Title (EN) AN APPARATUS AND METHOD FOR PERFORMING OPHTHALMIC PROCEDURES
(FR) DISPOSITIF ET PROCEDE A USAGE OPHTALMIQUE
Abstract:
(EN) This invention is a surgical cutting system. The cutting system includes a cutter (10) which has an inner sleeve (18) that moves adjacent to an aspiration port of an outer sleeve (12). The inner sleeve is coupled to a source of vacuum that pulls tissue into the outer port (14) when the inner sleeve is moved away from the port. The inner sleeve then moves across the outer port and severs the tissue in a guillotine fashion. The inner sleeve may have circumferential slits (112, 130) that allows the sleeve to bend into the aspiration port during the cutting stroke of the cutter. The cutter includes a motor (24) which creates an oscillating translational movement of the sleeve. The motor speed can be controlled by a foot pedal and a controller that automatically varies the electrical power provided to the motor to compensate for different loads on the cutter. The cutter may contain electrodes that are connected to an electrical generator. The generator provides electrical energy to the cutter and adjoining tissue. A surgeon can thus both cut and cauterize with the same device.
(FR) L'invention concerne un système d'incision chirurgicale. Le système comprend un instrument tranchant (10) qui a un manchon intérieur (18) se déplaçant en position adjacente par rapport à l'entrée d'aspiration d'un manchon extérieur (12). Le manchon intérieur est relié à une source d'aspiration qui tire le tissu à travers l'orifice extérieur (14) lorsque le manchon intérieur est éloigné de l'orifice. Ensuite, le manchon intérieur chevauche l'orifice extérieur et coupe le tissu à la manière d'une guillotine. Le manchon intérieur peut avoir une ou plusieurs fentes de pourtour (112, 130) lui permettant de s'incurver dans l'orifice d'aspiration pendant l'incision. L'instrument tranchant comprend un moteur (24) qui confère un mouvement de translation oscillatoire au manchon. On contrôle la vitesse du moteur au moyen d'une pédale et d'un régulateur qui modifie automatiquement la puissance électrique d'alimentation pour compenser les différentes charges sur l'instrument tranchant. Cet instrument peut comporter des électrodes reliées à un générateur électrique; par l'énergie électrique ainsi fournie à l'instrument proprement dit et au tissu avoisinant, le chirurgien peut couper et cautériser avec un seul dispositif.
