Description

本発明は、巻き爪を生じた人の爪に取着して、巻き爪を矯正する巻き爪矯正具に関する。The present invention relates to an incurvated nail correction tool that is attached to a nail of a person who has an ingrown nail and corrects the ingrown nail.

巻き爪とは、その発症例の多くは第一趾爪縁が内側に湾曲し、その変形が進行することで、爪縁部が爪郭といわれる爪溝の軟部組織に刺入し炎症を生じさせ、さらに症状を悪化させると該炎症部の腫脹が劈開を起こし、足を地面に接することができないほどの激痛によって歩行が困難になることさえある。巻き爪は成長し続けるので、早期に施術を講じる必要がある。なお治療には根治治療を目的とした外科的な施術と保存治療の矯正具によるものに大別されるが、巻き爪部を切除する外科的な施術の場合、再発した同じ爪を繰り返し施術すると爪の幅が極端に少なくなったり、また生えなくなったりしてしまうことさえあることから、矯正具によって治療する手段が現在は主流になりつつある。
巻き爪を治療する方法として種々の矯正具が発明されているが、その中でいくつかの矯正具を紹介すると、例えば矯正具本体が弾性材を用い成形され、該材料の性質である弾性復元力によって矯正を行うプレート（例えば、特許文献１参照。）や爪幅方向に長い矯正板と爪係止用のツメを形成することで該矯正具本体の弾性復元力で矯正する矯正具（例えば、特許文献２参照。）、弾性効果を有する形状記憶樹脂材や形状記憶合金を用いたプレート（例えば、特許文献３参照。）、弾性ワイヤーを爪の両側へ引っ掛けて張力を用いた矯正方法（例えば実案文献１参照。）など、巻き爪の湾曲する成長方向に対して、該巻き爪を修復する矯正方向に矯正体の弾性復元力の作用を用いて矯正する矯正具が開示されている。
その他の矯正具の矯正方法は爪縁に取着する手法で、例えば巻き爪を発症している爪縁部の爪先端部から爪根に向かって差込み取着させた矯正具を矯正方向に回転させる矯正法（例えば、特許文献４参照。）は爪床から離れているわずかな爪縁に引っ掛け回転させるため、矯正が働く箇所が小さく矯正力が爪縁に集中することで爪を劈開したり、生爪を剥いだりしやすくなる欠点がある。その他には、両側の爪縁に矯正体のツメを取着させ矯正方向に引っ張る矯正具（例えば、特許文献５参照。）なども開示されている。

If the symptoms worsen further, the swelling of the inflamed part may cause cleaving, and walking may be difficult due to severe pain that the foot cannot touch the ground. As curly nails continue to grow, it is necessary to take treatment early. Treatment is roughly divided into surgical treatment for the purpose of curative treatment and conservative treatment correction tools, but in the case of surgical treatment to remove the ingrown nail part, repeated reapplying the same nail Since the width of the nail may become extremely small or even no longer grow, the means of treating with a corrector is now becoming mainstream.
Various correction tools have been invented as a method for treating curled nails, and some of the correction tools are introduced. For example, the correction tool body is molded using an elastic material, and the elastic restoration is a property of the material. A correction tool that corrects with the elastic restoring force of the correction tool body by forming a plate that corrects by force (for example, see Patent Document 1), a correction plate that is long in the nail width direction, and a claw for locking the nail. , See Patent Document 2), a plate using a shape memory resin material or shape memory alloy having an elastic effect (see, for example, Patent Document 3), a correction method using tension by hooking an elastic wire on both sides of the nail ( For example, refer to Model Literature 1), and a correction tool that corrects the curled nail in the correction direction by using the elastic restoring force of the correcting body in the correction direction for repairing the curled nail is disclosed. .
Other orthodontic tools are attached to the nail edges, for example, the corrective tool inserted and attached from the tip of the nail edge where the nail has developed to the nail root is rotated in the correction direction. The correction method (see, for example, Patent Document 4) is hooked and rotated on a slight nail edge away from the nail bed, so that the area where the correction works is small and the correction force concentrates on the nail edge, thereby cleaving the nail. , There is a drawback that it is easy to peel off the raw nails. In addition, a correction tool (see, for example, Patent Document 5) that attaches the tabs of the correction body to the nail edges on both sides and pulls the correction body in the correction direction is also disclosed.

