CA 2214566

A surgical instrument for removing tissue, such as a cataract, from a patient's body includes a hollow, vibrating needle surrounded by one or two hollow infusion sleeves. Reducing friction between the surfaces of the sleeves and the outer surface of the needle, and/or surrounding ocular tissue, dramatically reduces the amount of heat generated during surgery, thus reducing the possibility of thermal damage to tissue.

Un instrument chirurgical pour exciser un tissu chez un patient, par exemple la cataracte, comprend une aiguille vibrante creuse (16) entourée par un ou plusieurs manchons creux (18) d'injection de fluide. En diminuant la friction entre les surfaces des manchons et la surface externe de l'aiguille (18) et/ou le tissu oculaire environnant, on diminue d'une manière très importante la chaleur produite durant l'opération, ce qui diminue les risques de détérioration des tissus par la chaleur.
