摘要:
The invention relates to a method for controlling a damping change in an artificial knee joint of an orthosis or prosthesis, wherein the artificial knee joint has an upper part (1), a lower part (2) mounted thereon such that it can pivot about a pivot axis (4), and a resistance unit (6) which is secured on the upper part (1) on an upper articulation point (61) and on the lower part (2) on a lower articulation point (62) in order to provide a resistance to a bending or extending of the artificial knee joint, wherein an adjusting device (7) is assigned to the resistance unit (6) for changing the flexion resistance, wherein the resistance (R) of the resistance unit (6) is increased by an increasing knee angle (a) starting from a knee angle threshold value.

The invention relates to a seat unit (25) for a wearable sitting posture assisting device (10) comprising at least one sitting means (26) designed to form an adjustable and/or self-adjusting seat surface (28) to be used in at least one at least partly sitting posture and in a walking mode, and comprising a frame means (27) designed to receive a weight force of a person (11) sitting on the sitting means (26) that is mounted on the frame means (27), and to a wearable sitting posture assisting device (10) with such a seat unit (25).
摘要:
A dynamic tension system connects to an orthopedic device having a frame and a hinge connected to the frame. The dynamic tension system includes a cable, an adjustment mechanism connected to the cable and arranged to incrementally wind or release the cable, and a tension control device connected to the adjustment mechanism and arranged to limit the adjustment mechanism from winding of the cable past a predetermined tension level.

Disclosed is a therapeutic stretching apparatus, which in particular provides a user with a system for providing an assist to increase knee extension as well as for maintaining stability of the knee after surgery. This device can not only act as a therapeutic stretching apparatus but also can act as a primary post-op knee brace with locks/limits on hinge to prevent user from further injuring the joint.
摘要:
An orthopedic brace for a body joint has a first longitudinal support, a second longitudinal support and a hinge joint rotatably connecting the longitudinal supports, thereby rendering them positionable at different hinge joint angles. The brace also has a tensioner attached at its opposite ends to the first and second longitudinal supports which intermediately engages a cam positioned at the hinge joint. The tensioner applies a variable elastic tensioning force to the longitudinal supports which varies as a function of the hinge joint angle and biases the longitudinal supports toward a position corresponding to a desired hinge joint angle.
