Description

  The present invention relates to a device for correcting the deformation of the nail, and particularly, for example, as one of the nail and the other side edge of the nail wraps inwardly as the toenail extends, bites into the meat part between the nail and the fingertip. The present invention relates to a device for correcting the deformation of a nail by a so-called wound nail or the like.

The conventional method of correcting the wound nail as the background of the present invention employs a surgical method for a case where the deformation of the nail is severe, depending on the degree of the wound nail.
However, in the method by surgical operation, the nail that has bitten into the meat part is partially cut and removed, so that it is difficult to perform the operation when there is a risk of bacterial infection. Even if the nail is partially removed by surgical operation and the curled nail is temporarily repaired, the curl nail phenomenon recurs after surgery because the flexibility of the entire nail in the winding direction is not corrected. There was a lot of fear.

On the other hand, in order to repair the wound nail without selecting a surgical operation, for example, a plate-shaped piece made of a shape memory alloy or a shape memory resin is adhered to the bent surface of the wound nail with an adhesive, and the environmental temperature is set. There has been a method of repairing the wound claw by the restoring force of the plate-like piece by raising it to a predetermined temperature or higher.
However, this method is not very effective when the restoring force is outside the range due to the elastic deformation of the shape memory material. In addition, in this method, the plate-shaped piece is adhered to the nail surface with an adhesive, so that the plate-shaped piece is easily peeled off from the nail surface when the adhesive strength of the adhesive is low, and conversely, the adhesive force is too high In such a case, inconveniences such as obstructing the restoring force of the plate-like piece occur.
In addition, as another conventional technology that is the background of the present invention, it is useful to support natural growth of nails by correcting the deformation of nails such as wound nails by a simple method without performing surgical operation. A corrector that corrects the deformation of the nails has been proposed (see, for example, Patent Document 1).
As shown in FIG. 24, the conventional corrector 100 includes a first corrector 120A and a second corrector 120B attached to the nail body A. 120 A of 1st correction bodies are the 1st latching | locking part 122A latched by the one side edge of the nail | claw body A in the width direction, and the 1st contact part 124A contact | abutted on the nail | claw body A surface. And a first connecting hook portion 126A connected to the first contact portion 124A. The second correction body 120B includes a second locking portion 122B that is locked to the other side edge in the width direction of the nail body A, and a second contact portion 124B that is in contact with the surface of the nail body A. And a second connecting hook portion 126B connected to the second contact portion 124B. Between the first connecting hook portion 126A and the second connecting hook portion 126B, a correction operating portion 128 that pulls up both side edge portions of the nail body A in the direction opposite to the deformation direction is disposed.

The straightening operation unit 128 is shown in the figure after the intermediate portion in the longitudinal direction of a tensile force adjusting member 130 (see FIG. 25), which will be described later, is hooked on the first connection hook portion 126A and the second connection hook portion 126B. As shown in FIG. 24, both ends in the length direction of the U-shaped tensile force adjusting member 130 are constituted by winding portions (twisted portions) 132 formed by winding and twisting. The tensile force adjusting member 130 is wound up and twisted by inserting the collar portion b of the twisting tool B into a portion where the insertion rings 119A and 119B are overlapped. At this time, the tension between the first connecting hook portion 126A and the second connecting hook portion 126B is adjusted between the first connecting hook portion 126A and the second connecting hook portion 126B while adjusting the pulling force that pulls up one end side and the other end side in the width direction of the nail body A Is formed.
Furthermore, in this conventional corrector 100, for example, as shown in FIG. 24, the first connecting hook portion 126A and the second connecting hook portion 126B around the correction operating portion 128 are centered on an annular correction operating portion 128. The covering portion 134 is covered over the winding portion 132. The covering portion 134 is formed by applying an ultraviolet curable resin material to the predetermined portion described above and then irradiating the portion with ultraviolet rays for a predetermined time.

For example, as shown in FIG. 26, the conventional corrector 100 is made of two base materials, ie, a base material 102 for corrective body and a base material 104 for corrective action part.
The corrective body base material 102 includes a bus bar 106 having a length direction. A substantially U-shaped convex portion 108 is formed at an intermediate portion in the length direction of the bus bar 106. The convex portion 108 protrudes in a direction substantially orthogonal to the axial direction of the bus bar material 106. An S-shaped bent portion 110 </ b> A is formed between one end of the bus bar 106 in the length direction and the convex portion 108. The S-shaped bent portion 110 </ b> A is disposed on the same plane as the convex portion 108. Similarly, an S-shaped bent portion 110 </ b> B is formed between the other end of the bus bar 106 in the length direction and the convex portion 108.

