The inventor of the present invention has observed the progress of the improvement of the correction treatment of deformed nails, which progressed from mild to severe respectively, and found that the correction treatment of moderate or more deformed nails requires a long treatment period of 3 months or more. As a result of intensive studies on the reason why the moderately or more deformed nails require long-term treatment, most of the slightly deformed nails have a large gentle curved shape with a deformed nail edge, but a single bent. In the case of moderately or more deformed nails, (1) deformation of the nail plate causes bending deformation in the form of a curved nail . (2) The claw deformation from the vicinity of the claw edge to the claw edge is in a strong curved shape or a small arc shape, and is curled and deformed to involve the claw groove. I found that. That is, it has been found that two or more curved deformations different from the above (1) and (2) are combined to form one deformed claw.

The deformed nail correctors described in the above-mentioned Documents 1 to 3 aim at restoring by using any one of the correcting actions such as elastic stress (action) and pinching force (action). Not have the shape or structure of the orthosis that can cope with orthodontic treatment when two or more curved deformations seen in a deformed nail of a degree or more are complexly developed. There is also a problem that it is not adapted to the correction treatment of moderately or more deformed nails, since the reference to correct the sclerosis is not described in the disclosure of the above publication.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-described problem of the orthosis and to easily and safely correct a deformed nail in at least two or more complex curved shapes into a substantially flat shape. It is an object of the present invention to provide a nail corrector which can improve not only the early stage of swelling but also the swelling of the nail fold and the puncture of soft tissue at an early stage.

The invention of claim 1 for solving the above-mentioned problem is a deformed nail corrector for developing bilateral nail margins, which is made of an elastic material for correcting a deformed nail plate, and comprising a deformed nail. A nail plate correction tool that can be corrected and repaired to a substantially flat shape by being erected on the surface of the affected nail plate, and arranged on both sides of the nail to correct the deformed nail edge A rectangular slit formed in a substantially rectangular cylindrical shape that is long in the claw width direction and made of an elastic material, which is a pair of two, has a long slit formed at both longitudinal end portions of the rectangular cylindrical body. The opposed surface of the long slit includes a lower surface of an upper holding portion and an upper surface of a lower holding portion of the rectangular cylinder, and the opposite surface to the opening side of the long slit in the rectangular cylinder, It has a short slit formed from one longitudinal end to a substantially central portion of the rectangular cylinder, and the long slit has a tip of a deformed claw edge. Is inserted, and when viewed in the longitudinal direction of the rectangular cylinder, portions of the upper holding portion and the lower holding portion on the side opposite to the short slit side are corrected to have a deformed claw edge portion substantially flat by clamping force. An elastic plate capable of correcting the lower edge of the short slit side by bending the claw edge by elastic stress, and setting the upper edge of the short slit side to jump up the nail. The short slit side portion of the upper holding portion and the lower holding portion as an elasticity correcting action portion, and furthermore, an appropriate position on the side end surface of the rectangular cylindrical body, and in the longitudinal direction. And a nail edge correction tool provided with a fitting hole or an insertion groove into which the nail tool correction tool can be fitted.

The cross-sectional shape of the rectangular cylinder body of the above-described nail edge correction tool is not necessarily limited to a rectangular cylinder, but may be a cylindrical shape, an elliptical cylindrical shape, or a polygonal cylindrical shape. Further, the short cross-sectional shape of the elastic plate may be a semicircular shape, a linear shape, or a finely-crafted spring shape, and the fitting hole into which the nail plate correction tool is inserted is formed at an end of the nail plate correction portion. In order to prevent exposure, the claw section side end may be formed with a sealed hole.

The nail holding part attached to the nail rim correction device may have a length that is considered in consideration of the length of the elastic plate.Also, depending on the surroundings of the nail, such as when the swelling of the nail fold is severely swollen, In a case where the attachment of the pressing portion makes it difficult to mount the nail edge correction tool, the attachment may not be provided.

The method of mounting the nail rim correction tool is that when the nail rim is slightly curved, the short slit side end face is directed to the claw groove side, and it is mounted by sliding laterally from the nail plate side to the nail fold end If the edge of the nail is severely curved, the short slit side end face should face the nail plate side and should be attached from the nail edge end side. However, the practitioner may appropriately select and perform the mounting considering the nail quality without depending on the above-described means.