しかし、このような従来の巻き爪用の矯正具、例えば弾性復元力を用いた矯正手段は種々の矯正具の取着方法に違いはあるが、矯正具本体の弾性復元力の作用により巻き爪を徐々に平状へ復元して行く手段は同じであり、常に巻き爪患部の湾曲状の爪へ矯正力が働き変形を求めていることから、巻き爪形状から健常な爪形に修復する手法ではなく、巻き爪の痛みから解放する手段であることは明らかである。この根拠を補強する文献は、青木文彦氏による第４５回日本形成外科学会学術集会にて講演発表された内容（２００２年４月１９日）からも推察できる。同文献では、巻き爪の症状や爪質にもよるが、弾性作用を用いた矯正具の治療期間は早くて２週間、爪基部まで平坦化するのには通常６カ月〜１年を要すると発表されていることからもわかる。即ち、足の親指の爪の長さは略１８ｍｍであり、伸びる速度は一日略０．１ｍｍは定説となっていることから、６ヶ月の１８２日で１８．２ｍｍ、１年の３６５日で３６．５ｍｍと弾性復元力を用いた矯正治療において完治する期間をみると略新しい爪に生え変わっているのである。なお、別の矯正具では被験者１０名に弾性作用の矯正具で治療されたが、早い者で３日程度で効果がみられ、２週間経過時点で略全員巻き爪が解消されたとされているが、個々の巻き爪の症状が不明であるため精度は不明確である（特許文献６参照。）。
特開２００７−２４４８５１号公報６頁段落番号００２８ However, there are differences in the conventional corrective tools for ingrown nails, for example, the corrective means using elastic restoring force, but there are differences in the attachment method of various corrective tools. The method of gradually restoring to a flat shape is the same, and since the correction force always works on the curved nail of the affected area of the nail and seeks deformation, a method to restore from the nail shape to a healthy nail shape It is clear that it is a means to relieve the pain of the nail. The literature that reinforces this ground can also be inferred from the contents (April 19, 2002) presented at the 45th Annual Meeting of the Japanese Plastic Surgery Society by Fumihiko Aoki. According to this document, although it depends on the nail symptom and nail quality, the treatment period of the correction tool using the elastic action is 2 weeks at the earliest, and it usually takes 6 months to 1 year to flatten to the nail base. It can also be seen from the announcement. That is, the length of the toenails is about 18 mm, and the rate of extension is about 0.1 mm per day, so it has been 182 days in 6 months, 18.2 mm in 1 month, 365 days in 1 year In terms of 36.5 mm, the period of complete cure in the orthodontic treatment using elastic restoring force, the nail is reborn as a nearly new nail. In the case of another corrective tool, 10 subjects were treated with an elastic corrective tool, but the effect was seen in about 3 days in early subjects, and almost all wound nails were resolved after 2 weeks. However, the accuracy is unclear because the symptoms of the individual nail are unknown (see Patent Document 6).

また、弾性材もしくは形状記憶材を用いて形成した矯正作用体を湾曲状に変形させて爪甲部へ密着固定、いわゆる矯正作用体全体を固着した場合、この矯正具自体の伸縮変形がない限りは巻き爪の湾曲状は固定され、矯正力は無力な状態になり、湾曲が進行し悪化することも無いが、矯正されることもないと思われる。In addition, if the corrective action body formed using an elastic material or shape memory material is deformed into a curved shape and closely fixed to the nail plate, so-called corrective action body as a whole is fixed, as long as there is no expansion / contraction deformation of the corrective tool itself The curving shape of the wound nail is fixed, the correction force becomes ineffective, the bending does not progress and does not deteriorate, but it seems that it is not corrected.

そこで、本発明は前記事情に基づいて成されたもので、弾性復元力の作用による矯正力を用いず、矯正中の巻き爪を矯正形状で固定保持できる剛性材または剛性構造で矯正作用体を形成することで、安静状態で矯正治療が行える巻き爪矯正具の提供を課題とする。Therefore, the present invention has been made based on the above circumstances, and does not use the correction force due to the action of the elastic restoring force, and the correction action body is made of a rigid material or structure that can fix and hold the wound nail being corrected in a corrected shape. An object of the present invention is to provide an ingrown nail correction tool that can be corrected in a resting state.

