Hydrogel composite scaffold capable of improving cartilage repair capability

The invention discloses a hydrogel composite scaffold capable of improving cartilage repair capacity, and belongs to the technical field of medical instruments. The hydrogel composite scaffold is mainly prepared by compounding double-layer hydroxyethyl cellulose/polyvinyl alcohol nanofiber with carboxymethyl chitosan/soybean protein hydrogel, and the double-layer hydroxyethyl cellulose/polyvinyl alcohol nanofiber is divided into a double-layer structure of an arrangement layer and a random layer. The molecular structure of the soybean protein is similar to that of natural protein in bone tissue, and bioactive molecules such as extracellular matrix protein and estrogen can be provided; the bilayer hydroxyethyl cellulose/polyvinyl alcohol nanofiber can induce differentiation of osteoblasts and myoblasts. The double-layer hydroxyethyl cellulose/polyvinyl alcohol nanofiber and carboxymethyl chitosan/soybean protein are crosslinked to prepare the hydrogel composite scaffold, and the hydrogel composite scaffold not
