Abstract

Sistema de facoemulsificación oftálmica, que comprende: una pieza de mano (1150) que incluye una aguja o punta de corte (1210), y unos medios ultrasónicos para hacer vibrar la punta de corte hacia delante y hacia atrás con el fin de producir una carrera de aguja longitudinal, y de hacer vibrar la punta de corte en un movimiento de retorcimiento o torsional; unos medios (1160) para medir una presión de vacío en un conducto de aspiración (1155); estando dicho sistema adaptado para proporcionar una serie de impulsos de potencia a la pieza de mano, presentando cada uno de la serie de impulsos de potencia: una primera parte que produce un movimiento torsional de una punta de corte; una segunda parte que produce un movimiento longitudinal y torsional simultáneo de la punta de corte; y una tercera parte que produce un movimiento longitudinal de la punta de corte; estando dicho sistema adaptado para alterar la duración de la primera parte de la serie de impulsos de potencia como respuesta a un incremento de una presión de vacío medida; y estando dicho sistema adaptado para alterar la duración de la segunda parte de la serie de impulsos de potencia como respuesta a un incremento de una presión de vacío medida; y estando dicho sistema adaptado para alterar la duración de la tercera parte de la serie de impulsos de potencia como respuesta a un incremento de una presión de vacío medida.
