摘要
The present invention relates to the controllable degradation, filling-type complex bone implant of multivariant amino acid polymer-organic calcium/phosphorus salts, as well as to the preparative method thereof. The complex bone implant is consisted of multivariant amino acid polymers and medically acceptable organic calcium/phosphorus salts, while the content of organic calcium/phosphorus salts is 20-90% based on the total mass of composite material; the multivariant amino acid polymer is polymerized by ε-aminocaproic acid and at least two other amino acids, in which the molar content of ε-aminocaproic acid is at least 50% of the total molar quantity of amino acid polymers, while the amounts of other amino acids are at least 0.5% of the total molar quantity of amino acid polymers.
