| Research Abstract |
We invented a new laparoscopic illumination system producing shadow depth cues by an overhead illumination in a dry box model for laparoscopic training task in 2010. We estimated the impact of the new system for laparoscopic task performance compared to the conventional illumination system and identified that the new laparoscopic illumination system improved laparoscopic task performance significantly. Afterward, we invented a new illumination device for the laparoscopic overhead illumination system in 2011. We applied the device for laparoscopic surgeries by variant department of surgeons in a porcine model. In a questionnaire survey, the surgeons evaluated the new illumination system make it easier for laparoscopic surgery compared to the conventional illumination system.
