Description

Medical lifting thread with enhanced fixation {MEDICAL LIFTING SULTURE WITH ENHANCED RETENTION}

The present invention relates to a medical lifting thread with enhanced fixing force, and more particularly, to a medical lifting thread capable of relieving the tension of living tissue that resists pressure and fixing of living tissue due to protrusions.

The medical thread was developed to provide a suture function during the initial surgical operation, and since then, it has been developed for cosmetic and plastic surgery purposes to increase the elasticity of the skin in modern times.

That is, after being inserted into the skin and lifting the skin, a lifting thread in which a protrusion is formed that is caught in the subcutaneous tissue and pulls the skin is being manufactured.

The lifting thread is generally made of a melting thread such as PDO (Polydionaxone), PLLA, or PCL. PDO is a type of medical suture that is safe and has little foreign body feeling, but the effect lasts for about 6 months. On the other hand, since PLLA and PCL have higher strength than PDO, they have the advantage of not only elasticity but also three times longer maintenance period. In particular, PLLA is a surgical treatment of expensive Sculptra filler with medical thread.

This lifting thread is being developed to have various protrusion shapes, and the shape of these protrusions is a three-dimensional structure or Various shapes exist, such as a funnel shape in which some or all of the space except for the outer peripheral surface of the three-dimensional structure and the internal suture head part is empty.

As an example of the prior art having sharp protrusions among protrusions made of various shapes as described above, Korean Patent Laid-Open No. 10-2006-0059142 "Operating Room for Plastic Surgery" is made of metal, polymer, or biological material, and the longitudinal direction In an operating room for plastic surgery having inclined protrusions continuously arranged along It is located on the top, and it is published as characterized in that the direction of inclination of the projections continuously alternates.

In particular, this prior art discloses that the lifting action is superior when the protrusions are arranged in both directions than when they are arranged in one direction.

However, according to the above technology, it is recognized that the protrusions are installed in both directions of the head office to fix the living tissue more firmly than when they are installed in one direction. The head office may be cut off by applying unnecessary pressure to the head office, but there is a problem that a separate means to prevent this problem is not provided.

Therefore, there is a need to develop a new and advanced lifting thread that can properly cope with the repulsive force of living tissue pushed by the protrusion but provided with the protrusion.

The present invention has been devised to overcome the problems of the above technology, and by forming a separate groove around the protrusion, that is, the cog, and inducing and accommodating a part of the surrounding biological tissue, where the stress is concentrated by the protrusion, into the groove, thereby compressing the cog. Accordingly, an object of the present invention is to provide a lifting thread capable of dispersing and alleviating the tension applied to the living tissue, and consequently securing a stable fixing force.

Another object of the present invention is to efficiently increase the area of the end of the cog in contact with the living tissue to secure a sufficient contact area with the living tissue, thereby pulling the living tissue in a direction consistent with the traction force of the head office.

Another object of the present invention is to provide various structures of grooves to enhance the induction and reception functions of living tissues.

A further object of the present invention is to improve the fixation power of living tissue by manufacturing the head office of a material having adhesiveness.

In order to achieve the above object, a medical lifting thread with enhanced fixing force according to the present invention, the head office; a first inclined portion extending obliquely from the surface of the head office in the rear end direction of the head office, and obliquely extending in the rear end direction of the head office from the first point of the head office, and from the first point at the end of the first inclined portion a cog comprising a second inclined portion extending to a second point of the head office spaced apart by a predetermined distance in the rear end direction of the head office; A first recessed part extending inwardly of the head office in the same line as the second inclined part, and a third point of the head office spaced a certain distance from the second point at the end of the first recessed part in the rear end direction of the head office It consists of a groove including a second recessed portion extending to the inner circumferential surface; characterized in that the cog and the groove are formed in plurality at a predetermined distance from one side of the head office.

The first inclined part may include a first inclined part extending parallel to the first inclined part and a second inclined part bent from the first inclined part and connected to the second inclined part.

