Embodiment Construction
[0035] refer to figure 1 , 2 , 1) Make a model in advance with a diamond-shaped section, a "V"-shaped apex angle on the long side, and a coincident apex angle with the fracture line section;
[0036] 2) Immerse the model in the first solution layer and the second solution layer in turn. The first solution forms an elastic layer, which is a dense degradable or non-degradable biofilm. The second solution layer forms a drug layer, and the material of the drug layer is human bone Biocompatible degradable or non-degradable, absorbent or non-absorbable or porous porous substances, and drugs that can promote bone healing are also encapsulated inside the drug layer;
[0037] 3) After the biological microstructure membrane is air-dried and the shape is fixed, cut the prepared biological microstructure membrane along the circumference of the model section according to the required size, and peel off the cut ring-shaped biofilm from the top corner of the model;
[0038] 4) Cut the ring...
