The present disclosure provides a mounting structure for a general prosthetic finger of a prosthetic hand. The mounting structure comprises a prosthetic hand base plate, a finger base plate connecting screw, a finger connector, a tension nut, a finger connecting screw and a finger mounting rack of the general prosthetic finger; and an axis of the finger connecting screw is perpendicular to a pointing direction of the general prosthetic finger when the general prosthetic finger is in an unbent state. The finger connector, the step-shaped tension nut, the finger connecting screw and a finger base plate connecting screw are adopted by the mounting structure to connect the general prosthetic finger with the prosthetic hand base plate, and the axis of the finger connecting screw is perpendicular to the pointing direction of the general prosthetic finger, so that the connection is reliable and the mounting structure is not easy to loosen.

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 prosthetic system includes a prosthetic valve having a valve body with a shaft defining a flow channel fluidly connectable to an interior of a socket. One or more ports in the valve body are in fluid communication with the flow channel and a membrane is positioned in the valve body. A release button associated with the membrane controls allow air flow into the socket via the one or more ports while air can flow out of the socket via the one or more ports independent of operation of the release button. A one-way valve is connected to the valve assembly that selectively permit air flow out of the socket. A valve insert is mountable on the socket and arranged to couple the valve body to the socket. The valve insert defines an opening configured to allow the shaft to extend through the valve insert and into the socket.

A cam system for an assistive device and related methods are disclosed. The cam system may comprise a cam profile and a cam follower. The cam profile has a curved outer edge comprising a concave portion. The cam follower is positioned within the concave portion when the assistive device is in an equilibrium position. The assistive device may further comprise a spring that deflects in response to a force applied by the cam system. The assistive device may have a sliding element to adjust the stiffness of the spring in deflection. The assistive device may take the form of a prosthesis or an orthosis.

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 prosthetic foot including a foot member and a heel member attached to a bottom surface of the foot member. A pump mechanism is located above the foot member and includes a housing and an elastomeric member at least in part defining a fluid chamber. The elastomeric member is operatively connected to the foot member such that when no weight is placed on the prosthetic foot the volume of the fluid chamber is zero or near-zero and upon heel strike the housing rotates relative to the foot member to expand the volume of the fluid chamber and draw fluid into the fluid chamber from a prosthetic socket in fluid communication with the pump mechanism.

A prosthetic device includes a first place including a first end portion arranged for attachment to a foot member of a prosthetic foot. A second end portion is arranged to extend freely over at least a portion of the top surface of the foot member. A second plate includes a first end extending over a heel member of the prosthetic foot and a second end extending over and attached to the second end portion of the first plate. The second end portion of the first plate situated between the foot member and the second plate. A pump mechanism includes a housing secured to the second plate and a membrane operatively connected to the first place and the housing. The pump mechanism defines a fluid chamber between a bottom surface of the housing and a top surface of the membrane.

A low profile prosthetic foot comprises a foot member extending at an incline from an anterior portion to a posterior portion thereof and configured to flex during motion, and an adapter mounted solely at a posterior section thereof to the posterior portion of the foot member so that the adapter's anterior section can move relative to the foot member and roll-up onto the foot member during motion.
