Experiment Study Of Vascular Interventional Robot With Remote Application

Background Robotic systems have been introduced as a useful method for surgicalprocedures,but in the field of vascular interventional therapy, the developmentrobotic system is slow.Objective The purpose of this study is to verify the reliability and security ofvascular interventional robot system used in angiography, by means of vitropreliminary experiments and animal experiments.Method To conduct the angiogram experiments of glass vessel model and animal byusing the Vascular Interventional Robot developed by Beijing University ofAeronautics and Astronautics and Navy General Hospital. The robot system includesthe console port (remote operation syetem), the assitant port (propelled and rotarysystem) and the hydraulic fixing device. The surgeon will control the robot remotelyto go forward and rotate in the glass vessels model and animal vessels, on the 3Doperation interface to reach the target vessels. Finally the operation time and successrate will be counted and evaluated.Result In the glass vessels model experiment, the catheter can enter various kindsof vessel models with inside diameter length more than 3mm and angle less than 90°.In the animal (adult dogs) experiments, the surgeon finished smoothly the angiogramof the renal artery, the vertebral renal and the arteria carotis communis, without anyoperative complications.Conclusion The angiogram by using Vascular Interventional Robot system is safeand reliable. It partly realizes the remote operation by the surgeon, and can meet thesimple requirement of angiogram. However, without the wire control system andforce feedback system, the robot still needs to be further improved to extend itsapplication in a bigger range.
