Description

Lifting seal with asymmetrical structure

The present invention relates to a medical thread, and more particularly, to a lifting thread having an asymmetric structure to maximize the effect of wrinkle improvement during the lifting procedure for removing wrinkles.

As interest in skin care is increasing day by day, various procedures for removing wrinkles have emerged.

In general, wrinkle removal refers to tightening or restoring the original shape when the skin is drooped or fat is accumulated and the skin of a specific area is changed.

The wrinkle removal procedure is divided into invasive surgery using a method such as removing a drooped tissue after large incision of the skin, and non-invasive surgery that minimizes the incision site and tightens it using an injection or a thread. Sometimes.

In the former case, the incision of the skin is necessary, the operation time is relatively long, and it takes a long time to recover.

Recently, the latter method has been widely used. Also called lifting method, instead of cutting the skin, a specially treated thread, such as cog, is combined, or about 0.5 mm in diameter made of synthetic fibers such as silicone or polypropylene. It is a surgical method that removes wrinkles and rejuvenates tension by pulling together the aged skin and the aged soft tissue (SMAS) in the skin by using the thread.

This method can be used to minimize scarring, which is the biggest disadvantage of using a scalpel by using a needle through simple local anesthesia, reducing irritation or damage at the site of surgery, as well as bleeding and resulting swelling. There is no choice but to reduce the natural tension after surgery to give the skin elastic and youthful effect, such as being used a lot.

Korean Utility Model Registration No. 20-0320005 discloses a medical thread in which spines are formed on the surface of a conventional thread.

However, in the case of using a small diameter thread made of synthetic fibers as described above, the phenomenon of sawing or eating phenomenon occurs when excessive tension is applied to the thread. There is this. In particular, the yarns disclosed in the prior art have shown the disadvantage that their lifting effect is considerably degraded over time.

In particular, the conventional yarn, which is simply combined with the cog, has a good effect at the beginning of the procedure, but also has a disadvantage in that the lifting effect is considerably decreased as the cog slips naturally over time. .

Therefore, when performing a wrinkle removal operation using a conventionally known conventional yarn, there is a problem that it is difficult to obtain satisfactory surgical results for both the patient and the doctor because the result (result) is different depending on the skill of the doctor. In addition, the surgical effect was not maintained so long, but also caused a variety of problems, such as a long recovery speed after surgery.

The present invention has been made to overcome the problems of the prior art, it is an object of the present invention to provide a lifting seal having an asymmetric structure that can be maintained over a long period of time while maximizing the effect of the lifting procedure.

The present invention for solving the above problems, a wire part of the holding portion, a grip part having a plurality of grip cogs arranged in a zigzag form at intervals of 180 degrees in the circumferential direction on one side of the support portion and the circumferential direction on the other side of the support portion And a retention part having a plurality of retention cogs arranged at intervals of 90 degrees and having an inclination opposite to the grip cogs, wherein the retention part includes a portion of the skin tissue with respect to the grip part during insertion and treatment of the support part. It provides a lifting thread having an asymmetrical structure to fix the position in the pulled state and to prevent sagging by gravity and restoring force of the tissue in the course of time after the procedure. Therefore, the reliability of the procedure and the persistence of the effect of wrinkle removal are improved.

In addition, the retention cog, the first to fourth cogs arranged at intervals of 90 degrees to form one retention cog, at least one or more of the first to fourth cogs are preferably formed longer than the grip cog. .

The first and third cogs may be disposed at angles corresponding to the grip cogs. Therefore, the certainty of the function of fixing the position of the pulling by the procedure can be improved.

In addition, the first and the third cog, it may be composed of a wing portion and the opposing wings that are arranged symmetrically with the separation portion therebetween. Therefore, the binding force with the tissue by one cog can be improved remarkably.

It is preferable that the interval where the retention cog portions are arranged in the longitudinal direction is larger than the interval spaced apart in the longitudinal direction of the grip cogs. Accordingly, even when combined with long-term skin tissue, the burden and damage of the tissue can be minimized.

