Description

本発明は、陥入爪や巻き爪を矯正するための陥入爪矯正具に関する。 The present invention, ingrown nail correction for correcting ingrown nails and pincer nail again and again relates.

陥入爪は、爪の側縁が内側に巻き込むように屈曲して軟質組織（足指の肉など）を圧迫、あるいは、軟質組織に刺さって炎症を起こす疾患であって、苦痛を与えるほか、肉芽を発生させたり、化膿させるなどの症状を引き起こすことがある。ちなみに、巻き爪とは、爪の側縁が内側に巻き込んでいる状態を呼ぶが、陥入爪の人は巻き爪になっていることが多い。 An ingrown nail is a disease that causes the side edges of the nail to bend inward and compresses soft tissue (such as the flesh of the toes) or pierces the soft tissue and causes inflammation. May cause symptoms such as granulation and suppuration. Incidentally, the term “claw claw” refers to a state in which the side edge of the claw is wound inside, but a person with an ingrown claw often has a claw.

従来、このような巻き爪を含む陥入爪を矯正するための矯正具が提案されている。
たとえば、形状記憶合金や形状記憶樹脂を用いて形成した板状体またはテープ状体に、予め正常な爪の形状を所定温度で記憶させておき、その板状体またはテープ状体を接着剤で陥入爪に貼り付けるようにした矯正具が提案されている（特許文献１，特許文献２および特許文献３参照）。 Conventionally, a correction tool for correcting an ingrown nail including such a wound nail has been proposed.
For example, a normal shape of a nail is stored in advance at a predetermined temperature in a plate or tape formed using a shape memory alloy or shape memory resin, and the plate or tape is then bonded with an adhesive. An orthodontic tool that is attached to an ingrown nail has been proposed (see Patent Literature 1, Patent Literature 2 and Patent Literature 3).

しかしながら、上述した矯正具では、板状体などを爪に貼り付ける際、強力な接着剤を必要とし、接着剤の乾燥にも時間がかかり、その間ピンセットなどで抑えていなければならないなど、取り扱いが面倒である。また、接着剤が爪以外の皮膚などに付着すると、皮膚が炎症を起こしたり、剥がれるなど外傷を起こしやすいという課題がある。 However, the above-mentioned correction tool requires a strong adhesive when sticking a plate or the like to the nail, and it takes time to dry the adhesive, and during that time it must be suppressed with tweezers etc. It is troublesome. In addition, when the adhesive adheres to the skin other than the nail, there is a problem that the skin is easily inflamed or peeled off.

そこで、本出願人は、先に、これらの課題を解決した陥入爪矯正具を提案した（特許文献４参照）。
これは、上下に間隔をあけて設けられその間にコ字状空間を形成する上下挟持片と、上挟持片の上部に一体的に形成された連結孔を有する連結部とから構成されている。上下挟持片のうち、上挟持片が下挟持片よりも長く形成されている。 Therefore, the present applicant has previously proposed an ingrown nail correction tool that solves these problems (see Patent Document 4).
This is composed of an upper and lower clamping piece which is provided at an interval in the vertical direction and forms a U-shaped space therebetween, and a connecting portion having a connecting hole integrally formed on the upper portion of the upper clamping piece. Of the upper and lower clamping pieces, the upper clamping piece is formed longer than the lower clamping piece.

使用にあたっては、上述した構造の矯正具を一対用意し、各矯正具の上下挟持片を、爪の側縁に嵌め込む。つまり、爪の側縁が露出するように、その近傍の指肉を切開し、露出した爪の側縁と指肉との間に下挟持片を差し込む。続いて、糸を、両側の矯正具の連結孔に通し、両側の矯正具が互いに接近するように糸を緊張させたのち、その両端を結ぶ。これにより、爪の両側縁に対して常時上方への引き上げ力が作用するため、陥入爪に対する矯正効果が期待できる。 In use, a pair of correction tools having the structure described above is prepared, and the upper and lower clamping pieces of each correction tool are fitted into the side edges of the nails. That is, the finger meat near the nail is cut open so that the side edge of the nail is exposed, and the lower holding piece is inserted between the exposed side edge of the nail and the finger meat. Subsequently, the thread is passed through the connecting holes of the correction tools on both sides, and after tensioning the yarn so that the correction tools on both sides approach each other, the ends are tied. Thereby, since the upward pulling force always acts on both side edges of the nail, a correction effect on the ingrown nail can be expected.

しかしながら、本出願人が先に提案した陥入爪矯正具も、更に、次のような課題が考えられる。
（ａ）爪への取り付けに際して、接着剤を用いていないので、剥離や取り替えの手間がかかることがないが、爪の側縁が露出するように、その近傍の指肉を切開し、露出した爪の側縁と指肉との間に下挟持片を差し込む必要があるので、取り付けが困難である。
（ｂ）陥入爪に矯正具が取り付けられた状態では、矯正具の連結部が爪の両側縁から上方に突出し、かつ、その両側の矯正具を結ぶ糸が爪の甲の上に露出しているため、これらが衣類、例えば、靴下などに引っ掛かりやすい。
（ｃ）陥入爪に対する矯正効果は、両側の矯正具を結ぶ糸の緊張度合いを調整しなければならないため、微調整が難しい。 However, the ingrown nail correction tool previously proposed by the present applicant may also have the following problems.
(A) Since no adhesive is used when attaching to the nail, there is no need for peeling or replacement, but the finger skin in the vicinity of the nail is opened and exposed so that the side edges of the nail are exposed. Since it is necessary to insert a lower clamping piece between the side edge of the nail and the finger meat, the attachment is difficult.
(B) In a state where the correction tool is attached to the ingrown nail, the connecting portion of the correction tool protrudes upward from the both side edges of the nail, and the thread connecting the correction tools on both sides is exposed on the back of the nail. Therefore, they are easily caught on clothes such as socks.
(C) The correction effect on the ingrown nail is difficult to finely adjust because the degree of tension of the thread connecting the correction tools on both sides must be adjusted.

