Description

Medical Lifting Seals {MEDICAL LIFTING SULTURE}

The present invention relates to a medical lifting, and more particularly, it is mainly inserted into the patient's face to restore the elasticity of the insertion site and at the same time to minimize the loss of the lifting tension due to the vector (vector) conversion medical quality that can ensure excellent traction Relates to a lifting seal.

Medical seals, also referred to as sutures, have been widely used in the past primarily to provide surgical sutures.

As melting yarns such as polydioxanone (PDO), polylactic acid (PLLA) or polycaprolacton (PCL), known as collagen formation promoters, have been developed, they have been developed as lifting threads used in so-called facelifting procedures to improve facial elasticity. It was. According to this, a lifting thread is inserted into a specific part of the face, which is simpler than a face lift, which is a kind of surgical method, and has a skin elasticity effect comparable to the surgical effect.

Such a lifting thread is inserted into the subcutaneous and after lifting the skin has been produced a lifting thread formed with a cog (cog) is fixed to the subcutaneous tissue.

The protrusions of the lifting thread are manufactured under various names such as Midas, Omega, Blue Rose, Super-Orange, and Silhouette Lift depending on their shape, material, and pattern. It is described as having.

As such, lifting seals having a shape and pattern of protrusions that can maintain a long lifting effect after the procedure have been improved / developed. The Korean patent No. 1701434, a facial and body lifting suture, has a plurality of pairs of protrusions or protrusion units that are suture headquarters. In the face and body lifting suture consisting of a polymer or gold integrally formed on the outer peripheral surface of the convex, the cone is formed in a radial symmetrical structure around the suture head, cone, polygon, modified polygonal pyramid, polygonal pyramid, Modified polygonal pyramidal, cylindrical, modified cylindrical, polygonal and modified polygonal three-dimensional structure or a face, having a funnel shape in which all or part of the space except the outer peripheral surface and the suture headquarters portion of the three-dimensional structure is empty And a suture for body lifting, wherein the plurality of protrusions or protrusion ends Above is the effect of preventing the lifting tension loss caused by the vector transformation caused by the lifting effect is reduced or the thread is not inserted straight due to the lowering of the binding of the fixed point paired so that the vertices or the bottom of the projections face each other It is open to the public.

By the way, according to the known technique as well as the known yarn, it can be seen that the protrusions formed at the leading end portion and the rear end portion in one yarn are repeatedly formed in a specific pattern. Due to the nature of pushing out or pulling in various directions, the direction and size of the vector generated at the anchor point (fixed point) provided by the leading and trailing side protrusions may be different from each other. The problem is that it does not act as a fixed point and is unnecessarily released from its position. In addition, the front end and the rear end of the thread can be easily broken due to the driving ability to move in the opposite direction, as well as the unnecessary flow is frequent and there is a disadvantage that a part of the broken thread pops out into the skin.

Therefore, the litter is equipped with a new and advanced three-dimensional protrusion that can act as a stable fixed point while responding to the vector diversified according to the height of the depth inserted into the living body, thereby achieving a longer lifting effect. There is a need to develop a new seal.

The present invention has been made to overcome the problems of the above technology, the headquarters are divided into two parts into the front end and the rear end, and the shape of the core formed on the rear end side differently than the projection formed on the front end side at the same time the entire front end side It is to provide a medical lifting seal which can serve as a more stable anchor point in response to a vector in which each protrusion and core is different depending on each point of the living body by increasing the volume of the entire core on the rear side rather than the volume of the protrusion.

Another object of the present invention is to serve as a stable anchor point at the site inserted deeper in the body than the core through the various shapes of the projections.

Another object of the present invention by presenting a variety of shapes of the core through this to exhibit a stronger traction and tensile force than the projections while efficiently improving the problem that the projection does not play a stable anchor point role to provide a more reliable anchor point function will be.

It is a further object of the present invention to provide a more stable fixing force by forming a plurality of anchor points that can form a middle core or an inter core in the core and can be fixed in contact with agile response to a vector change that is diversified according to the stretching and contraction.

