The present invention relates to a linear surgical material for plastic surgery used to pull the skin tissue so that the wrinkles are spread by inserting inside the skin of the body, and more particularly, to prevent plastic deformation caused by load or fatigue above the critical value The present invention relates to a linear tensile material for plastic surgery that can be maintained for a long time and improve the quality of the procedure by increasing the bond with body tissue.

As humans age, they experience various aging phenomena. Among them, wrinkles of the skin are formed by the collagen fibers that maintain the elasticity in the skin, and due to the repetitive motion of the muscles connected to the skin, especially in the face part, the skin thickness is thin and the collagen fibers are denatured. More wrinkles are formed because of the longer exposure time to the ultraviolet rays that stimulate the skin and various repetitive movements of the muscles, such as making various expressions. Because of the wrinkles of the face part is visible to the outside, various efforts have been attempted to remove it, and in recent years, the demand for wrinkle removal technology for various body parts including not only the face but also the neck is increasing.

In order to remove wrinkles generated in each part of the body as described above, a medicine or a technique of peeling the surface of the skin may be used, but a surgical operation is used as a more effective method.

Previous surgical methods include facial elevation, which pulls the skin to remove excess skin and sutures the incision to open the skin.However, this surgery involves a large incision in the body, which increases the risk of surgery itself. In addition, scars remain in the treatment part, and the recovery period is long, and there are many problems caused by the procedure. In addition, as the body tissue is fixed in the pulled state, wrinkles generated by aging of the skin continue to progress, and the skin becomes thinner as much as the pulled.

As an improvement over the conventional surgical method, recently, a surgical method of tightening the skin surface by pulling a skin tissue by inserting a cord or yarn linear tensile material made of synthetic resin into the skin tissue has been used. This method has the additional effect of thickening the skin layer by forming collagen fibers and elastic fibers around the linear tensile material inserted into the skin, which can achieve a significant wrinkle removal effect compared to the past methods.

The linear tensile material used in such surgery is made of various forms and materials, and the representative one is a flexible cord form made of highly elastic organosiloxane polymer resin (Polyorganosiloxane). It is inserted into the inner layer of the skin through a hollow tubular needle called an injection needle, and then bound to body tissues such as the dermis or muscles to pull out the desired body parts. There is less after-feel and there is an advantage such that more natural molding is possible.

However, such a conventional linear tensile material has a problem that the lifting function is reduced or lost due to plastic deformation over time after surgery, due to the material properties of the organosiloxane polymer resin. In other words, the conventional organosiloxane polymer resin has an elastic strain of about 300%. If it is stretched more than that, plastic deformation occurs and the length is permanently increased, and tensile force continues to be applied for a long time even under a much smaller load. Permanent deformation occurs due to ground creep (creep) phenomenon, after a predetermined time elapses after the procedure, the procedure is unable to maintain the lifted position and fell, there is a problem that the wrinkle removal function is dropped or missing.

In addition, since the surface of the cord is smooth, parts other than the binding part have poor adhesion to body tissues, resulting in less effective surgical procedures, and uneven tension applied to the surgical parts, resulting in body deformation such as local depression. There was a high problem.

Meanwhile, another type of conventional linear tensile material is a yarn made of a synthetic resin material having a relatively low strain, such as polyester or polypropylene, which is used for a conventional suture, and one example thereof is illustrated in FIG. 1.

The linear tensile member 1A shown in FIG. 1 is formed so that a plurality of protrusions 2 are formed on the surface at predetermined intervals so as to increase the bondability with the body tissue. Such linear tensile member 1A is bound to the body tissue. As well as both ends are improved evenly bonded to the skin over the entire length, the treatment site can be pulled more uniformly, the quality of the treatment can be good.

However, this linear tensile member 1A is durable because the tensile strength of the product is significantly lower than that before the projection 2 is formed due to the difference in stress between the portions where the projections 2 are formed and the portions where the projections 2 are not formed. This is not good, and this also has a problem that plastic deformation occurs due to the creep phenomenon as a constant tensile load is applied, the treatment effect is lost in a relatively short time.

In addition, the elasticity is small, that is, because it is made of a relatively stiff material, it may give a foreign object when moving the skin tissue after the procedure, especially when the facial treatment is a high possibility of unnatural expression or movement .

In addition, the protrusions 2 formed on the surface may be accompanied by pain by stimulating the nerve tissue, there was also a problem that the protrusions 2 protrude out of the skin protruding.

The present invention is to solve the problems as described above, the object of the present invention is to prevent the permanent deformation due to excessive elongation and fatigue, etc., and other parts other than the binding portion is made uniformly good body tissue It is to provide a linear tensile material for plastic surgery.

The objects of the present invention are not limited to the above-mentioned objects, and other objects which are not mentioned will be clearly understood by those skilled in the art from the following description.