本発明の目的は、これらの課題を解決し、爪への取り付けが簡単で、取り付けられた状態では、衣類などに引っ掛かる虞も少なく、かつ、矯正作用も適切な力で持続的に行うことが可能な陥入爪矯正具を提供することにある。 The object of the present invention is to solve these problems, easy to attach to the nail, and in the attached state, there is little risk of getting caught on clothes etc., and the corrective action can be continuously performed with an appropriate force. It is to provide a possible ingrown nail corrector.

本発明の陥入爪矯正具は、弾性を有する材料によって板状に形成された板状体と、この板状体に間隔を隔てて設けられ爪の先端縁に差し込まれ前記爪を挟持する少なくとも２以上の挟持部と、前記板状体の両端側に設けられ前記板状体を爪に接着固定するための接着剤塗布用孔とを備えたことを特徴とする。
ここで、板状体を形成する材料としては、弾性を有する材料であれば、どのようなものでもよい。例えば、ステンレスや樹脂などでもよく、あるいは、超弾性材料、形状記憶合金材料などでもよい。 The ingrown nail corrector according to the present invention includes a plate-like body formed into a plate shape by an elastic material, and is provided at an interval to the plate-like body and is inserted into a tip edge of the nail to sandwich the nail. and two or more holding portions, characterized in that the plate-like body provided at both ends of the plate-like body with an adhesive coating hole for adhering and fixing to the nail.
Here, the material for forming the plate-like body may be any material as long as it has elasticity. For example, stainless steel or resin may be used, or a superelastic material, a shape memory alloy material, or the like may be used.

この発明によれば、板状体に設けられた２以上の挟持部を、爪の先端縁に差し込むと、これらの挟持部が爪の先端を挟持するため、爪への取り付けが簡単に行え、しかも、取り外しも、爪から挟持部を引き抜くだけでよいから、取り外しも簡単にできる。
また、取り付けられた状態では、２以上の挟持部が爪の先端縁を挟持し、板状体が爪の甲に沿って取り付けられた状態であるから、衣類などに引っ掛かる虞も少ない。
また、板状体は、弾性を有する材料によって形成されているから、爪に取り付けられた状態では、２以上の挟持部によって、爪の先端縁両側が引き上げられる方向、つまり、陥入爪の両側縁が矯正される方向へ力が与えられるため、適切な力で持続的に矯正を行うことができる。
さらに、板状体の両端側には接着剤塗布用孔がそれぞれ設けられているから、この接着剤塗布用孔に接着剤を塗布して、板状体を爪に接着固定すれば、板状体の基端部分が爪の甲から浮くような現象を防ぐことができる。
なお、ここで言う陥入爪、および、以下で説明する陥入爪とは、巻き爪を含む意味である。 According to the present invention, when two or more sandwiching portions provided on the plate-like body are inserted into the tip edge of the nail, these sandwiching portions sandwich the tip of the nail, so that the attachment to the nail can be easily performed. In addition, the removal can be easily performed because it is only necessary to pull out the clamping part from the nail.
Further, in the attached state, two or more clamping portions sandwich the tip edge of the nail and the plate-like body is attached along the back of the nail, so that there is little possibility of being caught by clothing or the like.
In addition, since the plate-like body is formed of an elastic material, when attached to the nail, the direction in which both ends of the tip edge of the nail are pulled up by two or more clamping portions, that is, both sides of the ingrown nail Since force is applied in a direction in which the edge is corrected, correction can be performed continuously with an appropriate force.
Furthermore, since the adhesive application holes are provided on both ends of the plate-like body, if the adhesive is applied to the adhesive application holes and the plate-like body is adhered and fixed to the nails, the plate-like body The phenomenon that the base end of the body floats off the nail plate can be prevented.
In addition, the ingrown nail and the ingrown nail described below mean to include a wound nail.

本発明の陥入爪矯正具において、前記挟持部は、前記板状体の先端縁から前方へ向かって一体的に延長された上挟持片と、この上挟持片の先端から裏面側に屈曲され上挟持片との間に差込隙間を有する下挟持片とを含んで構成されていることが好ましい。
この発明によれば、板状体の先端縁から上挟持片を前方へ向かって一体的に延長し、この上挟持片の先端から下挟持片を裏面側に屈曲することによって、挟持部を構成できるため、つまり、１枚の板材を打ち抜き加工したのち、上挟持片および下挟持片を屈曲させるだけで構成することができるから、製造が簡単である。 In the ingrown nail correction tool of the present invention, the clamping part is bent from the front end edge of the plate-like body integrally toward the front, and from the front end to the back side of the upper clamping piece. It is preferable to include a lower holding piece having an insertion gap between the upper holding piece and the upper holding piece.
According to this invention, the upper holding piece is integrally extended forward from the front end edge of the plate-like body, and the holding portion is configured by bending the lower holding piece from the front end of the upper holding piece to the back surface side. In other words, since the sheet can be formed by punching a single plate material and then bending the upper and lower holding pieces, the manufacturing is simple.

