[0002] As the name suggests, neurological interventional technology is used to treat neurological diseases. It uses intravascular catheters for diagnosis and treatment with the support of digital subtraction angiography systems. For patients undergoing neurological interventional treatment, many diseases that are difficult to treat clinically can be cured through interventional treatment.

[0003] However, in existing neurological interventional treatments, when fixing the catheter, tape is often used to directly limit the catheter on the skin for fixation. This method has a poor fixing effect. When using traditional catheter fixing devices, only catheters of a single diameter can be used. If a thinner catheter is used, the catheter will move, and the applicability is poor. When fixing the catheter, multiple catheters of different thicknesses cannot be fixed at the same time, and it is not convenient to install the device.

[0004] Therefore, it is necessary to provide a new catheter fixing device to solve the above technical problems. Utility Model Content
