Description

The invention relates to medicine, namely to devices for correcting ingrown and deformed nails [A61F 5/11].

A DEVICE FOR CORRECTING INGRONG NAILS is known from the prior art [CN 217091070, publ. 02.08.2022], characterized in that it contains a first corrective part attached to the upper surface of the nail, a second corrective part attached to both sides of the front end of the nail, and a first corrective part; a positioning connector configured to adjust the length of the connecting member is located between two adjustment parts, wherein the first adjustment part includes a connecting rod, two locking plates respectively fixed on both ends of the connecting rod, and a connecting post vertically connected to the fixing plate, the second orthopedic part includes an omega-shaped force application element and a first nail hook and a second nail hook respectively secured to both ends of the force application element; The positioning connector is removably connected to the connecting rod and the force application element.

Also known is a CORRECTIVE SYSTEM FOR INGROWN/DEFORMED NAILS [https://foothelp.ru/services/ustanovka-korrektiruyushchikh-sistem-dlya-ispravleniya-formy-nogtevoy-plastiny/, web archive dated 01/25/2022], including stainless wire, which the specialist twists manually according to the deformed shape of the problem nail at the moment; the wire follows every curve of the nail plate with an omega in the center, the side walls of the nail are held in place by special hooks; The pressure exerted on the nail by the elements of the corrective system is evenly distributed over the entire surface, as a result the nail gradually unfolds into the correct anatomical shape, while maintaining the ability to work and the usual way of life, the absence of unpleasant physical sensations and aesthetic discomfort.

A common disadvantage of the above analogues is the use of a double-sided hook as a second corrective element, which is fixed under the surface of the nail, which does not allow the use of the claimed corrective systems in patients with anatomical features of the nail, in which it is difficult to tuck the arms of the hook under the sides of the nail.

A MEANS FOR CORRECTING INGRONG NAILS is also known [CN 102316831, publ. 01/11/2012], which in one embodiment includes a central part and an adhesive part made of linear elastic material; the connecting part is made of thermoplastic plastic and glued to the nail body, directly or through glue; the adhesive part fixes the end part of the linear elastic material constituting the central part; the shape of the connecting part can be easily adjusted; When gluing the adhesive part to the body of the nail, if the adhesive part is in a state of softening, a stronger connection can be realized; easier peeling can also be achieved. The disadvantage of the analogue is the inability to adjust the tension of the central part of the device, which reduces the efficiency of its use. The closest in technical essence is a KIT FOR NAIL CORRECTION [RU 2764999, publ. 01/24/2022], containing a primer (primer) containing hydroxyethylene methacrylate in an amount from 40 to 59.9%, phosphate dimethacrylate in an amount from 40 to 60%, an initiator in an amount from 0.1 to 1.0%; at least one composition for the formation of a photocurable corrective staple containing bisphenol A (di)methacrylate and urethane dimethacrylate in a ratio of 1:5 to 5:1 in an amount of 15 to 45%, fillers and pigments in an amount of 84.9 to 55% , camphorquinone, amine initiator in an amount of 0.1 to 1%. The method of using the claimed set involves the use, if necessary, of one or more metal elastic staples, wherein first a drop of photocurable material is applied pointwise to the nail and an elastic staple is pressed into this drop; after photocuring of the drop, the elastic staple is pulled over the nail and secured with a second drop of photopolymerizable material, each of both ends of the metal elastic bracket must protrude outward from the corresponding drop and must be visible outside it. Thanks to the appropriate method of installing metal elastic staples, mechanical irritation of the nail tissue is eliminated. The main technical problem of the prototype is the inability to quickly adjust the tension of the staple to correct treatment, since the staple is elastic, and one or more U-shaped bends made on the staple will return to their original position when trying to tighten when implementing the method of using the present invention. This drawback clearly reduces the effectiveness of the claimed set for nail correction.

The objective of the invention is to eliminate the shortcomings of the prototype.

The technical result of the invention is to increase the efficiency of correction of ingrown and deformed nails.

The specified technical result is achieved due to the fact that the method of nail correction, characterized by the fact that a piece of wire made of an elastic material is placed in the recess of the block, the wire is fixed along the edges of the block with the formation of at least two loops, a liquid polymer is applied to the places of the formed loops, forming After the fastening elements harden, adjust the fastening elements until a smooth surface is achieved, remove a piece of wire from the block, cut off the outer ends of the wire, additionally adjust the fastening elements, place the wire with fastening elements on the nail, fix the fastening elements on the sides of the nail with an adhesive connection, and then from the protruding Use your fingernail to form a loop on the free section of the wire, tighten and twist it, cut off the eye of the loop, apply a drop of liquid polymer to the cut site and leave until it hardens. In particular, the wire is made of nichrome.

In particular, the wire is fixed at the edges of the block using longitudinal rods.

In particular, the wire is fixed at the edges of the block using movable transverse rods.

In particular, acrylic is used as a liquid polymer. Brief description of the drawings.

Implementation of the invention.

An ingrown toenail is a fairly common problem that can be solved quickly and painlessly with modern techniques and the use of professional tools.

Currently, there are two types of corrective systems for the treatment of ingrown and deformed nails: hook and glue.

