A Survey on Surgical Robots and Key Technologies

Surgical robot is a research hotspot in medical robot area. In this paper, first we present the classification of surgical robots, including orthopedic robots, endoscopic robots, natural orifice robots, neurosurgical robots, vascular robots, and percutaneous robots; and elaborate their constructions, features and clinical application areas. Then we present the key technologies of surgical robots, including image navigation technology, master-slave control technology, etc. At last, we discuss the future development trend of surgical robots.
