Description

  The present invention relates to an ingrown nail correction tool which is used for correcting ingrown nails, which is inexpensive, has a simple structure and is easy to manufacture, and which can be easily attached and removed by a person with ingrown nails.

  A state in which the outer edge of the nail plate is bent inwardly is called a wound nail or a bent nail, which is common in the heel (toe). Often, the nail horn at the tip of the bend bites into the flesh of the toes, causing pain and inflammation, and if left untreated, a nail can be formed on the side nail skin by irritation of the nail. Such a state is often called an ingrown nail, but an ingrown nail does not necessarily occur due to a wound nail, but the nail bed is damaged by a deep nail when the nail is cut or the nail corner is cut. The formation of nail spines due to leftovers is the cause of the occurrence, and in addition to this, excessive movement and inappropriate wearing of shoes cause pressure on the toes to compress the nails, further promoting the occurrence of ingrown nails and worsening the symptoms. Let

  Traditionally, surgical treatment of ingrown nails and ingrown nails is basically a nail mother, which is a place where the nail plate of the incised part that causes pain and inflammation is removed and the nail is made at the base of the nail Resection or chemical ablation of nails with phenol is common, but this involves anxiety and fear of surgery and pain during local anesthetic injections. In addition, pain and disinfection after surgery, and troublesome gauze replacement. In addition, post-operative nails are narrower and look worse and often recur.

Conventionally, various correction tools have been proposed to correct deformed nails such as wound nails and ingrown nails. For example, Non-Patent Document 1 and Patent Documents 1, 2, and 3 disclose orthodontic tools using superelastic alloys and shape memory alloys that are attached to the nail plate surface with an adhesive.

  Traditionally, treatment of ingrown nails and ingrown nails with ingrown nails has been done by removing the ingrown nail plate that causes pain and inflammation, and chemical cauterization or resection with phenol in the nail mother, where the nail is made However, this operation is relatively complicated, and the post-operative nail is narrow and unpleasant, often recurring and painful. not high.

  The correction tool in Non-Patent Document 1 and Patent Document 1 uses a shape memory alloy plate and is used in practice. However, it is not easy to securely bond the plate to the nail plate surface, and it is easy to peel off. The curled nail is corrected with a restoring force that is heated with a hair dryer and bent at a temperature of 45 ° C. or more, but the correcting force is weak. If the temperature drops, the correcting force disappears. That is, even if a plate is attached, a continuous correction force cannot be obtained. The price of the plate is also expensive.

  In the correction tool of Patent Document 2, a straightening or plate-like superelastic metal or shape memory metal correcting action body is arranged and fixed on the surface of a support made to a size suitable for the size of the nail plate, or It is buried inside the support, and the entire support is bonded to the nail plate surface with an adhesive, so that the deformed nail plate exhibits a corrective force gently. Depending on the size of each nail plate and the degree of curvature, the size of the support body, the number of corrective bodies attached to the support body, position, spacing, etc. will be adjusted and each individual will be made to order. Mass production is not possible. In addition, the production process is complicated and expensive. Furthermore, since it adheres widely to the nail plate surface, it is difficult to remove it once it is adhered.

  The correction tool disclosed in Patent Document 3 restores an elastic body by bridging an elastic body made of a linear or plate-shaped shape memory alloy between three or two points on the nail plate surface. The deformed nail is corrected with force. Although the structure is relatively simple and the correction force can be adjusted by increasing or decreasing the number of elastic bodies passed between the supports depending on the degree of deformation of the nails, the adhesive surface of each support to the nails is small, and the supports are It is inferred that it protrudes from the nail and easily falls off when caught by footwear or socks.

  The above-mentioned correction tools of Non-Patent Document 1 and Patent Documents 1, 2 and 3 are common in that a shape memory alloy or a super elastic alloy is used for the correction body and is fixed to the nail plate surface with an adhesive. . A common drawback is that the material is expensive and cannot be freely detached and abruptly dropped because it is secured to the nail using an adhesive. Also, it seems that it is quite difficult to properly attach the corrector using an adhesive to the surface of the nail plate that is strongly deformed and bent, and it is not possible to perform the treatment on its own.

