WO2012011842A1 - Method for implanting eyelashes (variants thereof) - Google Patents

Abstract

The invention relates to cosmetics, specifically to artificial eyelashes. The method comprises introducing eyelashes into the eyelid with the aid of a surgical needle leaving the root of the eyelashes inside the eyelid and drawing the bodies of the eyelashes outwards in the area of eyelash growth. In the first variant of the method, a cluster of at least two eyelashes having a common root is used. Each eyelash is introduced into one puncture which is common to all of the eyelashes, while each eyelash is led out individually at a distance of at least 0.1 mm with respect to one another, whereupon the root of the eyelashes is sunk into the eyelid via said puncture. In the second variant of the method, at least two eyelashes are introduced into one common puncture, while said eyelashes are led out individually at a distance of at least 0.1 mm with respect to one another, whereupon the eyelashes are joined at the entry point so as to form a common root, which is sunk into the eyelid, via said puncture.

Description

 The method of implantation of eyelashes (its options)

 Technical field

 The claimed invention relates to cosmetics, namely to artificial eyelashes.

 To increase the volume and length of the eyelashes, various mascaras are usually used. There are a huge number of mascara recipes and tools that extend the eyelashes, as well as designs of brushes for their application. When using mascara, the cosmetic effect depends on the initial state of the eyelashes, and especially on their thickness and frequency. With rare thin eyelashes, the use of mascara does not lead to a significant cosmetic effect.

 There is a category of people whose eyelashes are missing partially or completely due to burns, chemotherapy, injuries or various pathological processes. The complete or even partial absence of eyelashes creates cosmetic and sometimes moral discomfort, especially in young patients.

 State of the art

WO 02/085186, M.C. A61 B, 2002 describes a method for implanting artificial fibers into a strip having at least one layer similar to human skin, according to which a hole is made in a layer similar to human skin of a predetermined diameter, enter one end of the preform into the hole, strengthen it in the layer with a knot whose diameter is larger than the diameter of the hole, and leave the body of the eyelashes outside. After strengthening the desired number of eyelashes on the strip, it can be glued with a suitable adhesive on the upper or lower eyelid. In the absence of eyelashes only on a part of the eyelid, it is possible to form a segment corresponding to the length of this part. Standard workpieces according to WO 02/085186 have a length of 2.8 cm and a width of 4 mm, but other sizes are possible. The strip can be multilayer, but the upper layer, in which the eyelashes are strengthened, should resemble human skin in color and texture. Material for eyelashes should be similar to human hair. As glue, waterproof rubber latex can be used, which is applied in a thin layer to the back wall of the strip. The disadvantage of artificial eyelashes according to WO 02/085186, like any false eyelashes, is that they cannot be worn constantly. The glue used to fix them can cause an allergic reaction; the constant presence of a glued strip causes irritation of the thin skin of the eyelids.

A method for implanting the patient’s own hair as eyelashes is also described [www.volosy.ru, 04/14/08]. According to In this way, under local anesthesia, grafts (transplant material) of 1-3 follicles are cut from the scalp, for example the occipital one. Around the shaft of hair and follicle, the maximum possible amount of fiber is removed. Hair is inserted into a surgical needle. With the help of a needle, implantation is performed in the eyelid tissue in the eyelash growth zone: the hair is stretched under the skin until the follicle (eyelash root) is immersed in the eyelid tissue and the hair is brought out. Implantation requires the usual postoperative management of the patient. The operation is performed under local anesthesia.

The usual difficulties of transplanting hair into the eyelash region - thin skin, a small amount of subcutaneous tissue, complexity of the eyelid structure - are supplemented by possible complications such as postoperative pruritus, in which the patient risks losing the implanted eyelashes and causing infection, as well as the constant growth of transplanted eyelashes, and, in some cases, their curliness. Contraindications to the implantation of hair as eyelashes are also a tendency to form a keloid scar, anemia, impaired anatomy of the eyelids and a tendency to alopecia areata. All this limits the possibilities of this method. A method for implanting artificial eyelashes involves inserting eyelashes into the eyelid using a surgical needle and removing the eyelash body outward in the eyelash growth zone, while the eyelash root remains inside the eyelid [RU application 2007122568, 2008]. As a eyelash use a polymer thread. The known method allows the implantation of a bundle of (two, three or more) eyelashes, all of which are displayed in one place, simultaneously, through a common implantation channel for them. The eyelash root can be designed as a common node.

 This method has the significant drawback that, as experience has shown, implanted eyelashes can easily be pulled out or fall out themselves after a certain time, different for each patient.

