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).
Claims12
An orthopedic knee joint, with an upper part (2) on which upper connecting means (20) are arranged, with a lower part (3) which is mounted pivotably on the upper part (2) and has connecting means for orthopedic components (4), and with a stop (7) for limiting an extension movement, characterized in that the stop (7) is designed to be movable and is coupled to an adjusting device (64), which is coupled to a control device (6) that actuates the adjusting device (64) as a function of sensor data and changes the position of the stop (7).
The orthopedic knee joint as claimed in one of the preceding claims, characterized in that the sensor data are determined via sensors (8, 9) designed as flexion angle sensor, acceleration sensor, inclination sensor and/or force sensor.
The orthopedic knee joint as claimed in one of the preceding claims, characterized in that the stop (7) is coupled to the adjusting device (64) via a thread (72).
A method for controlling an orthopedic knee joint with an extension stop and with an adjusting device by which the position of the extension stop can be changed, characterized in that the position of the extension stop is changed as a function of sensor data.
