Description

The present invention relates to a nail corrector for correcting and treating a curved shape of a deformed nail and a bent shape formed at a nail edge portion into a substantially flat shape.

In the invention of a correction tool for treating a conventional ingrown nail, a correction tool has been proposed that corrects a nail edge that has been bent and deformed into a nail cage into a substantially flat shape.

For example, a correction tool has been proposed in which a plate-shaped correction tool formed of an elastic material or a memory alloy is attached to the surface of a wound nail so that the curved and deformed nail edge is corrected to a substantially flat shape. (Patent Document 1)

Further, by forming a substantially U-shaped space by upper and lower locking pieces extending from the connecting portion, fitting both side edges of the claw into the U-shaped space, connecting the connecting portion with a connecting member, and pulling, There has also been proposed a corrector that corrects the ingrown nail with a lifting force against both side edges of the nail. (Patent Document 2)

Moreover, the correction which raises both sides of the tip edge of the ingrown nail upward by inserting it into the tip edge of the nail using two or more holding portions provided at intervals in a plate-like body formed of an elastic material. An orthodontic appliance that works and corrects both sides of the ingrown nail flat has also been proposed. (Patent Document 3)

The applicant of the present application first corrects the wound nail by attaching the correction tool formed in a substantially U-shaped cross section to the toe front flat part and then sliding sideways to the nail edge of the wound nail. A nail corrector characterized by a correction method by lateral sliding insertion has been proposed. (Patent Document 4)

In addition to the above-described curl nail corrector, the applicant of the present application inserts a toe of an ingrown nail generated in a person's nail into an accommodation gap provided in the ingrown nail corrector formed of a plastic material, and then into the gap. There has also been proposed an ingrown nail corrector that can correct the ingrown nail by pressing the ingrown nail correction tool into a substantially flat shape by plastic working together with the inserted ingrown nail. (Patent Document 5)

As a result of intensive studies on the onset of the ingrown nail, the inventor has until now established that the nail edge deformed into a curved shape is inserted into the nail cage or nail groove to cause the ingrown nail. However, the nail edge of the nail is bent downward (hereinafter referred to as “rib-shaped part”) to maintain the nail shape. Although there are various causes such as changes in the amount of moisturizing, the rib-shaped part suddenly deforms into a curved shape, which stimulates the soft tissue of the nailfold or nail groove and causes an ingrown nail with swelling and puncture. Turned out to be.

On the other hand, in the correction method of the ingrown nail correction tool described in the above-mentioned document 1, in order to correct the ingrown nail deformed into a curved shape, a flat elastic plate is bent so as to follow the curved deformation. For example, if it remains flat, it is difficult to apply it to the rib-shaped part deformed like a bowl, and the correction force to the rib-shaped part does not act. There's a problem.

Moreover, although the locking piece which has a substantially U-shaped space is provided in the correction tool both sides edge part of this ingrown nail correction tool which were hung up in the said literature 2, this locking piece latched by a nail edge part However, since it is a locking piece for hooking and locking, it is locked to the edge part of the nail edge, but there is a problem that the correction effect to the rib-shaped part cannot be obtained.

In the ingrown nail correction tool listed in the above-mentioned document 3, the clamping part is inserted from the tip edge of the nail, but the correction action on the edge part of the nail is not disclosed at the clamping part or the correction tool end. In addition, there is no disclosure of a structure that exerts a corrective action on the edge of the nail edge. Therefore, it does not have a correction ability with a means for laterally deforming the rib-like part. There is a problem that the soft tissue is not improved from the state where the rib-like portion is stuck.

Further, in the curly nail correction tool previously proposed in the above-mentioned literature 4 proposed by the present applicant, the side sliding buffer curved surfaces for smooth side sliding of the curl nail correction tool are provided at both ends of the lower leg. In this case, there is a problem that the rib-like portion is smoothly made by this buffering action, and there is no correction effect for hooking the rib-like portion to lie down or flatten.

