Cerebrovascular diseases have risen to the first cause of death and disability, and the demand for cerebrovascular diagnosis and treatment has increased. At present, the main means of cerebrovascular surgery are interventional treatment under DSA (Digital Subtraction Angiography) radiation and open surgery. Although interventional treatment under DSA radiation is also minimally invasive, it requires the use of radiation and contrast agents, which are harmful to patients and physicians to varying degrees. There is also a certain deviation between the actual situation of vascular lesions after DSA digital subtraction and the imaging situation. Open surgery is traumatic and slow to recover. Therefore, there is a great demand for treatment methods that do not require contrast agents and radiation and can directly view lesions without deviation. The cerebrovascular endoscopic catheter system can solve this clear clinical pain point, and the demand will continue to grow.
