Description

LIFTING THREAD WITH ASYMMETRIC STRUCTURE [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a medical room, and more particularly, to a lifting thread having an asymmetric structure so as to maximize the effect of improving wrinkles during a lifting operation for removing wrinkles.

As interest in skin beauty increases day by day, a variety of procedures for removing wrinkles are emerging.

Generally, the wrinkle removing treatment refers to the treatment of the skin, or the fat is concentrated and the skin of the specific region is changed, the region is made taut or the original shape is restored.

These wrinkle removal procedures are invasive surgery using large-scale cut-off of the skin after removal of the diseased tissue, non-invasive surgery minimizing the incision site, It is also said.

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

In recent years, the latter method has been widely used. It is also called a lifting method, but instead of cutting the skin, a specially treated yarn, for example a cog or a synthetic fiber of silicon or polypropylene, having a diameter of about 0.5 mm (SMAS) in the skin and the skin using the threads of the skin to remove the wrinkles and remove the tension is a way to revive.

These procedures can minimize scarring, which is the biggest disadvantage of using a scalpel, by using a needle through simple local anesthesia. In addition to reducing the irritation or damage of the surgical site, surgical bleeding or swelling And it is natural that it gives natural tension to the skin after surgery to make the skin look elastic and youthful.

Registration Practical Utility Model No. 20-0320005 discloses a medical room having a visible projection on the surface of a prior art thread.

However, in the case of using a small-diameter thread made of synthetic fibers as described above, if an excessive tension is applied to the yarn, there is a problem that a phenomenon of sawing or eating phenomenon occurs . In particular, the yarn disclosed in the prior art has suffered from a disadvantage that its lifting effect is considerably deteriorated over time.

Particularly, a conventional thread having a simple cog joint has a disadvantage in that the effect is good at the beginning of the procedure, but also the lifting effect is considerably deteriorated as the cog slips naturally over time .

Therefore, when the wrinkle removing operation is performed using a known conventional thread, there is a problem that it is difficult to obtain a satisfactory surgical result for both the patient and the doctor because the result is different according to the skill of the doctor. In addition, not only is the surgical effect not maintained for a long time, but also the recovery rate after surgery is also increased.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a lifting chamber having an asymmetric structure capable of maximizing the effect of a lifting operation and maintaining its performance over a long period of time.

According to a first aspect of the present invention, there is provided a grip portion including a grip portion having a plurality of grip cogs arranged in a zigzag shape at intervals of 180 degrees in the circumferential direction at one side of the strut, And a retention part having a plurality of retention cogs arranged at intervals of 90 degrees and having an inclination opposite to that of the grip cogs, A lifting chamber having an asymmetrical structure for fixing a position in a pulled state and preventing sagging due to gravity and restoring force of tissue during a period of time after the operation. Therefore, the reliability of the procedure and the persistence of the effect of wrinkle removal are improved.

In addition, the retention cogs are preferably arranged such that the first to fourth coils arranged at intervals of 90 degrees form one retention cog, and at least one of the first to fourth cogs is formed longer than the grip cog .

The first and third co-ordinates may be disposed at an angle corresponding to the grip cog. Therefore, the reliability of the function of fixing the position of the pulling by the procedure can be improved.

In addition, the first and third nose may be composed of a wing portion and an opposite wing portion arranged symmetrically with the spacing portion therebetween. Therefore, the binding force with the tissue by one nose can be dramatically improved.

It is preferable that the interval in which the retention cogs are arranged in the longitudinal direction is larger than the interval in the longitudinal direction of the grip cogs. Thus, the burden and damage of the tissue can be minimized even in long-term binding with the skin tissue.

The lifting thread having an asymmetric structure according to the present invention having the above-described structure has a problem that the performance of the lifting thread is remarkably maintained for a long time after a single operation since the phenomenon of sagging of the skin is minimized immediately after the procedure or during the passage of time . 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, it is possible to realize an optimized shape in performing each function. In particular, the first and third noses have a symmetrical structure and have a predetermined wing shape And the second and fourth noses are disposed therebetween at intervals of 90 degrees, whereby the effect of preventing the sagging of the skin due to the fixation of the position during the procedure and the passage of time can be maximized.

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

1 is a front view for explaining the concept of a lifting thread having an asymmetric structure according to the present invention.

