The insertion instrument main body 2 includes a main body 10, a top plate portion 30, and a holding member 28 as an example. As an example, the main body 10 includes an insertion portion 20, a placement portion 22, and a holding member 26. The insertion portion 20, the placement portion 22, and the holding member 26 may be integrally formed. Such an intraocular lens insertion device 1 may be an injection molded product using a resin material or the like. The intraocular lens insertion device 1 may be, for example, a cut product by cutting out resin.

本体１０の挿入部２０は、図４の断面において先端２０ａに向かうにつれて内径が徐々に小さくなる通路２０ｂを備える中空の筒形状に形成されており、その先端２０ａに眼内レンズ１００を外部に送出するための切欠き（ベベル）が形成されている。そして、挿入部２０を通過した眼内レンズ１００は、挿入部２０の内壁面２０ｃに沿って小さく折り曲げられて、先端２０ａの切欠きから外部に送出され、眼内に挿入される。 The insertion portion 20 of the main body 10 is formed in a hollow cylindrical shape having a passage 20b whose inner diameter gradually decreases toward the tip 20a in the cross section of FIG. 4, and the intraocular lens 100 is delivered to the tip 20a to the outside. A notch (bevel) is formed. Then, the intraocular lens 100 that has passed through the insertion portion 20 is bent slightly along the inner wall surface 20c of the insertion portion 20, and is sent to the outside through the notch of the distal end 20a and inserted into the eye.

本体１０の載置部２２は、挿入部２０よりも押出部材１２の押し出し方向の上流側（押出軸Ａの先端側）の位置に形成されている。この載置部２２は、押出部材１２による眼内レンズ１００の押し出し開始前において、眼内レンズ１００が配置される空間（隙間）を備える部分である。そして、載置部２２は、載置部本体２４と、保持部材２６と、保持部材２８と、天板部３０などを備えている。このような載置部２２において、押出部材１２により押し出される前の眼内レンズ１００が、載置部本体２４の内部にて、保持部材２６と保持部材２８により保持されつつ配置される。保持部材２６は板形状であり、押出軸Ａの先端側で載置部本体２４に接続されている。保持部材２６と載置部本体２４との接続部は、押出軸Ａと直交する方向に伸びる回動軸となる。保持部材２６は、前述した回動軸によって、載置部本体２４に対して回動可能とされている。また、保持部材２６と載置部本体２４とは嵌合部によって嵌合可能とされている。 The mounting portion 22 of the main body 10 is formed at a position upstream of the insertion portion 20 in the pushing direction of the pushing member 12 (the tip side of the pushing shaft A). The placement portion 22 is a portion having a space (gap) in which the intraocular lens 100 is arranged before the push-out member 12 starts to push out the intraocular lens 100. The placement unit 22 includes a placement unit main body 24, a holding member 26, a holding member 28, a top plate portion 30, and the like. In such a mounting portion 22, the intraocular lens 100 before being pushed out by the push member 12 is disposed inside the mounting portion main body 24 while being held by the holding member 26 and the holding member 28. The holding member 26 has a plate shape and is connected to the mounting portion main body 24 on the distal end side of the extrusion shaft A. A connecting portion between the holding member 26 and the placement portion main body 24 serves as a rotation shaft extending in a direction orthogonal to the extrusion axis A. The holding member 26 can be rotated with respect to the placement portion main body 24 by the above-described rotation shaft. Further, the holding member 26 and the placement portion main body 24 can be fitted by a fitting portion.

天板部３０は、挿入部２０の一部も構成しており、挿入部２０と載置部２２における天側の位置に配置されている蓋部材である。そして、天板部３０は、一例として、図２に示すように、板状部３２、嵌合部３４、および溝３６を備えている。嵌合部３４は、本体１０と嵌合する。本体１０には、嵌合部３４の形状に対応した陥没形状が形成されている。なお、天板部３０を、樹脂材料（例えば、ポリプロピレン）を用いた射出成形品としてもよい。 The top plate portion 30 also constitutes a part of the insertion portion 20 and is a lid member that is disposed at a position on the top side of the insertion portion 20 and the placement portion 22. As an example, the top plate portion 30 includes a plate-like portion 32, a fitting portion 34, and a groove 36 as shown in FIG. The fitting part 34 is fitted with the main body 10. The main body 10 is formed with a depressed shape corresponding to the shape of the fitting portion 34. The top plate 30 may be an injection molded product using a resin material (for example, polypropylene).

溝３６は、板状部３２に形成されており、板状部３２のほぼ中央部から挿入部２０にかけて形成されている。この溝３６は、その軸線が押出部材１２の押し出し方向に形成されており、押出部材１２の押し出し方向を案内する。 The groove 36 is formed in the plate-like portion 32, and is formed from the substantially central portion of the plate-like portion 32 to the insertion portion 20. The groove 36 has an axis formed in the pushing direction of the pushing member 12 and guides the pushing direction of the pushing member 12.

押出部材１２は、眼内レンズ１００の光学部１１０の外周部分を押して挿入部２０内で眼内レンズ１００を小さく折り曲げながら、眼内レンズ１００を挿入部２０の先端２０ａから挿入部２０の外部へ押し出す押出部材である。押出部材１２は、一例として、押圧部５０、軸基部５２、押出棒５４、および先端部５６を備えている。押圧部５０は、眼内レンズ挿入器具１を使用する術者に押圧される部分である。軸基部５２は、押圧部５０に接続される部分である。押出棒５４は、軸基部５２に接続される部分である。先端部５６は、押出棒５４の先端部分に形成される部分である。このような構成の押出部材１２は、本体１０の基端部１０ａから挿入部２０の先端２０ａまで繋がる通路の内部を、押出部材１２の軸方向（押出軸Ａ）に進退可能な状態で、本体１０の内部に挿入されている。 The pushing member 12 pushes the outer peripheral portion of the optical unit 110 of the intraocular lens 100 and bends the intraocular lens 100 in the insertion unit 20 to be bent to the outside of the insertion unit 20 from the distal end 20 a of the insertion unit 20. It is an extrusion member to be extruded. The push member 12 includes, as an example, a pressing portion 50, a shaft base portion 52, a push rod 54, and a tip portion 56. The pressing portion 50 is a portion that is pressed by an operator who uses the intraocular lens insertion device 1. The shaft base portion 52 is a portion connected to the pressing portion 50. The push rod 54 is a portion connected to the shaft base 52. The tip portion 56 is a portion formed at the tip portion of the push rod 54. The pushing member 12 having such a configuration allows the inside of the passage connecting from the base end portion 10a of the main body 10 to the distal end 20a of the insertion portion 20 to move in the axial direction of the pushing member 12 (extrusion axis A). 10 is inserted.

