Description

  The present invention relates to a curly nail correction tool that is attached to a nail, particularly a nail of a big toe, and corrects the curly nail, and a traction member used for the same.

  Surgery is known as a means for correcting the ingrown nail, but a nail correction tool (see, for example, Patent Document 1) has been proposed as a means for correcting the ingrown nail relatively easily without performing surgery. Yes.

  This is composed of three members, a first straightened body, a second straightened body and a straightening operation part, and these three members are constructed by bending or bending one wire-like member. In addition, the first two correction bodies and the second correction body are formed in substantially the same manner.

  In the first correction body, the first locking portion is locked to one side edge of the nail, the first contact portion is contacted to the surface of the nail, and the first connecting hook portion is the nail. It is arrange | positioned in the center vicinity. Similarly, the second correction body has a second engaging portion that is engaged with the other side edge of the nail, a second abutting portion that is in contact with the surface of the nail, and a second connecting hook. The part is arranged near the center of the nail. In this state, the correction operation part is engaged with the first connection hook part and the second connection hook part, and pulls them toward the center.

  As a result, the incurvated nail corrector has the first engaging portion and the second engaging portion so that one side edge and the other side edge of the nail are opposite to the winding direction of the ingrown nail. Pull up to correct the wound nails.

JP 2001-276104 A

  However, in the above-described ingrown nail correction tool, the first correction body and the second correction body are composed of a single wire-like member as a whole, and thus have the following problems.

That is,
(1) Since one side edge and the other side edge of the claw are towed by a single single wire-like member, the pulling force is relatively low. For this reason, for example, sufficient effects cannot be obtained for thick and hard nails. Note that “relative” means that it is compared with the present invention described later.
(2) Since one side edge of the claw, the first locking part hooked on the other side edge, and the second locking part are also one wire-like member, this one wire-like member Through this, the traction force locally acts on a narrow range of one side edge and the other side edge. For this reason, it is difficult for the traction force to act on the distal end portion and the proximal end portion of the nail. Further, since the traction force acts locally, for example, when the nail is thin, unnecessary deformation may occur in the nail. Furthermore, when the claw is extremely thin, there is a possibility that the claw at the portion where the first locking portion and the second locking portion are caught may be torn.
(3) Since the tips of the first locking portion and the second locking portion formed by one single wire-like member are inserted between the nail and the nail bed, the insertion portion There is a risk of damaging the floor. In extreme cases, bleeding and pain may occur.
(4) Since a single single wire-like member tends to be insufficient in strength, it can be inserted to prevent the first locking portion and the second locking portion from coming off from the side edge of the nail. Although it is necessary to make the length of the portion relatively long, in this case, there is a possibility that the pain is further increased.

  The present invention has been made in view of the above-described circumstances, and has solved the above-mentioned (1) to (4). That is, the traction force can be increased and locally applied to the side edge of the nail. Provided is a curly nail corrector that can prevent a traction force from acting on the insertion member and reduce the length of the insertion portion, and that does not damage the nail bed by the insertion portion, and a traction member used therefor It is for the purpose.

  According to a first aspect of the present invention, there is provided an incurvated nail correction tool for applying a force in a direction opposite to a winding direction to a wound nail by engaging the left end edge and the right end edge of the nail and pulling at the center of the nail.

A first traction member having a first hook portion located in the vicinity of the center of the nail continuously with the first spring portion, and is bent or curved from the front surface side to the back surface side of the nail and engages with the right edge of the nail A second locking portion, a second spring portion extending toward the center of the claw continuously from the second locking portion, and a second spring positioned in the vicinity of the center of the claw continuously from the second spring portion. A second traction member having a hook portion, the first hook portion and the second hook portion are engaged, and the first hook portion and the second hook portion are engaged. And a connecting member that pulls the center portion toward the center to generate a pulling force on the first spring portion and the second spring portion, wherein the first pulling member bends one wire-like member or In addition to being configured to be doubled by bending, a first folded portion is provided at an insertion portion inserted between the nail and the nail bed at the tip of the first locking portion, and the second pulling member is A single folded wire-shaped member is doubled and bent, and the second folded portion is inserted into the insertion portion inserted between the nail and the nail bed at the tip of the second locking portion. Is provided.

