Modular and lightweight myoelectric prosthesis components and related methods
First Claim
1. An elbow for a prosthetic limb, the elbow comprising:
- an exterior-rotor motor;
a transmission comprising a planetary gear transmission, a non-backdrivable clutch, and a screw;
the screw adapted to receive a rotational force in a first direction from the clutch, and in response to the rotational force in the first direction, rotate in the first direction so as to cause the elbow to flex.

Abstract
Prosthetic devices and, more particularly, modular myoelectric prosthesis components and related methods, are described. In one embodiment, a hand for a prosthetic limb may comprise a rotor-motor; a transmission, comprising a differential roller screw; a linkage coupled to the transmission; and at least one finger coupled to the linkage. In one embodiment, a component part of a wrist of a prosthetic limb may comprise an exterior-rotor motor, a planetary gear transmission, a clutch, and a cycloid transmission. In one embodiment, an elbow for a prosthetic limb may comprise an exterior-rotor motor, and a transmission comprising a planetary gear transmission, a non-backdrivable clutch, and a screw.

10. An elbow component for a prosthetic limb, comprising:
-
a first limb portion and a second limb portion coupled together at an elbow joint; a transmission comprising a housing and a screw, wherein a first end of the screw is coupled to the first limb portion at a bracket; and
,the transmission housing is coupled to the second limb portion at a transmission joint positioned at a midpoint position of the transmission housing; wherein the screw and the elbow joint are adapted so that; when the screw rotates in a first direction, the screw applies a force on the bracket that causes the first limb portion to rotate about the elbow joint towards the second limb portion; and when the screw rotates in a second direction opposite to the first direction, the screw applies a force on the bracket that causes the first limb portion to rotate about the elbow joint away from the second limb portion; a bushing made of a nonlinear compliant material that encases the transmission pivot; a socket connector coupled to either the first limb portion or the second limb portion; and a frame that surrounds the transmission and is adapted to receive a battery;
wherein the screw is a differential roller screw. - View Dependent Claims (11, 12, 13, 14, 15, 16)
