Embodiment Construction
[0030] refer to figure 1 1. Batch production molds for circular biofilms, comprising the following steps:
[0031] 1) Make a model 1 with an elliptical cross section, a "U"-shaped top angle on the long side, and the top angle coincides with the fracture line section;
[0032] 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;
[0033] 3) After the biological microstructure membrane is air-dried and the shape is fixed, cut the prepared biological microstructure membrane 1 along the circumference of the ellipse of the model section according to the required size, and pe...
