Abstract

The invention relates to the technical field of brain surgery assistant instruments and particularly relates to a fixing device for craniocerebral operation, and a using method of the fixing device. The fixing device comprises a device body, wherein the device body comprises a brain clamping mechanism used for brain clamping, a brain supporting plate mounted at the bottom of the brain clamping mechanism, and a brain tightening mechanism mounted at the top of the brain clamping mechanism. In the fixing device for craniocerebral operation and the using method thereof, by injecting water into a compass bar, the compass bar is deformed and expanded, the compass bar is clung to a brain outer wall, the traditional rigid support for fixing is avoided, damages to brain are reduced, meanwhile when tightly compressing the brain, the compass bar can receive a pressure feedback by the brain, the feedback pressure reacts on one side of the compass bar, so that the size of the compass bar can be adjusted automatically, fine adjustment on the compass bar is achieved, and the brain fixing effect is improved.

Description

technical field [0001] The invention relates to the technical field of brain surgery auxiliary equipment, in particular to a brain surgery fixation device and a method for using the same. Background technique [0002] With the rapid development of medical technology, various types of clinical interventional operations continue to be carried out. When the hospital performs human craniocerebral surgery, it is necessary to fix the patient's cranium to meet the needs of doctors when performing human craniocerebral surgery and prevent patients from The head shakes during the operation, ensuring the accuracy of the operation and improving the success rate of brain surgery. [0003] The existing cranial fixation devices are difficult to achieve all-round fixation of the cranium, resulting in unstable cranial fixation. At the same time, when fixing the cranium, it is often necessary to use a rigid bracket to be stuck on the cranium to complete the fixation. This method not only Unn...