The present invention basically comprises a grip portion made of a flexible cord or wire-shaped support portion having a long shape in the longitudinal direction, a plurality of grip cogs arranged at intervals of 180 degrees in the circumferential direction from one side of the support portion, And a plurality of retention cogs arranged at intervals of 90 degrees in the circumferential direction on the other side of the part.

In the present invention, the term 'lifting' is defined and used to remove the wrinkles of the human body, especially the face skin. The lifting thread according to the concept of the present invention can be used in various parts of the human body, .

The support portion 30, as shown, 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 facilitate the formation of the noses, for example, in the form of an ellipse, a rectangle, a polygon, a cross, It is not limited.

The support portion 30 may be formed as a polymer filament formed by an extrusion molding machine having a circular cross section. Generally, the diameter of the cross section is about 0.4 mm to 0.5 mm.

The nose of the grip part 100 and the retention part 200, which will be described later, can be determined by a predetermined molding method after the piercing part 30 is formed by extrusion. According to this concept, (30) and coils can be integrally formed.

The lifting thread of the present invention functions to hold tissues in the skin by the nose to form tension to relieve or eliminate skin sagging or wrinkles. After the surgery, the lifting thread remains in the human body, It is preferably formed as a bioabsorbable material.

As one example of such a bioabsorbable material, a bioabsorbable polymer material can be considered and can be made of polydioxanone, polylactide, polyglycolide, polycaprolactone and a copolymer thereof. In general, the function of the lifting thread for removing wrinkles can be maintained for about 1 month to 24 months, preferably about 6 months, and after the function is completed, it is absorbed into the tissue, It has an advantage that it can be practiced.

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

Since the wedge shape is taken from the viewpoint of the skin tissue pulled as shown in the drawing, the end side may be caught in the tissue. If the insertion mechanism is inserted after being inserted into the skin by the insertion mechanism as described later, So that the tension can be provided.

The retention part 200 is formed to face the grip part 100 and the retention cog parts 210 are formed in a direction opposite to the grip cog part 110 as shown in the figure. The retention cog unit 210 functions differently from the grip cog unit 110 as described later, and has a difference in shape and arrangement.

The retention part 200 primarily functions to hold the entire lifting room lifted upwards in the process of providing the tension of the grip part 100 in the skin tissue, Secondly, it functions to prevent sagging of the grip part with time after the operation.

That is, it is noted that the grip part 100 performs a predetermined grip function during the procedure, but the function of fixing and maintaining the position and shape of the skin after the procedure is performed by the retention part 200 do.

Therefore, retention coils constituting the retention part 200 are preferably denser in the circumferential direction and longer in the longitudinal direction than the grip nose, and are formed in such a manner that they are opposed to each other in an asymmetric structure on both sides.

2 is a front view showing a preferred embodiment of the overall shape of a lifting chamber having an asymmetrical structure according to the present invention.

The grip part 100 and the retention part 200 are formed as a plurality of noses from the support part 30 asymmetrically in the lengthwise direction as described above and the anchor part 10 and the grip part 100, a retention part 200, and a handle 20.

In the description of the present invention, one side refers to the direction in which the grip part 100 is viewed 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 later, The retention part 200 supports the tissue against tension and functions to prevent sagging in the fixing process after the procedure.

The anchor portion 10 is partly exposed to the outside from the predetermined insertion mechanism and inserted into the skin. The handle portion 20 is fixed to a predetermined incision portion in the procedure of the anchor portion 10, the grip portion 100, And the tension part 200 are inserted in this order, at least a part of the part is exposed to the outside, and the operator can appropriately adjust the process of providing the tension and expanding the wrinkles. Therefore, it is preferable that the grip portion 20 is formed as an appropriate length that can be exposed and gripped to the outside.

In a preferred embodiment, the length of the anchor part 10 is 15 mm, the length of the grip part 100 is 40 mm, the length of the retention part 200 is 50 mm, and the length of the grip part 20 is 45 mm And may be formed to have a length of 150 mm as a whole.

Since the retention part 200 functions to prevent sagging of the skin for a long period of time, the retention part 200 can be attached to the grip part 100 ), Which is about 10 mm long. That is, the retention part 200 is preferably longer than the grip part 100.

On the other hand, the grip part 100 and the retention part 200 can be formed by arranging the noses thereof, and are disposed such that they face each other in opposite directions, and a predetermined spaced interval may be formed between the opposite sides. (Not shown). In some cases, such connection may correspond to the distance between the grip cog 110 and the retention cog 210.

