FIG. The top view which shows typically the other modification of the ingrown nail correction tool which concerns on Example 4. FIG. FIG. 9 is a plan view showing an ingrown nail correction tool according to Example 5 of the present invention, omitting a tightening member.

The ingrown nail correction tool according to the embodiment of the present invention is separate from the first brace that can be attached to one side in the width direction of the nail and the first brace and can be attached to the other side in the width direction. With the second brace and the first brace and the second brace attached to the nail, it can be wound around the two braces, and can be tightened so as to pull both sides in the width direction toward the center in the width direction. And a winding fastening member.

The first brace includes a first bent portion formed by bending a linear elastic material into a wave shape including at least two semicircular arc portions in the same plane or a curved surface, and the first bent portion. A first locking portion which is provided at one end of the portion and can be locked to one side in the width direction of the nail, and an end on the opposite side of the nail in the width direction with respect to the first locking portion in the first bent portion A first free end portion is provided.

Further, the second brace includes a second bent portion formed by bending a linear elastic material into a wave shape including at least two semicircular arc portions within the same plane or a curved surface, and the second bent portion. A second locking portion that is provided at one end of the two bent portions and can be locked to the other side portion in the width direction of the claw; and an end on the opposite side of the claw width direction with respect to the second locking portion in the second bent portion And a second free end part which is a part.

The plane or curved surface means a straight plane or a curved surface obtained by curving the straight plane. Specifically, when the wave traveling direction and the wave height direction perpendicular to the wave traveling direction are the longitudinal direction and the width direction of the bending part, respectively, the curved surface has a flat surface with respect to the longitudinal center portion. In this case, both ends in the longitudinal direction are curved in the same direction.

The linear elastic material constituting the first bent portion and the second bent portion is, for example, a nickel-titanium alloy (Nitinol), a copper-aluminum-manganese alloy, or a copper-aluminum-nickel alloy, which is a superelastic alloy, For example, it is made of polyphenylsulfone, which is a superelastic resin, and its superelastic effect keeps the force to restore horizontally from the curved state constant and gives a stable correction force to the wound nail. To do.

The first bent portion is bent into a waveform in the same plane or a curved surface, and can be bent as a whole in a plane orthogonal to the plane or curved surface including a straight line passing through the first locking portion and the first free end portion. In the free state, the curved surface is flatter than the curved surface along the outer surface of the nail plate, or is a flat surface, and when bent as described above, the nail plate can be contacted. The same applies to the second bent portion.

Further, the plan view shapes of the first bent portion and the second bent portion are such that a plurality of semicircular arc-shaped portions continuously form a waveform within the plane or the curved surface.

Here, the semicircular arc-shaped portion is constituted by a part of an arc-shaped portion or a long arc-shaped portion formed with a circumferential angle in a range of 190 degrees to 300 degrees. This is because when the circumferential angle is less than 190 degrees, the restoring force from the curved state of the first and second bent portions is weak, and when it exceeds 300 degrees, the arc-shaped portions are bent so that they do not overlap in the same plane. This is because it becomes difficult to manufacture.

The first locking portion is configured from the tip of a hook-shaped portion that is locked to the back side of one side in the width direction of the nail plate, or is substantially made of resin on the front side of the side portion. It can be bonded or hooked freely. The same applies to the second locking portion.

Further, the number of semicircular arc-shaped portions in the first and second bent portions may be at least two. This is because a portion where the tightening member is wound is necessary and, for example, the first and second bent portions can be greatly deformed along the nail plate as compared with the case where the first and second bent portions are linear. .

Specifically, when the number of semicircular arc-shaped portions is less than two, there is almost no difference from a linear member, it is inconvenient to wind a winding member, and it is bent along a winding nail having a small radius of curvature. It becomes difficult. In particular, when at least two semicircular arc-shaped portions are used, a twist similar to that of a torsion bar occurs between the two semicircular arc-shaped portions, which enables bending along the nail plate of the wound nail having a small curvature radius. Because it becomes.

As the tightening member, a thin string formed of cotton, silk or resin thread, rubber thread or similar material is used.

The ingrown nail correction device may use the first and second devices symmetrically, and the size and wire diameter may be selected according to the size and deformation of the right and left of the ingrown nail. Also good. Further, the first locking portion of the first device is formed as a hook-shaped portion, and the second locking portion of the second device is engaged with the outside of the other side portion, for example, by bonding, for example, by bonding. It is good also as a structure which stops.