In the deformed nail corrector configured as described above, the invention according to claim 2 is directed to the nail width direction using an elastic material instead of the nail edge corrector attached to the undeformed nail edge of the one-sided wound nail. A rectangular cylinder shaped into a substantially rectangular cylinder , and the rectangular cylinder includes a slit formed over both longitudinal end portions of the rectangular cylinder, and a facing surface of the slit includes: There is an upper holding portion and a lower holding portion that can be inserted and pinched into the nail tip edge, and a fitting hole or a fitting hole into which the correction tool for nail plate can be fitted in an appropriate position at the end surface of the rectangular cylindrical body and in the longitudinal direction. It is characterized in that a claw tip edge locking tool provided with an insertion groove is provided .

When performing the correction treatment for the nail that has developed on only one side of the deformed nail, when using the above-mentioned deformed nail corrector for both ingrown nails, apply the corrective force to the normal nail margin and nail plate on one side. This can lead to accidents, such as stripping raw nails or breaking nails. Further, it can be assumed that the treatment period is further extended by such an accident. Therefore, the correction tool for the nail edge, which is attached to the normal nail edge attached to the deformed nail correction tool for both-sided ingrown nails, is replaced with the nail tip edge locking tool, and is engaged with the tip edge substantially at the center of the nail width. By being stopped, the safety of the normal nail margin can be ensured, and moreover, by designing the corrective ability in view of the degree of deformation of one nail edge, more effective and safe treatment can be performed. it can. In addition, the cross-sectional shape of the rectangular cylinder body of the claw tip edge locking device is not necessarily limited to the rectangular cylinder, and may be a cylindrical shape, an elliptical cylindrical shape, or a polygonal cylindrical shape.

In addition, not only for the correction of one-sided nails, but also for the two-sided nails, if there is a difference in nail deformation that occurred on the left and right nail margins, adjustment is performed with a corrective action suitable for the deformation that occurred on each nail edge And each may be used.

According to the third aspect of the present invention , instead of fitting the nail plate correction tool into the fitting hole of the nail plate correction tool, the nail plate correction tool and the nail plate correction tool are integrally formed. Good.

The materials used for the nail plate correction tool and nail edge correction tool provided in any of the deformed nail correction tools described above include, for example, ABS in resins, styrene copolymers, PE, PP, PS, and PVC. , FRP, ionomer, acrylic and PET can be appropriately selected and used. In addition, from elastic metals, for example, steel, alloy steel, carbon steel, stainless steel, copper alloy, titanium, titanium alloy, cobalt alloy, nickel-titanium alloy, nickel-titanium alloy, shape memory alloy, etc. are used as long as they have elasticity. it can.

Also, the fixing method of these deformed nail correction tools is not limited to pinching, and in consideration of long-term stable fixing, for example, using a fixing means using an adhesive, an adhesive, a gel, an adhesive tape, or the like. May be.

Here, the deformed nail means a nail that is curved and deformed, such as an ingrown nail or an ingrown nail.

According to the first aspect of the present invention, the nail plate correction tool includes a nail plate correction tool, and a nail margin correction tool including a pinching correction correction section and an elastic correction correction section. With this configuration, for a deformed nail formed by two or more different curved shapes, it is possible to individually design a corrective force suitable for each of the curved deformations. Thus, an effect can be obtained by treating the deformed nail.

According to the second aspect of the present invention, in the case of the deformed nail corrector according to the first aspect, since the nail edge corrector is locked to the nail edges on both sides, the correcting action acts on the both nail edges. On the other hand, when correcting a one-sided deformed nail that has developed on one of the nail margins, changing one of the nail-edge correction tools that does not have deformed nails to a nail tip edge locking tool, It became a deformed nail corrector for deformed nails. Thereby, the deformed nail corrector for one-side deformed nails not only eliminates the burden on the nail edge on the side where the deformed nail is not developed, but also develops without considering the shape of the nail edges on both sides. Since a corrective ability suitable for only one side of the deformed nail can be designed, a safer and more effective treatment can be performed. In addition, using this effect, if the nail deformation of each nail edge is different, design the corrective ability in consideration of the curved symptom separately for the left and right, and arrange this correction tool at each nail edge May be.

According to the third aspect of the present invention, the nail plate correction tool and the nail rim correction tool are each integrated with each other in a range that does not deviate from the effects of the present invention, in consideration of the efficiency of the manufacturing cost reduction and the hygiene management aspect. And may be molded.
