Abstract:
Making bone scaffold through tissue engineering method presents a new choice for both the patients and the doctors of orthopaedics. The biodegradable polymer PLA is chosen to make porous fundus scaffold jetting through special designed nozzle on multi-functional rapid prototyping machine controlled by computer according to the CT data CAD model. The scaffold is then chemically aggregated to compound with collagen-hydroxyapatite, and the ideal bone repair material is obtained. Animal experiment has indicated the correctness of this conclusion.
