Abstract

El aparato y los métodos asociados se refieren al control de la energía eléctrica de una señal electroterapéutica que se proporciona a un tejido biológico comprometido por un instrumento electroquirúrgico durante un procedimiento médico. La energía eléctrica, producto de una diferencia de voltaje a través y una corriente eléctrica conducida por el tejido biológico comprometido, se controla de acuerdo con un programa terapéutico. El programa electroterapéutico puede reducirse o terminarse en respuesta al cumplimiento de un criterio de terminación. En algunos ejemplos, el criterio de terminación es una característica actual como, por ejemplo, una disminución de la corriente conducida por el tejido biológico comprometido. En algunos ejemplos, el criterio de terminación es una característica de resistencia biológica del tejido, como, por ejemplo, un aumento en la resistencia biológica del tejido que supera un valor de resistencia delta predeterminado