In order to achieve the above object, the present invention is installed in a state in which the tensile load to pull a predetermined portion inside the skin tissue of the body in a plastic surgery linear tensile material for stretching the wrinkles, comprising an organic siloxane polymer resin Core material in cord form made of flexible synthetic resin material; And it is coupled to surround the core material is stretched together with the core material, and provides a linear stretch material for a plastic surgery including a coating material made of a textile fabric structure woven a plurality of fiber yarns. The structure of the present invention increases the strength of the tensile load through the combination of the core material and the coating material, thereby preventing plastic deformation from occurring in the linear tensile material treated due to excessive elongation and load fatigue, and is performed between the fiber tissues forming the coating material. Allows cell tissues to grow, allowing uniform adhesion to body tissues.

In the linear tensile material for plastic surgery of the present invention, the core material may be made of any one of the mixed structure of the organosiloxane polymer resin, polyethylene resin and polypropylene resin, it is possible to further improve the tensile strength.

In some cases, the core material may also have a fiber fabric structure in which a plurality of fiber yarns are woven similarly or identically to the coating material. In this case, the binding of the linear tensile material to the body tissue of the procedure can be further improved.

The fiber yarn constituting the coating material may be made of any one of polyester fibers, polyethylene fibers, and polypropylene fibers used in conventional surgical sutures.

Preferably, the coating material is selected to have a strain less than the strain of the core material in consideration of the strain due to the tensile strength of the fiber yarn itself and the strain caused by the fiber weave structure as the elongation of the core is closer to the plastic deformation region. Through this, elongation of the core material is suppressed by the coating material before the plastic deformation occurs, it is possible to more effectively prevent the permanent deformation of the linear tensile material.

In addition, the fiber yarn constituting the coating material may be made of a porous fiber yarn formed with a plurality of fine grooves or micropores to further improve the bond between the linear tensile material and the body tissue.

Then, at least one end of the coating material may be provided with a finishing portion formed to be relatively thinner than other portions extending in the longitudinal direction longer than the core material. This finish allows for easier insertion of the linear tensile material into the surgical needle inserted into the skin tissue, which is removed after binding with the skin tissue.

Specific details of other embodiments are included in the detailed description and the drawings.

Advantages and features of the present invention and methods for achieving them will be apparent with reference to the embodiments described below in detail with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but may be embodied in various forms, and the present embodiments are merely provided to make the disclosure of the present invention complete and the general knowledge in the art to which the present invention belongs. It is provided to fully inform the person having the scope of the invention, the invention is defined only by the scope of the claims. Like reference numerals refer to like elements throughout.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 2 is a perspective view showing an embodiment of a linear surgical material for plastic surgery according to the present invention, Figure 3 is a cross-sectional view, as shown, the linear surgical material 100 for plastic surgery of the present invention is a cord made of a predetermined length It is made of a structure in which the covering member 110 is wrapped outside the core member 120 of the form.

The core material 120 is made of a highly flexible polymer resin material, it may be made of a synthetic resin material that is commonly used as a linear tensile material for wrinkle removal surgery, in particular dimethyl elasticity is excellent in elasticity, elasticity, durability and no objection to the human body It is preferably made of an organosiloxane poly (Polyorganosiloxane) material such as siloxane (Dimethylsiloxane), derivatives thereof and copolymers thereof.

The covering material 110 is to limit the elongation of the core material 120 within an appropriate limit, made of a textile fabric structure woven a plurality of fiber yarns 111, the core material 120 of its own by the fabric structure It is in close contact with the contracting force and stretches or contracts together with the core material 120 while maintaining the bonded state.

The fiber yarn 111 constituting the fibrous tissue of the coating material 110 is the same material as the commonly used surgical suture, for example, metal yarn such as gold, silver, nickel, polyester, capron, polypropylene, non It may be made of krill, polysorb material, or the like, and may be made of a single fiber or a variety of structures such as braided or braided with a plurality of fibers as in a conventional fiber yarn structure.

In addition, the fiber yarn 111 constituting the coating material 110 is preferably of a structure in which a fine groove or a fine hole of a predetermined depth is formed on the surface.

The fiber fabric structure of the coating material 110 is made by weaving various types of fiber yarns 111 in a variety of forms as described above, as shown in Figure 2 weaving the fiber yarns 111 in two orthogonal directions In addition to the structure, as shown in Figures A, B, and C of FIG. 4, respectively, a structure in which zigzag connects the fiber yarns 111 to form a mesh, each fiber yarn 111 is connected to each other while forming a spiral 111. Structure, each fiber yarn 111 may be made of a conventional weave structure of various types that can be stretched in the load direction, such as a structure connected to each other while being folded in a ring shape.