Further, for example, an inverted U-shaped bent portion 112A is formed between one end of the bus bar 106 in the length direction and one bent portion 110A. The inverted U-shaped bent portion 112A is connected to one end of the previous S-shaped bent portion 110A. The inverted U-shaped bent portion 112A is disposed on a plane substantially orthogonal to the plane on which the convex portion 108 and the S-shaped bent portion 110A are disposed. In this case, the inverted U-shaped bent portion 112 </ b> A extends in a direction perpendicular to the axial direction of the bus bar 106 as viewed in FIG. 26. Similarly, an inverted U-shaped bent portion 112B is formed at one end of the S-shaped bent portion 110B between the other end of the bus bar 106 in the length direction and the other S-shaped bent portion 110B.
The bus bar 106, the convex portion 108, the S-shaped bent portions 110A and 110B, and the inverted U-shaped bent portions 112A and 112B are integrally formed of a metal material having elasticity such as spring steel.

  In the orthodontic body base material 102 described above, the left and right S-shaped bent portions 110A and 110B of the initial base wire 106 are reversed by turning the protrusion 108 toward the toe and then standing substantially vertically upward. The U-shaped bent portions 112A and 112B are positioned. That is, when the convex portion 108 is directed toward the toe, the inverted U-shaped bent portions 112A and 112B are directed to the base (nail root) side of the nail body A in the opposite direction. This convex portion 108 is an arrangement for clarifying the arrangement and direction of the S-shaped bent portions 110A and 110B and the inverted U-shaped bent portions 112A and 112B that form the first correction body 120A and the second correction body 120B. It has a direction indication function.

  On the other hand, as shown in FIG. 26, the straightening operation part base material 104 includes a tensile force adjusting member 130 having an inverted U-shape in plan view and formed of a metal wire having elasticity. The tensile force adjusting member 130 has, for example, an arcuate curved portion 114 at the center in the length direction. Linear leg portions 116A and 116B are formed between one end portion of the tensile force adjusting member 130 and the curved portion 114, and between the other end portion of the tensile force adjusting member 130 and the curved portion 114, respectively. Furthermore, ring-shaped insertion rings 119A and 119B are formed at one end and the other end of the tensile force adjusting member 130 via twisted portions 118A and 118B, respectively. The tensile force adjusting member 130, the torsional portions 118A and 118B, and the insertion rings 119A and 119B are integrally formed of a metal material having elasticity such as spring steel, in the same manner as the correction body base material 12 described above.

Then, next, the formation method which forms 120 A of 1st correction bodies and 2nd correction body 120B with the base material 102 for correction bodies is demonstrated.
First, the convex part 108 of the corrective body base material 102 is held by hand, and the S-shaped bent part 110A is sandwiched and fixed by a needle holder (not shown).
Next, a curve as shown in FIGS. 24 and 25 is obtained by gently bending one side of the length of the bus bar 106 in accordance with the size of the nail body A and the bending condition of the nail body A with a pliers or the like. 136A is formed. Then, the end of the curve 136A is cut with a cutter (not shown) in accordance with the width of the nail body A, and the degree of curvature of the curve 136A is adjusted according to how the nail body A is wound. Further, a U-shaped bent portion 138A is formed by bending a portion of about 5 mm from the tip of the curve 136A, for example, between the bending means C such as pliers and bending the portion inward as shown in FIG.
Thereafter, a portion of about 1 mm, for example, is cut from the tip of the bent portion 138A with a cutter (not shown), so that a first lock having a curve 136A and a bent portion 138A on one side in the length direction of the bus bar 106 is obtained. A portion 122A is formed.
Then, after cutting the S-shaped bent portion 110A at the portion indicated by the alternate long and short dash line xx shown in FIG. 27, a portion of about 0.5 mm from the cut end is further cut by a cutter or the like as shown in FIG. By cutting at D, the first connecting hook portion 126A is formed, and at the same time, the inverted U-shaped bent portion 112A becomes the first contact portion 124A. In this way, the first correction body 120A including the first locking portion 122A, the first contact portion 124A, and the first connection hook portion 126A is formed.
Similarly, a second locking portion 122B having a curve 136B and a bent portion 138B is formed on the other side in the length direction of the bus bar material 106, as shown in FIG. 126B and the second contact portion 124B are formed, and the second correction body 120B including the second locking portion 122B, the second contact portion 124B, and the second connection hook portion 126B is formed. The

Japanese Patent No. 3530901

  However, in the conventional correction tool 100 as shown in Patent Document 1, for example, as shown in FIG. 26, the correction material base material 102 and the correction material for forming the first correction body 120A and the second correction body 120B are used. In addition to the need for the corrective working part base material 104 for forming the working part 128, the first and second locking parts 122A and 122B, the first and second contact parts 124A and 124B, In order to form the first and second connection hook portions 126A and 126B, the step of bending the base wire material 106, as described in the above [Background Art] section, is performed on the correction body base material 102. Processing steps such as a step, a bending step, a bending step, and the like are performed, and the processing step is complicated and requires a high level of technology. For this reason, the mounting method for mounting the conventional corrector 100 to the nail body A is complicated, complicated, and requires a high level of skill, and the mounting work takes a long time.

