A prosthesis system can have an advantageous use over conventional prostheses in certain activities, including, but not limited to certain sports activities: The system includes, elastic member(s) that can store and release energy. The storing and releasing of energy in the elastic members happens during the movements made by the user and with the application of the user's own body weight while performing an activity. Implementations can also include a variety of routing configurations for the elastic member(s), as well as a variety of mounting points to integrate the elastic member(s) into the system, and/or a variety of adjustable anti-hyperextension members, and/or a variety of interchangeable shoes used for applicable activities.

A two-part prosthetic socket which includes an inner socket component having an inner profile substantially complementary to a profile of a residual limb of a patient, and an outer socket component configured to releasably attach about an outer surface of the inner socket component is disclosed. The inner profile of the inner socket component may be determined from digital data output from a medical imaging scan of the residual limb, which provides a three-dimensional digital profile of the residual limb that includes information on the size and location of at least bone and bone spurs, muscle, scar tissue, and neuroma. The digital data may further include a designed operating range for the size and shape of the three-dimensional digital profile of the residual limb based on such information. The two-part prosthetic socket may be manufactured using additive manufacturing, wherein the inner socket may be formed of a flexible material and the outer socket may be formed of a rigid material.

The present invention relates to a an attachment device for attaching a prosthesis to a bone, comprising: a base plate having an extension in an xy-plane; a first holder for holding a first abutment; a second holder for holding a second abutment; a locking plate attached to the base plate to restrict movement of the holders in a z-direction away from the base plate. The locking plate is configured to allow rotation of the first and second holder around a z-axis perpendicular to the xy-plane. The locking plate and the base plate is configured to allow movement of the first holder along the x-direction and to prevent movement the y-direction and to prevent movement of the second holder in the x- and y-direction. At least one flexible member is arranged between each of the first and second holders and the base plate, the flexible member being flexible in the z-direction to allow movement of the first and second holder in the z-direction and to allow the first and second holder to tilt with respect to the xy-plane.

An adaptive robotic finger prosthesis according to the inventive concepts includes a proximal phalanx body configured to be worn on a proximal phalanx portion of a cut finger, a middle phalanx body connected to the proximal phalanx body and configured to function as a middle phalanx portion of the cut finger, a distal phalanx body connected to the middle phalanx body and configured to function as a distal phalanx portion of the cut finger, a first proximal phalanx link disposed under the proximal phalanx body, a second proximal phalanx link disposed on the proximal phalanx body and joint-connected to the first proximal phalanx link, and a proximal phalanx elastic member provided at a joint between the first proximal phalanx link and the second proximal phalanx link to provide elastic force.

A motion assistance apparatus including a fixing module to be attached to a waist of a user, a driving module provided in the fixing module to provide a torque to assist a motion of the user, a supporting module connected to the driving module to support a portion of a circumference of a leg of the user, and a controller configured to control the driving module to provide a torque to maintain a close contact between the supporting module and the leg of the user while the user is not walking.

A prosthesis having a prosthetic foot with a forefoot area and a heel area, a prosthetic lower leg, and a prosthetic foot adapter for arranging the prosthetic foot on the prosthetic lower leg. The prosthetic foot adapter includes an upper part for fixing it to the prosthetic lower leg such that it is torque-proof in relation to a sagittal plane, a lower part for fixing it to the prosthetic foot such that it is torque-proof in relation to a sagittal plane, and a resistance element. The upper part can be swivelled on the lower part about a swivel axis against a restoring force exerted by the restoring element, the swivel axis extending from the heel area to the forefoot area.

A prosthetic foot having a base spring having a toe end portion and a heel end portion, and a top spring assembly. The top spring assembly includes a first spring member having a distal end and a proximal end, a second spring member spaced apart from the first spring member along substantially an entire length of the first spring member, the second spring member having a distal end and a proximal end, a first bond connection provided between the distal ends of the first and second spring members, a second bond connection provided between the distal end of the second spring member and a top surface of the base spring in a forefoot portion of the base spring, and a spring connector extending through at least a first hole formed in the base spring, the second bond connection and the second spring member.

A joint assembly including a plurality of frames, each including contactors provided in opposite directions to each other and a middle portion configured to connect the contactors, and a connecting member configured to maintain a state in which contactors of two neighboring frames among the plurality of frames are in contact with each other is disclosed.

The present disclosure includes a finger exoskeleton including a plurality of joints and a plurality of sensors configured to measure rotation of at least some of the plurality of joints of the finger exoskeleton. The finger exoskeleton also includes a series elastic actuator comprising a spring element, the series elastic actuator configured to rotate at least one of the plurality of joints. The finger exoskeleton also includes a computing device configured to control operation of the series elastic actuator based on a torque of the at least one of the plurality of joints, the torque determined at least based on the spring element and rotation of the at least one of the plurality of joints. The present disclosure also includes associated methods and hand exoskeletons.

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.
