Abstract

The invention discloses a head fixing device for cerebral angiography. The head fixing device comprises a base and a boss fixed on the base, wherein a supporting plate which can move up and down is insliding connection to the upper end surface of the base through a spring, and a curved concave part for bearing the head is arranged on the supporting plate; side limiting plates which are in slidingconnection to the base are symmetrically arranged on two sides of the supporting plate; a first screw rod in threaded cooperation with the side limiting plate is arranged in the base and is driven bya first motor to rotate so as to drive the side limiting plate to make the same-direction movement or opposite-direction movement, and an air sac is arranged on one side close to the supporting plate, of each of the side limiting plates; and when the side limiting plates make opposite-direction movement and are close to the supporting plate, the air sacs can press the head on the supporting plate, and when the pressure born by the air sacs is higher than a set value, a sensor is used for controlling the first motor to stop working.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a head fixation device for cerebral angiography. Background technique [0002] Cardiovascular and cerebrovascular diseases mostly occur in middle-aged and elderly people, and have high morbidity, mortality and disability rates. With the acceleration of the aging society, cardiovascular and cerebrovascular diseases have become the number one killer threatening human health. Cardiocerebral angiography is widely used in clinical practice due to its technical characteristics of less trauma, quick detection and relatively obvious results. In the angiography examination, it is possible to judge whether there are lesion characteristics such as stenosis and plaque in the angiography blood vessel through the developed image of the blood vessel, and then determine the patient’s health level. Since the contrast agent is developed by X-ray irradiation, the patient’s blood pressure du...
