A laparoscopic cutting stapler with adjustable jaw direction

Abstract

The invention discloses a laparoscopic cutting stapler with adjustable jaw direction, which relates to the technical field of staplers, and the main points of the technical solution include that a guide rod end is provided on the inner side of the rod port, and the guide rod end There are inner tube ports on the left and right sides, the rear end of the connecting rod port is connected with an adjustment end shell, a steering knob is placed above the adjustment end shell, and a fine-tuning knob is arranged on the right side of the adjustment end shell. A rotating shaft disc is fixed on the front side of the inner rotating shaft ring, and the rotating shaft disc and the inner rotating shaft ring are adhesively connected, and a rotating disc hole is provided in the middle of the rotating shaft disc, and a communication structure is formed between the rotating disc hole and the rotating shaft disc , a guide wheel is arranged under the front side of the turntable hole, and a rotating structure is formed between the turntable hole and the guide wheel. This structure restricts the springback of the structure by engaging, so that the adjustment structure can be fixed in time when the rotation stops, and at the same time, it can be reset by pushing the button with one key to facilitate use.

Description

technical field [0001] The invention relates to the technical field of staplers, in particular to a laparoscopic cutting stapler with adjustable jaw direction. Background technique [0002] Laparoscopic stapler (endoscopic cutting stapler and disposable nail box) is one of the important instruments in laparoscopic surgery. It replaces traditional manual suture and uses titanium nails to separate or anastomose tissues. It is easy and fast to operate and greatly The operation time is shortened. The laparoscopic stapler makes the operation field narrow, and the manual anastomosis of deep parts is easy, accurate, firm and reliable, and significantly reduces the incidence of anastomotic leakage. The stapler is a medical device that replaces manual suturing. The main working principle is to use titanium nails to separate or anastomose tissues, similar to a stapler. According to the scope of application, it can be divided into skin staplers, digestive tract (esophagus, gastrointe...

AI Technical Summary

Problems solved by technology

According to the scope of application, it can be divided into skin staplers, digestive tract (esophagus, gastrointestinal, etc.) circular staplers, rectal staplers, circular hemorrhoid staplers, circumcision staplers, blood vessel staplers, hernia staplers , lung cutting stapler, etc., the adjustment mechanism of the existing stapler is not perfect enough, there are connecting components that are shared and cannot work alone and cannot be used after being damaged, it takes a long time to adjust the required angle, and the adjustment accuracy is low. Manual reset and other issues

[0003] After searching, the Chinese patent discloses a laparoscopic cutting stapler with adjustable jaw direction (publication number CN201610105017.2). This patented technology has a simple structure, and the hand feeling of operating the joint knob is lighter and softer. There are more gears and a small span, and it can ensure that the jaws can cut thick tissues in the turning state. The joint adjustment mechanism of the endoscopic cutting stapler is effectively positioned and locked. The deflection structure is not easy to adjust for small angles. Therefore, those skilled in the art provide an endoscopic cutting stapler with adjustable jaw direction to solve the problems raised in the above-mentioned background technology
