Outline of Final Research Achievements

For the purpose of application to commercially available forceps, the following steps were undertaken:
Measurement of organ elasticity and induction of gripping force: We developed a system that can measure the gripping force exerted by the surgeon and the elasticity of the target object solely by manipulating the forceps. A compact interference device weighing 15 g was designed, and an interference force of 8 N was generated using a motor-driven pneumatic mechanism. In in vivo experiments conducted on pigs, the setup time averaged 5 minutes.
Display and operation guidance of forceps: As a novel approach in our research, we explored a method to directly extract the position and orientation of the forceps from the camera image using deep learning. To achieve the goal of measuring and displaying the forceps' position using only equipment available in the operating room, we proposed a method employing monocular camera and deep learning to measure the forceps' position and orientation.

Academic Significance and Societal Importance of the Research Achievements

本研究は、高価な装置や大型のロボットシステムを使わないで、術者を主役としたアシスタントシステムであることが特徴である。よって、全自動で手術の主導権を握る訳ではなく、術者により安全な動作へと誘導する。その誘導法として、術者へ力を伝える触感的方法と画像を利用した視覚的方法を提示したことに意義がある。また、その対象が一般的に市販されている鉗子にも応用が可能であり、より良い技術を広く医療社会に貢献できるのも大きな意義であると思われる。
また、機械学習の対象を人間ではなく、カメラ画像から直接鉗子の位置姿勢を求める方向へと転換し、良い結果を得ることが出来たのも学術的に新しい試みとしての意義を持っている。