  According to a second aspect of the present invention, in the ingrown nail correction tool according to the first aspect, the first hook portion has one end portion and the other end portion of the wire-like member positioned at the tip, The two hook portion is characterized in that one end portion and the other end portion of the wire-like member are located at the tip.

<Embodiment 1>

With reference to FIGS. 1-7, the curl nail corrector 1 which concerns on Embodiment 1 to which this invention is applied is demonstrated.
Among these, FIG. 1 is a perspective view showing the entire curled nail correction tool 1 in a state of being mounted on the nail N (used state). 2A is a top view of the first pulling member 10 (second pulling member 20), FIG. 2B is a side view of the same, and FIG. 2C is a bottom view of the same.

  Hereinafter, a case where the nail N is the nail of the thumb F of the left foot will be described as an example. Further, regarding the nail N, the left edge is the left edge Na, the right edge is the right edge Nb, the tip vicinity is the tip end Nc, and the base vicinity is the base end Nd. In addition, what is called a winding nail | claw has generate | occur | produced in this nail | claw N, and the left end edge Na and the right end edge Nb shall be curving so that it may be curled inwardly (lower side).

  As shown in FIG. 1, the ingrown nail corrector 1 includes a first traction member 10, a second traction member 20, and an annular member 30 as a connecting member. As will be described later, the curly nail corrector 1 is mounted between the left end edge Na and the right end edge Nb of the nail N so as to cross the nail N in the left-right direction (width direction).

  The first pulling member 10 is used by bending one long wire-like member W into two at the center (center) in the length direction and using it as two (double). The first locking part 11, the first spring part 12, and the first hook part 13 are formed by bending. For this reason, all of these 1st latching | locking parts 11, the 1st spring part 12, and the 1st hook part 13 are comprised by the double wire-shaped member W, ie, two pieces.

  Here, the 1st spring part 12 is comprised by the substantially planar shape, and let this be the reference plane H (refer FIG. 2 (B)). The reference surface H is a surface that gently curves by contacting (contacting) the surface of the nail N when the curled nail correction tool 1 is mounted on the nail N. A line that is on the reference plane H and passes through the center of the first pulling member 10 in the front-rear direction is defined as a reference line C (see FIGS. 2A and 2C). This reference line C is a straight line connecting the first locking portion 11 and the first hook portion 13.

  The first locking portion 11 has one end (left end) of the first pulling member 10 bent or curved downward from the reference surface H (from the front surface side to the back surface side of the nail N). It is formed so that the side faces the other end of the first pulling member 10.

  The insertion portion 11a at the distal end of the first locking portion 11 is a folded portion Wa formed by bending or bending the center of one wire-like member W forming the first pulling member 10, and FIG. As shown in C), it is a semicircular smooth curve. Therefore, unlike the conventional case where the tip is pointed, the first locking portion 11 is locked to the left end edge Na of the nail N in order to attach the curled nail correction tool 1 to the nail N. ), The folded portion 11a at the tip of the first locking portion 11 is not likely to damage the nail bed (the portion on which the nail N above the thumb F is placed). Further, unlike the conventional case, the first locking portion 11 is configured by doubling one wire-like member W, that is, it is substantially constituted by two wire-like members W and has strength. Since it is high, it is possible to shorten the length L of the 1st latching | locking part 11, and this can also reduce a possibility of damaging a nail bed.

  The first spring portion 12 is formed in an “∞” shape having a first intersecting portion 12a and two first loop-shaped portions 12b, and as a whole, has a substantially planar shape with the reference plane H as a reference. It is configured. Here, the term “substantially planar” means that one of the double (two) wire-like members W is three-dimensionally crossed on the lower side and the other on the upper side in the first intersecting portion 12a.

  Here, the “∞” shape means that the two first loop portions 12b are connected via the first intersecting portion 12a, and the shape of the two first loop-shaped portions 12b is appropriate. Any shape can be used as long as it can exert a pulling force (traction force). In the example shown in FIG. 2, the two first loop-shaped portions 12 b are formed in a substantially diamond shape. The other shapes of the two first loop-shaped parts 12b will be described later with reference to FIG.

  The first locking portion 11 described above is connected to a portion of the first spring portion 12 that is far from the first intersecting portion 12a in one (left side) first loop-shaped portion 12b.