The structure to be locked by the above-mentioned bonding means that the end of the linear elastic material is pasted together with the thermoplastic resin (outside the side portion of the nail), or the linear elastic material is bonded to the bonded thermoplastic resin. It is a structure which inserts an edge part and hooks it directly or indirectly.

As shown in FIGS. 1 to 3, the ingrown nail correction tool 10 according to the first embodiment of the present invention includes a first appliance 20 that can be attached to the nail from one side in the width direction, and the nail to the other side in the width direction. The second brace 30 that can be worn from the top, and the first brace 20 and the second brace 30 that are attached to the nail can be wound around the nail, and both sides of the nail in the width direction are directed toward the center in the width direction. And a tightening member 40 that can be wound so as to be pulled.

The first brace 20 is formed by bending a linear elastic material into a wave shape including at least two semicircular arc portions in the same plane SP ₁ or a curved surface obtained by slightly curving the plane SP _1. The first bent portion 22, the first locking portion 24 provided at one end of the first bent portion 22, which can be locked to one side portion in the width direction of the nail, and the first bent portion 22. A first free end portion 26, which is an end portion on the opposite side in the width direction of the claw with respect to the locking portion 24, is configured.

In addition, the second brace 30 bends the linear elastic material into a wave shape including at least two semicircular arc portions in the same plane SP ₂ or a curved surface obtained by slightly curving the plane SP _2. The second bent portion 32 formed at the one end, the second bent portion 32 provided at one end of the second bent portion 32, which can be locked to the other side portion in the width direction of the claw, and the second bent portion 32 A second free end portion 36 that is an end portion on the opposite side of the claw in the width direction with respect to the second locking portion 34 is provided.

Further, as shown in FIG. 1, the plan view shape of the first bent portion 22 has a waveform in which seven semicircular arc portions 28A to 28G are continuous in the plane or the curved surface. Similarly, the second bent portion 32 is also formed in a waveform in which seven semicircular arc portions 38A to 38G are continuous.

The first locking portion 24 is composed of a tip end of a hook-shaped portion formed by raising one end of the first bent portion 22 at a substantially right angle to a plane or curved surface on which the semicircular arc-shaped portions 28A to 28G are formed. As shown in FIG. 3, the first U-shaped portion 23 is locked from the first bent portion 22 to the first locking portion so as to be locked to the back side of one side portion 50 </ b> A in the width direction of the nail plate 50. Up to the portion 24, the U-shape is bent continuously from the front surface to the back surface of the one side portion 50A so as to connect them.

Similarly, the second locking portion 34 is formed from the tip of the hook-shaped portion formed by raising one end of the second bent portion 32 substantially perpendicular to the plane or curved surface on which the semicircular arc-shaped portions 38A to 38G are formed. The second U-shaped portion 33 is configured to lock the second U-shaped portion 33 from the second bent portion 32 to the second locking portion 34. It is bent in a U shape from the front surface to the back surface of one side portion 50A so as to be connected.

The 1st free end part 26 and the 2nd free end part 36 are the end parts on the opposite side to the 1st U-shaped part 23 and the 2nd U-shaped part 33 of the 1st bent part 22 and the 2nd bent part 32, respectively. A circular arc having a circumferential angle of 360 degrees and smaller than the first and second

U-shaped portions

23 and 33 is formed in the plane or the curved surface.

In the first embodiment, the ingrown nail correction tool 10 has a left-right symmetric shape as shown in FIG. 1 with respect to the first brace 20 and the second brace 30. What is necessary is just to select a wire diameter, and left-right asymmetry may be sufficient.

Next, referring to FIG. 3, the first brace 20 and the second brace 30 according to the first embodiment are attached to the nail plate 50, and these are tightened by the tightening member 40. A process of correcting the wound nail by pulling the side part 50A and the other side part 50B will be described.

First, as shown in FIG. 3, the first locking portion 24 and the second locking portion 34 of the first brace 20 and the second brace 30 are connected to one side 50 </ b> A in the width direction of the nail plate 50 and the other. The side part 50B is mounted so as to be locked from the back side. This state is indicated by a solid line in FIG.

