Abstract

Un aparato de control de potencia para un generador electroquirurgico se usa para controlar la potencia de salida de un generador al tejido o fluidos corporales de un paciente; el aparato de control determina rápidamente la gama de impedancias de la carga sobre el generador electroquirurgico y ajusta la potencia de salida en conformidad; la corriente de salida y la tension de salida del generador electroquirurgico son monitoreadas y enviadas a un microprocesador; el microprocesador opera un algoritmo que determina rápidamente la gama de impedancias de la carga sobre el generador; el algoritmo utiliza técnicas computacionales, tales como comparaciones y desplazamiento de bits, que evitan divisiones largas y otras operaciones que consumen tiempo; de esta manera, el microprocesador puede ajustar una fuente de energía de alto voltaje que efectua la etapa de amplificadora de radiofrecuencia; también se describe un método para controlar la potencia del generador electroquirurgico, incluyendo etapas en el algoritmo.
