Description

本発明は、足の親指に生じている巻き爪を矯正するための巻き爪矯正具に関するものである。 The present invention relates to an incurvated nail correction tool for correcting an ingrown nail generated on a toe.

巻き爪矯正具としては、従来から種々の形状、構造を有するものが開発され、例えば、特許文献１に記載されているように、弾性を有する細長い薄板の先端部を下方に折り返して巻き爪の先端部に引っ掛ける係止片部に形成してなり、この係止片部を爪の甲部上に粘着テープによって固定して巻き爪の先端部に係止させた状態に保持するように構成した矯正具が開発されている。 As a curly nail corrector, tools having various shapes and structures have been developed. For example, as described in Patent Document 1, the tip of an elastic thin thin plate is folded downward so that the curled nail It is formed on a locking piece that is hooked to the tip, and this locking piece is fixed on the back of the nail with an adhesive tape and held in a locked state on the tip of the wound nail. Correction tools have been developed.

この巻き爪矯正具によれば、弾性を有する細長い薄板の先端部を下方に折り返して巻き爪の先端部に引っ掛ける係止片部に形成してなるものであるから、使用に際して、この係止片部を巻き爪の先端部に引っ掛けることにより巻き爪に対する装着が容易に行える利点を有するが、係止片部を巻き爪の先端部に引っ掛けた状態にしてこの矯正具を粘着テープによって爪の甲部上に固定しても、係止片部に巻き爪を引き起こそうとする充分な矯正力を生じさせることが困難であり、また、この矯正部を巻き爪の先端を支点として積極的に巻き爪の上面に向かって弾性変形させ、その弾性力によって係止片部に巻き爪を引き起こそうとする矯正力を生じさせようとしても、支点が巻き爪の先端であるため、係止片部を巻き爪の先端から前方に向かって離脱させる方向に作用して巻き爪を矯正する方向には殆ど作用せず、効果的な矯正力を得ることができないといった問題点があった。 According to this ingrown nail correction tool, since the tip of the elastic thin thin plate is formed in the locking piece that is folded downward and hooked to the tip of the winding nail, this locking piece is used in use. The hook is hooked on the tip of the nail so that it can be easily attached to the tip of the nail. Even if it is fixed on the part, it is difficult to generate sufficient correction force to cause the claw on the locking piece, and the correction part is positively used with the tip of the claw as a fulcrum. Even if it is elastically deformed toward the upper surface of the winding nail and an attempt is made to generate a correcting force that causes the locking piece to cause the winding nail to occur, the fulcrum is the tip of the winding nail. From the tip of the nail to the front Hardly acts in the direction to correct pincer nail acts in a direction to disengage, there is a problem that it is impossible to obtain effective corrective force.

このため、本願発明者等は、特許文献２に記載しているように、前端中央部に巻き爪に引っ掛ける係止フックを形成している係止片と、この係止片の後端から斜め上方に向かって傾斜しているレバー片とからなり、前端の係止フックを巻き爪に引っ掛け、爪の甲部上に係止片とレバー片との連接部を当接させ、この連接部を支点としてレバー片を下方に押圧し、この状態にして粘着テープによりレバー片を爪の甲部上に固定することにより、テコの原理でもって係止フックを上方に付勢して巻き爪矯正力を効果的に発生させるように構成した弾性的に屈曲変形可能な硬質合成樹脂製の巻き爪矯正具を開発した。 For this reason, as described in Patent Document 2, the inventors of the present application obliquely form a locking piece that forms a locking hook that is hooked on the winding claw at the center of the front end, and a rear end of the locking piece. It consists of a lever piece that is inclined upward, and the hook at the front end is hooked on the winding claw, and the connecting part of the locking piece and the lever piece is brought into contact with the back of the claw, and this connecting part is By pressing the lever piece downward as a fulcrum and fixing the lever piece on the back of the nail with adhesive tape in this state, the hook hook is urged upward by the lever principle and the curl nail correction force We have developed a curly nail corrector made of a hard synthetic resin that can be bent and deformed elastically.

