Embodiment Construction
[0034] refer to figure 1 , one A method for making a pointed biofilm for improving fracture healing, comprising the following steps:
[0035] 1) Make the fracture line after artificial fracture with isolated human bone, pour wax on the fracture line, and then form model 1 after the wax solidifies. Take Model 1 off the fracture line.
[0036] 2) Prepare wet elastic layer and drug layer respectively, the elastic layer is a dense degradable or non-degradable biofilm, and the material of the drug layer is degradable or non-degradable, absorbable or non-absorbable and biocompatible with human bone Or the porous and loose material, the drug layer is also encapsulated with drugs that can promote bone healing.
[0037] 3) Cover the top corner of model 1 with the wet elastic layer, wrap the top corner of model 1 and extend to both sides of the top corner of model 1, then cover the wet drug layer on the elastic layer, and then cover the wet guide layer on the drug layer;
