Embodiment Construction
[0016] As shown in Figure 1, 1-cartilage layer, 2-calcification layer, 3-subchondral bone layer, 4-pore,
[0017]The integrated engineering support of the present invention is composed of a cartilage layer 1, a calcification layer 2 and a subchondral bone layer 3 from top to bottom, and organically connects between the cartilage layer 1 and the calcification layer 2, and between the calcification layer 2 and the subchondral bone layer 3 , the cartilage layer 1 and the subchondral bone layer 3 are closely connected by means of the special composition and structure of the calcification layer 2, and are organically connected to each other. There is no boundary between each layer, but the structure and composition of each layer are different. The composition material of the cartilage layer 1 is medical type II collagen and chitosan; the weight ratio of type II collagen is 80% to 90%, and the weight ratio of chitosan is 10% to 20%, and the weight ratio of type II collagen / chitosan i...
