Abstract

Un instrumento electroquirúrgico que es utilizado para el tratamiento de tejido en presencia de un medio fluido conductor de electricidad comprendeun mango de instrumento (10), y un conjunto de electrodos (12) en un extremo del mango. Elconjun to de electrodos (12) comprende un electrodo detratamiento tisular (14) y un electrodo de retorno (18) que está aislado eléctricamente del electrodo de tratamiento tisular mediante un miembro deaislación (16). El electrodo detratamiento tisul ar (14) tiene un extremo expuesto para tratar tejido, y el electrodo de retorno (18) tiene unasuperficie de contacto fluido que está espaciada del electrodo de de tratamiento tisular de tal manera de definir, enuso, un recorrido dede fluido conductor que completa un circuito eléctrico entre el electrodo de de tratamiento tisular y el electrodo de retorno. El conjunto de electrodos(18) está provisto de una pluralidad de aberturas (14a) en la región del electrodo de tratamiento tisular (14), aberturas a través de las cuales sepueden aspirar las burbujas de vapor y/o el material particulado de la región que rodea al electrodo de tratamiento tisular.