In addition, the second recessed part, a first recessed part extending a certain length from the first recessed part in the rear end direction of the head office, and a second recessed part extending from the end of the first recessed part to the third point characterized by including.

According to the medical lifting thread with enhanced fixing power according to the present invention,

1) By using the groove to accommodate the living tissue pushed by the cog, it is possible to reduce the tension of the living tissue while strengthening the fixation force to the living tissue,

2) Face the cog and groove toward the rear end of the head office to reduce the resistance of the skin tissue during the procedure.

3) By increasing the contact area of the cog, it not only increases the compressive force and traction force on the living tissue, but also

4) Curvature the surface from the cog to the protrusion so that the shape is oriented toward the front end of the head office, thereby providing the effect of counteracting the repulsive force of the living tissue.

Hereinafter, preferred 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 numbers in each drawing refer to like elements.

1 is a cross-sectional view showing a basic embodiment of a lifting seal of the present invention.

First of all, the head office 10 is made of a material that can be dissolved in a living body, for example, PDO (polydioxanone), or PLLA (Poly L Lactic Acid) or PCL (Polycaprolacton), which is known as a collagen formation promoting material, like the known head office. It may consist of or at least include it. As will be described later, such a material may include a functional material for enhancing adhesion.

As can be seen from Figure 1, the medical lifting seal of the present invention is composed of a plurality of cogs 100 and grooves (200).

The cog 100 is formed to protrude obliquely from at least one direction of the head office 10 to the outside, specifically in the rear end direction of the head office 10, like a known protrusion, and the terminal shape of the cog 100, that is, the cog 100, is It consists of a first inclined part 110 and a second inclined part 120 .

The first inclined portion 110 refers to a portion obliquely extending from the first point of the head office in the rear end direction of the head office 10 .

In addition, the second inclined portion 120 is a second point (b) of the headquarters 10 spaced a predetermined distance from the first point (a), which is the end of the first inclined portion 110 in the rear end direction of the headquarters (10). area extended to Here, the first point (a) refers to the starting point of the first inclined part 110 , and the second point (b) refers to the ending point of the second inclined part 120 , in other words, the first point (a) is It is located in the front end direction of the head office 10 rather than the second point (b), and the width of the first and second points (a, b) becomes the diameter (width) of the cog 100 .

That is, the distance between the first and second points (a, b) can determine the diameter of the cog 100 , and can be set variously according to the length of the head office 10 and the number of cogs 100 .

This cog 100, like the known protrusion, serves as an anchor point of the corresponding biological tissue when the head office 10 is inserted into the biological tissue of the treatment site and lifts the surrounding biological tissue for a longer time than the head office without projections. It provides the function of fixing the for a long time. At this time, since the formation direction of the cog 100 is oriented toward the rear end of the head office 10, when the head office 10 is inserted into the treatment site, it provides a property that can be easily inserted while receiving less resistance from the living tissue.

The groove of the present invention is directly in contact with the rear end of the above-described cog 100 and is recessed to have a certain volume toward the rear end of the head office 10 .

Specifically, the longitudinal shape of this groove, that is, the groove 200 is composed of the first recessed portion 210 and the second recessed portion 220 .

The first recessed portion 210 is formed on the same line as the aforementioned second inclined portion 120 . In other words, it means that the first recessed portion 210 is a portion that is recessed and extended inward from the surface of the head office along the same extension line as the second inclined portion 120 .

As such, since the second inclined portion 120 and the first recessed portion 210 are formed on the same line, as a result, the groove 200 is located in the rear end direction of the head office 10 in direct contact with the cog 100 . .

In addition, the second recessed portion 220 is a portion extending from the end of the first recessed portion 210 to the third point (c) of the head office 10 spaced a certain distance in the rear end direction of the head office 10 as a starting point. am. In other words, the first and second recessed portions 210 and 220 mean the cross-sectional shape of the inner circumferential surface of the groove 200 .

