Filler for removing wrinkles

Abstract

The present invention relates to a filler for removing wrinkles, which comprises: a thin and long tubular main body to be placed so as to penetrate through subcutaneous tissue; and through-holes for guiding tissue cells surrounding the main body into the main body, so as to form fibrous tissue, wherein the through-holes are formed so as to communicate with a hollow portion formed in said main body in the lengthwise direction from the outer surface of said main body. The filler for removing wrinkles according to the present invention is prevented from being deformed or moved by pressure on the skin or by an external force arising after being inserted into the subcutaneous tissue, and can be applied to various body parts having wrinkles, including deep wrinkles. Furthermore, the wrinkle-removing effects of the filler of the present invention may last (semi)permanently.

1 . A filler for removing wrinkles, comprising:
 a thin and long tubular main body provided so as to penetrate the subcutaneous layer; and   through-holes provided so as to guide tissue cells surrounding the main body into the main body to form fibrous tissue, wherein the through-holes are formed to communicate with a hollow portion formed in the main body in a lengthwise direction from the outer surface of the main body.   
     
     
         2 . The filler for removing wrinkles according to  claim 1 , wherein the main body is formed integrally and has a circular transection. 
     
     
         3 . The filler for removing wrinkles according to  claim 2 , wherein the main body has a diameter of 0.6-1.0 mm, and the hollow portion has a diameter of 0.5-0.7 mm. 
     
     
         4 . The filler for removing wrinkles according to  claim 2 , wherein the through-holes have a diameter or a circle-equivalent diameter of 40-500 μm. 
     
     
         5 . The filler for removing wrinkles according to  claim 1 , wherein the main body is formed by spirally winding a plurality of strip-shaped parts so as to cross each other, such that the hollow portion is provided in the parts in a lengthwise direction, and the through-holes communicating with the hollow portion from the outer surface of the main body are provided by the gaps between the parts. 
     
     
         6 . The filler for removing wrinkles according to  claim 1 , wherein the main body is made of an elastic material.

         8 . The filler for removing wrinkles according to  claim 1 , wherein the main body is made of a non-biodegradable polymer selected from a group consisting of nylon, silicone and Teflon. 
     
     
         9 . The filler for removing wrinkles according to  claim 1 , wherein the main body has a double-layer structure comprising an inner sheath and an outer sheath made of different materials having different physical properties. 
     
     
         10 . The filler for removing wrinkles according to  claim 1 , wherein a plurality of partitions are further formed in the hollow portion. 
     
     
         11 . The filler for removing wrinkles according to  claim 1 , wherein a spiral elastic support is further formed in the hollow portion. 
     
     
         12 . The filler for removing wrinkles according to  claim 1 , wherein a spiral elastic support is further provided outside the main body so as to surround the outer surface of the main body. 
     
     
         13 . The filler for removing wrinkles according to  claim 1 , wherein a plurality of the main bodies are disposed in a row such that the hollow portions are adjacent to each other, and a connector penetrating the hollow portions formed in the main bodies in a lengthwise direction is further provided so that the plurality of main bodies are used as a series of fillers for removing wrinkles 
     
     
         14 . The filler for removing wrinkles according to  claim 1 , wherein a plurality of elastic projections projecting in one direction are further formed on the outer surface of the main body along the lengthwise direction of the main body. 
     
     
         15 . The filler for removing wrinkles according to  claim 1 , wherein growth factors for facilitating the formation of fibrous tissue are coated on the outer surface or inner surface of the main body or included in the main body.
