CARTRIDGE OF SYSTEM OF INTRAOCULAR LENS INTRODUCTION Russian patent published in 2012 - IPC A61F2/16 

FIELD: medicine.

SUBSTANCE: invention relates to medicine. Cartridge of system of intraocular lens introduction contains case and tubular nozzle, connected with case and projecting outside with respect to case. Nozzle has modified elliptical transverse section with interface curves, where modified elliptical transverse section has shape, determined by means of part of ellipse, which has the centre, which is displaced from the origin of Cartesian coordinate system, and said part of ellipse is located in the first quadrant and second quadrant of Cartesian coordinate system, with said part of ellipse being determined as upper curve; and lower curve, determined as precise representation of upper curve around x-axis of Cartesian coordinate system, and upper curve and lower curve form points of bend in the place where upper curve and lower curve cross x-axis of Cartesian coordinate system; and interface curves, formed on opposite ends of said elliptical shape near the points of bend, with each interface curve being defined as part of circumference, connecting upper curve and lower curve, that is being tangent to both upper and lower curves and has tangent line passing at 90° in point of crossing x-axis by interface curves.

EFFECT: invention provides possibility of intraocular lens introduction through relatively small cut with minimal trauma to tissues.