 In addition, the eyelashes of the beam, located in the same implantation channel and communicating with the environment, form a kind of drainage, on the surface of which infection can penetrate into the eyelid tissue. Single implanted eyelashes lack this drawback, as they are densely surrounded by eyelid tissue throughout the entire circumference.

An analysis of the long-term results of implantations showed that the mechanism for fixing artificial eyelashes in the eyelid tissue needs in improvement. Moreover, it became obvious that the decisive role in counteracting the ejection (rejection reaction) of the eyelash is not played by the shape of its root part, but by mechanical resistance to the direction of the ejection force.

 Disclosure of invention

 The basis of the invention is the task of preventing the loss of implanted eyelashes.

 This problem is solved by the fact that in the method of implanting eyelashes, including the introduction of eyelashes into the eyelid using a surgical needle to leave the root of the eyelashes inside the eyelid and removing the bodies of the eyelashes outward in the region of the anterior rib of the eyelid (in the zone of eyelash growth), use a bundle of at least of two eyelashes having a common root, and each eyelash is injected into one common puncture for them, and removed separately through the skin of the anterior rib of the eyelid, at a distance of at least 0.1 mm from each other, after which the eyelash root is immersed in the eyelid through the specified puncture (1 in Rianta).

This problem is also solved by the fact that in the method of implanting eyelashes, including the introduction of eyelashes into the eyelid with a surgical needle, leaving the root of the eyelashes inside the eyelid and removing the bodies of the eyelashes outward in the area of the front rib eyelids (in the zone of eyelash growth), at least two eyelashes are injected into one common puncture for them, and separately removed through the skin of the anterior rib of the eyelid at a distance of at least 0.1 mm from each other, after which the eyelashes are in place input connect, forming a common root, which is immersed in the eyelid through the specified puncture (option 2).

 This problem is also solved by the fact that in the method of implanting eyelashes, including the introduction of eyelashes into the eyelid using a surgical needle to leave the root of the eyelashes inside the eyelid and removing the bodies of the eyelashes outward in the region of the anterior rib of the eyelid (in the zone of eyelash growth), at least two eyelashes are introduced individually through the skin of the anterior rib of the eyelid at a distance of at least 0.1 mm from each other, and output through one common puncture for them, after which the eyelashes at the exit site are connected, forming a common root, which is immersed in the eyelid through the specified proc ol (option 3).

As a material for artificial eyelashes, a polymer surgical thread of black, dark brown, dark blue, dark gray color with a diameter of 0.04-0.6 mm (USP 8 / 0-2) is used. It can be polypropylene, nylon (polyamide), polyvinylidene fluoride surgical sutures. Can use also cut sterilized human hair with a diameter of 0.05-0.09 mm.

 When forming the root part of the eyelash bundle, the threads can be knotted, glued or welded together.

 Special artificial eyelashes can be made, which are a bunch of two to four eyelashes that simulate natural eyelashes and have a common root. In this case, they are implanted by the method according to the first embodiment.

 Implantation is carried out using a curved surgical needle with a steepness of a bend of a circle and a trihedral sharpening of a cylindrical peak (tapercat). At the opposite end of the needle, an eye is made in the form of a metal or polymer loop.

 If you need to expand the puncture to enter the root of the eyelash, you can use a curved surgical needle with a larger diameter with a cutting end.

 The method is carried out in the following way.

 Manipulation is carried out under local anesthesia. The skin of the eyelids is treated with an antiseptic solution.

A surgical needle with an eye is inserted at a distance of 3-4 mm from the free edge of the eyelid, is passed through the tissues of the eyelid and brought out through the skin of the eyelid in the anterior margin of the eyelid (in the area of eyelash growth). In FIG. 1 shows schematically the place of introduction of the needle (1) and the place of removal of the needle (2). Part of the abalone is not immersed in the thickness of the eyelid, leaving it outside at the puncture site. One of the eyelashes of the beam is placed in the eye, after which the eye with the body of the eyelash is completely removed from the eyelid tissue to the outside through the skin in the region of the anterior rib of the eyelid. The root with the remaining (remaining) eyelash (s) is left outside for now. Then the needle with the eye is inserted into the same puncture, and removed through the skin in the region of the anterior rib of the eyelid at a distance of at least 0.1 mm (0.2-0.9) from the first implanted eyelash. Part of the abalone is not immersed in the thickness of the eyelid, leaving it outside at the puncture site. The remaining eyelash of the beam is placed in the eye, after which the eye with the body of the eyelash is passed through the eyelid tissue and brought out. If there are 3-4 eyelashes in the beam, the manipulation is carried out one more time - two times.

