A Novel Guide Wire Rotation and Delivery Structure for Interventional Surgical Robot

Abstract

In recent years, with the development of vascular interventional surgery robots, the use of surgical robots for angiography surgery has begun to be accepted by more and more doctors. With this tool, the doctor can operate the catheter and guide wire several meters away from the patient to complete the operation, which greatly reduces the radiation received by the radiologist and protects the doctor’s health. However, the traditional interventional surgery robot still has the following problems. Because the guide wire surface is too smooth, when encountering resistance, the guide wire is easy to slide, resulting in the reduction of the accuracy of guide wire rotation and delivery. The guide wire rotation and delivery mechanism of traditional interventional surgery robots are connected with the robot body, and the sterile environment is not completely realized. In this study, a new guide wire rotation and delivery transmission device is proposed, which can improve the accuracy of guide wire rotation and delivery without damaging the guide wire. Through experiments, we have verified that the guide wire rotation and delivery device meets the functional integrity and the accuracy of the guide wire delivery function. The experimental results show that the accuracy of the guide wire rotation and delivery transmission device can meet the requirements of vascular interventional surgery.
