Embodiment Construction
[0036] refer to figure 1 , 2 1. A batch production method of pointed three-layer biofilm, comprising the following steps:
[0037] 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;
[0038]2) The model is immersed in the first solution layer, the second solution layer, and the third solution layer in sequence. The first solution forms an elastic layer, which is a dense degradable or non-degradable biofilm. The second solution layer forms a drug layer, which encapsulates The drug slow-release system that can promote bone healing is made of degradable or absorbable substances that are biocompatible with human bone. The third solution layer forms a guiding layer, and the material is biocompatible with human bone. Degradable or non-degradable, absorbent or non-absorbable porous and loose substances;
[0039] 3) After the biological microstructure membrane is air-dried a...
