FIELD: medical engineering.
SUBSTANCE: device has hollow cylindrical casing and working tip. The hollow cylindrical casing wall thickness is not less than 5 mm and the working tip is removable as nozzle having convex hemisphere and adjacent cylindrical part. External diameter of the cylindrical part is equal to internal diameter of the hollow cylindrical casing. Cone is available in the cylindrical part of the nozzle. Concave surface as hemisphere of smaller diameter is available in the convex hemisphere. Distance between the cone apex in the cylindrical nozzle part and inferior point of the concave contact surface is not greater than 3 mm.
EFFECT: accelerated eyeball content fixation with ice crystals.
