一种腔镜吻合器A laparoscopic stapler

技术领域technical field

本实用新型涉及医疗器械领域，特别涉及一种腔镜吻合器。The utility model relates to the field of medical instruments, in particular to a laparoscopic stapler.

背景技术Background technique

目前，微创手术占据了外科手术中的重要地位。腔镜吻合器是微创手术中常用的手术器械。腔镜吻合器的工作原理是通过组件钳口夹持在病灶部位附近的特定位置，进行切除，切除的同时进行缝合。在一台手术中，需要根据组织的厚度、长度来选择不同型号的工作组件，难免忘记工作组件是否已经被使用过。如果工作组件中没有检测钉匣的机构，不能确认钉匣是否已经安装或者安装的钉匣已经被使用，在没有安装钉匣或者钉匣已经进行一次缝合的情况下，如果击发切割刀，则会只切割组织而无法缝合或者切割已经缝合好的组织，从而导致手术失败或者二次手术。At present, minimally invasive surgery occupies an important position in surgery. Laparoscopic stapler is a commonly used surgical instrument in minimally invasive surgery. The working principle of the laparoscopic stapler is to clamp it at a specific position near the lesion through the jaws of the components, perform resection, and suture at the same time. In an operation, it is necessary to select different types of working components according to the thickness and length of the tissue, and it is inevitable to forget whether the working components have been used. If there is no mechanism for detecting the nail box in the working assembly, it cannot be confirmed whether the nail box has been installed or the installed nail box has been used. Only cutting tissue without suturing or cutting tissue that has been sutured, resulting in surgical failure or secondary surgery.

The working assembly includes anabutment seat 1, anail magazine assembly 2, anail magazine base 3 and acutting knife 5, and also includes a cutting knife limiting assembly. The assembly is used to limit the movement of the cutting knife to the distal end after the nail magazine assembly is not installed or the nail magazine assembly has been used once.Groove 302,boss 301, andelastic part 4 on the top, wherein theprotrusion 503 is set corresponding to thegroove 302, and theelastic part 4 exerts elastic force on theprotrusion 503. Under the action of theelastic part 4, theprotrusion 503 can snap into thegroove 302 and abut against the end surface of theboss 301 . Preferably, there are two protrusions, protrusions and grooves, the two protrusions are respectively arranged on both sides of the cutting knife, and the grooves and protrusions are respectively arranged corresponding to the protrusions. The shapes of the protrusion and the groove are not specifically limited, as long as the protrusion can be snapped into the groove.

参见附图6-7，切割刀5还包括上刀架501和下刀架502，下刀架502穿过钉匣底座3上的矩形孔，使切割刀进入钉匣底座3上的长条轨道。切割刀向远端运动，刀架501可以进入抵钉座1的轨道101a，从而切割刀可以沿着钉匣底座3上的长条轨道和抵钉座上的轨道101a向远端运动实现对组织的切割。Referring to accompanying drawings 6-7, thecutting knife 5 also includes anupper knife rest 501 and alower knife rest 502, and thelower knife rest 502 passes through the rectangular hole on thenail box base 3, so that the cutting knife enters the long track on thenail box base 3 . The cutting knife moves to the distal end, and theknife holder 501 can enter thetrack 101a of thenail abutment 1, so that the cutting knife can move to the distal end along the long track on thenail box base 3 and thetrack 101a on the nail anvil to achieve tissue cutting.

工作组件还包括推钉滑块201，参见附图8，推钉滑块201具有支撑面201a,切割刀的前端搭在支撑面201a上，支撑面距离推钉滑块201的底面具有一定的高度，从而将切割刀前端抬起，当击发力推动切割刀5向远端运动时，凸起部503可以克服弹性部4的弹力，使上刀架501进入抵钉座1的轨道101a，从而可以推动推钉滑块201向组件远端移动，进行缝合切割操作。The working assembly also includes apush nail slider 201. Referring to accompanying drawing 8, the pushnail slide block 201 has asupport surface 201a, the front end of the cutting knife rides on thesupport surface 201a, and the support surface has a certain height from the bottom surface of the pushnail slide block 201 , so that the front end of the cutting knife is lifted, and when the percussion force pushes thecutting knife 5 to move to the distal end, the raisedpart 503 can overcome the elastic force of theelastic part 4, so that theupper knife rest 501 enters thetrack 101a of theabutting seat 1, thereby Thenail pusher slider 201 can be pushed to move toward the distal end of the assembly to perform suturing and cutting operations.

