PROBLEM TO BE SOLVED: To provide an intraocular lens injection instrument of simple structure that controls damages to a support caused by a plunger.SOLUTION: The intraocular lens injection instrument has an insertion part internally structured to insert an intraocular lens through an incision and fold it up while it moves within the insertion part, a placing part positioned at the bottom end of the insertion part to keep the lens from stresses, a tubular injector body having the insertion part and the placing part ahead of it, and a plunger means having a flexible push rod movably provided within the injector body to push out the lens off the insertion part along the movement axis. A guide means is also provided behind the placing part to guide the push rod, located on a different axis from the lens movement axis, in its advance and retreat direction, so that it can move along the movement axis, its end can bend before touching the optical part of the lens, and position between the optical part put on the placing part and the support behind it.COPYRIGHT: (C)2009,JPO&INPIT【課題】 簡単な構成でプランジャによる支持部の損傷を抑制する。【解決手段】 眼内レンズを切開創から挿入し,挿入部内を移動する眼内レンズを折り畳む内部形状を備える挿入部と、挿入部の基端に設けられ応力を掛けない状態で眼内レンズを載置する載置部と、挿入部及び載置部を先端に持つ筒構造の挿入器具本体と、挿入部から眼内レンズを移動軸上にて押し出すために挿入器具本体の筒内で進退移動可能に設けられ,柔軟性を有する押出棒を備える押出手段と、を備える眼内レンズ挿入器具で、載置部の後方に設けられ押出棒の進退移動方向をガイドするガイド手段であって,移動軸と異なる軸上に位置する押出棒を光学部に接触する前に屈曲させるfr載置部に載置される眼内レンズの光学部と後側の支持部との間に押出棒の先端を位置させ,移動軸上を押出棒が進退移動するようガイドするガイド手段を有する。【選択図】 図3
