1. An electrosurgical system comprising:
- an electrosurgical generator arranged to output electrosurgical energy; and
a bipolar electrosurgical tool removably coupled to the electrosurgical generator, the tool comprising;
a stationary handle; and
an actuation handle movably coupled to the stationary handle;
a rotatable elongate shaft extending distally from the stationary handle and rotatable relative to the stationary handle, the rotatable elongate shaft having a proximal end and a distal end defining a central longitudinal axis therebetween;
a jaw assembly pivotably connected and positioned at the distal end of the rotatable elongate shaft, the jaw assembly comprising an upper jaw having an inner surface, an outer surface, and an electrode disposed on the inner surface of the upper jaw and a lower jaw having an inner surface, an outer surface, an electrode disposed on the inner surface of the lower jaw and a lower spacer disposed adjacent to the electrode, the upper and lower jaws actuatable by movement of the actuation handle from an open configuration in which the inner surface of the upper jaw is spaced apart from the inner surface of the lower jaw to a closed configuration in which the inner surface of the upper jaw is proximate the inner surface of the lower jaw, arranged to contact tissue and apply the electrosurgical energy to the tissue,wherein the electrosurgical generator supplies electrosurgical energy from the electrosurgical generator through the electrode disposed on the inner surface of the upper jaw of the bipolar electrosurgical tool and the electrode disposed on the inner surface of the lower jaw of the bipolar electrosurgical tool, the supplied electrical energy has a potential difference of no more than 200V, and the electrode disposed on the inner surface of the upper jaw has a tissue contact area equal to a tissue contact area of the electrode disposed on the inner surface of the lower jaw.

Abstract
An electrosurgical system can include an electrosurgical generator, a feedback circuit or controller, and an electrosurgical tool. The feedback circuit can provide an electrosurgery endpoint by determining the phase end point of a tissue to be treated. The electrosurgical system can include more than one electrosurgical tool for different electrosurgical operations and can include a variety of user interface features and audio/visual performance indicators. The electrosurgical system can also power conventional bipolar electrosurgical tools and direct current surgical appliances.
