Abstract

LA INVENCION SE REFIERE A UN METODO Y APARATO MEJORADOS UTILIZADOS PARA CONTROLAR LA FRAGMENTACION ULTRASONICA DE LOS TEJIDOS DEL CUERPO. EL APARATO ULTRASONICO CONSTA DE UN EQUIPO TRANSDUCTOR MONTADO EN UN CONJUNTO APLICADOR. EL TRANSDUCTOR FUNCIONA PARA CONVERTIR LA POTENCIA ELECTRICA EN UNA ENERGIA VIBRACIONAL MECANICA ULTRASONICA. HAY UN DISPOSITIVO AMPLIFICADOR VIBRACIONAL ACOPLADO AL EQUIPO TRANSDUCTOR QUE TIENE PARTES CON BOCINAS ASIMETRICAS EN SERIE Y PARTES CON BOCINAS SIMETRICAS. EN UNA DE LAS PARTES DE BOCINA HAY UNA PUNTA OPERATORIA.
