Colpotomy systems, devices, and methods with rotational cutting
A colpotomy system includes an energy source and a uterine manipulator that is electrically coupled to the energy source. The uterine manipulator supports a colpotomy cup and extends to a conductive distal tip portion. The colpotomy cup includes a conductive surface. One or both of the conductive distal tip portion and the conductive surface of the colpotomy cup are configured to return monopolar energy to the energy source.
1. A method of conducting monopolar energy through a colpotomy system, the method comprising:
positioning a colpotomy cup of a uterine manipulator of the colpotomy system adjacent to a patient's uterus, the colpotomy cup including a non-conductive proximal portion and a distal conductive portion;
positioning a monopolar instrument of the colpotomy system adjacent to the uterine manipulator; and
transmitting monopolar energy from the monopolar instrument to a conductive distal tip portion of the uterine manipulator that is coaxial with a longitudinal axis of the colpotomy cup and/or to the distal conductive portion of the colpotomy cup to effectuate a colpotomy, the conductive distal tip portion extending distally beyond the colpotomy cup of the uterine manipulator to a distal end of the uterine manipulator.
2. The method of claim 1 , wherein transmitting monopolar energy includes returning monopolar energy from the monopolar instrument through the conductive distal tip portion of the uterine manipulator.
3. The method of claim 1 , wherein transmitting monopolar energy includes returning monopolar energy from the monopolar instrument through a conductive surface of a distal conductive portion of the colpotomy cup of the uterine manipulator.
4. The method of claim 1 , wherein transmitting monopolar energy includes returning monopolar energy to a generator.
