Embodiment Construction

[0059] first reference figure 1 , the semi-actuated prosthetic knee joint 100 constructed according to the first embodiment of the present invention is connected to the remaining lower limb 110 of an above-knee amputee through an interface 111 . The semi-actuated prosthetic knee joint 100 includes, among other components, a thigh link 103 connected to a knee joint mechanism 107 and a lower leg link 105 connected to an artificial foot 108 . Knee joint mechanism 107 is used to flex and extend thigh link 103 and calf link 105 relative to each other in flexion direction 101 and extension direction 102 . A hydraulic torque generator 104 is used to generate torque between the thigh link 103 and the shank link 105 .

[0060] The semi-actuated prosthetic knee joint 100 also includes a hydraulic power unit 200 connected to the hydraulic torque generator 104 . Among other components, hydraulic power unit 200 includes a hydraulic valve circuit 204 hydraulically connected to torque gene...

Abstract

A powered lower extremity orthotic (100; 310), including a shank link (105; 305) coupled to an artificial foot (108; 301), a knee mechanism (107; 306) connected to the shank link (105; 305) and a thigh link (103; 307), is controlled by based on signals from various orthotic mounted sensors (122, 124, 126, 127) such that the artificial foot (108; 301) follows a predetermined trajectory defined by at least one Cartesian coordinate.