本発明の陥入爪矯正具において、前記挟持部は、前記板状体に間隔を隔てて２つ設けられ、これら２つの挟持部は、前記板状体の先端縁から前方へ向かうに従って互いに離れる方向へ拡開されていることが好ましい。
この発明によれば、２つの挟持部が、板状体の先端縁から前方へ向かうに従って互いに離れる方向へ拡開されているから、爪から外れにくい効果がある。 In the ingrown nail corrector according to the present invention, two of the sandwiching portions are provided on the plate-like body with a space therebetween, and these two sandwiching portions are separated from each other as they move forward from the front edge of the plate-like body. It is preferably expanded in the direction.
According to this invention, since the two clamping portions are expanded in directions away from each other toward the front from the front end edge of the plate-like body, there is an effect that it is difficult to come off the nail.

本発明の陥入爪矯正具において、前記挟持部は、前記板状体の先端縁に切り起こし形成され板状体の裏面との間に差込隙間を有する切起片を含んで構成されていることが好ましい。
この発明によれば、板状体の先端縁に、例えば、コ字状の切り込みを形成し、この切り込みに囲まれた内側部分を板状体の裏面側へ屈曲させると、挟持部を構成できるため、つまり、１枚の板材に切り込みを入れたのち、その内側部分を切り起こすだけで構成できるから、製造が簡単である。しかも、この構成では、挟持部が板状体の輪郭部分より内側に形成されるため、衣類（靴下）などに挟持部が引っ掛かる虞がより少ない。 In the ingrown nail correction tool of the present invention, the clamping portion includes a cut and raised piece that is formed by cutting and raising at the leading edge of the plate-like body and having an insertion gap between the back surface of the plate-like body. Preferably it is.
According to the present invention, for example, a U-shaped cut is formed at the leading edge of the plate-like body, and the inner portion surrounded by the cut is bent toward the back side of the plate-like body, whereby the sandwiching portion can be configured. Therefore, since it can be configured by cutting and cutting the inner part after cutting a single plate material, manufacturing is simple. In addition, in this configuration, since the sandwiching portion is formed on the inner side of the contour portion of the plate-like body, there is less possibility that the sandwiching portion is caught on clothing (socks) or the like.

本発明の陥入爪矯正具において、前記板状体の基端側には、前記板状体を爪に固定するためのテープが掛けられるテープ用止め部が設けられていることが好ましい。
この発明によれば、テープを、爪と板状体のテープ用止め部とに跨って貼り付ける、あるいは、テープを、板状体のテープ用止め部の上から指に巻けば、板状体を爪に密着固定させることができるから、板状体の基端部分が爪の甲から浮くような現象を防ぐことができる。 In the ingrown nail correction tool of the present invention, it is preferable that a tape stopper for hooking a tape for fixing the plate-like body to the nail is provided on the base end side of the plate-like body.
According to this invention, the tape is pasted between the nail and the tape stopper of the plate-like body, or the tape is wound around the finger from above the tape stopper of the plate-like body. Can be tightly fixed to the nail, so that a phenomenon that the base end portion of the plate-like body floats from the back of the nail can be prevented.

本発明の陥入爪矯正具において、前記板状体は、前記挟持部の間隔方向において任意の形状に湾曲可能に構成されていることが好ましい。
この発明によれば、板状体を挟持部の間隔方向において任意の形状に湾曲させれば、陥入爪に対して矯正する力を変化させることができる。つまり、陥入爪の曲率よりも大きな曲率に湾曲させれば、矯正力が作用するから、痛みや矯正効果を考慮して、任意の形状に湾曲させることができる。 In the ingrown nail correction tool of the present invention, it is preferable that the plate-like body is configured to be able to be bent into an arbitrary shape in the interval direction of the clamping portion.
According to this invention, if the plate-like body is curved into an arbitrary shape in the interval direction of the sandwiching portion, the force for correcting the ingrown nail can be changed. That is, if the curvature is larger than the curvature of the ingrown nail, the correction force acts, so that it can be bent into an arbitrary shape in consideration of pain and the correction effect.