上記の課題を解決するために、爪形を所望の形状で固定するには、先ず爪形を変形できる状態に緩めたら、爪形を所望の形状で保持し、後に爪形を固定化すると、矯正具を外した後もその形状は維持されるのである。これを利用し本発明の巻き爪矯正具により矯正治療を施すのである。
巻き爪の形成に関与しているのは、ポリペプチド側鎖結合の結合組織であることは既知である。第一趾の該ポリペプチド側鎖結合が何らかの原因で歪み、湾曲状に変形したことは、巻き爪の湾曲状が固定化し形成されていたり、該歪みが進行し形状が悪化したりすることからも推察できる。このように、爪の組成に関わるポリペプチド側鎖結合の歪みを除去しないまま矯正治療を行っても、巻き爪の早期再発の蓋然性は高いと思われる。In order to solve the above problem, to fix the nail shape in a desired shape, first loosen the nail shape so that it can be deformed, hold the nail shape in the desired shape, and then fix the nail shape later, Even after the corrector is removed, its shape is maintained. Using this, the orthodontic treatment is performed by the ingrown nail correction tool of the present invention.
It is known that it is the connective tissue of the polypeptide side chain that is involved in the formation of the claw. The fact that the side chain bond of the polypeptide of the first cage is distorted and deformed due to some reason is because the curved shape of the wound nail is fixed and formed, or the distortion progresses and the shape deteriorates Can also be guessed. Thus, even if orthodontic treatment is performed without removing the distortion of the polypeptide side chain bonds related to the composition of the nail, the probability of early recurrence of the wound nail seems to be high.

そこで、該ポリペプチド側鎖結合の歪みを取り除き巻き爪の形状を修復するには、変性剤を巻き爪部へ含侵させるかまたは変性が起こる環境下で該ポリペプチド側鎖結合の結合を緩めることで固定化されていた巻き爪形状を解いた後、直ちに巻き爪を修復する爪形即ち略平状の爪形で固定保持された安静環境の状態にし、変性している爪部へ再架橋剤を含侵させるかまたは再架橋が起こる環境下において該ポリペプチド側鎖結合を再架橋することで、巻き爪の湾曲状は略平状へと再固定化し、修復される。この再架橋には平温時で１０分から２０分で完了するが、他の再架橋の確認方法は反対側の第一趾の爪と同程度の硬度に戻ったことで完了したことが確認できる。この施術の際、爪形が変動するような矯正具を用いて不安定な保持をした場合など、爪形を予期しない形状で固定してしまうことがある。該巻き爪を施術者の所望する矯正形状で固定保持し、安静状態が保てる環境下で矯正治療することが必要である。Therefore, in order to remove the distortion of the polypeptide side chain bond and restore the shape of the wound nail, the denaturing agent is impregnated into the nail part or the polypeptide side chain bond is loosened in an environment where denaturation occurs. After unwinding the wound nail shape, the nail shape that repairs the wound nail immediately, that is, the nail shape that is fixed and held in a flat nail shape, is re-crosslinked to the denatured nail portion By re-crosslinking the polypeptide side-chain bond in an environment where the agent is impregnated or re-crosslinking occurs, the curved shape of the nail is re-fixed to a substantially flat shape and repaired. This re-crosslinking is completed in 10 to 20 minutes at normal temperature, but it can be confirmed that the other re-crosslinking confirmation methods have been completed by returning to the same degree of hardness as the nail of the first hook on the opposite side. . During this operation, the nail shape may be fixed in an unexpected shape, for example, when the nail shape is unstablely held using a correction tool that changes the nail shape. It is necessary to fix and hold the wound nail in the correct shape desired by the practitioner and corrective treatment in an environment where a resting state can be maintained.

