Abstract:
1. A bipolar electrosurgical instrument to treat tissue in the presence of radio frequency energy and an electrically conductive fluid provided simultaneously from the instrument, the instrument comprising: a distal portion comprising a first tube and a second tube, a first electrode and a second electrode, and a first fluid exit opening and a second fluid exit opening; the first electrode spaced from the second electrode, the first electrode and the second electrode both uncovered to treat tissue adjacent thereto; the first electrode located at a distal end of the first tube and the second electrode located at a distal end of the second tube; the first fluid exit opening positioned to dispense fluid adjacent the first electrode and the second fluid exit opening positioned to dispense fluid adjacent the second electrode; and the distal portion arranged to facilitate a reduction in a fluid interaction between a fluid dispensed from the first fluid exit opening and a fluid dispensed from the second fluid exit opening when treating the tissue with the instrument.