In order to achieve the above object, the medical lifting seal according to the present invention, the head part consisting of a first part that is a front end portion, and a second part that is a rear end portion continuous from the first part; A plurality of protrusions formed at regular intervals along a length direction of the first part; And a plurality of cores formed at a predetermined interval along a length direction of the second part, the core having a shape different from the protrusion and a large volume relative to the total volume.

The first and second parts may be distinguished at an intermediate point of the head office.

In addition, the core, which extends inclined in the front end direction from the head office, a plurality of first extension portion formed in a plurality at regular intervals along the longitudinal direction of the head office, and the first extension portion from the head office to the rear end direction It is characterized by consisting of a plurality of second extension extending inclined.

According to the medical lifting seal according to the present invention,

1) Unlike the well-known face lifting seals, the headquarters are divided into two parts, and cores with large volumes are placed on the different headquarters and the rear headquarters parts to cope with changes in the vector caused by the insertion of the seals more stably. By building anchor points that are firmly fixed, you can ensure strong fixation and traction.

2) Excellent lifting effect can be achieved by providing stable traction and efficient traction by various shapes and patterns of core.

3) By securing a large number of anchor points that can respond to the vector changes of the living body by the three-dimensional shape of the core, not only can have a stronger fixing force and traction,

4) It has the effect of having a natural lifting effect while preventing unnecessary fluidity and easily broken based on the fixing force and natural shape of the core.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. The accompanying drawings are not drawn to scale, and like reference numerals in each of the drawings refer to like elements.

1 is a perspective view showing a basic embodiment of a medical lifting seal according to the present invention.

As can be seen from Figure 1, the medical lifting seal of the present invention is a projection 100 is formed on the head or the head of the cylindrical (1) extending to a predetermined length, the known yarn is a plurality of continuous one shape Unlike the known medical thread in which detailed structures such as springs are formed, the head office 1 is divided into two parts, namely, first and second parts (10 and 20), which are different from each part. It is characterized in that the protrusion 100 and the core 200 having a shape and volume are disposed.

That is, the yarn of the present invention is an asymmetrical yarn, to solve the problem of the conventional bidirectional (front and rear) symmetrical shape caused the discomfort and pain after the procedure or short maintenance period.

Specifically, in the yarn of the present invention, a plurality of protrusions 100 are formed at the tip portion of the head office 1, that is, the first part 10 at regular intervals along the longitudinal direction of the head office 1, and the head office 1 A plurality of protrusions are formed at the rear end portion of the headquarter, that is, the second part 20 at regular intervals along the longitudinal direction of the head office 1, and the protrusions formed on the second part side, which is the rear end portion of the head office 1, are formed. In the present invention, referred to as 'core' (200).

The headquarters 1 including the protrusion 100 and the core 200 are made of polydioxanone (PDO) having the same or similar melting properties as known cosmetic lifting yarns, or further, a polylactic acid (PLLA) known as a collagen formation promoting substance. ) Or PCL (Polycaprolacton) or may include at least this. Here, PDO has the advantage of having a relatively long half-life and less tissue response than other soluble sutures, and in the case of PCL, it may remain longer in the skin.

As such, the core 100 and the protrusion 200 may be made of the same material as well as different materials. For example, the protrusion 100 may be made of PDO and the core 200 may be made of PCL. . Such materials can be degraded and absorbed in the dermal layer of the skin after approximately 3 to 12 months to minimize side effects and allergic reactions.

In particular, when the lifting seal of the present invention is made of PPLA to PCL which is a collagen formation promoting material, it can contain or coating a functional material for collagen formation on or inside thereof to maximize collagen formation, which will be described later. do.

The core 200 not only has a shape different from that of the protrusions 100, but mainly has a total volume of the plurality of cores 200 larger than that of the plurality of protrusions 100.

The reason why the total volume of the core 200 is larger than the total volume of the protrusion 100 is that the core 200 having a large volume relatively to the rear end portion (second part) side of the head office 1, which serves to pull the lifting thread, has a larger volume. ), The tip portion (first part) of the head office 1 is unstablely fixed to the body tissue, or consequently, the entire head office 1 flows to prevent the problem of not functioning properly as an anchor point. It is intended to play a role of minimizing the fluidity of the tip portion (first part) of the head office 1 is fixed to the body tissue. In addition, the core 200 may be bent or pulled by the leading part (first part) of the head office 1 as a result of the movement by stretching or regenerating or changing the facial expression of the biological tissue after insertion of the living body, thereby causing a lifting tension. It can serve as a kind of center of gravity to prevent loss.

