1. A device comprising:

  • a surgical instrument having a distal end adapted to perform a surgical procedure on a patient and a proximal end adapted to be controllable by an operator, the instrument including;

    a rotatable shaft;

    a surgical component drivable by the shaft, constructed and arranged for contact with tissue in a surgical operating field;

    a liquid jet-driven rotatable rotor, drivingly coupled to the rotatable shaft, when the instrument is in operation, such that rotation of the liquid jet-driven rotatable rotor causes a corresponding rotation of the rotatable shaft, where the liquid jet-driven rotatable rotor is maintained in a surrounding gaseous environment while being rotatably driven by at least one liquid jet during operation, so that essentially no part of the rotor is submerged in liquid.
