Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. Prior to this, terms or words used in the specification and claims should not be construed as having a conventional or dictionary meaning, and the inventors should properly explain the concept of terms in order to best explain their own invention. Based on the principle that can be defined, it should be interpreted as meaning and concept corresponding to the technical idea of the present invention. Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely examples of the present invention and are not intended to represent all of the technical ideas of the present invention, so that various equivalents And variations are possible.

1 is a perspective view showing a soft tissue repair mesh according to a first embodiment of the present invention, Figure 2 is an enlarged view showing the side of the mesh.

Referring to the drawings, the mesh 1 has a mesh shape and includes a mesh portion 10 formed long in the longitudinal direction thereof. Since the mesh part 10 includes a plurality of through holes 11, the mesh part 10 is most suitable for inducing adhesion with surrounding soft tissues. In other words, the surrounding soft tissues grow through the through holes 11 and are adhered to each other, whereby the mesh 1 can be fixedly integrated with the soft tissue, and the mesh 1 is integrated with the soft tissue, so it is touched or shown after the procedure. Don't.

The mesh 1 can be pulled after adhesion with the surrounding soft tissue, which will be described below. Since the mesh 1 does not have an anchor (means for fixing the mesh portion to the soft tissue), there is an advantage that the foreign matter after the procedure is small and can be removed if necessary.

It is preferable that the net form is made by knitting or weaving yarns of a predetermined material, and the plurality of through holes are spaces between yarns. The yarn may be made of polypropylene, PLA (poly lactic acid), or the like. The mesh portion 10 is made of such a polypropylene (polypropylene), PLA (poly lactic acid) is knitted or woven, so that a number of through holes 11 are formed well and the material is soft, for example, facial movements of the human body Can adapt well to muscle movement. The knitting may be made using a knitting machine disclosed in Republic of Korea Patent No. 10-0432398, Patent Publication No. 10-2006-0090871, Patent No. 10-0520003, etc., but is not necessarily limited to such a knitting machine.

The mesh portion 10 made of the polypropylene yarn is excellent in tension and is stabilized by being buried in the soft tissue without being decomposed or removed in the soft tissue even with time.

The mesh part 10 made of PLA has an advantage of being safe because it is decomposed and removed after 24 months after being implanted into soft tissue. As will be described later, the mesh unit 10 is inserted into the soft tissue and then fixed by pulling the soft tissue, but the pulled soft tissue is fixed to the pulled position even if the mesh unit 10 is later disassembled and removed, and thus treated. The effect can be maintained.

On the other hand, when the mesh portion 10 is knitted, as shown in FIG. 2, both sides 14 of the mesh portion 10 may be made into a smooth curved shape, for example, a loop shape. If both sides 14 are made in a smooth curved shape, it is possible to reduce or eliminate the occurrence of perforation, erosion, protrusion, foreign body, pain and the like of the skin.

The mesh portion 10 preferably has an elongation of 1% or more and 50% or less. If the elongation exceeds 50%, the mesh portion 10 is excessively stretched, which is disadvantageous for restoring the original. The elongation rate is obtained according to the DIN53504 regulation or according to the provisions of the Korean Pharmacopoeia. Since the mesh part 10 has the elongation rate, the problem of the conventional silicone implants, that is, the problem of breaking and disconnecting the silicone implants over time can be solved.

On the other hand, Figure 3 is a perspective view showing a mesh according to a second embodiment of the present invention.

The mesh 2 includes a mesh portion 10 and anchor portions 20 provided at both ends of the mesh portion 10.

The mesh unit 10 may be made of any one or a mixture thereof or a copolymer thereof selected from the group consisting of polypropylene, poly ε-caprolactone (PCL), polylactic acid (PLA), and poly vinyl alcohol (PVA). Can be. Since the structure of the mesh portion 10 is the same as that of the mesh portion 10 of the first embodiment, description thereof will be omitted.

The anchor portion 20 includes an anchor body 22 provided at both ends of the mesh portion 10 and a ring portion 24 formed on the anchor body 22.

When the anchor portion 20 is installed in the soft tissue, the ring portion 24 is inserted into and fixed to the soft tissue so that the anchor portion 20 may be fixed to the soft tissue. A plurality of rings 24 is formed at the end of the anchor body 22, it is preferable to be formed to be bent toward the mesh portion 10 to increase the fixing force.

The anchor portion 20 may be installed at both ends of the mesh portion 10, but may be installed at only one of the both ends. This anchor is disclosed in FIG. 4, which shows a mesh according to a third embodiment of the invention.

The mesh 3 includes a mesh portion 10 and an anchor portion 20 provided at one end of the mesh portion 10. The mesh portion 10 is the same as the mesh portion 10 of the second embodiment. In addition, the anchor portion 20 is the same as the anchor portion 20 of the second embodiment except that only one end of the mesh portion 10 is installed.

The anchor portion 20 is inserted into the soft tissue and then fixed to the soft tissue. After the fixing, the doctor pulls the other end of the mesh portion 10 (the side without the anchor portion 20) by a predetermined length to stretch the wrinkles or make the sagging tissue elastic, and then use a surgical suture (not shown in the drawing). Fix the mesh portion 10 to the soft tissue by using, and remove the remaining mesh portion 10 by cutting with scissors.

On the other hand, Figure 5 is a perspective view showing a mesh according to a fourth embodiment of the present invention.

