A Novel Catheter Rotation Structure for Aseptic Environment of Interventional Surgery Robot

摘要

With the development of interventional robot, it can help doctor operate minimally invasive interventional procedures. Using interventional robots do not only solve the high-risk cervical spondylosis of interventionists, but also increase the stability and accuracy of surgery. Interventional robots are becoming more and more accepted by doctors. However, the problem of aseptic conditions when interventional robots are used to operate surgery is exposed. Medically, aseptic condition is considered as a necessary condition. This study proposes a more reasonable bevel gear structure scheme for the guide wire operator structure. The purpose is to eliminate the shortcomings of the previous robotic catheter rotation structure, and solve the problem of the surgical aseptic condition in the application of the interventional robot. We designed an experiment to verify the reliability of the novel catheter rotation structure. The experimental results show that the stability and accuracy of the guide wire operator using the bevel gear meet the requirements of interventional surgery, and the aseptic problem of the interventional robot in the operation has a significant improvement.
