Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a configuration effectively preventing axial shift of a plunger inside a lens holder in the lens holder of an injector for an intraocular lens.SOLUTION: A lens holder 4 of an injector for an intraocular lens includes: a holder body 61 having a mount unit 62 on which an optical unit 91 of an intraocular lens 90 is placed, and including an insertion hole 63 for a plunger 3 formed at a proximal side thereof, the plunger for pushing out the optical unit 91 positioned on the mount unit 62 toward the distal side; and an axial-shift-preventing unit 110 provided between the mount unit 62 and the insertion hole 63 inside the holder body 61 and in the movement path of the plunger 3, the axial-shift-preventing unit being an elastic member that deforms in conformity with the shape of the plunger 3 when the plunger 3 moves toward the distal end.SELECTED DRAWING: Figure 2
【課題】眼内レンズ用インジェクタのレンズホルダにおいて、レンズホルダ内部でのプランジャの軸ブレを効果的に防止できる構成を提供すること。【解決手段】眼内レンズ用インジェクタのレンズホルダ4は、眼内レンズ90の光学部91をセットする載置部62を有し、載置部62にセットされた光学部91を先端側に押し出すプランジャ3の挿入口63が基端側に形成されるホルダ本体61と、ホルダ本体61の内部における載置部62と挿入口63の間であってプランジャ3の移動経路に設けられ、プランジャ3が先端側に移動すると該プランジャ3の形状に追従して変形する弾性部材としての軸ブレ防止部110と、を備える。【選択図】図2 |