本実施形態の挿入器具本体２は、通過部１１を有している。通過部１１は、眼内レンズ１００が射出される際に、眼内レンズ１００が通過する部位である。通過部１１は、載置部２２の少なくとも一部から先端２０ａにかけて形成されている。載置部２２に載置された眼内レンズ１００は、押出部材１２で押されると、通過部１１を通過して先端２０ａの切欠きから射出される。本実施形態では、通過部１１の少なくとも一部は、天板部３０と本体１０とによって形成されている。 The insertion instrument body 2 of the present embodiment has a passage part 11. The passage part 11 is a part through which the intraocular lens 100 passes when the intraocular lens 100 is emitted. The passage portion 11 is formed from at least a part of the placement portion 22 to the tip 20a. When the intraocular lens 100 placed on the placement part 22 is pushed by the pushing member 12, the intraocular lens 100 passes through the passage part 11 and is ejected from the notch of the tip 20a. In the present embodiment, at least a part of the passage portion 11 is formed by the top plate portion 30 and the main body 10.

次いで、本実施形態で使用される眼内レンズ１００について説明する。本実施形態で使用される眼内レンズ１００は、光学部１１０と、一対の支持部である前方支持部１１２Ａおよび後方支持部１１２Ｂと、が柔軟な素材で一体成形されたワンピースタイプの眼内レンズである。光学部１１０は、円盤形状に形成されている。また、前方支持部１１２Ａと後方支持部１１２Ｂは、光学部１１０の外周部分に接続されている。押出部材１２による眼内レンズ１００の押し出し時において、押出部材１２側に配置される後方支持部１１２Ｂは光学部１１０の外周部分の内側へ曲げられる（折り畳まれる）。 Next, the intraocular lens 100 used in the present embodiment will be described. The intraocular lens 100 used in the present embodiment is a one-piece type intraocular lens in which an optical part 110 and a pair of support parts, a front support part 112A and a rear support part 112B, are integrally formed of a flexible material. It is. The optical unit 110 is formed in a disk shape. Further, the front support portion 112 A and the rear support portion 112 B are connected to the outer peripheral portion of the optical unit 110. When the intraocular lens 100 is pushed out by the push member 12, the rear support portion 112B disposed on the push member 12 side is bent (folded) to the inside of the outer peripheral portion of the optical portion 110.

＜第１実施形態の製造方法＞
次いで、本実施形態の眼内レンズ挿入器具１の、第１実施形態の製造方法を、図５，図９を用いて説明する。図５は、図９で示すフローチャートのステップＳ１０２の工程で、本体１０および天板部３０へ液状物質ＷＨａを付与する状態の一例を説明する説明図である。図９は、眼内レンズ挿入器具１の製造工程のフローチャートである。 <The manufacturing method of 1st Embodiment>
Subsequently, the manufacturing method of 1st Embodiment of the intraocular lens insertion instrument 1 of this embodiment is demonstrated using FIG. 5, FIG. FIG. 5 is an explanatory diagram for explaining an example of a state in which the liquid substance WHa is applied to the main body 10 and the top plate 30 in the step S102 of the flowchart shown in FIG. FIG. 9 is a flowchart of the manufacturing process of the intraocular lens insertion device 1.

先ず、ステップＳ１０１で、作業者は、本体１０と天板部３０とを組み付ける。本実施形態のステップＳ１０１では、作業者は、天板部３０の嵌合部３４と本体１０の図示なき嵌合部とを嵌合させて、本体１０と天板部３０とを組み付ける。ステップＳ１０１で用いる本体１０および天板部３０は、樹脂材料を用いて射出成形されている。 First, in step S 101, the operator assembles the main body 10 and the top plate part 30. In step S 101 of the present embodiment, the operator assembles the main body 10 and the top plate portion 30 by fitting the fitting portion 34 of the top plate portion 30 and a fitting portion (not shown) of the main body 10. The main body 10 and the top plate portion 30 used in step S101 are injection molded using a resin material.

なお、本実施形態のステップＳ１０１〜ステップＳ１０３においては、回動可能な保持部材２６が開いた状態（保持部材２６が載置部本体２４から離れた状態）とされている。また、保持部材２８は本体１０（保持部材２６）に組み付けられておらず、本体１０に眼内レンズ１００は充填されていない。 In step S101 to step S103 of the present embodiment, the rotatable holding member 26 is open (the holding member 26 is separated from the placement portion main body 24). The holding member 28 is not assembled to the main body 10 (holding member 26), and the main body 10 is not filled with the intraocular lens 100.

次いで、ステップＳ１０２において、作業者は、挿入器具本体２へ液状物質ＷＨａの付与を行う（図５参照）。より詳しくは、本実施形態においては、少なくとも、挿入部２０の通路２０ｂ、天板部３０の内面３０ａ、および本体１０と天板部３０との接着部位３９へ液状物質ＷＨａを付与する。換言すると、作業者は、眼内への眼内レンズ１００の挿入時に眼内レンズ１００が通過する通過部１１となる表面の少なくとも一部の箇所と、本体１０と天板部３０とが接着する接着部位３９となる少なくとも一部の箇所とに液状物質ＷＨａを付与する。一例として、本実施形態では、液状物質ＷＨａが充填されたピペット７０１を作業者が操作することで、挿入器具本体２に液状物質ＷＨａが付与される。 Next, in step S102, the operator applies the liquid substance WHa to the insertion instrument body 2 (see FIG. 5). More specifically, in the present embodiment, the liquid substance WHa is applied to at least the passage 20b of the insertion portion 20, the inner surface 30a of the top plate portion 30, and the bonding portion 39 between the main body 10 and the top plate portion 30. In other words, the operator adheres the main body 10 and the top plate part 30 to at least a part of the surface that becomes the passing part 11 through which the intraocular lens 100 passes when the intraocular lens 100 is inserted into the eye. The liquid material WHa is applied to at least a part of the bonding part 39. As an example, in this embodiment, the operator operates the pipette 701 filled with the liquid material WHa, so that the liquid material WHa is applied to the insertion instrument body 2.

