[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a correction device for correcting deformation of a nail, and in particular, to a flesh between a nail and a finger head, for example, so that one side edge and / or the other side edge of the nail rolls inward as the toenail extends. The present invention relates to a correction tool that corrects the deformation of a nail caused by a so-called ingrown nail.

[0002]

[Prior art]

 The conventional method of repairing ingrown nails, which is the background of the present invention, depends on the degree of ingrown nails, but for those with severe deformation of nails, a surgical operation is employed. In addition, a method of repairing an ingrown nail without selecting a surgical operation includes, for example, attaching a plate-shaped piece made of a shape memory alloy or a shape memory resin to the bent surface of the ingrown nail with an adhesive, A method has been proposed in which, by raising the temperature above a predetermined temperature, the ingrown nail is repaired by the restoring force of the plate-like piece.

[0003]

[Problems to be solved by the invention]

 However, with the surgical method, nails that have cut into the meat are partially cut and removed, making it difficult to operate when there is a risk of bacterial infection. Even if the ingrown nail is temporarily corrected by partially removing the nail by surgical operation, the ingrown nail in the winding direction may not be corrected, and the ingrown nail phenomenon may recur after surgery. Maybe. In addition, according to the method of using the restoring force of a plate-shaped piece made of a shape memory alloy or a shape memory resin as a method of not selecting a surgical operation, when the restoring force is out of a range due to elastic deformation of the shape memory material Not very effective. In addition, in this method, the plate-like piece is attached to the nail surface with an adhesive, so that if the adhesive strength of the adhesive is low, the plate-like piece is easily peeled off from the nail face, and conversely, the adhesive strength is too high In such a case, inconveniences such as impairing the restoring force of the plate-like piece may occur.

Therefore, a main object of the present invention is to correct the deformation of nails such as ingrown nails by a simple method without performing a surgical operation and to support natural growth of nails. The purpose is to provide a correction tool for correcting nail deformation.

[0005]

[Means for Solving the Problems]

 The correction tool for correcting deformation of a nail according to the present invention includes a first locking portion which is locked to one side edge in the width direction of the nail body, and a first engagement portion which is in contact with a part of the surface of the nail body. A first correction body having a contact portion and a first connecting hook connected to the first contact portion, and a second locking portion locked to the other side edge in the width direction of the claw body A second correction body having a second contact portion abutting a part of the surface of the claw body and a second connection hook portion connected to the second contact portion; and a first connection hook.

The correction operation section may be formed in an annular shape. Each of the first connection hook portion and the second connection hook portion may include, for example, one arranged in a state of standing substantially perpendicularly to the surface of the claw body. Each of the first locking portion and the second locking portion is a curved piece that bends, for example, from the side edge of the nail body toward the nail bed. The first straightening body and the second straightening body may be integrally formed of an elastic wire. The wire is preferably formed of a metal material such as spring steel. It is preferable that the nail correction device further includes a coating portion that covers the first connection hook portion, the second connection hook portion, and the correction operation portion. The covering portion is more effective when it includes a decoration effect portion to which a decoration technique is applied.

[0006] The first locking portion of the first straightening body and the second locking portion of the second straightening body are respectively locked to both ends in the width direction of the claw body. Both end edges in the width direction of the claw body are pulled up in the opposite direction (upward direction) to the winding direction of the ingrown claw by the correcting operation portion. Further, the first contact portion and the second contact portion are pressed downward on the claw surface at the center in the width direction of the claw body. Therefore, a pulling force in a direction opposite to the winding direction of the ingrown claw is continuously applied to both end edges in the width direction of the ingrown claw. Therefore, according to the correction device according to the present invention, it is possible to correct the deformation of nails such as ingrown nails and correct it. In the correction device according to the present invention, the first correction member, the second correction member, and the correction operation portion are each configured by separate and independent members, and are assembled by connecting these members. It is possible to appropriately and easily attach the correction tool according to the size and shape of the nail body. When the covering portion is formed so as to cover the first connecting hook portion, the second connecting hook portion, and the correcting operation portion, the connecting end between those members is protected, and the connecting force between the members is reduced. It becomes stronger and its coupling force is stably maintained. Furthermore, when the decorative part is formed by applying various decorative techniques to the covering part, the decorative part is excellent in aesthetic appearance. In particular, women and the like can easily perform orthodontic treatment with a kind of fashion sense. Become. In this correction tool, after the tension adjusting member is locked to the first locking portion and the second locking portion, the tension adjusting member is twisted across both ends of the tension adjusting member and wound around each other. By doing so, the winding portion is provided to extend between the first connecting hook portion and the second connecting hook portion. Then, an annular correcting operation portion is constructed between the first connection hook portion and the second connection hook portion. At this time, the longer the winding length of the winding portion is, the larger the pulling force acting on the first locking portion and the second locking portion can be. The shorter the length, the lower the pulling force.

