Abstract

The high-precision head fixing device comprises a fixing bin, a clamping type fixing mechanism, a rotary type clamping mechanism, a comfort level fine adjustment mechanism and an extrusion type fixing mechanism, the clamping type fixing mechanism is arranged in the fixing bin and used for fixing the neck, the clamping type fixing mechanism comprises a pair of adjusting blocks, and the adjusting blocks are arranged on the clamping type fixing mechanism. A clamping semi-ring is arranged on the adjusting block, a sliding rotating groove matched with the clamping semi-ring is formed in the fixing bin, the adjusting block is connected with a first motor, the first motor penetrates through the clamping semi-ring, and the first motor is connected with a torque sensor. Through the arrangement of corresponding mechanisms on the headrest, fixation of the head and the neck of a patient is improved, the possibility that the head and the neck of the patient shake is reduced, the definition of a contrast image is improved, meanwhile, the contrast accuracy is greatly improved, and the influence of a doctor on patient condition judgment is reduced.

Description

technical field [0001] The invention belongs to the technical field of cerebrovascular clinical technology, and in particular relates to a high-precision head fixing device and a headrest for cerebral angiography. Background technique [0002] Cerebral angiography is a new X-ray examination technology widely used in clinical practice. It is the application of iodine-containing contrast agent into the common carotid artery, internal and external carotid artery, and vertebral artery. Cerebral angiography is divided into conventional cerebral angiography and digital subtraction cerebral angiography (DSA). Digital subtraction cerebral angiography is currently widely used. [0003] At present, during cerebral angiography, in order to ensure the clarity of the angiography image, the patient needs to lie down and keep the head and neck fixed. However, the existing headrest has poor fixation effect and poor comfort. The patient often shakes the head and neck, which seriously reduce...
