摘要:
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.

The invention relates to a prosthetic device (10, 20, 31) comprising a shell assembly for receiving an amputation stump and a frame unit (13) for connecting the shell assembly to a prosthesis (16). According to the invention, the shell assembly comprises at least two shell sections (11, 12; 21, 22; 32), which lie opposite one another, enclose a receiving area and are interconnected by means of the frame unit. The relative positions of said sections can be modified. The shell assembly is provided at least partially with a lining (45), in which a vacuum can be produced and which contains a plurality of moulding particles (46) and with a fixing device (25, 51) for fixing the relative positions of the shell sections.
摘要:
Prosthesis set ( 1 ) for persons with amputated limbs/stumps ( 10 ) where the prosthesis set consists of an anchoring part ( 2 ) arranged internally in a remaining marrow bone ( 11 ) and an external prosthesis ( 7 ). The anchoring part ( 2 ) has a bolt-like design with a stem ( 3 ) and an expanded head ( 4 ) in one end, wherein the stem ( 3 ) can be inserted and anchored in the remaining marrow bone ( 11 ). The expanded head ( 4 ) forms a subcutaneous termination of the marrow bone ( 11 ) and a local expansion ( 12 ) at the end ( 10 ) of the amputated limb. The external prosthesis ( 7 ) has an internal design ( 8 ) adapted to the local expansion.

The present invention provides an articular endoskeletal prosthesis (1) for providing a user with at least one of a mechanically operable pivoting wrist, elbow and shoulder joint. The prosthesis (1) has at least one elongate endoskeletal tube upper limb member (5) with a proximal end portion (6) having a pivotal connection (7) to a support body (9) therefor. One of said upper limb member proximal end portion (6) and said support body (9) has a fixed worm gear wheel means (19) and the other a drive motor (22) having a drive output worm (25) extending generally tangentially of said worm gear wheel means (19) for engagement with the gear teeth of said worm gear wheel means (19) so that when said drive motor (22) is operated, in use of the prosthesis (1), said upper limb member (5) moves around said worm gear wheel means (19) so as to pivot said upper limb member about its pivotal connection (7).

摘要:
A control method for an arm prosthesis having at least one powered joint and at least one inertial measurement sensor (IMS) includes determining a motion and an orientation of the arm prosthesis relative to the inertial reference frame based at least on an output of the IMS and generating control signals for the at least one powered joint based on the motion and the orientation of the prosthetic arm.