At this time, the end portions of the first device 20 and the second device 30 opposite to the first locking portion 24 and the second locking portion 34 are respectively connected to the first free end portion 26 and the second free end portion 36. Therefore, the first locking portion 24 and the second locking portion 34 are not hindered when locked to the back side of the

side portions

50A and 50B, and locking is easy.

Next, when the winding member 40 made of, for example, a thread is wound around the first free end portion 26 and the semicircular arc-shaped portion 38E in the second bent portion 32 and the winding member 40 is pulled, the first brace 20 is pulled. The first bent portion 22 is elastically deformed along the nail plate 50 as shown by a two-dot chain line in FIG. Similarly, when the second brace 30 is wound around the second free end portion 36 and the semicircular arc-shaped portion 28E portion of the first bent portion 22 and the tightening member 40 is tightened, the tightening force As shown by a two-dot chain line in FIG. 3, the second brace 30 is curved along the nail plate 50 from above the already curved first brace 20, and the winding member 40 is further moved to the first and 2 The first brace 20 and the second brace 30 are integrally bent along the nail plate 50 by being wound around the two bent portions 22 and 32. At this time, the first brace 20 and the second brace 30 are attracted to each other by the tightening force, so that the first and second bent portions 22 and 32 open between the respective arc-shaped portions in the longitudinal direction. It is extended elastically.

Due to the elastic restoring force from the bending of the first brace 20 and the second brace 30, the first locking part 24 pulls one side part 50A of the nail plate 50 counterclockwise in FIG. The stop portion 34 is pulled clockwise to the other side portion 50B of the nail plate 50, and the nail plate 50 in the wound nail state receives a force in the correction direction.

In addition, when the winding nail is corrected in the opening direction, the first locking portion 24 and the second locking portion 34 are displaced from the

side portions

50A and 50B. It is absorbed by the elastic restoring force from the extension in the longitudinal direction with the brace 30, and the elastic restoring force from bending due to the shift does not decrease.

Since the first brace 20 and the second brace 30 are separate, they can be easily attached to the side of the nail plate 50 as shown by the solid line in FIG. Further, since the first bent portion 22 and the second bent portion 32 are made of a bent linear elastic material, particularly a super elastic material, they are greatly deformed by the winding member 40 so as to follow the nail plate 50. Even if it is made, the force applied to one and the

other side portions

50A and 50B of the nail plate 50 is almost unchanged, and the wound nail is corrected with a uniform force regardless of the passage of time since the nail plate 50 is attached. can do.

Next, the process of attaching the first device 20 and the second device 30 to the model claws as shown in the photographs of FIGS. 4 to 19 and winding and fixing them will be described in more detail.

FIG. 4 shows a state in which a thread ring for fixing the thread-like winding member 40 to one side of the brace is made.

As shown in FIG. 5, the thread loop is hung on the second free end portion 36 of the second brace 30 in the state shown in FIG. 3 to tie the loop, and as shown in FIG. Wrap around one semicircular arc-shaped portion of the brace 20, and further wrap it around the second free end portion 36, and then wrap around the other semicircular arc-shaped portion of the first brace 20, as shown in FIGS. As shown, the above wrapping is repeated. Here, if the number of windings is too large, it is difficult to tighten the windings.

As shown in FIG. 9, when the tightening member 40 is pulled in the above-described winding state, the second brace 30 and the second free end portion 36 approach the nail plate 50 with a small force according to the principle of the pulley. Can be bent and drawn.

Next, as shown in FIG. 10, the second brace 30 is pulled to the lower side of the first brace 20, and the winding member 40 is passed through the first free end portion 26 as shown in FIG. Then, wrap around one of the semicircular arc-shaped portions of the second appliance 30.

5 to 7, the winding member 40 is wound 2 to 3 times between the first free end portion 26 and the semicircular arc portion of the second bent portion 32 (see FIGS. 12 to 14). Next, the winding member 40 is pulled to fix the second appliance 30 to the back side of the first appliance 20 by strongly pulling the end of the winding member 40 as shown in FIG.

Next, as shown in FIG. 16, the winding member 40 is reciprocated several times from above the overlapped first and

second devices

20 and 30 to each semicircular arc-shaped portion. When wound, the first device 20 and the second device 30 are integrally fixed to the claw as shown in FIGS. FIG. 19 shows a state in which this fixed state is viewed from the back side of the model claw.
