23 Jul Compound system implanter unit for local tissue engineering
Abstract
The invention discloses a local structure engineering compound system implantation unit in the medical engineering domain, which comprises the following parts: polylactic acid/ Gegenbaur’s osteoblast architecture and titanium/titanium ball-bioactivity ceramics architecture, wherein the polylactic acid/ Gegenbaur’s osteoblast architecture is formed by compositing of polylactic acid slice and autologous Gegenbaur’s osteoblast forming by external evoking; the equidistant feed-through is spread all over the polylactic acid slice; the titanium/titanium ball-bioactivity ceramics architecture includes titanium ball texture surface, round feed-through and metal base, bioactivity ceramic film; the titanium ball texture surface is formed with titanium ball in parallel array; the titanium ball corresponds to feed-through of polylactic acid slice; the bioactivity active ceramic film is covered on titanium ball texture surface, inner surface of round feed-through and the surface of metal base. The invention can assemble on labourer joint surface, which replaces artificial bone replacement to restore bone defection.
