A laparoscopic stapler with an anti-retraction safety mechanism

Abstract

The invention discloses a laparoscopic stapler with an anti-retraction safety mechanism, which belongs to the technical field of staplers and comprises a gun body, a static grip and a dynamic grip. The gun body is provided with a control lever, and the lower surface of the gun body A static grip is fixedly connected, and a dynamic grip is connected to the lower surface of the gun body in rotation. The dynamic grip is located on the left side of the static grip. The static grip is provided with an anti-retraction mechanism, which is fixedly installed on the The lower surface of the gun body. In the present invention, by setting the anti-retraction mechanism, the moving handle will drive the positioning block to move, and the positioning block can adjust the position of the card slot when the positioning block moves, and at the same time, the positioning block no longer hinders the clamping rod, and the first spring passes through the The elongation of its own elastic force can push the lever to move downward, so that the lever is no longer inserted into the slot. At this time, the positioning block is no longer fixed and the dynamic grip is no longer fixed, so that the dynamic grip can Reset to work again.

Description

technical field [0001] The invention belongs to the technical field of staplers, in particular to a laparoscopic stapler with an anti-retraction 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. It is a device used in medicine to replace traditional manual suturing. Due to the development of modern technology and the improvement of production technology, the clinically used stapler is reliable in quality, easy to use, tight and suitable, especially its fast suturing, easy operation and There are few side effects and surgical complications, and it also enables tumor resection that was unresectable in the past. [0003] In the prior art, after the stapler is used, the dynamic ...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the dynamic grip cannot be fixed and tends to automatically rebound to the initial position after the stapler is used in the prior art, so that the doctor is likely to be confused when operating multiple staplers and will be reused In this case, it is easy to cause harm to the patient and affect the surgical effect. At the same time, the position of the joystick in the prior art cannot be adjusted, and its length is fixed and cannot be used well in different situations, which increases the difficulty of the doctor's operation. , and a laparoscopic stapler with an anti-retraction insurance mechanism is proposed
