Embodiment Construction
[0036] refer to figure 1 , the method for making the model array of the three-layer circular composite membrane, 1) make the model 4 whose apex angle section is "U" and coincides with the fracture line section in advance, and the "U" model 4 is combined into an array close to each other, and each The bottoms of each "U" model 4 are 3-5 mm apart from each other;
[0037]2) Wet elastic layer, drug layer, and guide layer are made respectively, the elastic layer 1 is a dense biodegradable or non-degradable biofilm, and the drug layer 2 is encapsulated with a drug slow-release system that can promote bone healing, The material is a degradable or absorbable material that is biocompatible with human bone, and the material of the guide layer 3 is a porous and loose material that is biocompatible with human bone, degradable or non-degradable, absorbent or non-absorbable;
[0038] 3) Cover the wet elastic layer on the model array, wrap the top corners of each model 4 in the array and e...