In addition, the total volume of the core 200 is not simply larger than the total volume of the protrusion 100, but the shape thereof is also different (specifically, the anchor point generates various fixed points, that is, anchor points with biological tissue). It is implemented to reinforce the role of anchor point by processing in three-dimensional shape rather than protrusion so that a large number can occur.

In FIG. 1, the protrusions 100 are inclined to face the tip in one direction of the head office 1, and the core 200 has two pairs in a V shape so as to be larger than the entire volume of the protrusions 100. Although the shape of the protrusion 100 and the core 200 is not limited thereto, the shape of the protrusion 100 and the core 200 will be described later.

In addition, the second part 20 of the first and second parts 10 and 20 may be formed in about 1/3 to 2/3 of the total length of the main office, and is too large in balance with the first part. The first and second parts (10, 20) are formed to have a length ratio of the middle point of the headquarter, that is, 1: 1 in order to prevent the problem of lowering the tensile force of the head office by acting as an excessive center of gravity by occupying. It is preferable.

Hereinafter, various shapes of the protrusion 100 and the core 200 of the present invention will be described in detail with the accompanying drawings.

2 is a longitudinal cross-sectional view showing first embodiments in which the protrusions of the present invention have various shapes.

Embodiment of the projection 100 according to Figure 2 (a), like the projection 100 in Figure 1, the tip of the headquarters 1 from the side of the headquarters 1 (hereinafter referred to as 'tip') It is a structure formed in plural with a predetermined interval taking the inclined shape to direct the.

These protrusions 100 not only provide convenience of production but also provide a foundation to be caught in body tissues to perform a basic role of anchor points.

As shown in FIG. 2B, the protrusion 100 according to FIG. 2A is alternately formed on both sides of the first part 10, that is, the protrusion 100 of FIG. It has a shape that is inclined to face the tip while alternating both sides.

The protrusion 100 having such a shape may prevent the problem that the first part 10 is bent to one side in the biological tissue while providing a fixing force of body tissue that is firmer than the protrusion 100 for FIG. 2A. .

As shown in FIG. 2C, the protrusion 100 includes a pair of inclined portions 110 and an inclined portion 110 in which the end shape of the protrusion 100 is inclinedly extended so that the diameter thereof becomes wider in the rearward direction from the tip of the head office. It shows that consisting of the rear portion 120 connecting both ends of the.

According to the structure of the protrusion 100, the protrusion 100 has a tip directivity (directional) can be easily inserted into the treatment site through a medical insertion device such as a cannula and at the same time the inclined portion 110 and the rear portion 120 An angle is generated in between to provide the property that the fluidity of the protrusion 100 is blocked at the treatment site by this angled site.

In addition, the protrusion 100 according to (c) of FIG. 2 has a pointed tip or a blunt shape while the inclined portion 110 is directed toward the tip side of the head office 1 while the terminal shape is shaped like a triangle. Is done. Its three-dimensional shape may have a shape such as a cone (corn), a conical shape, as well as a polygonal cone shape projecting three-dimensionally 360 degrees with respect to the headquarters (1), according to this structure to increase the volume of the protrusion 100 to the treatment site In addition to improving the volume and role of the anchor point at the same time as well as prolong the lifting duration can provide a property that can be easily inserted with less resistance to skin tissue when inserted into the treatment site.

Figure 3 is a longitudinal cross-sectional view showing a modified embodiment of the projection of the present invention in various shapes.

The protrusion 100 for FIG. 3A has a shape similar to that of FIG. 2C, but the rear part 120 is recessed inwardly (inward to the front side of the main office), and thus the rear part 120 is formed. The circumferential portion of) takes the shape of protruding outward while a predetermined angle with the inclination portion 110 is generated. As a result, the circumferential side protruding portion of the rear part 120 is more firmly fixed to body tissues, thereby providing a characteristic of faithfully serving as an anchor point.

