JP2011098081A - Nail deformation correcting device by double fitting plate - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To provide a device to be used for the non-operative treatment of an ingrown toenail and onychocryptosis, which is hardly removed (1), is used even when a nail is not made to grow so much (2), continuously adds force to correct the nail (3), and is easily operated (4). <P>SOLUTION: Two elastic metal plates, each of which has a hook at one end, are mutually fitted and mounted on the nail, thereby to continuously add the force to the nail by repulsion force of the two metal plates. Thus, a power point, a fulcrum, and a working point work for the entire width of the nail, so that the curvature of the nail is corrected. <P>COPYRIGHT: (C)2011,JPO&INPIT

Description

  The present invention relates to nail deformation correction.

  Conventionally, there are three main methods for non-surgical treatment of wound nails and ingrown nails. Each method and its drawbacks are described below. The first method is to attach an elastic plate such as metal or plastic to the nail with an adhesive. This has a drawback that the elastic plate is easily peeled off from the nail. The second method is to pass an elastic wire through the nail. This method has a drawback that it cannot be used unless the nail extends from the tip of the finger. The third method is to fix the metal wires hooked to both ends of the nail and fix them at the center. In this method, only the traction is applied at the time of wearing, and the correction force is not sustained after the wearing. In addition, the technique is complicated, practical skill training is necessary and expensive. In the treatment of wound nails, it is desirable to maintain a continuous correction force for a period of approximately 1 to 2 months during which the nails extend.

Patent Document 1 proposes to pull the nail with a wire to correct the curvature of the nail.
However, in the invention of the above-mentioned patent document, the correction force of the nail works when the correction tool is attached, but the correction force does not work continuously thereafter. In addition, the operation at the time of wearing is complicated, and a practical training is required. In the present invention, the correction force is continuously applied to the nail, and the correction force can be appropriately selected from strong, medium and weak by changing the thickness of the metal plate. In addition, it is easy to install and does not require on-site training, and can be provided at low cost.

  In the present invention, two metal plates each having a hook at one end are fitted to each other, and the curvature of the nail is corrected by the repulsive force of the two metal plates. In this method, the repulsive forces of the two plates are combined with each other, and the force point, fulcrum, and action point are the full width of the nail. Since it is hook-fixed, it does not peel off at the adhesive surface unlike adhesive-fixed. In the case of fixing the hook, the hook is loosened and easily comes off, but in order to prevent this, the thread was applied to both plates and the crossbar, and a tension was applied so that the brace was close to the center. This thread also has the function of bringing the two plates into close contact so that they do not leave.

  The present invention has the following effects. For one, the conventional drawback of the orthodontic appliance coming off was eliminated. Secondly, unlike elastic wires, it can be used even if the nails are not extended. Third, the corrective power of the nails was maintained continuously. Fourth, by changing the thickness of the metal plate, it is possible to select an appropriate correction force of strong, medium and weak. Fifth, the technique is simple and does not require a workshop, so it can be provided at low cost.

It is the front view at the time of mounting | wearing to the nail | claw of this orthosis, and the one part enlarged view. FIG. 8 is a drawing-substituting photograph showing the attachment of the brace to the nail.

As shown in FIG. 1 to FIG. 4, this brace is a metal plate having a hook of an appropriate size for hooking a claw at one end. This metal plate has elasticity, and is made of a metal having such a property that a force to always return when the metal plate is moved along the nail continuously. The total length is basically 30 mm, but if necessary, stretching and shortening by about 10 mm is allowed. A cross bar is joined in the middle of the brace metal plate. The crossbar has a total length of about 2 mm and is a wire made of the same kind of metal as the plate. The diameter is basically 0.4 mm, but may be increased or decreased by about 20%. One end of the cross bar ends in a straight line, and the opposite side has a structure bent at 90 degrees. This 90 degree bend is not limited, and a change of about ± 5 degrees is allowed. The cross bar is welded at a right angle to the plate at a position 4 mm from the tip of the hook, and the bending direction of the cross bar is the same as the bending direction of the hook. The mounting position is not limited, and a change of about ± 1 mm does not greatly affect the effect. In carrying out the mounting, as shown in FIGS. 5 and 6, the hook 3 of this device is hooked on the edge of the nail A, and another device is similarly hooked on the edge of the nail on the opposite side. After two symmetrically hooked plates 1 of the orthosis are fitted under the crossbar 3 of the orthosis facing each other, the left and right 2 plates are moved at the crossbar portion with the thread 4 passed in advance. Tighten at the place, and further bond the left and right threads together at the center of the nail. By doing so, the hook can be fixed without peeling off from the nail. The correction force can be continuously applied to the nail by the repulsive force of the elastic metal plate.
