A tubular stapler with a safety mechanism

Abstract

The invention discloses a tubular stapler with a safety mechanism, which includes a stapler main body and an enlarged display mechanism. The front and rear sides of the lower end surface of the stapler main body are respectively fixed with a first convex plate and a second convex plate. A safety plug runs through the firing handle, and the enlarged display mechanism is snapped and connected to the top of the stapler main body. The tubular stapler with a safety mechanism, before using the device, the safety plug part is in the first convex plate, the second moving push rod part is in the firing handle, and the firing handle is snap-connected to the first convex plate Between the safety bolt and the second convex plate, the safety bolt is in the closed state, and the firing handle cannot be rotated, so as to achieve the effect of safety, only the safety bolt, the first moving push rod and the second moving push rod are pushed backward as a whole to make the safety bolt, The firing handle can only be used normally after the first moving push rod and the second moving pushing rod are completely in the firing handle, the first convex plate and the second convex plate respectively, and the safety catch is in an open state at this moment.

Description

technical field [0001] The invention relates to the related technical field of staplers, in particular to a tubular stapler with a safety mechanism. 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. , easy operation, few side effects and surgical complications, etc., and it also enables the resection of tumors that were unresectable in the past. The stapler is a medical device that replaces man...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a tubular stapler with a safety mechanism to solve the problem that the existing tubular stapler proposed in the above background technology has no safety mechanism, is prone to misoperation, and has insufficient anti-slip effect. If the device slips off from the hand, it will affect the normal operation of the operation, and at the same time, the observation effect of the firing index is poor.
