Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, in particular to a head fixing and restraining device. Background Art

[0002] Cerebral angiography is a minimally invasive interventional procedure and a novel diagnostic technique with high resolution. It is primarily used to detect cerebral vascular stenosis and occlusion, moyamoya disease, aneurysms, and arteriovenous malformations, and is the gold standard for imaging small cerebral vascular lesions. DSA has higher diagnostic accuracy than contrast-enhanced CT angiography, is simpler to perform, and has a relatively wide range of applications. Patient head immobilization is particularly important during cerebral angiography. The patient's head movement can affect the doctor's procedure, resulting in deviations in examination results and image quality, significantly complicating subsequent treatment, diagnosis, and care. Existing DSA rooms lack effective head immobilization restraints. Nurses must manually restrain agitated patients under radiation exposure, which fails to provide adequate head immobilization. Furthermore, the head restraint cannot be adjusted according to the patient's height and requires the patient to be moved for adjustment, making it extremely inconvenient for critically injured patients.
