眼内レンズ挿入器具の挿入練習用キットIntraocular lens insertion instrument insertion practice kit
　本発明は、眼内レンズ挿入器具の挿入練習用キット（以下、練習用キットと略す）に関する。 The present invention relates to an insertion practice kit for an intraocular lens insertion instrument (hereinafter abbreviated as a practice kit).
　白内障治療においてヒト混濁水晶体を置換して屈折を補正するために水晶体の代用として挿入される眼内レンズが実用に供されている。白内障治療における眼内レンズ挿入手術においては、例えば角膜、強角膜などの縁に数ミリの切開の創口（切開創）が設けられ、超音波水晶体乳化吸引術などにより水晶体が粉砕されて切開創から取り除かれた後、眼内レンズ挿入器具により眼内レンズが挿入及び固定される。 Intraocular lenses that are inserted as a substitute for the crystalline lens in order to correct the refraction by replacing the human turbid crystalline lens in the treatment of cataract are in practical use. In intraocular lens insertion surgery in the treatment of cataracts, for example, a few millimeters of incision wound (incision) is provided at the edge of the cornea, cornea, etc., and the lens is crushed by ultrasonic phacoemulsification, etc. After removal, the intraocular lens is inserted and fixed by an intraocular lens insertion device.
　近年においては、患者への負担などの観点から、切開創はできるだけ小さいことが望ましいと考えられている。ただし、小さい切開創に刺入できる眼内レンズ挿入器具を使用する際には、例えば眼球制御、器具先端を切開創に挿入する際の挿入力など、眼内レンズ挿入時に考慮すべき点がある。そのため、実際の手術を疑似体験できるようにするキットが種々提案されている（例えば特許文献１～４）。 In recent years, it has been considered desirable to make the incision as small as possible from the viewpoint of burden on the patient. However, when using an intraocular lens insertion device that can be inserted into a small incision, there are some points to consider when inserting an intraocular lens, such as eyeball control and insertion force when inserting the tip of the device into the incision. . For this reason, various kits have been proposed that allow for a simulated experience of actual surgery (for example, Patent Documents 1 to 4).
国際公開第２０１０／０８４５９５号International Publication No. 2010/084595 特開２００２－２３６４４３号公報JP 2002-236443 A 特開２００７－１２７７０８号公報JP 2007-127708 A 特表平２－５０２２２４号公報JP-T-2-502224
　しかしながら、上記のキットでは、練習を繰り返す度に疑似角膜あるいは人工角膜を張り替えたりする必要があるため、練習の準備に多くの工数を要するなど、眼内レンズ挿入器具の眼球への挿入操作の練習用キットには適しない可能性がある。 However, in the above kit, it is necessary to replace the artificial cornea or artificial cornea every time the practice is repeated, so that it takes a lot of man-hours to prepare for the practice. It may not be suitable for the kit.
　本件開示の技術は、上記の事情に鑑みてなされたものであり、その目的とするところは、眼内レンズ挿入器具の眼球への挿入操作を、繰り返し疑似体験することが可能な眼内レンズ挿入器具の挿入練習用キットを提供することである。 The technology of the present disclosure has been made in view of the above circumstances, and the purpose of the technique is to insert an intraocular lens capable of repeatedly experiencing the insertion of an intraocular lens insertion device into an eyeball. It is to provide an instrument insertion practice kit.
　本件開示の眼内レンズ挿入器具の挿入練習用キットは、眼内レンズ挿入器具の先端部が挿入される挿入孔と、挿入孔に挿入された眼内レンズ挿入器具の先端部の側面を押圧する押圧部とを有し、押圧部は、眼内レンズ挿入器具の挿入孔を、挿入孔の開口面の法線方向から見たときに、挿入孔の少なくとも一部を占める弾性部材を有する。これにより、練習者は、押圧部を患者の角膜、強角膜などに見立て、眼内レンズ挿入器具の先端部を当該挿入孔に挿入したときの眼内レンズ挿入器具の押し込み力に基づいて、眼内レンズ挿入器具の適切な挿入量を感覚的に把握することができる。そして、練習者は、眼内レンズ挿入器具の挿入量を適切に制御することにより、実際の手術においても、眼内レンズ挿入器具を用いた眼内レンズの射出時に、眼内レンズの射出挙動をより安定させることができると期待される。 The intraocular lens insertion device insertion practice kit of the present disclosure presses the insertion hole into which the distal end portion of the intraocular lens insertion device is inserted and the side surface of the distal end portion of the intraocular lens insertion device inserted into the insertion hole. A pressing portion, and the pressing portion includes an elastic member that occupies at least a part of the insertion hole when the insertion hole of the intraocular lens insertion device is viewed from the normal direction of the opening surface of the insertion hole. Thereby, the practitioner considers the pressing portion as the patient's cornea, cornea, etc., and based on the pushing force of the intraocular lens insertion device when the distal end portion of the intraocular lens insertion device is inserted into the insertion hole, An appropriate insertion amount of the inner lens insertion device can be grasped sensuously. The practitioner appropriately controls the amount of insertion of the intraocular lens insertion device, so that the injection behavior of the intraocular lens can be changed even during actual surgery when the intraocular lens is emitted using the intraocular lens insertion device. Expected to be more stable.
　また、押圧部は、眼内レンズ挿入器具が、眼内レンズ挿入器具の挿入孔への挿入方向に摺動自在となるように、眼内レンズ挿入器具の先端部の側面を押圧するように設けられている。また、挿入孔は、眼内レンズ挿入器具と当接可能に設けられ、眼内レンズ挿入器具が挿入孔に当接するとき、先端部に設けられた眼内レンズを射出するための開口部の一部が、押圧部よりも、眼内レンズ挿入器具の挿入方向後側に位置する。これにより、眼内レンズ挿入器具が挿入孔に当接するとき、眼内レンズ挿入器具の位置は、実際の手術ではレンズ射出挙動不全が発生する可能性がある位置となる。したがって、このように構成された眼内レンズ挿入器具の挿入練習用キットでは、練習者は、レンズ射出挙動不全が発生する可能性がある眼内レンズ挿入器具の挿入状態を把握することができる。 The pressing portion is provided so as to press the side surface of the distal end portion of the intraocular lens insertion device so that the intraocular lens insertion device can slide in the insertion direction of the intraocular lens insertion device into the insertion hole. It has been. The insertion hole is provided so as to be able to come into contact with the intraocular lens insertion device. When the intraocular lens insertion device comes into contact with the insertion hole, the insertion hole is a part of an opening for emitting the intraocular lens provided at the distal end portion. The part is positioned behind the pressing part in the insertion direction of the intraocular lens insertion device. As a result, when the intraocular lens insertion instrument comes into contact with the insertion hole, the position of the intraocular lens insertion instrument becomes a position at which lens ejection behavior failure may occur in actual surgery. Therefore, in the kit for practicing insertion of the intraocular lens insertion device configured as described above, the practitioner can grasp the insertion state of the intraocular lens insertion device that may cause lens ejection behavior failure.
