Outline of Final Research Achievements

Children with congenital upper limb deficiency have a variety of defects, and there are few electric prosthetic devices that can be provided for each defect. In this study, we developed a compact and lightweight electric prosthetic device for children with congenital upper limb deficiency. By modularizing the electric hand, elbow, shoulder, and socket, and combining them with an operation system using distance sensors, we have realized the electric prosthetic device that can be used for all types of forearm, upper arm, and shoulder defects.

Academic Significance and Societal Importance of the Research Achievements

本研究では，電動ハンド，電動肘，電動肩，ソケットをモジュール化し，距離センサを用いた操作システムと組み合わせることで，前腕欠損，上腕欠損，肩欠損のすべてに対応可能な電動義手を実現した．電動義手はユーザが使用できるレベルに達しており，これまで適当な電動義手の存在しなかった先天性上肢形成不全児（特に上腕欠損と肩欠損）に対して，新たな義手の選択肢を提供できる．
