This invention relates to a 3D-printed cuttlebone elastic hemostatic scaffold and its construction method. Existing hemostatic materials suffer from problems such as effectiveness only for mild to moderate bleeding, significant side effects, poor biocompatibility, and the need for compression and wound closure. This method involves dissolving a prepolymer of polyglycerol sebacate and polycaprolactone in tetrahydrofuran to prepare a polymer solution. Sodium chloride particles and cuttlebone powder are added and heated and stirred to obtain the 3D printing ink. This ink is then placed in a 3D printer to print sheet-like and block-like mesh scaffolds. The mesh scaffolds are then placed in a vacuum drying oven for vacuum thermal cross-linking. After cross-linking, they are immersed in distilled water for washing and desalting, and then freeze-dried to obtain the hemostatic scaffold. The hemostatic scaffold of this invention is particularly suitable for systemic lacunar wounds with deep bleeding sites that are difficult to control with compression. By combining a biodegradable elastic biopolymer with the traditional hemostatic drug cuttlebone powder, it possesses advantages such as porosity, elastic memory, rapid hemostasis, compressibility, and biodegradability.

This invention provides a cuttlebone-derived material, its preparation method, and its application, belonging to the technical field of water purification. In this invention, cuttlebone is mainly composed of calcium carbonate and chitin complex protein. Lead has a strong coordination effect with the hydroxyl and amino functional groups on chitin, and lead is adsorbed by calcium carbonate through ion exchange and surface precipitation. Furthermore, the natural macroporous structure of cuttlebone facilitates rapid and efficient lead adsorption. Calcination at 500°C in the absence of oxygen causes the calcium carbonate component in the cuttlebone to transform from an aragonite crystal form to a calcite crystal form. The calcite crystal form has a stronger ion exchange capacity for lead than the aragonite crystal form, thus improving the adsorption performance of the cuttlebone raw material.
