Abstract:
OBJECTIVE: To introduce the sorts of biomedical fibers, collagenous fibers, chitin fibers polyactic acid(PLA) fibers, etc. , and their preparation,properties and application respectively, and suggest China to pay attention to the research and development of biomedical fiber.DATA SOURCES: Literatures from January 1993 to December 2001 were computer-searched in http://www.sciencedirect.com, http://worldscinet.lib.tsinghua.edu.cn, with the key words of "biomedical and polymer,fibre" and the language was limited to English.: Literatures from January 1999 to December 2004 were computer-searched in http://www.wanfangdata.com.cn,with the key words of "Biological, medical, polymer and Chitin Fibers" and the language was limited to Chinese.STUDY SELECTION: Inclusion criteria: ①Chitin fibers②Collagenous fibers and PLA fibers③Alginic acid fibers④Polyglycolide fibers⑤β-hy droxybutanoic acid ester (PHB)⑥Polycaprolactone fiber. Exclusion criteria:① Obsolete literatures. ② Repeated study. DATA EXTRACTION: Totally 60 tests on biomedical fiber were collected, but only 15 literatures met the inclusion criteria. Altogether 45 literatures were excluded due to older and repeated study.DATA SYNTHESIS: ①The sorts of biomedical fibers: Classified according to the sources, biomedical fibers include metal ones (e.g. stainless steel wire), inorganic and nonmetal ones (e.g. alumina fibers) and macromolecular ones. Classified according to the interaction between living tissues and materials, they include bioinert fibers, bioactive fibers and bioabsobable fibers. Classified according to biomedical use, they include biomedical fibers compatible with hard tissues, biomedical fibers compatible with parenchyma, biomedical fibers compatible with blood and biomedical fibers used as medicine or for regulating the release of medicine ②The main biodegradable fibers include chitin fibers, collagenous fibers, PLA fibers and their copolymer fibers.CONCLUSION: As one of the important functional fibers, the biomedical fibers attract wide attention both at home and abroad. The research and development about them are still on the way and has shown hopeful prospective of application. Much attention should be paid on the research and development of biomechanical fibres.