　また、上記の弾性部材は、先端部が挿入される切り込みが設けられているシート部材である。これにより、押圧部を実際の手術において設けられる切開創と同様の構成とすることができるため、練習者は、このように構成された押圧部に眼内レンズ挿入器具を挿入することで、より実地に近い眼内レンズ挿入器具の挿入を練習することができる。 Further, the elastic member is a sheet member provided with a notch into which a tip portion is inserted. Thereby, since a press part can be set as the structure similar to the incision provided in actual surgery, a practitioner can insert more intraocular lens insertion instrument in the press part comprised in this way, and more It is possible to practice the insertion of an intraocular lens insertion device close to the actual situation.
　さらに、眼内レンズ挿入器具の挿入練習用キットは、略半球形状の筐体をさらに有し、挿入孔は、筐体の表面に設けられ、筐体は、挿入孔に挿入された眼内レンズ挿入器具の先端部を観察可能な観察手段を有する。これにより、筐体を患者の眼球に見立て、実際の手術において切開創が設けられる位置に挿入孔を配置することにより、練習者は、より実際の手術に近い状態で眼内レンズ挿入器具の挿入を練習することができる。また、押圧部と弾性部材の少なくとも１つが透明性を有するように構成しても酔い。これにより、練習者にとって、挿入孔に挿入された眼内レンズ挿入器具を確認しやすくなる。 The intraocular lens insertion instrument insertion practice kit further includes a substantially hemispherical housing, the insertion hole is provided on the surface of the housing, and the housing is inserted into the insertion hole. Observation means capable of observing the distal end portion of the insertion instrument. This allows the practitioner to insert the intraocular lens insertion device in a state closer to the actual operation by placing the insertion hole at the position where the incision is provided in the actual operation, with the case like the patient's eyeball. Can practice. Moreover, even if it comprises so that at least 1 of a press part and an elastic member may have transparency, it will get sick. This makes it easier for the practitioner to check the intraocular lens insertion device inserted into the insertion hole.
　本件開示の技術によれば、眼内レンズ挿入器具の眼球への挿入操作を、繰り返し疑似体験することが可能な眼内レンズ挿入器具の練習用キットを提供することができる。 According to the technique disclosed in the present disclosure, it is possible to provide a practice kit for an intraocular lens insertion device capable of repeatedly experiencing the insertion operation of the intraocular lens insertion device into the eyeball.

　以下に、図面を参照して本発明の実施の形態について説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.
〔第１の実施形態〕
　図１に第１の実施形態における眼内レンズ挿入器具の練習用キット１の上面図を示す。また、図２には、図１におけるＡ－Ａ線による断面図を示す。本実施形態では、眼内レンズ挿入器具の練習用キット１は、３枚の円形の透明プレート１０、１１、１２が重ねて組み付けられている。また、眼内レンズ挿入器具の練習用キット１は、ねじ１３～１６とナット１７～２０によって透明プレート１０、１１、１２が互いに固定される。 [First Embodiment]
The top view of the kit 1 for practice of the intraocular lens insertion instrument in 1st Embodiment is shown in FIG. FIG. 2 is a sectional view taken along line AA in FIG. In the present embodiment, the practice kit 1 for an intraocular lens insertion device is assembled with three circular transparent plates 10, 11, and 12 stacked. In the intraocular lens insertion instrument practice kit 1, the transparent plates 10, 11, and 12 are fixed to each other by screws 13 to 16 and nuts 17 to 20.
　本実施形態における眼内レンズ挿入器具の練習用キット１では、透明プレート１０、１１、１２の中心に、眼内レンズ挿入器具の先端部が挿通可能な径を有する挿入孔１０ｈ、１１ｈ、１２ｈが設けられている。なお、透明プレート１０、１２には同一径の孔が設けられる。さらに、透明プレート１１に設けられる挿入孔１１ｈは、ワッシャ２１とＯリング２２が配置できるだけ余分に大きな径を有する孔として設けられる。また、図２に示すように透明プレート１０、１１、１２の挿入孔１０ｈ、１１ｈ、１２ｈは互いに重なるように組み付けられる。なお、Ｏリング２２の外径は透明プレート１０、１２に設けられている挿入孔１０ｈ、１２ｈの径よりも大きく設けられているため、Ｏリング２２がワッシャ２１と共に透明プレート１１の孔に嵌め込まれて透明プレート１０、１２に挟まれて組み付けられた後に、Ｏリング２２が挿入孔１０ｈ、１２ｈから抜け落ちる懸念はない。また、ワッシャ２１およびＯリング２２は、色がなく透明なものが望ましい。これにより、練習者にとっては、ワッシャ２１およびＯリング２２を通して挿入孔１０ｈ、１１ｈ、１２ｈに挿入された眼内レンズ挿入器具を確認しやすくなる。 In the kit for practicing the intraocular lens insertion device in the present embodiment, insertion holes 10h, 11h, and 12h having a diameter through which the distal end portion of the intraocular lens insertion device can be inserted are located at the centers of the transparent plates 10, 11, and 12. Is provided. The transparent plates 10 and 12 are provided with holes having the same diameter. Furthermore, the insertion hole 11h provided in the transparent plate 11 is provided as a hole having a diameter that is excessively large as long as the washer 21 and the O-ring 22 can be arranged. 2, the insertion holes 10h, 11h, and 12h of the transparent plates 10, 11, and 12 are assembled so as to overlap each other. Since the outer diameter of the O-ring 22 is larger than the diameter of the insertion holes 10 h and 12 h provided in the transparent plates 10 and 12, the O-ring 22 is fitted into the hole of the transparent plate 11 together with the washer 21. There is no concern that the O-ring 22 will fall out of the insertion holes 10h and 12h after being sandwiched and assembled between the transparent plates 10 and 12. The washer 21 and the O-ring 22 are preferably transparent without color. This makes it easier for the practitioner to check the intraocular lens insertion device inserted into the insertion holes 10h, 11h, and 12h through the washer 21 and the O-ring 22.
