Typically, the nose is raised in various kinds of nose surgery such as laryngectomy to raise nose, orthodontic correction (repair) to correct tip of nose, transthoracic graft to correct nose structure, and turbinate operation to relieve nasal symptoms Autologous cartilage is used as a pillar for giving or correcting.

Such nasal cosmetic surgery is performed by collecting the ear cartilage or by cutting a portion of the septum cartilage (hereinafter referred to as the nasal cartilage structure, see FIG. 9) to use the cartilage as a pillar. And the cartilage is dislocated from the original operation position after a long time after the operation. Especially, compared with Western people, Oriental people have a low nasal bridge, a small and weak cartilage making the nose, The amount that can be obtained for cartilage transplantation is limited, and there is a problem in that side effects after the surgery are liable to occur.

In addition, the use of autologous cartilage as described above requires procedures such as cartilage harvesting and nasal osteotomy, and additional operations such as anterior transplantation are necessary to correct the nasal bone and cartilage to the center. Therefore, And the operation cost is very expensive.

There is a method of using artificial materials as pillars in place of autologous cartilage in nose plastic surgery. Such artificial materials are generally known medical silicones (Dimethylsiloxane polymers), and in addition Gore-Tex, polyethylene Terephthalate (Polyethyleneterephthalate), and Proplast I and II (Medpore).

The artificial material (mainly silicone implant) has a variety of products ranging from thin plate type products of about 0.8 to 1.0 mm to thick block type products.

The insertion of such a plate-shaped implant to the tip of the nose to increase the nose is advantageous in that the artificial implant as a pillar has less room for warping or deformation compared to autograft. However, as an artificial implant, It is difficult to fix the prosthesis, and it requires special care while the implant is completely positioned after the operation, and it takes a long time.

Medical devices using biodegradable polymeric materials have been widely used in the medical field, and examples thereof include an absorbable suture, a bone cement for fracture treatment, a biological glue, a DDS (Drug Delivery System), and the like. (Bionix), BioScrew (Linvatec), etc. have been developed as a plate or screw of a plastic surgeon and a supplement has been developed in the field of facelift and browlift in the field of plastic surgery recently (Product name: Endotine, Coapt systems, Inc.). Biodegradable polymer materials require biodegradability and biocompatibility in order to be used for transplantation in the body. They must not show toxicity due to sterilization, operability and other degradation products. .

Therefore, many biodegradable polymeric materials satisfy the above conditions and are considered as a usable material. Among them, polylactic acid (PLLA), polyglycolic acid (PGA) and polylactic acid-polyglycolic acid copolymer (PLGA- BACKGROUND ART Polyhydroxy alcohols (PHA), polyhydroxybutyric acid (PHB), and polycaprolactones (PCL) have appropriate mechanical strength, biocompatibility, biodegradability and processability.

Generally, when polyglycolic acid (PGA) is used, it takes 3-6 months to decompose polylactic acid (PLLA) when mechanical strength is lost after 4-8 weeks, It should be made of suitable material.

The through hole 21 formed in the mesh 20 can be formed through post processing and the mesh 20 is formed and then passed through the through hole 21 by a machine such as a perforation device It is preferable that the shape of the through hole 21 is variously formed so as to improve the adhesion of the mesh 20 to the skin tissue. In addition, it is also possible to use a mold including up to the shape of the through-hole 21 to form it only by a molding process.

At this time, it is preferable that the distance between the through-hole 21 and the through-hole 21 in the mesh 20, that is, the diameter of the body, should not exceed 0.1 mm.

Although not shown in the drawing, the mesh 20 may include a straight edge portion (not shown) connecting four sides.

The support 10 and the mesh 20 may have various shapes such as a triangle, a rectangle, a square, or a streamlined shape elongated in the anteroposterior direction according to the shape, size, and surgical characteristic of the nose.

Also, the through-holes 21 of the mesh 20 may be formed to have various shapes according to the material of the mesh 20 to be used, a surgical purpose, etc. Preferably, the pair of bodies are mutually opposed A plurality of through holes 21 may be arranged in a zigzag structure along the longitudinal direction while the through holes 21 are formed in a similar 'rhombus' shape. That is, the through-hole 21 may be formed in a pseudo-honeycomb shape.

7, the mesh 20 includes a plurality of protrusions protruding from the outer circumferential surface of the body 20 or the support 10, or both of the protrusions protrude from the outer circumferential surface of the mesh 20 As shown in FIG.

First, as shown in Fig. 7A, the protruding portion is formed by a plurality of fixed or non-fixed shaped protrusions protruding in one direction or both sides of the longitudinal direction of the body, As shown in FIG.

The locking protrusions 22 may be formed to protrude in one direction or to protrude in one direction or to protrude in a forward direction and a backward direction so as to face each other in opposition to each other or to protrude in opposite directions symmetrical to each other, .

7, the protrusions may be formed of a plurality of protrusions 23 protruding outward from the outer circumferential surface of the body, and a plurality of protrusions (not shown) (Not shown) concaved inwardly from the outer circumferential surface of the body between the protrusions 23 and 23, and in some cases, the protrusions 23 and the recesses may be embodied as concavo-convex shapes have.

The protrusions 23 or protrusions formed in a concavo-convex shape may be manufactured by coating a mold release agent on the outer surface of the body 20 or the support 10 of the mesh 20, have.

Since the meshes 20 of the present invention are provided with various protrusions as described above, the contact area with the attached tissues increases, and in particular, when the meshes 20 are engaged, the body and the tissues are entangled with each other, Can be further improved.

