生物可降解材料包括天然可降解材料和人工合成可降解材料，由它們制成的產(chǎn)品應(yīng)用于人體后可逐漸被降解吸收。本文綜述了部分已應(yīng)用于臨床的生物可降解材料的特性、種類和應(yīng)用現(xiàn)狀，其中包括甲殼素、膠原蛋白、細(xì)菌纖維素、聚羥基丁酸酯、聚乳酸、聚乙醇酸、聚對二氧環(huán)己酮和聚丁二酸丁二醇酯及磷酸鈣，并對相關(guān)的需要解決的問題進(jìn)行了討論。總之生物可降解材料所具有的理化結(jié)構(gòu)和降解特性決定其運(yùn)用于醫(yī)用產(chǎn)品將會(huì)發(fā)揮有益的治療作用，盡管目前只在有限范圍應(yīng)用，在實(shí)際應(yīng)用時(shí)也存在一些問題，但生物可降解材料將會(huì)有廣闊的應(yīng)用前景。
