INTRAOCULAR LENS INSERTION DEVICE

摘要

The intraocular lens insertion tool includes a nozzle main body having a nozzle portion 15, a stage portion capable of disposing the intraocular lens 2 in the nozzle main body, and a plunger 60 that presses the intraocular lens 2 set in the stage portion by a leading end, thereby releasing the intraocular lens 2 into an eyeball. The leading end portion 10a of the nozzle portion 15 is obliquely cut so that, as it goes to the front side from the optical axis rear side of intraocular lens 2, the position of the end surface is located on the front side, and at the leading end 61d of the plunger 60, a protruding portion 61e is provided which protrudes to the front side so as to be able to place the surface of the optical axis rear side of the intraocular lens 2.

主权项

1. An intraocular lens insertion device comprising:
a device main body that has an insertion tube to be inserted into an incision formed in an ocular tissue and is formed in a substantially cylindrical shape; a housing portion that is provided integrally or separately in the device main body and is able to dispose the intraocular lens in the device main body by housing the intraocular lens; and a plunger that is pushed to the device main body and presses the intraocular lens housed in the housing portion by a leading end, thereby releasing the intraocular lens from the leading end of the insertion tube into an eyeball, the intraocular lens being inserted into the eyeball by releasing the intraocular lens from the leading end of the insertion tube inserted into the eyeball from the incision into the eyeball, wherein the leading end of the insertion tube is obliquely cut so that its partial region is located on a front side in an insertion direction of the intraocular lens, and at the leading end of the plunger, in a portion on an opposite side to the region of the leading end of the insertion tube when viewed from the front side in the insertion direction of the intraocular lens when inserting the intraocular lens, a protruding portion is provided which protrudes to the front side in the insertion direction of the intraocular lens so as to be able to place a part of the intraocular lens.