請求項１の発明の巻き爪矯正具は、人の爪に発症している巻き爪の正面先端部から取着して該巻き爪の矯正をする矯正作用体において、結合部を介在し上下に配置された矯正板は、爪幅方向に長く、且つ該巻き爪の復元力に対して爪形を略平状に固定し保持できる硬度に強化された剛性材または剛性構造で形成され、この該矯正板と該結合部とで断面略コ字状に矯正作用体を形成し、上下の該矯正板が対向し形成する矯正用間隙へ該巻き爪の正面先端部を挿入することによって、該巻き爪を矯正する方向へ略平状に固定保持した安静状態で矯正できることを特徴とする。The ingrown nail correction tool according to the first aspect of the present invention is a correction body that is attached from the front end of the ingrown nail that develops on a human nail and corrects the ingrown nail. The arranged correction plate is formed of a rigid material or a rigid structure that is long in the width direction of the nail and has a hardness that can fix and hold the nail shape substantially flat against the restoring force of the wound nail. A straightening action body having a substantially U-shaped cross section is formed by the straightening plate and the coupling portion, and the front end of the wound nail is inserted into a straightening gap formed by the upper and lower straightening plates facing each other. It is characterized in that it can be corrected in a resting state in which the nail is fixed and held in a substantially flat shape.

請求項２の発明の巻き爪矯正具は、人の爪に発症している巻き爪の正面先端部から該巻き爪部へ挟着して該巻き爪の矯正をする矯正作用体において、該巻き爪を矯正する方向へ略平状に形成し保持できる挟圧力を発生させる弾性作用を結合部へ具備することによって、爪厚の個体差に対応し、且つ該巻き爪を略平状に固定保持した安静状態で矯正できることを特徴とする。The ingrown nail correction tool of the invention of claim 2 is an orthodontic action body that corrects the ingrown nail by pinching the ingrown nail from the front end of the ingrown nail to the ingrown nail. Responding to individual differences in nail thickness by fixing the nail thickness in an approximately flat manner by providing the joint with an elastic action that generates a pinching force that can be formed and held in a substantially flat shape in the direction of correcting the nail. It can be corrected in a resting state.

請求項３の発明の巻き爪矯正具は、巻き爪を発症した人の爪の該巻き爪甲部へ取着して該巻き爪の矯正をする矯正作用体において、該巻き爪を略平状に矯正する方向で固定し、保持できる硬度に強化された剛性材を用いて爪幅方向に長く形成された矯正板を爪甲部へ取着することによって、該巻き爪を略平状に安静状態で固定保持して矯正できることを特徴とする。According to a third aspect of the present invention, there is provided a corrective nail corrector which is attached to the ingrown nail portion of a nail of a person who has developed an ingrown nail and corrects the ingrown nail. By attaching a straightening plate, which is formed long in the nail width direction, to the nail plate using a rigid material strengthened to a hardness that can be fixed and held in the nail plate, the wound nail is rested in a substantially flat shape. It is characterized in that it can be fixed and held in a state to correct.

前記請求項１および請求項２および請求項３の発明の構成によれば、従来の矯正具の特徴である弾性復元力の作用を用いた矯正手段ではなく、巻き爪を略平状に固定できる剛性材または剛性構造で形成された矯正板または矯正具本体を用いることで該巻き爪を矯正形状で固定し、安静状態を保持することで、爪の形状に関与するポリペプチド側鎖結合の歪みを効果的に修復し、整えることで、爪の復元を充分発揮できる剛性材または剛性構造で矯正用体を形成している。According to the first, second and third aspects of the invention, the wound nail can be fixed in a substantially flat shape instead of the correction means using the action of the elastic restoring force, which is a characteristic of the conventional correction tool. Distortion of polypeptide side chain bonds involved in the shape of the nail by fixing the wound nail in a corrected shape by using a correction plate or a correction tool body formed of a rigid material or a rigid structure and maintaining a resting state By effectively repairing and arranging the nail, the correction body is formed of a rigid material or a rigid structure that can sufficiently exhibit the restoration of the nail.

