Space-saving ratchet unit with freewheel

A ratchet of a medical device comprising:

• a torque-guiding/-input element which is arranged so as to be rotatable around/with respect to a torque-discharging/-output element and, for torque transfer, is coupled to the torque-discharging/-output element via a toothed unit or transmission which forms a freewheel with selectable sense of rotation and has a first torque transfer sleeve which is coupled to/in the torque-guiding/-input element in a non-rotatable and axially fixed manner and a second torque transfer sleeve which is coupled to/in the torque-guiding/-input element so as to be rotationally fixed with but axially movable relative to the torque-guiding/-input element, the first torque transfer sleeve comprising a first toothing and the second torque transfer sleeve comprising a second toothing that acts in an opposite direction of the first toothing, and depending on a manually adjustable axial position of the second torque transfer sleeve, the first and second toothings can be selectively but alternately brought into meshing engagement with an intermediate sleeve which is arranged so as to be axially movable relative to the first and second toothings, is preloaded toward the first and second toothings of the first and second torque transfer sleeves, and is coupled to the torque-discharging/-output element for torque transfer.
