This book mainly describes the basic principles, basic knowledge and application of medical robots. The book includes the characteristics and classification of the medical robot, the key technology of medical robot and the engineering research of clinical application of medical robot. While expounding the basic principles and knowledge, this book pays attention to its clinical application research. From the research background, research significance, key technologies and typical examples, hospital service robot, neurosurgery robot, vascular intervention robots, laparoscopic robot, capsule robot, prostate minimally invasive interventional robot and breast minimally invasive interventional robot, orthopedic robot, rehabilitation robot, complete denture tooth-arrangement robot, orthodontic archwire bending robot and other medical robots are analyzed and described. On this basis, the development of medical robots is analyzed from the perspectives of policies and regulations, market, industry chain structure and technology. This book is suitable for researchers, senior undergraduate students and postgraduate students and industry practicing engineers in medical robots and biomedical engineering to consolidate the basic principles and knowledge and learn about the industry frontiers. And it also is suitable for clinicians to understand relevant engineering practices.