Further, in this conventional corrector 100, as shown in FIG. 26, an inverted U-shaped bent portion 112A that becomes the first abutting portion 124A and an inverted U-shaped bent portion 112B that becomes the second abutting portion 124B. Then, the S-shaped bent portion 110A that becomes the first connecting hook portion 126A and the S-shaped bent portion 110B that becomes the second connecting hook portion 126B, respectively, Placement and orientation are determined.
Therefore, in this conventional correction tool 100, for example, if the first correction body 120A is compatible with the nail body A and the second correction body 120B is not compatible with the nail body A, another correction is performed. It was necessary to manufacture the second correction body 120B again using the body base material 102. That is, if only one of the first correction body 120A and the second correction body 120B is not compatible with the nail body A, the correction body base material 102 is required separately. In the conventional correction tool 100, the manufacturing cost is high, and the time for attaching the correction tool 100 to the nail body A is further increased.

  Further, in this conventional corrector 100, when the tension adjusting member 130 is twisted by the twisting tool B (see FIG. 24), the tension is adjusted depending on the twist direction of the twisted portions 118A and 118B. There is a possibility that the twisted portions 118A and 118B of the force adjusting member 130 may be loosened and unwound. When such a problem occurs during the mounting operation of the corrector 100 on the nail body A, it is necessary to replace the loosened and unwound tensile force adjusting member 130 with another tensile force adjusting member 130, and the mounting operation time is long. It will be a thing.

Site Further, in the conventional orthotic 100, which Tsu superimposed Tensile (see FIG. 24) when a force adjustment member 130 will rotate twisting in the twisting times instrument B, insertion of the tension adjusting member 130 rings 119A and 119B Further, the work of inserting the collar part b of the twisting tool B is complicated, and it takes a long time for the mounting work.

  Furthermore, in this conventional corrector 100, when the tension adjusting member 130 is twisted with the twisting tool B (see FIG. 24), as shown in FIG. Since the distance r from -x) to the point P where the rotational force is applied is small, the moment of the force around the rotational axis (torsional moment) is small. Therefore, in this conventional correction tool 100, the twisting moment of the twisting tool B is increased by the amount of twisting moment by one twist, that is, the correction tool 100 to the nail body A is increased. As a result, there is a problem that the mounting work time becomes longer.

  Therefore, the main object of the present invention is to provide a device for correcting the deformation of the nail, which has a simple mounting structure on the nail body, which facilitates the mounting work and shortens the mounting work time.

The present invention according to claim 1 is a first locking portion that includes a first locking piece that is formed of an elastic hard wire rod and that is locked to one side edge in the width direction of the nail body. A first abutting surface that abuts against the surface of the nail body, a first supporting portion that supports the first locking portion, a first connecting piece at one end thereof, The first straightening member including the first connecting portion connected to the first support portion, and a hard wire having elasticity, is locked to the other side edge in the width direction of the nail body. A second locking portion provided with a second locking piece; a second support portion that includes a second abutting surface that is in contact with the surface of the nail body and supports the second locking portion; The second straightening member is provided with a second connecting piece including one end of the second connecting piece and the other end connected to the second supporting portion, and a flexible flexible wire. 1st connection piece and 2nd connection A tension member that is hooked on the first connection piece and a portion opposite to the part that is hooked on the first connection piece and the second connection piece.