水溶性高分子ＷＨとして、液体と溶解した状態で、滑動性が得られる材料を選択することが好ましい。水溶性高分子ＷＨとして、例えば、ポリエチレングリコール、ポリプロピレングリコール、ポリアクリル酸ナトリウム、ポリアクリルアミド、ポリスチレンスルホン酸ナトリウム、ＰＶＰ（ポリビニルピロリドン）、ＭＰＣ（２−メタクリロイルオキシエチルホスホリルコリン）、ポリビニルアルコール、ポリエチレンイミン、カルボキシメチルセルロース、デキストラン硫酸ナトリウム、ポリリン酸、酸化ポリエチレン、酸化ポリプロピレン、ヒアルロン酸ナトリウム等の多糖類、ヒドロキシメチルセルロース、ヒドロキシプロピルメチルセルロース、ポリペプチドを使用してもよい。 As the water-soluble polymer WH, it is preferable to select a material that can provide slidability in a dissolved state with a liquid. Examples of the water-soluble polymer WH include polyethylene glycol, polypropylene glycol, sodium polyacrylate, polyacrylamide, sodium polystyrene sulfonate, PVP (polyvinylpyrrolidone), MPC (2-methacryloyloxyethyl phosphorylcholine), polyvinyl alcohol, polyethyleneimine, Polysaccharides such as carboxymethylcellulose, sodium dextran sulfate, polyphosphoric acid, oxidized polyethylene, oxidized polypropylene, sodium hyaluronate, hydroxymethylcellulose, hydroxypropylmethylcellulose, and polypeptide may be used.

本実施形態においては、水溶性高分子ＷＨとして、ヒアルロン酸ナトリウムを用いている。また、真水（液体）にヒアルロン酸ナトリウム（水溶性高分子ＷＨ）が溶解されることで液状物質ＷＨａとされている。本実施形態においては、一例として、液状物質ＷＨａの重量に含まれるヒアルロン酸ナトリウムの重量が０．２５％とされている。水溶性高分子ＷＨとして、液体と溶解した状態で滑動性が得られると共に、溶媒が乾燥することで接着性を発揮する材料が選択される。さらに、本実施形態で用いられる水溶性高分子ＷＨは、生体内（本実施形態では眼内）に混入しても生体に無害なものが選択される。液状物質ＷＨａに含まれる水溶性高分子ＷＨの割合はこれに限るものでない。水溶性高分子ＷＨで部材同士を接着できればよい。また、隙間Ｕａへ液状物質ＷＨａが入り込めばよい。ステップＳ１０２の作業を行う前に、挿入部２０の内壁面２０ｃと内面３０ａとの少なくともいずれかの表面状態を粗く加工してもよい。例えば、挿入部２０の内壁面２０ｃと内面３０ａとの少なくともいずれかの表面を、周知のプラズマ処理を用いて加工してもよい。表面状態を粗く加工することで、挿入部２０または天板部３０へ、より好適に水溶性高分子ＷＨを付与できる。 In this embodiment, sodium hyaluronate is used as the water-soluble polymer WH. Further, the liquid substance WHa is obtained by dissolving sodium hyaluronate (water-soluble polymer WH) in fresh water (liquid). In the present embodiment, as an example, the weight of sodium hyaluronate contained in the weight of the liquid material WHa is 0.25%. As the water-soluble polymer WH, a material that can be slidable in a dissolved state with a liquid and that exhibits adhesiveness when the solvent is dried is selected. Furthermore, the water-soluble polymer WH used in the present embodiment is selected so as to be harmless to the living body even if mixed in the living body (in this embodiment, the eye). The ratio of the water-soluble polymer WH contained in the liquid material WHa is not limited to this. It is only necessary that the members can be bonded with the water-soluble polymer WH. Further, the liquid material WHa may enter the gap Ua. Before performing the operation of step S102, the surface state of at least one of the inner wall surface 20c and the inner surface 30a of the insertion portion 20 may be roughened. For example, at least one of the inner wall surface 20c and the inner surface 30a of the insertion portion 20 may be processed using a known plasma process. By processing the surface state roughly, the water-soluble polymer WH can be more suitably imparted to the insertion portion 20 or the top plate portion 30.

作業者は、図５で示すように、天板部３０の外面３０ｂが下方を向くように本体１０を支持する。本体１０を支持するために、作業机、または支持工具を用いてもよい。作業者は、保持部材２６を開くと形成される本体１０の開口部へ、液状物質ＷＨａが充填されたピペット７０１の先端を挿入する。作業者は、ピペット７０１の先端から液状物質ＷＨａを流出させて、挿入器具本体２への液状物質ＷＨａの付与を行う。より詳しくは、挿入部２０の通路２０ｂ、天板部３０の内面３０ａ、および本体１０と天板部３０との接着部位３９へ、液状物質ＷＨａを付与する。液状物質ＷＨａを付与した後、作業者は、天板部３０の外面３０ｂが下方を向くように挿入器具本体２の方向を維持したまま恒温槽へ入れる。恒温槽で、液状物質ＷＨａが付与された挿入器具本体２に対して、加温加湿の処理が所定時間行われる。 As shown in FIG. 5, the worker supports the main body 10 so that the outer surface 30 b of the top plate portion 30 faces downward. In order to support the main body 10, a work desk or a support tool may be used. The operator inserts the tip of the pipette 701 filled with the liquid substance WHa into the opening of the main body 10 formed when the holding member 26 is opened. The operator causes the liquid substance WHa to flow out from the tip of the pipette 701 and applies the liquid substance WHa to the insertion instrument body 2. More specifically, the liquid substance WHa is applied to the passage 20 b of the insertion portion 20, the inner surface 30 a of the top plate portion 30, and the adhesion portion 39 between the main body 10 and the top plate portion 30. After giving the liquid substance WHa, the operator puts the insertion instrument body 2 in the thermostatic chamber while maintaining the direction of the insertion instrument body 2 so that the outer surface 30b of the top plate portion 30 faces downward. In the thermostat, the heating and humidification process is performed for a predetermined time on the insertion instrument body 2 to which the liquid substance WHa is applied.