The above and other objects, features and advantages of the present invention will become more apparent from the following detailed description of embodiments of the present invention with reference to the drawings.

[0008]

[Embodiment of the invention]

FIG. 1 is a perspective view showing an example of a base material of a correction tool for correcting deformation of a nail according to the present invention. The base material 10 used for constructing the correction device for correcting nail deformation according to the present embodiment includes a correction member base material 12 for forming a first correction member and a second correction member, and a correction member. And a base material 14 for a correction operation part for constituting an operation part.

[0009] The correction body base material 12 includes a base wire 16 having a length direction. For example, a substantially U-shaped convex portion 18 is formed at an intermediate portion in the length direction of the bus bar 16. The convex portion 18 protrudes in a direction orthogonal to the axial direction of the bus bar 16. An S-shaped bent portion 20 is formed between one end in the length direction of the bus bar 16 and the convex portion 18. The bent portion 20 is disposed on the same plane as the convex portion 18, and one end of the bent portion 20 extends in a direction opposite to the direction in which the convex portion 18 protrudes. Similarly, an S-shaped bent portion 22 is formed between the other end of the bus bar 16 in the length direction and the convex portion 18.

Further, another bent portion 24 having, for example, an inverted U shape is formed between one end in the length direction of the bus bar 16 and one bent portion 20. The bent portion 24 is connected to one end of the bent portion 20. The bent portion 24 is arranged on a plane orthogonal to the plane on which the convex portion 18 and the bent portion 20 are arranged. In this case, the bent portion 24 is provided to extend in a direction perpendicular to the axial direction of the base wire 16 as viewed in FIG. Similarly, an inverted U-shaped bent portion 26 is formed at one end of the bent portion 22 between the other end in the length direction of the bus bar 16 and the other bent portion 22.

The base wire 16, the convex portions 18, the bent portions 20, 22, and the bent portions 24, 26 constituting the orthodontic body base material 12 are integrally formed of an elastic metal material such as spring steel. In addition, the base material 12 for a correction body is not limited to spring steel or the like, and may be formed of an elastic material such as a synthetic resin material.

The correction operating portion base material 14 includes a tensile force adjusting member 28 made of, for example, a U-shaped wire. The tensile force adjusting member 28 has, for example, an arc-shaped curved portion 30 at the center in the longitudinal direction. Straight legs 28a and 28b are formed between one end of the tensile force adjusting member 28 and the curved portion 30 and between the other end of the tensile force adjusting member 28 and the curved portion 30, respectively. Further, ring-shaped insertion rings 36 and 38 are formed at one end and the other end of the tensile force adjusting member 28 via torsion portions 32 and 34, respectively. The tensile force adjusting member 28, the torsion portions 32 and 34, and the insertion rings 36 and 38 are integrally formed of an elastic metal material such as spring steel, similarly to the above-described base material 12 for a correction body. .

Next, a series of steps of a correction method in which the correction tool 100 is constructed using the above-described base material 10 and the deformation of nails such as ingrown nails is corrected using the correction tool 100 will be described. First, the base material 10 is prepared. Then, the first abutment is performed so that the correction material base material 12 of the base material 10 is arranged at a predetermined position on the nail surface of the ingrown nail to be corrected, for example, the nail body A of the toe. The bent portion 26 serving as a portion is applied in a plane, and the length of the first correction body 40 is registered. In this case, the portion serving as the first correction body 40 is appropriately adjusted according to the degree of curvature of the nail surface of the nail body A. After turning the convex portion 18 of the base material 12 for a correction body toward the toe and then standing substantially vertically upward, the initial bent portions 20, 22, 24, 26 of the base wire 16 can be formed. Positioning is performed. That is, the convex portion 18 of the bus bar 16 has an arrangement direction indicating function for clarifying the arrangement of the left and right bent portions 20, 22, 24, 26.

Next, as shown in FIG. 2, one end of the base wire 16 in the longitudinal direction is bent toward the bent portion 22 on the same plane as the bent portion 22 by a suitable bending means B. Thereby, the curved piece 42 is formed. In this case, the portion of the curved piece 42 is cut as short as possible, and the end portion is slightly bent toward the inside of the claw body. The corner end of the end portion is cut into a round portion 42a by sandstone milling, sanding or the like. The curved piece 42 has a function as a first locking portion, and is curved, for example, in an arc shape from one side edge in the width direction of the nail body A toward the nail floor.

