Linear cutting anastomat

Abstract

The invention relates to a linear cutting anastomat for surgical operation, relating to the field of medical apparatus and instruments. The linear cutting anastomat comprises an anastomat body, as well as a percussion push rod and a closing push rod which are mounted in the anastomat body, wherein the front end of the percussion push rod is connected with a cutting anastomosis mechanism, the front end of the closing push rod is connected with a nail box assembly, a trigger is mounted in the anastomat body, the trigger is connected with the rear ends of the percussion push rod and the closing push rod through a drive connecting rod, a trigger resetting part is mounted in the anastomat body, and when the trigger is pulled for the first time, the trigger drives the percussion push rod and the closing push rod to move forwards; the linear cutting anastomat further comprises a switching mechanism, after the trigger resets after the first-time pulling, the switching mechanism enables the trigger to be switched to only act with the percussion push rod, and when the trigger is pulled again, through the switching mechanism, the trigger enables the percussion push rod to move forwards so as to drive the cutting anastomosis mechanism to perform percussion. The linear cutting anastomat has the beneficial effects that one trigger drives the percussion push rod and the closing push rod to operate, so that a plurality of clinical operations including closing, compacting and percussion of the linear cutting anastomat are gradually completed, the structures of the components are simplified, and the operation is simple and convenient.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a linear cutting stapler for surgical operations. Background technique [0002] The linear cutting stapler is currently a surgical instrument commonly used in general surgery, thoracic surgery, gynecology, and pediatric surgery. This type of product adopts the working principle of a stapler, and stitches the staples arranged in a straight line on the tissue to suture the incision of the organ or tissue during the operation. At the same time, use the cutting knife in the middle of the staple to remove the tissue or organs at the suture site. The linear cutting stapler has the characteristics of neat suture, beautiful incision, quick operation process, firm suture, good hemostasis effect, and good blood supply at the suture port. However, most of the linear cutting staplers currently on the market use such as Figure 15 The shown double-trigger structure is divided into a closi...