The projection 100 of FIG. 3B has a structure in which its longitudinal shape is similar to a right triangle. The three-dimensional shape thereof may be formed of a tetrahedron or a polygonal pyramid, or may have a flat plate structure having the same thickness as the vertex portion and the vertical short side 133.

Specifically, the longitudinal shape of the protrusion 100 of FIG. 3 (b) will be described. In the state where the vertical long side 131 is in contact with the first part 10, the inclined side 132 is inclined toward the front end and the vertical short side is formed. 133 has a structure connecting the end of the vertical long side 131 at the end of the inclined side 132.

According to this structure, since the protrusion 100 protrudes in both directions of the first part 10 and has a three-dimensional volume, the protrusion 100 not only becomes a more rigid anchor point but also enhances the facial volume while enhancing the lifting duration. to provide.

In the embodiment according to (c) of FIG. 3, an indicator 140 is formed in at least one portion among the plurality of protrusions 100, and the indicator 140 is formed around the first part 10. Accordingly, it refers to a structure protruding in the vertical direction from the longitudinal direction of the first part 10 in a three-dimensional shape such as a ring shape or a sphere to ellipsoid shape.

The indicator 140 may protrude higher than the protrusion 100 or may have various protruding heights such as the same height to a lower height.

In addition, the indicator 140 may be formed between the protrusions 100, or may be formed while skipping between the protrusions 100 or at random positions among the plurality of protrusions 100.

According to this, during the procedure, the doctor can easily check the distal end portion of the head office, that is, the point where the first part is inserted into the living body, and at the same time, when the protrusion 100 is fixed to the living tissue as an anchor point, the surrounding living body When the tissue is pushed between the protrusions 100, the tissue is in contact with the moved biological tissue and becomes another anchor point, thereby naturally providing a plurality of anchor points in the first part 10, thereby providing a property of strengthening the fixing force of the biological tissue. do.

In the following, with reference to Figures 4 to 6 showing a variety of shapes for the core 200 of the present invention will be described in detail.

4 is a longitudinal cross-sectional view showing embodiments in which the core of the present invention has various shapes.

The core 200 according to FIG. 4A extends obliquely in the rear end direction from the head office 1, that is, the second part 20, and is formed in plural at regular intervals along the longitudinal direction of the head office 1. Between the first extension portion 210 and the first extension portion 210 is characterized by consisting of a plurality of second extension portion 220 inclined in the rear end direction from the main office (1).

The core 200 is preferably formed together with the projections 100 of FIGS. 1 and 2 (a) at one headquarters 1, but has a different shape from the projections 100, but the entirety of the projections 100 The protrusion 100 of FIGS. 1 and 2 (a) is formed on one side of the head office and has a volume larger than the volume, and properly compensates for a problem that can be bent in one direction. Because they have similarities.

The core 200 according to FIG. 4B has a structure in which the cutting part of the first and second cutting parts is lifted outward while the second part 20 includes the first and second cutting parts. Can be.

First, the head office 1, that is, the second part 20 includes the first and second cutting parts.

The first cutting part may include a first cutting part 30 cut inward in a rear end direction from one side of the second part 20, and a second part at a point spaced apart from the first cutting part 30 in a rear end direction. It means a structure consisting of a plurality of second cutting portion 40 cut inward toward the tip direction of the (20) at regular intervals along the longitudinal direction of the second part (20).

In addition, the second cutting part may include a third cutting part 50 cut inward from the other side of the second part 20, which is the opposite side of the insertion point of the first cutting part 30, toward the tip direction, and the first cutting part. The fourth cutting part 60 cut inward along the rear end direction of the second part 20 on the other side of the second part 20, which is the opposite side of the indentation point of the second cutting part 40 following the 30. Is composed of a plurality of at regular intervals along the longitudinal direction of the second part (20).