Lifting thread having an asymmetric structure according to the present invention having the configuration as described above, since the phenomenon of the sagging of the skin is suppressed to the maximum as soon as the procedure or in the course of time in the past, its performance is maintained for a long time drastically after one procedure Has an advantage. This has the effect of reducing the pain and cost burden of the procedure.

In addition, since the grip part and the retention part have an asymmetrical structure, an optimized shape can be realized in performing each function. In particular, the first and third cogs have a predetermined wing shape while having a symmetrical structure. In addition, the second and fourth cogs are disposed therebetween and are formed at intervals of 90 degrees, thereby maximizing the effect of fixing the position during the procedure and preventing sagging of the skin over time.

The present invention is basically a holding part of a thread or wire form having a flexibility in the form of a long in the longitudinal direction, a grip part consisting of a plurality of grip cogs arranged at intervals of 180 degrees in the circumferential direction on one side of the support, and the support And a retention part comprising a plurality of retention cogs arranged at intervals of 90 degrees in the circumferential direction on the other side of the negative portion.

Hereinafter, with reference to the accompanying drawings will be described in detail a lifting yarn having an asymmetric structure of a preferred embodiment according to the present invention.

In the present invention, the term 'lifting' is used to define the meaning of removing wrinkles on the human body, in particular, the skin of the face. The lifting thread according to the concept of the present invention may be used in various parts of the human body, Could be applied.

As shown, the support 30 is shown as an embodiment having a circular cross section. The support 30 may have a non-circular cross-sectional shape to increase the surface area and promote the formation of cogs, for example, may be formed in the form of oval, square, polygon, cross, triangle, etc. It is not limitative.

The strut portion 30 may be formed as a polymer filament formed by an extruder having a circular cross section, and in general, since the diameter of the cross section is about 0.4 mm to 0.5 mm, it is appropriate to have a circular shape in consideration of productivity.

Cogs constituting the grip part 100 and the retention part 200, which will be described later, may be determined through a predetermined molding method after the support part 30 is formed by extrusion. 30 and the cogs can be formed integrally.

The lifting thread of the present invention functions to relieve or remove the sagging or wrinkles of the skin by forming a tension (tension) by catching the tissue inside the skin by the cogs, because it remains in the human body after the procedure can be absorbed into the tissue It is preferably formed as a bioabsorbable material.

As an example of such a bioabsorbable material, a bioabsorbable polymer material may be considered and may include polydioxanone, polylactide, polyglycolide, polycaprolactone and copolymers thereof. In general, the function of the lifting thread for the removal of wrinkles can be maintained for about 1 month to 24 months, preferably about 6 months, and after this function is terminated, it is absorbed into the tissue to remove the wrinkles without any unnecessary procedure of removal. The procedure has a possible advantage.

The grip part 100 is formed by arranging a plurality of grip cogs which protrude in the circumferential direction from one side of the support part 30, and these grip cogs provide a bonding force with the tissues when pulling the skin during the procedure.

As shown in the figure, the end side may be caught in the tissue because it is wedge-shaped in view of the skin tissue to be pulled out, and the pulling force of the operator if the insertion mechanism is removed after being inserted into the skin by the insertion mechanism as described below. To provide tension.

The retention part 200 is formed to face the grip part 100, and the retention cog parts 210 are formed in the opposite direction to the grip cog part 110 as illustrated. The retention cog unit 210 performs a different function from the grip cog unit 110, as will be described later, and has a difference in shape and arrangement.

The retention part 200 primarily performs the function of grasping the entire lifting thread pulled upwards in the process of the grip part 100 providing the tension in the skin tissue. Secondly, after the procedure, the grip part is prevented from sagging over time.

That is, the grip part 100 performs a predetermined grip function in the procedure, but the function of fixing and maintaining the position and shape of the skin after the procedure has a difference that the retention part 200 performs. do.

