ABSTRACT:
A bipolar electrosurgical instrument for cutting and coagulating tissue is disclosed. Also disclosed is a method for using the bipolar electrosurgical instrument. The instrument includes particular patterns of electrically conductive portions and electrically non-conductive portions on the interior surfaces of the shearing members such that the electrical current is localized in the tissue to be treated without causing a short circuit in the instrument. Other advantages of the device include an improved cutting ability aided by the localized electrical current and reduced manufacturing costs as compared to similar, prior art devices.
