AI Technical Summary

Technical Problem

The existing stapler is difficult to adapt to different lengths of nail cartridge components, resulting in a fixed firing distance and unable to meet different surgical needs, increasing the medical cost of patients and posing a risk of device damage.

Method used

By setting the rack non-full teeth and rack pad stops in the instrument body of the stapler, the function of setting different firing distances according to different nail cartridge components is realized.

Benefits of technology

This design makes the stapler suitable for different specifications of nail cartridges, and can set different firing distances according to different nail cartridge components, solving the problem that the short-stroke nail cartridge can continue to firing after reaching the tail end of the stroke, avoiding equipment damage and additional damage to the patient.

Abstract

The present invention discloses a stapler, comprising an execution component and an instrument body on which the execution component is installed, the instrument body comprising a shell, a firing handle pivotally connected to the shell, a rack, a rack paddle and a rack paddle baffle, the firing handle is connected to the rack through the rack paddle; the rack is an interval tooth shape, and is provided with an A tooth located at the extreme firing position of a first nail magazine and a B tooth located at the extreme firing position of a second nail magazine, there is no tooth structure between the A tooth and the B tooth, and the length of the first nail magazine is smaller than that of the second nail magazine; the rack paddle baffle is slidably connected to the shell, and the greater the length of the nail magazine installed in the execution component, the farther the rack paddle baffle is from the rotation center of the firing handle; therefore, it can be suitable for nail magazines of different specifications, and different firing distances can be set according to different nail magazine components, thereby solving the problem that a short-stroke nail magazine can continue to fire after reaching the end of the stroke, thereby avoiding damage to the instrument or additional harm to the patient.
