[0067] Figure 1 is a perspective view showing a mesh member according to one embodiment of the present invention, Figure 2 is a perspective view showing a mesh assembly in which an inserter is connected to a mesh member according to one embodiment of the present invention.

[0068] Reference Figure 1 and Figure 2 , a mesh assembly 40 according to one embodiment of the present invention may include a mesh member 100 and an inserter 400 .

[0069] The inserter 400 may be an insertion tube such as a cannula or a needle, and the mesh member 100 may be combined with the insertion tube to form the mesh assembly 40. Figure 1 and Figure 2 , the mesh member 100 is shown inserted into the inserter 400. However, in another example, a lifting thread having barbs (cogs) (protrusions) may be inserted, and the material inserted into the inserter 400 is not limited to these examples. The mesh member 100 may be inserted into human skin tissue through an insertion tube such as a trocar.

[0070] Reference Figure 1 The mesh member 100 may include a plurality of wire members 110 and may be formed into a cylindrical shape. Holes may be provided between the plurality of wire members 110. The plurality of wire members 110 may extend in a spiral shape along the length direction of the mesh member 100. The plurality of wire members 110 may cross and intertwine with each other to form a three-dimensional cylindrical shape.

[0071] The inner side of the mesh member 100 may be formed with a channel having a predetermined diameter, thereby being configured into a three-dimensional shape similar to a cylinder. The channel having a predetermined diameter formed on the inner side of the mesh member 100 may be hollow, but is not limited thereto. For example, a core or the like may be provided on the inner side of the mesh member 100.

[0072] The mesh member 100 may be made of a medical material for human body implantation or insertion, for example, a nonabsorbable polymer or a biodegradable polymer that is harmless to the human body and has biocompatibility.

[0073] The biocompatible mesh member 100 can be made of a material selected from polyesters, polyhydroxyalkanoates (PHAs), poly(α-hydroxy acid), poly(β-hydroxy acid), poly(3-hydroxybutyrate-co-valerate) copolymer (PHBV), poly(3-hydroxypropionate) (PHP), poly(3-hydroxyhexanoate) (PHH), poly(4-hydroxy acid), poly(4-hydroxybutyrate), poly(4-hydroxyvalerate), poly(4-hydroxyhexanoate), poly(esteramide), polycaprolactone, polylactide, polyglycolide, poly(lactide-co-glycolide) copolymer (PLGA), polydioxanone, polyorthoesters, polyetheresters, polyanhydrides, poly(glycolic acid-co-trimethylene carbonate) copolymer, poly Phosphate esters, polyphosphate-polyurethanes, poly(amino acids), polycyanoacrylates, poly(trimethylene carbonate), poly(imino carbonate), poly(tyrosine carbonate), polycarbonates, poly(tyrosine arylates), polyalkylene oxalates, polyphosphazenes, PHA-PEG, ethylene-vinyl alcohol copolymers (EVOH), polyurethanes, silicones, polyesters, polyolefins, polyisobutylene and ethylene-α-olefin copolymers, styrene-isobutylene-styrene triblock copolymers, acrylic polymers and copolymers, vinyl halide polymers and copolymers, polyvinyl chloride, polyvinyl ether, polyvinyl methyl ether, polyvinylidene halide, polyvinylidene fluoride, polyvinylidene chloride, polyfluoroolefins, polyperfluoroolefins, polyacrylonitrile, polyvinyl ketone, polyvinyl aromatic hydrocarbons (polyvinyl chloride), aromatics), polystyrene, polyvinyl ester, polyvinyl acetate, ethylene-methyl methacrylate copolymer, acrylonitrile-styrene copolymer, ABS resin and ethylene-vinyl acetate copolymer, polyamide, alkyd resin, polyoxymethylene, polyimide, polyether, polyacrylate, polymethacrylate, polyacrylic acid-co-maleic acid, chitosan, dextran, cellulose, heparin, hyaluronic acid, alginate, inulin, starch or glycogen, chitosan, dextran, cellulose, heparin, hyaluronic acid, alginate, inulin, starch or glycogen.