In this case, the position of the third point (c) can be variously set according to the volume difference between the cog 100 and the groove 200 . For example, when the cog 100 is formed by cutting a portion of the surface of the head office 10, since the cog 100 and the groove 200 have the same volume, the first and second points (a, b) The distance of is equal to the distance of the second and third points (b,c). In addition, when the head office 10 is molded by various processing methods to form the cog 100 and the groove 200 , the cog 100 and the groove 200 may have different volumes. Furthermore, the cog 100 and the groove 200 may have the same or different shapes.

As described above, according to the manufacturing process and design of the lifting seal of the present invention, the volume and shape of the cog 100 and the groove 200 may be set to be the same or different.

Hereinafter, the function and operation focusing on the lifting seal of the present invention, in particular, the groove 200 according to the above-described structure will be described as follows. As described above, when the cog 100 fixes and presses the living tissue, tension is generated in the living tissue. That is, as is well known, since living tissue has a restoring force, when the pressure of the cog 100 is applied to the living tissue, stress is generated in the living tissue and tension is added. If the restoring force is stronger than the pressing force of the cog 100, the head office may be cut off.

That is, there is a need to relieve the tension of the living tissue caused by the pressure of the cog 100 while partially acknowledging the restoring force of the living tissue.

The groove 200 of the present invention provides a function of dispersing and relieving the tension of the living tissue having the same properties.

As described above, the biological tissue compressed by the cog 100 has a property of being restored to its original shape, and if it cannot be restored, unnecessary stress may be concentrated and the main body may be broken. Since 200) is formed, some tissues surrounding the biological tissue fixed to the protrusion may be naturally guided in the direction of the groove 200 to be accommodated in the groove 200 .

Due to this, a part of the site is restored to solve the problem of stress concentration in the living tissue in which the tension is generated, but the restored part of the tissue is accommodated and fixed in the direction of the groove 200, and as a result, the groove 200 is the restoration of the living tissue. It is possible to provide a guide and a fixing function at the same time. Furthermore, the fixing force of the living tissue may be strengthened by additionally securing an area (volume) that can be in contact with the living tissue as much as the volume of the groove 200 .

In summary, the leafing seal of the present invention serves to effectively maintain the fixing force to the living tissue while relieving the tension force unnecessarily generated in the living tissue around the protrusion by the groove 200 .

2 is a cross-sectional view showing an embodiment in which the cog 100 and the groove 200 of FIG. 1 are alternately formed on both sides of the head office.

As can be seen from FIG. 2 , the cog 100 and the groove 200 described above are not limited to being formed in one direction of the head office 10 , but both directions of the head office 10 , that is, the surface of the head office 10 . One side and the other side opposite to the one side are alternately formed at a predetermined interval. Accordingly, it is possible to prevent the problem that the head office 10 is tilted to one side of the living tissue while securing a strong fixing force of the living tissue as in the prior art described above.

At this time, the cog 100 formed on one side and the other side of the head office 10 is directed in the same direction, that is, the rear end direction of the head office 10, so that the head office 10 can be inserted without resistance when inserted into a living tissue. However, it provides a characteristic that can secure a stable fixing force.

3 is a cross-sectional view showing an embodiment in which the first inclined part 110 is composed of first and second inclined parts 111 and 112 and the curvature extension structure of the second inclined part 120 and the first recessed part 210, It is a view showing two modified examples of the cog (100).

First, referring to FIG. 3( a ), it can be seen that the first inclined part 110 has a bent shape unlike the above-described embodiment, and specifically, it is composed of a first inclined part 111 and a second inclined part 112 . can

The first inclined part 111 is a portion obliquely extending from the first point (a) of the head office in the rear end direction of the head office 10, and has the same overall structure as the first inclined part 110 of FIG. An inclination angle made with the extension direction of the head office 10 is greater than that of the first inclined part 110 . In other words, the first inclined part 111 has a structure oriented toward the front end of the head office 10 rather than the first inclined part 110 of FIG. 1 .

