Description

Nerve intervention head and neck positioning operating table under DSA machine

technical field

The invention relates to the field of medical instruments, in particular to an operating table for head and neck positioning under a DSA machine.

Background technique

DSA machine, also known as digital subtraction angiography machine, is mainly used for general X-ray examination, angiography examination and interventional therapy.

With the improvement of the performance of digital subtraction angiography equipment and the maturity of interventional technology, neurological intervention has become a technique vigorously developed by neurology, neurosurgery, and radiology departments of major hospitals in the world due to its advantages of small trauma and rapid recovery. It mainly includes whole brain angiography, recanalization and shaping treatment of ischemic cerebrovascular disease, embolization treatment of hemorrhagic cerebrovascular disease, etc. Therefore, in the interventional diagnosis and treatment operations of major hospitals, the proportion of neurological interventional diagnosis and treatment operations is very large. In order to obtain a clear and accurate head DSA image and perform interventional surgery, it is very important to fix the head and neck of the surgical patient, which is related to the success or failure of the surgery. In actual operation, most neurointerventional operations use local anesthesia or intravenous anesthesia. Due to the different tolerance levels of patients to anesthetics, under the stimulation of contrast agents, disturbance of consciousness, dizziness, aphasia, and incomprehension of doctor's instructions will occur. The patient's head and neck will move, so the image will be blurred and distorted during DSA imaging, which is not conducive to diagnosis.