本発明の陥入爪矯正具において、前記陥入爪矯正具は、超弾性材料または形状記憶合金材料によって形成されていることが好ましい。
超弾性材料によって形成すれば、超弾性材料は、弾性限が広くプラトー領域を有することから、大きな変形が可能で、しかも、変形量に拘わらず略一定の矯正力を作用させることができる。従って、患者の痛みを持続的に軽減させることができる。
形状記憶合金材料によって形成すれば、例えば、体温より僅かに高い温度（例えば、４０℃以上の温度）のAf点（形状回復温度）を有する形状記憶合金材料によって形成すれば、陥入爪の中でも特に巻き爪の変形がひどく爪の矯正に痛みを伴うものに有効である。体温以下の温度では巻き爪の形状にフィットして変形し、矯正力もきわめて小さい。しかし、お湯やドライヤーなどで陥入爪矯正具を４０℃以上に温めると、記憶した形状に回復しようとして巻き爪を矯正するから、痛みの状態に応じて逐次矯正力を作用させることができる。 In the ingrown nail corrector of the present invention, the ingrown nail corrector is preferably made of a super elastic material or a shape memory alloy material.
If formed from a superelastic material, the superelastic material has a wide elastic limit and has a plateau region, so that it can be greatly deformed, and a substantially constant correction force can be applied regardless of the amount of deformation. Therefore, the patient's pain can be continuously reduced.
If it is made of a shape memory alloy material, for example, if it is made of a shape memory alloy material having an Af point (shape recovery temperature) that is slightly higher than the body temperature (for example, a temperature of 40 ° C. or higher), among the ingrown nails This is especially effective when the nail deformation is severe and painful in correcting the nail. At temperatures below body temperature, it fits and deforms to the shape of the wound nail and has very little correction power. However, when the ingrown nail correction tool is heated to 40 ° C. or higher with hot water or a dryer, the wound nail is corrected so as to recover the memorized shape, so that the correction force can be applied sequentially according to the state of pain.

FIG. 7 is a perspective view of a state where the ingrown nail correction tool is curved.

本実施形態の陥入爪矯正具１０は、図１〜図４に示すように、板状に形成された板状体１１と、この板状体１１の先端縁に間隔を隔てて設けられ陥入爪１の先端縁に差し込まれ陥入爪１を挟持する少なくとも２以上の挟持部１６とを備え、全体が弾性を有する材料（本実施形態ではばね用ステンレス板）によって一体的に形成されている。 As shown in FIGS. 1 to 4, the ingrown nail correction tool 10 of the present embodiment is provided with a plate-like body 11 formed in a plate shape and a tip edge of the plate-like body 11 with a gap therebetween. And at least two sandwiching portions 16 that are inserted into the leading edge of the nail 1 and sandwich the ingrown nail 1 and are integrally formed of an elastic material (a stainless steel plate for a spring in this embodiment) as a whole. Yes.

板状体１１は、幅寸法（爪幅方向寸法）が爪１の幅より僅かに小さく、長さ寸法（爪長さ方向寸法）が爪１の長さの約１／３〜１／５程度の矩形平板状に形成されている。また、板状体１１の基端側には、板状体１１を陥入爪１に固定するためのテープ１４（図６参照）が掛けられるテープ用止め部１２が設けられているとともに、両端側には板状体１１を陥入爪１に接着固定するための接着剤塗布用孔１３がそれぞれ設けられている。 The plate-like body 11 has a width dimension (claw width direction dimension) slightly smaller than the width of the claw 1 and a length dimension (claw length direction dimension) of about 1/3 to 1/5 of the length of the claw 1. It is formed in the shape of a rectangular flat plate. Further, on the base end side of the plate-like body 11, there are provided tape stoppers 12 on which a tape 14 (see FIG. 6) for fixing the plate-like body 11 to the ingrown claw 1 is hung. Adhesive application holes 13 for adhering and fixing the plate-like body 11 to the ingrown nail 1 are provided on the sides.

挟持部１６は、板状体１１の両端部先端縁から前方へ向かって一体的に延長された上挟持片１７と、この上挟持片１７の先端から裏面側に屈曲され上挟持片１７との間に差込隙間Ｓを有する下挟持片１８とを含んで構成されている。
下挟持片１８の長さＬは、２ｍｍ程度に形成されている。下挟持片１８の先端部は、先端縁に向かうに従って、上挟持片１７に対して次第に離れる方向へ傾斜されている。これにより、陥入爪１の先端に差し込みやすくなっている。上挟持片１７と下挟持片１８との差込隙間Ｓは、陥入爪１の厚みより小さい寸法、具体的には、０．１〜１．０ｍｍ、好ましくは、０．３〜０．５ｍｍ程度に形成されている。 The sandwiching portion 16 includes an upper sandwiching piece 17 that is integrally extended forward from the front end edges of both end portions of the plate-like body 11, and is bent from the distal end of the upper sandwiching piece 17 to the back surface side. And a lower clamping piece 18 having an insertion gap S therebetween.
The length L of the lower clamping piece 18 is formed to be about 2 mm. The distal end portion of the lower sandwiching piece 18 is inclined in a direction gradually separating from the upper sandwiching piece 17 toward the distal end edge. Thereby, it becomes easy to insert in the front-end | tip of the ingrown nail | claw 1. The insertion gap S between the upper clamping piece 17 and the lower clamping piece 18 is smaller than the thickness of the ingrown claw 1, specifically 0.1 to 1.0 mm, preferably 0.3 to 0.5 mm. It is formed to the extent.

