Dragging hook fixator for neurosurgery department

Abstract

The invention belongs to the field of surgical instruments of the neurosurgery department, and discloses a dragging hook fixator for the neurosurgery department. The dragging hook fixator comprises afixator body, supporting rods, a fixing piece and a dragging hook, and the fixator body is of a U-shaped structure; several supporting rods are uniformly arranged at the lower end of the fixator body,the supporting rods comprise first connecting rods, second connecting rods, spherical connecting rods and first fastening bolts, and the upper ends of the second connecting rods are fixedly connectedwith the outer spherical surfaces of the spherical connecting rods; several fixing pieces of n-shaped structures are arranged and sleeve the fixator body from top to bottom, concave body structures are arranged on the inner end surfaces of the left and right ends of each fixing piece, and threaded holes are formed in the upper end surfaces of the fixing pieces; a dragging hook rod is of a rectangular structure, a rectangular through hole is formed in the middle of the dragging hook rod, and the dragging hook fixator for the neurosurgery department further comprises a second fastening bolt. The dragging hook fixator is simple in structure, the position of the fixator can be easily adjusted, and the fixator is applicable to the using of neurosurgery operations.

Description

technical field [0001] The invention relates to the technical field of neurosurgery instruments, in particular to a neurosurgery retractor fixer. Background technique [0002] 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, on the basis of surgery as the main treatment method. Related 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 of epilepsy, Parkinson's disease, neuralgia and other diseases and pathogenesis, and to explore new diagnostic, therapeutic and preventive technologies, which is a high-level, precise and cutting-edge discipline. It is mainly used to treat diseases of the brain, spinal cord and other nervous systems caused by trauma, such as cerebral hemorrhage t...