図６は、図５のＩＩＩ−ＩＩＩ断面の部分断面図である。本実施形態の挿入器具本体２は、天板部３０と本体１０（載置部本体２４）とが前述した嵌合部３４で嵌合されており、天板部３０と本体１０との間に幅ＰＡで離間した隙間Ｕａが形成されている。作業者によって接着部位３９の近傍へ付与された液状物質ＷＨａは、毛細管現象によって隙間Ｕａへ流れ込む。つまり、天板部３０と本体１０との間に液状物質ＷＨａが介在される。隙間Ｕａは、天板部３０と本体１０とを接着する際の、接着部位３９の少なくとも一部となる。なお、内側（紙面上方）にて天板部３０と本体１０とをまたぐ液状物質ＷＨａも、天板部３０と本体１０とを接着させる作用があるため、接着部位３９の少なくとも一部となる。なお、本実施形態においては、離間距離が０．０５ｍｍ以上かつ０．２ｍｍ以下となる隙間Ｕａを設けている。 6 is a partial cross-sectional view taken along the line III-III in FIG. In the insertion instrument main body 2 of the present embodiment, the top plate portion 30 and the main body 10 (mounting portion main body 24) are fitted in the fitting portion 34 described above, and the top plate portion 30 and the main body 10 are interposed between them. A gap Ua separated by a width PA is formed. The liquid material WHa applied to the vicinity of the adhesion site 39 by the operator flows into the gap Ua by a capillary phenomenon. That is, the liquid material WHa is interposed between the top plate portion 30 and the main body 10. The gap Ua becomes at least a part of the bonding portion 39 when the top plate portion 30 and the main body 10 are bonded. Note that the liquid substance WHa straddling the top plate 30 and the main body 10 on the inner side (above the paper surface) also has an action of bonding the top plate 30 and the main body 10, and thus becomes at least a part of the bonding portion 39. In the present embodiment, a gap Ua is provided in which the separation distance is 0.05 mm or more and 0.2 mm or less.

接着部位３９の構造はこれに限るものではない。例えば、図７で例示する構造としてもよい。図７の接着部位３９の構造は、図６で示した隙間Ｕａの形状を変更したものである。より詳しくは、内面側は、図６の隙間Ｕａよりも間隔を広げた隙間Ｕｂが形成されている。隙間Ｕｂに接続され、隙間Ｕｂよりも外側に配置される隙間Ｕｃは、隙間Ｕｂよりも間隔を狭めた隙間が設けられている。隙間Ｕｂは、図６の隙間Ｕａと同じ間隔（距離ＰＡ）の隙間が形成されている。隙間Ｕｃに接続され、隙間Ｕｃよりも外側に配置される隙間Ｕｄは、隙間Ｕｃよりも間隔を狭めた隙間で形成されている。 The structure of the adhesion part 39 is not restricted to this. For example, the structure illustrated in FIG. 7 may be used. The structure of the adhesion part 39 in FIG. 7 is obtained by changing the shape of the gap Ua shown in FIG. More specifically, a gap Ub that is wider than the gap Ua in FIG. 6 is formed on the inner surface side. The gap Uc connected to the gap Ub and disposed outside the gap Ub is provided with a gap that is narrower than the gap Ub. The gap Ub has the same gap (distance PA) as the gap Ua in FIG. The gap Ud that is connected to the gap Uc and arranged outside the gap Uc is formed as a gap that is narrower than the gap Uc.

図７の隙間Ｕの形状とした場合には、図６の隙間Ｕの形状とした場合よりも、天板部３０と本体１０との間の隙間に介在する液状物質ＷＨａの量が増えると考えられる。また、外側では、図６の隙間Ｕの形状よりも、天板部３０と本体１０との間の隙間に介在する液状物質ＷＨａの量が減ると考えられる。したがって、隙間Ｕを介して外側から漏れ出る液状物質ＷＨａの液量を、好適に抑制できると考えられる。なお、図６および図７で示した隙間Ｕ（隙間Ｕａ〜Ｕｄ）の形状、および液状物質ＷＨａの付与状態は一例であり、これに限るものではない。また、本実施形態においては、天板部３０と本体１０とを嵌合部３４を用いて嵌合させた後、挿入器具本体２へ液状物質ＷＨａを付与しているが、これに限るものではない。例えば、眼内レンズ挿入器具１が嵌合部３４を備えない態様としてもよい。かかる態様においては、天板部３０と本体１０との位置関係を固定する工具７０３を用いて天板部３０と本体１０とを組み立てた後に、挿入器具本体２へ液状物質ＷＨａを付与してもよい（図１２参照）。 When the shape of the gap U in FIG. 7 is used, it is considered that the amount of the liquid substance WHa interposed in the gap between the top plate 30 and the main body 10 is larger than in the case of the shape of the gap U in FIG. It is done. Further, on the outside, it is considered that the amount of the liquid material WHa interposed in the gap between the top plate portion 30 and the main body 10 is smaller than the shape of the gap U in FIG. Therefore, it is considered that the amount of the liquid substance WHa leaking from the outside through the gap U can be suitably suppressed. The shape of the gap U (gap Ua to Ud) and the application state of the liquid substance WHa shown in FIGS. 6 and 7 are examples, and the present invention is not limited to this. Further, in the present embodiment, the liquid material WHa is given to the insertion instrument body 2 after the top plate part 30 and the main body 10 are fitted using the fitting part 34. However, the present invention is not limited to this. Absent. For example, the intraocular lens insertion device 1 may not include the fitting portion 34. In such an embodiment, the liquid material WHa is applied to the insertion instrument body 2 after assembling the top panel 30 and the main body 10 using the tool 703 that fixes the positional relationship between the top panel 30 and the main body 10. Good (see FIG. 12).

