Abstract

Natural orifice translumenal endoscopic surgery (NOTES) is a minimally invasive procedure, known for its scar-less nature and short post operative recovery periods. A critical skill necessary for a NOTES procedure is the surgeon's ability to navigate and gain visualization of the target organ, which is done by moving the endoscope tip using the dials on the handle. We have developed an accurate and high resolution optical encoder based system to measure that dial manipulations, as part of a larger project to develop a VR-NOTES surgical simulator.
