Development of a laparoscopic illumination system inducing depth perception by a new intra-corporeal overhead illumination device

2010年，我们发明了一种新的腹腔镜照明系统，通过干箱模型的顶置照明产生阴影深度线索，用于腹腔镜训练任务。与传统照明系统相比，我们估计了新系统对腹腔镜任务性能的影响，并确定了新的腹腔镜照明系统显着提高了腹腔镜任务性能。随后，我们于2011年发明了一种用于腹腔镜顶置照明系统的新型照明装置。我们将该装置应用于不同科室的猪模型腹腔镜手术。在问卷调查中，外科医生评估了新的照明系统与传统照明系统相比，使腹腔镜手术更容易。

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.
