The invention belongs to the field of biomedical materials, and discloses a starch gel hemostatic material based on 3D printing technology and a preparation method and application thereof. On the basis of greatly improving the water absorption performance of starch, a new type of personalized material processing 3D printing technology was further used to synergize with loading coagulation factors to construct a fast gel hemostatic material with both active and passive hemostatic functions, so as to achieve the effect of accelerating skin wound healing. The starch gel hemostatic material prepared by the invention has good liquid absorption, high hemostatic efficiency and wound healing promotion rate, and also has excellent biodegradation performance and cell compatibility. The preparation method of the invention is simple, and can be customized according to requirements and industrialized in large quantities, which will provide technical support for the preparation of safe and high-performance functional starch gel hemostatic materials. |