  The first spring portion 12 is deformed to generate a pulling force (traction force) when the first locking portion 11 and the first hook portion 13 are pulled in opposite directions.

The first spring portion 12 is not configured so that two wire-like members W are adjacent to each other, but the two wire-like members W substantially form a loop, It can be said that the structure is doubled.
The first hook portion 13 is bent or curved with the other end portion (right end portion) of the first pulling member 10 facing upward from the reference plane H (so as to rise upward from the surface side of the nail N), The side is formed so as to face one end (left end portion) of the first pulling member 10.

As for the 1st hook part 13, one edge part W1 and the other edge part W2 of the one wire-shaped member W are match | combined in the front-end | tip 13a.
The first hook portion 13 is engaged with an annular member 30 described later.

  As described above, the first pulling member 10 has the first locking portion 11, the first spring portion 12, and the first hook portion 13, and as shown in FIG. When attached to the claw N, the first locking portion 11 is locked to the left end edge Na of the claw N, the first hook portion 13 is engaged with the annular member 30, and the first spring portion 12 is the first engagement. The stopper 11 and the first hook 13 are pulled (pulled) in a direction approaching.

  The second pulling member 20 is formed in the same shape as the first pulling member 10 described above.

  That is, the second pulling member 20 is used by bending one long wire-like member W into two at the center (center) in the length direction and using it as a double (double). The second locking portion 21, the second spring portion 22, and the second hook portion 23 are formed by bending or curving. For this reason, all of these 2nd latching | locking parts 21, the 2nd spring part 22, and the 2nd hook part 23 are comprised by the wire-shaped member W for 2 pieces, ie, two pieces.

  Here, the 2nd spring part 22 is comprised by the substantially planar shape, and let this be the reference plane H (refer FIG. 2 (B)). The reference surface H is a surface that gently curves by contacting (contacting) the surface of the nail N when the curled nail correction tool 1 is mounted on the nail N. A line that is on the reference plane H and passes through the center of the second pulling member 20 in the front-rear direction is referred to as a reference line C (see FIGS. 2A and 2C). This reference line C is a straight line connecting the second locking portion 21 and the second hook portion 23.

  The second locking portion 21 bends or curves one end portion (right end portion) of the second pulling member 20 downward from the reference plane H (from the front surface side to the back surface side of the nail N). It is formed so that the side faces the other end of the second pulling member 20.

  The insertion portion 21a at the distal end of the second locking portion 21 is a folded portion Wa formed by bending or bending the center of one wire-like member W forming the second pulling member 20, FIG. As shown in C), it is a semicircular smooth curve. For this reason, unlike the conventional case where the tip is pointed, the second locking portion 21 is locked to the right edge Nb of the nail N in order to attach the curled nail correction tool 1 to the nail N. ), The folded-back portion 21a at the tip of the second locking portion 21 is not likely to damage the nail bed (the portion on which the nail N above the thumb F is placed). Further, unlike the conventional case, the second locking portion 21 is formed by doubling one wire-like member W, that is, it is substantially constituted by two wire-like members W and has a strength. Therefore, the length L of the second locking part 21 can be shortened, and this can also reduce the risk of damaging the nail bed.

  The second spring portion 22 is formed in an “∞” shape having a second intersecting portion 22a and two second loop-shaped portions 22b, and has a substantially planar shape as a whole with respect to the reference plane H described above. It is configured. Here, the term “substantially planar” means that one of the double (two) wire-like members W is three-dimensionally crossed on the lower side and the other on the upper side in the second intersecting portion 22a.

  Here, the “∞” shape means that the two second loop portions 22b are connected via the second intersecting portion 22a, and the shape of the two second loop portions 22b is appropriate. Any shape can be used as long as it can exert a pulling force (traction force). In the example shown in FIG. 2, the two second loop-shaped portions 22b are formed in a substantially rhombus shape. Note that other shapes of the two second loop-shaped portions 22b will be described later with reference to FIG.

  The second locking portion 21 is connected to a portion of the second spring portion 22 that is far from the second intersecting portion 22a in one (right side) second loop-shaped portion 22b.

  The second spring portion 22 is deformed to generate a pulling force (traction force) when the second locking portion 21 and the second hook portion 23 are pulled in opposite directions.

