Technical Field

[0001] The utility model relates to the technical field of medical auxiliary equipment, in particular to a head support for neurointervention surgery. Background Art

[0002] As the name suggests, neurointerventional technology is the treatment of neurological diseases. It uses intravascular catheter operation technology with the support of digital subtraction angiography (DSA) system to diagnose and treat lesions involving the human neurovascular system through specific methods such as selective angiography, embolization, dilation and shaping, mechanical removal, and drug delivery. Since the cranial nerves are located in the skull, the patient's head needs to be fixed before neurointerventional surgery to keep the patient's head still during the operation to ensure the smooth operation. Among them, the "A Neurointerventional Surgery Head Support" disclosed in the application number "202121863356.X" has solved the technical disadvantages of restricting the patient's head from raising his head, causing the patient to feel foreign body discomfort during use, and prone to pressure sores. However, in actual use, a neurointerventional surgery head support with a similar structure still has many defects, such as compressing the auricle, causing insufficient blood supply to the auricle, causing discomfort to the patient's auricle, and flexible clamping can cause slight deviation of the head, which can easily affect the safety of the patient's neurointerventional surgery. Therefore, it is necessary to design a neurointerventional surgery head support. Utility Model Content
