| Outline of Final Research Achievements |
We proposed the concept of surgical grasping forceps with enhanced sensorimotor capability based on attaching a vibrator to the forceps' grip by evoking a stochastic resonance (SR) effect. The experiments conducted with the proposed forceps showed that maintaining the noise intensity within the optimal range could improve tactile sensitivity, and confirmed the usefulness of the SR application for medical devices. We also developed a haptic display system to render the force response of a viscoelastic object that considers the applications to a laparoscopic surgery training with the HER method was developed. The results of evaluation experiments showed that the displayed force by the proposed HER method can provide closer haptic feeling to the target object than that generated by the mass-spring model.
