Neuro-intervention head-neck fixing device

Abstract

The invention discloses a neuro-intervention head-neck fixing device. A head fixing plate can be movably installed on a supporting plate, a left splint is movably installed at the upper portion of the left side of the head fixing plate, a right splint is movably installed at the upper portion of the right side of the head fixing plate, a first tightening device and a second tightening device are both installed at the left side of the left splint in a front-back spaced mode, both the first tightening device and the second tightening device comprise shells, guide rods, slide rods, ratchet bars, and ratchets, a lifting device controls the slide rods to move up and down, the slide rods are slidably connected with slide blocks, the slide blocks are rotatably connected with connecting rods, the lower portions of manipulating rods are rotatably connected with the connecting rods, the ratchet bars are in slidably connected with the guide rods, the rackets are arranged at the lower portions of the slide blocks and are matched with the racket bars, the lower portions of the racket bars are fixedly connected with winch racks, the lower portions of the winch racks are meshed with winch gears, and shafts of the winch gears are provided with winches. The neuro-intervention head-neck fixing device is high in safety and reliability, the risk of occurrence of head dislocation of a patient in a neuro-interventio operation is drastically lowered, which is conducive to improvement of the curative effect of the operation.

Description

technical field [0001] The invention relates to the technical field of medical auxiliary equipment, in particular to a nerve intervention head and neck fixation device. Background technique [0002] Neurointervention is widely used in modern medicine because of its minimally invasive, safe, and low-complication features. In neurointerventional operations, local anesthesia or intravenous anesthesia is basically used, because patients have different tolerance levels to anesthetics. During the operation, the patient's head movement will cause the quality of cerebral angiography images to decrease, increase the risk of misdiagnosis and missed diagnosis, and increase the risk of vascular damage or perforation during the operation. Especially when stents for embolization of aneurysms and arteriovenous malformations with stenotic blood vessels are implanted, the movement of the patient's head will cause serious complications such as false embolization or stent dislocation, causing ...

AI Technical Summary

Problems solved by technology

During the operation, the movement of the patient's head will reduce the quality of cerebral angiography images, increase the risk of misdiagnosis and missed diagnosis, and increase the risk of vascular injury or perforation during surgery.

Especially in the embolization of aneurysm and arteriovenous malformation, the movement of the patient's head will cause serious complications such as embolism or stent dislocation, which will cause irreparable and huge damage to the patient, and even endanger the patient's health. patient's life
