Control device for controlling knee prosthesis of transfemoral amputee, has reference sensor for measuring gravity acceleration, and controller for determining position of tibia part of knee prosthesis according to position of femur

摘要

The device has a measurement device i.e. reference sensor (9), for measuring gravity acceleration, and a controller (10) for determining position of a tibia part (3) of a knee prosthesis according to position of a femur (2) given by a user. The reference sensor is placed at a level of the femur, and an angular sensor is placed at a lever of the tibia part. An electrical motor (7) is integrated into the knee prosthesis, and the controller receives angular information of the reference sensor and the angular sensor.
