Abstract: Robotics in medical have made giant strides in past several decades with its widely use in various aspects. According to it’s function and usage, medical robots are classified into 7 types: neurosurgery robot, orthopedics robot, laparoscopic robot, vascular interventional robot, prosthetics and exoskeleton robot, assistive and rehabilitation robot and capsule robot. The functions, specifications, advantages and disadvantages of present typical commercially available medical robotics are surveyed. The current research foci, key technology and future trends of medical robotics are also discussed.

Key words: assistive and rehabilitation robot, capsule robot, laparoscopic robot, medical robot, neurosurgery robot, orthopedics robot, prosthetics and exoskeleton robot, vascular interventional robot
