Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical head fixation device. Background technique [0002] In ophthalmology or neurosurgery, the doctor needs to fix the patient's head first for the operation. If the head is not fixed firmly, it may affect the normal operation of the operation, and even cause great danger to the patient. Traditional fixing devices such as gypsum, splint and bandage are commonly used in nursing work at present, which have single function, inconvenient operation, poor fixing effect and troublesome use, and poor adaptability. [0003] In the prior art, a head immobilizer with the application number "201711305041.1" includes a main body of the immobilizer, a rubber shock-absorbing pad, a backing plate, a hair buckle, a fixing block, a head fitting pad, a medical non-woven fabric and a belt, the bottom of the main body of the fixer is provided with the rubber shock-absorbing pad, the top...

AI Technical Summary

Problems solved by technology

[0004] However, there are still obvious defects in its use: 1. The device mainly uses a strap to fix the patient's head, and the restraint is weak. A slight impact from the outside or a slight movement of the patient's own body will cause the head to deviate. 2. The device cannot be precisely adjusted and fixed according to the different head sizes of different patients, but can only be roughly fixed, and the scope of application is small