When using the hook system, the arms of the hook are tucked under the sides of the nail, a wire loop formed in advance is tightened and stretched in the direction from the center of the nail to the sides.

When using an adhesive system, the straightening mechanism is based on the internal tension of a pre-bent wire or plate, which is fixed to the nail by gluing in at least two places (at the ends of a piece of wire/thread) using acrylic, with the tension directed upward.

The disadvantage of the hook system is that its use does not always allow placing the hook under the nail, in particular with anatomical features (volumetric ridges) or with certain diseases, for example, patients with diabetes may not feel excessive harmful pressure and receive microtraumas when wearing the corrective system.

The disadvantage of the adhesive system is the inability to adjust the tension after installation and fastening of the system elements to the nail, which can only be solved by repeated reinstallation of wires (threads) with a different geometry or strength characteristics at certain intervals. In the case of “chubby” fingers, the adhesive system does not adhere to the nail due to the large radius of curvature of the nail in profile.

To eliminate these disadvantages, a method is proposed that allows combining the advantages of the two indicated correction systems. The method involves securing a wire (thread) to the nail using glue while maintaining the ability to adjust the tension of the wire (thread) by tightening the loop.

To implement the proposed method, a piece of nichrome wire 1, having the length required in the case of a particular patient, is placed in recess 2 of the block 3 and the wire 1 is fixed along the edges of the block 3, for example, on the longitudinal rods 4 (see Fig. 1), while forming loops 5, for example using movable transverse rods 6 (see Fig. 2).

The transverse rods 6 are removed inside the block 3, forming recesses into which acrylic is poured to form fastening elements 7 when solidified (see Fig. 3), which are adjusted until a smooth surface is achieved, for example, polished using a cutter (see Fig. 4).

Next, the pieces of wire 1 are removed from the block 3, the outer ends of the wire are cut off (see Fig. 5), after which the fastening elements 7 are additionally polished, and thus a correction system is obtained in the form of a piece of wire 1 with fastening elements 7, ready for installation on the nail patient (see Fig. 6). The mentioned corrective system is placed on the nail and the fastening elements 7 are fixed on the sides of the nail with an adhesive connection (see Fig. 7), a loop is formed from the free section of wire 1 protruding above the nail, tightened according to the patient’s sensations and twisted, the eye of the loop is cut off, a drop of acrylic is applied to the cut site and held until hardening (see Fig. 7).

A variant of a corrective system installed on the nail is shown in Fig. 8. In various embodiments, the correction system consists of one or more pieces of wire 1, each of which is equipped with at least two fastening elements 7.

The claimed technical result - increasing the efficiency of correction of ingrown and deformed nails - is achieved by combining the advantages of the above-mentioned hook and adhesive methods of nail correction: the corrective system is fixed on the nail by means of an adhesive connection while maintaining the ability to adjust the tension of the wire 1 by tightening the loop, while using fastening elements 7 provides stretching of the nail in a vertical plane in the upward direction, and an adjustable loop formed on wire 1 ensures stretching of the edges of the nail in a horizontal plane in the direction required by the patient. The use of nichrome wire in one embodiment is justified by the fact that nichrome has a better ability to be fixed in a given position compared to, for example, nitinol, which is widely used in the creation of corrective systems for nails. This property of nichrome allows the wire with a twisted loop to be fixed in a taut state, which increases the effectiveness of treatment.

The use of acrylic as a liquid polymer in one embodiment is justified by the fact that acrylic hardens in air, while other liquid polymers, including those used in some embodiments of analogues and the prototype, require photo-curing, which, subject to the absence or failure of the corresponding the necessary equipment can lead to a weak connection of the glue-gel with the fastening element and poor-quality fixation of the wire to the nail, which means it can lead to a decrease in the effectiveness of the correction.

An example of achieving a technical result.

In 2021-2022 The author of the invention produced samples of corrective systems in accordance with the description of the proposed method. We used wire made of nichrome, fastening elements were made of acrylic.

The manufactured elements of the corrective system were tested in practice during the work of beauty salons and in private clinics in comparison with the methods proposed in the devices implemented in analogues and the prototype. Since the effectiveness of nail correction under similar external factors depends, among other things, on the patient’s age, tests of the correction system manufactured by the proposed method were carried out on patients of various age groups (19 - 65 years, in 5-year increments).

Depending on the age group, tests have confirmed an increase in the effectiveness of the proposed method and correction system compared to analogues and the prototype, in particular, a 14-20% reduction in the time of nail correction for patients with comparable anatomy of the nail apparatus was noted, but it was not revealed how separation of fastening elements from the nail, as well as damage to the skin surrounding the nail, and the possibility of the most effective use of the proposed corrective system was confirmed in relation to all variants of the condition of the nail and nail bed selected for testing.

Examples of achieving a technical result are illustrated in Fig. 9 and 10.

In FIG. 9a shows the state of the nail before installation of the corrective system; Fig. 9b - 5 minutes after its installation.

In FIG. 10a shows the state of the injured nail before installation of the corrective system; FIG. 10b - nail with installed correction system, Fig. 10c - the result of its work after 20 days of wearing by the patient.
