Zusammenfassung:	The present invention relates to a cannula for microsurgery. According to the invention, the suction tube (2) of a cannula is formed in such a way that the cross-sectional surface area of its passage increases in a uniform manner starting from its free end (5) in the direction of its attachment head (1). The invention is used in particular in ophthalmology for cataract extraction, for the purpose of removing the material of the crystalline lens. La présente invention concerne une canule pour opérations de microchirurgie. Selon l'invention, le tube d'aspiration (2) d'une canule est réalisé de façon que l'aire de sa surface transversale de passage augmente d'une manière monotone à partir de son extrémité libre (5) en direction de sa tête d'adaptation (1). L'invention s'applique notamment en ophtalmologie pour l'extraction de la cataracte, en vue d'évacuer les masses du cristallin.
