摘要：
Provided is an intraocular lens injector that allows a haptic and a optic to be pushed in reliably. The intraocular lens injector includes a lens holder holding an intraocular lens which has a optic and a haptic extending in a curved shape from the optic, a device body to which the lens holder is attached, a plunger inserted projectably/retractably in the device body and coming into contact with the intraocular lens to push out this intraocular lens, and a nozzle portion connected to the device body, the nozzle portion releasing the intraocular lens while folding the intraocular lens concavely by a push-in operation of the plunger. A positioning mechanism is provided to push up the haptic along a thickness direction of the optic within a range contactable with a distal end of the plunger, when the lens holder and the intraocular lens are attached to the device body.提供一種可以確實地推入支撐部和鏡片部的眼內鏡片用植入器。該眼內鏡片用植入器具備:鏡片保持具,其係保持具有鏡片部及從鏡片部延伸出成曲線狀之支撐部的眼內鏡片;及裝置本體,其係可安裝鏡片保持具;及柱塞,其係可進退地內插於裝置本體,用來抵接於眼內鏡片以將眼內鏡片推出;以及嘴部,其係連接於裝置本體,且一邊利用柱塞之推入操作將眼內鏡片摺疊成凹狀一邊將眼內鏡片放出;且具備定位機構,其係在將鏡片保持具及眼內鏡片裝設於裝置本體時,將支撐部在能夠與柱塞之前端部抵接的範圍內朝向鏡片部之厚度方向往上推。2‧‧‧裝置本體24‧‧‧凸部(定位機構)24a‧‧‧第1凸部(定位機構)24b‧‧‧第2凸部(定位機構)3‧‧‧前端構件4‧‧‧鏡片保持具431‧‧‧彎曲部46‧‧‧插通部(定位機構)5‧‧‧柱塞7‧‧‧眼內鏡片7a‧‧‧鏡片部7b‧‧‧前方支撐部(支撐部)7c‧‧‧後方支撐部(支撐部)
