A guidewire insertion device for trigeminal nerve interventional therapy in neurosurgery

Abstract

The invention discloses a guide wire inserting device for trigeminal nerve interventional therapy in a neurosurgery department. The guide wire inserting device comprises a guide wire, a heat conducting sleeve, a heat insulation inner casing, a heat insulation outer casing, a loading sheath and a lubricant cylinder body, wherein the rear end of the heat insulation outer casing is in threaded connection with an input cover; the rear end of the input cover is connected with a closed casing pipe; the guide wire is arranged in the closed casing pipe and the input cover in a penetrating manner; theinner part of the heat insulation outer casing is fixedly connected with the heat insulation inner casing; the heat conducting sleeve is arranged inside the heat insulation inner casing; the inner part of the heat conducting sleeve is arranged into a preheating cavity; the guide wire is arranged in the preheating cavity in a penetrating manner. The guide wire conveniently penetrates through the closed casing pipe, a sealing valve clack, the preheating cavity, a guide wire pipe, a lubricant cavity and the loading sheath in sequence and penetrates out; the penetrated guide wire is prehheated, sothat the condition that spasm is caused when the guide wire is inserted into a trigeminal nerve blood vessel wall is avoided; the surface of the guide wire is coated with a hydrophilic lubricant andis uniformly smeared by using a cotton coating layer, so that a good lubricating effect s realized in the inserting process of the guide wire.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a guide wire insertion device for trigeminal nerve interventional treatment in neurosurgery. Background technique [0002] Trigeminal neuralgia is the most common cranial nerve disease. It is mainly manifested by recurrent paroxysmal severe pain in the distribution area of ​​the trigeminal nerve on one side of the face. Trigeminal neuralgia is mainly manifested as forehead headache, orbital pain, and pain on one side of the face. The nature of the pain is mainly severe knife-like pain, which is difficult to bear. According to domestic statistics, the incidence rate is 52.2 / 100,000, females are slightly more than males, and the incidence rate can increase with age. Trigeminal neuralgia occurs mostly in middle-aged and elderly people, and the right side is more common than the left side. The disease is characterized by: In the distribution area of ​​the trigeminal nerve, s...

AI Technical Summary

Problems solved by technology

[0003] The etiology and pathogenesis of trigeminal neuralgia have not yet been definitively determined, and none of the theories can perfectly explain its clinical symptoms

At present, when the guide wire passes through, the vascular wall of the trigeminal nerve tends to spasm due to the cold sensation. Secondly, the lubricating layer on the surface of the guide wire is not sufficiently lubricated, which makes it difficult to insert the guide wire smoothly. Further application of lubricant, which cannot be done routinely due to the extremely fine diameter of the guide wire
