Abstract: A flexible intervertebral cage with opening is provided, including a main body, a porous structure part, a side opening, and a rear opening. The porous structure part is arranged at the corresponding positions of the upper and lower parts of the main body; the side opening are located on the two sides of the main body that are different from the upper and lower parts, and the rear opening is located at the other ends of the upper and lower parts of the main body opposite to the end part that connects the upper and lower part. As such, a C-shaped opening structure is used to effectively reduce stress shielding and stress transfer. The biomimetic porous structure of the structural part can promote the attachment and growth of bone cells.

Abstract: A surface-treated intervertebral fusion cage is provided, including a main body and a porous structure portion. The porous structure portion is arranged at the corresponding position of the upper and lower parts of the main body. The surface-treated intervertebral fusion cage can improve the biocompatibility, and the surface etching and thermal treatment can increase the coating coverage and increase the mechanical toughness of the cage of the present invention.

Abstract: The present invention relates to a glass-ceramic composite material, which is a composite material with degradability and osteoconductivity, and is composed of CaO—MgO—SiO2 (CMS glass)+CaMgSi2O6 (CMS ceramic) and CaSO4 (CS ceramic). In addition to the CaO—MgO—SiO2 glass, this synthesized composite material mainly includes two ceramics of CaMgSi2O6 and CaSO4 in crystalline phase, wherein, both the CMS glass and CMS ceramic have high mechanical strength, biocompatibility and osteoconductivity, while CaSO4 has the characteristics of rapid degradation to promote bone ingrowth.

Abstract: A glass ceramic manufactured by sequentially performing the processes of melting and thermal decomposition, water quenching and sintering of a glass composite. The glass ceramic includes 38 wt % to 49 wt % CaO, 41 wt % to 52 wt % SiO2 and 0.1 wt % to 20 wt % P2O5. The glass composite includes a glass component and P2O5, and the glass component includes CaCO3 and SiO2 and does not include an alkali metal oxide. The melting and thermal composition temperature is from 1350° C. to 1650° C. The sintering temperature is from 750° C. to 1050° C. By the combination of CaO, SiO2 and P2O5 and the control of the contents of CaO, SiO2 and P2O5 within the aforementioned ranges, and the glass ceramic contains no alkali metal oxide, the glass ceramic has good mechanical strength and low cytotoxicity.
