Embodiment Construction

[0026] figure 1 The basic structure of an orthopedic knee joint in the form of a thigh prosthesis 1 with an upper part 2 and a lower part 3 on which a prosthetic foot 4 is fastened is shown. The upper part 2 and the lower part 3 are pivotably connected to one another about a pivot axis 5 . An upper connection device 20 in the form of a prosthesis cartridge is arranged at the proximal end of the upper part 2 . When designing the orthopedic knee joint as a prosthesis, the connecting device is designed in the form of a cylinder which partially surrounds the thigh or in the form of a strap or other fastening means. The upper part 2 and the lower part 3 are then guided on the inside or on the outside by the natural leg, the orthopedic part 4 is then the foot shell into which the natural foot is inserted.

[0027] Arranged between the upper part 2 and the lower part 3 is a control unit 6 which has an upper fastening point 21 and a lower fastening point 31 . The upper fastening po...

Abstract

The invention relates to an orthopedic knee joint, comprising an upper part (2), on which upper connecting means (20) are disposed, a lower part (3) pivotally supported on the upper part (2), connecting means for orthopedic components (4), and a stop () for delimiting an extension movement, wherein the stop (7) is configured displaceably and coupled to an adjusting device (64), which is coupled to a control device (6), which actuates the adjusting device (64) as a function of sensor data and changes the position of the stop (7).

Description

technical field [0001] The invention relates to an orthopedic knee joint comprising an upper part on which an upper connecting device is arranged and a lower part mounted pivotably on the upper part and having a connection means for orthopedic components; and stops for limiting extension movement. The invention also relates to a method for controlling an orthopedic knee joint. Background technique [0002] The aim of prosthetic care is basically to provide the best possible replacement for a lost limb without functional limitations. If a femoral prosthesis with a prosthetic knee joint has to be provided on a patient, there are a number of structural possibilities for constructing such a prosthetic knee joint. [0003] A simple passive monocentric prosthetic knee joint is particularly simple in terms of structure and production, but only incompletely simulates a natural knee joint and in particular does not allow a natural walking gait. The protection against bending of th...
