Outline of Final Research Achievements

High operability bone cutting robot and a system which judges the bone cutting temperature in real-time from the cutting parameters are developed to realize the semi-automatic knee arthroplasty.
Operability of the robot was improved because the motion of the entire robot due to frequent posture changes during bone cutting was reduced by separating the position and posture input mechanisms. Intuitive input is possible by the proposed mechanism.
Cutting temperature was measured to prepare the dataset while varying spindle speed, tilt angle and feed speed as a bone cutting parameter. Learning was conducted using the prepared dataset. It was possible to judge whether the cutting temperature is appropriate or not when the parameters are varied. The relationship between the threshold and decision accuracy was investigated.

Academic Significance and Societal Importance of the Research Achievements

ここで提案するような半自動型手術支援システムを実現することにより、高精度でしかも安全性が高い手術を行うことができるので、患者にとってベネフィットが大きい。また、骨の切削条件によって高温になるかどうかをシステムが自動的に判断してくれるので、術者にとってもベネフィットが大きい。本研究で実現している自動判定システムは他にも利用することが可能であり学術的な意義は大きい。また、半自動型の手術支援システムは認可を得る上で重要であり、医学的・工学的な意義は大きい。さらに、本研究で実現するような安全性が高く高精度な手術支援システムの実現は世界的にニーズが高く社会的な意義は大きい。
