Rensselaer researchers secure $2.7 million NIH grant to advance 'scarless' surgery

visually and using their sense of touch. The simulator's advanced haptic touch-feedback system feels like the real thing a physician cutting or manipulating tissue with the simulator will feel with their hands the lifelike toughness, sponginess, and resistance of virtual tissue.

De said the key challenges related to creating a NOTES simulator include developing realistic hardware interfaces, accurate computer models of multilayered hollow organs such as stomach and intestines, and realistic simulations for the interaction of flexible surgical tools with soft tissues in real time.

"The aim of this study is to overcome these preliminary challenges, and develop the first virtual reality NOTES simulator that is firmly based on physical experiments and surgical experience. The simulator must also be realistically responsive to physiological consequences of surgical complications," De said. "There's still much work to be done, and much validation, before we can think about using NOTES or our NOTES simulator in a clinical setting. But this study places us on the right path to advancing this promising, exciting new technology."

The first simulated NOTES procedure the researchers will tackle, De said, is an appendectomy.