　本実施形態の眼内レンズ挿入器具の練習用キット１では、Ｏリング２２が実際の手術における患者の角膜、強角膜などの代わりとして用いられる。なお、図ではワッシャ２１およびＯリング２２の寸法は透明プレート１０、１１、１２との間に隙間が生じないように設けられているが、ワッシャ２１およびＯリング２２と透明プレート１０、１１、１２との間に空間が設けられるように、ワッシャ２１およびＯリングの寸法を設定してもよい。この場合、眼内レンズ挿入器具２がＯリング２２に挿入される際に、ワッシャ２１およびＯリング２２が、透明プレート１０、１１、１２との間に設けられた空間内を移動する。これにより、Ｏリング２２の孔と透明プレート１０、１１、１２に設けられる挿入孔１０ｈ、１１ｈ、１２ｈとの中心合わせを好適に行うことができる。なお、ワッシャ２１の内径を調節することで、ワッシャ２１に嵌め込まれたＯリング２２の内径を制御することができる。これにより、眼内レンズ挿入器具２がＯリング２２に挿入されたときに、Ｏリング２２による眼内レンズ挿入器具２の押圧力を調節することができる。 In the practice kit 1 for the intraocular lens insertion device of the present embodiment, the O-ring 22 is used as a substitute for the patient's cornea, cornea, etc. in actual surgery. In the figure, the dimensions of the washer 21 and the O-ring 22 are provided so that no gap is formed between the transparent plates 10, 11, and 12, but the washer 21 and the O-ring 22 and the transparent plates 10, 11, and 12 are provided. The dimensions of the washer 21 and the O-ring may be set so that a space is provided between the two. In this case, when the intraocular lens insertion device 2 is inserted into the O-ring 22, the washer 21 and the O-ring 22 move in a space provided between the transparent plates 10, 11, and 12. Thereby, center alignment of the hole of the O-ring 22 and the insertion holes 10h, 11h, and 12h provided in the transparent plates 10, 11, and 12 can be suitably performed. The inner diameter of the O-ring 22 fitted in the washer 21 can be controlled by adjusting the inner diameter of the washer 21. Thereby, when the intraocular lens insertion device 2 is inserted into the O-ring 22, the pressing force of the intraocular lens insertion device 2 by the O-ring 22 can be adjusted.
　本実施形態の眼内レンズ挿入器具の練習用キット１では、一例として、透明プレート１０、１２に設けられる挿入孔１０ｈ、１２ｈの径を２．５ｍｍ、Ｏリング２２の内径を１．２５ｍｍ、透明プレート１０、１１、１２の各プレートの厚さを１．０ｍｍとなるように構成される。本実施形態において、眼内レンズ挿入器具の練習用キット１には、眼内レンズ挿入器具の先端部を透明プレート１２側から挿入する。本実施形態では、Ｏリング２２の透明プレート１２側の面Ｐ１から透明プレート１０の上面Ｐ２までの孔をトンネルと称し、トンネル長さを２．０ｍｍとなるように構成する。 In the kit for practicing the intraocular lens insertion instrument of the present embodiment, as an example, the diameter of the insertion holes 10h and 12h provided in the transparent plates 10 and 12 is 2.5 mm, the inner diameter of the O-ring 22 is 1.25 mm, and the transparent The plates 10, 11, and 12 are configured to have a thickness of 1.0 mm. In the present embodiment, the distal end portion of the intraocular lens insertion device is inserted into the practice kit 1 for the intraocular lens insertion device from the transparent plate 12 side. In the present embodiment, the hole from the surface P1 on the transparent plate 12 side of the O-ring 22 to the upper surface P2 of the transparent plate 10 is referred to as a tunnel, and the tunnel length is set to 2.0 mm.
　図３に、本実施形態の眼内レンズ挿入器具の練習用キット１に眼内レンズ挿入器具２の先端部を挿入したときの例を模式的に示す。図３は、眼内レンズ挿入器具の練習用キット１に対する眼内レンズ挿入器具２の挿入量が少ない場合を示している。なお、本実施形態において、組付けが完了した眼内レンズ挿入器具の練習用キット１は、バイスなどの位置固定器具を用いて固定され、練習者は固定された眼内レンズ挿入器具の練習用キット１に眼内レンズ挿入器具２の先端部を挿入する。 FIG. 3 schematically shows an example when the distal end portion of the intraocular lens insertion device 2 is inserted into the practice kit 1 for the intraocular lens insertion device of the present embodiment. FIG. 3 shows a case where the insertion amount of the intraocular lens insertion device 2 with respect to the practice kit 1 for the intraocular lens insertion device is small. In this embodiment, the practice kit 1 for the intraocular lens insertion instrument that has been assembled is fixed by using a position fixing instrument such as a vise, and the practitioner is for practicing the fixed intraocular lens insertion instrument. The tip of the intraocular lens insertion device 2 is inserted into the kit 1.
　図３に示すように、眼内レンズ挿入器具の練習用キット１に対する眼内レンズ挿入器具２の先端部の挿入量が少ないと、眼内レンズ挿入器具２の先端部のトンネルからの突出量（長さ）Ｄが、後述する図４の場合に比べて少ない。さらに、眼内レンズ挿入器具２の開口部２３の一部が、Ｏリング２２の透明プレート１２側の面Ｐ１よりも透明プレート１２側に存在する。このため、練習者が、眼内レンズ挿入器具２が備える眼内レンズを押し出すためのプランジャー（図示せず）を操作して、眼内レンズを眼内レンズ挿入器具２の先端部側に移動すると、眼内レンズが、開口部２３のトンネル側の領域ではなくＯリング２２の面Ｐ１より透明プレート１２側を通って、眼内レンズ挿入器具２から射出される可能性がある。これは、実際の手術におけるレンズ射出挙動不全に相当する。 As shown in FIG. 3, when the insertion amount of the distal end portion of the intraocular lens insertion device 2 with respect to the practice kit 1 for the intraocular lens insertion device is small, the projection amount from the tunnel at the distal end portion of the intraocular lens insertion device 2 ( The length D is smaller than that in the case of FIG. 4 described later. Furthermore, a part of the opening 23 of the intraocular lens insertion device 2 is present on the transparent plate 12 side of the surface P1 of the O-ring 22 on the transparent plate 12 side. For this reason, the practitioner operates a plunger (not shown) for pushing out the intraocular lens provided in the intraocular lens insertion device 2 to move the intraocular lens toward the distal end side of the intraocular lens insertion device 2. Then, there is a possibility that the intraocular lens is emitted from the intraocular lens insertion device 2 through the transparent plate 12 side from the surface P1 of the O-ring 22 instead of the region on the tunnel side of the opening 23. This corresponds to a lens ejection behavior failure in actual surgery.
