| 摘要 |
The invention relates to a torsion device of an exoprosthesis system, with a proximal part (1) which, counter to the action of a resilient torsion element, can be turned in positive and negative directions of rotation (5, 6) in relation to a distal part (2). To increase the functional range, it is proposed that the torsion element (4), in the positive direction of rotation (5), has a torsion characteristic different than that in the negative direction of rotation (6).
