所述引导部6的中空内腔的远端15的底部向内凸设有一个中心筒21，所述中心筒21的内径等于所述钉砧拉杆的远端外径。这样在初始状态时，所述引导附件可以通过中心筒21套设在钉砧拉杆上，使所述引导附件配接于所述圆管型装订仪上。In this embodiment, the bottom of thedistal end 15 of the hollow inner cavity of theguide part 6 is provided with acentral cylinder 21 protruding inward, and the inner diameter of thecentral cylinder 21 is equal to the outer diameter of the distal end of the anvil rod. In this way, in the initial state, the guide accessory can be sleeved on the anvil pull rod through thecentral cylinder 21, so that the guide accessory can be matched with the round tube type binding instrument.

所述中心筒21的近端壁上开设有一个牵引孔23，所述中心筒的近端为整个柔性塑胶件的一端，即为“弹簧线”的一端。Atraction hole 23 is opened on the proximal end wall of thecentral cylinder 21, and the proximal end of the central cylinder is one end of the whole flexible plastic part, that is, one end of the "spring wire".

所述引导部6的近端为一与钉仓面5贴合的平面25。套设部4为套设于所述钉仓外周的薄壁，所述薄壁和引导部6为一整体注塑而成的螺旋形柔性塑胶件。The proximal end of theguide part 6 is aplane 25 that fits with thecartridge surface 5 . Thesleeve part 4 is a thin wall sleeved on the outer periphery of the staple cartridge, and the thin wall and theguide part 6 are a spiral flexible plastic part formed by integral injection molding.

该实施例在操作时，先将引导附件套接在钉仓组件的远端，然后引导圆管型装订仪进入人体内，接着拉扯连接于牵引孔的牵引线，使所述引导附件整体呈条状一次性地被抽出于圆管型装订仪，类似于将“弹簧线”拉成一直线。When this embodiment is in operation, the guide attachment is firstly sleeved on the distal end of the staple cartridge assembly, then the circular tube-type binding instrument is guided into the human body, and then the pull wire connected to the pull hole is pulled, so that the guide attachment is in a striped shape as a whole. The shape is pulled out of the round tube binding instrument at one time, similar to pulling a "spring wire" into a straight line.

上述的实施例的引导部都可从装订仪内部将引导器抽出，即圆管型装订仪钉筒上设有至少1个引导孔，所述的呈带状体的引导部从所述引导孔中脱离所述圆管型装订仪。当然上述的实施例也可以从装订仪外侧抽出，只要改变牵引件位于引导器上的连接位置即可。The guide parts of the above-mentioned embodiments can be drawn out from the inside of the binding instrument, that is, the nail cylinder of the round tube type binding instrument is provided with at least one guide hole, and the guide part in the shape of a strip is drawn out from the guide hole.
