3D printing self-stabilizing cervical interbody fusion cage

A three dimensional (3D) printed self-stabilizing interbody fusion cage, comprising:

• a fusion cage body, comprising
• a front side surface with four corners, wherein first concave-convex groove plates are mounted at upper and lower positions of the front side surface of the fusion cage body,
• wherein circular arc notches are formed in each of the four corners, and wherein interiors of each of the circular arc notches comprise threaded openings, and
• wherein a reserved circular opening formed in a middle portion of the front side surface of the fusion cage body, wherein the fusion cage body comprises an inner wall of a circular arc structure, and
• a side surface, wherein said side surface comprises a square opening;
• and
• screws mounted in the threaded openings of the fusion cage body, wherein the screws are self-tapping screws with threads, and the threads of the screws are in fit with threads of inner walls of the circular arc notches,
• wherein the fusion cage body and the screws are integrally formed by 3D printing.
