End effector for surgical linear stapler

Abstract

The invention discloses an end effector of a surgical linear stapler, relates to the medical field, and comprises an end effector body, one end of the end effector body is connected with a long rod, and one end of the long rod is far away from the end effector One side of the body is connected with a handle shell, the outer wall of the handle shell is provided with a push-pull block, and the bottom of the handle shell is provided with a handle; the end effector body includes a nail-resistance splint connected to the end of the long rod, so The bottom of the nail anvil splint is connected with a connecting seat, one end of the connecting seat is connected with a nail anvil, the inner wall of the nail anvil is provided with an anvil, and a nail bin is installed inside the nail anvil splint, so A nail bin cover is installed on the top of the nail bin. The structure design of the present invention is simple and reasonable, safe and convenient to use, and easy to operate. Through the structural design of the present invention, the firing of the push plate staples is more convenient and efficient, and the stability when firing the staples is improved.

Description

technical field [0001] The invention relates to the medical field, in particular to an 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 one-time or multiple-use staplers, imported or Domestic staplers are used in medicine to replace traditional manual suturing equipment. Due to the development of modern science and technology and the improvement of production technology, the clinically used staplers are reliable in quality, easy to use, tight and suitable for tightness, and especially fast in suturing. , simple operation, few side effects and surgical complications, etc., also enables tumor resection that was unresectable in the past. [0003] Surgical instruments include distal end effectors suitable for placement...

AI Technical Summary

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
