Abstract

Se describen un método y aparato de electro-cirugía. En el método, tejido es cortado o coagulado con un fluido de baja conductividad eléctrica que proporciona enfriamiento. En otro método, piel es cortada mediante electro-cirugía en un campo seco usando una señal de bajo ciclo de trabajo que energiza al electrodo de corte, minimizando la carbonización del tejido. Un electrodo combinado de coagulación y corte lleva a cabo ambas funciones. El corte se lleva a cabo por un borde de hoja que genera un plasma local adaptado para el corte. Sobrepuesto en el borde de hoja está un electrodo de área superficial más grande aislado eléctricamente del electrodo de corte, para coagulación. En otra versión, una hoja (electrodo) de corte/coagulación de un solo componente tiene un borde de corte y una porción plana parcialmente aislada que define orificios de paso en el aislamiento para coagulación. También se proporciona un circuito eléctrico con lo cual cada electrodo es aislado por un filtro de la diafonía y retroalimentación de la señal de RF proveniente del otro electrodo, minimizando la formación de arco.
