PROBLEM TO BE SOLVED: To obtain a material which has excellent biocompatibility and is effective for reproduction of the tissue having adequate strength and degradation rate by forming a vital material containing calcium phosphate and a lactic acid/glycolic acid/εcaprolatone copolymer. SOLUTION: The vital material is formed of the structure in which the calcium phosphate is coordinated with the carbonyl group of the lactic acid/ glycolic acid/ε-caprolatone copolymer and, therefore, adjusts the in-vivo degradability and vital tissue derivability of the calcium phosphate, thereby greatly accelerating the vital tissue derivability. While the shapes of the vital tissue to be rebuilt are intricate in general, various kinds of the materials from flexibility to high strength are molded by adjusting the tissue and molecular weight of the lactic acid/glycolic acid/εcaprolatone copolymer and, therefore, the vital material is not deformed by the oppression of the tissue and the fixation in tight contact with the tissue is possible. Also, the adjustment to the decomposition rate suitable for the damage of application parts is possible and, therefore, the rapid tissue restoration is made possible without the hindrance of the reproduction of the vital tissue. |