The mesh 4 includes a mesh portion 10 and anchor portions 30 provided at both ends of the mesh portion 10. Since the mesh part 10 is the same as the mesh part 10 of the above-described embodiments, a description thereof will be omitted. In addition, the material of the anchor portion 30 may be the same as the material of the anchor portion 20 of the above-described embodiments.

The anchor portion 30 includes an anchor body 31 provided at both ends of the mesh portion 10 and a protrusion 32 formed to protrude upward from the anchor body 31. The projection 32 is preferably formed to be inclined toward the mesh portion 10 in order to increase the fixing force.

After the anchor part 30 is inserted into the soft tissue and the doctor presses the skin surface with the protrusion 32 facing upward (skin surface), the protrusion 32 is inserted into the soft tissue. 30) is fixed in the soft tissue.

Meanwhile, the through hole 34 may be formed in the anchor part 30 together with the protrusion 32. The through hole 34 may contact the mesh 4 for the purpose of transfer to protect the protrusion 32 from the surgical instrument (FIG. 6A) during the procedure and to securely implant the mesh 4 in a predetermined position. It plays a role to secure space and stable ligation.

In addition, the anchor portion 30 may be installed at both ends of the mesh portion 10, but may be installed only at either one of both ends. In this case, the side in which the anchor part 30 is installed is fixed by the anchor part 30, and the side in which the anchor part 30 is not installed is coupled to the soft tissue by using a surgical suture or the like.

6A-6C show surgical instruments for inserting mesh 1, 2, 3, 4 according to the invention into soft tissue.

The surgical instrument includes a rod member 110, an insertion tube 120 including a hollow portion 122 into which the rod member 110 can be inserted, and meshes 1, 2, 3, and 4. And a guide member 130 inserted into the hollow part 122.

The rod member 110 is tapered at one end so as to be easily inserted into the soft tissue, and has an elliptical cross section. Preferably, the rod member 110 has a width W of 1.2 cm to 1.5 cm, a thickness H of 2 mm to 4 mm, and a length of 25 cm to 30 cm.

Insertion tube 120 includes a hollow portion 122 that mates with the cross section so that the rod member 110 can be inserted. One end of the insertion tube 120 is preferably tapered sharply to be easily inserted into the soft tissue. Since the cross section of the rod member 110 is elliptical, the hollow portion 122 is formed elliptical. The term 'elliptic' means not only an ellipse in a mathematical sense, but also includes an ellipse in a mathematical sense. The hollow part 122 is formed along the longitudinal direction of the insertion tube 120 inside the insertion tube 120.

The guide member 130 inserts the meshes 1, 2, 3, and 4 into the hollow part 122 in a state in which the rod member 110 is removed from the hollow part 122. In more detail, when the insertion tube 120 is inserted into the soft tissue of the human body in a state where the rod member 110 is inserted into the hollow portion 122, the surrounding tissue is separated to form a space. Subsequently, the rod member 110 is removed from the hollow portion 122, and the mesh members 1, 2, 3, and 4 are inserted into the hollow portion 122 using the guide member 130, and then the guide member is removed. 130 is removed, and then the insertion tube 120 is pulled out. As the guide member 130, a wire having a predetermined length and thickness may be used.

On the other hand, Figure 7 shows the application of the mesh 1 to the face and neck, Figure 8 shows the application of the mesh 1 to the face, Figure 9 shows the application of the mesh 1 to the breast. 10 shows the application of the mesh 1 to the hips, and FIG. 11 shows the application of the mesh 1 to the abdomen. As shown in the figures is an example, the mesh may be used in various ways on various body parts as needed to smooth out (remove) or make the sagging or sagging areas elastic.

Next, a process of inserting the mesh 1 according to the first embodiment of the present invention into soft tissue using the surgical instrument will be described.

First, the portion to be inserted into the mesh 1 is cut by a predetermined length, and the insertion tube 120 is inserted into the cut portion while the rod member 110 is inserted into the hollow portion 122. Since the end of the rod member 110 is tapered sharply, the insertion tube 120 is inserted into the soft tissue of the human body, whereby the surrounding soft tissue is separated to form a space.

Subsequently, the rod member 110 is removed from the insertion tube 120, and the mesh 1 is inserted into the hollow part 122 using the guide member 130.

Next, after removing the guide member 130 from the insertion tube 120, the insertion tube 120 is removed from the soft tissue. When the guide member 130 and the insertion tube 120 is removed, only the mesh 1 is present in the soft tissue. When the time elapses in this state, for example, when about two weeks have elapsed, the soft tissue grows and is inserted into the through hole 11 of the mesh 1, whereby the surrounding soft tissue adheres. The mesh 1 is fixed to the soft tissue by the adhesion. After pulling out the mesh 1 in this state, the mesh 1 is sewn using a surgical suture for soft tissue or the like. The tug allows wrinkles to be removed or to make the sagging elastic. The force to pull the mesh 1 is evenly transmitted to the surrounding tissue by the adhesion so that natural molding can be achieved.

As such, the mesh 1 may be pulled after adhesion with the surrounding soft tissue occurs. Since the mesh 1 does not have an anchor, there is an advantage that the foreign matter after the procedure is small and can be removed if necessary. In addition, since it is integrated with the surrounding soft tissue, it is not touched or seen after the procedure.

On the other hand, the mesh (2) (3) (4) having the anchor portion 20, 30, the mesh (2) (3) (4) because the anchor portion (20) 30 can be fixed to the soft tissue Can be pulled directly after insertion into soft tissue. Thus, the meshes 2, 3 and 4 do not need re-treatment.