In this invention concerning Claim 1, the 1st latching piece of a 1st latching | locking part and the 2nd latching piece of a 2nd latching | locking part are respectively the width direction of nail | claw bodies, such as a winding nail | claw. Locked to one end edge and the other end edge. The first contact surface of the first support part and the second contact surface of the second support part are in contact with the surface of the nail body to press the nail body downward. Therefore, the first support member and the second support member stably support the first correction member and the second correction member on the surface of the nail body without shifting. The tensile member is twisted at a portion opposite to the portion hooked on the first connecting piece and the second connecting piece. The correction operation part holds the first locking part and the second locking part in a state of being pulled toward the intermediate part side in the width direction of the nail body with a predetermined tensile force.
At this time, the tensile force due to the twisting of the tension member is input to the first connection piece and the second connection piece that are the power points, and the first contact surface and the second contact surface of the first support part that are the fulcrums. It is output to the first locking piece and the second locking piece, which are the power points, via the second contact surface of the support portion. Therefore, both edge portions in the width direction of the nail body are pulled up in the opposite direction (upward direction) to the winding direction of the wound nail by the tensile force of the correction operation unit, In addition, a tensile force in the direction opposite to the winding direction of the winding claw is continuously applied. This tensile force can be increased by increasing the twisting amount (twisting number) of the tensile member, and conversely, by reducing the twisting amount (twisting number), this tensile force can be reduced. Is possible. In this case, the tensile force due to the twisting of the tension member is appropriately adjusted according to the size and shape of the nail body, the degree of curvature of the wound nail, and the like.
Therefore, according to the device for correcting the deformation of the nail according to the first aspect of the present invention, it is possible to correct and correct the deformation of the nail such as the wound nail.
Further, in the present invention according to claim 1, as compared with Patent Document 1 (prior art), the step of bending, cutting and bending the bus bar material for forming the first correction member and the second correction member There are very few processing steps such as a step of bending and a step of bending, and the processing step is complicated and does not require high technology. Therefore, it is easy to mount the first correction member and the second correction member according to the first aspect of the present invention on the nail body, and the mounting time can be shortened.
Moreover, in the correction tool shown in Patent Document 1 (prior art), as shown in FIG. 26, the members constituting the first correction body and the second correction body are respectively in advance in the base material for the correction body, Since the arrangement and directionality thereof are determined, when the compatibility with the nail body cannot be obtained with only one of the first correction body and the second correction body, the base material for the correction body is separately provided. However, in the present invention according to claim 1, the first straightening member and the second straightening member are each constituted by a single item and are attached to the nail body. Since the directivity and arrangement are not determined in advance, the first correction member and the second correction member can be used in combination with each other. Therefore, compared to the correction tool shown in Patent Document 1 (prior art). , Production cost of first straightening member and second straightening member For cheap, by extension, wear time of the nail of the first straightening member and the second straightening member becomes more even more shorter.
Furthermore, in this invention concerning Claim 1, a loop part is hooked on the 1st connection piece and the 2nd connection piece. For example, by inserting a hook or the like of a twisting means into the insertion ring, the tension member can be easily twisted.
Moreover, in this invention concerning Claim 1, since the tension member has a reach part compared with the correction tool shown, for example in patent document 1 (prior art), it is a tension member using the hook of a twisting means, etc. 14, the distance R from the rotation center (rotation axis xx) of the hook 72 of the twisting means to the point P where the rotational force is applied is the conventional correction tool shown in FIG. Since R> r as compared with r in this case, the force moment (torsional moment) around the rotation axis is large. Therefore, in the present invention according to claim 1, as compared with the conventional correction tool, the twisting moment by the twisting means 72 is less because the twisting moment by one twisting is larger. It is possible to shorten the mounting time of the first correction member, the second correction member, and the tension member, and the formation time of the correction operation portion by the tension member.
The present invention according to claim 2 is an invention dependent on the invention according to claim 1, wherein the loop portion, the insertion ring, and the reach portion each have a form of a front line-of-sight symmetric figure and are symmetrical with each other. The device is a device for correcting the deformation of the nail, characterized in that the axes are arranged on the same axis and the reach part has a predetermined length in a direction orthogonal to the symmetry axis.
Since the present invention according to claim 2 has the above-described configuration, the structure for mounting on the nail body is simpler, the mounting work is easier, and the mounting is easier than the invention according to claim 3. Work time can be shortened.
The present invention according to claim 3 is an invention dependent on the invention according to claim 1 or claim 2, wherein the tension member includes an elliptical loop portion, and the maximum in the minor axis direction of the elliptical loop portion. length, characterized in that it is smaller than half the width direction of the length of the pawl member, a device to fix the deformation of the nail.
In the present invention according to claim 3, for example, compared to the case of using a tension member having a circular loop portion with a circular shape in front view that has the same diameter as the length of the loop portion in the long axis direction, When the loop portion of the tension member is twisted, the length in the minor axis direction of the elliptical loop portion is formed to be shorter than the diameter of the circular ring portion in the front view. The elliptical loop portion has a smaller reaction force applied to the elliptical loop portion and a reaction force moment (torsional moment). Therefore, the oval loop part can more easily rotate the hooks of the twisting means and the like more smoothly than the circular loop part when viewed from the front. Therefore, in the present invention according to claim 3, compared with the invention according to claim 1, the mounting structure to the nail body is further simplified, the mounting work is simplified, and the mounting work time can be shortened. It has become a thing.
The present invention according to claim 4 is an invention dependent on the invention according to any one of claims 1 to 3, wherein each of the first connecting portion and the second connecting portion has a groove portion. A device for correcting the deformation of a nail, comprising a first connecting piece and a second connecting piece.
In this invention concerning Claim 4, a tension member is hooked in a groove part.
The present invention according to claim 5 is an invention dependent on the invention according to any one of claims 1 to 4, wherein the first connecting portion and the second connecting portion are notched portions, respectively. A device for correcting deformation of a nail, comprising a first connecting piece and a second connecting piece having

