Abstract

The invention relates to the technical field of auxiliary instruments for the thoracic surgery department, in particular to a three-point locating type craniocerebral operation locating device. The device comprises a head fixing device used for fixing the head and a fixing installing assembly used for installing the head fixing device. According to the three-point locating type craniocerebral operation locating device, two clamping plates and a fixing belt fix the three surfaces of the head, three-point head fixing is achieved, and the head fixing effect is improved; the reactive force generated from bending of a clamping strip can make the clamping strip tightly fit the surface of the head, the head fixing effect is further improved, and the clamping stability of the head fixing device isimproved; a supporting rod pushes a connecting piece to shift integrally, the integral position of an adjusting box is adjusted, and an installing rod rotates in a rotation groove to adjust the integral angle of a connecting block; an internal threaded cylinder rotates in a swivel to adjust the inclining angle of a connecting base, the installing angle of the adjusting box is adjusted, and multi-angle installment is convenient.

Description

technical field [0001] The invention relates to the technical field of brain surgery auxiliary equipment, in particular to a three-point positioning positioning device for brain surgery. Background technique [0002] With the rapid development of medical technology, various clinical interventional operations continue to be carried out. When the hospital performs human craniocerebral surgery, it is necessary to use a craniocerebral surgery head frame to fix the patient's head to meet the needs of doctors when performing human craniocerebral surgery. It is necessary to prevent the patient's head from shaking during the operation, ensure the accuracy of the operation, and improve the success rate of brain surgery. [0003] However, the existing head frames for craniocerebral surgery mostly adopt two-point positioning for clamping and fixing, and because the head is elliptical, the stability is not enough when clamping, which affects the overall fixation effect. The frame canno...
