Abstract

GENERADOR ELECTROQUIRURGICO PARA REALIZAR OPERACIONES QUIRURGICAS MEDIANTE CORRIENTES DE RADIOFRECUENCIA. EL GENERADOR UTILIZA CIRCUITERIA DE ESTADO SOLIDO PARA PRODUCIR EL ALTO VOLTAJE NECESARIO PARA LA FULGURACION. DICHA CIRCUITERIA MEJORA LA FORMACION DE ARCO INICIAL PRODUCIENDO UNA FORMA DE ONDA DE CIRCUITO ABIERTO, ANTES DE LA FORMACION DEL ARCO, SOBRE EL ELECTRODO ACTIVO, PRACTICAMENTE SINUSOIDAL. EL FACTOR AMORTIGUADOR DE LA FORMA DE ONDAS ES AJUSTADO PARA SER LO MENOR POSIBLE, DE MODO QUE BAJO CONDICIONES DE CIRCUITO ABIERTO TENGAN LUGAR MUCHOS CICLOS ANTES DE QUE LA FORMA DE ONDAS DESCIENDA A CERO DURANTE CUALQUIER PERIODO DE TIEMPO SIGNIFICATIVO.
