Claims13
An electrosurgical instrument comprising:
- (a) a first arm carrying a first and second electrode and having a top edge, a bottom edge and two substantially parallel side edges such that one or more of the first and second electrodes extends from the bottom edge and beyond the top edge of the first arm and wherein the top edge and bottom edge are substantially parallel to one another and the bottom edge is an inside edge of the first arm adjacent the second arm;
- (b) a first, second and third insulating portion located on the first arm, the second insulating portion arranged so that it is coextensive with and located in between the first and second electrode, the first and third insulating portions also arranged coextensive with the first and second electrode but free of any contact with the second insulating portion;
- (c) a second arm opposing the first arm, the second arm carrying a single conductive element and a first and second insulating portion, the first and second insulating portions being free of direct contact with one another;
- wherein the conductive element is a floating electrode and opposes both the first electrode and the second electrode and wherein the floating electrode is offset from and does not permanently align with the first or second electrode on the first arm.