Then, the bus bar 16 is cut by an appropriate cutting means C by the length of the registered first straightening body 40 as shown in FIG. The base wire 16 is cut at a predetermined portion of the bent portion 22, that is, at a dashed-dotted line XX shown in FIGS. 1 and 2. The bent portion 22 that has been cut and left is formed as a first connection hook portion 44 as shown in FIGS. 3, 4, 5, 6, and the like. The first connecting hook portion 44 is arranged so as to stand substantially perpendicularly to the claw surface of the claw body A.

Further, the first correction body 40 is locked from one end of the claw body A in the width direction to the vicinity of the center. In this case, while the bent portion 26 is pressed against the surface of the claw body A, the round portion 42 a of the bent portion 42 is locked to one side edge of the claw body A. It is to be noted that the nail body A is preliminarily disinfected appropriately in its entirety.

The second straightening body 46 is formed by the same steps as those for forming the first straightening body 40 described above. That is, the second straightening body 46 has a curved piece 48 as a second locking portion formed at one end in the length direction, and a second connection formed at the other end in the length direction. It comprises a hook portion 50 and a bent portion 24 as a second contact portion formed at an intermediate portion in the length direction. Then, the second straightening body 46 is locked from the other end in the width direction of the claw body A to the vicinity of the central part by the same process as the above-described method of attaching the first straightening body 40. That is, while the bent portion 24 is pressed along the surface of the claw body A, the rounded portion 48 a of the bent portion 48 is locked to the other side edge of the claw body A.

The first straightening body 40 and the second straightening body 46 are, for example, shown in FIG. 5, FIG. 6, FIG. 8, and FIG. The length is set so that the formation width W of about 3 mm can be secured, for example, about 3 mm.

Next, the tension adjusting member 28 is hooked on the first connecting hook 44 of the first straightening body 40 and the second connecting hook 50 of the second straightening body. In this case, as shown in FIG. 6, both ends of the tensile force adjusting member 28 in the length direction are arranged toward the toe, and the bending portion 30 has a predetermined length L in a direction opposite to the toe. Are hooked on the first connecting hook 44 and the second connecting hook 50 so as to be arranged at the same position.

Further, one end and the other end of the tensile force adjusting member 28 are crossed and twisted. In this case, as shown in FIG. 7, first, the insertion rings 36 and 38 of the tension adjusting member 28 are overlapped. Next, the winding member 52 is inserted into the inserted insertion rings 36 and 38. The hoisting member 52 has a hook 52a, and the hook 52a is inserted into the insertion rings 36 and 38. Then, the periphery of the curved portion 30 of the tension adjusting member 28 is pressed against the nail surface together with the first connecting hook portion 44 and the second connecting hook portion 50 by the thumb and forefinger of one hand and the other hand. The winding member 52 is wound, for example, by rotating it clockwise.

Then, the one leg 28 a and the other leg 28 b of the tension adjusting member 28 are screwed together with the torsion portions 32 and 34, and the winding portion 54 wound around each other is formed. It is formed in the longitudinal direction. At this time, the winding portion 54 is wound up such that its axis is disposed straight at substantially the center between the first connecting hook portion 44 and the second connecting hook portion 50. Thereby, between the first connecting hook portion 44 of the first straightening body 40 and the second connecting hook portion 50 of the second straightening body 46, the curved portion 30 of the tensile force adjusting member 28 and its vicinity are provided. An annular correction operating portion 56 constituted by portions is provided.

In this winding operation, the first connecting hook portion 44, the second connecting hook portion 50, and the curved piece 42 (first portion) are adjusted by adjusting the length of the winding portion 54 in the axial direction, that is, the amount of winding. And the bending piece 48 (corresponding to the second locking portion) to pull up the one edge and the other edge in the width direction of the claw body A. Is appropriately adjusted. That is, the longer the winding length of the winding portion 54 is, the greater the pulling force that causes the both side edges of the claw body A in the width direction can be increased, and the shorter the winding length of the winding portion 54 can be, the more. Thus, the pulling force that causes the side edges of the nail A in the width direction can be reduced.

When the patient (the subject) feels a pull on the nail body A, the winding operation is stopped, and the winding member 52 is removed from the insertion rings 36 and 38. Then, as shown in FIG. 9, the winding portion 54 is cut by the cutting means C at a portion near the straightening operation portion 56.

