Actuated prosthesis for amputees
First Claim
1. An actuated prosthesis for replacement of an amputated limb, the prosthesis comprising:
- a primary joint member;
a socket connector assembly for connecting a socket to said primary joint member;
an elongated structural member having opposite ends spaced apart along, a main longitudinal axis;
a connector assembly for connecting a terminal portion to on end of said structural member;
a pivot assembly for operatively connecting the structural member to the primary joint member to permit relative rotation between said primary joint member and said structural member about an first axis defined by said pivot assembly;
a linear actuator connected at one end to said structural member and at the opposite end to said primary joint member at a location spaced from said pivot assembly, whereby extension or retraction of said actuator induces a corresponding rotation of said primary joint member relative to said structural member about said pivotal axis.

Abstract
The actuated leg prosthesis comprises a knee member, a socket connector provided over the knee member, an elongated trans-tibial member having a bottom end under which is connected an artificial foot, and a linear actuator. A first pivot assembly allows to operatively connect the trans-tibial member to the knee member. A second pivot assembly allows to operatively connect an upper end of the actuator to the knee member. A third pivot assembly allows to operatively connect a bottom end of the actuator to the bottom end of the trans-tibial member. The prosthesis can be provided as either a front actuator configuration or a rear actuator configuration.

26. An actuated leg prosthesis for above-knee amputees, the prosthesis comprising:
-
a knee member;
a socket connected to the knee member;
an elongated trans-tibial member having an upper end and a bottom end, the trans-tibial member defining a main longitudinal axis;
an artificial foot connected under the bottom end of the trans-tibial member, the artificial foot defining a front side and a rear side of the prosthesis;
a linear actuator having an upper end and a bottom end;
a first pivot assembly to operatively connect the trans-tibial member to the knee member, the first pivot assembly defining a first pivot axis that is perpendicular to the main longitudinal axis;
a second pivot assembly to operatively connect the upper end of the actuator to the knee member, the second pivot assembly defining a second pivot axis that is substantially parallel to the first pivot axis, the second pivot axis being spaced apart from the first pivot axis and the main longitudinal axis; and
a third pivot assembly to operatively connect the bottom end of the actuator to the bottom end of the trans-tibial member, the third pivot assembly defining a third pivot axis that is substantially parallel to and spaced apart from the first pivot axis. - View Dependent Claims (27, 28, 29, 30, 31, 32, 33, 34)