以上説明したように請求項１および請求項２および請求項３の発明の巻き爪矯正具によれば、従来の弾性材を用いて形成された矯正具の弾性復元力による矯正作用とは異なり、巻き爪の形成に影響を与えていた、爪の組成に関与するポリペプチド側鎖結合の歪みを修復するとともに、矯正治療中に靴や靴下などの外圧により起こる爪の変形を予防するためにも、該巻き爪を矯正形状で固定保持することで安静状態を確保した環境下で矯正治療が行えることを目的とした、矯正作用体の作用を充分発揮できる剛性材または剛性構造で形成される。As described above, according to the wound nail correction tool of the invention of claim 1, claim 2 and claim 3, unlike the correction action by the elastic restoring force of the correction tool formed using the conventional elastic material, In addition to repairing the distortion of polypeptide side chain bonds involved in nail composition that had affected the formation of wound nails, and also to prevent nail deformation caused by external pressure from shoes and socks during orthodontic treatment The rigid nail is made of a rigid material or a rigid structure capable of sufficiently exerting the action of the corrective body for the purpose of performing orthodontic treatment in an environment in which a resting state is secured by fixing and holding the curled nail in a straightened shape.

また、請求項２の発明の巻き爪矯正具によれば、矯正作用体の矯正作用は剛性材または剛性構造により形成された上下の矯正板を該巻き爪の正面先端部へ取着することによって該巻き爪を矯正形状で固定し安静保持を得るのは請求項１と同様であるが、矯正板の結合部に弾性作用を発生させる弾性構造または弾性材を具備することで矯正作用も強化することができ、夫々の巻き爪の症状に対応できる能力が拡大すると共に、矯正具の矯正用間隙の開閉能が得られることで種々の爪厚にも対応が可能となる。また、挟着作業も容易となる。このことにより種々の巻き爪に対し、矯正作用体の作用を充分に発揮できる。Further, according to the ingrown nail correction tool of the invention of claim 2, the correcting action of the correcting body is performed by attaching the upper and lower correction plates formed of a rigid material or a rigid structure to the front end portion of the ingrown nail. It is the same as in claim 1 to fix the wound nail in a straightened shape to obtain a rest, but the straightening action is also strengthened by providing an elastic structure or elastic material that generates an elastic action at the joint of the straightening plates. In addition, the ability to cope with the symptoms of each nail is expanded, and the ability to open and close the correction gap of the correction tool can be obtained, thereby making it possible to cope with various nail thicknesses. Moreover, the clamping work is also facilitated. As a result, the action of the correcting body can be sufficiently exerted on various wound nails.

また、請求項３の発明の巻き爪矯正具によれば、矯正作用体は剛性材または剛性構造で略板状に形成されている。このため、巻き爪の正面先端部が伸びていないことで請求項１および請求項２の巻き爪矯正具の装着が困難な場合であっても、該矯正作用体を、巻き爪を発症している爪甲部へ接着剤または両面接着テープを用いて固着することで、該巻き爪の爪形を略平状に固定保持できることにより、矯正作用である安静保持の環境状態で爪形を固定できる構造で形成されるので、矯正作用体の作用を充分発揮できる。According to the wound nail correction tool of the invention of claim 3, the correction acting body is formed in a substantially plate shape with a rigid material or a rigid structure. For this reason, even if it is difficult to wear the ingrown nail corrector according to claim 1 or 2 because the front end portion of the ingrown nail is not extended, The nail shape of the wound nail can be fixed and held in a substantially flat shape by fixing it to the nail plate portion using an adhesive or a double-sided adhesive tape, so that the nail shape can be fixed in an environmental state of resting as a correction action. Since it is formed with a structure, the action of the corrective action body can be sufficiently exerted.

発明を実施するため最良の形態BEST MODE FOR CARRYING OUT THE INVENTION

本願の請求項１の発明にかかわる第一の実施の形態について、図１ないし図２を参照して説明する。この実施の形態は人の第一趾の爪縁に生じた巻き爪を矯正する矯正具を対象にしている。A first embodiment according to the first aspect of the present invention will be described with reference to FIGS. This embodiment is directed to a correction tool that corrects a wound nail generated on the nail edge of a person's first eyelid.

