Description
The present invention relates to a suture for lifting the skin or expanding the volume of skin tissue. The suture is inserted into the skin layer to lift the skin and form the skin tissue to induce adhesion between the skin layers to maintain the lifted state, , A suture which inflates the volume of skin tissue to improve elasticity and the like and to enhance the sense of volume.
As people get older, wrinkles appear on the surface of the face or body. The principle of wrinkling is that the muscles contract, and the skin and fat layers are struck by gravity. The wrinkles are made perpendicular to the contraction direction of the muscles and become deeper with age.
The method of removing wrinkles can be broadly divided into chemical methods and physical methods.
One of the chemical methods is to paralyze muscles that cause wrinkles with Botox, but it has an unnatural facial expression and it is difficult to use under eyes, lower lip, wrinkles, etc., and there are limitations on thick and deep wrinkles There is a problem that the effect is only 3-6 months.
As a physical method, there is a method of using a filler to pull out the inserted part. The liquid filler is convenient to inject, but when the muscle is injected into the skin, the muscle moves in the direction of contracting, It brings the phenomenon to be seen in the inside and it is disassembled and absorbed after a certain period (about 1-2 years).
In another physical method, there is a method of inserting a very thin gold thread into the subcutaneous layer. The gold thread causes a foreign body reaction to produce a new tissue around the gold thread. However, the gold thread is limited to use in thick wrinkles. There is a risk of bending or protruding out of the skin, and it may be permanently left intact to cause interference in X-ray, CT, MRI, and the like, which may lead to problems in diagnosis.
As another physical method, there is a facial elevation method in which the skin is pulled and pulled to remove the part of the skin. However, this method is likely to recur gradually over time, and the power transmitted to each part The wrinkle removal may not be uniformly performed. In addition, the effect is greatest when the skin is very stretched and the wrinkles are severe, and when the skin is thin, the operation method is not effective.
Accordingly, the present invention overcomes the above-mentioned problems, and can be applied not only to the case where the wrinkles are very severe but also to the adults of the twenties to forties, and to provide a suture that can be performed even when the skin is thin.
The object of the present invention is to provide a suture which is inserted into the skin to lift the skin to improve or eliminate the wrinkles of the skin.
Also, the object of the present invention is to induce a new tissue to be formed in the skin through one or more through holes that allow skin tissue formation and skin layer adhesion to occur after being inserted into the skin, so that even if the suture itself is decomposed and absorbed, To provide a skin lifting suture that allows the lifting effect to improve or eliminate wrinkles to be (semi) permanently sustained.
Another object of the present invention is to provide a skin-lifting suture which induces the volume of the skin tissue to be expanded by inducing a new tissue to be inserted into the skin.
In order to solve the above-mentioned problems, the present specification discloses a medical device comprising at least one through-hole for lifting the skin to improve or remove wrinkles of the skin and to allow surrounding tissue cells to grow up to allow tissue formation and inter- A suture having the shape of a sheet is provided.
The present disclosure also provides a kit comprising a suture that lifts the skin.
The suture of the present invention can be inserted into the skin layer to lift the skin and physically remove the wrinkles formed on the skin. The peripheral tissue cells of the inserted suture grow into the suture, inducing the formation of a new tissue in the skin, And the effect of removing the wrinkles is (half) permanently sustained.
In addition, the suture of the present invention can prevent a phenomenon in which a new skin tissue is firmly formed and a suture is stuck, and a phenomenon that a wrinkle is struck again by gravity and recurred.
The suture of the present disclosure may also include one or more protrusions located at each corner of the upper, lower, or cross-section in the longitudinal direction, wherein the protrusions are positioned such that the upper protrusions . Therefore, unlike conventional sutures, the suture of the present invention can securely transfer the force to each skin layer to more surely lift the skin, and the lifting or wrinkle removing effect of the force-applied skin is prolonged for a long time.
Such skin lifting and the formation of a new skin tissue cause the skin epidermis, dermis and subcutaneous fat layer struck by gravity to have a resilience similar to that of the underlying skin muscle, thereby improving or eliminating the wrinkles of the skin.
In addition, the suture of the present specification can be used to effectively improve or remove wrinkles by lifting the skin in accordance with a three-dimensional contour of the face, and is applicable to an adult of very low wrinkles or a person whose skin is very thin and wrinkles occur relatively early Thereby exhibiting the effect of continuously improving or eliminating wrinkles.
In addition, the suture in the present specification has the effect of expanding the volume of the skin tissue by inducing the formation of new tissue cells to improve or eliminate wrinkles.