The ingrown nail correction tool listed in Document 5 is also the correction tool previously proposed by the applicant,
While the ingrown nail is accommodated in the accommodation gap, the deformed nail is crushed and corrected to a flat shape by plastic deformation of the correction tool body by external pinching pressure. Since it does not have a correction ability with a means for deforming, when the rib-shaped portion is crushed, the rib-shaped portion deformed in a hook shape inwardly in the nail groove is in a state where a part of the nail-fold soft tissue is involved. There is a problem that leads to a dangerous situation that crushes in the direction and further exacerbates the stab wound.

Further, according to the study of the present inventor, when the curved deformation progresses also in the wound nail and the curved shape is further strongly deformed, the rib-like portion strengthens the acute angle of the curve and further pierces the nail-fold soft tissue. If the depth is deep and left unattended, the entire rib-shaped part is buried in the soft tissue and cannot be seen from the outside at all. It is not easy to mold it.

It should be noted that pulling out the rib-like portion buried in the nail-fold soft tissue or flat molding of the rib-like portion is an extremely important correction treatment in early improvement of nail-fold soft tissue puncture and swelling. Is not disclosed at all.

The object of the present invention is to solve these problems and to easily and safely correct the rib-like portion and the deformed nail embedded in the nail-fold soft tissue into a substantially flat shape, so that not only the nail-fold swelling but also the sting It is to provide a nail corrector that can easily improve infections and infections.

In order to solve the above-described problems, the first invention is that a cylinder formed in a cylindrical shape long in the nail width direction by an elastic material is provided with slits formed on both ends in the longitudinal direction of the cylinder. The slit has an upper holding portion and a lower holding portion that are inserted into the tip edge of the nail and sandwich the nail, and at least a part of the lower holding portion has a planar portion. And a molding side wall provided in a bending direction at an end portion in the sliding direction of the planar portion.

Here, the cross-sectional shape of the cylindrical body is not necessarily limited to the cylindrical shape, and may be an elliptical cylindrical shape or a polygonal cylindrical shape. In addition, if the flat portion provided in the lower holding portion is formed into a substantially flat surface shape that can be formed into a substantially flat shape by sandwiching a curved rib-like portion inserted into the opposed end surface of the slit. The flatness and area of the planar portion may be appropriately changed according to symptoms.
Further, the side wall for molding formed in the bending direction from the end portion in the sliding direction of the planar portion has a rib-like portion caught on the side wall for molding when the nail corrector is slid sideways and laterally outward. As long as the height of the molding side wall in the bending direction is lower within a range that does not interfere with the above-described function, the side wall for molding does not interfere with sliding when the side edge of the nail is slid laterally. Therefore, it is preferable.
The cylinder may be formed by cutting such as boring using a column.
Furthermore, if the material which forms a cylinder is a material which has the elastic performance which can crush the deformed nail clamped from the upper and lower sides by the upper side holding part and the lower side holding part into a substantially flat shape, for example, stainless steel, titanium alloy, It may be a noble metal alloy or a steel-based elastic material, or may be selected from a resin material as long as it has the elastic performance, in addition to an elastic material such as a super elastic material and a shape memory characteristic material.

