In the present invention, the nail plate-shaped curved deformed portion for the first correction purpose and the nail side edge bent shape deformed portion for the second correction purpose are vertically opposed to urge the pressurizing force of the pressurizing tool. The present invention relates to a multipurpose nail corrector that can be corrected and treated by a pressure flattening action using a nail corrector made of a pair of upper and lower flattening plates provided at the pressurizing work sites of an upper leg and a lower leg, respectively.

In the invention of a conventional correction tool for treating deformed nails, a correction tool that is attached to the tip edge of the nail and corrects the nail shape to a substantially flat shape has been proposed.

For example, the applicant of the present application first attaches a correction tool having a substantially U-shaped cross section to the flat portion of the nail tip edge, and then slides it to the curved deformation nail edge to correct the deformation nail. An ingrown nail correction tool characterized by a correction method using lateral sliding insertion has been proposed. (Patent Document 1)

Further, the applicant of the present application has inserted the nail tip edge, which is deformed into the accommodation gap provided in the correction tool formed of a plastic material, in addition to the wound nail correction tool, and then inserted the defect inserted into the gap. There has also been proposed an ingrown nail corrector which can correct the ingrown nail by pressing the ingrown nail correction tool into a substantially flat shape by plastic working and plastically deforming it. (Patent Document 2)

Further, in addition to the above-described nail correction tool, the applicant of the present application is formed on a cylindrical body that is long in the nail width direction by a material having elasticity, and is formed over both ends in the longitudinal direction of the cylindrical body. There is a slit, and an opposing end face of 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 is a planar portion And using a molding side wall provided in a vertical direction at the sliding direction end of the planar portion, by hooking the nail edge that is bent downward and fitted, scraped off, and crushed A nail corrector that can be corrected to a substantially flat shape has also been proposed. (Patent Document 3)

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 side edge is formed with a flange that is bent downward for the purpose of reinforcing the nail shape. Bending deformed flange-like part (hereinafter referred to as “bending deformed part”), which has been further sharpened inward by compression, stimulates the soft tissue of the nail cage or nail groove, resulting in ingrown nail with swelling and sting Turned out to be.

On the other hand, in the curled nail corrector proposed in the above-mentioned document 1 previously proposed by the present applicant, a lateral sliding buffer curved surface for smooth side sliding of the curled nail corrector is provided on the lower leg. The side nail correction tool mounted on the flat nail tip edge approximately in the middle of the nail width can be smoothly slid sideways by using the buffering action of the side sliding buffer curved surface. While moving to the edge of the nail, it is a means of correcting and treating the deformed nail to a flat shape, but at that time, the existence of a flexion deformed part was not known, so the curvature that developed in the nail plate There is only a purpose of correcting the deformed portion, and there is a problem that a function or means for correcting the bent deformation portion of the nail edge portion portion to a flat shape is not provided.

The ingrown nail correction tool listed in Document 2 is also the correction tool previously proposed by the applicant,
A nail tip edge that develops a curved deformed nail is accommodated in the accommodating gap of the substantially U-shaped ingrown nail correction tool having an accommodating gap opened to both ends in the longitudinal direction in which the deformed nail tip edge can be accommodated. In this state, the deformed nail is deformed into a flat shape by plastically deforming the correction tool body from above and below so as to close the storage gap, but the nail side edge is bent. Since it does not have the correction ability to add a means to horizontally deform the deformed portion in the outward direction, the bent deformed portion deformed into an acute angle so as to be further inwardly inserted in the nail groove is pinched. In this case, there is a problem in that the bending deformation part causes a dangerous situation in which the puncture is further deteriorated by crushing inward in a state where a part of the nailfold soft tissue is involved. Further, like the above-mentioned document 1, the bending deformation portion has not yet been found at that time, and there is a problem that a function or means for safely flattening and correcting the bending deformation portion is not provided.

Further, the nail correction tool listed in the above-mentioned document 3 has been previously proposed by the present applicant. At that time, the nail corrector was invented by knowing the bending deformation part and introducing the correction means for the bending deformation part. By inserting into the slit part of the correction tool and sliding sideways to the bending deformation part that has developed the ingrown nail, the effect is that the bending deformation part is hooked and scraped off by the molding side wall provided in the correction tool. can get. However, when the nail thickness is thin or the nail quality is becoming more fragile, when the bending deformation part is hooked on the molding side wall and slid, There is a problem that a dangerous situation that further worsens the symptom is caused, such as peeling a raw nail, missing a nail plate near a bent deformed part, or causing a nail split.

The object of the present invention is to solve these problems and to be buried in a curved deformation site (hereinafter referred to as “first nail deformation site”) which is a first correction purpose and a nailfold soft tissue which is a second correction purpose. Multipurpose nail using pressure flattening that can safely and easily correct and correct nail deformation that has developed in different nail parts such as bending deformation parts (hereinafter referred to as “second nail deformation part”) It is to provide a correction tool.
