PURPOSE:To facilitate the passing of a suture through a hole of a bone while preventing possible breakage of an edge of the suture by connecting a needle part, a file part and a synthetic fiber of the suture comprising them in the order. CONSTITUTION:A needle part 1 uses a metal needle made of stainless steel. When a suture 3 comprising a synthetic fiber is made up of a multifilament, the hardness of an end is heightened by fusing or impregnation with a fixative. A file part 2 comprises a metallic wire, signal line, chain or a mixture thereof with the synthetic fiber, hence having a sufficient hardness. Moreover, to connect the file part 2 to the suture 3, a powder for polishing such as melt alumina may be attached to the surface of the suture. The suture 3 herein used is a fibrous matter made of polyester, polyethylene, polypropylene or the like. To fix a bone having a cracking or the like using a suture material assembly 4 for surgery, a hole 6 is opened in bones 5a and 5b and the needle part 1 inserted through the hole 6 made in the bone. Then, a sharp edge 8 of the bone generated in the perimeter of the hole is scraped off with the file part 2. Finally, after the bone 5a is fixed firmly with the suture 3, the needle part 1 and the file part 2 are cut off. |