図２（ａ）において、２１は第一趾の左爪縁に発生した巻き爪、２２は正面先端部、２３は爪縁部、２４は爪郭である。図１は本願発明の第一の実施の形態である巻き爪矯正具Ｋａを示している。該巻き爪矯正具Ｋａは挟持用の矯正用間隙４を具備した断面略コの字状を成すもので、この巻き爪矯正具Ｋａは図２（ｂ）に示すように矯正すべき第一趾に発症した巻き爪２１の湾曲した爪幅方向の寸法と爪厚を考慮して該巻き爪矯正具Ｋａの寸法は決められるが、該巻き爪矯正具Ｋａは湾曲状の爪幅の略２倍程度、矯正用間隙４は爪厚より＋０．１ｍｍ〜０．３ｍｍ程度広くとると良い。例えば巻き爪矯正具Ｋａは外寸幅１２ｍｍ程度、外奥行き５ｍｍ程度、外丈３ｍｍ程度の断面略コの字状に外形は形成され、結合部１から延びる上側の矯正板２は幅１２ｍｍ程度、内奥行き４ｍｍ程度、厚さ１ｍｍ程度の板状で、下側の矯正板３は幅１２ｍｍ程度、内奥行き４ｍｍ程度、厚さ１ｍｍ程度の板状で、矯正用間隙４の開口部の高さは１ｍｍ程度で夫々は形成されている。In FIG. 2 (a), 21 is a winding nail generated on the left nail edge of the first heel, 22 is a front end portion, 23 is a nail edge portion, and 24 is a nail contour. FIG. 1 shows an incurvated nail corrector Ka that is a first embodiment of the present invention. The incurvated nail correction tool Ka has a substantially U-shaped cross section with a correction gap 4 for clamping, and the ingrown nail correction tool Ka is a first hook to be corrected as shown in FIG. The dimensions of the curly nail corrector Ka are determined in consideration of the curved nail width dimension and the nail thickness of the curly nail 21 developed in the above, but the curl nail corrector Ka is approximately twice the curved nail width. The correction gap 4 should be about +0.1 mm to 0.3 mm wider than the nail thickness. For example, the curly nail correction tool Ka has an outer shape with an outer width of about 12 mm, an outer depth of about 5 mm, and an outer height of about 3 mm, and the upper correction plate 2 extending from the coupling portion 1 has a width of about 12 mm. The lower correction plate 3 is a plate having an inner depth of about 4 mm and a thickness of about 1 mm. The lower correction plate 3 is a plate having a width of about 12 mm, an inner depth of about 4 mm and a thickness of about 1 mm, and the height of the opening of the correction gap 4 is Each is formed in about 1 mm.

この巻き爪矯正具Ｋａは図２（ｂ）に示すように巻き爪２１を略平状で固定し且つ保持できる強度がある剛性材または剛性構造、例えば硬質ポリエチレン系の高分子樹脂材で形成されている。高分子樹脂では、硬質ポリプロピレンやＰＥＴなどに代表される熱可塑性樹脂、フェノール樹脂やメラミン樹脂などに代表される熱硬化性樹脂などが挙げられる。また、金属では、Ｆｅ、Ｃｕ、Ｔｉ、Ａｌ、ＳＵＳ、Ａｇなどの１種または２種以上を含んだ合金で形成されてもよい。As shown in FIG. 2B, the ingrown nail correction tool Ka is formed of a rigid material or a rigid structure that can fix and hold the ingrown nail 21 in a substantially flat shape, for example, a hard polyethylene polymer resin material. ing. Examples of the polymer resin include thermoplastic resins typified by hard polypropylene and PET, and thermosetting resins typified by phenol resin and melamine resin. Further, the metal may be formed of an alloy containing one or more of Fe, Cu, Ti, Al, SUS, Ag, and the like.

該巻き爪矯正具Ｋａを第一趾の巻き爪２１に取着し矯正する手法の一例を示すが、これに限定されるものではない。例えば、先ずポリペプチド側鎖結合を変性させるため、少なくとも第一趾を４０℃〜４５℃の温水に１５分程度の時間は浸し、指で該巻き爪２１に触って充分柔らかく該ポリペプチド側鎖結合が緩みふやけたことを確認できたら、図２（ｂ）に示すように該巻き爪２１の正面先端部２２へ巻き爪矯正具Ｋａを挟着させる。この際、該巻き爪矯正具Ｋａが容易に外れないように爪や人体に悪影響を与えない接着剤またはテープを用いて固着してもよい。Although an example of a method for attaching and correcting the curled nail correction tool Ka to the curled nail 21 of the first hook is shown, it is not limited to this. For example, first, in order to denature the polypeptide side chain bond, at least the first cocoon is immersed in warm water of 40 ° C. to 45 ° C. for about 15 minutes, and touches the curled nail 21 with a finger to make the polypeptide side chain soft enough. When it is confirmed that the connection has been loosened and loosened, the wound nail corrector Ka is sandwiched between the front end 22 of the wound nail 21 as shown in FIG. At this time, an adhesive or a tape that does not adversely affect the nails and the human body may be fixed so that the curled nail correction tool Ka does not easily come off.

