Abstract

Una conexión de termístor para un instrumento quirúrgico cortador y/o de coagulación en la forma de un puente de resistencias conectado a una tensión de alimentación, en el cual está empalmada una diagonal con un comparador, y en el cual se efectúa una conexión intermitente del circuito de alimentación con un interruptor gobernado, después de alcanzarse por primera vez el valor nominal, caracterizada porque la salida del comparador está unida a través de una resistencia, con una entrada de mando del interruptor gobernado, y está dispuesto un condensador paralelamente a la entrada de control del interruptor, y porque uno de los medios puentes está conectado constantemente y el otro medio puente está conectado de forma intermitente, a través del interruptor, a la tensión de alimentación del puente.