  This method of correcting the deformed nail by the restoring force of the wire by passing the straight superelastic wire disclosed in Non-Patent Documents 2 and 3 through two small holes opened at the free edge of the tip of the nail plate Is a simple and excellent method that is currently spreading in practice. The superelastic wire to be used does not require any processing, and can be treated not only in a medical institution but also in a general surgical institution. The disadvantage is that the wire is expensive and that the nails need to be stretched to such an extent that a small hole can be drilled through the wire. In addition, if the position of the small hole through which the wire passes is inappropriate, the outer edge of the nail biting into the meat of the toes may not be sufficiently opened.

  The correction tools of Patent Documents 4 and 5 have a claw or a clamping portion at one end of a plate-shaped correction plate using a shape memory alloy or an elastic material, so that the correction plate is attached to the free edge of the tip of the nail plate. Although it is fixed to the back or front surface, the nail must be sufficiently stretched to fit the corrector firmly into the nail, and even if some adhesive is used for fixing, there is a possibility that it will fall off unexpectedly is there. In addition, a corrective plate of a size that fits the nail width and curvature to some extent is required, and it is necessary to make it according to each nail. It is difficult to use when the curl of the nail is strong, or when the corner of the nail bites into the meat and causes pain and inflammation. The materials are expensive and the manufacturing process is complicated.

Patent Documents 6, 7, 8, 9, 10, 11 and Non-Patent Document 4 are based on the principle of the nail plate by hooking locking portions or terminals, hooks, folded ends, etc. on both outer ends of the nail plate. By applying a pulling force in the opposite direction to the direction of deformation of the nail on the surface of the engaging part or the like, the nail curvature is corrected. Among these, the correction tools of Patent Document 9 and Non-Patent Document 4 are similar, and a pair of correction bodies including a locking portion formed of a wire having elasticity such as spring steel or steel steel is connected to the outer ends on both sides of the nail. After being locked to the nail, the bent nail surface is corrected by raising the outer edge of the nail by narrowing both correction bodies with a wire. In particular, the orthodontic appliance in Non-Patent Document 4 is an orthodontic appliance developed in Germany called VHO treatment, which is used for conservative treatment. Only licensees who have completed practical training are allowed to use and operate orthodontic appliances. It is not marketed for the general public and cannot be enforced by each person.

  Therefore, the main object of the present invention is to provide an ingrown nail correction tool that is inexpensive, has a simple structure, is easy to manufacture, can be operated by a person with an ingrown nail, and can be easily attached and detached, regardless of surgical operation. It is to be.

  In order to solve this problem, the ingrown nail correction tool of the present invention uses an inexpensive spring wire as a material, cuts it into a substantially semicircular arc shape, and forms both ends thereof in the outer direction of the arc. It is characterized by a simple structure that is bent into a hook shape and used as a locking portion to a nail.

  To attach to the nail, the arc of the orthodontic tool is squeezed and deformed and compressed into an approximately Ω (omega) shape. Insert the locking parts on both sides from the back side of the nail into the small hole and lock it to the nail, rotate the correction tool to the ventral side of the footpad and fix it with tape etc. using the locking part as a fulcrum . Opening with an ultrafine drill is performed manually from the back side of the nail, and each person may perform the opening himself or may be carried out by a third party. If you try to open a hole from the front side of the nail using an injection needle instead of an ultra-fine drill, it is better to stop it as you puncture the meat behind the nail as soon as you open the nail and see the painful eyes.

When this orthodontic tool is attached, the orthodontic appliance deformed and compressed into an approximately Ω-type and attached to the wound nail is wound according to the restoring force of the spring wire rod that attempts to return to the original substantially semicircular arc shape. The bent outer edge of the nail is slightly opened immediately, and the wound nail is gradually corrected if the corrector is continuously worn.

  When the outer edge of the wound nail is bent around 90 degrees, it is certain that the nail can be locked by inserting the locking part of the corrector into a small hole opened with an ultra fine drill. Even if you do not make a small hole in the claw, if the length of the locking part is appropriate, the locking part can be caught on the back side of the nail and it can be locked well by the restoring force of the spring wire. Good.

  The curly nail correction tool of the present invention uses an inexpensive spring wire as a raw material, but a shape memory alloy or a super elastic wire may be used if the price is not particular.