The second inclined part 112 is a portion that is bent at the end of the first inclined part 111 , extends parallel to the extension direction of the head office 10 , and comes into contact with the second inclined part 120 .

According to the structure of the first and second inclined parts 111 and 112, the area in contact with the living tissue by the extended length of the second inclined part 112, that is, the anchor area, is wider than the known protrusion made of a pointed shape. Due to this, it provides the function of strengthening the fixation force to the living tissue by the physical principle of securing an additional contact area while alleviating the phenomenon of unnecessary concentration of stress on the local area of the living tissue due to the sharp protrusion.

Furthermore, while the first inclined part 111 is oriented toward the front end direction of the head office 10 rather than the first inclined part 110 of FIG. 1 , the second inclined part 112 extends in the extension direction of the head office 10 . Due to the parallel extension structure, the cog 100 may serve to assist the traction force of the head office 10 with respect to the living tissue.

In other words, in general, the head office 10 pulls the living tissue in its extension direction, whereas the cog 100 provides a function of securing the fixing force of the living tissue while changing the position of the anchor point according to its shape, FIG. 3 In the cog 100 of (a), the first inclined part 111 is oriented in the direction of the front end of the head office 10 rather than the first inclined part 110 of FIG. In addition to setting the direction of (100), the second inclined part 112 extends in parallel with the extension direction of the head office 10, thereby having the same traction direction as the head office 10 and pulling the same as the head office 10 in addition to the fixed function It means that you can combine functions.

Such a specific structure of the first inclined portion 110 may be equally applied to an embodiment to be described later.

The embodiment according to FIG. 3 ( b ) relates to a structure in which the second inclined portion 120 and the first recessed portion 210 are extended to be convexly curved in the front end direction of the head office 10 .

That is, the embodiment of FIG. 3 ( b ) shows the structure of the second inclined part 120 and the first recessed part 210 in a state with the first and second inclined parts 111 and 112 as in FIG. 3 ( a ). has been transformed

According to this, both a portion of the cog 100 and a portion of the groove 200 have a structure oriented toward the tip direction of the head office 10 , that is, the second inclined portion 120 and the first recessed portion 210 . ) has a structure oriented in the same direction as the traction direction of the living tissue by the head office 10, and as a result, some parts of the cog 100 and the groove 200 are similar to the head office 10, and the traction function of the living tissue is It can play a supporting role.

In particular, the living tissue introduced into the groove 200 can be further entered in the direction of the tip of the head office 10 with the structure oriented toward the tip of the head office 10 of the first recess 210, so that the restoring force direction of the living tissue and the head office The biological tissue entering the groove 200 by matching the traction direction of

In addition, due to the curvature structure of the second inclined portion 120, the width of the side end of the cog 100 on the surface side of the head office 10 is narrower than the end of the cog 100, so that the cog 100 moves toward the head office 10. It is possible to strengthen the compressive force applied to the living tissue by strengthening the property to extend outward without unnecessary aggregation of the head office 10 .

4 and 5 are cross-sectional views showing various embodiments in which the second recessed part 220 is composed of the first and second recessed parts 221 and 222, and shows various embodiments of the groove 200 of the present invention. am.

The embodiment of FIG. 4( a ) shows a structure in which the second recessed part 220 is composed of the first and second recessed parts 221 and 222 .

The first recessed part 221 is a portion extending a predetermined length from the end of the first recessed part 210 in the rear end direction of the head office 10 , and the second recessed part 222 is an end of the first recessed part 221 . It refers to a region that is bent at and extended to the third point (c).

That is, in the first and second recessed parts 221 and 222 , the second recessed part 220 does not extend in a straight line or curved line without a separate inflection point, but is based on the inflection point, that is, the boundary portion of the first and second recessed parts 221 and 222 . 4(a) shows that the head office 10 is bent convexly in the surface direction, but it is not limited thereto, and it is also possible to have a structure bent convexly in the inside direction of the head office 10. Do.

