[0013] The nerve stripper is threaded to the tail tube at the rear end, the front end of the tail tube abuts against the rear end of the grip, and the tail tube is connected to a flushing hose. The hollow tail tube is connected to a hollow water channel.

[0014] The beneficial effects of this utility model are: 1. A hollow water channel is set inside the nerve dissector, and a tail pipe is connected to it. It can be connected to an external flushing hose to supply water from the head of the nerve dissector, which can play a flushing role and meet the flushing requirements of surgical operations. 2. The nerve dissector is inserted into the connecting rod section and gripping part of the handle and can extend and retract. The locking part of the extension adjustment head constrains the nerve dissector clamping section on both sides of the step within the adjustment channel and slides back and forth along the adjustment channel to meet the extension and retraction control of the nerve dissector. This allows for real-time adjustment during surgical operations to meet the dissection extension and retraction length adjustment for different nerve locations without the need to change to other length specifications of dissectors, facilitating surgical operations, reducing errors, and improving surgical safety. The push head adopts a hemispherical head corresponding to the encapsulation head to form an integral spherical structure, which facilitates blind pushing without missing the target area. Combined with its anti-slip grooves, ridges, and mesh, it further improves the convenience and safety of surgical operations. Attached Figure Description
