This product is an intelligent bone repair scaffold that integrates 4D printing with photothermal-responsive materials. Its core lies in endowing the material with excellent photothermal properties. The material can efficiently convert light energy into heat, driving the scaffold to achieve rapid and controllable intelligent transformation during the smart recovery process. This technology overcomes the limitations of traditional implants with fixed shapes, providing a revolutionary solution for personalized, minimally invasive repair of complex bone injuries, and has significant application value in fields such as craniofacial reconstruction.