次いでステップＳ１０３で、作業者は、恒温槽から挿入器具本体２を取り出して、挿入器具本体２の乾燥を行う。本実施形態の挿入器具本体２の乾燥は、先端２０ａを下方へ向けた状態で、所定時間、自然乾燥させる。なお、恒温オーブンに入れて挿入器具本体２を乾燥させてもよい。また、上方または水平方向へ先端２０ａを向けて、挿入器具本体２を乾燥させてもよい。なお、ステップＳ１０３における乾燥とは、液状物質ＷＨａを構成するする液状物質のうち、水溶性高分子ＷＨを溶融させている溶媒（本実施形態では水）を蒸発させる作業としている。乾燥が行われると、挿入器具本体２は、眼内レンズ１００の挿入時に眼内レンズ１００が通過する通過部１１の表面の少なくとも一部と、本体１０と天板部３０とが接着する接着部位３９の少なくとも一部とに、乾燥状態（固体）の水溶性高分子ＷＨが付与された状態となる。つまり、乾燥状態の水溶性高分子ＷＨによって、本体１０と天板部３０とが接着された状態となる。なお、「乾燥状態」とは、溶媒が完全に乾燥した状態に限定されることは無い。つまり、水溶性高分子ＷＨが接着性を発揮する程度に溶媒が乾燥していればよい。 Next, in step S103, the operator takes out the insertion instrument body 2 from the thermostat and dries the insertion instrument body 2. The insertion instrument main body 2 according to the present embodiment is naturally dried for a predetermined time with the tip 20a facing downward. Note that the insertion instrument body 2 may be dried in a constant temperature oven. Alternatively, the insertion instrument body 2 may be dried with the tip 20a facing upward or horizontally. The drying in step S103 is an operation of evaporating a solvent (water in this embodiment) in which the water-soluble polymer WH is melted out of the liquid material constituting the liquid material WHa. When drying is performed, the insertion instrument main body 2 is bonded to at least a part of the surface of the passage portion 11 through which the intraocular lens 100 passes when the intraocular lens 100 is inserted, and the main body 10 and the top plate 30 are bonded to each other. At least a part of 39 is in a state where a dry (solid) water-soluble polymer WH is applied. That is, the main body 10 and the top plate part 30 are bonded to each other by the dry water-soluble polymer WH. The “dried state” is not limited to a state in which the solvent is completely dried. That is, it is sufficient that the solvent is dried to such an extent that the water-soluble polymer WH exhibits adhesiveness.

以上説明したステップＳ１０１〜ステップＳ１０３の製造工程によって、挿入器具本体２への水溶性高分子ＷＨの付与が完了する。その後、開かれている保持部材２６へ眼内レンズ１００を装着する作業、続けて、保持部材２６を回動して閉じる作業、続けて、保持部材２６へ保持部材２８を装着する作業、続けて、挿入器具本体２への押出部材１２を装着する作業、等を経て、眼内レンズ挿入器具１（眼内レンズ挿入システム）の組み立てが完了される。 The application of the water-soluble polymer WH to the insertion instrument main body 2 is completed by the manufacturing process of steps S101 to S103 described above. Thereafter, the operation of attaching the intraocular lens 100 to the holding member 26 that is opened, the operation of rotating and closing the holding member 26, the operation of attaching the holding member 28 to the holding member 26, and the like. The assembly of the intraocular lens insertion instrument 1 (intraocular lens insertion system) is completed through the operation of attaching the push member 12 to the insertion instrument body 2 and the like.

組み立てられた眼内レンズ挿入器具１は、輸送用の密閉容器へ入れられた後に滅菌処理される。使用現場では、術者が密閉容器から眼内レンズ挿入器具１を取り出し、天板部３０に設けられている注入口から液状の滑動剤を挿入器具本体２の内部へ注入する。術者は、挿入器具本体２の内部へ滑動剤を注入した後に、押出部材１２を押して眼内レンズ１００を射出する。挿入器具本体２の内部へ液状の滑動剤が注入されることで、通過部１１へ付与されている乾燥状態の水溶性高分子ＷＨの少なくとも一部は、液状の滑動剤に溶解される。押出部材１２で押される眼内レンズ１００が通過部１１を形成する内壁（例えば、内壁面２０ｃおよび内面３０ａ）と接した場合であっても、溶解された水溶性高分子ＷＨによって接触抵抗が低減される。したがって、先端２０ａの開口部から眼内レンズ１００が好適に射出される。 The assembled intraocular lens insertion device 1 is sterilized after being placed in a sealed container for transportation. At the site of use, the surgeon takes out the intraocular lens insertion device 1 from the sealed container and injects a liquid lubricant into the insertion device main body 2 from the injection port provided in the top plate 30. The surgeon injects the lubricant into the insertion instrument body 2 and then pushes the pusher member 12 to eject the intraocular lens 100. By injecting the liquid lubricant into the insertion instrument main body 2, at least a part of the water-soluble polymer WH in the dry state applied to the passage portion 11 is dissolved in the liquid lubricant. Even when the intraocular lens 100 pushed by the pushing member 12 is in contact with the inner wall (for example, the inner wall surface 20c and the inner surface 30a) forming the passage portion 11, the contact resistance is reduced by the dissolved water-soluble polymer WH. Is done. Therefore, the intraocular lens 100 is suitably emitted from the opening of the tip 20a.

＜第２実施形態の製造方法＞
次いで、図８，図１０を用いて、第２実施形態の製造方法を説明する。図８は、第２実施形態の製造作業を説明する説明図である。図１０は、第２実施形態の製造工程のフローチャートである。 <Manufacturing Method of Second Embodiment>
Next, the manufacturing method of the second embodiment will be described with reference to FIGS. FIG. 8 is an explanatory diagram for explaining the manufacturing operation of the second embodiment. FIG. 10 is a flowchart of the manufacturing process of the second embodiment.

先ず、ステップＳ２０１で、作業者は、本体１０へ液状物質ＷＨａを付与する。より詳しくは、図８（ａ）で示すように、液状物質ＷＨａが充填されたピペット７０１の先端を、挿入部２０の内部空間まで挿入し、挿入部２０の内部空間へ液状物質ＷＨａを充填する。第１実施形態の製造方法と同様に、液状物質ＷＨａには水溶性高分子ＷＨが溶解している。 First, in step S 201, the operator applies the liquid material WHa to the main body 10. More specifically, as shown in FIG. 8A, the tip of the pipette 701 filled with the liquid material WHa is inserted into the internal space of the insertion portion 20, and the liquid space WHa is filled into the internal space of the insertion portion 20. . Similar to the manufacturing method of the first embodiment, the water-soluble polymer WH is dissolved in the liquid material WHa.

次いで、ステップＳ２０２において、作業者は、天板部３０への液状物質ＷＨａを付与する。より詳しくは、図８（ｂ）で示すように、ビーカー７０２へ注入されている液状物質ＷＨａの液中に、天板部３０を挿入する。天板部３０を図示なき工具で把持して液状物質ＷＨａの液中に挿入する。天板部３０は、所定時間、液状物質ＷＨａの液中に挿入される。 Next, in step S202, the operator applies the liquid material WHa to the top plate 30. More specifically, as shown in FIG. 8B, the top plate portion 30 is inserted into the liquid material WHa injected into the beaker 702. The top plate 30 is held by a tool (not shown) and inserted into the liquid material WHa. The top plate 30 is inserted into the liquid material WHa for a predetermined time.

