The disclosure discloses a universal robot for interventional angiographic surgery and interventional therapeutic surgery. The robot meets the needs of both angiographic surgery and therapeutic surgery, which facilitates the clinical use. The robot is universal for both angiographic surgery and interventional therapeutic surgery, with advantages of simple structure, good stability, modular structure design, and so on, which is suitable for operation environment. By measuring the push and pull force of the micro force sensor at the driving end, the change of the axial friction force of the guide wire is judged, which gives the doctor timely reminder and protects the safety of patients. According to the feedback value of the high precision load cell at the driven end, the clamping degree of the guide wire is adjusted at any time to ensure there is no slipping phenomenon, which meets the needs of vascular interventional surgery.
