The accuracy, flexibility, and stability of surgical robot has been recognized by the medical community and the patients. Surgery robot has become an important method to achieve orthopedic surgery with the minimal invasiveness, digitization and intelligence. Orthopedic surgery has its own characteristics on surgical objective, surgical instruments, operating mode, and so on. Especially, the orthopedic surgical robot highly depends on the intraoperative navigation devices, which determines the technical specificity of orthopedic surgical robot and has broad clinical application. In this article, with the background of orthopedic surgical robot, we analyze and discuss the research situation of the orthopedic surgical robot and its navigation.
