Description

Tow-way spinous polydioxanone suture < RTI ID = 0.0 >

The present invention relates to a bi-directional visible suture.

The skin of a person is gradually aging as it passes the age of 20, and the speed gradually increases around 25 years old. There are various symptoms of skin aging that you can feel like dryness, dryness, etc. It is typical that the skin loses its elasticity and has fine lines.

Such a method of improving skin aging is a lift procedure. Lift surgery is performed by inserting a medical suture that is safe to the body in a certain direction to subcutaneously adhere to subcutaneous tissues and dermis tissues to stimulate cellular tissue regeneration and stimulate collagen production to obtain skin elasticity improvement effect.

However, the end of the thread inserted into the subcutaneous layer was not firmly fixed to the subcutaneous layer, and the skin pulling performance was deteriorated. In addition, since the contact area between the thread and the subcutaneous layer was not maximized, the collagen activity was not smooth.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily carry out the present invention. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Like parts are designated with like reference numerals throughout the specification.

A bi-directional visible suture according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2. FIG.

FIG. 1 is a front view showing a bi-directional visible suture according to an embodiment of the present invention, and FIG. 2 is an enlarged view of a portion A shown in FIG.

Referring to FIGS. 1 and 2, the bi-directional suture 100 according to the present embodiment includes a main body 110, a first barb 120, and a second barb 130).

The bidirectional viscous suture 100 according to the present embodiment may be made of polydioxanone (PDO), polypropylene (PP), poly-capcolactone (PCL), polylactic acid (PLA) -Lactic-Co-Glycolic) chitosan, and combinations thereof. That is, the bi-directional visible suture 100 can be made of a material which is excellent in biodegradability and harmless to the body.

Polydioxanone is a body absorbable suture widely used in surgical operations. Polydioxanone has little or no side effects due to foreign substances because it dissolves in the body with almost no allergies or side effects.

Polyglycolide is the most representative biodegradable synthetic polymer synthesized by polycondensation of glycolic acid or ring-opening polymerization of glycolide.

Chitosan is a natural high molecular substance produced by biosynthesis of organisms such as shrimp and crabs. Chitosan can exhibit excellent biocompatibility in tissues such as humans, animals, plants, and the body. Chitosan is easily biodegradable, environmentally friendly, and has little toxicity. In addition, chitosan is excellent in formability such as powder, fiber, membrane, sponge, and has functionality such as viscosity, moisturizing property, metal adsorption property, antibacterial activity and antifungal activity.

The main body 110 is formed to have a length of about 35 mm to 200 mm, and the length of the main body 110 can be changed according to the treatment site.

The diameter of the main body 110 is 0.04 mm to 0.4 mm. If the diameter of the main body 110 is 0.04 mm or less, it easily breaks. If the diameter exceeds 0.4 mm, the treated region may become unnatural and difficult to perform.

The first barb 120 and the second barb 130 are attached to the body tissues and include hooking branches 121 and 131.

The latching branches 121 and 131 are formed by cutting at least a part of the main body 110 in a staggered form. However, the latching branches 121 and 131 may be formed by attaching the main body 110 to the surface of the main body 110 without being cut.

The hooking branches 121 and 131 are lifted from the main body 110 at a predetermined angle. Spaces 122 and 132 are formed between the main body 110 and the engaging branches 121 and 131 while the engaging branches 121 and 131 are lifted at a predetermined angle. When a bi-directional suture is inserted into the body tissue, body tissue may enter the space 112, 132. As the body tissues are introduced into the spaces 112 and 132, the latching branches 121 and 131 are caught by the body tissues.

In order to stably fix the hooking branches 121 and 131 with the body tissue, the hooking branch 121 of the first barb 120 and the hooking branch 131 of the second barb 130 are connected to each other It is inclined in the opposite direction. In other words, the latching branch 121 of the first barb 120 is formed by cutting the main body 110 in one direction, and the latching branch 131 of the second barb 130 is formed so that the main body 110 is bent in the other direction It is formed as an incision.

The first barb 120 and the second barb 130 formed by arranging the hooking branches 121 and 131 constitute one unit L. [ The length of the unit body L is about 10 mm to 35 mm, and a plurality of unit pieces L are formed along the length direction of the body 110. One unit is closely formed with respect to the main body 110 having a predetermined length. The intervals of the neighboring unit bodies L are equal to the spacing of the adjacent hooking branches 121 and 131.