The second spring portion 22 is not configured so that the two wire-like members W are adjacent to each other, but the two wire-like members W substantially form a loop, so that It can be said that the structure is doubled.
The second hook portion 23 is bent or curved with the other end portion (left end portion) of the second pulling member 20 directed upward from the reference plane H (so as to rise upward from the surface side of the nail N). It is formed so that the side is directed to one end (right end) of the second pulling member 20.

  As for the 2nd hook part 23, one edge part W1 and the other edge part W2 of one wire-like member W are match | combined in the front-end | tip 23a.

  The second hook portion 23 is engaged with an annular member 30 described later.

  As described above, the second pulling member 20 has the second locking portion 21, the second spring portion 22, and the second hook portion 23. As shown in FIG. When attached to the claw N, the second locking portion 21 is locked to the right end edge Nb of the claw N, the second hook portion 23 is engaged with the annular member 30, and the second spring portion 22 is the second engagement. The stopper 21 and the second hook 23 are pulled (pulled) in a direction approaching.

  FIG. 3 is a top view illustrating the annular member 30.

  As shown in FIGS. 1 and 3, the annular member 30 as the connecting member can be formed of, for example, a metal rod-like member M that is thicker than the wire-like member W and can be plastically deformed. The annular member 30 is formed by bending the central portion M1 of the rod-like member M in an annular shape and overlapping one end M2 and the other end M3.

  The annular member 30 can be changed in size, in particular, the length D in the left-right direction shown in FIG. 3, using pliers or nippers, for example. When the curled nail corrector 1 is attached to the nail N, it opens in the left-right direction to shorten the length of the overlapping portion of the end portions M2, M3, thereby increasing the length D. In this state, the first hook portion 13 of the first pulling member 10 and the second hook portion 23 of the second pulling member 20 are locked to the annular member 30, and then the length D is shortened. By adjusting the length D at this time, the pulling force by the first pulling member 10 and the second pulling member 20 can be easily adjusted.

  The ingrown nail correction tool 1 having the above-described configuration is attached to the nail N as follows and used for correcting the ingrown nail.

  First, the first locking portion 11 of the first pulling member 10 is hooked on the left end edge Na of the claw N, and the first spring portion 12 is directed so that the two first loop-shaped portions 12b and 12b are aligned in the left-right direction. And place on the surface of the nail N. As a result, the first hook portion 13 is positioned on the left side of the center of the claw N in the left-right direction.

  The same applies to the second pulling member 20. That is, the second locking portion 21 of the second pulling member 20 is hooked on the right end edge Nb of the claw N, and the second spring portion 22 is directed so that the two second loop-shaped portions 22b and 22b are aligned in the left-right direction. And place on the surface of the nail N. Thereby, the 2nd hook part 23 is located in the right side rather than the center of the left-right direction of the nail | claw N. FIG.

  The annular member 30 is hooked on the first hook portion 13 and the second hook portion 23.

The annular member 30 is spread a little larger so that the length D becomes longer, and this is hung on the first hook portion 13 and the second hook portion 23. Thereafter, the annular member 30 is contracted so that the length D is shortened using pliers, nippers, or the like. Thereby, the 1st spring part 12 and the 2nd spring part 22 are pulled, and tensile force generate | occur | produces. The pulling force can be adjusted by adjusting the amount by which the annular member 30 shrinks.
Thereafter, an adhesive is applied to the entire ingrown nail corrector 1, and the tips of the wire rod W constituting the first traction member 10 and the second traction member 20 and the tip of the metal rod M constituting the annular member 30 are sharpened. So that they do not get caught in socks, footwear, or bed sheets.

  This completes the mounting of the curly nail corrector 1 on the nail N.

