Abstract
A uterine manipulator including an elongate shaft having a distal portion configured to be inserted into a uterus through a lumen of a cervix, and a return electrode coupled to the elongate shaft. The return electrode is configured to be electrically coupled to an electrosurgical generator.
Claims19
A method of determining an in-situ position of a vaginally-insertable uterine device, the method comprising:
- using an electrosurgical generator, issuing a drive signal to a first return electrode, wherein the uterine device comprises a colpotomy cup comprising an outer wall portion, a base, and a protrusion configured for receiving an elongate shaft and the first return electrode is arranged on the protrusion;
- using the electrosurgical generator, receiving a portion of the issued drive signal from a second return electrode arranged on the protrusion;
- using a processor of the electrosurgical generator, monitoring an electrical property between the first and second return electrodes based on the issued drive signal and the received portion of the issued drive signal to determine if a threshold has been traversed;
- and
- based at least in part on the threshold being traversed, using a processor to permit issuance of a second signal to an active electrode.

A method of determining an in-situ position of a vaginally-insertable uterine device, the method comprising:
- inserting the uterine device into the vagina of a patient;
- advancing the uterine device to the cervix and arranging a first return electrode of the uterine device and a second return electrode of the uterine device within the cervix;
- using an electrosurgical generator, issuing a first signal to the first return electrode;
- using the electrosurgical generator, receiving a portion of the issued first signal from the second return electrode;
- using a processor of the electrosurgical generator, monitoring an electrical property of the first and second return electrodes based on the issued first signal and the received portion of the issued first signal to determine if a threshold has been traversed to confirm that the first and second return electrodes are in contact with an inner surface of the cervix;
- and
- based at least in part on the threshold being traversed, using a processor to permit issuance of a second signal to an active electrode.
