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.
