| titleOfInvention | A kind of ureter coating stent of medicine pipe and preparation method thereof that can gradually degrade |
| abstract | The present invention relates to the ureter coating stent of medicine pipe and preparation method thereof that one kind can gradually degrade, stand tube of the invention is woven by two kinds of fibrous raw materials with different degradation speeds；Fibrous raw material does coating treatment before braiding, includes oxidation microcrystalline cellulose and antibacterial agent in coating.The yarn that fibrous raw material is formed is knitted on the first core model and forms woven tube；It after thermal finalization, backs off to form tube body from core model, fills in the second core model at least one end of tube body, it is wrapped on polytetrafluoroethylene (PTFE) solid bar and forms cyclic structure, after thermal finalization, it is backed off from polytetrafluoroethylene (PTFE) solid bar, and the second core model is taken out, obtain ureter coating stent of medicine pipe；Oxidation microcrystalline cellulose in coating not only can be with fibrous raw material degradation in vivo together, also contain a large amount of aldehyde radical, schiff base reaction can occur with-the NH2 on urea, generate urea derivative, it excretes, to be effectively prevented from because urinating the more serious complication of mineralization bring. |