Therefore, the retention cogs constituting the retention part 200 are preferably formed more densely in the circumferential direction and longer in the longitudinal direction than the grip cogs, and are formed in the form of asymmetrical structures facing each other.

Figure 2 is a front view showing a preferred embodiment of the overall form of the lifting yarn having an asymmetric structure of the present invention.

As described above, the plurality of cogs are asymmetrically formed in the longitudinal direction from the support part 30 to form the grip part 100 and the retention part 200. The anchor part 10 and the grip part (from one side as a whole) 100), the retention part 200 and the handle portion 20 may be made.

In the description of the present invention, one side means a direction facing the grip part 100 with respect to the retention part 200, and the grip part 100 is inserted into the tissue of the skin from one side as described below. The tissue is supported for tension and the retention part 200 functions to prevent sagging during the fixation process after the procedure.

The anchor portion 10 is partially exposed to the outside from a predetermined insertion mechanism is inserted into the skin, the handle portion 20 is the anchor portion 10, the grip part 100 and the reclining portion in the predetermined incision procedure When inserted in the order of the tension part 200, at least a portion is exposed to the outside so that the operator can properly provide the tension to adjust the process of unfolding the wrinkles. Therefore, the handle portion 20 is preferably formed as an appropriate length that can be exposed to the outside to be gripped.

In a preferred embodiment, the length of the anchor portion 10 is 15mm, the length of the grip part 100 is 40mm, the length of the retention part 200 is 50mm, the length of the handle portion 20 is formed as 45mm. As a result, it may be formed to a total length of 150mm.

Here, the grip part 100 is sufficient to provide a tension is fixed to the tissue during the procedure, the retention part 200 functions to prevent sagging of the skin in the long term, so the retention part 200 is grip part 100 It can be confirmed that it is formed about 10mm long compared to). That is, the retention part 200 is preferably formed longer than the grip part 100.

Meanwhile, the grip part 100 and the retention part 200 may be formed by an arrangement of cogs, and cogs in opposite directions may face each other, and predetermined gaps may be formed between the facing parts. This may be defined as a connecting portion (not shown), and in some cases, the connecting portion may correspond to a gap between the grip cog portion 110 or the retention cog portion 210.

Figure 3 is an enlarged view showing the grip part in the lifting yarn having an asymmetric structure of the present invention, Figure 4 is an enlarged view showing the retention part.

Each cog may be formed in a predetermined wedge shape protruding to the outer circumferential side of the support portion 30, the grip cog portion 110 and the retention cog portion 210 may be formed of cogs formed in a direction facing each other. Yes is as described above. In addition, it may be formed as a form cut to the inner circumferential side after the extrusion molding of the support portion 30, according to this concept, the cut portion of the form of the recessed portion formed on the inner circumferential side is formed in the holding portion 30 of the respective cogs are formed do. This will be described later.

In a preferred embodiment of the present invention, the grip part 100 is formed by a plurality of grip cog parts 110 are arranged in the longitudinal direction, these grip cog parts 110 are stepped in the longitudinal direction at intervals of 180 degrees in the circumferential direction It can be formed as a set of two grip cogs arranged to be zigzag in shape. Therefore, when viewed from the front, it is confirmed that the grip cogs are alternately arranged with a predetermined longitudinal distance from the other side to one side.

Meanwhile, the retention cog parts 210 forming the retention part 200 have different shapes and arrangements because the retention cog parts 210 perform different functions from the grip part 100 and perform fixing and support for long-term skin tissue. It is preferable.

To this end, the retention part 200 may form the retention cog 210 which is a set of cogs by arranging the first to fourth cogs at intervals of 90 degrees in the circumferential direction.

Based on the matter shown in FIG. 4, the second cog 212 is formed at a 90-degree interval in the circumferential direction with respect to the first cog 211 disposed downward from one side, and again, the second cog 212 is formed at a 90-degree interval. Three cogs 213 may be disposed above. In the case of the fourth cog, it is not shown in the figure in view of the front, but may be disposed at the rear side at intervals of 90 degrees with respect to the third cog 213.

