[Experimental study of angiography using vascular interventional robot-2(VIR-2)].

Objective: To verify the feasibility and safety of new vascular interventional robot system used in vascular interventional procedures.

Methods: Vascular interventional robot type-2 (VIR-2) included master-slave parts of body propulsion system, image navigation systems and force feedback system, the catheter movement could achieve under automatic control and navigation, force feedback was integrated real-time, followed by in vitro pre-test in vascular model and cerebral angiography in dog. Surgeon controlled vascular interventional robot remotely, the catheter was inserted into the intended target, the catheter positioning error and the operation time would be evaluated.
