Abstract

En un instrumento electroquirurgico para el tratamiento de tejido en presencia de un medio fluido eléctricamente conductivo (por ejemplo "cirugía bajo el agua") un ensamble de electrodos bipolar tiene un electrodo activo que tiene una porcion de tratamiento de tejido expuesta (34A), un electrodo de retorno (38) que tiene una superficie de contacto con el fluido expuesta, y un miembro aislante (36) colocado entre y aislando eléctricamente el electrodo activo y el electrodo de retorno. EL miembro de aislamiento sirve para separar la porcion de tratamiento del electrodo activo y la porcion de contacto con el fluido del electrodo de retorno. Las dimensiones y configuraciones de las porciones expuestas de los electrodos y del miembro de aislamiento son tales que cuando el ensamble de electrodos está sumergido en un medio fluido conductivo, la proporcion entre las longitudes de trayectoria de conduccion más larga y más corta entre los electrodos activo y de retorno (b:a) es menor que o igual a 2:1. La invencion también incluye una combinacion de un instrumento electroquirurgico y un generador de radiofrecuencia.
