A stapler that can be quickly unlocked or locked

Abstract

The invention discloses a stapler capable of quick unlocking or locking, which belongs to the technical field of medical appliances and includes an end effector. One end of the end effector is transmission-connected with a clamping mechanism. A holding handle and a moving handle are fixedly connected, and one side of the holding handle is transmission-connected with one side of the holding handle through an opening mechanism. In the present invention, when the moving handle moves, the first sliding sleeve can be driven to slide outside the first sliding bar, and when the moving handle drives the first sliding sleeve to slide outside the first sliding bar, the first sliding sleeve can provide The feedback of the movement amount, and the interval of the bumps are even, ensures the uniformity of the movement amount feedback, and the movement amount feedback conduction can effectively reduce the difficulty of operation, thereby significantly improving the movement stability of the mobile handle, effectively meeting the needs of anastomosis after surgery, and reducing the cost of surgery. The error is generated to meet the needs of use.

Description

technical field [0001] The invention belongs to the technical field of medical appliances, in particular to a stapler that can be quickly unlocked or locked. Background technique [0002] The endoscopic cutting stapler may include an end effector movable or articulated relative to the elongated shaft assembly, the end effector is generally configured to hold tissue to be resected between clamping devices, wherein the clamping The device usually includes a structure configured to accommodate the staple cartridge, and the handle portion for operation is configured to control the closing of the clamping device, and the control of pushing the blade to cut and push the staples for suturing. [0003] In the prior art, the stapler is generally driven by the gripping mechanism, and the limit capacity of the gripping mechanism is mostly fixed only by one layer of locking. However, after the locking mechanism is disengaged, the transmission handle end lacks a feedback mechanism, which...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is: in order to solve the problem that the limit ability of the holding mechanism is only fixed by one layer of locking, but after the locking mechanism is disengaged, the end of the transmission handle lacks a feedback mechanism, and it is impossible to feel the unlocking or locking of the end very well The amount of displacement affects the control operation during anastomosis, and a stapler that can be quickly unlocked or locked is proposed
