Abstract

See full text

Embodiments of the disclosed technology relate to a bipolar electrosurgical device for a laparoscopic environment, as well as methods for the use of such a device. Embodiments of the device may include a set of opposing jaws comprising at least one bipolar electrode pair disposed thereon, the set of jaws configured to deliver radiofrequency energy to a target tissue. Embodiments of the set of jaws, when closed, may have a diameter no greater than about 5 mm. The device may further include a shaft with a diameter that may be no greater than about 5 mm. Each of the jaws has a tissue-facing surface of each jaw that may include a complementary self-aligning configuration with respect to the longitudinal axis of the other jaw. Embodiments of the device may further include a pinless rotation assembly formed from rotatably cooperative features of the first jaw and the second jaw that connect the jaws together and enable the jaw set to pivot between an open position and a closed position.