Correspondingly, the core 200 may be each of the first to fourth cutting parts 30, 40, 50, and 60 at the tip portions of the first and fourth cutting parts 30, 40, 50, and 60, respectively. It takes a structure that protrudes outward along the inclined direction of. In this case, the cores 200 by the first and second cutting parts 30 and 40 have a structure that is open to each other, while the cores 200 by the third and fourth cutting parts 50 and 60 have a structure where they are collected from each other. Have

The core 200 can be more easily formed by the cutting method of the head office 1 when manufacturing the lifting seal of the present invention, the core 200 itself provides a function as an anchor point, as well as the first To first and fourth cutting parts 30, while holding the living tissue moved to the inner space of the second part 20 generated by the fourth to fourth cutting parts 30, 40, 50, and 60 more firmly. 40,50,60) can press the tissue to prevent the biological tissue from easily deviate to ensure a more rigid fixing force and a strong traction.

In other words, the core 200 by the first and second cutting parts 30 and 40 fixes the pulled portion while directly pulling up the collapsed skin tissue, and the core by the third and fourth cutting parts 50 and 60. 200 is a structure that is gathered with each other can closely share the role of supporting while holding up the sagging skin tissue in close contact with the body tissue.

4C illustrates a structure in which the core 200 of each of the first and second cutting parts extends in curvature so as to be rounded in a direction facing each other.

That is, the shape of the core 200 is deformed so that the core 200 facing each other in a rounded state forms a pair and naturally penetrates into the biological tissue therebetween, thereby exhibiting a stronger fixing force.

5 is a longitudinal cross-sectional view showing first modified embodiments in which the core of the present invention has various shapes.

The core for FIG. 5 shows a variety of modifications to it, with essentially a combination of the first and second cores.

First, the core of FIG. 5A is composed of a combination of first and second cores 230 and 240.

Specifically, the first core 230 is a pair of first inclined surface 231 extending inclined narrowly in the rear end direction from the tip of the second part 20, and both ends of the first inclined surface 231 It consists of a bottom portion 232 has a longitudinal shape similar to a triangle.

Correspondingly, the second core 240 also has a triangular shape, and is inclined to widen in the rear end direction from the tip of the second part 20 at a position in contact with a vertex of the first core 230 or spaced apart from each other. It consists of a pair of extended 2nd inclined surface 241, and the base part 242 which connects the both ends of this 2nd inclined surface 241. As shown in FIG.

That is, the longitudinal shape of the core 200 according to (a) of FIG. 5 has a shape similar to that of a bow tie. Accordingly, the core 200 may be provided with a larger volume than the protrusion 100. It offers an excellent advantage in its role.

In addition, the protrusion 100 made of a cone shape as shown in Figure 2 (c) has the advantage that the volume is secured to a certain level, but because the shape is directed to the tip of the head office (1) of the present invention to the tip side of the head office (1) Although the lifting seal itself can be easily pushed, the core 200 according to (a) of FIG. 5 has a core group (first and second cores) in which triangles are symmetrically formed and is not directed in a specific direction. Not only does it faithfully serve as an anchor point at that position, but also two sharply protruding portions are formed at the corners of the bottoms 232 and 242 of the first and second cores 230 and 240 to secure relatively increased anchor points. It can provide a close bond with biological tissue in one condition.

The core 200 according to FIG. 5B protrudes outwardly along the circumference of the second part 20 between the first and second cores 230 and 240 in the core 200 according to FIG. 5A. The middle core 250 is further provided.

The middle core 250 has a position and shape similar to that of the indicator 140 described above, and when the first and second cores 230 and 240 serve as fixed points, that is, anchor points while contacting the living tissue, The tissue may be moved to the side of the recessed portions of the first and second cores 230 and 240, in which case the middle core 250 is in contact with the thus moved biological tissue and serves as another anchor point, resulting in one core 200. While naturally forming a number of anchor points in the provides a property that can strengthen a stable and solid fixing force on the living tissue.

The core 200 according to FIG. 5C has a structure in which the bottom parts 232 and 242 of the first and second cores 230 and 240 are recessed inward, and as a result, the bottom parts of the first and second cores 230 and 240 are formed. Both sides have a shape protruding outward. In other words, two protruding portions are formed on the bottom portions 232 and 242 of the first and second cores 230 and 240, so that a total of four protruding portions are formed based on the entire first and second cores 230 and 240. Can serve as an anchor point.

