PROBLEM TO BE SOLVED: To provide a device for locking and moving a leg during medical treatment.SOLUTION: The invention relates to a device for the self-locking bidirectional drive of a medical treatment device with a first locking unit for blocking the rotation of an inner part 72 in a first direction of rotation R1 and for releasing the rotation of the inner part 72 in a second direction of rotation R2 and comprising a second locking unit for blocking the rotation of the inner part in a second direction of rotation and for releasing the rotation of the inner part in a first direction of rotation. The inner part is connected to the medical treatment device via a driven shaft. Two release elements 122a-122c, 123a-123c are provided which are movable by means of a drive element into one release position each, which release elements prevent the blocking of the rotation of the inner part in both directions of rotation so that a rotation of the inner part and of the medical treatment device connected to the inner part via the driven shaft is only possible by means of the drive element. |