このような構成の陥入爪矯正具１０を使用して陥入爪１を矯正するには、まず、陥入爪１の先端を指の先端より少なくとも２ｍｍ前後伸ばしてスクウェアカットすることが望ましい。陥入爪１の先端が適度に伸びた段階で、陥入爪矯正具１０を陥入爪１に取り付ける。つまり、板状体１１に設けられた２つの挟持部１６を、陥入爪１の先端縁に差し込む。すると、これらの挟持部１６の上挟持片１７と下挟持片１８とが陥入爪１の先端を挟持した状態となるので、陥入爪矯正具１０が陥入爪１に取り付けられる。従って、陥入爪１への取り付けが簡単に行え、しかも、取り外しも、陥入爪１から挟持部１６を引き抜くだけでよいから、取り外しも簡単にできる。
また、幅寸法の異なる陥入爪矯正具１０を複数用意しておけば、爪の先端が伸びるに従って順次大きい陥入爪矯正具１０に交換して、矯正力を強くしていくことができる。 In order to correct the ingrown nail 1 using the ingrown nail correction tool 10 having such a configuration, it is desirable to first cut the square by extending the tip of the ingrown nail 1 at least about 2 mm from the tip of the finger. The ingrown nail corrector 10 is attached to the ingrown nail 1 at the stage where the tip of the ingrown nail 1 is appropriately extended. That is, the two clamping portions 16 provided on the plate-like body 11 are inserted into the leading edge of the ingrown nail 1. Then, since the upper clamping piece 17 and the lower clamping piece 18 of these clamping parts 16 are in the state of clamping the tip of the ingrown nail 1, the ingrown nail corrector 10 is attached to the ingrown nail 1. Therefore, the attachment to the ingrown nail 1 can be easily performed, and the removal can be performed easily by simply pulling out the clamping portion 16 from the ingrown nail 1.
In addition, if a plurality of ingrown nail correction tools 10 having different width dimensions are prepared, the ingrown nail correction tool 10 can be replaced with a larger one as the tip of the nail extends, and the correction force can be increased.

陥入爪矯正具１０が陥入爪１に取り付けられた状態では、板状体１１および２つの挟持部１６の弾性によって、陥入爪１の先端縁両側が上方へ引き上げられる方向、つまり、陥入爪１の両側縁が平らに矯正される方向へ力が加えられるため、陥入爪１の矯正を陥入爪矯正具１０の弾性を利用した適切な力で持続的に行うことができる。
しかも、この状態においては、２つの挟持部１６が陥入爪１の先端縁を挟持し、板状体１１が陥入爪１の甲に沿って取り付けられた状態であるから、衣類（靴下）などに引っ掛かる虞も少ない。 In a state where the ingrown nail corrector 10 is attached to the ingrown nail 1, the both sides of the leading edge of the ingrown nail 1 are pulled upward by the elasticity of the plate-like body 11 and the two holding portions 16, that is, Since a force is applied in a direction in which both side edges of the nail 1 are corrected flat, the ingrown nail 1 can be corrected continuously with an appropriate force using the elasticity of the ingrown nail correction tool 10.
Moreover, in this state, since the two clamping portions 16 sandwich the leading edge of the ingrown nail 1 and the plate-like body 11 is attached along the back of the ingrown nail 1, clothing (socks) There is little possibility of getting caught in the area.

また、陥入爪１の形状や巻き込み度合いによっては、板状体１１の基端部分が陥入爪１の甲から浮いた状態になる場合が考えられる。
このような場合、図５に示すように、板状体１１の両端側には接着剤塗布用孔１３がそれぞれ設けられているから、この接着剤塗布用孔１３に接着剤１５を塗布し、爪の左右に板状体１１を動かすことにより、接着剤１５が爪と板状体１１との間に毛細管現象により入り込むため、接着を容易にできる。従って、板状体１１を陥入爪１に容易に接着固定できるとともに、板状体１１の基端部分が陥入爪１の甲から浮くのを防ぐことができる。
あるいは、図６に示すように、テープ１４を、陥入爪１と板状体１１の基端側のテープ用止め部１２とに跨って貼り付ける、あるいは、テープ１４を、板状体１１のテープ用止め部１２の上から指に巻けば、板状体１１を陥入爪１に密着固定することができるから、板状体１１の基端部分が陥入爪１の甲から浮くのを防ぐことができる。 Further, depending on the shape of the ingrown nail 1 and the degree of entrainment, the base end portion of the plate-like body 11 may be in a state of floating from the back of the ingrown nail 1.
In such a case, as shown in FIG. 5, since the adhesive application holes 13 are respectively provided at both ends of the plate-like body 11, the adhesive 15 is applied to the adhesive application holes 13, By moving the plate-like body 11 to the left and right of the nail, the adhesive 15 enters between the nail and the plate-like body 11 by a capillary phenomenon, so that the bonding can be facilitated. Therefore, the plate-like body 11 can be easily bonded and fixed to the ingrown nail 1 and the base end portion of the plate-like body 11 can be prevented from floating from the back of the ingrown nail 1.
Alternatively, as shown in FIG. 6, the tape 14 is pasted across the ingrown claw 1 and the tape stopper 12 on the proximal end side of the plate-like body 11, or the tape 14 is attached to the plate-like body 11. Since the plate-like body 11 can be tightly fixed to the ingrown nail 1 by winding it around the finger from above the tape stopper 12, the base end portion of the plate-like body 11 can be lifted from the back of the ingrown nail 1. Can be prevented.