[0074] Furthermore, the mesh member 100 may be formed from a hydrolyzable material. For example, the mesh member 100 may be formed from a material containing polydioxanone (PDO). Alternatively, the mesh member 100 may be formed from a material containing one or more polymers selected from the group consisting of polylactic acid (PLA), poly-L-lactide (PLLA), polycaprolactone (PCL), polyhydroxyalkanoate (PHA), polyhydroxybutyrate (PHB), poly-D-lactide (poly-D-lactide), and poly-DL-lactide (PDLLA).

[0075] When the mesh member 100 is inserted into the skin, the skin tissue easily penetrates into the interior of the mesh member 100. Therefore, the bonding of the mesh member 100 and the skin tissue can be promoted.

[0076] In addition, the mesh member 100 may include a core 200 and cogs 250 protruding from a surface of the core 200 .

[0077] The core 200 may be located inside the mesh member 100. For example, the core 200 may be disposed in a channel inside the mesh member 100 and extend along the length of the mesh member 100. The diameter of the core 200 may be smaller than the diameter of the channel. The cross-section of the core 200 may be circular, but is not limited thereto. The cross-section of the core 200 may be various shapes, such as an elliptical or polygonal shape.

[0078] The barbs 250 may be provided to protrude from the surface of the core 200. The barbs 250 may be provided to extend from the surface of the core 200 at least one.

[0079] The barbs 250 may protrude from the surface of the core 200 in a direction inclined toward one side. The barbs 250 may be formed to have a length such that the ends thereof extend to the outside of the mesh member 100. That is, the ends of the barbs 250 may protrude to the outside of the mesh member 100 through the holes 120 between the plurality of wire members 110 included in the mesh member 100.

[0080] The plurality of barbs 250 may be formed on the upper and lower portions of the core 200. Specifically, the plurality of barbs 250 may be formed alternately at 180-degree intervals on the outer circumference of the core 200. However, the positions of the barbs 250 are not limited to this embodiment. For example, the barbs 250 may be formed alternately at various intervals, such as 90-degree intervals or 120-degree intervals, on the outer circumference of the core 200.

[0081] Reference Figure 1According to the cross section of mesh member 100, the outer diameter L1 of the cylindrical mesh of mesh member 100 may be determined by the area formed by the plurality of wire members 110 forming pores 120. In addition, the length L2 of the mesh member 100 in the direction in which the barbs extend may be determined by the barbs 250 protruding from core 200.

[0082] Therefore, the shape of the insertion tube for accommodating the mesh member 100 should have a shape corresponding to the extended length L2 of the mesh member 100 so that the insertion tube can be easily combined with the mesh member 100. In addition, if the material of the barbs 250 is hard or thick, the inner diameter of the insertion tube having a circular cross-section should be larger than the length L2 in the direction in which the barbs of the mesh member 100 extend. If the inner diameter of the insertion tube having a circular cross-section is smaller than the length L2 in the direction in which the barbs of the mesh member 100 extend, it is difficult to insert the mesh member 100 into the insertion tube.

[0083] According to one embodiment of the present invention, a core 200 is formed inside the mesh member 100 , and barbs 250 protruding from the surface of the core 200 are provided, thereby improving the fixing force and traction force of the mesh member 100 on the skin tissue.

[0084] Reference Figure 2 , the mesh assembly 40 according to one embodiment of the present invention may include a mesh member 100 and an inserter 400. The mesh member 100 is as described above. Figure 1 As stated.

[0085] Assuming that the direction in which the core 200 extends is a first direction, the inserter 400 may extend along the first direction. A connection port 500 may be provided at the rear end portion of the inserter 400 for ease of use.

[0086] The inserter 400 may have a tubular passageway formed therein. The mesh member 100 may be disposed within the passageway. The connection port 500 may also have holes formed therein and communicate with the passageway. The mesh member 100 may pass through the holes of the connection port 500 and the passageway and be disposed at the front end of the inserter 400.

