一种具有推钉指示功能的腔镜吻合器A laparoscopic stapler with push nail indication function

技术领域technical field

本实用新型涉及一种医疗器械，尤其涉及一种具有推钉指示功能的腔镜吻合器。The utility model relates to a medical instrument, in particular to an endoscopic stapler with the function of pushing nails.

背景技术Background technique

腔内吻合器通常可包括两个细长的钳口构件，这两个钳口构件分别用于抓取或夹紧组织。在某些手术用吻合器中，其中一个钳口构件具有装载了多个布置成至少两横排的吻合钉的吻合钉钉仓，而另一钳口构件具有砧座，在吻合钉从吻合钉钉仓被推出时，该砧座限定了用于形成吻合钉腿的表面,吻合操作是通过凸轮构件实现的，当凸轮构件纵向行进通过吻合钉钉仓时，对吻合钉推动器产生作用，从而顺序将吻合钉从吻合钉钉仓中射出。刀片可在吻合钉排之间行进，用来纵向切割和/或打开吻合钉排间被吻合起来的组织。现有技术中，申请号为202010732474.0公开了一种用于吻合器的驱动切换机构及吻合器，具体为一种用于腔镜手术的吻合器，配合差动控制件可以使得多次驱动手柄无需主动切换推刀件的位置，即可顺利完成先夹持后吻合的操作。然而，对于具有多行程驱动的具有复杂连杆机构的吻合器，医生在操作自动切换的吻合器手柄时，只能通过按压次数和手感来判断推钉动作的完成和推钉片回复到位，而无法进行直观地观察，因此需要一种能够快速判断推钉动作完成情况的吻合器。An endoluminal stapler may typically include two elongated jaw members for grasping or gripping tissue, respectively. In some surgical staplers, one of the jaw members has a staple cartridge loaded with a plurality of staples arranged in at least two lateral rows, and the other jaw member has an anvil, where the staples exit from the staples When the staple cartridge is pushed out, the anvil defines a surface for forming the staple legs, and the stapling operation is accomplished by a cam member that acts on the staple pusher as it travels longitudinally through the staple cartridge, thereby The staples are sequentially ejected from the staple cartridge. A blade may travel between the staple rows for longitudinally cutting and/or opening the stapled tissue between the staple rows. In the prior art, the application number 202010732474.0 discloses a drive switching mechanism for a stapler and a stapler, specifically a stapler for laparoscopic surgery, with the differential control element, the handle can be driven multiple times without By actively switching the position of the pusher, the operation of first clamping and then anastomosis can be successfully completed. However, for a stapler with a multi-stroke drive with a complex linkage mechanism, when the doctor operates the automatically switched stapler handle, the doctor can only judge the completion of the push action and the return of the push piece by the number of pressings and the feel. Intuitive observation is impossible, so a stapler that can quickly judge the completion of the screw-pulling action is required.

When thepusher drive rod 42 is at the initial position, thestroke marker 43 is provided. 43 is located in the opening area corresponding to theobservation opening 31, and when the pushknife driving rod 42 is in the matching position, thestroke marker 43 is located outside the opening area corresponding to theobservation opening 31. It can effectively and intuitively judge whether the endoscopic stapler completes the screw-pushing stroke and completes the reset, which solves the technical problem that the endoscopic stapler with multi-stroke control cannot effectively determine the screw-pushing stroke.

本实施例中，行程标识件43为位于推刀驱动杆42侧面的凸起，在另一种实施例中，也可以是行程标识件43为位于推刀驱动杆42侧面的凹槽，或者是其他能够容易被识别的结构或者色彩。直接在推刀驱动杆设置行程标识件，可以直观地反应推刀驱动杆的行程完成情况，并且行程标识件的设置方式不会影响成体结构的布置。行程标识件43可以为单侧设置的一个，也可以为两个，两个行程标识件43对称设置在推刀驱动杆42两侧，观察开口31为两个，且分别与两个行程标识件43对应设置。In this embodiment, thestroke identification member 43 is a protrusion located on the side of thepusher driving rod 42. In another embodiment, thestroke identification member 43 can also be a groove located on the side of thepusher driving rod 42, or a Other structures or colors that can be easily identified. Directly setting the stroke marker on the pusher driving rod can intuitively reflect the stroke completion of the pusher driving rod, and the setting method of the stroke marker will not affect the arrangement of the integrated structure. Thestroke marker 43 may be one set on one side or two. The twostroke markers 43 are symmetrically arranged on both sides of thepusher driving rod 42, and there are twoobservation openings 31, which are respectively connected with the two stroke markers. 43 corresponds to the setting.