Fig. 3 is an enlarged view showing a grip part in a lifting chamber having an asymmetric structure according to the present invention, and Fig. 4 is an enlarged view showing a retention part.

Each of the coins may be formed in a predetermined wedge shape protruding toward the outer periphery of the peripheral edge portion 30 and the grip cog portion 110 and the retention cog portion 210 may be formed of noses formed in directions opposite to each other As described above. Further, according to this concept, it is possible to form the incision part in the shape of a depression in the inner periphery side in the support part 30 of the part where the noses are formed, do. This will be described later.

In a preferred embodiment of the present invention, the grip part 100 is formed by arranging a plurality of grip cog parts 110 in the longitudinal direction, and these grip cog parts 110 are arranged at intervals of 180 degrees in the circumferential direction, A set of two grip coils arranged in a zig-zag fashion. Therefore, it is confirmed that the grip coils are arranged alternately with a predetermined longitudinal gap from the other side when viewed from the front.

Meanwhile, the retention cog parts 210 constituting the retention part 200 perform functions different from those of the grip part 100 and must be fixed and supported for long-term skin tissue, .

To this end, the retention part 200 can be formed as a retention cog part 210, which is a cog set, with the first to fourth noses arranged at 90-degree intervals in the circumferential direction.

The second cogs 212 are formed in front of the first cogs 211 disposed at a lower side from the first cogs 211 at an interval of 90 degrees in the circumferential direction, 3 cogs 213 may be disposed on the upper side. Although not shown in the figure for the sake of the fourth coincidence, they may be disposed on the rear side at 90 degree intervals with respect to the third cog 213.

These first through fourth coils are spaced circumferentially by 90 degrees apart from each other by a predetermined distance in the longitudinal direction.

More preferably, the first cog and the third nog can be formed in mutually symmetrical shapes, and the second cog and the fourth nog can be formed in mutually symmetrical shapes.

At this time, it is preferable that at least the first cog and the third cog are formed in a longer shape than the grip cog 110, and the thickness is also thicker.

The first cog and third cog arrangement may be formed to substantially correspond to the grip cog 110 in the circumferential direction, wherein the gap in the longitudinal direction is larger than the grip cog 110. [ This can reduce damage or load on the skin due to long-term support of the skin tissue.

The second cog and the fourth cog can be arranged in the circumferential direction between the first cog and the third cog, and in the above example, the arrangement of the grip cogs 110 is also staggered . That is, the second cog and the fourth cog function to enhance the resistance to the first cog and the second nog which are auxiliary, thereby maximizing long-term skin deflection.

The relationship between the grip cog 110 and the retention cog 210 is not necessarily limited to the above example, and may be arranged in the form of facing the second cog and fourth nog Or a predetermined angle may be formed.

It is preferable that at least the first cog and the third cog are formed to be thicker than 0.07 mm with respect to the thickest portion as compared with the case where the tip end portion 30 has a cross sectional diameter of 0.45 mm Do.

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

The angle of the incisions may be formed between 140 degrees and 170 degrees with respect to the abutment 30.

5 is a perspective view illustrating a lifting chamber having an asymmetric structure according to an embodiment of the present invention.

As described above, the grip cogs 110 are formed in the longitudinal direction with two grip cogs 111 formed at intervals of 180 degrees in the circumferential direction, and the retention cogs 210 are formed of the first, They are arranged in the longitudinal direction as 90 degree intervals.

The grip cogs 111 are formed by the grip cutouts 112 in the grip cog parts 110 formed by arranging the two pieces 180 degrees apart as shown in the figure, and the grip cogs 111 are connected to the third cogs 213 ), The length was relatively short and thin.

The first cog 211 is formed on the bottom and the third cog 213 is formed on the top and the second cog 212 and the fourth cog are not formed on both sides Can be.

The length of the second cog 212 and the fourth cog 212 may be less than or equal to the length of the first cog 211 and the third cog 213. The length of the second cog and the length of the fourth cog, 3 < / RTI > can be performed as described above.

Here, it should be noted that the gap in the longitudinal direction of the grip cogs 111 arranged on the upper surface is formed to be significantly shorter than the gap of the third cogs 213 as shown in the figure.