[0087] In the present disclosure, the inserter 400 may include a cannula, a Stewart needle, a skin needle, a catheter needle, an injection needle, etc., which may be a term including any type of medical device having a channel space inside.

[0088] In this way, the mesh component 40 according to the present invention can improve the fixing force and traction force on biological tissues, and has excellent adhesion, retention and fixing effects on skin tissues.

[0089] Figure 3 and Figure 4 FIG2 is a diagram exemplarily showing an inserter that can be applied to the mesh assembly according to the present invention.

[0090] In order to avoid duplication and facilitate explanation, the following Figure 1 and Figure 2 right Figure 3 and Figure 4 Provide explanation.

[0091] Reference Figure 3 and Figure 4 The inserter 400A may include an insertion tube body 410 , a channel space 420 , a rear end opening portion 430 , a front end portion 412 , and a front end opening portion 440 .

[0092] The rear end opening portion 430 may be provided at the rear end portion of the insertion tube body 410. The insertion tube is formed with a passage space 420 communicating with the rear end opening portion 430.

[0093] The front end portion 412 may be provided at the front end portion of the insertion tube body 410. A front end opening portion 440 may be provided in the front end portion 412. The front end opening portion 440 may communicate with the channel space 420.

[0094] The inserter 400A may include a compression portion 450. Here, the term compression portion 450 is used only to describe the shape of the inserter 400A and is not limited to the compression portion 450 being formed by compressing the inserter body 410. For example, the inserter 400A may be manufactured using a mold for manufacturing a tube shape having an elliptical cross-section.

[0095] Therefore, in the inserter 400A according to one embodiment of the present invention, the mesh member 100 may be provided in the rear end opening portion 430 , the channel space 420 , and the front end opening portion 440 .

[0096] The inserter 400A according to one embodiment of the present invention can be configured to change the shape of the insertion tube body 410 by the compression portion 450 so that its shape corresponds to the shape of the mesh member 100, i.e., the material inserted into the patient's skin, thereby having advantages in terms of surgical convenience and postoperative recovery.

[0097] Figure 5 and Figure 6 FIG. 1 is a diagram exemplarily showing another inserter that can be applied to the mesh assembly according to the present invention.

[0098] In order to avoid duplication and facilitate explanation, the following Figures 1 to 4 right Figure 5 and Figure 6 Provide explanation.

[0099] Reference Figure 5 and Figure 6 In an inserter 400B according to another embodiment of the present invention, the compressed portion 450 may be formed over most of the insertion tube body 410, and the compressed portion 450 may extend to the front end opening 440. In this embodiment, in the inserter 400B, the rear end portion of the insertion tube body 410 remains uncompressed, but in other embodiments, the compressed portion 450 may be formed over the entire insertion tube body 410, including the rear end portion of the body 410.

[0100] In this way, the inserter 400B according to another embodiment of the present invention can be configured to change the shape of the insertion tube body 410 through the compression portion 450 so that its shape corresponds to the shape of the mesh member 100, i.e., the material inserted into the patient's skin, thereby having advantages in surgical convenience and postoperative recovery.

[0101] Figure 7 and Figure 8 FIG. 1 is a diagram exemplarily showing still another inserter applicable to the mesh assembly according to the present invention.

[0102] In order to avoid duplication and facilitate explanation, the following Figures 1 to 4 right Figure 7 and Figure 8 Provide explanation.

[0103] Reference Figure 7 and Figure 8 In an inserter 400C according to another embodiment of the present invention, the front end portion 414 of the insertion tube body 410 is formed into a shape having a cut surface, and the front end opening 440 of the passage space 420 is formed on the cut surface of the front end portion 414. This structure has the advantage that the compressed portion 450 can extend to the front end portion 414.

[0104] Thus, the inserter 400C according to another embodiment of the present invention can be configured to change the shape of the insertion tube body 410 by the compression portion 450 so that its shape corresponds to the shape of the material inserted into the patient's skin, thereby having advantages in terms of surgical convenience and postoperative recovery.