　レンズ射出挙動不全とは、例えば、眼内レンズ挿入器具２から眼内レンズを射出する際に、眼内レンズが眼内に案内されずに角膜、強角膜などの外側、すなわち眼外に移動してしまう現象である。レンズ射出挙動不全は、例えば、角膜、強角膜などの切開創に対する眼内レンズ挿入器具２の先端部の挿入量が少ないために、眼内レンズ挿入器具２の先端部の開口部２３の一部が切開創の外側に位置することで、眼内レンズが、切開創の外側に位置する開口部２３の一部から射出されることで発生する。 For example, when the intraocular lens is ejected from the intraocular lens insertion device 2, the intraocular lens is not guided into the eye and moves outside the cornea, cornea, or the like, that is, outside the eye. It is a phenomenon that ends up. Insufficient lens ejection behavior is caused by, for example, a small amount of insertion of the distal end portion of the intraocular lens insertion device 2 into an incision such as the cornea or cornea, and thus a part of the opening 23 at the distal end portion of the intraocular lens insertion device 2. Is located outside the incision, and the intraocular lens is emitted from a part of the opening 23 located outside the incision.
　次に、図４に、本実施形態の眼内レンズ挿入器具の練習用キット１に眼内レンズ挿入器具２の先端部を挿入し、練習者が眼内レンズ挿入器具２を眼内レンズ挿入器具の練習用キット１に押し込んでいったときの例を模式的に示す。図４に示す例では、眼内レンズ挿入器具の練習用キット１に対する眼内レンズ挿入器具２の挿入量が適切である、すなわち実際の手術においてレンズ射出挙動不全が発生する可能性がない場合を示している。なお、図４に示す眼内レンズ挿入器具の練習用キット１も、図３と同様に、バイスなどの位置固定器具を用いて固定されている。 Next, in FIG. 4, the distal end portion of the intraocular lens insertion device 2 is inserted into the practice kit 1 for the intraocular lens insertion device of the present embodiment, and the practitioner inserts the intraocular lens insertion device 2 into the intraocular lens insertion device. An example of pushing into the practice kit 1 is schematically shown. In the example shown in FIG. 4, the insertion amount of the intraocular lens insertion device 2 with respect to the practice kit 1 for the intraocular lens insertion device is appropriate, that is, there is no possibility that lens ejection behavior failure will occur in actual surgery. Show. The practice kit 1 for the intraocular lens insertion device shown in FIG. 4 is also fixed using a position fixing device such as a vice, as in FIG.
　図４に示すように、眼内レンズ挿入器具の練習用キット１に対する眼内レンズ挿入器具２の先端部の挿入量が十分であると、眼内レンズ挿入器具２の先端部のトンネルからの突出量（長さ）Ｄが、上述の図３の場合に比べて多い。さらに、眼内レンズ挿入器具２の開口部２３全体が、Ｏリング２２の面Ｐ１よりも透明プレート１０側、すなわちトンネル内に存在する。 As shown in FIG. 4, when the amount of insertion of the distal end portion of the intraocular lens insertion device 2 into the intraocular lens insertion device practice kit 1 is sufficient, the distal end portion of the intraocular lens insertion device 2 protrudes from the tunnel. The amount (length) D is larger than that in the case of FIG. Further, the entire opening 23 of the intraocular lens insertion device 2 is present on the transparent plate 10 side of the surface P1 of the O-ring 22, that is, in the tunnel.
　このため、図３の場合とは異なり、練習者が、眼内レンズ挿入器具２のプランジャーを操作して、眼内レンズを眼内レンズ挿入器具２の先端部側に移動するときに、眼内レンズがＯリング２２の面Ｐ１よりも透明プレート１２側に射出される可能性はない。したがって、図３の場合のように実際の手術におけるレンズ射出挙動不全は発生しない。 Therefore, unlike the case of FIG. 3, the practitioner operates the plunger of the intraocular lens insertion device 2 to move the intraocular lens toward the distal end side of the intraocular lens insertion device 2. There is no possibility that the inner lens is emitted to the transparent plate 12 side from the surface P1 of the O-ring 22. Therefore, the lens ejection behavior failure does not occur in actual surgery as in the case of FIG.
　本実施形態において、図１～図４に示すように、Ｏリング２２は、挿入孔１０ｈの開口面Ｐ３（図２～図４では点線にて示す）の法線方向から、すなわち図１では紙面に垂直な方向から、図２～図４では紙面の上下方向から見たときに、挿入孔１０ｈの一部を占めるように構成されている。また、練習者による眼内レンズ挿入器具２のＯリング２２への押し込み力が大きくなるほど、眼内レンズ挿入器具の練習用キット１に対する眼内レンズ挿入器具２の挿入量は多くなる。 In this embodiment, as shown in FIGS. 1 to 4, the O-ring 22 is formed from the normal direction of the opening surface P3 of the insertion hole 10h (shown by a dotted line in FIGS. 2 to 4), that is, in FIG. 2 to 4 are configured to occupy a part of the insertion hole 10h when viewed from the vertical direction of the paper surface in FIGS. Moreover, the amount of insertion of the intraocular lens insertion device 2 into the practice kit 1 of the intraocular lens insertion device increases as the practitioner pushes the intraocular lens insertion device 2 into the O-ring 22.
　したがって、練習者は、眼内レンズ挿入器具２のＯリング２２への押し込み力が不十分であり、図３の場合のようにレンズ射出挙動不全が発生してしまう可能性があるときは、図４に示す位置になるまで眼内レンズ挿入器具２をさらにトンネル側に押し込む。これにより、練習者は、眼内レンズ挿入器具の練習用キット１に対する眼内レンズ挿入器具２の適切な挿入量を、眼内レンズ挿入器具２のＯリング２２への押し込み力に基づいて感覚的に把握することができる。さらに、Ｏリング２２および透明プレート１０、１１、１２が透明部材で形成されていることから、練習者は、眼内レンズ挿入器具２の先端部のトンネルからの突出量（長さ）Ｄを確認し、眼内レンズ挿入器具の練習用キット１に対する眼内レンズ挿入器具２の適切な挿入量を目視で確認することもできる。 Accordingly, when the practitioner has insufficient pushing force into the O-ring 22 of the intraocular lens insertion device 2 and there is a possibility that the lens ejection behavior failure may occur as in the case of FIG. The intraocular lens insertion device 2 is further pushed into the tunnel side until the position shown in FIG. As a result, the practitioner senses the appropriate amount of insertion of the intraocular lens insertion device 2 into the practice kit 1 for the intraocular lens insertion device based on the pushing force of the intraocular lens insertion device 2 into the O-ring 22. Can grasp. Furthermore, since the O-ring 22 and the transparent plates 10, 11, 12 are formed of transparent members, the practitioner confirms the amount of protrusion (length) D from the tunnel at the distal end of the intraocular lens insertion device 2. In addition, an appropriate insertion amount of the intraocular lens insertion device 2 with respect to the practice kit 1 for the intraocular lens insertion device can be confirmed visually.

