Surgical navigation systems allow surgeons to obtain precise guidance to a target region in a surgical procedure and to recognize real-time anatomical information from a surgical field in three dimensions. However, with existing navigation systems, it is difficult to gauge precisely in real time the distance between a surgical tool and organs inside a patient's body from the navigation display. Therefore, we developed a novel navigation method with “distance sensation” using correlation distance maps generated around organs and surgical tools. In this study, we focused on tactile sensations that can be directly passed on to surgeons, and developed a force-feedback-based surgical navigation system with distance sensation for surgical robotics. We compared the performance of this navigation system to that of visual feedback systems and sound feedback navigation systems. The results show that force-feedback-based navigation enhances the accuracy and safety of surgical procedures.