 When all the eyelashes of the bundle are drawn through the eyelid tissue, all eyelashes are simultaneously grabbed with tweezers and pulled, completely immersing the root under the skin of the eyelid.

In the second variant of the method, individual eyelashes are injected at a distance of 3-4 mm from the free edge of the eyelid into one common puncture for them, and they are removed through the skin in the region of the anterior edge of the eyelid to a distance of 0.1-0.9 mm from each other. The ends remaining above the puncture connect (bind, solder) forming the root part of the eyelashes, which are immersed in the thickness of the eyelid, pulling all the removed eyelashes at the same time.

 For implantation of eyelashes using a surgical needle with an eye. You can also use a surgical needle with a polymer thread fixed in it.

 In FIG. 2-4 show the steps of the second implantation method.

The needle is pierced at a distance from the free edge of the eyelid, drawn through the tissue of the eyelid (Fig. 2), then the thread is pulled, the thread is cut off with a margin (Fig. 3).

 Then the needle is injected into the same place where it was inserted for the first time, and removed at a distance from the implanted eyelashes, then stretching the thread, which is cut off with a margin. The manipulation is repeated depending on the required number of eyelashes in the beam (Fig. 4, Fig. 5).

Threads passed through the eyelid tissue above the injection site are tied together and the knot (beam root) is immersed in the eyelid, pulling all the removed eyelashes at the same time (Fig. 6). Excess material is cut off from the root. A bunch of grab, pull and immerse its root part under the skin of the eyelid. Lashes are cut to the desired length (Fig.7).

 In the third variant of the method, individual eyelashes are introduced through the skin of the anterior rib of the eyelid at a distance of at least 0.1 mm from each other, and output at a distance of 3-4 mm from the free edge of the eyelid through one common puncture for them, after which the eyelashes are in place the output is connected, forming a common root, which is immersed in the eyelid through the specified puncture. In FIG. Figure 8 shows the area of needle sticking with this method of implantation. After the eyelashes are drawn through the eyelid, they form the root part and immerse it under the skin of the eyelid.

 There is no need to stitch a puncture. An antibacterial ointment and a narrow aseptic dressing are applied to the skin of the eyelids.

 The invention is further illustrated by examples, but not limited to.

 Example 1

Patient M., 43 years old, noted insufficient density of eyelashes in the lateral part of the upper eyelids. 2 bundles of artificial eyelashes were implanted in this patient, including 3 artificial eyelashes and to control 3 single eyelashes with the root part, made in the form of a double loop with a knot.

 As artificial eyelashes used surgical suture material polyvinylidene fluoride 6/0, painted in black. A day after implantation, small areas of subcutaneous hemorrhages and weak swelling of the skin of the upper eyelids in the area of intervention were visualized, which disappeared by the third day after the manipulation.

 In FIG. 9 is a photograph of the patient’s right eye 5 months after implantation. Both bundles of implanted artificial eyelashes (2,3) maintain their correct position. Of the implanted single eyelashes, two fell out, one (1) is in the area of implantation, however, its dislocation occurred, which indicates that it will soon be rejected by the eyelid tissue.

 6 months after implantation, the last single eyelash fell out.

 Throughout the entire period of observation of the patient (12 months), the implanted bundles of artificial eyelashes maintain their correct position, and the eyelid tissue in the implantation area remains without signs of inflammation.

Example 2 Patient Yu., 28 years old. She was implanted in the lateral part of the upper eyelids with one bundle of artificial eyelashes, including 3 eyelashes. As artificial eyelashes used surgical suture material polyvinylidene fluoride 6/0, painted in black.

 A day after implantation, a minor area of subcutaneous hemorrhage was visualized on the upper eyelid of the right eye in the area of intervention, weak swelling of the skin of the upper eyelids in the area of implantation, which disappeared by the third day after implantation.

 Throughout the entire period of observation of patient Yu. (9 months), the implanted bundles of artificial eyelashes maintain their correct position; inflammatory changes and signs of rejection of the implanted eyelashes are not observed from the side of the surrounding tissue.

 As the experience of implantation shows, the eyelashes of the beam from the common root, brought to different positions of the anterior rib of the eyelid, hold the entire beam at the implantation site and prevent its migration.

A feature of the implantation of an eyelash bundle, in which each eyelash of the bundle is tightly surrounded by a sufficient amount of tissue century, is a reliable prevention of infectious complications of this manipulation.

Industrial applicability

 The inventive method for implanting eyelashes can be used both in the practice of ophthalmologic clinics in the treatment of patients who have lost eyelashes due to illness due to burns or partial or complete alopecia, as well as in the work of beauty institutes when implanting to patients who are unsatisfied with the state of their eyelashes.