In addition, in order to improve the denseness of the retention cog 210, it is preferable that the adjacent noses are formed without spaced apart in the longitudinal direction immediately below. That is, the second cutout 222 of the second cog 212, which is arranged at an interval of 90 degrees with respect to the other end of the first cutout 221 corresponding to the first cog 211, It is preferable that the third cutout 223 of the third cog 213 arranged at 90 degrees apart from the other end of the second cutout 222 is also started at the corresponding position Do. When the four noses form a retention cog 210 as one set, the cuts may start immediately between the respective retention cogs 210 or may be formed with a predetermined spacing.

As will be described later, in the course of the procedure, the grip part 100 is inserted from a 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 should support the sagging phenomenon of the skin against gravity, it is more effective that the interval in the circumferential direction is narrow and longer, thereby preventing long-term sagging of the skin.

The first cog 211 and the third cog 213 may be formed of a wing portion 231 and an opposite wing portion 232 symmetrically opposed to each other with the spacing portion 233 therebetween. have.

That is, the first cogs 211 and the third cogs 213 have a wing shape that is widened to both sides, so that the first cog 211 and the third cog 213 function not only in the form of a wedge widened with respect to the support portion 30, So that the tissue can be more reliably supported. In addition to this, one nose can have the equivalent of two cogs.

Since the shapes of the wings of the first cog 211 and the third cog 213 can be formed simply by cutting the separating portion 233, the advantage that the effect can be remarkably improved as compared with a relatively simple process .

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

The insertion mechanism 330 is shaped like a predetermined needle so that the lifting chamber 1000 can be inserted into the skin while having a minimum incision site on the skin. On one side of the lifting chamber 1000, A body 310 having a predetermined length and an inserting portion 320 into which the lifting chamber 1000 can be inserted is provided with a lead portion 330 which 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 opening direction is optional. However, if the lifting chamber 1000 is formed to be exposed in the longitudinal direction at the end portion as in the case of a general syringe, it is preferable that the opening is formed laterally since the lifting chamber 1000 may be detached in the process of removing the insertion mechanism 330. Through which the anchor part 10 remains in the skin tissue and comes in contact with the skin in the order of the grip part 100 and the retention part 200.

The insertion portion 320 may be formed in the shape of an opening having a larger cross-sectional area toward the other side in consideration of the insertion process of the lifting chamber 1000, and a part of the grip portion 20 may be exposed to the outside.

After the insertion mechanism 330 is completely removed, the grip portion 20 functions to allow the practitioner to grasp the wrinkle portion and to adjust the tension of the wrinkle portion by pulling the wrinkle portion by hand.

A fixing part 340 for fixing the anchor part 10 may be additionally disposed on a side of the body 310 on which the lead part 330 is disposed. So as to be slidable in the longitudinal direction.

The fixing unit 340 may function to prevent the lifting chamber 1000 from being unlocked during the storage or movement.

7 is a use state diagram showing an embodiment of the lifting chamber of the present invention.

6, when a predetermined incision is made at a desired position of the skin and the body 310 is inserted downward from the lead portion 330, when the body 310 reaches a predetermined depth, The mechanism 330 is removed and the lifting chamber 1000 is left. Here, the incision may be made through a predetermined separate mechanism or may be formed in the process of inserting the insertion mechanism 330.

At this time, the grip part 100 is pulled to lower or remove the wrinkles by receiving a predetermined tension (a) from the lower side. This process is performed by the operation of the operator with respect to the grip part 20 exposed to the outside have.

After pulling by the grip part 100, deflection due to self weight of the skin tissue may be generated again. Such deflection (b) is supported by the retention part (200). That is, the retention part 200 performs a function of fixing the position in the procedure, as well as a function of restraining the sagging due to gravity for a long time after the operation is completed.

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

At this time, if the lifting chamber 1000 is formed of a bioabsorbable polymer material as a whole, there is an advantage that an additional removing operation can be omitted.

The lifting thread having an asymmetrical structure according to the concept of the present invention has the advantage that the performance of the lifting thread can be maintained for a long time after a single operation since the sagging phenomenon of the skin is minimized immediately after the procedure or during the time I have. This leads to an advantage of reducing the pain and cost burden of the procedure.

In addition, since the grip part and the retention part have an asymmetrical structure, it is possible to realize an optimized shape in performing each function. In particular, the first and third noses have a symmetrical structure and have a predetermined wing shape And the second and fourth noses are disposed therebetween at intervals of 90 degrees, whereby the effect of preventing the sagging of the skin due to the fixation of the position during the procedure and the passage of time can be maximized.