Correspondingly, the middle core 250 has a shape that protrudes to the outside but protrudes the same or lower than both sides of the bottom portions 232 and 242 of the first and second cores 230 and 240.

As a result, the core 200 according to FIG. 5B may further retain anchor points by six protruding portions, thereby further strengthening the fixing force with the living tissue.

In addition, the middle core 250 has a structure that protrudes equal to or lower than both sides of the bottom parts 232 and 242 of the first and second cores 230 and 240 with respect to the vertically outward direction of the second part 20. That is, as mentioned above, when a part of the biological tissue first contacting the protruding portions of the bottom portions 232 and 242 is pushed toward the middle core 250, it is fixed and stable while naturally contacting the protruding portions of the middle core 250. In addition, it is possible to provide excellent holding force and traction.

The middle core 250 according to FIG. 5D has a convex portion in which surfaces facing the first and second cores 230 and 240 are convexly rounded.

Accordingly, a boundary portion of each of the first and second cores 230 and 240 may also have a rounded structure, and the first and second cores 230 and 240 protrude relatively sharply to a part of the biological tissue moved while contacting the biological tissue. It has the foundation to accommodate more naturally and consequently provide more stable holding force.

Furthermore, the convex portion facing the second core 240 can be convexly rounded as a radius of curvature larger than the radius of curvature of the convex portion facing the first core 240.

According to this structure, both surfaces from the middle core 250 toward the first and second cores 230 and 240 are not symmetrical, and at the same time, the first core 230 side, that is, the tip direction of the second part 20 is directed. Since the first and second cores 230 and 240 do not face any one of the front end and the rear end of the head office 1 because they have a shape, the first and second cores 230 and 240 serve to partially compensate for the lack of an agile response to the vector conversion.

In other words, the middle core 250 is preferably formed with a protrusion having a structure that is directed toward the tip of the first part 10, for example, the protrusion 100 of FIG. 1. While the head is oriented while the core 200 is not oriented, excessive tension is generated at each of the front and rear ends of the head office 1 so that the head office 1 can be easily broken or bent due to loss of tension. To provide a role.

6 is a longitudinal sectional view showing second modified embodiments in which the core of the present invention has various shapes.

6 (a) shows a deformation structure of the middle core 250, and is based on a rhombus shape having four inclined sides 260 as a whole.

According to the rhombus structure, the convex protrusion structure symmetrical to both sides of the second part 20 may be provided to provide a function of intuitively contacting and fixing the living tissue on both sides of the second part 20.

Furthermore, the inclined side 260 may include a cushioning part 270 having first to third rounding sections 271, 272, 273.

The first rounding section 271 is a portion recessed in a first radius of curvature from one point around the top of the inclined side 260 to the first point a toward the top of the inclined side 260.

The second rounding section 272 has a second radius of curvature smaller than the first radius of curvature from an end a of the first rounding section 271 to a second point b towards the top of the inclined edge 260. It is a protruding part.

The third rounding section 273 means a portion extending from the end b of the second rounding section 272 to the top of the inclined side 260 with a third radius of curvature smaller than the second radius of curvature.

 The first rounding section 271 is a portion that is treated to be spaced apart by a depth deep without being in close contact with a part of the biological tissue moved while being pressed by the first and second cores 230 and 240. This is because the second and third rounding sections 272 and 273 to be described later are tightly adhered to the moved biological tissue, and this also causes structural deformation, that is, when the second rounding section 272 is pressed against the biological tissue, Self-extension causes the second rounded section 272 to partially stretch or swell in its peripheral direction, such as when the localized portion in the middle core 250 is stretched, particularly when the localized area around the first rounded section 271 is elongated. In addition, the first rounding section 271 is provided with a buffer space for accommodating the site, and the role of the first rounding section 271 to be able to naturally extend while the extension of the first rounded section 271 itself toward the moved biological tissue. Do this.

That is, the first rounding section 271 provides a buffer function to accommodate the localized site where the contracted deformation occurs while the second and third rounded sections 272 and 273 having the protruding shape come into contact with the moved biological tissue.

