Title:
BODY-IMPLANTED MOTION ASSIST DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/008705
Kind Code:
A1
Abstract:
A body-implanted motion assist device (1) that sandwiches a hip joint (12) between a thigh bone (14) and a pelvis-side bone (15) at which movements, such as bending/stretching motions, that are centered on the hip joint (12) originate. A first string (28) and a second string (29) are strung over the front side and the rear side of the device. An assist-force-generating rotary actuator (24) is fixed to the pelvis-side bone (15). The rotary actuator (24) pulls the first and second strings (28, 29), and, as a result, pulling force that assists bending/stretching motions, etc. that are centered on the hip joint (12) is transmitted to a hip joint section. The present invention achieves a body-implanted motion assist device that can transmit necessary assist force to a joint of a human body without restricting the natural movement of the joint.
