Claim 0:
1. An electrosurgical colpotomy system, comprising:
an energy source;
an electrosurgical instrument having a shaft assembly including an end effector supported on a distal end portion of the shaft assembly, the end effector in electrical communication with the energy source, the end effector including a first jaw member and a second jaw member supporting a first treatment surface and movable relative to the first jaw member between an open position and a closed position, the first jaw member having a proximal end and a distal end, the first jaw member defining a first blade slot that extends through the distal end of the first jaw member, and the second jaw member having a proximal end and a distal end, the second jaw member defining a second blade slot that extends through the distal end of the second jaw member, wherein the first and second blade slots align with another to define an annular blade slot through the end effector when the first and second jaw members are disposed in the closed position; and
a uterine manipulator defining a longitudinal axis and having a head including a second treatment surface, the second treatment surface electrically coupled to the energy source and configured to transmit electrical energy to the first treatment surface when the first and second jaw members are positioned about the head of the uterine manipulator, the head supporting a knife assembly having a knife that is configured to rotate through the distal ends of the first and second jaw members as the knife moves about the longitudinal axis and through the annular blade slot of the end effector.
