A hydraulic actuator for orthotics or prosthetics, comprising a control element with a housing, in which a cylinder is arranged, in which a piston is mounted so as to be movable and divides the cylinder into a flexion chamber and an extension chamber, a fluidic connection is arranged between the flexion chamber and the extension chamber, and in each of said chambers there is arranged a control valve for influencing the extension movement or flexion movement, a motorised pump being arranged in the fluidic connection, with the hydraulic fluid being conducted from one chamber to the pump through at least one control valve in an intake-side connection line, and a check valve being arranged in a delivery-side connection line from the pump to the other chamber and blocking a return flow of the pumped medium from this chamber to the pump against the conveying direction of the pump.

The invention relates to an orthopedic joint with a first component, a second component that is arranged on the first component such that it can be swiveled about a swivel axis, and at least one damper that is configured and arranged to damp a swiveling of the first component relative to the second component, and an actuator for swiveling the first component relative to the second component in at least one direction. According to the invention, the actuator is arranged on the first component or the second component on a medial or lateral side such that it can be detached.

The invention relates to a cover for a prosthetic hand, having a textile main part that covers at least a palm area of a prosthetic hand when worn. The main part is designed as a partial glove having through-openings for prosthetic fingers and at least one distal finger cap consisting of a non-textile plastic material replaces a missing textile finger area.

The invention relates to a sensor device comprising at least two sensors ( 12 ) and a main body ( 18 ) with an upper part ( 2 ) and a lower part ( 4 ) and at least one elastic element ( 6 ) arranged between the upper part ( 2 ) and the lower part ( 4 ), wherein the upper part ( 2 ) can be displaced relative to the lower part ( 4 ) from a zero position along a preferred direction and tilted about a tilt axis perpendicular to the preferred direction, wherein at least one elastic element ( 6 ) is deformed and the at least two sensors ( 12 ) are each configured to determine a distance between the upper part ( 2 ) and the lower part ( 4 ), so that a displacement and/or tilt of the upper part ( 2 ) relative to the lower part ( 4 ) from the zero position can be determined.

The invention relates to a method for controlling a lower leg prosthesis comprising a foot element, a lower leg element pivotably arranged thereon and an adjustable resistance device for applying a resistance against a swivelling of the foot element relative to the lower leg element, wherein a first switching angle is defined as a predetermined ankle angle value between the lower leg element and the foot element, a second switching angle is defined as a predetermined lower leg angle value of the absolute angle of the lower leg, the method comprising the steps: at least also on the basis of a height difference between the position of the foot element in a step cycle and the position of the foot element in the previous step cycle, determining whether the wearer of the lower leg prosthesis is walking downhill, and increasing the resistance of the resistance device to a predetermined resistance value when a block criterion is met, wherein the block criterion is met if it has been determined that the wearer is not walking downhill and the second switching angle is reached, or if it has been determined that the wearer is walking downhill and the switching angle reached later in the step cycle is reached.

A prosthetic system with a prosthesis, which has two prosthetic parts that are pivotally connected together about a joint axis via a prosthetic joint with a joint upper part and with a joint lower part, and a cover element, which at least partly covers a gap between the two prosthetic parts or between one prosthetic part and the joint lower part. The cover element is pivotally mounted about a pivot axis on one prosthetic part, a component of a cosmetic prosthetic element, said component being secured to one prosthetic part or one joint part or the prosthetic joint and is coupled to the joint upper part of the prosthetic joint via at least one coupling element in a form- and/or force-fitting manner such that a pivotal movement of the prosthetic parts about the joint axis leads to a simultaneous pivotal movement of the cover element about the pivot axis.

A prosthetic hand with a chassis ( 20 ) and at least one base element ( 10 ) for fastening a prosthetic finger to the chassis ( 20 ), wherein a longitudinal guide for the base element ( 10 ) is arranged or formed on the chassis ( 20 ), the base element ( 10 ) being mounted in said longitudinal guide, wherein the longitudinal guide blocks two translational degrees of freedom and a clamping element ( 30 ) is assigned to the longitudinal guide, said clamping element being displaceably mounted in or on the chassis ( 20 ) or the base element ( 10 ) between a locking position and an unlocking position and effecting a blocking of the third translational degree of freedom in the locking position.

The invention relates to a method for adjusting a microprocessor-controlled orthopedic device which is worn on the body of a patient fitted with such a device and influences movement by microprocessor-controlled actuation of actuators, the method comprising the following computer-implemented steps: providing a digital communication link from a mobile terminal device to an adjustment database, in which at least one adjustment value for at least one parameter of the respective microprocessor-controlled actuation and associated patient data of a patient fitted with the respective orthopedic device are stored for a plurality of microprocessor-controlled orthopedic devices, calculating at least one adjustment value of at least one parameter of the microprocessor-controlled actuation of the orthopedic device of the patient depending on patient data from the patient whose microprocessor-controlled orthopedic device is to be adjusted, and/or the adjustment values stored in the adjustment database and associated patient data, displaying the at least one calculated adjustment value on the mobile terminal device in order to adjust the microprocessor-controlled orthopedic device.

The invention relates to a method for controlling at least one actuator ( 4 ) of an orthopedic device ( 2 ) with an electronic control device (E), which is coupled to the actuator ( 4 ) and at least one sensor ( 8 ) and which has an electronic processor (μC) for processing sensor data (s), wherein at least one state machine (SM) in which states (z) of the orthopedic device ( 2 ) and state transitions of the actuator ( 4 ) are determined is stored in the control device (E), wherein a classifier (K) in which sensor data (s) and/or states (z) are automatically classified within the scope of a classification method is stored in the control device (E), wherein the state machine (SM) and the classification method are used in combination and, on the basis of the classification and the states (z), a decision is made about the manner of activating or deactivating the actuator ( 4 ) as a control signal.

A method for configuring a myoelectrically controlled prosthetic system with a prosthesis socket and several lead electrodes for recording electric muscle activities, featuring the steps: placement of a surface electrode arrangement comprising several surface electrodes around the circumference of a residual limb, recording of electric muscle activity in muscles of the residual limb as electromyographic signals, the activity being recorded by the surface electrodes, evaluation of the myoelectric signals with regards to the distinctness of the signals, selection of the control procedure that is to be used to control the prosthesis system, based on the evaluation of the distinctness of the signals, and fixing of the lead electrodes to the prosthesis socket.
