Abstract
Un instrumento electroquirurgico, que se usa para tratar tejido en presencia de un fluido eléctricamente conductivo (por ejemplo, "cirugía bajo el agua"), comprende un eje del instrumento y un ensamble de electrodos en un extremo del eje. El ensamble de electrodos comprende un electrodo de tratamiento de tejido (11) y un electrodo de retorno (12) que está asilado eléctricamente del electrodo de tratamiento de tejido mediante un miembro aislante (15). EL electrodo de tratamiento de tejido (11) se expone en el extremo distal terminal del instrumento, y el electrodo de retorno (12) tiene una superficie de contacto con el fluido separada del extremo del electrodo de tratamiento de tejido mediante un miembro aislante (15). El instrumento comprende además elementos de alimentacion (17) para alimentar el fluido eléctricamente conductivo a la region del extremo expuesto del electrodo de tratamiento de tejido (11) de manera de definir, durante el uso, una trayectoria del fluido conductivo que completa un circuito eléctrico entre el electrodo de tratamiento del tejido y el electrodo de retorno (12).