  Since the orthodontic appliance has a simple structure and is easy to manufacture, and the material is inexpensive, it is easy to provide the product as a product at a low price. In addition, due to the shape of this orthodontic appliance, it can be used in a wide range of sizes with a single orthodontic appliance without being greatly restricted by the size of each nail, the degree of wound nails, the extent of nail extension, the size of the toes, etc. Therefore, for example, almost all wound claws can be handled if S, M, and L size correction tools are prepared. The magnitude of the correction force depends on the diameter and hardness of the spring wire, but it can be adjusted to some extent by the degree of opening of the arc mouth of the correction tool when worn.

  The straightening principle of expanding with the restoring force of the spring wire rod with the wound nail engaged with the nail is simple and clear and easy to understand. This seems to be a great motivation to use this orthodontic tool.

  The nail requires two openings, but this ensures that the orthotic is locked to the nail and does not use any adhesive to fix it. In other words, it can be easily worn by one's own intention, and can be taken when it is desired to take out the corrector when going out or taking a bath. It is recommended to use this orthodontic tool according to your lifestyle, such as wearing it at bedtime, removing it when you go out, walking, and wearing it when you work at the desk.

  Almost all conventional orthodontic appliances are attached to the nail plate surface, and there were cases where it was anxious that they could be seen from the outside. Because it is fixed with, it is hardly noticeable in appearance. However, since the correction tool is fixed to the ventral side of the toes, it takes some time to get used to the feeling of wearing the back of the finger when walking barefoot while wearing. When walking with shoes on, I don't care.

  If the horn of the claw digs into the flesh of the toes and hurts, or if the side nail skin is swollen for that reason, wearing this corrector immediately causes the curl of the claw nail to open slightly and Since the orthodontic appliance is rotated and fixed to the ventral side of the toes with the fulcrum as the fulcrum, the outer edge of the nail bent due to the lever principle will float slightly, so that the meat that has bite into the nail will also be separated from the nail Relieve pain and swelling in a relatively short time because

  It is desirable to use a spring wire rod made of stainless steel for the material of the orthodontic tool 1 so as not to corrode due to steaming of the feet. The diameter of the spring wire depends on the desired correction force, but 0.4 mm to 0.6 mm is appropriate with 0.5 mm as a standard.

As shown in the plan view of FIG. 1B, the spring wire is cut and bent into a substantially semicircular arc shape, and both end portions thereof are bent into a hook shape in the outer direction of the arc to be engaged with the claw. 2. The locking portion 2 is produced by bending both end portions of the spring wire material at a substantially right angle with respect to the arc surface, and then bending at a position approximately 2 mm from the bent portion and further at a substantially right angle in the outward direction of the arc.

  As shown in FIG. 2, the arcuate mouth of the orthodontic tool 1 is squeezed and deformed and compressed into a substantially Ω (omega) shape as shown in FIG. The locking part 2 is inserted into the small hole opened from the back side of the wound claw 6 and locked. When the outer edge of the nail is strongly bent at the time of locking to the nail, it is easier to lock the nail by providing a gentle bent portion 3 at the end of the arc portion of the correction tool 1 so as to bend outward.

  FIG. 3 shows a state in which the corrector 1 is mounted on the wound nail 6 of the heel 7. A spring wire having a diameter of 0.5 mm to 0.6 mm is used for the correction tool 1 used for correcting the wound nail 6 of the heel 7, and this is cut into a length of 6 to 7 cm. It is sufficient that the tip of the locking portion 2 has a length of about 2 mm, but the length is determined by the degree of bending of the outer edge of the wound nail 6 and the thickness of the nail plate, so keep it slightly longer. What is necessary is just to cut | disconnect the excess front-end | tip part which came out on the nail | claw back | upper surface after engaging with a nail | claw.

  Since the orthodontic appliance 1 is locked to the nail after being locked to the nail, it can be understood from the front view of FIG. 1 (a) and the side view of FIG. 3 (a) so as to become familiar with the contour of the toe. On the whole, gentle curves 4 and 5 are given.

  Since this orthodontic appliance has a simple structure and is easy to manufacture, it can be mass-produced industrially. In addition, since the material is inexpensive because it uses a spring wire, it is easy to provide the product as a product at a low price and has industrial applicability.