Since other shapes are the same as those of the correction tool main body 1, the same portions are denoted by the same reference numerals and detailed description thereof is omitted. Thus, the correction tool main bodies 1 and 1 ′ are formed in a symmetrical shape.

上記のように構成した矯正具本体１（1'）は、図１、図２に示すように、その長さ方向を長方形状の粘着テープ10の長さ方向に対して直交する方向に向けてレバー片４の上面を粘着テープ10の粘着層11の中央部に接着することにより固着していると共に、矯正具本体１（1'）における係止片２の前端部と係止フック３とを粘着テープ10の一側端から外方に突出させた状態にして剥離紙12、12を粘着層11に剥離可能に貼着することにより巻き爪矯正具Ａ（A') を構成している。 As shown in FIGS. 1 and 2, the orthodontic appliance main body 1 (1 ′) configured as described above has its length direction oriented in a direction orthogonal to the length direction of the rectangular adhesive tape 10. The upper surface of the lever piece 4 is fixed by adhering it to the central portion of the adhesive layer 11 of the adhesive tape 10, and the front end portion of the engaging piece 2 and the engaging hook 3 in the corrector main body 1 (1 '). The nail correction tool A (A ′) is configured by sticking the release papers 12 and 12 to the adhesive layer 11 in a state of projecting outward from one end of the adhesive tape 10.

次に、このように構成した巻き爪矯正具Ａを使用して巻き爪Ｂを矯正する使用態様を説明すると、巻き爪Ｂが爪の左側端縁部に生じている場合には、巻き爪矯正具Ａを爪の甲上に配設した際に、矯正具本体１の長さ方向に平行な端面に形成している一側端面3aが、巻き爪Ｂが生じている親指の左側端面に向くように形成している係止フック３を有する巻き爪矯正具Ａを使用し、この巻き爪矯正具Ａを図６に示すように、その係止フック３の先端部を巻き爪Ｂの先端に引っ掛けて係止させる。 Next, the usage mode of correcting the ingrown nail B using the ingrown nail correction tool A configured as described above will be described. When the ingrown nail B is generated at the left edge portion of the nail, the ingrown nail correction is performed. When the tool A is arranged on the back of the nail, the one side end surface 3a formed on the end surface parallel to the length direction of the correction tool body 1 faces the left end surface of the thumb where the wound nail B is generated. A curl nail corrector A having a hook 3 formed as described above is used, and as shown in FIG. Hook and lock.

この際、係止フック３は、矯正具本体１の長さ方向に平行に形成している一側端面3aを巻き爪Ｂが生じている親指の左側端面側に向けていると共に、他側端面3bを係止フック３の基端側から先端に向かって係止フック３が幅狭くなる方向に傾斜した傾斜端面に形成しているので、矯正具本体１を爪の甲部上にその長さ方向を爪の長さ方向に向けた状態にして配置しても、その係止フック３の先端部を巻き爪Ｂの先端に正確に向けることができると共に、係止フック３をその先端が２〜３mm幅の先細形状に形成しているので、巻き爪Ｂの下面に容易に且つ確実に挿入、介在させて確実に係止させることができる。さらに、矯正具本体１はその長さ方向を爪の長さ方向に平行となるように向けて爪の甲部上に配置させることができるので、この矯正具本体１の長さ方向にその長さ方向を直交させて矯正具本体１を固定させている粘着テープ10を、巻き爪Ｂが生じている親指の周方向に正確に指向させることができる。 At this time, the locking hook 3 has one side end face 3a formed in parallel with the length direction of the correction tool body 1 facing the left end face side of the thumb where the wound nail B is formed, and the other end face. 3b is formed on the inclined end face inclined in the direction in which the locking hook 3 becomes narrower from the proximal end side to the distal end side of the locking hook 3, so that the length of the correction tool main body 1 is on the upper part of the nail. Even if it is arranged with the direction oriented in the direction of the length of the claw, the tip of the locking hook 3 can be accurately directed to the tip of the wound claw B, and the tip of the locking hook 3 is 2 Since it is formed in a tapered shape having a width of ˜3 mm, it can be easily and reliably inserted and interposed in the lower surface of the wound claw B so as to be reliably locked. Further, since the orthodontic appliance main body 1 can be arranged on the upper part of the nail so that the length direction thereof is parallel to the length direction of the nail, the length of the orthodontic appliance main body 1 in the length direction is long. The pressure-sensitive adhesive tape 10 that fixes the orthodontic appliance main body 1 by making the direction perpendicular to each other can be accurately oriented in the circumferential direction of the thumb where the wound nail B is generated.

