Disposable linear stapler for intestinal end

Abstract

The invention relates to the technical field of staplers, and discloses a disposable linear stapler for the end of the intestinal tract, comprising a main body, the inner wall of the main body is fixedly connected with a support plate 1 and a support plate 2, and the support plate 1 penetrates and is slidably connected with a trigger Plate, the upper surface and the middle part of the lower surface of the firing plate are respectively provided with a clip bar and a rack, and the upper surface of the firing plate is fixedly connected with a T-shaped block at one end away from the support plate one. The present invention utilizes the mutual meshing of the worm gear and the worm, and the structure is simple and reliable, which can effectively avoid the situation of automatic reset after the positioning rod is pushed out; Under the action of the spring, it will quickly snap into the card bar, which effectively avoids the frequent locking and unlocking of the firing plate caused by adjusting the position during the process of firing and advancing. The automatic locking of the board during travel improves the safety during operation and reduces the probability of errors.

Description

Technical field [0001] The present invention relates to the field of stapler technology, specifically a disposable linear stapler at the end of the intestine. Background [0002] The stapler was the world's first suture and was used for gastrointestinal anastomosis for nearly a century, until 1978, when the tubular stapler was widely used in gastrointestinal surgery. Generally divided into disposable or multiple use of staplers, imported or domestic staplers. Due to the development of modern science and technology and the improvement of production technology, the stapler used clinically is of reliable quality, easy to use, tight and suitable, especially its advantages of fast suture, easy operation and few side effects and surgical complications. Staplers are medically used as an alternative to manual sutures, and the main working principle is to use titanium nails to dissect or anastomose tissues, similar to staplers. According to the scope of application, it can be mainly divid...
