Problems solved by technology

[0005] The purpose of the present invention is to overcome the unreasonable locking method caused by the influence of thread locking on the imaging effect, the locking of the positioning hole on the scope of application, and the unrestricted degree of freedom of rotation of the patient's head in the existing fixation device for cardiovascular and cerebrovascular imaging. The problem of poor fixation effect, so as to realize a kind of real-time self-locking, good fixation effect of cardiovascular and cerebrovascular imaging fixation device and its use method

Abstract

The invention relates to the field of medical apparatuses and instruments, in particular to a heart and cerebral vessel radiography fixing device and a using method. The problems that in an existing heart and cerebral vessel radiography fixing device, the development effect is affected by thread locking, and the application range is affected by positioning hole locking, so that the locking mode isnot reasonable, and the fixing effect is poor due to the fact that the rotation degree of freedom of the head of a patient is not limited are solved. The heart and cerebral vessel radiography fixingdevice is characterized by comprising a fixing base, a head fastening support, a normal limiting column and a frontal limiting plate; the head fastening support is movably connected to the fixing base, the normal limiting column is fixedly connected to the fixing base, and the frontal limiting plate is movably connected to the normal limiting column. The heart and cerebral vessel radiography fixing device and the using method can achieve real-time self-locking and is good in fixing effect, and the fixing effect of the radiography fixing device is improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a cardio-cerebral angiography fixation device and a method of use. 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 small trauma, fast detection and relatively obvious results. In the angiography examination, through the developed image of the blood vessel, it can be judged whether there are lesion characteristics such as stenosis and plaque in the angiography blood vessel, and then the health level of the patient can be determined. Since the contrast agent is developed by X-ray irradiation, the slight move...
