Embodiment

[0042] Hereinafter, the present invention will be described in further detail through examples.

[0043] The structure of the microcatheter in this embodiment is as follows: the storage bag is made of cellulose, the decompression pad is made of medical-grade pure polytetrafluoroethylene, and the development mark is ferric iron tetroxide with magnetism, which can also be used for both action and release. The joint part of the mechanism connection, the release mechanism realizes the combination and separation of the storage bag and the guide wire through the principle of magnetic adsorption.

[0044] The operator controls the release switch (7), and the part with a magnet inside transmits the magnetic field to the front end of the guide wire through the proximal end of the guide wire, and combines with the magnetic bonding part at the end of the reservoir (with a decompression pad inside), After being combined with the storage bag, slowly push it to the affected part, and then o...

Abstract

The invention provides a microcatheter for microvascular nerve decompression. The microcatheter includes a storage bag (1) sequentially from the distal end to the proximal end in its length direction, and is connected with the storage bag (1) in a detachable manner. The release mechanism (4) and the release switch (7) controlling the release mechanism, the storage bag has a decompression pad (2). When the microcatheter for nerve decompression of the present invention is used for microvascular nerve decompression, it has excellent effects such as no need for craniotomy, low risk, small minimal trauma, rapid operation, short recovery time, preservation of nerve function and high long-term curative effect. .

Description

technical field [0001] The invention relates to a medical device, in particular to a microcatheter for microvascular nerve decompression. Background technique [0002] Facial muscle twitch, also known as hemifacial spasm, is a cranial nerve functional disease. During the onset, the hemifacial muscles twitched involuntarily. The cause of the disease was that the nerves in the patient's cranial memory area were compressed by blood vessels, and most of them were located in the branches of the anterior inferior cerebellar artery or posterior inferior cerebellar artery. [0003] Trigeminal neuralgia is the most common cranial nerve disease. It is mainly manifested as recurrent paroxysmal severe pain in the distribution area of ​​the trigeminal nerve on one side of the face. The incidence rate in domestic statistics is 52.2 / 100,000, and women are slightly more than men. Middle-aged and elderly people, and the incidence rate increases with age. The disease is characterized by unb...