[0105] Figure 9 is a perspective view of an inserter according to one embodiment of the present invention.

[0106] In order to avoid duplication and facilitate explanation, the following Figures 1 to 8 right Figure 9 Provide explanation.

[0107] Reference Figure 9 , the inserter 600 may include an insertion tube 605 , a connecting portion 610 and a front end portion 614 .

[0108] The connection portion 610 may be connected to the rear end of the insertion tube 605. The rear end of the connection portion 610 may be provided with a hole-shaped rear end opening portion 630. The rear end opening portion 630 may communicate with a channel space 620 to be described later.

[0109] The front end portion 614 may be connected to the front end of the insertion tube 605. The front end portion 614 may be provided with a hole-shaped front end opening portion 640. The front end opening portion 640 may communicate with a channel space 620 to be described later.

[0110] The mesh member 100 may be disposed in the rear end opening portion 630 , the channel space 620 , and the front end opening portion 640 .

[0111] The insertion tube 605 may include a frame portion 650 , a compression portion 670 , and a channel space 620 .

[0112] The insertion tube 605 may include a hole-shaped channel space 620 surrounded by a frame portion 650. The insertion tube 605 may be any one of a cannula, a Stewart needle, a skin needle, a catheter needle, and an injection needle.

[0113] The frame portion 650 may extend in a first direction Z. The first direction Z may extend in a length direction of the frame portion 650. The second direction Y or the third direction X may be a direction crossing the first direction Z.

[0114] The frame portion 650 may include a long-axis frame 651 disposed along the second direction Y and a short-axis frame 656 disposed along the third direction X. The long-axis frame 651 and the short-axis frame 656 may be integrally formed. In other words, the end of the long-axis frame 651 may be connected to the short-axis frame 656 to form the frame portion 650.

[0115] In the inserter 600 according to this embodiment, the frame portion 650 can be provided in an elliptical shape. The short-axis frame 656 can be provided in a curved shape having a curvature smaller than that of the long-axis frame 651. Furthermore, the channel space 620 can be formed in the elliptical space formed by the inner side surfaces of the long-axis frame 651 and the short-axis frame 656.

[0116] The channel space 620 can be controlled by a compression portion 670 provided on the frame portion 650. The compression portion 670 refers to a portion of the frame (the portion including a location (point) where the frame is compressed by applying pressure). For example, when the compression portion 670 is formed on the long-axis frame 651, the frame portion 650 can be formed into an elliptical shape. As a result, the length L4 of the long-axis frame 651 formed along the second direction Y in the frame portion 650 can be increased, and the length L3 of the short-axis frame 656 formed along the third direction X can be reduced.

[0117] In other words, the width of the passage space 620 formed along the third direction X may be reduced according to the length L3 of the minor axis frame 656 , and the width of the passage space 620 formed along the second direction Y may be increased according to the length L4 of the major axis frame 651 .

[0118] For the sake of explanation, refer again to Figure 1 If the channel space 620 of the inserter 600 maintains a circular cross-section and has an increased inner diameter to accommodate the mesh member 100 and the barbs 250, the overall diameter of the inserter 600 may become too large. In this case, an enlarged hole may be formed at the surgical site of the patient, which may increase the possibility of scarring.

[0119] Therefore, according to an embodiment of the present invention, an inserter can be provided in which the shape of the inserter 600 is changed into an elliptical shape so as to have a deformed shape corresponding to the shape of the mesh member 100. That is, an inserter can be provided in which the length L4 of the long-axis frame 651 is increased and the length L3 of the short-axis frame 656 is decreased so as to have a deformed shape corresponding to the shape of the mesh member 100 provided with the barbs 250.

[0120] Specifically, the inserter 600 according to the embodiment of the present invention satisfies the following relationship.

[0121] a=L2 / L1,b=L4 / L3,a and b satisfy 0.5≤b / a≤2.

[0122] Wherein, L1 is the outer diameter of the cylindrical mesh of the mesh member 100, and L2 is the length in the direction in which the barbs of the mesh member 100 extend (refer to Figure 1 ).
