Description

Special screw holder of neurosurgery

Technical Field

The invention relates to a medical instrument, in particular to a special screw clamp holder for neurosurgery.

Background

Neurosurgery is a branch of surgery, and is a branch of surgery, which is based on surgery as a main treatment means, and is used for researching the injury, inflammation, tumor, deformity and certain genetic metabolic disorders or dysfunctional diseases of human nervous systems, such as brain, spinal cord and peripheral nervous systems, and related auxiliary mechanisms, such as skull, scalp, cerebral vessels and meninges, by using a unique neurosurgical research method: the etiology and pathogenesis of epilepsy, Parkinson's disease, neuralgia and other diseases, and explores a high, precise and advanced discipline of new diagnosis, treatment and prevention technology. Neurosurgery is mainly used for treating diseases of nervous systems of brain, spinal cord and the like caused by trauma, such as life threatening due to cerebral hemorrhage and bleeding amount, brain trauma caused by car accidents, or operation treatment required by brain tumor compression.

The best technology adopted by neurosurgery to treat diseases at present is a robot brain stereotactic technology, and stereotactic surgery is to establish a brain coordinate system and install a stereotactic instrument on a skull by applying a stereogeometric coordinate principle, establish the coordinate system, position a brain target structure, and guide an operation manipulator (such as a microelectrode, a biopsy needle, a damaged needle and the like) into a target spot for operation. Wherein the stereotactic orientation is subdivided into: the three-dimensional directional operation, the three-dimensional fixed internal radiotherapy and the three-dimensional directional photodynamic therapy are the conversion results of national 863 scientific research projects, wherein the three-dimensional directional photodynamic comprehensive therapy is considered by the founders in Qinhai, compared with the traditional craniotomy, the three-dimensional directional photodynamic operation greatly reduces the operation risk and pain of a patient, is a minimally invasive operation, has the characteristics of accurate positioning, high operation precision and the like compared with the three-dimensional directional operation with a frame brain, can complete the operation in a waking state, can be discharged 3-5 days after the operation, and does not leave scars.

The existing neurosurgical treatment comprises clinical operation treatment and nursing treatment, particularly when intracranial neurosurgical treatment is carried out, skull cap bones need to be fixed, generally, the skull cap bones are fixed through an auxiliary steel plate and special screws, and due to the fact that the screws are small in size, doctors cannot clamp the skull cap bones conveniently when using the screws, so that the skull cap bones cannot be fixed quickly and accurately, and the existing using requirements cannot be met.
