Claim 12:
13. A rotation assembly for connecting to an operating table for the purpose of rotating a patient's leg around its longitudinal axis, wherein the rotation assembly comprises:
an interface for attaching the foot of the patient's leg to the rotation assembly;
a rotor, to which the interface is connected in a torsionally resistant manner and which is operable to rotate the interface and thus the patient's leg about the longitudinal axis;
a stator, on which the rotor is rotatably mounted, such that the rotor can rotate relative to the stator;
a rotary handle for rotating the rotor; and
a locking assembly for blocking the rotation of the rotor relative to the stator,
the locking assembly comprising a plurality of locking pins and a plurality of locking recesses each shaped to receive a locking pin,
wherein the locking assembly comprises different quantities of locking pins and locking recesses;
wherein the rotary handle is mounted on the rotor so as to move the rotor;
wherein the locking assembly is actuated by means of moving the rotary handle on the rotor;
wherein the locking assembly can be unlocked for rotation by axially moving the rotary handle such that all the locking pins are simultaneously pulled out of the locking recesses; and
wherein the plurality of locking pins comprises four groups of locking pins, wherein one of the respective locking pins of the four groups of locking pins is accommodated with one section completely in one of the respective locking recesses in order to block the rotational movement of the rotor.
