Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a device for clinical cerebral angiography. Background Art

[0002] Cerebral angiography is a new X-ray examination technology widely used in clinical practice. It is a development technology that uses iodine-containing contrast agents to inject into the common carotid artery, internal and external carotid arteries, and vertebral arteries. Continuous DSA angiography is used to display the morphology, location, distribution and course of cerebral arteries, returning veins and venous sinuses at different times. Cerebral angiography is divided into conventional cerebral angiography and digital subtraction angiography (DSA). Digital subtraction angiography has the advantages of being simple and fast, with clear vascular images, selective filming and few complications. Therefore, conventional cerebral angiography has been replaced by digital subtraction angiography. Currently, femoral artery or radial artery catheterization is usually used for whole brain angiography.

[0003] When using the clinical cerebral angiography equipment of the prior art, the patient is basically placed on the angiography bed, and the angiography machine installed on the angiography bed is used to complete the angiography detection project. However, in actual use, in order to prevent the patient from moving his body subconsciously, a fixation measure for the patient's body is usually set on the angiography bed to ensure that the patient does not move around during the operation, but the fixation of the patient's brain is ignored, and the support treatment of the patient's neck is also ignored, so that the patient's head and neck are not stable enough during the cerebral angiography operation, which may cause certain safety hazards in subsequent detection.
