Outline of Final Research Achievements

Surgical experience compensates for the decline in the sense of touch due to an improved ability to process visual information. Stochastic resonance (SR) is known to improve tactile sensation. In this study, we used this method to improve the tactile feedback in endoscopic surgery.
This method improved not only tactile sensation, but also improved clinical peformance in endoscopic surgery.
This technique has a potential to be a great help in establishing safer and high quality endoscopic procedures.
