Example Embodiment

[0013] like figure 1 , figure 2 As shown, the present invention is composed of hydroxyapatite powder, biological titanium sheet, and biological titanium screw. Hydroxyapatite powder 1 completely covers the surface of biological titanium sheet 2; Diameter: 8-30cm, arc height: 0.5-10cm, thickness: 0.5-1.5mm; there are fixing holes 3 on the outer ring of the arc surface, and drainage growth holes 4 on the inner ring; biological titanium screws pass through the fixing holes 3 and Cranial fixation. The fixed hole 3 and the drainage growth hole 4 may be square, diamond or circular. like image 3 As shown, the hydroxyapatite-sprayed bio-titanium cranial implant can have 4 to 5 incisions on the edge.

[0014] The preparation method of the present invention: 1. The existing biological titanium sheet (such as Figure 4 shown) stamping. 2. Plasma spraying hydroxyapatite on the semicircular arc-shaped biological titanium formed by stamping. 3. Aseptic packaging and irradiation disinf

Abstract

The cranial bone implant consists of hydroxyapatite powder, biological titanium plate and biological titanium screws. The hydroxyapatite powder covers the surface of the biological titanium plate completely. The cranical bone implant of hydroxyapatite sprayed biological titanium is semicircular one of 8-30 cm diameter, 0.5-10 cm height and 0.5-1.5 cm thickness and has fixing holes in the outer circle and drainage and growth holes in the inner circle. Its biological titanium screws are made to pass through the fixing holes for fixing with cranial bone. It has high shock resistance, and can be formed easily and fused with autogenous bone.
