DEVICE FOR IMPLANTATION OF FLEXIBLE ARTIFICIAL LENS OF EYE Russian patent published in 1999 - IPC

FIELD: medical engineering, namely ophthalmologic instruments. SUBSTANCE: base of device body is made as hollow cylinder with oval section turning continuously into narrowing cone and then into operating part shaped as hollow cylinder. Piston is made integral with rod, and operating part of piston provided with circular recess carries attachment. The latter has circular projection for fixing in piston recess. Piston is capable of longitudinal displacement relative to attachment. Diameter of piston operating part is equal to internal diameter of body operating part. Cross- section of attachment corresponds to internal section of body base. Attachment may be made as concentric parts inserted into each other. Paris may be shifted relative to each other longitudinally of principle of telescopic antenna. Every part of attachment is provided with circular recess on its external side surface, and its internal side surface has circular projection for fixing of parts in each other. EFFECT: reduced traumatization of coating. 2 cl, 10 dwg
