摘要：
PROBLEM TO BE SOLVED: To enable operation of opening and closing a terminal device, the operation being performed with the intuitive and simple operation based on the movement of the forearm remaining of a person with a forearm amputation oneself, different from a conventional non-electric body-powered upper extremity prosthesis for transmitting the movement of a scapula and a shoulder joint by wire, etc., and making the movement of the terminal device.SOLUTION: A non-electric body-powered upper extremity prosthesis is configured by including: an inside arm 101 with a socket 105 laid and attached on an amputation end Sa of a forearm Fa and an outside arm 120 laid thereon, disposed so that this inside arm may relatively be rotated in the circumferential direction, and attached to an elbow Ea or an upper arm. A gripper opening and closing mechanism is included which comprises a movement conversion mechanism for converting a rotational movement to the circumferential direction of the inside arm 101 to the outside arm 120, and opening and closing a gripper 150 of a terminal device 151. As a result of this configuration, a user can obtain a rotation of a socket 105 according to the rotation angle of the amputation end Sa to the elbow Ea by convolution of the forearm Fa of oneself, and can open and close the gripper 150 according to the rotation.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2016,JPO&INPIT【課題】肩甲骨や肩関節の動きを、ワイヤ等によって伝達して手先具の動きをさせる従来の非電動能動義手と異なり、前腕切断端者自身の残存している前腕の動きに基づく直感的、かつ簡易な動作で手先具の開閉動作ができるようにする。【解決手段】前腕Faの切断端Saに被せて取付けるためのソケット105を備える内側腕部101と、これに被せられ、この内側腕部が相対的にその周方向へ回転できるように配置され、肘Ea又は上腕に取付けられる外側腕部120と、を含む構成とし、外側腕部120に対する内側腕部101の周方向への回転運動を変換して、手先具151の把持部150の開閉を行う運動変換機構を含む把持部開閉機構を備えるものとした。この構成により、使用者は、自身の前腕Faの回旋による肘Eaに対する切断端Saの回転角に応じ、ソケット105の回転が得られ、その回転に応じて把持部150を開閉できる。【選択図】 図2