さらに、粘着テープ10の剥離紙12、12を剥離すると共に、巻き爪Ｂが生じている爪の甲部上に配置したレバー片４を支点部５を中心として弾性的に撓ませながら下方に押し下げて巻き爪Ｂの甲部上に押し付けることにより、テコ原理で係止フック３を上方に付勢して巻き爪矯正力を発生させ、この状態にして粘着テープ10を親指に巻着することによって矯正具本体１を固定し、支点部５を中心とするテコの作用による上記巻き爪矯正力をそのまま保持させる。 Further, the release papers 12 and 12 of the adhesive tape 10 are peeled off, and the lever piece 4 arranged on the back of the nail where the winding nail B is generated is pushed downward while being elastically bent around the fulcrum 5. By pressing the upper part of the ingrown nail B on the back of the nail B, the locking hook 3 is urged upward by the lever principle to generate the incurvated nail correction force, and in this state, the adhesive tape 10 is wound around the thumb. The correction tool main body 1 is fixed, and the above-mentioned curl nail correction force due to the lever action around the fulcrum portion 5 is held as it is.

また、上述したように、レバー片４の幅方向の中央を通る矯正具本体１の中心線Ｘに対して、係止フック３の基端屈曲部６の幅方向の中央を通る中心線X1が係止片２の一側端面2a側に所定幅だけ偏位させて係止フック３の先端を巻き爪Ｂの先端に係止させた時に、矯正具本体１の一側端部が爪の甲部から外側方に出来るだけはみ出さないように形成しているので、矯正具本体１を妄動させることなく粘着テープにより所定の位置に確実且つ安定した状態で固定することができる。 Further, as described above, the center line X1 passing through the center in the width direction of the proximal bent portion 6 of the locking hook 3 is relative to the center line X of the correction tool body 1 passing through the center in the width direction of the lever piece 4. When the front end of the locking hook 3 is locked to the front end of the wound claw B by being displaced by a predetermined width toward the one end surface 2a side of the locking piece 2, the one side end of the correction tool body 1 is the back of the nail. Since it is formed so as not to protrude as far as possible outward from the part, the correction tool main body 1 can be securely and stably fixed to a predetermined position by the adhesive tape without causing reluctance.

次に、巻き爪B'が爪の右側端縁部に生じている場合には、巻き爪矯正具A'を爪の甲上に配設した際に、矯正具本体1'の長さ方向に平行な端面に形成している他側端面3bが、巻き爪Ｂが生じている親指の右側端面に向くように形成した係止フック３を有する巻き爪矯正具A'を使用し、この巻き爪矯正具A'を図９に示すように、その係止フック３の先端部を巻き爪B'の先端に引っ掛けて係止させる。 Next, when the rolled nail B ′ is formed on the right edge of the nail, when the rolled nail correction tool A ′ is placed on the upper side of the nail, the length of the correction tool body 1 ′ is increased. Using the curl nail correction tool A ′ having the locking hook 3 formed so that the other side end surface 3b formed on the parallel end surface faces the right end surface of the thumb where the curl nail B is generated, As shown in FIG. 9, the correction tool A ′ is locked by hooking the tip of the locking hook 3 to the tip of the wound claw B ′.