The above-described ingrown nail correction tool 1 can exhibit the following actions and effects.
(1) Since the 1st traction member 10 and the 2nd traction member 20 are formed double, compared with the case of a single layer, a big pulling force (traction force) can be exhibited. Accordingly, a large correction force opposite to the winding direction can be applied to the thick nail N and the hard nail N.
(2) The first locking portion 11 and the second locking portion 21 are formed in a double manner, and compared with the single case, the left end edge Na and the right end edge Nb of the nail N are applied in a wider range. Therefore, it is possible to prevent the traction force from being concentrated locally and to act on a wide range. Thereby, it is possible to prevent the thin nail N from being unnecessarily deformed or the extremely thin nail N from being torn.
(3) Since the turn-back portions Wa are provided on the insertion portions 11a and 21a at the distal ends inserted between the claws N and the nail bed of the first locking portion 11 and the second locking portion 21, they are rounded. It is possible to reduce the risk that the insertion portion will damage the nail bed. Furthermore, since the first locking portion 11 and the second locking portion 21 are doubled and the strength can be increased as compared with the case of a single layer, the length of the insertion portions 11a and 21a at the tip is accordingly increased. L can be shortened. This also reduces the damage to the nail bed.
(4) One end W1 and the other end W2 of one wire-like member W forming the first pulling member 10 and the second pulling member 20, respectively, are the first hook portion 13 and the second hook. Since it is located in the front-end | tip 13a of the part 23 and 23a, the whole intensity | strength can be raised rather than the case where it is located in another site | part. In addition, the first pulling member 10 and the second pulling member 20 can be easily manufactured.
(5) When the first pulling member 10 and the second pulling member 20 are pulled by the annular member 30, the “∞” -shaped first spring portion 12 and the second spring portion 22 are along the surface of the claw N. Since the contact is made (following), the postures of the first pulling member 10 and the second pulling member 20 are stabilized. Moreover, it is easy to generate a large traction force.
(6) Since the shapes of the first traction member 10 and the second traction member 20 are substantially the same and there is no right-and-left difference, both types can be used together. For this reason, manufacture and management become easy.
(7) A suitable traction force is generated according to the nail N to which the ingrown nail corrector 1 is attached, that is, according to the width of the nail N, the thickness of the nail N, the degree of the nail, etc. be able to.
(8) Since the first spring portion 12 and the second spring portion 22 are formed in a planar shape as a whole, they are formed by adjoining a single wire-like member W or a double wire-like member W. Compared with the case where it uses for a shape, the feeling of pressure with respect to nail | Nail at the time of mounting | wearing of the curly nail correction tool 1 can be reduced.

  4A to 4C are top views for explaining other shapes (modifications) of the first spring portion 12 (second spring portion 22).

  In the above-described embodiment, the first spring portion 12 and the second spring portion 22 have been described with respect to the case where the first loop-shaped portions 12b and 12b and the second loop-shaped portions 22b and 22b are substantially rhombuses. As shown in (A), two circles, a combination of rhombus and circle as shown in (B), a combination of triangle and rhombus as shown in (C), etc. may be used.

  5A and 5B are bottom views for explaining other shapes (modifications) of the first locking portion 11 and the second locking portion 21. FIG.

  In the above-described embodiment, the first locking portion 11 and the second locking portion 21 are configured such that the double (two) wire-like members W are in contact with or close to each other. The gap G may be opened. In this case, when the first locking portion 11 and the second locking portion 21 are locked (hooked) to the left end edge Na and the right end edge Nb of the nail N, the force acting on the left end edge is It acts by being dispersed over a long distance (portion) in the front-rear direction of Na and the right edge Nb. Thereby, a wound nail can be corrected even more satisfactorily.

  FIG. 6 is a side view illustrating another shape (modification) of the first hook portion 13 and the second hook portion 23.

  As shown in the figure, extension portions 13b and 23b are provided at the tips of the first hook portion 13 and the second hook portion 23 so as to be folded further inwardly. Thereby, when attaching the ingrown nail corrector 1 to the nail, the tip is sharp when pressed in the arrow direction with a finger from above so that the first hook portion 13 and the second hook portion 23 do not fall off the annular member 30. It is possible to effectively prevent the portion from hitting the finger.

  FIG. 7 is a side view illustrating another shape (modified example) of the first pulling member 10 (second pulling member 20).

  In the above-described embodiment, the case where the first spring portion 12 and the first spring portion 12 and the second spring portion 22 of the second pulling member 20 are formed in a substantially planar shape has been described. As shown in FIG. 7, the first intersection 12a and the second intersection 22a may be bent so that the first intersection 12a and the second intersection 22a are positioned above. In this case, since the bent portion is extended when the curl nail corrector 1 is mounted, this reaction force is generated and a more effective tensile force can be generated.

