Nerve microvessel pressure relief gasket imbedding device

Abstract

The invention discloses a nerve microvessel pressure relief gasket imbedding device which comprises a pushing-in body and a shell arranged on the pushing-in body in a sleeving mode. The shell is provided with a cylindrical separation portion section with the open front end. A channel allowing the gasket to pass therein is formed in the separation portion section. The pushing-in body is arranged to slide in the channel relative to the separation portion section till the front end face of the pushing-in body reaches the front end face of the separation portion section. On the one hand, the device can achieve the effect of a stripping device for separating nerves and vessels; on the other hand, the device can be used for imbedding the gasket. Accordingly, in operation, medical staff can completely operate the imbedding device with one hand, the nerves and vessels are separated, and the gasket is imbedded, so that the other hand is free to be used for using a sucker to suck cerebrospinal fluid, it is always ensured that the operation visual field is clear, operation apparatuses are prevented from being replaced frequently under a microscope, the operation time is shortened, and the pains of a patient are relieved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a nerve microvascular decompression gasket inserter. Background technique [0002] Facial muscle twitch, also known as hemifacial spasm, is a cranial nerve functional disease. During the onset, the hemi-facial muscles twitched involuntarily. The cause of the disease was that there were blood vessels compressing the facial nerve in the patient's cranium, and most of them were located in the branches of the anterior inferior cerebellar artery or posterior inferior cerebellar artery. [0003] At this stage, facial nerve root microvascular decompression is used. During the operation, a small incision is made behind the patient's ear on the affected side, a small hole is drilled into the skull, and the blood vessels that compress the facial nerve are found at the root of the facial nerve. After that, it is slowly pushed away from the root of the facial nerve, and a spacer, ...

AI Technical Summary

Problems solved by technology

Due to the movement of nerves and arteries during the operation, cerebrospinal fluid leaks out all the time, resulting in unclear vision and making the operation impossible

It is necessary for the medical staff to temporarily stop the operation of inserting the tweezers into the spacer, but to use the suction device to absorb the cerebrospinal fluid and frequently replace the surgical instruments, which will definitely prolong the opening time of the wound and increase the pain of the patient