Next, the first connecting hook portion 44, the second connecting hook portion 50, and the correcting operation portion 56 are covered with a covering portion 58 made of a synthetic resin material such as an ultraviolet curable resin material. The formation of the covering portion 58 protects the connection end portions between the members of the first connection hook portion 44, the second connection hook portion 50, and the correction operation portion 56 from the external environment, and also includes those members. The connection force between them increases, and it is firmly held and fixed in a stable state.

In this embodiment, first, a predetermined amount of an ultraviolet-curable resin material is appropriately applied to the correction operation portion 56 and its peripheral portion (the portion including the first connection hook portion 44 and the second connection hook portion 50). Is done. Further, the portion to which the ultraviolet curable resin material is applied is irradiated with ultraviolet rays for a predetermined time. When the corresponding portion is cured, a block-shaped covering body 58a is formed so as to cover the first connecting hook portion 44, the second connecting hook portion 50, and the correcting operation portion 56. Then, the covering body 58a is processed into, for example, a heart shape as shown in FIG. 11 by a suitable cutting means or grinding means, and the covering portion 58 is formed. Thus, by forming the covering portion 58 into, for example, a heart shape, the aesthetic appearance is also excellent.

The correction tool 100 for correcting nail deformation according to the present embodiment includes a first correction body 40, a second correction body 46, and a tension adjusting member 28 forming a correction operation section 56. In the correction method for correcting the deformation of the nail using the correction tool 100, in particular, for example, as shown in FIG. The rounded portion 42a of 42 and the rounded portion 48a of the other curved piece 48 are respectively locked. Both ends of the claw body A are raised by the correction operating portion 56 in a direction (upward) opposite to the winding direction of the claw body A. In addition, one bent portion 26 and the other bent portion 24 press the center portion of the claw surface of the claw body A in the width direction downward. Therefore, the pulling force in the opposite direction to the winding direction of the claw body A continuously acts on both end edges in the width direction of the claw body A. Therefore, according to the correction tool 100 and the correction method using the same according to the present embodiment, the deformation of the nail body A can be corrected and corrected.

Further, in the present embodiment, the first correction body 40, the second correction body 46, and the correction operation section 56 are each constituted by a separate and independent member, and these members can be freely connected. Therefore, it is possible to appropriately and easily correct the nail according to the size, shape, and degree of curvature (deformation) of the nail body A of each patient (the subject). Since the nail surface of the nail body A has individual differences, the first correction body 40 and the second correction body are adjusted according to the size, shape, and degree of curvature of the nail body A of each individual, that is, the degree of curvature. The mounting positions of the correction operation part 46 and the correction operation part 56 are appropriately adjusted.

In the above-described embodiment, the cross-sectional shape of the bus bar 16 is circular as shown in FIG. 13, but the cross-sectional shape of the bus bar 16 is formed in a track shape as shown in FIG. 14, for example. May be done. In this case, the bus bar 16 is composed of plane portions 17a and 17b and semicircular arc portions 17c and 17d whose cross sections are parallel to each other, and one of the flat portions 17b contacts the claw surface of the claw body A. It is attached so that it touches. The cross-sectional shape of the bus bar 16 may be square, as shown in FIG. 15, for example, and may be other suitable shapes, such as rectangular cross-section, triangular cross-section, polygonal cross-section, and elliptical cross-section. It can be changed to In particular, when a bus bar 16 having a cross-sectional shape having a flat portion is employed, the contact area is larger than that of a bus bar 16 having a circular cross section, so that the pressing force of the claw body A against the claw surface is reduced. Can be more enhanced.

Further, in the above-described embodiment, the first straightening body 40 and the second straightening body 46 are formed integrally with the bus bar 16, but the first straightening body 40 and the second straightening body 46 are formed. May be separately formed as separate members, as shown in FIG. 16, for example.

Further, in the above-described embodiment, the covering portion 58 is provided by directly applying the ultraviolet curable resin material to a predetermined portion. However, the present invention is not limited to this. For example, as shown in FIG. After molding into a desired shape using such a molding die 60, it may be adhered to a predetermined portion by an adhesive or other attaching means. In this case, the covering portion 64 formed into a predetermined shape may be configured as a sealing body temporarily attached to the sheet surface, as shown in FIG. 18, for example, and the surface is subjected to various patterns. Alternatively, the covering portions 66 and 68 having the decorative portions exhibiting various decorative effects may be formed by applying gold foil or the like.