次いで、ステップＳ２０３において、作業者は、ステップＳ２０１で液状物質ＷＨａを付与した本体１０と、ステップＳ２０２で液状物質ＷＨａを付与した天板部３０とを組み付ける（図８（ｃ）参照）。なお、ステップＳ２０３で組み付ける本体１０と天板部３０とは、ステップＳ２０３より前に付与された液状物質ＷＨａが乾燥しない状態で組み付けられる。本体１０と天板部３０とが組み立てられた挿入器具本体２を、恒温槽へ入れる。恒温槽で、付与された液状物質ＷＨａが乾燥する前の挿入器具本体２に対して、加温加湿の処理を所定時間行う。 Next, in step S203, the operator assembles the main body 10 provided with the liquid material WHa in step S201 and the top plate portion 30 provided with the liquid material WHa in step S202 (see FIG. 8C). In addition, the main body 10 and the top plate part 30 assembled in step S203 are assembled in a state where the liquid material WHa applied before step S203 is not dried. The insertion instrument main body 2 in which the main body 10 and the top plate portion 30 are assembled is put into a thermostatic bath. In the thermostatic bath, a heating and humidification process is performed for a predetermined time on the insertion instrument body 2 before the applied liquid substance WHa is dried.

次いで、ステップＳ２０４において、作業者は、恒温槽から挿入器具本体２を取り出して、挿入器具本体２の乾燥を行う。以上のステップＳ２０１〜ステップＳ２０３の工程によって挿入器具本体２への水溶性高分子ＷＨの付与が完了する。ステップＳ２０４の乾燥作業は、第１実施形態のステップＳ１０３と同様であり、ステップＳ２０４より後の作業は、第１実施形態のステップＳ１０３より後の作業と同様であるため、説明を省略する。なお、上記で例示した第２実施形態では、本体１０と天板部３０（つまり、接着される２つの部材の両方）に液状物質ＷＨａが付与された後、両者が組み付けられる。従って、両者の接着の確実性が向上する。しかし、２つの部材の一方にのみ液状物質ＷＨａを付与することも可能である（以下説明する第３実施形態でも同様）。 Next, in step S204, the operator takes out the insertion instrument body 2 from the thermostat and dries the insertion instrument body 2. The application of the water-soluble polymer WH to the insertion instrument body 2 is completed by the steps S201 to S203. The drying operation in step S204 is the same as step S103 in the first embodiment, and the operation after step S204 is the same as the operation after step S103 in the first embodiment, and thus description thereof is omitted. In the second embodiment illustrated above, after the liquid material WHa is applied to the main body 10 and the top plate portion 30 (that is, both of the two members to be bonded), both are assembled. Therefore, the certainty of adhesion of both is improved. However, it is also possible to apply the liquid substance WHa to only one of the two members (the same applies to the third embodiment described below).

＜第３実施形態の製造方法＞
次いで、図１１を用いて、第３実施形態の製造方法を説明する。図１１は、第３実施形態の製造工程のフローチャートである。 <Manufacturing Method of Third Embodiment>
Next, the manufacturing method of the third embodiment will be described with reference to FIG. FIG. 11 is a flowchart of the manufacturing process of the third embodiment.

先ず、ステップＳ３０１で作業者は、本体１０へ液状物質ＷＨａを付与する。次いで、ステップＳ３０２で、作業者は、天板部３０への液状物質ＷＨａを付与する。ステップＳ３０１，ステップＳ３０２の作業は、先に第２実施形態の製造方法として説明したステップＳ２０１およびステップＳ２０２と同様であるため、詳細説明を省略する。 First, in step S 301, the worker applies the liquid substance WHa to the main body 10. Next, in step S302, the operator applies the liquid material WHa to the top plate 30. Since the operations of Step S301 and Step S302 are the same as Step S201 and Step S202 described above as the manufacturing method of the second embodiment, detailed description thereof is omitted.

次いで、ステップＳ３０３およびステップＳ３０４において、作業者は、先のステップＳ３０１およびステップＳ３０２で付与した液状物質ＷＨａを乾燥させる（つまり、液状物質ＷＨａ中の溶媒を乾燥させる）。 Next, in step S303 and step S304, the operator dries the liquid material WHa applied in the previous steps S301 and S302 (that is, the solvent in the liquid material WHa is dried).

次いで、ステップＳ３０５において、作業者は、本体１０と天板部３０とを組み付ける。次いで、ステップＳ３０６において、作業者は、本体１０と天板部３０とが組み立てられた挿入器具本体２に対して、加湿の処理を行う。本実施形態の加湿の処理には、一例として恒温槽が用いられる。かかる加湿の処理によって、接着部位３９に付与された乾燥状態の水溶性高分子ＷＨは、加湿として付与される液体と結合する。加湿の処理によって、本体１０と天板部３０との接着部位３９の少なくとも一部となる隙間Ｕに、非乾燥状態の水溶性高分子ＷＨが介在する状態になる。その結果、本体１０と天板部３０とが接着される。加湿の処理は、所定時間行われる。 Next, in step S 305, the operator assembles the main body 10 and the top plate part 30. Next, in step S306, the operator performs a humidification process on the insertion instrument main body 2 in which the main body 10 and the top plate portion 30 are assembled. A constant temperature bath is used as an example for the humidification process of the present embodiment. By the humidification process, the water-soluble polymer WH in a dry state applied to the adhesion site 39 is combined with a liquid applied as humidification. By the humidification process, the water-soluble polymer WH in a non-dry state is interposed in the gap U that becomes at least a part of the adhesion portion 39 between the main body 10 and the top plate portion 30. As a result, the main body 10 and the top plate portion 30 are bonded. The humidification process is performed for a predetermined time.

次いで、ステップＳ３０７において、作業者は、恒温槽から挿入器具本体２を取り出して、挿入器具本体２の乾燥を行う。以上のステップＳ３０１〜ステップＳ３０７の工程によって挿入器具本体２への水溶性高分子ＷＨの付与が完了する。なお、ステップＳ３０７の乾燥作業は、第１実施形態のステップＳ１０３と同様であり、ステップＳ３０７より後の作業は、第１実施形態のステップＳ１０３より後の作業と同様であるため、説明を省略する。 Next, in step S307, the operator takes out the insertion instrument body 2 from the thermostat and dries the insertion instrument body 2. The application of the water-soluble polymer WH to the insertion instrument body 2 is completed by the steps S301 to S307. Note that the drying operation in step S307 is the same as step S103 in the first embodiment, and the operation after step S307 is the same as the operation after step S103 in the first embodiment, and thus description thereof is omitted. .

