Breast filling material as well as preparation method and application thereof

The invention belongs to the technical field of biological tissue engineering materials, and particularly relates to a breast filling material and a preparation method and application thereof. The breast filling material at least comprises a breast filling support model and DEL/AAM microspheres loaded on the breast filling support model; wherein the breast filling stent model is obtained by performing 3D printing on an oxidative depolymerized lignin modified polyurethane material through a melt precipitation method; the DEL/AAM microspheres are prepared from an adipose tissue acellular matrix in situ through one-step precipitation by using a droplet microfluidic technology. Experiments prove that the breast fat tissue regeneration-inducing material is good in biocompatibility, degradable, good in stability and capable of inducing breast fat tissue regeneration, and therefore the breast fat tissue regeneration-inducing material has good practical application value. 本发明属于生物组织工程材料技术领域，具体涉及一种乳房填充材料及其制备方法和应用。所述乳房填
