Abstract
A powered prosthetic thigh can have a proximal portion configured to couple to a prosthetic hip socket and can have a distal portion attached to the proximal portion. The distal portion can have a distal connector configured to couple to a prosthetic knee. The powered prosthetic thigh can also have a computer controlled actuator configured to rotate the prosthetic thigh relative to the prosthetic hip socket.
Claims15
A powered prosthetic thigh, comprising:
- a proximal connector having a first end and a second end along a longitudinal axis;
- a proximal portion coupled to the first end of the proximal connector, wherein the second end of the proximal connector is configured to couple the prosthetic thigh to a prosthetic socket, wherein the prosthetic socket is configured to attach to an amputee and comprises a compliant member configured to deform, wherein deformation of the compliant member provides for relative lateral motion between the prosthetic socket and the powered prosthetic thigh;
- a distal portion attached to the proximal portion, the distal portion comprising a distal connector configured to couple to a prosthetic knee;
- and
- a computer controlled actuator mounted collinearly to the proximal connector along the longitudinal axis and configured to rotate the prosthetic thigh along a sagittal plane relative to the prosthetic socket attached to the amputee, wherein at least a portion of the computer controlled actuator is located proximally to the first end of the proximal connector.

A powered prosthetic hip, comprising:
- prosthetic socket configured to couple to an amputee, the prosthetic socket having a longitudinal axis;
- a proximal connector having a first end and a second end along the longitudinal axis, the second end coupled to the prosthetic socket;
- and
- a powered prosthetic thigh pivotably coupled to the prosthetic socket by the proximal connector, the powered prosthetic thigh comprising:
- a proximal portion coupled to the first end of the proximal connector, wherein the prosthetic socket comprises a compliant member configured to deform, wherein deformation of the compliant member provides for relative lateral motion between the prosthetic socket and the powered prosthetic thigh,
