Abstract
A bipolar electrosurgical handpiece, and electrode for use with the handpiece, that is configured for use in MIS and other electrosurgical procedures. The handpiece is constructed with a flexible end controllable by the surgeon so as to allow the surgeon to manipulate the end as desired during the surgical procedure. The electrode is housed in a tubular member. The electrode ends comprise bare loops projecting from the end of the housing in spaced parallel planes. When energized, a bipolar discharge is generated between the bare loops.
Claims9
An electrosurgical handpiece comprising:
- (a) an elongated tubular first member having a first end and a distal flexible second end,
- (b) first and second electrically-conductive wires fixedly positioned in electrically-insulating relationship in the first member with first means connected to the first member at its first end for applying to the first and second wires a bipolar electrosurgical voltage capable of generating electrosurgical currents between the wires, each of the first and second wires having a bare end forming a loop projecting out of the first member at its second end,
- (c) the bare end loops of the first and second wires extending in laterally-spaced parallel planes whose relative position in the spaced parallel planes remains fixed whether or not the second end is flexed,
- (d) wherein electrosurgical currents are generated between the spaced bare end parallel loops when the electrosurgical voltage is applied to the first and second wires.

An electrosurgical electrode comprising:
- (a) an elongated tubular first member having a first end and a distal second end,
- (b) first and second fixed electrically-conductive wires positioned in fixed electrically-insulating relationship in the first member, each of the first and second wires having a bare end forming a loop projecting out of the first member at its second end,
- (c) the bare end loops of the first and second wires extending in laterally-spaced parallel planes whose relative position in spaced parallel planes remains fixed whether or not the second end is flexed,
- (d) wherein electrosurgical currents can be generated between the spaced bare end parallel loops when an electrosurgical voltage is applied to the first and second wires.
