Patent

CA 2541845

Phacoemulsification apparatus includes a phacoemulsification handpiece having a needle and an electrical circuitry for ultrasonic vibrating the needle. A power source provides pulsed electrical power to the handpiece electrical circuitry and an input is provided for enabling a surgeon to select an amplitude of dislighted pulses and a pulse width. A control system and pulse duty cycle is provided for controlling the off duty cycle to insure heat dissipation before a subsequent pulse is activated, including a foot pedal switch.

Un appareil de phaco-émulsification prend un instrument à main de phaco-émulsification comprenant une aiguille et un circuit électrique destiné à faire vibrer dans les ultrasons cette aiguille. Une source électrique fournit une puissance électrique par impulsions à ce circuit électrique d'instrument à main et une entrée est fournie de façon à permettre au chirurgien de sélectionner une amplitude d'impulsion et une longueur d'impulsion. Un système de commande et un cycle de travail d'impulsions permet de commander le cycle hors travail de façon à assurer la dissipation de chaleur avant qu'une impulsion suivante soit commandée, ce système comprenant un commutateur à pédale.