The loop portion 60 is formed as a soft wire having a predetermined strength by performing annealing treatment and wire drawing processing on a spring stainless steel wire or the like as a soft wire material having elasticity.
First, the loop portion 60 intersects one end side and the other end side in the length direction of the above-described soft wire, and sandwiches the intersecting end portion (not shown) with a clamping means (not shown) such as a nipper. The twisted portion 60B is formed at the intersecting end portion (not shown) by rotating, for example, thereby forming an elliptical loop portion main body 60A [see FIG. 3A].
Next, the twisted part 60B of the loop part main body 60A has an appropriate part of the twisted part 60B by cutting means (not shown) such as a cutter as shown in FIG. Disconnected. The twisted portion 60C remaining in the loop portion main body 60A becomes the loop portion intersection end portion of the loop portion main body 60A.
After that, as shown in FIG. 4A, the twisted portion 60C is bent along the circumferential direction of the loop portion main body 60A to become a twisted portion bent piece 60D. The twisted portion bending piece 60D and the circumferential portion 60E of the loop portion main body 60A overlapped with the twisted portion bending piece 60D serve as a reach portion attaching portion 65 for attaching a reach portion 64 described later. .

Next, the reach ring 64 attached to the insertion ring 62 and the reach part attachment site 65 described above will be described in detail below with reference to FIGS. 2 and 4B and 4C.
That is, the insertion ring 62 includes, for example, a ring main body 62A that is circular when viewed from the front. In particular, as shown by the two-dot chain lines in FIGS. 4B and 4C, for example, a bent front-view horizontally long bent plate 66 is disposed on a part of the ring body 62A in the circumferential direction. Has been. The ring body 62A and the bending plate 66 are integrally formed of a rigid metal material such as stainless steel.
Further, as shown in FIGS. 4B and 4C, the bending plate 66 is clamped by the above-described reach plate attaching portion 65, and then the bending plate 66 is caulked, for example. 66 and the reach part attaching part 65 are closely attached and fixed.

Next, the first correction member 12 and the second correction member 14 of the device 10 for correcting the deformation of the nail according to the present embodiment are used to correct the deformation of the nail such as the wound nail. Hereinafter, an example of a method (usage method) of attaching the correction member 12 and the second correction member 14 to the nail body A will be described in detail with reference to FIGS.
A first correction member 12 and a second correction member 14 are prepared. The nail body A is preliminarily sterilized in advance.
First, for example, the first locking portion 18 of the first correction member 12 is held between the needle holders 70, and as shown in FIGS. 5 and 6, the nail groove on the one end edge side in the width direction of the nail body A is formed. The first locking piece 16 is locked at approximately one third of the position from the nail mother (nail root side). This is because if the locking position of the first locking piece 16 is too close to the nail mother (nail root side), the nail formation may be affected. Similarly, on the other end edge side of the nail body A in the width direction, as shown in FIGS. 5 and 6, the second locking piece 28 of the second correction member 14 is arranged in the width direction of the nail body A. The nail groove (nail base side) of the nail groove on the other edge side is locked at approximately one third of the position.

Next, the first locking piece 16, the second locking piece 28 and the periphery thereof are pressed by the fingertip of one hand, and the loop portion 60 of the tension member 40 is held by the fingertip of the other hand. As shown in FIG. 4, the hook 24A of the first connecting piece 24 and the hook 36A of the second connecting piece 36 are hooked.
Then, the hook 72 of the twisting means is hooked on the insertion ring 62 of the tension member 40, for example, as shown in FIG. The first connecting piece 24 is twisted up and twisted toward the center between the hook 24A of the first connecting piece 24 and the hook 36A of the second connecting piece 36.