Next, a practice kit 100 for an intraocular lens insertion device according to a second embodiment will be described with reference to the drawings. FIG. 5 shows a perspective view of a practice kit 100 for an intraocular lens insertion device according to the second embodiment. FIG. 6 shows a top view of the practice kit 100 for the intraocular lens insertion device. FIG. 7 shows a side view of the practice kit 100 for the intraocular lens insertion device. As shown in FIGS. 5 to 7, the practice kit 100 for an intraocular lens insertion device includes a base plate 101, a support portion 102, and a dome portion 103. A support portion 102 is placed on the base plate 101, and a dome portion 103 is connected on the support portion 102. The base plate 101 is a substantially square flat plate member. The support part 102 is a hollow cylindrical member. The dome portion 103 is a substantially hemispherical member. In addition, the outer shape of the dome portion 103 is formed assuming the corneal shape of the patient's eyeball.
　図５、図６に示すように、本実施形態に係る眼内レンズ挿入器具の練習用キット１００は、ドーム部１０３に観察窓１０４、眼内レンズ挿入器具の挿入部１０５、プレート保持部１０６をそれぞれ有する。観察窓１０４は、ドーム部１０３を貫通する略円形の孔にＰＭＭＡ（Polymethyl Methacrylate）などの透明性を有する窓材が嵌め込まれて構成されている。したがって、観察窓１０４からドーム部１０３内を確認することができる。 As shown in FIGS. 5 and 6, an intraocular lens insertion instrument practice kit 100 according to this embodiment includes an observation window 104, an intraocular lens insertion instrument insertion part 105, and a plate holding part 106 in a dome part 103. Have each. The observation window 104 is configured by fitting a transparent window material such as PMMA (Polymethyl Methacrylate) into a substantially circular hole penetrating the dome portion 103. Therefore, the inside of the dome 103 can be confirmed from the observation window 104.
　図８に、図６のＢ－Ｂ線による眼内レンズ挿入器具の練習用キット１００の断面図を示す。図８に示すように、本実施形態に係る眼内レンズ挿入器具の練習用キット１００の観察窓１０４は、窓材１０４ａ、窓材１０４ａを受ける受け部１０４ｂ、ドーム部１０３を貫通する貫通孔１０４ｃを有する。また、眼内レンズ挿入器具の挿入部１０５は、透明プレート１０５ａ、Ｏリング１０５ｃを保持するワッシャ１０５ｂ、Ｏリング１０５ｃ、ドーム部１０３を貫通する貫通孔１０５ｄを有する。透明プレート１０５ａには、眼内レンズ挿入器具の先端部を挿入するための挿入孔１０５ｈが設けられている。 FIG. 8 shows a cross-sectional view of the practice kit 100 for the intraocular lens insertion device taken along line BB in FIG. As shown in FIG. 8, the observation window 104 of the kit for practicing the intraocular lens insertion device according to this embodiment includes a window member 104a, a receiving portion 104b that receives the window member 104a, and a through hole 104c that passes through the dome portion 103. Have The insertion part 105 of the intraocular lens insertion instrument has a transparent plate 105 a, a washer 105 b that holds the O-ring 105 c, an O-ring 105 c, and a through-hole 105 d that penetrates the dome part 103. The transparent plate 105a is provided with an insertion hole 105h for inserting the distal end portion of the intraocular lens insertion instrument.
　図８に示すように、ワッシャ１０５ｂおよびＯリング１０５ｃは、ドーム部１０３に設けられた凹部に嵌め込まれている。そして、透明プレート１０５ａがワッシャ１０５ｂおよびＯリング１０５ｃに当接して覆うように配置され、透明プレート１０５aは、プレート保持部１０６によって保持されている。本実施形態において、Ｏリング１０５ｃが実際の手術における患者の角膜、強角膜などに対応する。 As shown in FIG. 8, the washer 105 b and the O-ring 105 c are fitted into a recess provided in the dome portion 103. The transparent plate 105 a is disposed so as to contact and cover the washer 105 b and the O-ring 105 c, and the transparent plate 105 a is held by the plate holding unit 106. In this embodiment, the O-ring 105c corresponds to a patient's cornea, cornea, etc. in actual surgery.
　プレート保持部１０６は、ドーム部１０３に対して着脱可能に取り付けられる。眼内レンズ挿入器具の練習用キット１００の使用者は、プレート保持部１０６を取り外し、プレート保持部１０６が取り外された箇所から透明プレート１０５ａを眼内レンズ挿入器具の挿入部１０５にセットする。透明プレート１０５ａのセットが完了したら、プレート保持部１０６を再度ドーム部１０３に取り付ける。プレート保持部１０６がないと、セットされた透明プレート１０５ａが眼内レンズ挿入器具の挿入部１０５から脱落してしまう。したがって、プレート保持部１０６をドーム部１０３に取り付けることにより、眼内レンズ挿入器具の挿入部１０５にセットされた透明プレート１０５ａは、プレート保持部１０６によって保持された状態となる。 The plate holding part 106 is detachably attached to the dome part 103. The user of the intraocular lens insertion device practice kit 100 removes the plate holding unit 106 and sets the transparent plate 105a on the insertion unit 105 of the intraocular lens insertion device from the position where the plate holding unit 106 is removed. When the setting of the transparent plate 105 a is completed, the plate holding unit 106 is attached to the dome unit 103 again. Without the plate holding portion 106, the set transparent plate 105a falls off the insertion portion 105 of the intraocular lens insertion device. Therefore, by attaching the plate holding part 106 to the dome part 103, the transparent plate 105a set in the insertion part 105 of the intraocular lens insertion device is held by the plate holding part 106.
　なお、本実施形態において、ドーム部１０３は眼球の角膜形状を想定して形成されており、ドーム部１０３の表面に設けられる眼内レンズ挿入器具の挿入部１０５の位置は、通常の手術において設けられる切開創の位置に対応している。このため、練習者は、挿入部１０５に対する眼内レンズ挿入器具の挿入角度なども、実際の手術と同じように練習することができる。 In this embodiment, the dome portion 103 is formed on the assumption that the corneal shape of the eyeball is formed, and the position of the insertion portion 105 of the intraocular lens insertion instrument provided on the surface of the dome portion 103 is provided in normal surgery. Corresponds to the position of the incision. For this reason, the practitioner can practice the insertion angle of the intraocular lens insertion device with respect to the insertion portion 105 in the same manner as in actual surgery.
　なお、本実施形態においてＯリング１０５ｃは断面が円形であるが、第１の実施形態と同様、断面が他の形状であるＯリング１０５ｃを用いてもよい。また、図８に示すように、プレート保持部１０６は、ドーム部１０３に取り付けられると、眼内レンズ挿入器具の挿入部１０５にセットされた透明プレート１０５ａと係合し、透明プレート１０５ａが眼内レンズ挿入器具の挿入部１０５から脱落しないように透明プレート１０５ａを保持する。 In this embodiment, the O-ring 105c has a circular cross section, but an O-ring 105c having a different cross section may be used as in the first embodiment. As shown in FIG. 8, when the plate holding unit 106 is attached to the dome unit 103, the plate holding unit 106 engages with the transparent plate 105a set in the insertion unit 105 of the intraocular lens insertion device, and the transparent plate 105a The transparent plate 105a is held so as not to drop off from the insertion portion 105 of the lens insertion device.
