1. A device for the self-locking bidirectional drive of a medical treatment device, comprising
an inner part rotatable about an axis of rotation (Z), a rotationally-fixed outer part having a circular opening which surrounds the inner part and is arranged concentrically about the axis of rotation (Z), a driven shaft rotatable about the axis of rotation (Z), which driven shaft is connected to the inner part and is connectable to the treatment device, a drive element for rotating the inner part together with the driven shaft about the axis of rotation (Z), with a first clamping part and with a second clamping part which are arranged in an intermediate space between the inner part and the outer part, wherein the outer part, the inner part and the first clamping part form a first locking unit for blocking the rotation of the inner part in a first direction of rotation (R1) and for releasing the rotation of the inner part in a second direction of rotation (R2), that the outer part, the inner part and the second clamping part form a second locking unit for blocking the rotation of the inner part in the second direction of rotation (R2) and for releasing the rotation of the inner part in the first direction of rotation (R1), that a first release element movable into a first release position by the drive element is provided, which release element prevents the blocking of the rotation of the inner part in the first direction of rotation (R1) by the first locking unit, and that a second release element movable into a second release position by the drive element is provided, which release element prevents the blocking of the rotation of the inner part in the second direction of rotation (R2) by the second locking unit. |
