A Surgical Navigation and Endoscope Holder Integrated System for Sinus Surgery

In this paper, we developed an integrated system, which consists of an augmented reality-based surgical navigation system (ARSNS) and an endoscope-holder system (EHS) to reduce complications such as blindness, cerebrospinal fluid leak and to solve a constraint on hand movement of surgeons during sinus surgery. The proposed system provides following main functions: warning system, automatic transparency adjustment, magnetic brakes, and counter-balancing mechanism. In addition, the system compensates for AR error which increases with the rotation of the scope cylinder. For the evaluation of ARSNS and EHS, the phantom experiments were performed with surgeons. Through the experiments, surgeons found the proposed system will be effective in performing sinus surgery