＜作用及び効果＞
本実施形態の眼内レンズ挿入器具１は、少なくとも第１部材（例えば天板部３０）と第２部材（例えば本体１０）とが接着されることで形成され、眼内への眼内レンズ１００の挿入時に眼内レンズ１００が通過する通過部１１を内部に有する挿入器具本体２と、液体に溶解することで、通過部１１の表面（例えば内壁面２０ｃ，内面３０ａ）と眼内レンズ１００との間に生じる摩擦力を低下させる水溶性高分子ＷＨとを備えており、第１部材（例えば天板部３０）と第２部材（例えば本体１０）とが接着する接着部位３９の少なくとも一部に付与された、乾燥状態の水溶性高分子ＷＨによって、第１部材（例えば天板部３０）と第２部材（例えば本体１０）とが接着されている。 <Action and effect>
The intraocular lens insertion device 1 of the present embodiment is formed by adhering at least a first member (for example, the top plate portion 30) and a second member (for example, the main body 10), and the intraocular lens 100 into the eye. The insertion instrument main body 2 having a passage portion 11 through which the intraocular lens 100 passes when inserted, and the surface of the passage portion 11 (for example, the inner wall surface 20c and the inner surface 30a) and the intraocular lens 100 by dissolving in the liquid. And a water-soluble polymer WH that reduces a frictional force generated between the first member (for example, the top plate 30) and the second member (for example, the main body 10). The first member (for example, the top plate portion 30) and the second member (for example, the main body 10) are bonded to each other by the water-soluble polymer WH in a dry state, which is applied to.

かかる態様とすることで、例えば、部材同士を接続するための嵌合構造（嵌合部３４）が不要になり、眼内レンズ挿入器具１の構成を簡素化できる。また、例えば、部材同士を接続するための嵌合構造（嵌合部３４）を簡素化できるため、眼内レンズ挿入器具１の大型化を抑制できる。また、使用時に、眼内レンズ挿入器具１へ流入される液体で、接着部位３９へ付与されている固体状態の水溶性高分子ＷＨの少なくとも一部が溶解した場合であっても、溶解された水溶性高分子ＷＨは、眼内レンズ１００の好適な射出に寄与できるとものと考えられる。 By setting it as this aspect, the fitting structure (fitting part 34) for connecting members for example becomes unnecessary, and the structure of the intraocular lens insertion instrument 1 can be simplified. For example, since the fitting structure (fitting part 34) for connecting members can be simplified, the enlargement of the intraocular lens insertion device 1 can be suppressed. In addition, the liquid that flows into the intraocular lens insertion device 1 during use was dissolved even when at least a part of the solid-state water-soluble polymer WH applied to the adhesion site 39 was dissolved. It is considered that the water-soluble polymer WH can contribute to suitable injection of the intraocular lens 100.

また、液体に溶解することで、部材同士間の摩擦力を低下させる水溶性高分子ＷＨは、眼内レンズ、もしくは眼内レンズ挿入器具の製造現場で他の目的として用いられる可能性も考えられる。例えば、眼内レンズ挿入器具の種類に応じて、眼内レンズ挿入器具１に付与する水溶性高分子を異ならせる場合も考えられる。液体に溶解することで部材同士間の摩擦力を低下させる水溶性高分子ＷＨを部材同士の接着に用いることで、眼内レンズ挿入器具１の製造に使用する部材の種類の増加を抑制でき、眼内レンズ挿入器具１を製造する際の部材の管理が容易になる。例えば、通過部１１の表面へ付着させる水溶性高分子ＷＨと部品同士を接着させる水溶性高分子ＷＨとを異なる種類の水溶性高分子ＷＨとしてもよい。液体に溶解することで、部材同士間の摩擦力を低下させる複数種類の水溶性高分子ＷＨを、眼内レンズ挿入器具１の異なる箇所へ種類を使い分けて付与する（付与する箇所に応じて好適な水溶性高分子ＷＨを選択して付与する）ことで、眼内レンズ、もしくは眼内レンズ挿入器具の製造現場で用いる（管理する）水溶性高分子ＷＨの種類の増加を抑制できる。 In addition, the water-soluble polymer WH that reduces the frictional force between members by dissolving in a liquid may be used for other purposes at the manufacturing site of an intraocular lens or an intraocular lens insertion device. . For example, the case where the water-soluble polymer provided to the intraocular lens insertion device 1 is changed depending on the type of the intraocular lens insertion device may be considered. By using a water-soluble polymer WH that reduces the frictional force between members by dissolving in a liquid for adhesion between members, an increase in the types of members used for manufacturing the intraocular lens insertion device 1 can be suppressed, Management of members when manufacturing the intraocular lens insertion device 1 is facilitated. For example, the water-soluble polymer WH that adheres to the surface of the passage portion 11 and the water-soluble polymer WH that adheres components may be different types of water-soluble polymer WH. By dissolving in a liquid, a plurality of types of water-soluble polymers WH that reduce the frictional force between members are applied to different locations of the intraocular lens insertion device 1 by using different types (suitable according to the location to be applied) By selecting and applying a water-soluble polymer WH which is a suitable water-soluble polymer), it is possible to suppress an increase in the type of water-soluble polymer WH used (managed) at the manufacturing site of an intraocular lens or an intraocular lens insertion device.

本実施形態の眼内レンズ挿入器具１は、通過部１１の表面（例えば内壁面２０ｃ，内面３０ａ）の少なくとも一部に水溶性高分子ＷＨが付着されている。 In the intraocular lens insertion device 1 of the present embodiment, the water-soluble polymer WH is attached to at least a part of the surface of the passage portion 11 (for example, the inner wall surface 20c and the inner surface 30a).

