| Outline of Final Research Achievements |
With the recent trend towards minimizing surgical invasiveness, it has become crucial for surgeons to understand the three-dimensional structure of peripheral tissues in the endoscopic field and to predict the risk of damaging unseen vessels and nerves. In this study, we developed anatomical teaching materials based on real images that can be learned using binocular stereoscopic vision and the surgeon’s free line of sight. The created real-image-based layered anatomy content can be played back on devices such as spatial reproduction displays and VR goggles. We successfully created teaching materials that allow for the retrograde reconstruction of human structures, which is impossible in actual training, using images similar to those used in clinical training with anatomical specimens.

手術の技術向上には献体を用いた解剖トレーニングが最適であるが、貴重な献体を用いたトレーニングの機会は決して多くはなく、そもそも大学病院でない場合は解剖のトレーニング自体ができない場合もある。さらにその解剖も一度解剖をしてしまうと後戻りができず、一度進めてしまった手順を振り返ることはできない。貴重な献体の解剖結果を有効活用するため予めにも手術手技をくりかえし学習する手段が重要になる。本研究プログラムの成果は従来の解剖による学習より、より少ない経験でも知識の習得の促進が可能であり、解剖する機会が少ない医師のみならず、解剖の機会がない医師への教育効果も期待される。
