Abstract

The invention relates to medical equipment, in particular to a microvascular decompression device for facial spasm cranial nerve diseases. The microvascular decompression device comprises a movable bedplate and a fixing frame vertically fixed on the movable bedplate; a fixing ring is mounted in the fixing frame through bolts; a restraining assembly for fixing the head of a patient is arranged on the fixing ring, wherein a driving mechanism connected with the restraining assembly is arranged below the movable bedplate; the driving mechanism comprises a self-locking transmission structure and a rotating structure connected with the self-locking transmission structure and the restraining assembly; the adjusting structure drives the movable bedplate, the restraining assembly arranged on the movable bedplate and the driving mechanism to swing so as to adjust the head of the patient to a proper operation position, the self-locking transmission structure drives the rotating structure to rotate after adjustment, and finally the rotating structure drives the restraining assembly to move to fix the head of the patient; and therefore, the patient is prevented from vibrating in the operation process, and the self-locking transmission structure can ensure that the clamping force of the restraining assembly is not loosened.

Description

technical field [0001] The invention relates to a medical device, in particular to a microvascular decompression device for hemifacial spasm cranial nerve disease. Background technique [0002] Microvascular decompression is mainly used to treat trigeminal neuralgia. The treatment of hemifacial spasm is mainly divided into conservative treatment and surgical treatment. Conservative treatment mainly includes oral carbamazepine and intramuscular injection of botulinum toxin. [0003] Conservative treatment has a certain curative effect in the early stage of the disease, but the symptoms cannot be controlled in the later stage; surgical treatment is specifically to make a longitudinal straight incision behind the ear and inside the hairline on the affected side, make a hole in the skull, enter the cerebellopontine angle area under a microscope, and pass the trigeminal nerve. Explore the area, "loosen" all blood vessels and arachnoid cords that may cause compression, and isolate...