そうすると、該巻き爪２１を略平状へ固定できる巻き爪矯正具Ｋａによって安静状態が確保された環境下で、温水を含侵して変性していた巻き爪２１の該ポリペプチド側鎖結合が徐々に乾燥するとともに再結合が進行し、さらに巻き爪２１が通常の爪硬度まで乾燥した状態に達した時、巻き爪が発症していた爪の形状は略平状の矯正形状で固定化し、修復される。なお、巻き爪の症状により再架橋の回数や矯正具の装着時間は適宜に増減されてもよい。Then, in an environment in which a resting state is secured by the curly nail correction tool Ka that can fix the curly nail 21 to a substantially flat shape, the polypeptide side chain bond of the curly nail 21 that has been denatured by impregnation with warm water is gradually increased. When the nail 21 is dried to the normal nail hardness and the nail 21 has reached the normal nail hardness, the nail shape in which the nail has developed is fixed in a substantially flat correction shape and repaired. Is done. Note that the number of re-crosslinking and the wearing time of the correction tool may be appropriately increased or decreased depending on the symptoms of the wound nail.

このように該ポリペプチド側鎖結合が再結合された段階で爪形は固定化されてしまうため、該巻き爪２１は略平状の矯正形状でしっかりと固定保持され、安静状態で長時間保持できる矯正治療の環境下で治療をおこなうことで、施術者の所望する修復形状が確保できるのである。だが、矯正時に弾性復元力を常に爪へ働かせる弾性作用の矯正具のように、爪形の変動を強要する不安定な治療法では修復後の爪形を施術者の所望で固定化することは困難である。また、爪が蒸れる原因である高温多湿の環境を提供する靴や靴下などは特に足の爪の該ポリペプチド側鎖結合が変性しやすく、しかも第一趾の爪縁に接触圧力を掛ける締め付けの強い形状の靴や靴下であったりする場合には、該弾性能矯正具ともども変形させて、湾曲状をさらに進行させてしまう場合があるが、該巻き爪矯正具Ｋａの上下の矯正板２、３は剛性材を用いて形成しているため、巻き爪矯正具Ｋａに挟着された該巻き爪２１は接触圧力にも安静状態は確保され、巻き爪の悪化を促進していた靴や靴下の環境下での該巻き爪矯正具Ｋａの使用はむしろ該ポリペプチド側鎖結合の再結合による巻き爪の修復を効果的に発揮する働きに利用することができる。Since the nail shape is fixed when the polypeptide side chain bond is recombined in this way, the wound nail 21 is firmly fixed and held in a substantially flat correction shape, and held in a resting state for a long time. By performing treatment in an environment of corrective treatment that can be performed, the repaired shape desired by the practitioner can be secured. However, like an elastic correction tool that always applies elastic restoring force to the nail during correction, it is impossible to fix the nail shape after the repair as desired by the practitioner in an unstable treatment method that requires fluctuations in the nail shape. Have difficulty. Also, shoes and socks that provide a hot and humid environment that causes the nails to damp are particularly susceptible to denaturation of the polypeptide side chain bonds of the toenails, and tightening that applies contact pressure to the nail edges of the first heel. In the case of strong shoes or socks, the elastic performance corrector may be deformed and the curved shape may be further advanced, but the correction plates 2 above and below the curly nail corrector Ka, 3 is made of a rigid material, so that the wound nail 21 sandwiched between the curly nail correction tools Ka is kept in a resting state against contact pressure, and shoes and socks that have promoted the deterioration of the wound nail.
