Embodiment Construction
[0033] refer to figure 1 , one A pointed biofilm for improving fracture healing, comprising an elastic layer 1 and a drug layer 2 from inside to outside, the elastic layer 1 is a dense biofilm that can be degraded or absorbed, and the material of the drug layer 2 is made of human bone biophase Good degradation or non-degradation, absorption or non-absorption or porous loose material, medicine layer 2 is also encapsulated inside the drug that can promote bone healing. The biological microstructure membrane is a strip-shaped folded structure with a "V"-shaped cross-section, an elastic layer 1 inside and a drug layer 2 outside. The width and depth ratio of the "V"-shaped cross-section is 1, and its width The gap between the broken bone surfaces that are spliced together after fracture surgery. The periphery of the biomicrostructure membrane is sealed with medical bioglue that is impermeable to nerve growth stimulating factor and stem cells. The elastic layer 1 is made of po...