These first to fourth cogs are arranged at intervals of the circumferential direction by 90 degrees while being spaced a predetermined interval in the longitudinal direction of each other.

More preferably, the first cog and the third cog may be symmetrical to each other, and the second cog and the fourth cog may be symmetrical to each other.

At this time, it is preferable that at least the first cog and the third cog have a long shape as compared with the grip cog unit 110, and the thickness is also made thicker.

The arrangement of the first cog and the third cog may be formed to substantially correspond to the grip cog unit 110 in the circumferential direction, and the distance in the longitudinal direction is preferably larger than that of the grip cog unit 110. This can reduce the damage or the load of the skin as it supports the skin tissue in the long term.

The second cog and the fourth cog may be arranged between the first cog and the third cog in the circumferential direction. In the above example, the second cog and the fourth cog may be arranged in a staggered state with respect to the arrangement relationship of the grip cog unit 110. . That is, the second cog and the fourth cog may perform a function of improving resistance to the first cog and the second cog, thereby maximizing the effect of catching long-term skin sagging.

The relationship between the grip cog unit 110 and the retention cog unit 210 is not necessarily limited to the above-described example. In some cases, the grip cog unit 110 and the fourth cog face each other with respect to the arrangement of the grip cog. Or a certain angle may be considered.

Based on the case where the cross-sectional diameter of the support portion 30 is 0.45 mm, at least the first cog and the third cog are preferably formed to be at least 0.07 mm thicker than the grip cog portion 110 based on the thickest portion. Do.

That is, at least a portion of the first cutout 221 and the third cutout 223 with respect to the grip cutout 112 may be formed to be at least 0.07 mm deep.

The angle of the cutouts described above may be formed between 140 degrees and 170 degrees with respect to the support 30.

Figure 5 is a perspective view for explaining in more detail the lifting seal having an asymmetric structure of the present invention.

As described above, the grip cog unit 110 is formed by two grip cogs 111 formed in the longitudinal direction at intervals of 180 degrees in the circumferential direction, and the retention cog unit 210 includes the first to fourth noses. They are arranged longitudinally at intervals of 90 degrees.

As shown in the drawing, the grip cogs 111 are formed by the grip cutting part 112 in the grip cog part 110 formed by being arranged at intervals of 180 degrees, and the grip cog 111 is the third cog 213. It can be seen that the length is relatively short and thin compared to).

As shown in the drawing, the first cog 211 is formed at the bottom and the third cog 213 is formed at the top, and the second cog 212 and the fourth cog (not shown) are formed at both sides therebetween. There may be.

The lengths of the second cog 212 and the fourth cog may be smaller than or equal to the first cog 211 and the third cog 213, and the second cog and the fourth cog may be formed of the first cog and the first cog. As described above, it is possible to perform an auxiliary function for the three cogs.

At this time, it should be noted that the interval in the longitudinal direction of the grip cog 111 disposed on the upper surface is significantly shorter than the interval of the third cog 213 as shown.

In addition, in order to improve the compactness of the retention cog portion 210, adjacent cogs are preferably formed at a lower side without being spaced apart in the longitudinal direction. That is, the second cutout 222 of the second cog 212 arranged at intervals of 90 degrees with respect to the other end of the first cutout 221 corresponding to the first cog 211 is directly at the position corresponding thereto. It is preferable to start, and likewise, the third cutout 223 of the third cog 213, which is arranged at intervals of 90 degrees with respect to the other end of the second cutout 222, also preferably starts at a corresponding position. Do. When the four cogs form the retention cog unit 210 as one set, the incisions may be immediately formed between the respective retention cog units 210 or may be formed at predetermined intervals.

As will be described later, the grip part 100 is generally inserted from one side where the grip part 100 is formed, and the insertion direction may correspond to the gravity direction. In this case, since the retention part 200 must support the deflection of the skin against gravity, it is more effective to prevent the long-term deflection of the skin by forming a narrower and longer circumferential distance.