A mounting example having such a configuration will be described with reference to FIG.
(1) First, the slit 12 formed along the cylindrical body is widened, and is sandwiched between the substantially flat tip edges (FIG. 3A) of the nail to be corrected. As a result, the nail corrector 10A is sandwiched in a state where the upper holding portion 13 and the lower holding portion 14 constituting the slit 12 are sandwiched between the substantially distal end portions of the nail. It should be noted that the holding (hereinafter referred to as “clamping”) force of the nail corrector 10A formed of a material having an elastic property capable of crushing the deformed nail into a substantially flat shape may be held by the nail at the leading edge of the nail. Provides stable installation.
(2) The nail corrector 10A is moved by side sliding to the vicinity of the rib-like portion 4 at the edge of the nail (FIG. 3 (b)). As a result, the curved nail edge portion is crushed into a substantially flat shape, so that the rib-like portion 4 fitted into the nail cage 5 soft tissue is exposed.
(3) When the planar portion 15 formed on the lower holding portion 14 slides the nail corrector 10A to an appropriate position (FIG. 3 (c)) sandwiching the rib-like portion 4, the rib-like shape is obtained. The part 4 is crushed and corrected by the clamping force. During the sliding, the rib-shaped portion 4 is deformed or scraped outwardly by the molding side wall 16 so as to be easily crushed. In addition, the curved deformed claw of the claw edge 3 is also crushed and corrected by the clamping force of the upper and lower holding parts (13, 14) provided in the slit.
(4) After the deformed nail is corrected to a substantially flat shape, the nail corrector 10A is detached by lateral sliding. (FIG. 3 (d)) Thus, in the orthodontic treatment of the rib-like portion 4 and the deformed nail, it is easy to handle and a safe therapeutic effect can be expected.
Here, the deformed claw means an ingrown nail or a wound nail.

In the nail corrector 10B according to the present invention, at least a part of the cylinder of the nail corrector is formed in a shape that is selected from a metal or a polymer compound to obtain plastic performance, or the nail corrector is formed by pinching. It is preferable that the material is selected and formed from materials having plastic performance that can achieve the above performance.

Thus, if a part or all of the cylindrical body is made of a material having plastic deformation so that the opening height w2 of the slit can be adjusted by plastic working, the deformation of the deformed nail having a large curved deformation can be corrected. In addition to being easy to handle, there is also an advantage that the clamping pressure for correction can be freely adjusted, and that the practitioner can perform correction with an appropriate clamping pressure in view of the state of cleavage of the nail.

An example of mounting will be described with reference to FIG.
(1) After the opening width w2 of the slit provided in the nail corrector 10B is appropriately adjusted to the deformed nail height, the nail tip edge in the vicinity of the rib-like portion is inserted into the gap of the slit. (Fig. 5 (a))
(2) Subsequently, the deformed nail 2 is corrected. The nail correction tool 10B is plastically deformed by adjusting the clamping pressure of the clamping tool (for example, pliers) until the deformed claw 2 is formed into a substantially flat shape in consideration of the toughness so as not to cleave. (Fig. 5 (b))
(3) After the plastic working, the nail corrector 10B is moved by side sliding until the end of the rib-like portion 4 comes to a position substantially in the center of the planar portion 15 (FIG. 5C). At the time of this lateral sliding, the rib-like portion is deformed laterally outwardly by the molding side wall 16. Further, the rib portion 4 and the deformed claw are inserted into the slit by sliding sideways.
(4) The rib-like portion 4 is held between the planar portion 15 and the upper holding portion 13, and the deformed claw is held between the upper holding portion 13 and the lower holding portion 14. From this state, plastic working is performed with an appropriate clamping pressure so as to increase the clamping force of the upper and lower clamping parts (13, 14) formed in the slit 12 using a clamping tool and the brittle nail material does not break. By doing so, the rib-like portion and the deformed claw are crushed and corrected to a substantially flat shape (FIG. 5D).
(5) After the nail deformation is corrected to a substantially flat shape, the nail corrector 10B can be safely and easily detached from the nail by side sliding as shown in FIG.

In this way, by adjusting the slit opening height of the nail corrector considering the nail quality and curved shape of each patient's deformed nail, it can be inserted into the gap of the slit regardless of the symptoms of the deformed nail. In addition, it can be treated with an appropriate correction force in consideration of the nail quality having deterioration etc. by adjusting the clamping force to the nail corrector, so that the rib-shaped part and the deformation can be safely performed without breaking the nail. The effect of correcting the nails to a flat shape can be expected. Before using the nail corrector 10B, the toe that has developed the deformed nail 2 is soaked in hot water of 38 ° C. to 43 ° C. for 20 minutes or more, and the deformed nail 2 is softened before being worn. Good.