According to this, it is possible to increase the probability of making a surface contact with the living tissue entering the groove 200 compared to the case where the second recessed part 220 extends in a straight line or a curved line without a separate inflection point, as well as in a bent shape. Accordingly, it provides a function of smoothly guiding the living tissue entering the groove.

For example, in a state in which the second recessed part 222 is extended to face the introduction site of the groove 200 , the living tissue that has entered the groove 200 is first touched, and then the first bent into the groove 200 . It can be guided naturally to the depression part 221 , and thereafter, a basis for sliding movement to the inside of the first depression part 221 can be provided.

In summary, it is possible to serve as a guide for smooth internal entry of the living tissue that has entered the groove 200 by the bent extension structure caused by the first and second recessed parts 221 and 222 .

In the embodiment of Figure 4 (b), as in the embodiment of Figure 4 (a), the second recessed part 220 is subdivided into the first and second recessed parts 221 and 222, but the first recessed part 221 is the head office. A structure extending parallel to the extension direction of (10) is presented.

This is the same applied to the groove 200 in which the second inclined part 112 extends in parallel in the embodiment of FIG. It serves to provide a space that can accommodate living tissue.

In other words, the first impregnated part 221 coincides with the traction direction of the head office 10 to reduce resistance and loss to the traction of the head office, as well as the biological tissue in contact with the first recessed part 221 is also the head office 10 By arranging them neatly in accordance with the traction direction of

The embodiment of Fig. 5 (a) is a specialized structure according to Fig. 4 (a), when the first immersion part 221 is based on the imaginary line extending in the longitudinal direction of the head office 10, the second dent It is a structure extending at an inclination angle smaller than the inclination angle of the part 222 . According to this structure, the second recessed part 220 takes a convex structure in the inner direction of the head office 10 .

According to this structure, the living tissue that has entered the groove 200 is inserted as if it falls vertically along the second dented part 222 , and then is deformed in the first dented part 221 , so that the front end side of the head office 10 . Allow them to move naturally into space.

In other words, the embodiment of FIG. 5 ( a ) results in not only serving as a guide for instantly introducing the living tissue into the groove 200 , but also allowing the living tissue to not be biased in any one part within the groove 200 . The groove 200 may serve to guide the uniform distribution in the inner space.

The embodiment of FIG. 5( b ) shows that the second recessed part 222 is again bent. Specifically, the second recessed part 222 includes first and second inclined sections 222a and 222b .

The first inclined section 222a is a portion extending from the end of the first recessed part 221 at a first inclination angle based on an imaginary line extending in the longitudinal direction of the head office 10 .

The second inclined section 222b refers to a portion extending from the end of the first inclined portion 120 at a second inclination angle smaller than the first inclination angle based on an imaginary line extending in the longitudinal direction of the head office 10 .

According to this structure, the introduction site of the groove 200 is expanded so that the living tissue can easily enter the groove 200 at the initial time point when the living tissue enters the groove 200 , and at the same time, the groove 200 . It provides a role of introducing the biological tissue that has entered the inside into the space at the front end of the head office 10 step by step.

That is, by lowering the inclination angles of the first and second inclined sections 222a and 222b step by step from the inside to the outside of the groove 200 to facilitate the initial entry situation of the living tissue, turn the entry direction to the front end side of the head office 10 It is guided to be inserted into the space, and for this reason, when the living tissue flows due to the fixation of the cog 100 , it is possible to provide a basis for instantaneous entry into the groove 200 without flowing to other parts.

6 is a cross-sectional view illustrating a structure in which a chamfer 230 is formed at a boundary between the first recessed part 210 and the first recessed part 221 .

The cog 100 has a shape facing the rear end direction of the head office 10, but can be partially flowed while using the boundary portion between the first recessed part 210 and the first recessed part 222 in the groove 200 as a central point. However, if the cog 100 flows or moves beyond a certain range, there is a risk of cracks or tears at the boundary between the first recessed part 210 and the first recessed part 221 .