  When the loop portion 60 is appropriately twisted to a desired twist amount (twist number) and tension is applied to the first locking piece 16 and the second locking piece 28, Holding the (twist up part) with a finger, the hook 72 of the twisting means is swung in the vertical and horizontal directions of the nail body A as shown by the two-dot chain arrows in FIG. Then, it is checked whether the second correction member 14 is firmly attached to the nail body A. In addition, when the 1st correction member 12 and the 2nd correction member 14 wobble and are tightened loosely, the hook 72 of a twisting means is rotated again and the loop part 60 is retightened. When the 1st correction member 12 and the 2nd correction member 14 move to the base side of the nail | claw body A integrally, the said loop part 60 is twisted correctly, and the 1st correction member 12 and the 2nd It is determined that the correction member 14 is securely attached to the nail body A.

Next, when the first straightening member 12 and the second straightening member 14 are firmly attached to the nail body A and the twisting step is completed, as shown in FIG. The base side of the portion (screw-up portion) 76 is cut. In this case, the twisted portion (twisted-up portion) 76 is left on the base side, for example, by 1 to 3 turns, and the remaining portion is cut.
As a result, as shown in FIG. 9, the first locking portion 18 and the second locking portion 30 are disposed on the intermediate portion side in the width direction of the nail body A at the substantially central portion in the width direction of the nail body A. While being held in a state of being pulled by a predetermined tensile force, in this state, a correction operation unit 42 that connects the first correction member 12 and the second correction member 14 is formed.
In this embodiment, for example, as shown in FIG. 6, when the lateral width of the nail A is L, the distance between the center of the first support portion 22 and the center of the second support portion 34 is L / 3. The size of the 1st correction member 12 and the 2nd correction member 14 is set so that it may become. In addition, between the front-end | tip part of the hook 24A of the 1st connection piece 24, and the front-end | tip part of the hook 36A of the 2nd connection piece 36, or the bending end part of the 1st connection piece 24, and the bending of the 2nd connection piece 36 The size of the first correction member 12 and the second correction member 14 may be set so that the distance between the end portions is L / 3.

  Further, as shown in FIG. 10, so as to cover the correction operating part 42, the first connecting part 26, the second connecting part 38, the first supporting part 22, the second supporting part 34 and the periphery thereof, For example, a paste-like ultraviolet curable resin material as a coating material is applied by an application means 78 such as a brush, or directly applied from a container (not shown) such as a tube containing the coating material. Thus, the application portion 44A is formed. In this case, if air bubbles enter the application portion 44A, cracks and the like are likely to enter the application portion 44A and break easily. Therefore, when applying the coating material with the application means 78, carefully apply the coating material so that bubbles do not enter. Applied.

Further, as shown in FIG. 11, the coating part 44 </ b> A is irradiated with ultraviolet rays by a UV LED (ultraviolet light emitting diode) 80, for example, for a predetermined time, for example, 20 seconds. As a result, the coating portion 44A is cured, and a covering portion 44 is formed as shown in FIG. The covering portion 44 protects the straightening operation portion 42 and the periphery thereof, and at the same time, strengthens the coupling force between the first straightening member 12 and the second straightening member 14, and stabilizes the coupling force. Can be held.
Note that the application region of the application unit 44A is not limited to the above-described one, and may include at least the correction operation unit 42, the first connection unit 26, and the second connection unit 38 as shown in FIG. That's fine.

  In the embodiment described above, for example, as shown in FIGS. 8, 9, and 12, the first locking piece 16 of the first locking portion 18 and the second locking of the second locking portion 30. The pieces 28 are respectively locked to one end edge portion and the other end edge portion in the width direction of the nail body A such as a wound nail. The first contact surface 20 of the first support portion 22 and the second contact surface 32 of the second support portion 34 are in contact with the surface of the nail body A and press the nail body A downward. To do. Therefore, the first support member 22 and the second support member 34 stably support the first correction member 12 and the second correction member 14 on the surface of the nail body A without shifting. .

