The nerve repair material and conduit that one kind has tremella polysaccharide are closed in system of the present invention,The material includes a substrate being prepared by the high molecular material of biocompatibility and/or Biodegradable,And substrate surface coating or it is grafted with one with a thickness of 0.1 ~ 10 μm of tremella polysaccharide,And nerve trachea can be made in this material； Also can what high molecular material be made to be added in conduit and have plural number by the compound nanometer particle of tremella polysaccharide-positive electricity polysaccharide of tremella polysaccharide and at least one positive electricity polysaccharide preparation,Wherein the ratio system of the tremella polysaccharide in those nanometer particles accounts for 20% ~ 80% (w/w) of nanometer particle total amount,And the partial size of those nanometer particles is 30 ~ 300nm. Wherein, the group which forms selected from polylactic acid, the poly- glycol acid copolymer of polylactic acid-, poly- Glycolic acid and polylactic acid-polycaprolactone co-polymer, and the molecular weight of tremella polysaccharide is 500 ~ 5,000kDa. The reparation and regeneration of injured nerve can be effectively facilitated by the nerve rehabilitating tube that those include tremella polysaccharide.本發明係關於一種具有銀耳多醣之神經修復材料及導管，該材料包含一由生物相容性及/或生物可分解性之高分子材料製備成之基材，且該基材表面塗佈或接枝有一厚度為0.1~10μm之銀耳多醣，並可將此材料製成神經導管；亦可於高分子材料製成導管內加入有複數顆由銀耳多醣與至少一種正電多醣製備之銀耳多醣-正電多醣複合奈米微粒，其中該些奈米微粒中之銀耳多醣的比例係佔奈米微粒總量之20%~80%(w/w)，且該些奈米微粒之粒徑為30~300nm。其中，該高分子材料係選自聚乳酸、聚乳酸-聚甘醇酸共聚物、聚甘醇酸與聚乳酸-聚己內酯共聚物所組成之族群，而銀耳多醣之分子量為500~5,000kDa。藉由該些包含有銀耳多醣之神經修復導管可有效促進受損神經之修復與再生。
