23 Jul 3D printed PCL-Li bone tissue engineering scaffold, and preparation method thereof
Abstract
The invention discloses a 3D printed PCL-Li bone tissue engineering scaffold, and a preparation method thereof. According to the preparation method, epsilon-caprolactone PCL and lithium chloride are taken as raw materials of the 3D printed PCL-Li bone tissue engineering scaffold, 3D printing technology is adopted to prepare the 3D printed PCL-Li bone tissue engineering scaffold. After of implantation of the 3D printed PCL-Li bone tissue engineering scaffold into human body, PCL is degraded gradually as a biologically absorbable material, Li is released to promote osteochondral osteogenesis; and in addition, a porous structure of the 3D printed PCL-Li bone tissue engineering scaffold is capable of inducing bone ingrowth, and repairing of bone defects caused by bone wound, tumor, and infection can be realized. The 3D printed PCL-Li bone tissue engineering scaffold is simple and reliable in structure; the appearance and the microstructure are controllable; the mechanical properties are reliable; ion release properties are controllable; implantation is convenient; wound is small; and cost is low.