かかる態様とすることで、眼内レンズ１００は、より好適に通過部１１を通過できる。眼内レンズ挿入器具１の構成を簡素化できる。また、通過部１１の表面と眼内レンズ１００との間に生じる摩擦力を低下させるための材料と、接着に用いるための材料とを同一の材料としているため、眼内レンズ挿入器具１を製造する際の部材の管理が容易になる。例えば、眼内レンズ挿入器具１を安価に製造でき、眼内レンズ挿入器具１を安価に提供できる。 By setting it as this aspect, the intraocular lens 100 can pass the passage part 11 more suitably. The configuration of the intraocular lens insertion device 1 can be simplified. In addition, since the material for reducing the frictional force generated between the surface of the passage portion 11 and the intraocular lens 100 and the material used for bonding are the same material, the intraocular lens insertion device 1 is manufactured. Management of the member at the time becomes easy. For example, the intraocular lens insertion device 1 can be manufactured at low cost, and the intraocular lens insertion device 1 can be provided at low cost.

また、本実施形態の眼内レンズ挿入器具１は、第１部材（例えば天板部３０）と第２部材（例えば本体１０）とが接着する接着部位３９の少なくとも一部に、水溶性高分子ＷＨが溶解された液状物質ＷＨａが入り込む隙間Ｕ（隙間Ｕａ，隙間Ｕｂ）が形成されており、乾燥状態の水溶性高分子ＷＨは、隙間Ｕに入り込んで第１部材（例えば天板部３０）と第２部材（例えば本体１０）とを接着している。 In addition, the intraocular lens insertion device 1 of the present embodiment has a water-soluble polymer on at least a part of the bonding portion 39 where the first member (for example, the top plate portion 30) and the second member (for example, the main body 10) are bonded. A gap U (gap Ua, gap Ub) into which the liquid substance WHa in which WH is dissolved is formed, and the water-soluble polymer WH in the dry state enters the gap U and enters the first member (for example, the top plate 30). And the second member (for example, the main body 10) are bonded.

かかる態様とすることで、通過部１１の表面へ付与する水溶性高分子ＷＨによって第１部材（例えば天板部３０）と第２部材（例えば本体１０）とを好適に接着できる。例えば、通過部１１の表面だけでなく、通過部１１を形成する部材の内部（深部）でも第１部材（例えば天板部３０）と第２部材（例えば本体１０）とが水溶性高分子ＷＨで接着される。第１部材（例えば天板部３０）と第２部材（例えば本体１０）との接着に隙間Ｕを用いることで、第１部材（例えば天板部３０）と第２部材（例えば本体１０）とを通過部１１の表面のみで接着する場合に対して強固に接着できる。 By setting it as this aspect, the 1st member (for example, top-plate part 30) and the 2nd member (for example, main body 10) can be adhere | attached suitably with the water-soluble polymer WH provided to the surface of the passage part 11. FIG. For example, the first member (for example, the top plate portion 30) and the second member (for example, the main body 10) are not limited to the surface of the passing portion 11 but also within the member forming the passing portion 11 (in the deep portion). Glued with. By using the gap U for bonding between the first member (for example, the top plate portion 30) and the second member (for example, the main body 10), the first member (for example, the top plate portion 30) and the second member (for example, the main body 10) Can be firmly adhered to the case of adhering only on the surface of the passage portion 11.

また、本実施形態の眼内レンズ挿入器具１は、水溶性高分子ＷＨが溶解された液状物質ＷＨａが毛細管現象によって入り込む間隔で隙間Ｕ（隙間Ｕａ，隙間Ｕｂ）が形成されている。 Further, in the intraocular lens insertion device 1 of the present embodiment, gaps U (gap Ua, gap Ub) are formed at intervals at which the liquid substance WHa in which the water-soluble polymer WH is dissolved enters by capillary action.

かかる態様とすることで、水溶性高分子ＷＨが溶解された液状物質ＷＨａを接着部位３９へ好適に付与できる。例えば、眼内レンズ挿入器具１の製造時に、複雑な作業を要することなく接着部位３９へ水溶性高分子ＷＨを付与できる。また、例えば、毛細管現象を用いることで、液状物質ＷＨａを流し込むために形成される通過部１１の陥没形状または間隙形状の大きさを抑制できる。眼内レンズ１００が通過部１１を移動する際に、部品同士の接着に用いる陥没形状または間隙形状の箇所で引っ掛かる事象を抑制できる。 By setting it as this aspect, the liquid substance WHa in which the water-soluble polymer WH is dissolved can be suitably applied to the adhesion site 39. For example, when manufacturing the intraocular lens insertion device 1, the water-soluble polymer WH can be applied to the adhesion site 39 without requiring a complicated operation. In addition, for example, by using a capillary phenomenon, the size of the depression shape or the gap shape of the passage portion 11 formed for pouring the liquid substance WHa can be suppressed. When the intraocular lens 100 moves through the passage portion 11, it is possible to suppress an event of being caught at a depressed shape or a gap-shaped portion used for bonding parts.

また、本実施形態の眼内レンズ挿入器具１は、第１部材（例えば天板部３０）と第２部材（例えば本体１０）とを嵌合するための嵌合部３４を有しており、第１部材（例えば天板部３０）と第２部材（例えば本体１０）とが嵌合部３４で嵌合した状態で、第１部材（例えば天板部３０）と第２部材（例えば本体１０）とが水溶性高分子ＷＨで接着されている。 Further, the intraocular lens insertion device 1 of the present embodiment has a fitting portion 34 for fitting a first member (for example, the top plate portion 30) and a second member (for example, the main body 10), In a state in which the first member (for example, the top plate portion 30) and the second member (for example, the main body 10) are fitted by the fitting portion 34, the first member (for example, the top plate portion 30) and the second member (for example, the main body 10). And a water-soluble polymer WH.

かかる態様とすることで、水溶性高分子ＷＨによる接着力に加えて、嵌合部３４による嵌合力を用いて第１部材（例えば天板部３０）と第２部材（例えば本体１０）とを接続できる。例えば、眼内レンズ挿入器具１の製造時に、複雑な組立設備を要することなく第１部材（例えば天板部３０）と第２部材（例えば本体１０）とを好適な接続力で接続できる。例えば、嵌合部３４の嵌合力みで第１部材（例えば天板部３０）と第２部材（例えば本体１０）とを接続する場合に対して、嵌合部３４の大きさおよび数の少なくともいずれかを減少させることが容易になるので、眼内レンズ挿入器具１を小型化できる。眼内レンズ挿入器具１の取り扱いが容易になる。 By setting it as this aspect, in addition to the adhesive force by water-soluble polymer WH, using the fitting force by the fitting part 34, a 1st member (for example, top-plate part 30) and a 2nd member (for example, main body 10) are made.
