Active bending system of anastomat

Abstract

The invention provides an active bending system of an anastomat, and belongs to the technical field of medical equipment. The active bending system of the anastomat comprises a nail abutting seat, a steering pull rod, an inner sleeve, a sleeve connector, an outer sleeve, a connecting piece, a steering control seat, a steering conversion seat, a steering connecting rod and a cutting mechanism, and is characterized in that the inner sleeve is arranged in the outer sleeve, for limiting other parts; the steering pull rod is connected to the right side of the inner sleeve and used for connecting the inner sleeve and the gun body inner assembly; the steering conversion seat is movably hinged in the steering pull rod and is used for pushing or pulling back the steering pull rod to move left and right; the steering connecting rod is arranged on the steering conversion seat and is used for connecting the steering power element of the gun body with the steering conversion seat and providing power for the turning function of the instrument. The steering system can realize fixed-angle turning or any-angle turning according to different structures or transmission systems of the gun body, can be flexibly adjusted, and can effectively improve the convenience, the flexibility and the stability of an operator.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to an active bending system of a stapler. Background technique [0002] The stapler is the first stapler in the world. It has been used for gastrointestinal anastomosis for nearly a century. It was not until 1978 that the tubular stapler was widely used in gastrointestinal surgery. It is generally divided into one-time or multiple-use staplers, imported or domestic staplers. It is a device used in medicine to replace traditional manual suturing. Due to the development of modern technology and the improvement of production technology, the clinically used stapler is reliable in quality, easy to use, tight and suitable, especially its fast suturing, easy operation and There are few side effects and surgical complications, and it also enables tumor resection that was unresectable in the past. [0003] The bending systems of linear cutting staplers on the market c...

Problems solved by technology

[0004] The object of the present invention is to provide an active bending system for a stapler, aiming at solving the problem that the bending system for linear cutting staplers in the prior art can be roughly divided into two types: one is an adaptive passive bending system manufactured for Johnson & Johnson. Turning system, a single-rod active turning system invented by Kehui Company, but the accuracy and stability of the turning angle of both turning systems are not good enough, which reduces the use experience of doctors and the efficiency and success rate of surgery.
