Patent

CA 2283469

An instrument for the insertion of an intraocular lens into an eye comprises a body portion, a nose portion (114) through which runs a passage for the lens to pass to a dispensing tip, and a plunger. The nose portion is preferably pivotally connected to the body portion so that the barrel can be broken open for the placement of the lens into the nose portion. The lens (504) is preferably placed on two spaced parallel nose pins (308) to facilitate its folding. A cross pin (304) preferably straddles the nose pins (308) and under which the lens is arranged to pass, to prevent lifting and tilting of the lens.

L'invention concerne un instrument permettant d'insérer une lentille intra-oculaire dans un oeil, lequel instrument comprend une partie corps, une partie embout (114) que traverse un passage permettant à la lentille de passer vers une pointe de distribution, et un piston. La partie embout est, de préférence, reliée pivotante à la partie corps de manière que le cylindre puisse être ouvert par rupture pour permettre la mise en place de la lentille dans la partie embout. La lentille (54) est, de préférence, placée sur deux broches (308) séparées parallèles de l'embout, ce qui la rend plus facile à plier. Une broche (304) traversante chevauche, de préférence, les broches (308) de l'embout et la lentille est disposée pour passer sous cette broche, de manière à ce qu'elle ne puisse pas se soulever ou s'incliner.
