Embodiment Construction

[0034] figure 1 An orthopedic joint device in the form of a prosthetic knee joint is shown, with an upper part 2 on which a thigh sleeve 20 is arranged for receiving a thigh stump. The lower part 3 is articulated distally relative to the upper part 2 so that the upper part 2 can pivot relative to the lower part 3 . On the rear side of the upper part 2 a bracket 21 is formed, on which a damping device 50 in the form of a hydraulic or pneumatic damper is arranged on the one hand and an energy store 54 in the form of an elastic tendon on the other hand. The elastic tendon is connected via a variable speed transmission 11 to an actuator 10 in the form of an electric motor. The electric motor is arranged in a shank tube which is fastened to the lower part 3 . The energy accumulator 5 in the form of an elastic tendon is fastened to the variable speed transmission 11 and the bracket 12, the electric motor 10 is activated, which acts on the bracket 12 via the variable speed transmis...

Abstract

The invention relates to a method for controlling an orthopedic joint device (1) of a lower extremity comprising an upper part (2) and a lower part (3) mounted in articulated fashion thereon, with a conversion device (5) being arranged between said upper and lower parts, via which conversion device (5), during pivoting of the upper part (2) relative to the lower part (3), mechanical work from the relative movement is converted and is stored in at least one energy store (54) and supplied back to the joint device (1) with a time offset in order to assist the relative movement, wherein the stored energy is converted back and the supply of mechanical work takes place in a controlled manner during the assistance of the relative movement.

Description

technical field [0001] The invention relates to a method for controlling an orthopedic articulation device of the lower limbs, which has an upper part and a lower part articulated on the upper part, between which a switching device is arranged, by means of which During the pivoting of the upper part relative to the lower part, the conversion device converts the mechanical work from this relative movement and stores it in at least one energy store and reintroduces it to the joint device with a time offset in order to support the relative movement . The invention also relates to an orthopedic technical joint device for the lower limbs, with an upper part and a lower part articulated on the upper part, between which a switching device is arranged, by means of which switching device the upper part During the pivoting of the lower part, the mechanical work resulting from this relative movement is converted, stored in at least one energy store and reintroduced to the joint device w...