In addition, when the length of the unit body is 10 mm or less, the unit pieces are closely formed with respect to the entire length of the body 110, so that the fixing force of the bi-directional visible suture can be reduced. If the length of the unit is more than 35 mm, the number of the unit pieces is insufficient relative to the overall length of the body 110, so that the fixing force can not be improved.

  The bi-directional visible suture 100 scatters the skin dermal layer (body tissue) with a needle and then inserts it into the subcutaneous or muscle layer adjacent to the subcutaneous layer. At this time, the hooks 121 and 131 of the first barb 120 and the second barb 130 are fixed to the body tissue. The body tissues can be introduced into the spaces 122 and 132 generated when the latching branches 121 and 131 are lifted from the main body 110. Whereby the bi-directional suture 100 can be securely fixed within the body tissue. The first barb 120 and the second barb 130 facing each other in a different direction are formed of unit pieces, and the unit pieces are respectively fixed to the body tissue. The body 110 can be fixed to the body tissue by intervals according to the unit. Accordingly, even if the body tissue inserted with the bi-directional visible suture 100 moves, the body 110 will not be loosened in the body tissue.

In addition, since the unit pieces are fixed to the body tissues, it is possible to prevent the side effect that the bi-directional visible suture protrudes from the body insertion portion because the skin is cried or the fixing force is released in the skin tissue due to the improved fixation force.

In addition, since the unit pieces are fixed to the body tissues, the lifting force can be dispersed. This allows the lifting to be carried out evenly with a uniform overall force.

Around the bi-directional suture (100) firmly fixed to the body tissue by the units, collagen and other proteins necessary for skin regeneration are synthesized and pulled around the tissue. On the other hand, since the contact area between the bidirectional visor suture 100 and the body tissue is increased by the body tissue inserted into the spaces 122 and 132, protein production required for skin regeneration can be improved.

The newly regenerated dermis tissue around the bi-directional visible suture 100 can grow into skin tissue that can improve elasticity, whitening, wrinkles and the like compared to the previous tissue.

Yet another embodiment of the present invention has most of the components of the embodiment described with reference to Figs. Referring to FIG. 3, the main body 110 according to the present embodiment is divided into a first region 110a and a second region 110b. In the first region 110a, a first barb 120 and a second barb And two barbs 130 are arranged in the unit body L. In the second region 110b, a unidirectional barb 160 is formed along the longitudinal direction. The inclination of the unidirectional barb 160 is formed to be the same as the inclination of the second barb 130. However, it may be formed to be the same as the inclination of the first barb 120. When the suture 200 is inserted into the body tissue, the first region 110a is located in the tissue deep in the inserted direction and the second region 110b is located in the tissue surrounding the inserted direction inlet. The unit members L are fixed to the body tissue deep in the inserted direction and the fastening force of the suture 200 can be further increased as the unidirectional barbs 160 are fixed to the body tissue around the entrance. In other respects, the configuration of the embodiment of FIGS. 1 and 2 can be applied as it is.

Other embodiments of the present invention have most of the components of the embodiment described with reference to Figs. 4, the unit body made of the first barb 120 and the second barb 130 is disposed along the circumferential direction of the main body 110. The bi- Lt; / RTI > Arranged intervals are arranged at equal intervals. 3, the number of the unit pieces arranged along the circumferential direction of the main body 110 can be increased by reducing the arrangement interval.

The hooks 121 and 131 of the first barb 120 and the second barb 130 and the hooks 121a and 131a of the first barb 120a and the second barb 130a, Are formed in a zigzag shape. However, the latching branches 121, 131, 121a, 131a may be symmetrically formed on the same line. In other respects, the configuration of the embodiment of Figs. 1 and 3 can be applied as it is.

The remaining branches (140, 150) are formed along the longitudinal direction of the latching branches (121, 131). The branches 140 and 150 are formed by cutting at least a part of the latching branches 121 and 131 in a staggered form. In this case, the remaining spaces 141 and 151 are formed between adjacent ones of the adjacent ones 140 and 150.

The fixing force of the bi-directional suture 100 can be improved while the body tissues are inserted into the latching branches 121 and 131, the spaces 122 and 132, the limbs 140 and 150, and the rest spaces 141 and 151. In addition, the contact area between the body tissue and the bidirectional viscous suture 100 is improved, and protein production required for skin regeneration can be improved.