In order to solve this problem, as can be seen from FIG. 6 , a chamfered chamfer 230 is formed at the boundary between the first recessed part 210 and the first recessed part 221 . it is possible

The chamfer 230 is chamfered so as not to cause an angle at the boundary between the first recessed part 210 and the first recessed part 221 , but has been chamfered in a round shape, which results in the movement of the cog 100 Due to this, it provides a characteristic that can prevent the occurrence of cracks in this area.

Furthermore, the cross-sectional shape of the chamfer part 230 , that is, the chamfer part 230 may have a rounding shape that is bent in multiple stages. Specifically, the chamfer part 230 may include first, second, and third rounding parts 231,232 and 233 .

The first rounding portion 232 is a portion extending from the bending start point on the side of the first recessed portion 210 to the center point of the bending portion with a first radius of curvature, and the second rounding portion 232 is the first rounding portion 231 . ) refers to a portion extending with a second radius of curvature that is smaller than the first radius of curvature from the end of the first recessed part 221 to one bent portion on the side.

In addition, the third rounding part 233 is bent at the end of the second rounding part 232 and extends with a third radius of curvature smaller than the first and second curvature radii to the end point of bending on the side of the first recessed part 221 . is the part

The first to third rounding portions have a uniquely designed structure to relieve stress when the stress is concentrated on the chamfer portion 230 due to the movement of the cog 100 .

Specifically, the first rounding part 231 performs a function of preventing cracks from occurring in the chamfer part 230 with the highest priority by reinforcing the bent part on the cog 100 side to be thicker than other parts. However, if the first rounding part 231 is too long, it is no different from processing only the chamfer part 230 to be thick, so it is extended to the center of the bent part. As a result, only the bent part on the cog 100 side increases the thickness intensively. It can be understood as a complementary processing method.

The second rounding part 232 extends toward the first recessed part 222 with a radius of curvature smaller than the radius of curvature of the first rounding part 231, and the line extending from the end of the first rounding part 231 is a groove. The thickness of the chamfer part 230 that is thickened by the first rounding part 231 is adjusted with the first rounding part 231 having a radius of curvature that draws a smaller circle than the first rounding part 231 while facing the bottom side of the 200. .

Due to this, the living tissue that has entered this site can move upward at a certain height while having a shape seated on the chamfer 230 rather than sinking toward the first invading part 221 , whereby the living tissue moves toward the first rounding. By guiding and stacking parts 231 around the area, it is possible to make this living tissue itself perform a role like a wall preventing the flow of a kind of cog 100 . As a result, by adjusting the indentation position of the living tissue by the second rounding part 232 , it is possible to prevent the problem that the cog 100 is rapidly bent or flows due to this.

The third rounding part 233 has a similar radius of curvature to that of the second rounding part 232 , and rather than extending to the contact point of the first recessed part 221 , it is a portion that is extended as if falling rapidly to the first recessed part 221 , thereby A certain level difference occurs between the third rounding part 233 and the first impinging part 221 , and the step difference is the elongation or elastic restoration function, which can be said to be a property of the chamfer part 230 itself, and furthermore, the head office 10 itself. It can serve as a physical space where this can be performed smoothly.

In other words, by causing the third rounding part 233 to generate a certain empty space in the extension line of the chamfer part 230, as well as the chamfer part 230, the first recessed part 210 and the first recessed part ( 221), it is possible to provide a function that allows it to be smoothly performed without interfering with the stretching function of the boundary region.

7 is a flowchart illustrating a process for manufacturing the functional material contained in the lifting seal of the present invention.

As another embodiment, the head office of the lifting thread of the present invention may include a functional material including pectin to enhance the adhesiveness of the lifting thread, thereby assisting in fixing and traction to living tissue.

