technical field

The invention relates to a fixing device, in particular to a neurosurgical head fixing device.

Background technique

Neurosurgery is a branch of surgery, which uses unique neurosurgery research methods to study the human nervous system, such as the brain, spinal cord and peripheral nervous system, as well as related diseases, based on surgery as the main treatment method. Subsidiary organs, such as skull, scalp, cerebrovascular meninges and other structural injuries, inflammation, tumors, deformities and certain genetic metabolic disorders or dysfunctional diseases, such as: the etiology and pathogenesis of epilepsy, Parkinson's disease, neuralgia and other diseases , and explore new diagnostic, therapeutic, and preventive technologies as a high-level, precise, and cutting-edge discipline. Neurosurgery mainly treats diseases of the brain, spinal cord and other nervous systems caused by trauma, such as cerebral hemorrhage that is life-threatening, brain trauma caused by a car accident, or brain tumor compression that requires surgical treatment.
