A reverse-type nucleus chopping hook for cataract surgery. The nucleus chopping hook is made from a titanium alloy material, and comprises a hook handle (1) and a hook body (2) connected to the hook handle (1) as an integrated structure, several longitudinal anti-slide ridges (11) being distributed along the axial direction of the surface of the hook handle (1), a rear section of the hook body (2) extending along the axial direction of the hook handle (1), a front section of the hook body bending upwards as a whole, an end portion of the front section of the hook body (2) bending downwards and forming a curved hook (21) by bending inwards, the curvature of the curved hook (21) increasing incrementally with the extension of the curved hook (21), two ends of the curved hook (21) being rounded structures, the linear distance between the two ends of the curved hook (21) being 2.2-2.6 mm, the inside of the curved bend of the curved hook (21) being provided with a blade (211). The reverse-type nucleus chopping hook for cataract surgery has a reasonable structure, operates in a safe and reliable manner, grasps a nucleus firmly, chops the nucleus more thoroughly, and has a high nucleus chopping efficiency. The titanium alloy material has advantages such as high strength, good corrosion resistance and high heat resistance, so that the nucleus chopping hook may be re-used after being thoroughly sterilised, thereby ensuring the reasonable allocation of resources.Linvention concerne un crochet de taille de noyau de type inverse pour la chirurgie de la cataracte.
