Description
本発明は、眼内レンズを眼内に挿入する眼内レンズ挿入器具に関する。 The present invention relates to intraocular lens insertion device for inserting an intraocular lens into the eye.
本開示は、眼内レンズを好適に折り曲げることが可能な眼内レンズ挿入器具を提供することを目的とする。 An object of this indication is to provide the intraocular lens insertion instrument which can bend an intraocular lens suitably.
上記課題を解決するために、本開示に係る眼内レンズ挿入器具は、以下のような構成を備える。
（１） 光学部と、前記光学部の周囲から外側に延びる一つまたは複数のループ状の支持部とを有する変形可能な眼内レンズを棒状の押出部材を押出軸に沿って進行させることで、眼内に挿入する眼内レンズ挿入器具であって、前記押出部材によって押し出される前記眼内レンズが所定の方向に向けて設置される設置部と、前記押出軸と平行な方向に直線移動することで、前記支持部を前記光学部に近づく方向に移動させる直線移動部とを備え、前記押出軸に対して前記設置部に設置される前記眼内レンズの前記支持部の基端が位置する方向に、前記直線移動部の先端側端部を偏らせて配置していることを特徴とする。
In order to solve the above-described problem, an intraocular lens insertion device according to the present disclosure has the following configuration.
(1) By causing a deformable intraocular lens having an optical part and one or a plurality of loop-like support parts extending outward from the periphery of the optical part to advance along a stick-like pushing member along the pushing shaft. An intraocular lens insertion device for insertion into the eye, wherein the intraocular lens pushed out by the push-out member moves linearly in a direction parallel to the push-out axis, and an installation portion in which the intraocular lens is placed in a predetermined direction A linear movement unit that moves the support unit in a direction approaching the optical unit, and the proximal end of the support unit of the intraocular lens that is installed in the installation unit with respect to the push-out shaft is located The front end side end portion of the linear moving portion is biased in the direction .
