Abstract

The invention discloses a high strength femoral head plasticising material, which comprises the following raw materials by weight part: 15-20 parts of coral knoll, 6-8 parts of cuttlebone, 2-4 parts of polymethyl methacrylate, 5-7 parts of hydroxy apatite, 1.2-1.5 parts of nano cellulose, 2-4 parts of polylactic acid, and 15-18 parts of 1,4-dioxane. In the invention, cuttlebone has reproducibility, provides good tunnel for health development of regenerated tissue and can satisfy the required flexibility; coral knoll is taken as a main material, hydroxy apatite and nano cellulose are added, biology compatibility, bone conduction characteristic and good mechanical strength of the material can be greatly increased, raw material source is abundant, the preparation process is simple, and the high strength femoral head plasticising material has wide application prospect.

Description

technical field [0001] The invention belongs to the technical field of medical materials, and in particular relates to a high-strength femoral head plasticized material. Background technique [0002] Stony corals are distributed in tropical shallow seas, mainly in groups, and live in symbiosis with unicellular dinoflagellates, called reef-building corals. The optimum water temperature is 25-29°C, and it will die below 13°C. The suitable salinity is 27-40. Requires clean sea water, hard substrate. Stony corals can be used as raw materials for lime, building materials, and the cornerstone of economic algae (eucheuma and spaghetti algae). In addition, it can also be used as a medicinal natural compound. [0003] Cuttlebone is the inner shell of cuttlefish or golden squid. Produced in China's coastal areas such as Liaoning, Jiangsu, Zhejiang and other places. Protozoan is carnivorous and lives on the seabed. Efficacy Convergence and hemostasis, strengthening essence and s...
