Embodiment Construction
[0033] refer to figure 1 1. A batch production method of pointed three-layer biofilm, comprising the following steps:
[0034] 1) Make a long strip model 1 with a star-shaped cross-section, four "V"-shaped top corners, and the top corners coincide with the fracture line cross-section;
[0035] 2) Immerse the strip-shaped model 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, and the second solution layer forms a drug layer. Encapsulate a drug slow-release system that can promote bone healing. The material is a degradable or absorbable substance that is well compatible with human bone biocompatibility. The third solution layer forms a guiding layer, and the material is biocompatible with human bone. Porous and loose substances that are well compatible, degradable or non-degradable, absorbent or non-absorbent;
[0036] 3) After the ...
