発明が解決しようとする課題Problems to be solved by the invention

湾曲状に変形した陥入爪の場合、爪縁部の爪甲面は劈開化しているため、そこから爪の水分が蒸発し過乾燥を起こしていたり、また汗等を吸収し水分の過吸水による膨張を起こしていたり等で、いずれにしても脆性化が進んでいるのだが、従来の矯正具で治療した場合、施術者が該矯正具を装着してしまうと爪の変化に適時対応した矯正力の制御が行えないため、矯正中に劈開を起こしてしまったり、生爪をはいでしまったりという問題があった。In the case of an ingrown nail deformed into a curved shape, the nail platen surface of the nail edge is cleaved, so that moisture of the nail evaporates and overdrying occurs, or sweat is absorbed to absorb excessive water. In any case, the embrittlement has progressed due to the swelling caused by, but when treated with a conventional orthodontic appliance, the practitioner responded to changes in the nail in a timely manner when the orthodontic appliance was worn. Since the correction force could not be controlled, there were problems such as cleavage during correction and removal of raw nails.

また、矯正具の先端溝に陥入爪を挿入し軟部組織に食い込む湾曲方向と逆らうような矯正方向へ操作し爪形を修復するＪ字状の本体を持つ陥入爪矯正具による治療の場合、脆性化が進んでいる陥入爪であっても無理に引き起こす矯正法のため他の手段の選択は無いことから陥入爪の治療には不向きである。また、爪加熱プレス式の爪矯正器の場合、美容のために考案されたもので、施術方法は爪を高温でプレスし成形するのだが、陥入爪は指の軟部組織に埋没しているため、陥入爪部のみを効率よく安全にプレスするのは無理である。In the case of treatment with an ingrown nail corrector with a J-shaped body that repairs the nail shape by operating in the correction direction opposite to the bending direction of inserting the ingrown nail into the tip groove of the corrector and biting into the soft tissue Even if the ingrown nail is becoming brittle, there is no choice of other means because of the correction method that causes it to forcefully, so it is not suitable for the treatment of the ingrown nail. In addition, the nail heating press type nail corrector was devised for beauty, and the treatment method is to press and mold the nail at a high temperature, but the ingrown nail is buried in the soft tissue of the finger Therefore, it is impossible to efficiently and safely press only the ingrown nail portion.

このように従来の矯正治療は脆性化している陥入爪には不向きで、また弾性変形を利用した矯正具の場合、劈開を避けるため矯正力を調整しても、靴などの外力に圧せられ該矯正具は装着している陥入爪の矯正形状を維持できず、略湾曲状へ爪縁ともども変形してしまうことから、治療期間が長期化する問題もある。Thus, conventional orthodontic treatments are not suitable for brittle ingrown nails, and in the case of orthodontic appliances that use elastic deformation, even if the correction force is adjusted to avoid cleavage, it can be pressed against external forces such as shoes. However, the correction tool cannot maintain the correction shape of the invaginated nail and is deformed to a substantially curved shape with the nail edge, which causes a problem that the treatment period is prolonged.

本発明は、このような問題に鑑みなされたもので、爪厚の薄い爪や老化し脆性化の進んだ爪等に発症した陥入爪に対しても、施術者の制御下で陥入爪部に無理な負担を強いることなく矯正治療を行うことができる固定形状型の陥入爪矯正具の提供を課題とする。The present invention has been made in view of such problems, and ingrown nails under the control of the practitioner can be applied to ingrown nails having thin nail thickness or aging and becoming more brittle. It is an object of the present invention to provide a fixed-shaped ingrown nail correction tool that can perform orthodontic treatment without imposing an excessive burden on the body.

課題を解決するための手段Means for solving the problem

本発明は、前記課題を解決するために、以下の手段を採用した。すなわち、従来の矯正治療が困難であった爪厚の薄い陥入爪や脆性化が進んでいる陥入爪であっても、爪を形成す るケラチンタンパク質のポリペプチド側鎖結合の再架橋と併用しながら本発明の陥入爪矯正具を用いることで矯正治療が安全に施せることをその要旨とする。The present invention employs the following means in order to solve the above problems. In other words, even ingrown nail which conventional orthodontic treatment is progressing thin ingrown nails and embrittled of TsumeAtsu been difficult, and re-cross-linked polypeptide side chain binding of keratin proteins that form a claw The gist is that the orthodontic treatment can be safely performed by using the ingrown nail correction tool of the present invention in combination.