For example, as shown in FIGS. 7 and 8, the tension member 40 is twisted at a portion opposite to the portion hooked by the first connecting piece 24 and the second connecting piece 36. For example, as shown in FIGS. 9 and 12, the correction operating portion 42 pulls the first locking portion 18 and the second locking portion 30 toward the intermediate portion in the width direction of the nail body A with a predetermined tensile force. Hold in a pressed state.
At this time, for example, as shown in FIG. 8, the tensile force due to the twisting of the tension member 40 is input to the first connection piece 24 and the second connection piece 36 that are the power points, and the first support portion that is the fulcrum. 22 is output to the first locking piece 16 and the second locking piece 28, which are the power points, via the first contact surface 20 of 22 and the second contact surface 32 of the second support portion 34. . Therefore, both edge portions in the width direction of the nail body A are pulled up in the direction (upward) opposite to the winding direction of the nail body A such as a wound nail by the tensile force of the correction operation unit 42, and the width direction of the nail body A A tensile force in the direction opposite to the winding direction of the nail body A is continuously applied to both end edges. This tensile force can be increased by increasing the twisting amount (twisting number) of the tension member 40, and conversely, by reducing the twisting amount (twisting number), this tensile force can be reduced. Can do. In this case, according to the size and shape of the nail body A, the degree of curvature of the wound nail body A, etc., the tensile force due to the twisting of the tension member 40 is appropriately adjusted.
Therefore, according to the device 10 according to the present embodiment, the deformation of the nail body A such as the wound nail can be corrected.

  Furthermore, in this embodiment, for example, as compared with Patent Document 1 (prior art), a step of bending, cutting, and bending a bus bar for forming the first correction member and the second correction member Further, there are very few processing steps such as a bending step, and the processing steps are complicated and do not require high-level technology. Therefore, in the present embodiment example, the first correction member 12 and the second correction member 14 can be easily mounted on the nail body A, and the mounting time can be shortened.

  On the other hand, in the corrector 100 shown in Patent Document 1 (prior art), as shown in FIG. 26, for example, the members constituting the first corrector 120A and the second corrector 120B are the corrector base materials. In 102, since the arrangement and directionality are determined in advance, if only one of the first correction body 120A and the second correction body 120B is not compatible with the nail body A, In addition, while the correction body base material 102 is separately required, in the apparatus 10 according to the present embodiment, the first correction member 12 and the second correction member 14 are each configured as a single item. In addition, the directionality and arrangement when attaching to the claw body A are not determined in advance. In this case, since the 1st correction member 12 and the 2nd correction member 14 can mutually be used, compared with the conventional correction tool 100 shown, for example in FIG. The manufacturing cost of the straightening member 14 is reduced, and as a result, the mounting time of the first straightening member 12 and the second straightening member 14 to the nail body A is further shortened.

  Further, in the present embodiment example, since the tension member 40 has the reach part 64 in particular as compared with the correction tool 100 shown in Patent Document 1 (prior art), the tension member 40 is pulled using the hook 72 of the twisting means. When the member 40 is twisted, for example, as shown in FIG. 14, the distance R from the rotation center (rotation axis xx) of the hook 72 of the twisting means to the point P where the rotational force is applied is, for example, in FIG. Compared to r in the case of the conventional corrector 100 shown in the figure, since R> r, the moment of force (torsional moment) around the rotation axis xx is large. Therefore, in the device 10 according to the present embodiment, the twisting moment by the twisting means 72 is less than the conventional straightening tool 100 because the twisting moment by one twisting is larger. The mounting time of the first correction member 12, the second correction member 14, and the tension member 40 and the formation time of the correction operation part 42 by the tension member 40 can be shortened.

Further, in the case of the correction tool 100 shown in Patent Document 1 (prior art), as shown in FIGS. 24 and 15, the tensile force adjusting member 130 is twisted by rotating the collar b of the twisting tool B. Sometimes, a twisting moment acts on the twisted portions 118A and 118B, and the twisted portions 118A and 118B may be twisted.
In contrast, in this embodiment, when the loop portion 60 of the tension member 40 is twisted by rotating the hook 72 of the twisting means, the loop portion 60 is directly twisted via the reach portion 64. Since it is configured to rotate, there is no fear of twisting the loop portion 60.
Further, in the case of the correction tool 100 shown in Patent Document 1 (prior art), as shown in FIGS. 24 and 15, the tensile force adjusting member 130 is twisted by rotating the collar b of the twisting tool B. In some cases, the twisted portions 118A and 118B of the tensile force adjusting member 130 may be loosened and untwisted depending on the twist direction of the twisted portions 118A and 118B.
In contrast, in this embodiment, when the loop portion 60 of the tension member 40 is twisted by rotating the hook 72 of the twisting means, the loop portion 60 is directly twisted via the reach portion 64. Since the twisted portions 118A and 118B are not twisted as described above, it is possible to prevent the occurrence of the above-described problems. Therefore, in this embodiment, it is not necessary to replace the tension member 40 with another tension member 40 during the mounting operation of the correction tool 100 on the nail body A, and the mounting operation time can be shortened as compared with the conventional technique described above. .

