A vacuum suspension system includes a rigid socket defining a socket wall having exterior and interior surfaces. The socket defines an aperture extending between the exterior and interior surfaces, and has a closed distal end and an open proximal end with an interior cavity defined by the interior surface. A fluid regulator is provided at the aperture and operatively engages the fluid regulator. A pump system includes a pump and a covering for securing over the exterior surface of the socket and carrying the pump. The pump is configured for placement proximate to the fluid regulator and arranged for drawing air from the socket through the aperture. A chamber having a variable volume is formed by a space defined between the exterior surface and an inner surface of the covering proximate to the pump.

The invention relates to an orthopaedic device for the orthotic or prosthetic provision of a patient with • a knee joint (10), which has a proximal upper part (11) and a distal lower part (13) arranged pivotably thereon, • an ankle joint (20), • a pivoted foot part (23) which can be fastened distally to the ankle joint (20), and • a shin part (14) arranged between the ankle joint (20) and the knee joint (10), wherein the upper part (11) of the knee joint (10) or a thigh part fastened thereto that can be attached to the patient's body is coupled with the foot part (23) by means of a force transfer device (3; 30, 31, 32, 35; 40, 41, 42), which causes a plantar flexion of the foot part (23) when a knee is flexed.

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 prosthetic includes a pair of prosthetic members movably coupled together to allow movement of the pair of prosthetic members with respect to one another. A hydraulic actuator or damper including hydraulic fluid in a hydraulic chamber is coupled to one of the pair of prosthetic members. A hydraulic piston is movably disposed in the hydraulic chamber and coupled to another of the pair of prosthetic members. A hydraulic flow channel is fluidly coupled between opposite sides of the chamber to allow hydraulic fluid to move between the opposite sides of the chamber as the hydraulic piston moves therein. A voice coil valve is coupled to the hydraulic flow channel to vary resistance to flow of hydraulic fluid through the flow channel, and thus movement of the piston in the chamber, and thus influencing a rate of movement of the pair of prosthetic members with respect to one another.

A range of motion (ROM) prosthetic foot and passive dampening ankle joint have limited dorsiflexion-plantarflexion (up and down) pivoting to accommodate different environments, and a spring to provide resilient resistance to plantarflexion (or lowering of the toe), and to bias the foot in dorsiflexion (or raising the toe). The ankle joint has a rear pivot rearward of a hydraulic link for a smooth feel. The ankle joint has an internal bumper in a hydraulic cylinder for a smooth feel. The ankle joint has an internal hydraulic compensator disposed in the cylinder and carried by the piston to equalize volume.

An ankle module for a prosthetic foot can have an adapter portion pivotally coupled to a base portion. The base portion can be coupled to the prosthetic foot. The adapter portion can have a coupling member that removably couples the prosthetic foot to a prosthetic pylon or socket. The adapter portion can also have cylinders housing pistons slidably displaceable within the cylinders. An actuator is selectively actuatable to place the cylinders in fluid communication, allowing a fluid to flow between the cylinders as an angular position of the adapter portion is adjusted relative to the base portion, thereby adjusting the dorsi-plantar position between the adapter portion and the base portion of the ankle module. The actuator can be selectively actuatable to fluidly isolate the cylinders from each other so that the angular position of the adapter portion relative to the base portion remains substantially fixed.

Die Erfindung betrifft ein orthopädisches Fußteil mit einem Unterschenkel-Anschlussteil, einem als Knöchelgelenk (7) wirkenden Drehgelenk (5), mit dem ein Fußteil (10) in Richtung Dorsalflexion und Plantarflexion drehbar mit dem Anschlussteil verbunden ist, mit einer die Drehbewegung um das Drehgelenk (5) beeinflussenden Dämpfungsanordnung (17), mit einer Sensoranordnung zur Erkennung von Aktionszuständen des orthopädischen Fußteils und mit einer mit der Sensoranordnung verbundenen Steuerung, die die Dämpfungsanordnung (17) steuert. Die Aufgabe wird dadurch gelöst, dass die Sensoranordnung einen den Winkel zwischen Anschlussteil und Fußteil (10) messenden Knöchelwinkelsensor, einen auf die Lotrechte bezogenen Absolutwinkelsensor (20) und einen Momentensensor (21) zur Feststellung des Drehmoments am Knöchelgelenk (7) oder einer ein Drehmoment am Knöchelgelenk (7) auslösenden Kraft aufweist.

The invention relates to a joint mechanism of a knee orthosis or knee prosthesis, having a first part (14), a second part (15), which is pivotable relative to the latter, and attachment means (2) for securing the joint mechanism (1) to a user of the knee orthosis or knee prosthesis, and having a locking mechanism (4, 40) with which a pivoting of the two parts (14, 15) relative to each other in a flexion direction is prevented by a form-fit element (4) which is arranged movably on the second part (15) and which, in the locking state, engages with a form fit in a recess (40) assigned to the first part (14), wherein the form-fit element (4) is mounted rotatably on the second part (15) and has a contour which, in the locked position, protrudes into the recess (40) and, in the released position, allows the first part (14) to pivot past the bearing of the form-fit element (4).