In the present specification, the term " decalcomania structure " means that one or more protrusions are arranged in a direction facing each other with respect to the center of the decalcomania structure, or in a direction in which they are oriented in the same direction. In one aspect of the present invention, the projections may have one or more of these decalcomania structures.
In one aspect of the present invention, the projections may be those located on one side of the sheet and those located on the opposite side of the sheet in the same direction.
In one aspect of the present invention, the protrusion may have a pointed shape, a hook shape, a curved shape, a deformed polygonal shape, or a polygonal shape. In the case of the hook shape, the end may be curved.
In one aspect of the present invention, the projections may be located on one surface of the sheet and those located on the opposite surface of the sheet may be the same or opposite to each other. In the case where the direction of the projection is opposite to that of the opposite direction, the projection may be located on either side of the width of the sheet or on the lower surface of the width, or on one or more edges of the sheet Lt; / RTI > When the protrusion is located on the lower side of the width, any protrusion may be fixed to the skin layer on the basis of the skin incision surface, and the protrusion on the other opposite surface may be fixed to the skin layer below the incision surface. For example, one of the protuberances is fixed to the subcutaneous fat layer of the skin, lifting the skin to wrinkle, and the opposite protrusions can be fixed on the fascia after pulling the skin to prevent the skin from being stuck again.
In the present specification, the term "clasp" is different from the protrusion. In the case of the protrusion, there is at least one side or edge of the width of the suture to fix the skin, or the clasp is located at the end of the longitudinal direction. It means big.
In one aspect of the present invention, the latch included in the suture may be formed by a method of integrating the latch by a frame, or a method of separately forming a latch and joining to a suture, but the present invention is not limited thereto.
In one aspect of the invention, the suture may comprise one or more latches at the longitudinal end. Further, in one aspect of the present invention, the latch may be located at the same position where the projection is located.
In one aspect of the invention, the latch may be inserted into the skin to lift the skin layer.
As used herein, the term "growth factor" includes platelet-derived growth factor (PDGF), angiogenesis factor (AGF), fibroblast growth factor (FGF), transforming growth factor- ), Epidermal growth factor (EGF), connective tissue growth factor (CTGF), vascular endothelial growth factor (VEGF), and the like.
In one aspect of the present invention, the suture may comprise a growth factor on or in the sheet.
In one aspect of the present invention, the suture may be made in part or all of a biodegradable polymer, a non-biodegradable polymer, or a combination thereof.
In one aspect of the present invention, the suture includes a polyglycolic acid (PGA), a hyaluronic acid (HA), a polylactic acid (PLA), a polyglyco-lactic acid But is not limited to, one or more biodegradable polymers selected from the group consisting of polydioxanone (PGLA) and polydioxanone (PDS).
In one aspect of the invention, the suture may be made of, but not limited to, one or more non-biodegradable polymers selected from the group consisting of polyethylene, polypropylene, polypropylene ethylene, nylon, silicone and Teflon.
In the case of a suture according to one aspect of the present invention, the suture can be inserted into the skin layer by a method commonly used in the art.
In one aspect of the invention, the suture may be made in one piece.
In one aspect, the present invention relates to a kit comprising a suture and a needle according to one aspect of the present invention.
In one aspect of the invention, the kit may further comprise attachment means capable of attaching to the fascia.
In one aspect of the present invention, the attachment means can include a mesh, a gauze, or a plate, but is not limited thereto as long as it can be attached to the fascia to fix the suture.
In one aspect of the invention, the kit may further comprise instructions describing how to use the suture.
In one aspect of the present invention, the method of using the suture is as follows.
1. Insert a needle into the space between the subcutaneous fat layer and fascia of the incised skin.
2. Adjust the position of the inserted needle so that it can be positioned on the skin to be treated by inserting the suture, and adjust the direction and position of the needle with one hand with the other hand.
3. Position the needle at the skin site to be treated and insert the suture through the needle into the skin.
4. Adjust the inserted suture so that it is seated and remove the needle only from the skin when the tip of the suture is fixed to the skin.
5. Pull the suture inserted into the skin with your hand so that the wrinkles on the skin surface can be pulled.
6. When the suture is fixed in position, it is combined with the attachment means attached to the temporal muscle film to fix the suture so that it does not flow down over time.
7. Suture the skin incision surface.
Hereinafter, sutures according to one aspect of the present invention will be described in detail with reference to the accompanying drawings.
The matters shown in the drawings described below are for illustrating one embodiment of the suture in the present specification, and the scope of the present invention is not limited thereto.