FIG. 16 is a view showing another example of the tension member that can be applied to the device for correcting the deformation of the nail of the present invention, and is a view showing an installation example of the tension member, and FIG. It is a principal part perspective view which shows the example of mounting | wearing in case the distance between the 1st connection part and the 2nd connection part of a 2nd correction member is long, Comprising: (B) is the said 1st connection part and 2nd It is a principal part perspective view which shows the example of mounting | wearing when the distance between connection parts is short.
In the embodiment described above, the loop portion 60 of the tension member 40 is formed in an elliptical loop portion. However, in the embodiment shown in FIGS. The portion 61 may be formed. In this case, by forming the diameter of the loop portion 61 to be approximately the same length as the lateral width of the nail body A, the first connecting portion 24 of the first correction member 12 and the second of the second correction member 14 are formed. Even when the distance between the connecting portions 28 is long as shown in FIG. 16A or when the distance is short as shown in FIG. According to the width of A, it is excellent in versatility without the need to replace the tension member 40.
However, from the viewpoint of so-called versatility that it is possible to flexibly cope with the difference in the width of the nail body A, the loop portion of the tension member 40 is shown in FIGS. 16A and 16B. Although it is preferable to form the loop portion 61 having a circular shape when viewed from the front as in the embodiment, for example, as shown in FIGS. 6, 7, and 8, the tension member 40 is rotated by the rotation of the hook 72 of the twisting means. When the loop part 60 is twisted, when the length of the long axis direction of the loop part 60 and the diameter of the loop part 61 are set to be the same, the length of the short axis direction of the loop part 61 is larger than the diameter of the loop part 60. 6 is shorter than the above-described circular loop portion 61 in front view, the elliptical loop portion 60 shown in FIG. 6 has a reaction force applied to the loop portion 60 and a moment of reaction force ( (Torsion moment) is small. Therefore, the elliptical loop portion 60 can more easily rotate the hook 72 of the twisting means and perform the twisting operation more smoothly than the loop portion 61 that is circular in a front view.

The difference between the first correction member 12 and the first correction member 12 applied to the embodiment shown in FIGS. 17 to 19 will be described, and the description of the difference from the second correction member will be omitted.
In the first straightening member 12 shown in FIGS. 17A and 17B, in particular, the first locking portion 18 has a linear portion 46, compared to the first straightening member 12 shown in FIG. The arcuate portion 49 and the first locking piece 16 are not formed. In this case, the arcuate part 49 is formed to have a larger radius of curvature and a smaller curvature than the arcuate part 48 shown in FIG. Therefore, it is possible to flexibly cope with the difference in the degree of curvature of the nail body A.
Moreover, in the 1st correction member 12 shown to FIG. 18 (A), (B), compared with the 1st correction member 12 shown, for example in FIG. The piece 16 is not provided, and the first locking portion 18 is formed by the arc-shaped portion 57 and the linear portion 59. The 1st latching piece 16 becomes a mode formed in the linear part 59 at a post process. Also in this case, it is possible to flexibly cope with the difference in the degree of curvature of the nail body A.
Further, in the first straightening member 12 shown in FIGS. 19A and 19B, the first locking portion 18 is particularly a linear portion 47 as compared with the first straightening member 12 shown in FIG. 1, for example. Just formed. The 1st latching piece 16 becomes a mode formed in the linear part 47 at a post process. Also in this case, it is possible to flexibly cope with the difference in the degree of curvature of the nail body A.

It is AA sectional drawing. In addition, since the 1st correction member 12 and the 2nd correction member 14 have the same structure, an effect | action, and an effect, in the following description, only the 1st correction member 12 is demonstrated and the 2nd correction member 14 is demonstrated. The description of is omitted.
In the first straightening member 12 shown in FIGS. 20A and 20B, in particular, the first connecting portion 26 becomes the first support portion 22 as compared with the first straightening member 12 shown in FIG. It differs in that it is arranged. That is, the first support portion 22 includes, for example, a plate-like portion 81 having a circular shape in plan view, and the first connecting portion 26 is formed on the upper surface of the plate-like portion 81. The first connecting portion 26 includes, for example, a first connecting piece 82 having an L-shaped cross section. One end (base end) of the first connecting piece 82 is connected to the upper surface of the plate-like portion 81, and the other end (tip) is arranged toward the first locking portion 18 described later. The 1st connection piece 82 is arrange | positioned on the center axis line of the 1st latching | locking part 18 mentioned later. Under the first connecting piece 82, a gap 83 is formed between the upper surface of the plate-like portion 81, and the loop portion 60 of the tension member 40 according to the above-described embodiment is hooked on the gap 83.
