SYSTEMS AND PROCESSES FOR INSERTING AN INTRAOCULAR LENS Russian patent published in 2018 - IPC A61F9/07 A61F2/16 

FIELD: medicine.

SUBSTANCE: system for inserting an intraocular lens comprises: lens chamber adapted to receive an intraocular lens; delivery cartridge coupled to the lens chamber and adapted to fold and compress an intraocular lens as the intraocular lens is moved therethrough; plunger adapted to be manipulated by a user; plunger chamber adapted to allow the plunger to be moved therein along a longitudinal axis and move a plunger tip along the longitudinal axis; and a plunger tip chamber adapted to house a first plunger tip and a second plunger tip and to alternately switch between alignment of the first plunger tip and the plunger and alignment of the second plunger tip with the plunger. Wherein the plunger tip chamber is laterally moveable so as to alternatingly align the first plunger tip and the second plunger tip with the plunger. Method for inserting an intraocular lens comprises: moving, in response to a force being applied in a first direction along a longitudinal axis, a first plunger tip along the longitudinal axis and into a delivery cartridge to fold an intraocular lens; moving in a second direction along the longitudinal axis in response to the applied force being reduced; engaging a second plunger tip and moving, in response to a force being applied in the first direction along the longitudinal axis, the second plunger tip along the longitudinal axis and into the delivery cartridge to compress the intraocular lens. Wherein engaging a second plunger tip comprises altering which plunger tip is aligned with the longitudinal axis.

EFFECT: use of this group of inventions will provide wider range of technical means allowing inserting an intraocular lens.