　本実施形態において、透明プレート１０５ａに設けられる挿入孔１０５ｈの径、Ｏリング１０５ｃの内径、貫通孔１０５ｄの径は、それぞれ第１の実施形態における、透明プレート１２に設けられる挿入孔１２ｈの径、Ｏリング２２の内径、透明プレート１０に設けられる貫通孔の径と同様に設定される。さらに、透明プレート１０５ａのワッシャ１０５ｂと接する面１０５ｅから貫通孔１０５ｄのドーム部１０３の内側の開口までの範囲を第１の実施形態と同様にトンネルと称してその長さをＬとし、眼内レンズ挿入器具の挿入部１０５に眼内レンズ挿入器具を挿入するときの眼内レンズ挿入器具の先端部のトンネルからの突出量をＤとする。 In the present embodiment, the diameter of the insertion hole 105h provided in the transparent plate 105a, the inner diameter of the O-ring 105c, and the diameter of the through hole 105d are respectively the diameter of the insertion hole 12h provided in the transparent plate 12 in the first embodiment, It is set similarly to the inner diameter of the O-ring 22 and the diameter of the through hole provided in the transparent plate 10. Further, the range from the surface 105e contacting the washer 105b of the transparent plate 105a to the inner opening of the dome portion 103 of the through hole 105d is referred to as a tunnel as in the first embodiment, and its length is L. Let D be the amount of protrusion of the tip of the intraocular lens insertion device from the tunnel when the intraocular lens insertion device is inserted into the insertion unit 105 of the insertion device.
　図９、１０に、本実施形態の眼内レンズ挿入器具の練習用キット１００に眼内レンズ挿入器具２を挿入する例を示す。図９は、眼内レンズ挿入器具２の挿入量が少ない場合を、図１０は、眼内レンズ挿入器具２の挿入量が適切である場合をそれぞれ示す。図３、４を参照しながら説明した場合と同様、図９の場合は、眼内レンズ挿入器具２の先端部の開口部２３のうち、トンネル手前すなわちＯリング１０５ｃよりも透明プレート１０５ａ側の領域から眼内レンズが射出される可能性がある。一方、図１０の場合は、眼内レンズ挿入器具２の開口部２３はトンネル内あるいはドーム部１０３内にあるため、眼内レンズがトンネル手前に射出される可能性はない。 9 and 10 show an example in which the intraocular lens insertion device 2 is inserted into the practice kit 100 for the intraocular lens insertion device of the present embodiment. FIG. 9 shows a case where the insertion amount of the intraocular lens insertion device 2 is small, and FIG. 10 shows a case where the insertion amount of the intraocular lens insertion device 2 is appropriate. As in the case described with reference to FIGS. 3 and 4, in the case of FIG. 9, in the opening 23 at the distal end of the intraocular lens insertion device 2, the region before the tunnel, that is, the region closer to the transparent plate 105 a than the O-ring 105 c. There is a possibility that an intraocular lens is ejected from. On the other hand, in the case of FIG. 10, since the opening 23 of the intraocular lens insertion device 2 is in the tunnel or the dome 103, there is no possibility that the intraocular lens is emitted before the tunnel.
　したがって、第１の実施形態と同様、本実施形態の眼内レンズ挿入器具の練習用キット１００においても、練習者は、眼内レンズ挿入器具２の押し込み力に基づいて、レンズ射出挙動不全が発生する可能性があるか否かを感覚的に把握することができる。さらに、本実施形態では、練習者は、観察窓１０４からトンネルから突出した眼内レンズ挿入器具２の先端部の状態を確認することができる。これにより、練習者は、観察窓１０４から眼内レンズ挿入器具２の先端部の状態を確認しつつ、最適な眼内レンズ挿入器具２の押し込み力を把握することができる。 Therefore, similarly to the first embodiment, in the kit for practicing the intraocular lens insertion device according to the present embodiment, the practitioner has a lens ejection behavior failure based on the pushing force of the intraocular lens insertion device 2. It is possible to grasp sensuously whether or not there is a possibility of doing. Furthermore, in this embodiment, the practitioner can confirm the state of the distal end portion of the intraocular lens insertion device 2 that protrudes from the observation window 104 through the tunnel. Thereby, the practitioner can grasp the optimal pushing force of the intraocular lens insertion device 2 while confirming the state of the distal end portion of the intraocular lens insertion device 2 from the observation window 104.
　以上が本実施形態に関する説明であるが、上記の眼内レンズ挿入器具の練習用キットなどの構成は、上記の実施形態に限定されるものではなく、本発明の技術的思想と同一性を失わない範囲内において種々の変更が可能である。例えば、上記の説明において、透明プレート１０の上面Ｐ２に着色を施してもよい。これにより、練習者にとっては、眼内レンズ挿入器具の練習用キット１の透明プレート１０の上面Ｐ２から突出する眼内レンズ挿入器具２の先端部を認識しやすくなる。なお、透明プレート１０の上面Ｐ２に限らず、透明プレート１０の下面、あるいは透明プレート１１、１２の上面または下面に着色を施してもよい。 The above is the description of the present embodiment, but the configuration of the above-described practice kit for the intraocular lens insertion device is not limited to the above-described embodiment, and loses the same technical idea as the present invention. Various modifications can be made within a range that does not exist. For example, in the above description, the upper surface P2 of the transparent plate 10 may be colored. This makes it easier for the practitioner to recognize the distal end portion of the intraocular lens insertion device 2 protruding from the upper surface P2 of the transparent plate 10 of the practice kit 1 for the intraocular lens insertion device. In addition, you may color not only the upper surface P2 of the transparent plate 10, but the lower surface of the transparent plate 10, or the upper surface or lower surface of the transparent plates 11 and 12. FIG.
　例えば、以下に上記の実施形態の変形例を３例説明する。なお、上記の各実施形態および下記の各変形例に示す構成は、適宜組み合わせてもよい。また、以下の説明において上記の各実施形態と同様の構成には同一の符号を付し、詳細な説明は省略する。 For example, three modified examples of the above embodiment will be described below. In addition, you may combine suitably the structure shown to said each embodiment and each following modification. Moreover, in the following description, the same code | symbol is attached | subjected to the structure similar to said each embodiment, and detailed description is abbreviate | omitted.
