Abstract

Un generador electroquirurgico arreglado para suministrar potencia de radio frecuencia a un instrumento electroquirurgico bipolar (12) para la coagulaciono desecacion de tisu, el generador comprende un estadio de salida de radio frecuencia (60) con,por lo menos un par de conexiones de salida electroquirurgica(62) para la distribucion de potencia de radio frecuencia al instrumento, un suministro de potencia (66) acoplado al estadio de salida para suministrarpotencia al estadio de salida y un circuito de control (68, 70, 72) incluyendo un medio de deteccion (68) para detectar el voltaje de salida de radiofrecuencia desarrollado a través de las conexiones de salida, el circuito de control es operable para determinar si el voltaje de salida haalcanzado un umbralpredeterminado y automáticamente para reducir la potencia de radio frecuencia en respuesta al alcance del umbral predeterminado, caracterizado porque cuando seopera para realizar la coagulacion o desecacion de tisu, a un voltaje suministrado determinado, la característica de impedancia de carga versus la potencia desalida del generador (60) posee un pico de potencia de salida a un voltaje de radio frecuencia menor que el umbral de voltaje predeterminado, así facilitandola rápida reduccion en la potencia de salida de radio frecuencia cuando se obtiene el umbral. La presente invencion además contempla un sistemaelectroquirurgico que incluye a dicho generador.
