1. A uterine manipulator, comprising:
a shaft including a proximal end, and a distal end;
a manipulator handle coupled to the proximal end of the shaft;
a cutting assembly rotatably disposed about the shaft, the cutting assembly including:
a tube rotatably disposed about the shaft;
a cutting handle coupled to a proximal portion of the tube;
a cup to receive at least a portion of a fornix of a patient, the cup being coupled to a distal portion of the tube; and
a retractable cutter extendable distally with respect to the cup, the retractable cutter being movable from a retracted position to an extended position, wherein the retractable cutter extends distally beyond the cup when in the extended position, wherein the cutting assembly can be rotated about the shaft by the cutting handle to allow the retractable cutter to travel in a circle at a junction of a cervix and a vagina to permit transection of a uterus and a cervix from a vagina;
an outer tubular member surrounding the tube of the cutting assembly to permit the cutting assembly to be rotated within the outer tubular member while the outer tubular member is held stationary;
a pneumooccluder disposed on the outer tubular member, the pneumooccluder including an inflatable member coupled to a filling tube;
an electrical conductor extending proximally from the retractable cutter at a location that is radially outward with respect to an exterior surface of the tube of the cutting assembly and radially inward with respect to the pneumooccluder;
a further tubular member extending along a length of the manipulator, the further tubular member being located radially outwardly with respect to an exterior surface of the tube of the cutting assembly and radially inward with respect to the pneumooccluder, wherein the electrical conductor passes through a lumen defined at least in part by the further tubular member;
a mechanical actuator mechanically coupled to the retractable cutter, the mechanical actuator being operable to mechanically advance and retract the cutter between the extended position and retracted position; and
an electrical connector to electrically couple an electrosurgical unit to the retractable cutter through the electrical conductor.
