The present invention relates to a linear tension material for surgery used to pull skin tissue. An object of the present invention is to provide a linear tension material for plastic surgery which prevents permanent deformation due to excessive elongation and fatigue and of which a portion besides united portions is uniformly and properly united with body tissue. According to an aspect of the present invention, there is provided a linear tension material for plastic surgery which is provided to pull a predetermined site inside skin tissue of the body in a state of tensile load so as to smooth out wrinkles and pull the tissue to tighten a saggy portion, the linear tension material including: a core material in a code shape, which is made of a flexible resin including polyorganosiloxane; and a covering material which covers an outside of the core material to be united with the core material, shrinks together with the core material, and has a fiber textile structure formed by weaving a number of fiber threads. |

| Claim: |
1. A linear tension material for plastic surgery which is provided to pull a predetermined site inside skin tissue of the body in a state of tensile load so as to smooth out wrinkles and pull the skin tissue to tighten a saggy portion of the skin, the linear tension material comprising: a core material in a code shape, which is made of a flexible resin including polyorganosiloxane; and a covering material which covers an outside of the core material to be united with the core material, shrinks together with the core material, and has a fiber textile structure formed by weaving a number of fiber threads. |
| Claim: |
2. The linear tension material of claim 1, wherein the core material has a combined structure having one from among polyorganosiloxane, polyethylene resin, and polypropylene resin. |
| Claim: |
3. The linear tension material of claim 1, wherein the core material has a fiber textile structure formed by weaving a number of fiber threads. |
| Claim: |
4. The linear tension material of claim 1, wherein the fiber textile structure is one of a structure in which fiber threads are weaved in two orthogonal directions, a structure in which the fiber threads are connected in zigzags in a net pattern, a structure in which the fiber threads are connected in a spiral shape, and a structure in which the fiber threads are connected to each other while overlap in a hook shape. |
| Claim: |
5. The linear tension material of any one of claims 1 to 4, wherein the covering material has strain smaller than strain of the core material as an elongation rate of the core material approaches to a plastic deformation region so that elongation stress of the core material is maintained at a degree within a plastic deformation limit and pulling force is maintained. |
| Claim: |
6. The linear tension material of any one of claims 1 to 4, wherein the fiber threads of the covering material are made of one of polyester fibers, polyethylene fibers, and polypropylene fibers used for a conventional suture for surgery. |
| Claim: |
7. The linear tension material of any one of claims 1 to 4, wherein the fiber threads of the covering material include porous fiber threads having a number of fine notches or fine holes. |
| Claim: |
8. The linear tension material of any one of claims 1 to 4, wherein at least an end portion of the covering material includes a closure portion which externally extends in a longitudinal direction to be longer than the core material and is formed to be relatively thinner than other portions. |
| Claim: |
9. The linear tension material of any one of claims 1 to 4, wherein the fiber thread that forms the covering material is a fiber thread having a surface treated to be smooth. |