このようにして、陥入爪１が矯正されていくと、陥入爪１は次第に正常な形状の爪、つまり、平らに矯正される。このようになると、陥入爪１の先端縁に作用する板状体１１の弾性力も次第に弱くなる。
このような場合でも、板状体１１を幅方向（挟持部が設けられた間隔方向）において任意に形状に湾曲させれば、陥入爪１に対して矯正する力を変化させることができる。つまり、陥入爪１の曲率よりも大きな曲率に湾曲させれば、より大きな矯正力が作用するから、痛みや矯正効果を考慮して、適切な形状に湾曲させることができる。 When the ingrown nail 1 is corrected in this way, the ingrown nail 1 is gradually corrected to a normal shape nail, that is, flat. If it becomes like this, the elastic force of the plate-shaped object 11 which acts on the front-end | tip edge of the ingrown nail | claw 1 will also become weak gradually.
Even in such a case, if the plate-like body 11 is arbitrarily bent in the width direction (interval direction in which the clamping portion is provided), the force for correcting the ingrown nail 1 can be changed. That is, if the curvature is larger than the curvature of the ingrown nail 1, a greater correction force is applied, so that it can be curved into an appropriate shape in consideration of pain and correction effect.

上述した形状の陥入爪矯正具１０では、板状体１１の先端縁から上挟持片１７を前方へ向かって一体的に延長し、この上挟持片１７の先端から下挟持片１８を裏面側に屈曲することによって、挟持部１６を構成できるため、つまり、１枚の板材を打ち抜き加工したのち、上挟持片１７および下挟持片１８を屈曲させるだけで構成することができるから、製造が簡単にできる利点がある。 In the ingrown nail correction tool 10 having the above-described shape, the upper holding piece 17 is integrally extended forward from the front end edge of the plate-like body 11, and the lower holding piece 18 is extended from the front end of the upper holding piece 17 to the back side. Since the sandwiching portion 16 can be configured by bending in a straight line, that is, it is possible to configure by simply bending the upper sandwiching piece 17 and the lower sandwiching piece 18 after punching a single plate material, and thus the manufacture is simple. There are advantages that can be made.

なお、第１実施形態では、板状体１１を平板状としたが、例えば、図７（Ａ）に示すように、陥入爪１の形状や巻き込み程度に応じて、幅方向（挟持部１６の間隔方向）に任意の形状に湾曲（あるいは屈曲）させて使用してもよい。
また、図７（Ｂ）に示すように、２つの挟持部１６を、板状体１１の先端縁から前方へ向かうに従って互いに離れる方向へ拡開されてもよい。このようにすれば、２つの挟持部１６が、板状体１１の先端縁から前方へ向かうに従って互いに離れる方向へ拡開されているから、爪１から外れにくい効果がある。 In addition, in 1st Embodiment, although the plate-shaped object 11 was made into flat plate shape, as shown to FIG. 7 (A), for example, according to the shape of the ingrown nail | claw 1, and the extent of entrainment (the clamping part 16). May be used by being bent (or bent) in an arbitrary shape in the interval direction.
Further, as shown in FIG. 7B, the two sandwiching portions 16 may be expanded in a direction away from each other toward the front from the tip edge of the plate-like body 11. In this way, since the two sandwiching portions 16 are expanded away from the tip edge of the plate-like body 11 in the forward direction, there is an effect that it is difficult to come off the claw 1.

図８は、本発明の第２実施形態の陥入爪矯正具を示す断面図、図９は図８のIX−IX線断面図である。これらの図の説明にあたって、第１実施形態と同一構成要素については、同一符号を付し、その説明を省略する。
第２実施形態の陥入爪矯正具２０は、陥入爪の先端部分形状に近似した矩形平板状の板状体２１と、この板状体２１の先端縁に切り起こし形成され板状体２１の裏面との間に差込隙間Ｓを有する挟持部としての切起片２６とを含んで構成されている。 <Second Embodiment>
FIG. 8 is a cross-sectional view showing an ingrown nail corrector according to a second embodiment of the present invention, and FIG. 9 is a cross-sectional view taken along the line IX-IX in FIG. In the description of these drawings, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted.
The ingrown nail correction tool 20 of the second embodiment is a plate 21 having a rectangular flat plate shape approximating the shape of the tip portion of the ingrown nail, and a plate-like body 21 formed by cutting and raising the tip end of the plate-like body 21. And a cut-and-raised piece 26 as a sandwiching portion having an insertion gap S between the rear surface and the rear surface.

板状体２１は、先端縁が陥入爪の先端形状に近似した円弧形状で全体が矩形平板状に形成されている。なお、この板状体２１にも、図示していないが、第１実施形態で述べたテープ用止め部１２や接着剤塗布用孔１３を設けてもよい。
切起片２６は、板状体２１の先端縁に、コ字状の切り込み２７を形成し、この切り込み２７に囲まれた内側部分２８を板状体２１の裏面側へ屈曲させることにより形成されている。切起片２６の長さＬ、および、切起片２６と板状体２１の裏面との間の差込隙間Ｓについては、第１実施形態を略同じである。 The plate-like body 21 has a circular arc shape whose tip edge approximates the tip shape of the ingrown nail, and is formed in a rectangular flat plate shape as a whole. Although not shown, the plate-like body 21 may be provided with the tape stopper 12 and the adhesive application hole 13 described in the first embodiment.
The cut and raised piece 26 is formed by forming a U-shaped cut 27 at the leading edge of the plate-like body 21 and bending the inner portion 28 surrounded by the cut 27 to the back side of the plate-like body 21. ing. The length L of the cut and raised piece 26 and the insertion gap S between the cut and raised piece 26 and the back surface of the plate-like body 21 are substantially the same as in the first embodiment.

