| Outline of Final Research Achievements |
We have developed a Laparoscopic Overhead Illumination System (LOIS) for laparoscopic surgery using the novel illumination device developed through our previous joint research, which brings a three-dimensional and natural feeling to the surgical image. In 2020, we solved the problem of the increase in the temperature of the illumination device by developing a water-cooled circuit using a Peltier element. In 2021, the power supply unit and the water-cooled circuit will be integrated and the LOIS will be improved to include a safety mechanism to increase temperature. In 2022, 26 physicians from multiple departments and 14 medical students underwent comparative verification surgeries using the LOIS and Conventional Laparoscopic Illumination System (CLIS), and the results of a questionnaire survey showed that the LOIS was statistically significantly more highly evaluated than the CLIS. These results demonstrate the usefulness of the LOIS as a preclinical evaluation.

内視鏡外科手術は，キズが小さい，痛みが少ない，早い社会復帰ができることから，現在の医療には必須となっています．しかし，手術の難易度が高いことが問題です．今回の研究では，内視鏡外科手術において，最も重要な情報源である手術映像を，より美しく自然に見せられるよう，全く新しい内視鏡手術用照明装置を開発しました．この装置を使い，多診療科の外科医が，実臨床を想定しご献体や動物で手術を実際にしてみたところ，今の照明装置より手術がやりやすくなったという成果を得ることができました．この研究成果が，より安全に安心して内視鏡外科手術を受けていただけることに貢献できると考えています．