Unlike the first rounding section 271, the second rounding section 272 protrudes toward the moved tissue, and has a radius of curvature smaller than the radius of curvature (first radius of curvature) of the first rounding section 271. That is, it protrudes with a 2nd radius of curvature, and consequently, the width | variety and the volume are narrower than the 1st rounding section 271, and are formed. That is, the second rounding section 272 protrudes sharply rather than the indentation by the first rounding section 271, which draws a gentle curve, leading to tighter contact with the living tissue, thereby causing the second rounding section 272 and When the peripheral portion is stretched and deformed, the deformation portion is provided to stably buffer or accommodate the first rounded section 271 having a larger volume than the second rounded section 272.

The third rounding section 273 also forms a protruding portion like the second rounding section 272, but has a radius of curvature (third radius of curvature) smaller than the radius of curvature (second radius of curvature) of the second rounding section 272. Formed to form a sharp rounding slope. In this case, the tip portion of the protruding shape of the second and third rounding sections 272 and 273 has a shape similar to the V-shape, so that the moved biological tissue naturally pushes the second and third rounding sections 272 and 273 to the first rounding. It provides a guide role that can be moved to the side of the section 271, and if the moved biological tissue is about to exit outward, the second and third rounding sections 272 and 273 are depressed and are not easily released to the outside. Do not do it.

In other words, when the second and third rounding sections 272 and 273 have a slanted portion directed in a specific direction, such as a cable tie, the second and third rounding sections 272 and 273 are placed on the biological tissue. It is easily pressed by the same and closely adhered to the living tissue, and when the living tissue tries to escape in the opposite direction, the second and third rounding sections 272 and 273 stand up and perform a kind of jamming action that prevents the movement of the living tissue. It is easy to prevent the biological tissue from leaving the middle core 250 and the peripheral portion thereof.

In summary, the buffer part 270 ensures cohesion with biological tissues by the structure and function of each of the first to third rounding sections 271, 272, and 273, while intensively and efficiently preventing departure of the biological tissues once received. The tight coupling with the tissue is a function of elastically preventing the problem that the boundary portion of the first and second cores 230 and 240 are distorted and the first and second cores 230 and 240 are broken or damaged.

6B further relates to a structure in which the inter core 300 protruding outward along the circumference of the second part 20 is formed between the first and second cores 230 and 240.

The inter core 300 provides a structure and a function similar to the above-described indicator 140, so that the doctor, the operator, can easily determine the rear end portion of the head office 1, that is, the position where the second part 20 is inserted into the living tissue. In addition to providing an identification function that can be identified, it also serves as another anchor point to provide stable fixation of surrounding biological tissues.

6C illustrates a termination shape of at least one of the indicator 140 and the inter core 300.

Specifically, at least one end shape of the inter core 300 may include a pair of first rounding parts 310 and round ends extending in a direction in which they are gathered toward each other toward an outer direction and ends of the first rounding parts 310. The second rounding part 320 extends from the first rounding part 310 to the end with a second radius of curvature smaller than the radius of curvature of the first rounding part 310.

In this case, the second rounding part 320 has a protruding structure that protrudes convexly compared to the first rounding part 310, and accordingly, the second rounding part 320 may move the biological tissue moved therebetween due to the fixing role of the first and second cores 230 and 240. While the second rounding part 320 makes a first contact and implements an anchor point role for the living tissue, the remaining living tissue is surrounded by the first rounding part 310 having a curved shape. It can be stably fixed between the core (230,240).

In this way, the core 200 according to various structures not only serves as the overall center of gravity of the head office 1, but also serves to respond to the vector transformation as quickly as possible, and also secures a large number of anchor points on its own so that the front and rear ends have the same pattern. It is possible to give a characteristic that can provide a stable holding force and traction force than the known lifting seal is repeated projection of.

As described so far, the configuration and operation of the medical lifting seal according to the present invention have been expressed in the above description and the drawings, but this is merely an example, and the spirit of the present invention is not limited to the above description and the drawings. Various changes and modifications are possible without departing from the technical spirit.
