腹腔鏡下手術トレーニングシステムの構築

―初心者のための視覚的アシストを利用した理想動作のトレース―

抄録

In this study, a training system of laparoscopic surgery for complete beginners is proposed, so that the trainees can experience an ideal forceps operation of ligation performed by skilled surgeon. The developed training system consists of a training screen and an evaluation screen. In the training screen, the ideal forceps operation of ligation performed by skilled surgeon is displayed as a guideline, and the trainee manipulates the forceps so as to follow the guideline. Then, similarity between the forceps operation performed by trainee and the ideal forceps operation is calculated on the basis of Euclid distance of the tracking error. In the evaluation screen, the similarity is displayed visually to let the trainee know the evaluation of his/her skill. Experiment was executed to verify an effectiveness of the proposed system.
