した時に激しい痛みを生じる。FIG. 21 (a) shows a state in which the side edge of the nail 2 is bent inward as compared with a normal nail 2A shown by a chain line, and FIG. 21 (b) shows a more severe depression. It shows a claw, and the degree of bending of the claw 2 is further increased. Such an ingrown nail causes severe pain when the sock is put on the foot and the finger 1 is strongly pressed.

イの全体を爪２の表面に接着する。The following method is one of the methods for treating ingrown nails. As shown in FIG. 22, a straightening tool a made of a plate having a length about the width of the claw 2 entirely formed of a spring material made of special steel or synthetic resin is used. Apply adhesive. Then, the correction tool (i) is placed at the center of the surface of the nail (2), and then the stick (2) is pressed to bond the entire correction tool (1) to the surface of the nail (2).

部を正常になるように矯正する作動が行われる。At this time, the correction tool (i) is adhered to the nail 2 in a forcibly curved shape according to the shape of the surface of the nail 2. For this reason, the elastic tool a generates an elastic restoring force that tends to return to the original shape. This elastic restoring force acts on the nail 2 to correct the indented portion of the nail 2 so as to be normal.

せて湾曲させる必要がある。However, in such a conventional correction tool for an ingrown nail, directly attaching a member having elastic characteristics to the nail involves a troublesome work. For example, when the orthodontic appliance is adhered to the nail with an adhesive, the orthodontic appliance needs to be pressed until it is adhered, and the orthodontic appliance needs to be curved according to the curvature of the nail.

て、爪の陥入部に痛みが発生することがある。Further, since the conventional correction tool for ingrown nail is entirely formed of metal or synthetic resin, the elastic force of the metal or synthetic resin in the correction tool is directly applied to the nail as a correction force. To work. That is, the conventional correction tool tries to correct the indentation so as to be flat by applying a large elastic force per unit area to the nail. Therefore, the nail receives a large force per unit area by the correction tool and is bent in the correction direction. As a result, the ingrown part of the nail may be unreasonably (largely) burdened with the correction tool, and pain may occur in the ingrown part of the nail.

のである。The external force and the elongation in a metal having a superelastic effect are defined as a metal stored so as to recover the shape at a certain temperature (transformation point), for example, a temperature lower than room temperature, at a temperature higher than the transformation point, for example, room temperature. There is a relationship that when the metal is deformed by applying an external force and then the external force is removed, the metal returns to its original shape at room temperature. Therefore, a metal having a superelastic effect, even if deformed at a temperature higher than the transformation point, for example, room temperature,
By removing the external force, the original shape that was memorized is restored.

Is attached to the surface of the nail 2 of the finger 1 by, for example, an adhesive 14. The adhesive 14 is one that does not adversely affect the nail 2 and the human body. Then, the force to restore the original shape of the corrective body 12 acts on the nail 2 via the support body 11. That is, the correction body 12 acts on the nail 2 via the support body 11 to correct the invaded portion 2a. The correction tool can be easily and easily attached to the nail with a correction tool capable of correcting the nail without difficulty.

The load-displacement curves of Cr-based alloys are shown. The shape of the load-displacement curve differs slightly between stainless steel and Co-Cr alloy alloys due to their mechanical properties, but when bent to a certain point (here, it is flexed by 2 mm), it gradually loosens. , The load decreases as the displacement recovers as shown by the downward arrow. This part becomes the correction force. The difference between the load-displacement curve of the stainless steel in FIG. 15 and the load-displacement curve of the Co—Cr alloy is that the permanent strain is large because the yield carbon of the load-displacement curve of the Co—Cr alloy is low.

However, the change in restoring force during unloading is small and a nearly constant force can be obtained over a wide range. Since the absolute value of the force is small, 3-4 Ni-Ti alloy wires having the same wire diameter correspond to two stainless steels when a force is desired.