〔第１の変形例〕
　以下に、第１の変形例に係る眼内レンズ挿入器具の練習用キット１０００について説明する。また、第１の変形例に係る眼内レンズ挿入器具の練習用キット１０００においては、眼内レンズ挿入器具の先端部が挿通可能な径を有する２つの挿入部１０１０、１０１１が設けられている。また、挿入部１０１０、１０１１には、眼内レンズ挿入器具の先端部が挿入される挿入孔１０１０ｈ、１０１１ｈがそれぞれ設けられている。そして、挿入孔１０１０ｈは第１の実施形態の挿入孔１２ｈと同様の径により形成され、挿入孔１０１１ｈは挿入孔１０１０ｈよりもさらに小径の孔として形成されている。また、挿入孔１０１０ｈ、１０１１ｈは、それぞれワッシャ１０２１、１０３１およびＯリング１０２２、１０３２を有する。本変形例においてもＯリング１０２２、１０３２が、実際の手術における患者の角膜、強角膜などに対応している。このため、後述するように、眼内レンズ挿入器具２を挿入孔１０１１ｈに挿入する場合、眼内レンズ挿入器具２の先端部は挿入孔１０１１ｈを挿通することができるが、眼内レンズ挿入器具２の本体は、その径が挿入孔１０１１ｈの径より大きいため挿入孔１０１１ｈに当接して挿通することができない。 [First Modification]
Below, the kit 1000 for practice of the intraocular lens insertion device which concerns on a 1st modification is demonstrated. Moreover, in the kit 1000 for practice of the intraocular lens insertion device according to the first modification, two insertion portions 1010 and 1011 having a diameter through which the distal end portion of the intraocular lens insertion device can be inserted are provided. The insertion portions 1010 and 1011 are provided with insertion holes 1010h and 1011h into which the distal end portions of the intraocular lens insertion device are inserted, respectively. The insertion hole 1010h is formed with the same diameter as the insertion hole 12h of the first embodiment, and the insertion hole 1011h is formed as a hole having a smaller diameter than the insertion hole 1010h. The insertion holes 1010h and 1011h have washers 1021 and 1031 and O- rings 1022 and 1032, respectively. Also in this modification, the O- rings 1022 and 1032 correspond to the patient's cornea, cornea, etc. in actual surgery. Therefore, as will be described later, when the intraocular lens insertion device 2 is inserted into the insertion hole 1011h, the distal end portion of the intraocular lens insertion device 2 can pass through the insertion hole 1011h. Since the diameter of the main body is larger than the diameter of the insertion hole 1011h, the main body cannot be inserted into contact with the insertion hole 1011h.
　図１２に、図１１のＣ－Ｃ線による眼内レンズ挿入器具の練習用キット１０００の断面図を示す。図１２に示すように、眼内レンズ挿入器具の練習用キット１０００の挿入孔１０１０ｈに眼内レンズ挿入器具２が挿入される場合、図４の場合と同様、練習者による眼内レンズ挿入器具２の押し込み力に応じて適切な位置まで眼内レンズ挿入器具２が挿入孔１０１０ｈ内を移動する。一方、挿入孔１０１１ｈに眼内レンズ挿入器具２が挿入される場合、図１２に示すように眼内レンズ挿入器具２が挿入孔１０１１ｈの縁に当接し、眼内レンズ挿入器具２を上記の適切な位置まで移動させることができない。したがって、眼内レンズ挿入器具２を挿入孔１０１１ｈに挿入する場合は、必然的に挿入量が不十分で適切でなくレンズ射出挙動不全が発生する可能性がある状態となる。 FIG. 12 is a cross-sectional view of the practice kit 1000 for the intraocular lens insertion device taken along the line CC of FIG. As shown in FIG. 12, when the intraocular lens insertion device 2 is inserted into the insertion hole 1010h of the intraocular lens insertion device practice kit 1000, the intraocular lens insertion device 2 by the practitioner is the same as in FIG. The intraocular lens insertion device 2 moves through the insertion hole 1010h to an appropriate position in accordance with the pushing force of. On the other hand, when the intraocular lens insertion device 2 is inserted into the insertion hole 1011h, the intraocular lens insertion device 2 comes into contact with the edge of the insertion hole 1011h as shown in FIG. It cannot be moved to a correct position. Therefore, when the intraocular lens insertion device 2 is inserted into the insertion hole 1011h, the amount of insertion is inevitably insufficient, and the lens ejection behavior is likely to be inadequate.
　このように、本変形例では、眼内レンズ挿入器具２を挿入孔１０１０ｈだけでなく挿入孔１０１１ｈにも挿入可能となるように、眼内レンズ挿入器具の練習用キット１０００を構成することで、練習者は、眼内レンズ挿入器具２を挿入孔１０１０ｈに挿入する場合は、眼内レンズ挿入器具２の挿入量が適切となる場合の眼内レンズ挿入器具２の押し込み力を把握することができ、眼内レンズ挿入器具２を挿入孔１０１１ｈに挿入する場合は、レンズ射出挙動不全となる場合の眼内レンズ挿入器具２のＯリング１０３２への挿入状態を把握することができる。 Thus, in this modification, by configuring the intraocular lens insertion device practice kit 1000 so that the intraocular lens insertion device 2 can be inserted not only into the insertion hole 1010h but also into the insertion hole 1011h, When inserting the intraocular lens insertion device 2 into the insertion hole 1010h, the practitioner can grasp the pushing force of the intraocular lens insertion device 2 when the insertion amount of the intraocular lens insertion device 2 is appropriate. When the intraocular lens insertion device 2 is inserted into the insertion hole 1011h, it is possible to grasp the insertion state of the intraocular lens insertion device 2 into the O-ring 1032 when the lens ejection behavior is incomplete.
〔第２の変形例〕
　以下に、第２の変形例に係る眼内レンズ挿入器具の練習用キット２０００について説明する。また、第２の変形例に係る眼内レンズ挿入器具の練習用キット２０００においては、眼内レンズ挿入器具２の先端部が挿通可能な挿入部が２つ設けられている。そして、一方の挿入部２０１０において、透明プレート２０１０ａに設けられる挿入孔２０１０ｈの径、Ｏリング２０１０ｃの内径、貫通孔２０１０ｄの径は、第２の実施形態の挿入孔１０５ｈと同様に構成される。また、もう一方の挿入部２０１１において、透明プレート２０１１ａに設けられる挿入孔２０１１ｈの径、Ｏリング２０１１ｃの内径、貫通孔２０１１ｄの径は、挿入部２０１０の挿入孔２０１０ｈの径、Ｏリング２０１０ｃの内径、貫通孔２０１０ｄの径よりもそれぞれ小径となるように構成される。 [Second Modification]
Below, the kit 2000 for practice of the intraocular lens insertion device which concerns on a 2nd modification is demonstrated. In addition, in the kit for practicing the intraocular lens insertion device according to the second modification, two insertion portions through which the distal end portion of the intraocular lens insertion device 2 can be inserted are provided. In one insertion portion 2010, the diameter of the insertion hole 2010h provided in the transparent plate 2010a, the inner diameter of the O-ring 2010c, and the diameter of the through-hole 2010d are configured in the same manner as the insertion hole 105h of the second embodiment. Moreover, in the other insertion part 2011, the diameter of the insertion hole 2011h provided in the transparent plate 2011a, the inner diameter of the O-ring 2011c, and the diameter of the through-hole 2011d are the diameter of the insertion hole 2010h of the insertion part 2010, and the inner diameter of the O-ring 2010c. The diameter of each through hole 2010d is smaller than that of the through hole 2010d.