第２実施形態の陥入爪矯正具２０によれば、切起片２６を陥入爪の先端縁に差し込むことにより、第１実施形態と同様に使用できる。
とくに、１枚の板材を、板状体２１の輪郭形状に打ち抜き加工すると同時に、その先端縁にコ字状に切り込み２７を入れ、その内側部分２８を切り起こすだけで構成できるから、製造が極めて簡単にできる。しかも、この構成では、挟持部である切起片２６が板状体２１の輪郭部分より内側に形成されるため、衣類（靴下）などに切起片２６が引っ掛かる虞がより少ない。 According to the ingrown nail correction tool 20 of the second embodiment, it can be used in the same manner as in the first embodiment by inserting the cut and raised piece 26 into the leading edge of the ingrown nail.
In particular, since a single plate material can be punched into the contour shape of the plate-like body 21 and at the same time a cut 27 is formed in a U-shape at the leading edge and the inner portion 28 can be cut up, manufacturing is extremely easy. Easy to do. In addition, in this configuration, since the cut and raised pieces 26 that are the sandwiching portions are formed inside the contour portion of the plate-like body 21, there is less possibility that the cut and raised pieces 26 are caught on clothes (socks) or the like.

＜第３実施形態＞
図１０は、本発明の第３実施形態の装飾用付け爪を示す斜視図、図１１は図１０のXI−XI線断面図である。これらの図の説明にあたって、前記各実施形態と同一構成要素については、同一符号を付し、その説明を省略する。
第３実施形態の装飾用付け爪３０は、弾性を有する材料によって輪郭形状が陥入爪に近似した形状でかつ板状に形成された板状体３１と、この板状体３１に間隔を隔てて設けられ陥入爪の先端縁に差し込まれ陥入爪を挟持する少なくとも２以上の挟持部としての切起片２６とを含んで構成されている。 <Third Embodiment>
10 is a perspective view showing a decorative nail according to a third embodiment of the present invention, and FIG. 11 is a sectional view taken along line XI-XI in FIG. In the description of these drawings, the same components as those in the above-described embodiments are denoted by the same reference numerals, and the description thereof is omitted.
The decorative nail 30 according to the third embodiment has a plate-like body 31 which is formed in a plate shape with a contour shape similar to an ingrown nail made of an elastic material, and is spaced from the plate-like body 31. And at least two cut and raised pieces 26 that are inserted into the tip edge of the ingrown nail and sandwich the ingrown nail.

板状体３１は、第２実施形態の板状体２１に対して、輪郭形状が異なるのみである。なお、図示していないが、板状体３１の表面（外表面）には、色彩、あるいは、模様などが付されていてもよい。または、色彩や模様が付されたシートなどを、板状体３１の表面に積層接着してもよい。このようにすれば、より意匠的効果に優れるため、装飾用付け爪としての効果をより発揮できる。 The plate-like body 31 is only different in outline shape from the plate-like body 21 of the second embodiment. Although not shown, the surface (outer surface) of the plate-like body 31 may be provided with a color or a pattern. Alternatively, a sheet or the like with a color or pattern may be laminated and bonded to the surface of the plate-like body 31. By doing so, since the design effect is more excellent, the effect as a decorative nail can be exhibited more.

第３実施形態の装飾用付け爪３０によれば、上述した陥入爪矯正具１０，２０で述べた効果のほかに、装飾用付け爪３０として使うことができる。従来の付け爪の場合、接着剤を用いて爪に取り付ける必要があるため、取り付け取り外しに手間がかかるが、本発明の装飾用付け爪では、これらの問題も解消できる利点がある。 According to the decorative nail 30 of the third embodiment, in addition to the effects described in the ingrown nail correction tools 10 and 20 described above, the decorative nail 30 can be used. In the case of a conventional artificial nail, since it is necessary to attach it to the nail using an adhesive, it takes time to attach and detach, but the decorative artificial nail of the present invention has an advantage that these problems can be solved.

＜変形例＞
本発明は前述の実施形態に限定されるものではなく、本発明の目的を達成できる範囲での変形、改良等は本発明に含まれる。
前記第１実施形態では、挟持部１６を上挟持片１７と下挟持片１８とで構成し、下挟持片１８の先端部を上挟持片１７に対して次第に離れる方向へ傾斜させて、差し込みを容易にしたが、これに限られない。
たとえば、図１２および図１３に示すように、下挟持片１８の先端を内側へ巻き込んで、つまり、上挟持片１７の裏面側に巻き込んで、円弧状に構成してもよい。このようにしても、下挟持片１８の円弧形状が陥入爪１の差し込みガイドとなるので、陥入爪１への差し込みを容易に行える利点がある。なお、第２、第３実施形態の切起片２６についても、図１２，図１３の構成を適用できる。 <Modification>
The present invention is not limited to the above-described embodiment, and modifications, improvements, and the like within the scope that can achieve the object of the present invention are included in the present invention.
In the first embodiment, the sandwiching portion 16 is composed of the upper sandwiching piece 17 and the lower sandwiching piece 18, and the tip of the lower sandwiching piece 18 is inclined away from the upper sandwiching piece 17 so as to be inserted. Although easy, it is not limited to this.
For example, as shown in FIGS. 12 and 13, the tip of the lower clamping piece 18 may be wound inward, that is, wound on the back surface side of the upper clamping piece 17, and may be configured in an arc shape. Even if it does in this way, since the circular arc shape of the lower clamping piece 18 becomes an insertion guide of the ingrown claw 1, there exists an advantage which can be easily inserted in the ingrown claw 1. The configurations shown in FIGS. 12 and 13 can be applied to the cut and raised pieces 26 of the second and third embodiments.

