Description

Technical Field

[0001] The invention relates to the technical field of neurosurgery instruments, and in particular to a supporting device for neurosurgery cerebral angiography. Background Art

[0002] Angiography refers to the introduction of contrast agents into target blood vessels to visualize the target blood vessels, thereby achieving the purpose of diagnosis. Today's angiography usually refers to digital subtraction angiography, which refers to the technology of using computers to process digital image information to eliminate bone and soft tissue images and make blood vessels clearly displayed.

[0003] Cerebrovascular disease is usually divided into hemorrhagic cerebrovascular disease and ischemic cerebrovascular disease. Hemorrhagic cerebrovascular disease is usually cerebral hemorrhage and subarachnoid hemorrhage; ischemic cerebrovascular disease is usually cerebral embolism, transient ischemic attack and cerebral thrombosis. Due to the complexity of brain blood vessels, cerebral angiography equipment is needed in the clinical treatment of cerebral thrombosis. During cerebral angiography, the patient's head needs to be supported and positioned to avoid the displacement of the patient's head during angiography affecting the angiography or minimally invasive operation. The current angiography support device can only support the patient's head on both sides, which is prone to the positioning support being too tight or too loose, which not only reduces the patient's comfort, but also easily affects the progress of the operation.
