    摘要: An intervertebral implant for positioning within an intervertebral space between adjacent first and second vertebral bodies. The intervertebral implant includes an implant body extending along a longitudinal axis of the intervertebral implant that is adapted to align with a vertical axis of the spine. The implant body includes a top plate and a bottom plate disposed longitudinally opposite and spaced apart from the top plate along the longitudinal axis. Further, the implant body includes at least one cross-arm obliquely extending between the top plate and the bottom plate. Furthermore, the implant body includes a lattice structure disposed at least between the at least one cross-arm and the top plate and between the at least one cross-arm and the bottom plate.

    摘要: The present invention discloses a metal-ceramic composite joint prosthesis and applications and a manufacturing method thereof. The joint prosthesis comprises a metal body and a ceramic body, wherein the metal body is integrally formed and comprises a porous structure layer, a boundary layer and a root-like layer, the boundary layer is located between the porous structure layer and the root-like layer, the root-like layer comprises a plurality of root-like filament clusters connected to the boundary layer but not in contact with one another, each root-like filament cluster comprises a main root perpendicularly connected to the boundary layer and a plurality of fibrous roots connected to the lateral side of the main root, the fibrous roots extend obliquely towards the side away from the boundary layer, and the ceramic body covers the root-like filament clusters and is formed on the boundary layer. The joint prosthesis achieves the compositing of metal and ceramic, thereby achieving both a wear-resistant ceramic body required for a joint friction surface and a porous metal structure with a good bone ingrowth effect required for an osseointegration surface. The root-like filament clusters of the root-like layer are rooted in the ceramic body, to form a tight and stable connection between the ceramic body and the metal body, and the root-like clusters being not in contact with one another prevents the ceramic body from locally breaking or cracking.
