Description

Technical Field

[0001] The invention relates to the technical field of neurosurgery, and in particular to a neurosurgery head fixing device. Background Art

[0002] Neurosurgery is a branch of surgery. It is a high-level, sophisticated and cutting-edge discipline that uses unique neurosurgery research methods to study the human nervous system, such as the brain, spinal cord and peripheral nervous system, and its related ancillary structures, such as the skull, scalp, cerebral blood vessels and meninges, damage, inflammation, tumors, deformities and certain genetic metabolic disorders or functional disorders, such as the causes and pathogenesis of epilepsy, Parkinson's disease, neuralgia, etc., and explores new diagnosis, treatment and prevention technologies. Neurosurgery is mainly responsible for diseases of the brain, spinal cord and other nervous systems caused by trauma, such as life-threatening cerebral hemorrhage, brain trauma caused by car accidents, or brain tumor compression requiring surgical treatment.

[0003] During the operation, due to the different surgical positions of different patients, the patient's head will be deflected to a certain extent to ensure a suitable surgical angle. When the head is fixed alone, if the patient's body moves, it is easy to cause the head to move slightly and cause certain obstacles to the operation. Moreover, when the head is fixed by deflection alone, it is easy for the neck to be subjected to excessive force, causing physical discomfort to the patient and resulting in unstable head fixation.
