Considering Skill Evaluation Indexes Using 3D Motion Information of Instruments in Training Environment for Endoscopic Sinus Surgery

抄録

Endoscopic sinus surgery (ESS) is a surgery that requires advanced skills such as the surgeon holding an endoscope with one hand and operating a surgical instrument with the other hand. Surgeons require daily training to ensure safe surgical performance of ESS because ESS was required the high-level surgical technique. In this study, we focused on the development of an objective and quantitative skill evaluation method without high-cost sensor devices in the ESS training environment. In this paper, we aimed to examine the evaluation indexes using three-dimensional forceps motion information including depth for the quantitative evaluation of techniques in ESS training. We used future based method (ORB-SLAM) for measuring the motion information of endoscope and forceps during the training task. We performed the training using a nasal bone model simulated the ESS environment by 18 otolaryngologists. We measured the 12 indexes for evaluating the endoscope and forceps operation. And we also compared the results between skilled and unskilled surgeons in each index. From the results, we confirmed no significant difference, but some indexes showed different tendencies between skilled and unskilled surgeons. We suggested that some indexes could have different tendencies between skilled and unskilled surgeons. Thus, we will examine the task content and continue to measure all the indexes during the training task by increasing the number of subjects.
