The invention relates to the technical field of medical devices, in particular to a biomimetic intervertebral fusion cage and a preparation method thereof; the biomimetic intervertebral cage includes alloy parts and peek injection molding parts, and the alloy parts include a porous structure, a support frame and an anti-dislocation Teeth, the support frame is set on the outer side wall of the peek injection molding part, the support frame is filled with porous structure, the anti-detachment teeth are fixedly connected with the support frame, the injection mold is designed according to the designed 3D data, and the 3D printing technology is used to manufacture the alloy parts. The alloy parts are placed inside the mold cavity for injection molding, and the hot-melted peek material enters the injection cavity through the injection port to fill the reserved injection molding space. After injection molding, the alloy parts are tightly connected with the peek injection molding parts to complete the biomimetic cone In the manufacture of the intervertebral cage, the bone ingrowth ability of the intervertebral cage is improved through the above structure, the mechanical properties of the peek and alloy composite intervertebral cage are improved, the occurrence of stress shielding is avoided, and settlement is prevented. |
