Embodiment Construction
[0032] refer to figure 1 An array of three-layer circular composite membranes, including an elastic layer 1, a drug layer 2, and a guide layer 3 from the inside to the outside. The elastic layer is a dense degradable or non-degradable biofilm. The drug sustained-release system with promoting effect is made of degradable or absorbable material that is biocompatible with human bone, and the material of the guide layer is degradable or non-degradable, absorbable or non-degradable material that is biocompatible with human bone. Absorbed porous and loose matter, the shape of the biofilm is a structure in which unit biological particles 4 are arranged in an array, and the bottom 5 of each unit biological particle 4 is spaced 3-5 mm apart from each other, and the unit biological particles 4 are folded in a long strip Structure, the cross section is "U" shape, the inner part is the elastic layer, and the outermost part is the drug layer. The width and depth ratio of the "U" shape cros...
