Novel head fixing device for cerebral angiography

Abstract

The invention discloses a novel head fixing device for cerebral angiography. The device comprises a bottom plate, a head fixing assembly and a jaw bone fixing assembly; a sponge pillow is arranged above the bottom plate; the two sides of the bottom plate are fixedly connected with side plates; the head fixing assembly is installed on the side plate; a sliding way is formed in the surface of the side plate; a movable plate is clamped in the sliding way; the jaw bone fixing assembly is installed on the movable plate; a first threaded rod penetrates through the bottom plate; and one end of the first threaded rod is fixedly connected with an extension rod. The novel head fixing device for cerebral angiography relates to the technical field of medical apparatus and instruments for radiography.The novel head fixing device for cerebral angiography is reasonable in design and simple to operate and is high in overall stability; the head of a user can be fixed according to the requirements of the user through cooperation of all the structures; more comfortable use feeling is provided for the user; it is avoided that the head shakes during radiography due to fatigue or tension of the user; and therefore, the radiography effect is affected, and the use requirements of the user are met.

Description

technical field [0001] The invention relates to the technical field of medical devices for radiography, in particular to a novel head fixation device for cerebrovascular radiography. Background technique [0002] Cerebral angiography is an X-ray examination technique that has been widely used clinically since 1990. It first selects an access artery, usually the right femoral artery, and places an arterial sheath through the right femoral artery. Select different catheters, under the guidance of the guide wire, select the artery to be displayed, and inject iodine-containing contrast agent. Continuous filming of the blood vessel trajectory passed by the contrast agent, and digital subtraction angiography (DSA) of cerebral blood vessels through electronic computer-aided imaging, can specifically understand the morphological changes of blood vessels, such as changes in course, distribution, displacement, thickness and circulation time Wait. It is of special value in the diagno...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a new type of head fixation device for cerebral angiography, which solves the problem that the patient cannot keep the head fixed during the cerebral angiography process, which affects the effect of cerebral angiography and causes calculation errors. It prolongs the inspection time, brings inconvenience to medical staff, and makes it difficult to meet the daily needs of users