前記第１実施形態では、板状体１１の基端部に板状体１１を陥入爪１に固定するためのテープ１４が掛けられるテープ用止め部１２を設けたが、これに限られない。
たとえば、図１３に示すように、板状体１１の基端部に複数本（ここでは、２本）の脚片１２Ａを爪１の長さ方向に沿って一体的に延長し、これらをテープ用止め部１２とすれば、より確実に陥入爪矯正具１０，２０を陥入爪１に密着固定できる。 In the first embodiment, the tape stopper 12 on which the tape 14 for fixing the plate 11 to the ingrown claw 1 is provided at the base end of the plate 11 is not limited to this. .
For example, as shown in FIG. 13, a plurality of (here, two) leg pieces 12 </ b> A are integrally extended along the length direction of the claw 1 at the base end portion of the plate-like body 11, and these are taped. If it is set as the use stop part 12, the ingrown nail correction tools 10 and 20 can be more firmly fixed to the ingrown nail 1 more reliably.

前記各実施形態では、ステンレスを用いて陥入爪矯正具を構成したが、これに限らず、弾性を有する材料であれば、他の材料であってもよい。たとえば、樹脂などでもよく、あるいは、Ｔｉ−Ｎｉ系、鉄系、Ｃｕ系などの超弾性材料、形状記憶合金材料などでもよい。
超弾性材料によって形成すれば、超弾性材料は、弾性限が広くプラトー領域を有することから、大きな変形が可能で、しかも、変形量に拘わらず略一定の矯正力を作用させることができるから、患者の痛みを持続的に軽減させることができる。
形状記憶合金材料によって形成し、例えば、体温より僅かに高い温度（例えば、４０℃以上の温度）のAf点（形状回復温度）で、平な形状または正常な爪の形状に回復するように記憶させておけば、陥入爪の中でも特に巻き爪の変形がひどく爪の矯正に痛みを伴うものに有効である。体温以下の温度では巻き爪の形状にフィットして変形し、矯正力もきわめて小さい。しかし、お湯やドライヤーなどで陥入爪矯正具を４０℃以上に温めると、記憶した形状に回復しようとして巻き爪を矯正するから、痛みの状態に応じて逐次矯正力を作用させることができる。
また、その時は材料の相変態により矯正力も大きくなる。たとえば、少し熱めの風呂に入ったりすると、爪が柔らかくなる一方、矯正具は形状が回復して矯正が働き、更に矯正力が大きくなるから、爪に負担を掛けることが少ない状態でより高い矯正効果が期待できる。 In each said embodiment, although the ingrown nail correction tool was comprised using stainless steel, not only this but another material may be used if it is a material which has elasticity. For example, it may be a resin or the like, or a super elastic material such as Ti—Ni, iron, or Cu, or a shape memory alloy material.
If formed from a super elastic material, the super elastic material has a wide elastic limit and has a plateau region, so that it can be deformed greatly, and a substantially constant correction force can be applied regardless of the amount of deformation. The patient's pain can be continuously reduced.
Formed by shape memory alloy material, for example, memorized to recover to flat shape or normal nail shape at Af point (shape recovery temperature) slightly higher than body temperature (for example, temperature of 40 ° C or higher) If this is done, it is particularly effective for ingrown nails, especially those whose wounds are severely deformed and painful in correcting the nails. At temperatures below body temperature, it fits and deforms to the shape of the wound nail and has very little correction power. However, when the ingrown nail correction tool is heated to 40 ° C. or higher with hot water or a dryer, the wound nail is corrected so as to recover the memorized shape, so that the correction force can be applied sequentially according to the state of pain.
At that time, the correction force also increases due to the phase transformation of the material. For example, if you take a slightly hot bath, the nail will soften, but the corrector will recover and the correction will work, and the corrective power will increase, so it will be higher with less burden on the nail A correction effect can be expected.

前記実施形態では、単一の陥入爪矯正具や、装飾用付け爪について説明したが、適用する爪の大きさに応じて異なるサイズの複数の陥入爪矯正具や装飾用付け爪を用意しておき、これらの中から適用する（取り付ける）爪に応じて、選択的に使用するようにしてもよい。 In the above embodiment, a single ingrown nail corrector and a decorative nail have been described, but a plurality of ingrown nail correctors and decorative nail of different sizes are prepared according to the size of the nail to be applied. In addition, it may be used selectively according to the nail to be applied (attached) from these.
