Outline of Research at the Start

(A)いかなる施設でも実行 容易な簡便かつ安価なトレーニングシステムの構築
(B)同システムの質的評価(吻合における糸のバランス評価や模擬血管内治療におけるワイヤールートのシミュレーションなど)
(C)3Dプリンターを用いた医療画像からの三次元血管構築とその臨床応用
(D)リープモ ーションを用いた術者の手の動きの評価と臨床応用
(E)手技の動画を収集し、ディープラ ーニングによって状況に応じた至適な動作を場面ごとに追求する、の5点を主な課題とした。

Outline of Final Research Achievements

Various attempts have been made to construct a training system for surgeons. One was a method to objectively evaluate the suture outcomes in artificial vessel suturing. Next, we created a training system for endovascular treatment, using catheter track paths as an objective measure of proficiency. We also examined suture movements objectively and quantitatively using Leap Motion, a motion controller capable of 3D real-time tracking of the hand.

We recruited medical students to skilled trainees who had been post-graduates for more than 15 years. In each of the above cases, a steep learning curve was observed with training time, and it was shown that a medical student who was a complete novice at 10 hours was able to produce a score close to that of a vascular surgeon.

Academic Significance and Societal Importance of the Research Achievements

外科医のトレーニングはどのようなものをどのくらいの時間行うべきか。その答えはいままでなかった。今回様々なトレーニング方法とその成果の客観的評価を示すことができた。現在心臓血管外科専門医認定機構によって義務とされているトレーニング時間は30時間であるが、多忙な外科医にとって過大な負荷となっている。今回の10時間での高い成果を考慮し、この時間を減らす説得力のある根拠となると考えている。
