Embodiment Construction
[0031] refer to figure 1 , 2 Circular biofilm 1 with a cross-shaped cross-section, including a hollow biofilm folded into a cross-shaped cross-section, with four vertex angles of "U", and the vertex angles coincide with the fracture line section, and the inner layer of the biofilm is an elastic layer The outer layer is a drug layer and an elastic layer, which is a dense degradable or non-degradable biofilm. The material of the drug layer is a degradable or non-degradable, absorbent or non-absorbable or porous material that is biocompatible with human bone. Drugs that can promote bone healing are also encapsulated inside the drug layer. After the circular biofilm 1 with a cross-section is cut, four "U"-shaped unit biofilms 2 are formed.
