PROSTHESIS FOR FEMORAL AMPUTEE
20200163780 · 2020-05-28 ·

Hinged connecting device (2) for a prosthesis (1) for a femoral amputee, connecting the femoral part (101) and the tibial part (102) of same in a hinged manner, and moreover comprising a damping mechanism (20) intended to counter a predetermined resistance at least during bending of the prosthesis (1), by replacing the muscle groups usually used for this purpose. The damping mechanism (200) is capable of being switched between a first operating mode (M1), selected by default, in which the value of the resistance corresponds to a first maximum value (Vmax), and a second operating mode (M2), that can be actuated only in a hyperextension position (P0) of the prosthesis (1), in which the resistance value corresponds to a second minimum value (Vmin); and the hinged connecting device (2) moreover comprises a fully mechanical locking system (3), arranged in order to allow the second operating mode (M2) to be activated only when the inclination of the tibial part (102) exceeds a first predetermined oriented angle (X1) relative to the vertical.

JOINT DEVICE

A joint device of an orthosis or prosthesis or for an orthosis or prosthesis with an upper part, a lower part, a joint that comprises a joint axis, about which the upper part is mounted such that it can be swivelled relative to the lower part, and an actuator, which is designed to influence a swivelling of the upper part relative to the lower part. The actuator is mounted at an upper part fixing point on the upper part and at a lower part fixing point on the lower part. At least two joints are arranged between the upper part fixing point and the lower part fixing point, wherein the joints enable a swivelling of the actuator relative to the upper part fixing point and the lower part fixing point, and the joint each form at least one joint axis, at least one of which is not oriented parallel to the joint axis.

Jointless prosthetic foot

A jointless prosthetic foot having a leaf spring which has a distal footfall section, a connecting section and a proximal attachment section which extends in an anterior-posterior direction and to which an attachment adapter can be fixed. The attachment adapter is mounted such as to be movable along a convexly curved path in the anterior-posterior direction.

Transfemoral rotator using push button spring clips

A transfemoral rotator is provided. The transfemoral rotator includes an inner cylinder that nests within a cavity of a base shell. The inner cylinder includes a lower cylindrical hub configured to protrude through an opening in the base shell. A spring clip mechanism operated by a push button serves to lock and unlock the transfemoral rotator to permit for rotation of a lower limb prosthesis and allow for a wearer to sit cross-legged.

A FLEXIBLE MULTI USE POST OPERATIVE PROSTHETIC SOCKET SYSTEM
20200121480 · 2020-04-23 ·

A prosthetic apparatus and system for a trans-tibial amputee consisting of a post-operative interface socket that can be adjusted to accommodate the size of an amputated limb and changes in size of the limb. The prosthetic apparatus includes a lower socket into which the post-operative socket can be inserted, the lower socket being adjustable for changes in size of the post-operative interface socket. The post-operative socket also has a removable upper back shell that immobilizes movement of the knee during an initial recovery phase but can be removed to allow the knee of the amputee to flex.

Dual purpose prosthetic foot system and method of use
10603189 · 2020-03-31 ·

A dual purpose prosthetic foot system enables a person to use the same prosthetic to either walk or swim. The foot part is joined at the ankle and can be locking in either a walking position or a swimming position. The foot allows common swimming equipment such as flippers to be attached.

CONTROLLING TORQUE IN A PROSTHESIS OR ORTHOSIS BASED ON A DEFLECTION OF SERIES ELASTIC ELEMENT

In some embodiments of a prosthetic or orthotic ankle/foot, a prediction is made of what the walking speed will be during an upcoming step. When the predicted walking speed is slow, the characteristics of the apparatus are then modified so that less net-work that is performed during that step (as compared to when the predicted walking speed is fast). This may be implemented using one sensor from which the walking speed can be predicted, and a second sensor from which ankle torque can be determined. A controller receives inputs from those sensors, and controls a motor's torque so that the torque for slow walking speeds is lower than the torque for fast walking speeds. This reduces the work performed by the actuator over a gait cycle and the peak actuator power delivered during the gait cycle. In some embodiments, a series elastic element is connected in series with a motor that can drive the ankle, and at least one sensor is provided with an output from which a deflection of the series elastic element can be determined. A controller determines a desired torque based on the output, and controls the motor's torque based on the determined desired torque.
