A surgical cutting stapler with rigid components

Abstract

The invention discloses a surgical cutting stapler with rigid components, belonging to the technical field of surgical cutting staplers, comprising a handle part, one side of the handle part is communicated with a shaking mechanism, and a connecting pipe is movably connected in the shaking mechanism, the The other end of the connecting pipe is hinged with a supporting nail bin, and the top of the supporting nail bin is hinged with a clamping nail, and the clamping nail and the outer side of the supporting nail bin are provided with a limit mechanism, and the outer side wall of the supporting nail bin is There are nursing facilities in the suite. In the present invention, the cutting seat and the supporting nail seat are removed from the jaws and the main body of the staple cartridge, and flexible gaskets are provided in the cutting seat and the main body of the staple cartridge in the jaws. The advanced cutting seat and supporting nail seat improve the fit ability, effectively avoid tissue damage caused by clamping, and can quickly disassemble the cutting group and the main body of the staple cartridge for suction and disinfection, which can significantly reduce the difficulty of disinfection and maintenance and meet the needs of continuous use.

Description

technical field [0001] The invention belongs to the technical field of surgical cutting staplers, in particular to a surgical cutting stapler with rigid components. Background technique [0002] During surgery, in order to better treat the wound, it is generally necessary to use a cutting stapler. The endoscopic cutting stapler can include an end effector that can move or articulate relative to the elongated shaft assembly. The actuator is usually configured to fix the tissue to be resected between the clamping devices, wherein the clamping device usually includes a structure configured to accommodate the staple cartridge, and the handle portion for operation is configured to control the clamping Closure of the device, and control to push the blade to cut and push the staples for suturing. [0003] In the prior art, surgical cutting staplers mostly use rigid components to support the end effector, but the rigid components have high anastomosis strength, which easily leads t...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the anastomotic strength of the rigid components is relatively high, which easily leads to secondary damage to the tissue. At the same time, the cleaning and maintenance of the rigid components is relatively inconvenient, resulting in low sustainable utilization. After suturing, it is necessary to shake the handle executive part repeatedly to drive the staple cartridge to disengage from the meshing part. However, if the shaking is large, it will affect the suture treatment of the external endoscopic wound, which is not conducive to the follow-up rehabilitation of the patient.