この際、係止フック３は、矯正具本体1'の長さ方向に平行に形成している他側端面3bを巻き爪B'が生じている親指の右側端面側に向けていると共に、一側端面3aを係止フック３の基端側から先端に向かって係止フック３が幅狭くなる方向に傾斜した傾斜端面に形成しているので、矯正具本体1'を爪の甲部上にその長さ方向を爪の長さ方向に向けた状態にして配置しても、その係止フック３の先端部を巻き爪B'の先端に正確に向けることができると共に、係止フック３をその先端が２〜３mm幅の先細形状に形成しているので、巻き爪B'の下面に容易に且つ確実に挿入、介在させて確実に係止させることができる。さらに、矯正具本体1'はその長さ方向を爪の長さ方向に平行となるように向けて爪の甲部上に配置させることができるので、この矯正具本体1'の長さ方向にその長さ方向を直交させて矯正具本体1'を固定させている粘着テープ10を、巻き爪B'が生じている親指の周方向に正確に指向させることができる。 At this time, the locking hook 3 has the other side end surface 3b formed parallel to the length direction of the correction tool main body 1 'directed toward the right end surface side of the thumb where the wound claw B' is generated. Since the side end face 3a is formed as an inclined end face inclined in the direction in which the locking hook 3 becomes narrower from the proximal end side to the distal end of the locking hook 3, the correction tool body 1 'is placed on the upper part of the nail. Even if it is arranged with its length direction oriented in the direction of the length of the claw, the tip of the locking hook 3 can be accurately directed to the tip of the wound claw B ′, and the locking hook 3 can be Since the tip thereof is formed in a tapered shape having a width of 2 to 3 mm, it can be easily and surely inserted and interposed in the lower surface of the wound claw B ′ so as to be reliably locked. Furthermore, the orthodontic appliance main body 1 ′ can be arranged on the upper part of the nail so that its length direction is parallel to the length direction of the nail. The pressure-sensitive adhesive tape 10 that fixes the correction tool main body 1 ′ with its length direction orthogonal can be accurately oriented in the circumferential direction of the thumb where the wound nail B ′ is generated.

さらに、粘着テープ10の剥離紙12、12を剥離すると共に、巻き爪B'が生じている爪の甲部上に配置したレバー片４を支点部５を中心として弾性的に撓ませながら下方に押し下げて巻き爪B'の甲部上に押し付けることにより、テコ原理で係止フック３を上方に付勢して巻き爪矯正力を発生させ、この状態にして粘着テープ10を親指に巻着することによって矯正具本体1'を固定し、支点部５を中心とするテコの作用による上記巻き爪矯正力をそのまま保持させる。 Further, the release papers 12 and 12 of the adhesive tape 10 are peeled off, and the lever piece 4 arranged on the upper part of the nail where the wound claw B ′ is generated is bent downward while being elastically bent around the fulcrum part 5. By pushing down and pressing on the upper part of the wound nail B ′, the latch hook 3 is urged upward by the lever principle to generate the wound nail correction force, and in this state, the adhesive tape 10 is wound around the thumb. As a result, the correction tool main body 1 'is fixed, and the above-mentioned curl nail correction force due to the lever action around the fulcrum portion 5 is maintained as it is.

また、上述したように、レバー片４の幅方向の中央を通る矯正具本体1'の中心線Ｘに対して、係止フック３の基端屈曲部６の幅方向の中央を通る中心線X2が係止片２の他側端面2b側に所定幅だけ偏位させて係止フック３の先端を巻き爪B'の先端に係止させた時に、矯正具本体１の他側端部が爪の甲部から外側方に出来るだけはみ出さないように形成しているので、矯正具本体１を妄動させることなく粘着テープにより所定の位置に確実且つ安定した状態で固定することができる。 Further, as described above, the center line X2 passing through the center in the width direction of the proximal bent portion 6 of the locking hook 3 with respect to the center line X of the correction tool main body 1 'passing through the center in the width direction of the lever piece 4. Is shifted to the other end surface 2b side of the locking piece 2 by a predetermined width, and when the tip of the locking hook 3 is locked to the tip of the wound claw B ′, the other side end of the correction tool body 1 is nail. Since it is formed so as not to protrude as far as possible from the back of the upper part, the correction tool main body 1 can be securely and stably fixed to a predetermined position by the adhesive tape without causing reluctance.
