PROBLEM TO BE SOLVED: To provide an intraocular lens injector which suppresses changes in an operation pressure during normal operation while the push-out operation of an intraocular lens is carried out and facilitates the determination of whether the push-out operation is normal or not.SOLUTION: The intraocular lens injector includes an interference part which is provided in a passage of a push-out rod and makes contact with the push-out rod to generate frictional force between the interference part and the push-out rod to apply a prescribed operation pressure to the push-out rod while the intraocular lens is pushed out by the push-out rod toward an insertion part for inserting the intraocular lens in an eye. The push-out rod is characterized in that a region in the axial direction of the push-out rod relative to the interference part in a range where a diameter of the intraocular lens is reduced by an internal shape of the insertion part with the frictional force generated by the contact between the insertion part and the intraocular lens increased is treated or formed to reduce the frictional force with the interference part or is configured to have a shape to prevent the contact between the push-out rod and the interference part in the region.COPYRIGHT: (C)2009,JPO&INPIT【課題】 眼内レンズの押し出し動作において正常な動作中の作動圧の変化を抑制し、正常動作中なのか否かを判断しやすい眼内レンズ挿入器具を提供する。【解決手段】 押出棒の通路内に設けられる干渉部で押出棒により眼内レンズを眼内に挿入する挿入部に向けて押し出す間,押出棒に対して所定の作動圧を与えるために押出棒に接触し押出棒との間で摩擦力を発生させる干渉部を有し、押出棒は、挿入部の内形状により眼内レンズがさらに小さい径とされ挿入部と眼内レンズとの接触により生じる摩擦力が増大する範囲における干渉部に対する押出棒の軸方向の領域が干渉部との摩擦力を減少させるための処理または形状,若しくは領域において押出棒と干渉部とを接触させないための形状が形成されていること。【選択図】 図6
