A uterine manipulator comprising:
- an elongate shaft including a distal portion configured to be inserted into a uterus through a lumen of a cervix;
- and
- a colpotomy cup coupled to the elongate shaft and comprising an outer wall portion, a base portion, and a protrusion extending distally away from the base portion,
- wherein:
- the protrusion is configured to be inserted into the lumen of the cervix;
- the protrusion includes a return electrode that is configured to be electrically connected to an electrosurgical generator, to receive an electrical signal from an active electrode via the cervix, and to return the electrical signal to the electrosurgical generator;
- and
- the elongate shaft is configured to pass through the protrusion.
