Problems solved by technology

[0003] However, the driving rods of existing linear cutting staplers are all cylindrical, and the surface of the driving rod is moved by the friction of the driving mechanism. The driving mechanism and the driving rod are easy to slip off, which affects the firing effect and the service life of the stapler. Therefore, those skilled in the art provide a linear cutting stapler with a firing drive connection mechanism to solve the problems raised in the above-mentioned background technology

Abstract

The invention discloses a linear cutting anastomat with a percussion driving connecting mechanism, belongs to the technical field of anastomats, and is characterized in that the linear cutting anastomat comprises a shell, a fixing block is fixedly connected to the bottom wall of the inner bottom of the shell, a limiting sleeve is fixedly connected to the left side of the inner wall of the shell, an unlocking mechanism is fixedly connected to the bottom wall inside the shell, the opposite sides of the unlocking mechanism and the fixing block are fixedly connected with a percussion mechanism, the percussion mechanism penetrates through the shell and extends to the outer portion of the shell, and a connecting mechanism is arranged in the percussion mechanism, by arranging a driving mechanism, when the percussion block moves leftwards, the left side of a retaining plate is driven to abut against a tooth mark on a driving rod, therefore, the driving rod is driven to move towards the left side, the slipping phenomenon caused by reduction of the friction coefficient between the driving rod and the driving mechanism is effectively prevented, the percussion driving stability of the anastomat is improved, and the service life of the anastomat is prolonged.

Description

technical field [0001] The invention relates to the technical field of staplers, in particular to a linear cutting stapler with a firing drive connection mechanism. Background technique [0002] The endoscopic cutting stapler and its executive components suitable for minimally invasive surgery are a kind of staples that can be arranged in a straight line on the human tissue, and at the same time, the tissue between the staple lines is cut with a cutting knife. The cutting instrument is also one of the instruments widely used in minimally invasive surgery. It is mainly used for tissue resection, transection and anastomosis in open or endoscopic surgery of abdominal surgery, gynecology, pediatrics and thoracic surgery. [0003] However, the driving rods of existing linear cutting staplers are all cylindrical, and the surface of the driving rod is moved by the friction of the driving mechanism. The driving mechanism and the driving rod are easy to slip off, which affects the f...