In addition, when the tensile force is applied, the elongation rate of the coating material 110 is determined by the strain rate according to the strain and the fabric structure of the fiber yarn 111 itself, the size and structure of the coating material 110 in consideration of this As the elongation of the core material 120 is closer to the plastic deformation region, the strain of the covering material 110 is smaller than that of the core material 120. This is to ensure that the core member 120 is stretched only within the deformation limit in which plastic deformation does not occur. For example, in the case of the core member 120 made of an organosiloxane polymer material as in this embodiment, about 300% or more When elongated to cause plastic deformation, less than about 300%, preferably considering the safety factor is easily deformed according to the elongation of the core material 120 until the length is increased to about 200%, if more than that, It is preferable to have a structure having a deformation strength of a degree that does not stretch even when a tensile force is applied to the (120).

An end portion of the covering member 110 extends in the longitudinal direction longer than the core member 120 to form a finish 101. The finishing portion 101 is contracted radially inward by its contracting force of the fiber fabric structure of the covering material 110 is formed relatively thinner than other parts.

The linear surgical material for plastic surgery of the present invention configured as described above is installed by pushing the inner portion of the surgical needle into the skin, which can be used according to a conventional lift surgery technique to evaluate the degree of deflection of the surgical part before surgery. Methods such as how to determine the desired shape in the procedure, how to determine the lift and binding points of the patient, and how to perform an incision after anesthesia and then using a needle, are common in the art. Any method known as may be employed without particular limitation. 5 shows an example used to remove wrinkles on the face as an example of the condition. As shown, one end of the linear tensile material 100 is bound and fixed to the support point 1, such as the muscles inside the body and the other end is bound to the point (2) to be lifted of the subcutaneous tissue and subjected to a tensile load Will lift the wealth.

The surgical linear tensile material 100 of the present invention is coupled to the outer surface of the core material 120, the support material 110 is coupled to support the tensile load complementarily, tensile strength compared to the linear tensile material made of conventional silicon cord only It is improved to prevent sagging of the treatment part due to plastic deformation of the core material 120. In addition, while the linear tensile member 100 is stretched within a predetermined limit, the fiber fabric structure of the cladding member 110 is unfolded while the binding force to the extension of the core member 120 is weakly applied, so that deformation is easily performed. It does not feel the foreign body as if using the conventional linear tensile material shown, it is possible to make a more natural shape of the treatment section. In addition, since the cellular tissue of the body enters and grows between the fiber structures constituting the coating material 110, the adhesion with the skin tissue is evenly improved, thereby preventing local deformation of the treatment part and evenly lifting the whole to improve the quality of the procedure. Can be.

At this time, as described above, the deformation rate of the covering member 110 is smaller than the core member 120 as the core member 120 approaches the yielding region, so that the covering member 110 is made of core material within the extent that the core member 120 is not plastically deformed. When elastically stretched together with 120, and the limit is more than the limit, the elongation of the core material 120 is suppressed by the covering material 110, thereby more effectively preventing permanent deformation.

In addition, since both ends of the covering member 110 are formed to have a relatively thin finishing portion 101, the structure can be easily inserted into the surgical needle, thereby improving usability.

Meanwhile, in the above-described embodiment, only the covering material 110 is exemplified as a fiber structure, but in some cases, the core material 120 may also have a fiber structure having higher elasticity and flexibility than the coating material 110. In this case, since tissue cells enter the core material portion 120 to improve the binding property, the quality of the procedure may be further increased.

In addition, when the fiber yarn 111 constituting the coating material 110 is made of porous fiber yarn as described above, since the procedure is made uniformly over a wider portion of the tissue cells, the binding between the linear tensile material and the skin tissue Can be further improved.

Although embodiments of the present invention have been described above with reference to the accompanying drawings, those skilled in the art to which the present invention pertains may implement the present invention in other specific forms without changing the technical spirit or essential features thereof. I can understand that. Therefore, the embodiments described above are to be understood in all respects as illustrative and not restrictive.

As described above, according to the present invention, by combining the coating material consisting of the fiber structure to the outside of the flexible core material, it is possible to prevent the plastic deformation of the core material by improving the tensile strength according to the composite structure and at the same time elastically within the plastic deformation limit The deformation can be made flexibly. Therefore, sagging of the procedure due to plastic deformation of the core material is prevented, and the procedure can be performed in a natural form without a sense of foreign matter, thereby increasing the satisfaction of the patient.

In addition, since the somatic tissue enters between the fibrous structure of the coating material and the bonding between the treatment part tissue and the tension member is made uniform and robust, the quality of the procedure can be further improved.

The durability and procedure quality improvement effect may be further enhanced by forming the core material into a fiber structure or by forming the coating material into a porous fiber.