To this end, the first cog 211 and the third cog 213 may be composed of a wing 231 and the opposite wing 232 of the form symmetrically facing each other with the separation portion 233 therebetween. have.

That is, the first cog 211 and the third cog 213 has a wing shape that is open to both sides to perform a wedge-shaped function between the holding portion 30 as well as predetermined intervals between the spaced apart from each other. The elastic force is provided to support the tissue more reliably. In addition, one cog can have a support capacity equivalent to two cogs.

Since the shape of the wings of the first cog 211 and the third cog 213 can be formed simply by cutting the separation portion 233 has an advantage that the effect can be significantly improved compared to a relatively simple process Care must be taken.

Figure 6 is a view showing a state in which the lifting seal having an asymmetric structure of the present invention is coupled to the insertion mechanism.

The insertion mechanism 330 has a shape such as a predetermined needle so that the lifting thread 1000 can be inserted into the skin while having a minimal incision on the skin, and the lifting thread 1000 is anchored at one end side. It may be composed of a body 310 having a predetermined length, and a inserting portion 320 into which the lifting thread 1000 may be inserted at the other side, having a lead portion 330 that can be drawn out from the portion 10. have.

A predetermined opening is formed in the lead portion 330 so that the anchor portion 10 can be exposed, and the direction in which the opening is formed is optional. However, when it is formed to be exposed in the longitudinal direction to the end, such as a general syringe, it is preferable that the opening is formed laterally since the lifting seal 1000 may be separated together in the process of removing the insertion mechanism 330. Through this, the grip part 100 and the retention part 200 are in contact with the skin while remaining in the skin tissue from the anchor part 10.

The insertion part 320 may be formed in the form of an opening in which the cross-sectional area becomes wider toward the other side in consideration of the insertion process of the lifting seal 1000, and a part of the handle part 20 may be exposed to the outside.

The handle portion 20 functions as described above, after the insertion mechanism 330 is completely removed, the operator can grip and pull the wrinkles by hand to give tension.

Meanwhile, a fixing part 340 for fixing the anchor part 10 may be additionally disposed on the side where the drawing part 330 of the body 310 is disposed, and the fixing part 340 may be attached to the body 310. It is coupled so that the sliding movement in the longitudinal direction with respect to.

The fixing part 340 may perform a function of preventing a state in which the lifting seal 1000 is fixed in a storage or moving process.

Figure 7 is a state diagram showing the appearance of the procedure of the lifting thread of the present invention.

Referring to the fixed state of the insertion mechanism of Figure 6, when a predetermined incision is made in the desired position of the skin and the body 310 is inserted downward from the withdrawal portion 330 after reaching a predetermined depth is inserted The instrument 330 is removed and the lifting seal 1000 remains. Here, the incision may be made through a predetermined separate mechanism or may be formed in the process of inserting the insertion mechanism 330.

In this case, the grip part 100 receives a predetermined tension (a) from the lower side and is pulled to alleviate or remove wrinkles. This process may be performed by an operator's operation on the handle part 20 exposed to the outside. have.

After the pulling by the grip part 100 is made, sagging due to the weight of the skin tissue may be generated again. Such sag (b) is supported by the retention part 200. In other words, the retention part 200 performs a function of fixing the position during the procedure, as well as a function of suppressing the sag caused by gravity for a long time after the procedure is completed.

When the procedure is completed, the handle portion 20 exposed to the outside of the skin is cut and the retention part 200 and the grip part 100 remain together with the skin tissue to perform the function of removing wrinkles.

In this case, when the lifting seal 1000 is formed entirely of a bioabsorbable polymer material, the additional removal procedure may be omitted, as described above.

Due to the lifting thread having an asymmetric structure according to the concept of the present invention as described above, since the phenomenon of skin sagging immediately after the procedure or in the course of time is suppressed as much as possible, the performance is maintained for a long time drastically after a single procedure. Have This leads to the advantage of reducing the pain and cost burden of the procedure.

In the above, the present invention has been described in detail based on the embodiment and the accompanying drawings.