Hereinafter, various forms of making a cored article according to the present invention will be described with reference to FIGS. 1 to 5. FIG.

First, as shown in FIGS. 1 and 3, the separable support 10 can be manufactured as a first embodiment of the present invention.

The separable support is constituted by a pair of supporting powders (10A, 10B) joined to each other while being in contact with each other,

The mesh 20 may be coupled between the pillars 11 of the supporting powders 10A and 10B.

That is, as described above, since the mesh 20 is coupled to the column of the support table 10, the size of the nose molding is small (generally about 2 * 1 cm in length and width) The coupling operation of the mesh 20 and the support base 10 may be difficult,

It is advantageous that the support member 10 is made of a pair of supporting powders 10A and 10B and the meshes 20 are superimposed therebetween and then joined and fixed.

In addition, as shown in the drawing, the separable support is not limited to a form in which the support powders 10A and 10B are completely separated from each other, but the support posts 10A and 10B, 11a in a manner that they are widened to both sides.

The hinge coupling method through the front columnar portion 11a of the support powder 10A and 10B can be implemented in various assembled forms. Since this configuration is not related to the essential features of the present invention, a detailed description thereof will be omitted .

It is possible to more easily insert and fix a single mesh 20 between the supporting powders 10A and 10B when the supporting powders 10A and 10B having the hinge-joining structure are introduced.

Further, as shown in FIG. 2, as a second embodiment of the present invention, the present invention can be realized only with the mesh 20 'having the leg portions 14A', 14B '.

That is, in the second embodiment of the present invention, the support base 10 on which the mesh 20 'is supported is not provided, and the support base 10 is folded and extended in both lateral directions at the rear end so as to form a fixing groove 15 therebetween May be embodied as a mesh 20 'comprising a pair of legs 14A', 14B '.

Therefore, when the nose of the present invention is formed only of the mesh 20 ', the rim of the mesh 20' functions as the pillar 11a to 11c of the support 10 described above. More specifically, The end portion 20'a of the body, which forms part of the through-hole 21'a formed in the rim of the outer rim 21 ', functions as the pillar.

In addition, the through holes 21 'formed in the rim and open outward function to partially fix the tissues or muscles when the nose is inserted and fix the end portions 20'a of the body forming the rim, So that the mesh 20 'can be more firmly fixed.

Since the leg portions 14A 'and 14B' are integrally formed with the mesh 20 'as shown in [A] of FIG. 2, the through holes formed in the leg portions 14A' and 14B ' The first and second suture holes 21 'function as the first suture holes 16 and are inserted into tissues or muscles in the openings 14a formed between the rear ends of the legs 14A' and 14B ' .

Meanwhile, as shown in [B] of FIG. 2, the leg portions 14A 'and 14B' may be further combined with the body of the mesh 20 'through an injection molding method or the like, The leg portions 14A 'and 14B' may be provided with the first suture holes 16 separately.

In this case, a method in which the first suture hole 16 is realized by closing the opening 14a (see [A] in Fig.

In addition, other detailed configurations and effects of the mesh 20 'are greatly different from those of the first embodiment described above, and therefore, detailed description thereof will be omitted.

 4 and 5, as a modification of the first embodiment of the present invention, an integral support is introduced, and the mesh 20 is supported on one side or both sides of the posts 11 of the support base 10 As shown in FIG.

In other words, in the case of the integral support in the case of the separate support according to the first embodiment, the coupling operation of the mesh 20 is somewhat difficult. On the other hand, when the single mesh 20 is biased on either side Mesh 20 can be coupled to both sides of the support frame 10 in a balanced manner so that the mesh 20 can be attached at various positions according to the shape of the nose, The bonding force through the adhesion can be realized in various forms.

As described above, when the mesh 20 is made of a biodegradable polymer material, the mesh 20 is disassembled and absorbed by the separable support so that a gap is generated between the supporting powders 10A and 10B, When the integrated support is introduced, the mesh 20 attached to both outer sides of the support 10 is disassembled and absorbed so that the tissue is naturally tied to the support 10 The pillar portions 11 of the pillar-shaped member 11 can be adhered.

Particularly, when the integrated support is introduced, the thickness of the mesh 20 and the longevity of the mesh 20 (in some cases, a plurality of meshes 20 can be coupled to one or both sides) Nasal implants can be manufactured.

As shown in FIG. 8, as another modified example of the first embodiment of the present invention, it is possible to fabricate a nasal implant of the integral structure of the mesh 20 and the support 10.

The mesh 20 and the support 10 are made of the same material in the case of the integrated structure of the mesh 20 and the support frame 10 and therefore the mesh 20 is formed at the same time as the support frame 10 by injection molding It is advantageous from the viewpoint of simplification of the manufacturing process,

Also, since the body of the mesh 20 corresponds to the thickness of the column of the support 10, it may be more advantageous to increase the bearing capacity of the nasal implant.

The present invention is based on the above-described various embodiments, and an optimized nasal prosthesis that does not cause side effects is selected by taking into account the nasal shape, size, and purpose of surgery (cosmetic purpose or therapeutic purpose) It is versatile and useful because it can be used.

While the present invention has been described with reference to the accompanying drawings, it is to be understood that the present invention is not limited thereto. Various modifications, alterations, and changes may be made by those skilled in the art. And substitutions are to be construed as falling within the scope of protection of the present invention.
