The invention provides a sodium alginate microsphere filling material. The filling material is made from the following raw materials in parts by weight: 30-50 parts of sodium alginate, 5-15 parts of gelatin, 0.5-5 parts of chitosan, adsorption 0.1-3 parts of agent, 5-10 parts of cross-linking agent, and 100-200 parts of normal saline. The various components in the sodium alginate microsphere filling material of the invention have good biocompatibility, cross-link each other, effectively prevent the degradation of hyaluronic acid, and have stable filling plastic in the body, good shaping effect, and overcome the The use of cross-linked hyaluronic acid is prone to the defect of biological toxicity. |
