ABSTRACT:
A laparoscopic surgical ligation and electrosurgical coagulation device has an elongated handle sized to be received in a trochar and having a central passageway extending therethrough. A first channel is provided in the handle along one side of the passageway and is generally parallel thereto. A second channel is provided in the handle which is generally parallel to the passageway and spaced from the first channel. A suture extends through the central channel passageway and has a loop with a slip knot on the distal end thereof and a pull on the proximal end thereof, so that by pulling on the pull the loop can be drawn tightly about a tissue to be ligated. An electrosurgical wire is slidably received in the first channel and has an electrically insulated body extending through the first channel with an exposed wire hook formed at the distal end thereof for grasping the tissue to pull it through the suture loop. An electrical connector is attached to the proximal end thereof for connection to a source of electrosurgical power. A ligation assist device is slidably received in the second channel which may be in the form of a hypodermic needle for providing anesthesia to the tissue to be ligated or in the form of an optical fiber for carrying laser energy for fulgurating the ligated tissue.