  In the above embodiment, although the case where the 1st traction member 10 and the 2nd traction member 20 were symmetrical with respect to the reference line C (refer FIG. 2 (A), (C)) was demonstrated, it is not necessarily limited to this. It is not necessary to be symmetrical with respect to the reference line C.

Moreover, although the above embodiment demonstrated the case where the 1st traction member 10 and the 2nd traction member 20 were the same shape, it is not limited to this, The ingrown nail correction tool 1 is different in shape. The first pulling member 10 and the second pulling member 20 may be configured in combination.
<Embodiment 2>

  With reference to FIG. 8, FIG. 9, the curl nail corrector 2 which concerns on Embodiment 2 to which this invention is applied is demonstrated. Here, FIG. 8 is a perspective view for explaining the ingrown nail correction tool 2 of the second embodiment. FIG. 9A is a top view for explaining the annular member 30A of the second embodiment, and FIG. 9B is a side view of the same.

  As shown in FIG. 9, the annular member 30 </ b> A as the connecting member has an annular portion 31 and a binding portion 32. The annular member 30A is formed, for example, by forming a closed loop annular portion 31 at an intermediate portion W3 of one wire-like member W and winding one end portion W4 and the other end portion W5 to each other. 32 is formed.

  The annular portion 31 of the annular member 30A is disposed in the vicinity of the center of the claw N in the left-right direction, and the first hook portion 13 of the first traction member 10 and the second hook portion 23 of the second traction member 20 described above are provided. Is engaged.

  The curled nail corrector 2 using the annular member 30A having the above-described configuration is attached to the nail N as follows.

  In FIG. 8, the state before mounting | wearing of the ingrown nail correction tool 2 is shown.

  The ingrown nail corrector 2 includes the first traction member 10, the second traction member 20, and one wire-like member W that forms the annular member 30 </ b> A after being mounted.

  As shown in FIG. 8, the wire-shaped member W is formed in a substantially “U” shape.

  First, the first locking portion 11 of the first pulling member 10 is hooked on the left end edge Na of the claw N, and the first spring portion 12 is oriented so that the two first loop-shaped portions 12b and 12b are aligned in the left-right direction. Place on the surface of the nail N. Thus, the first hook portion 13 is positioned on the left side of the claw N in the left-right direction.

  The same applies to the second pulling member 20. That is, the second engaging portion 21 of the second pulling member 20 is hooked on the right end edge Nb of the claw N, and the second spring portion 22 is oriented so that the two second loop-shaped portions 22b and 22b are aligned in the left-right direction. Place on the surface of the nail N. Thereby, the 2nd hook part 23 is located in the right side rather than the center of the left-right direction of the nail | claw N. FIG.

Next, the “U” -shaped wire-like member W is engaged with the first locking portion 11 of the first pulling member 10 and the second locking portion 21 of the second pulling member 20 as shown in FIG. 8. Let
One end portion W4 and the other end portion W5 of the wire-like member W are entangled and twisted lightly so as not to come off to make a small binding portion 32.

  Next, in order to prevent the wire-like member W from coming off from the first locking part 11 and the second locking part 21, lightly press it from above with the fingers of one hand and use a punch or nipper held in the other hand. Further, twisting is performed with the binding portion 32 interposed therebetween. Thereby, the binding part 32 is lengthened gradually, and the annular part 31 is made small. At this time, by appropriately adjusting the length of the binding portion 32, the size of the annular portion 31 is changed, and the force for pulling the first locking portion 11 and the second locking portion 21 is adjusted. As a result, the amount of extension in the left-right direction of the first spring portion 12 and the second spring portion 22 changes, and the pulling force (traction force), that is, the left end Na and the right end Nb of the claw N are pulled substantially obliquely upward. The power can be adjusted. That is, it is possible to apply a force in the direction of correcting the portion curved downward of the left edge Na and the right edge Nb of the nail N.

  Thereafter, an excess portion of the binding portion 32 of the annular member 30A is cut out, and an adhesive portion is applied to the whole to complete the mounting.

  According to the present embodiment, the annular member 30A can be formed by a single wire-like member W, not by a special one, and thus the configuration of the curly nail corrector 2 can be simplified. Can do.
