23 Jul Method for preparing integrated frame fabrication of cartilage of tissue-engineered bone having function interface
Abstract
The present invention discloses process of preparing integral bionic tissue engineering bone-cartilage rack with functional interface. The process includes the first establishment of CAD model of the integral bone-cartilage rack by means of bionic principle; preparing collagen/chitosan and collagen/hydroxyapatite micro polymer powder; converting the CAD model into fast forming file input into a 3D printing fast forming machine, spreading the powder with one powder spreader, spraying pentanedial adhesive selectively on the spread powder for adhering and eliminating excessive powder to obtain the integral bionic tissue engineering bone-cartilage rack with functional interface. The present invention has excellent biocompatibility, controllable cartilage rack degrading speed and mechanical strength and other advantages.
