US Patent 9011433 Bipolar colpotomy device

A bipolar electrosurgical assembly is for use in female pelvic surgical procedures. A first shaft includes a uterine manipulator, a second shaft that fits over the first shaft includes a colpotomy cup and first and second electrodes, and a third shaft can be provided over the second shaft and carries a seal for maintaining pneumoperitoneum. The colpotomy cup uses the first and second electrodes for resecting uterine tissue. Incision and resection may be performed by positioning the colpotomy cup near the cervico-vaginal junction, activating the first electrode, and moving one or both of the electrodes.