　このため、後述するように、眼内レンズ挿入器具２を挿入孔２０１１ｈに挿入する場合、眼内レンズ挿入器具２の先端部は挿入孔２０１１ｈを挿通することができるが、眼内レンズ挿入器具２の本体は、その径が挿入孔２０１１ｈの径より大きいため挿入孔２０１１ｈに当接して挿通することができない。 Therefore, as described later, when the intraocular lens insertion device 2 is inserted into the insertion hole 2011h, the distal end portion of the intraocular lens insertion device 2 can be inserted through the insertion hole 2011h. Since the diameter of the main body is larger than the diameter of the insertion hole 2011h, the main body cannot be inserted into contact with the insertion hole 2011h.
　図１４に、眼内レンズ挿入器具２を挿入孔２０１０ｈに挿入する場合の例を示す。また、図１５に眼内レンズ挿入器具２を挿入孔２０１１ｈに挿入する場合の例を示す。図１４に示すように、挿入孔２０１０ｈに眼内レンズ挿入器具２が挿入される場合、図１０の場合と同様、練習者による眼内レンズ挿入器具２の押し込み力に応じて適切な位置まで眼内レンズ挿入器具２が挿入孔２０１０ｈ内を移動する。一方、挿入孔２０１１ｈに眼内レンズ挿入器具２が挿入される場合、図１５に示すように眼内レンズ挿入器具２が挿入孔２０１１ｈの縁に当接し、眼内レンズ挿入器具２を上記の適切な位置まで移動させることができない。したがって、眼内レンズ挿入器具２を挿入孔２０１１ｈに挿入する場合は、必然的に挿入量が不十分で適切でなくレンズ射出挙動不全が発生する可能性がある状態となる。 FIG. 14 shows an example in which the intraocular lens insertion device 2 is inserted into the insertion hole 2010h. FIG. 15 shows an example in which the intraocular lens insertion device 2 is inserted into the insertion hole 2011h. As shown in FIG. 14, when the intraocular lens insertion device 2 is inserted into the insertion hole 2010h, the eye reaches an appropriate position according to the pushing force of the intraocular lens insertion device 2 by the practitioner, as in FIG. The inner lens insertion device 2 moves in the insertion hole 2010h. On the other hand, when the intraocular lens insertion device 2 is inserted into the insertion hole 2011h, the intraocular lens insertion device 2 comes into contact with the edge of the insertion hole 2011h as shown in FIG. It cannot be moved to a correct position. Therefore, when the intraocular lens insertion device 2 is inserted into the insertion hole 2011h, the amount of insertion is inevitably insufficient and is not appropriate, and there is a possibility that lens ejection behavior failure may occur.
　このように、本変形例では、眼内レンズ挿入器具２を挿入孔２０１０ｈだけでなく挿入孔２０１１ｈにも挿入可能となるように、眼内レンズ挿入器具の練習用キット２０００を構成することで、練習者は、レンズ射出挙動不全となる場合の眼内レンズ挿入器具２の挿入状態を把握することができる。 Thus, in this modification, by configuring the intraocular lens insertion device practice kit 2000 so that the intraocular lens insertion device 2 can be inserted not only into the insertion hole 2010h but also into the insertion hole 2011h, The practitioner can grasp the insertion state of the intraocular lens insertion device 2 when the lens ejection behavior is incomplete.
〔第３の変形例〕
　以下に、第３の変形例に係る眼内レンズ挿入器具の練習用キット３０００について説明する。本変形例の眼内レンズ挿入器具の練習用キット３０００は、第１の実施形態の眼内レンズ挿入器具の練習用キット１とは、Ｏリング２２の代わりにシリコーンシート３００１が用いられている点のみが異なり、それ以外は同じ構成を有する。 [Third Modification]
Below, the kit 3000 for practice of the intraocular lens insertion device which concerns on a 3rd modification is demonstrated. The practice kit 3000 for the intraocular lens insertion device of the present modification example is different from the practice kit 1 for the intraocular lens insertion device of the first embodiment in that a silicone sheet 3001 is used instead of the O-ring 22. The only other differences are the same.
　図１６に、本変形例に係る眼内レンズ挿入器具の練習用キット３０００の概略構成図を示す。図１６に示すように、眼内レンズ挿入器具の練習用キット３０００のシリコーンシート３００１にはシートの表裏を貫通する切り込み３００１ａが設けられている。切り込み３００１ａの幅は、第１の実施形態のＯリング２２の内径と同一である。また、切り込み３００１ａに眼内レンズ挿入器具が挿入されると、切り込み３００１ａは眼内レンズ挿入器具の外形に合わせて開口および変形する。 FIG. 16 shows a schematic configuration diagram of a practice kit 3000 for an intraocular lens insertion device according to this modification. As shown in FIG. 16, the silicone sheet 3001 of the practice kit 3000 for the intraocular lens insertion device is provided with a cut 3001a that penetrates the front and back of the sheet. The width of the notch 3001a is the same as the inner diameter of the O-ring 22 of the first embodiment. When the intraocular lens insertion instrument is inserted into the notch 3001a, the notch 3001a opens and deforms in accordance with the outer shape of the intraocular lens insertion instrument.
　上述した通り、実際の手術では、角膜、強角膜などに切り込み３００１ａと同様の切開創が設けられる。したがって、本変形例の眼内レンズ挿入器具の練習用キット３０００によれば、上記の実施形態および変形例のようにＯリングを使用する場合に比べて、より実際の手術に近い状況を想定した眼内レンズ挿入器具の挿入を疑似体験することが可能となる。 As described above, in actual surgery, an incision similar to the incision 3001a is provided in the cornea, cornea, and the like. Therefore, according to the practice kit 3000 for the intraocular lens insertion device of the present modification example, a situation closer to the actual operation is assumed compared to the case where the O-ring is used as in the above embodiment and modification examples. It becomes possible to simulate the insertion of the intraocular lens insertion device.
