Description

BACKGROUND OF THE INVENTION Field of the Invention [0001] The present invention relates to a suture for skin lifting or volume expansion of tissue,

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.

KR 10-1256908 B1

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.
