A prosthetic foot, including a keel having a longitudinal axis. The keel includes a keel body including a heel portion, a forefoot portion, and an ankle portion positioned between the heel portion and the forefoot portion. The ankle portion includes a housing having a vertically oriented central axis. In addition, the prosthetic foot includes a coupling assembly disposed within the housing of the ankle portion. The coupling assembly includes a bearing member disposed about the central axis, a support sleeve concentrically disposed about the bearing member, and an embedding member disposed about the support sleeve. The embedding member includes a plurality of interlocking rings.

A device for fixing two orthopedic components to one another includes a receiving element arranged on a first orthopedic component, which receiving element has a receptacle and includes a connecting element arranged on a second orthopedic component. The connecting element has a connector. The connector can be inserted into the receptacle and is coupled with the receiving element in a tensile force, compressive force, and torque-transmitting manner. At least one flow- and/or data-transmitting contact is arranged on the connecting element and the receiving element so as to correspond to one another, which form an electrical and/or data-transmitting connection with one another in a fixed state of the orthopedic components.

Disclosed herein are systems and methods for determining alignment angles between a first prosthetic component and a second prosthetic component that are joinable together in a fixed orientation relative to each other, wherein the fixed orientation includes a first angle and optionally also a second angle that are perpendicular to each other, and wherein the first and/or second angles are selectable from a range of angles to provide a desired fixed orientation between the two prosthetic components. The system includes a magnet fixedly coupled to the first prosthetic component and one or more magnetic intensity sensors configured to be coupled to the second prosthetic component in a fixed orientation relative to the second prosthetic component such that the sensors are operable to sense a magnetic field of the magnet and produce an output signal in response to the strength of the sensed magnetic field. The system can include a processor operable to receive the output signals from the sensors and determine the first and/or second angles.

A gripping device having a chassis, at least one first finger element pivotally mounted on the chassis, at least one drive, and a force transmission element coupling the drive to the first finger element. The force transmission element pivots the first finger element relative to the chassis about two differently oriented pivot axes.

A prosthesis foot is provided with a structural component with proximal connecting device for fixing the prosthesis foot to a lower leg tube, lower leg shaft or a prosthesis knee joint, wherein the proximal connecting device is designed as a joint or comprises as at least one joint.

A prosthetic appendage for attachment to an outer extremity of an amputated limb that is composed of modular elements fabricated by three-dimensional printing. In one embodiment the prosthetic appendage is a leg. The prosthetic leg includes a foot portion and a plurality of modular and three-dimensionally printed limb elements. One of the plurality of limb elements is pivotally coupled to the foot portion and another of the limb elements is configured at one end to receive the outer extremity of the amputated leg. In another embodiment of the present invention the prosthetic appendage is a hand. The prosthetic hand includes a wrist element with one end configured to receive the outer extremity of an amputated hand, a base portion attached to the wrist element and a plurality of modular and three-dimensionally printed finger elements selectively coupled to adjacent finger elements or the base to form prosthetic fingers.

A knee adapter for connecting an endoprosthesis to an exoprosthesis includes a ball joint. The ball joint comprises a partially spherical joint head and a joint socket shaped to be complementary to the joint head. The joint head is mounted in the joint socket and is configured to be arranged at one of the endoprosthesis and the exoprosthesis. The joint socket is configured to be arranged at the other of the endoprosthesis and the exoprosthesis. The joint head is affixed in the joint socket by at least one shear element.

The keel includes a keel body including a heel portion, a forefoot portion, and an ankle portion positioned between the heel portion and the forefoot portion. The ankle portion includes a housing having a vertically oriented central axis. In addition, the prosthetic foot includes a coupling assembly disposed within the housing of the ankle portion. The coupling assembly includes a bearing member disposed about the central axis, a support sleeve concentrically disposed about the bearing member, and an embedding member disposed about the support sleeve. The embedding member includes a plurality of interlocking rings.

A prosthetic hand system may include a plurality of prosthetic fingers and a prosthetic thumb. The prosthetic hand system may include a thumb drive mechanism that may be used to actuate the prosthetic thumb. In some examples, the thumb drive mechanism may be configured to enable the prosthetic thumb to perform a pinching or grasping motion and a release motion. The prosthetic hand system may also include a backlock that enables the prosthetic thumb to maintain pinching or gripping pressure after a motor has been disengaged. The prosthetic hand system may also include a gear lock that may be configured to lock a finger joint. The prosthetic hand system may also include an adaptive gripping joint that may be located on each prosthetic finger. In some examples, the adaptive gripping joint may be configured to passively adapt the plurality of prosthetic fingers to one or more differently shaped objects.
