Embodiment Construction
[0032] refer to figure 1 1. A cross-shaped mold for mass production of circular biofilms, 1) To manufacture a wax model 1 with a cross-shaped cross-section, four top corners of "U", and the top corners coincide with the fracture line cross-section.
[0033] 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;
[0034] 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 ellipse of the cross-section of the model according to the required size, and peel off th...