This functional material is manufactured through a mixing 1 solution preparation step (S100), a mixture 2 solution preparation step (S110), a mixture 3 solution preparation step (S120), a mixture 4 solution preparation step (S130), and a functional material completion step (S140) can be, and the specific method for this is as follows.

First, the mixing 1 solution preparation step (S100) is a process of preparing a mixture 1 solution by mixing 80 to 95 parts by weight of water and 5 to 20 parts by weight of pectin.

Here, pectin is a colloidal polysaccharide widely distributed in plants, and is abundant in leaves, stems, fruits, etc., in a small amount in wood, and is also contained in seaweed. Such pectin can be dissolved in water to represent a highly viscous colloidal solution and impart adhesiveness.

Next, the mixed 2 solution preparation step ( S110 ) is a process of preparing a mixed 2 solution by mixing 85 to 95 parts by weight of dimethyl sulfoxide and 5 to 15 parts by weight of N-hydroxysuccinimide (NHS). Here, dimethyl sulfoxide serves as a solvent for dissolution of NHS, and NHS as a crosslinking agent activates the carboxyl group of pectin by esterification reaction to produce an NHS-pectin intermediate, which will be described later. It can bind more strongly with gelatin.

Then, the mixing 3 solution preparation step (S120) is 30 to 60 parts by weight of the mixture 1 solution, 30 to 60 parts by weight of the mixture 2 solution, and 1 to 10 parts by weight of EDC (1-ethyl-3-(3-dimethyl aminopropyl)carbodiimide) After mixing, it is a process of preparing a mixed 3 solution by stirring at 20 to 30° C. for 20 to 30 hours, and the mixed 4 solution preparation step (S130) is 70 to 90 parts by weight of 0.1M PBS (Phosphate buffered solution), 10 to 10 parts by weight of gelatin Mixing 30 parts by weight is the process of preparing a mixed 4 solution.

Here, EDC serves as an adjuvant capable of further improving the above-described NHS-pectin intermediate and crosslinking between pectin and gelatin. In addition, 0.1M PBS serves as a solvent for dissolving gelatin, and gelatin is cross-linked with pectin by NHS and EDC. It is a kind of induced protein obtained by treatment with alkali.

Finally, the functional material completion step (S140) is a process of mixing 40 to 60% by weight of the mixed 3 solution and 40 to 60% by weight of the mixed 4 solution and then heating at 40 to 60° C. for 10 to 20 hours to complete the functional material am.

The functional material manufactured through this process is manufactured through a crosslinking reaction of pectin and gelatin, so it is environmentally friendly and harmless to the human body.

In addition, the functional material may further include mussel foot protein to further improve fixation and adhesion to living tissue.

Specifically, relative to the total weight of the functional material, the mussel foot protein may be included in a ratio of 1 to 10% by weight, and the mussel foot protein is included in the middle of the functional material manufacturing process, mixed in the finished functional material, or coated on the surface It may be included in the functional material in such a way that there is no specific limitation thereto.

At this time, the mussel foot protein has a shape with a flat pad attached to the end of a thin thread called byssus, and is composed of more than 12 types of proteins. At this time, proteins named Mfp-1 (Mytilus foot protein-1), Mfp-3, and Mfp-5 are present in a high proportion in the mussel foot protein, and 3,4-dihydroxyphenyl-L-alanine (DOPA) is present in these proteins. ) is very rich in modified amino acids called

This mussel foot protein has a strong coating ability and adhesion, has a burning characteristic with excellent adhesion in water, and because it is a protein component, it can have high functionality even when applied to the body. Therefore, the mussel foot protein may be included in the functional material to help improve the fixation and traction power of the functional material to the living tissue.

As described so far, the configuration and action of the medical lifting thread with enhanced fixing force according to the present invention are expressed in the above description and drawings, but this is only an example and the spirit of the present invention is not limited to the above description and drawings, It goes without saying that various changes and modifications can be made without departing from the technical spirit of the present invention.
