骨関節手術支援ロボット

抄録

Computer assisted surgery systems such as preoperative planner, surgical navigation, and surgical robot have been recently introduced in some orthopaedic field. To overcome the inaccuracy of hand-controlled positioning of surgical tools even under navigational guidance, three robotic systems have been developed. One type directs a cutting guide block or a drilling guide sleeve, with surgeons sliding a bone saw or a drill bit through the guide instrument to execute a surgical action. Another type constrains the range of movement of a surgical tool held by a robot arm such as ACROBOT. The last type is an active system, such as ROBODOC or CASPAR, which directs a milling device automatically according to preoperative planning. These CAS systems, their potential, and their limitations are reviewed here. Future technologies and future directions of CAS that will help provide improved patient outcomes in a cost-effective manner are also discussed.