优选地，参见附图4-5，弹性部件为弹片，弹片包括平整段和折弯段，平整段固定在钉匣底座3上，折弯段设有开口部，切割刀5的至少一部分设置于开口部内，折弯部能够对凸起部503施加弹力，使得凸起部可以卡入凹槽内，抵住凸台301的端面，从而阻止切割刀向远端运动。Preferably, referring to accompanying drawings 4-5, the elastic member is a shrapnel, and the shrapnel includes a flat section and a bent section, the flat section is fixed on thebase 3 of the nail box, the bent section is provided with an opening, and at least a part of thecutting knife 5 is arranged on In the opening, the bent portion can apply elastic force to the raisedportion 503, so that the raised portion can snap into the groove and abut against the end surface of theboss 301, thereby preventing the cutting knife from moving toward the distal end.

在装配工作组件时，首先将保险弹片4的平整段固定在钉匣底座3上，下刀架502穿过钉匣底座3上的矩形孔，使切割刀5进入钉匣底座3上的长条轨道。将抵钉座1与钉匣组件2装配上，完成工作组件装配。When assembling the working components, first fix the flat section of thesafety spring 4 on thenail box base 3, and thelower knife rest 502 passes through the rectangular hole on thenail box base 3, so that thecutting knife 5 enters the strip on thenail box base 3 track. Assemble thenail anvil 1 and thenail magazine assembly 2 to complete the assembly of the working components.

参见附图9-12，钉匣组件2正常情况：钉匣组件正确安装并且没有使用过，由于切割刀5的前端搭在推钉滑块201的面201a上，击发力使切割刀5向远端运动时，推钉滑块的支撑作用使切割刀上的凸起503可以克服弹片的弹力顶起弹片的折弯段，从而使上刀架501可以顺利进入抵钉座1的轨道101a继续向远端运动，接着推动推钉滑块201向组件远端移动，可以正常进行缝合切割操作。Referring to accompanying drawings 9-12, the normal condition of the nail magazine assembly 2: the nail magazine assembly is installed correctly and has not been used. Since the front end of thecutting knife 5 rides on thesurface 201a of thepush nail slider 201, the firing force makes thecutting knife 5 to When the distal end moves, the supporting function of the push nail slider makes theprotrusion 503 on the cutting knife overcome the elastic force of the shrapnel and lift up the bending section of the shrapnel, so that theupper knife rest 501 can smoothly enter thetrack 101a of thenail holder 1 to continue Move to the distal end, and then push thenail pushing slider 201 to move to the distal end of the assembly, and the suturing and cutting operation can be performed normally.

钉匣组件2异常情况：当钉匣组件未安装或者已经使用过，此时推钉滑块201不在初始位置，此时，切割刀5失去推钉滑块201的支撑，当击发时，切割刀上的凸起503受到弹片的折弯段向下的弹力，使凸起503进入刀钉匣底座3的凹槽302内，顶住凸台301的端面，从而无法向远端移动，上刀架501也无法进入抵钉座1的轨道101a，此时医务工作人员可发现组件异常，更换新组件，避免医疗事故发生。Abnormal situation of nail magazine assembly 2: when the nail magazine assembly has not been installed or has been used, thepush nail slider 201 is not in the initial position. At this time, thecutter 5 loses the support of thenail push slider 201. Theprotrusion 503 on the top is subjected to the downward elastic force of the bending section of the shrapnel, so that theprotrusion 503 enters thegroove 302 of theknife magazine base 3, and withstands the end surface of theboss 301, so that it cannot move to the far end. 501 also cannot enter thetrack 101a of thenail abutment 1, at this time, the medical staff can find that the components are abnormal and replace them with new components, so as to avoid medical accidents.

本实用新型的目的是为了避免钉匣组件异常时，切割刀仍然可以向远端运动进行切割动作，对手术造成风险。如果没有本实用新型的结构，由于同一台手术需要多种型号的组件，容易将使用过的组件二次使用，这时候，吻合器无缝合效果而只有切割效果，会对组织进行切割、误伤，大大增加了手术风险。本实用新型的吻合器可降低上述手术风险。The purpose of the utility model is to avoid that when the nail box assembly is abnormal, the cutting knife can still move to the far end for cutting action, which will cause risks to the operation. If there is no structure of the present utility model, since the same operation requires multiple types of components, it is easy to use the used components twice. At this time, the stapler has no suture effect but only a cutting effect, which will cut and accidentally injure the tissue. Greatly increased surgical risk. The stapler of the utility model can reduce the above operation risk.
