End actuator of surgical linear stapler

Abstract

The invention discloses an end actuator of a surgical linear stapler, and relates to the field of medical treatment. The end actuator comprises an end actuator body, wherein one end of the end actuator body is connected with a long rod; one side, far away from the end actuator body, of one end of the long rod is connected with a handle shell; a push-pull block is arranged on the outer wall of thehandle shell; a handle is arranged at the bottom of the handle shell; the end actuator body comprises a nail propping seat clamping plate connected to the end part of the long rod; the bottom of the nail propping seat clamping plate is connected with a connecting seat; one end of the connecting seat is connected with a nail propping seat; an anvil block is arranged on the inner wall of the nail propping seat; a nail bin is mounted in the nail propping seat clamping plate; and a nail bin cover is mounted at the top of the nail bin. The end actuator is simple and reasonable in structural design,safe and convenient to use and easy to operate; and through the structural design, a push plate staple is more convenient and efficient to trigger, and the stability during triggering of the staple is improved.

Description

Technical field[0001]The invention relates to the medical field, in particular to the end effector of a surgical linear 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 disposable or multiple-use staplers, imported or The domestic stapler is a medical device that replaces the traditional manual suture. Due to the development of modern technology and the improvement of production technology, the clinically used stapler is of reliable quality, convenient to use, tight and suitable for tightness, especially its fast suture , The operation is simple and there are few side effects and surgical complications, etc., and it also enables the resection of the tumor that could not be removed in the past.[0003]Surgical instruments include distal end effectors suitable for p...

Problems solved by technology

[0003] Surgical instruments include distal end effectors suitable for placement at desired surgical sites. These distal end effectors can engage tissue in a variety of ways in order to achieve diagnostic or therapeutic effects. Existing ends for surgical linear staplers The structural design of the actuator is relatively complicated, it is not easy to operate, and the firing efficiency and stability of the staples are not good
