Outline of Final Research Achievements	For evaluation of junior doctor’s surgical skill, we developed a quantitative analysis method of surgical instruments operation using a navigation information. The motion of endoscope and forceps during ESS are tracked, then quantify operation by several parameters such as speed, density, rotation, distance and angle between endoscope and forceps. This method is considered useful for authorization of surgical skill in the future.
Academic Significance and Societal Importance of the Research Achievements	ESSにおける術者の技量を別の尺度から客観的に定量評価し、さらに術者ごとの手技的な特徴や改善すべき点を明確に提示、フィードバックできるシステムを構築する。ナビゲーション情報を利用して術者のESS手技・技術を定量的に様々な因子をもって解析することで、安全かつ適切なESS技術を担保するための内視鏡と鉗子動作の客観的評価方法の確立に結び付けることができる。
