A bipolar electrosurgical colpotomy device includes a colpotomy cup and a tissue containment bag. The colpotomy cup includes a first electrode located adjacent to a rim of the cup, the rim being configured to contact an internal surface of a patients cervico-vaginal junction. The tissue containment bag includes an opening and a second electrode located adjacent to the opening. The tissue containment bag is configured to surround the patients uterus and the opening is configured to fit over an external surface of the patients cervico-vaginal junction. Applying a voltage potential between the first and second electrodes vaporizes tissue at the patients cervico-vaginal junction by electrosurgical energy passing through the tissue disposed between the first and second electrodes. The tissue containment bag then can be used to remove the uterus from the patient, possibly after masticating the uterus within the bag.
