新型肝脏止血捆扎带的研制

背景：如何有效控制肝切除术中出血是降低病死率和术后并发症的关键。目的：寻找适合临床手术需要的材料制作出新型肝脏止血捆扎带。方法：选取对人体无毒无害的常用医用材料：聚四氟乙烯、氟化乙烯丙烯共聚物、乙烯-四氟乙烯共聚物、全氟烷氧基聚合物、尼龙、尼龙弹性体、聚碳酸酯、聚乙烯、聚氨酯、聚丙烯,分为10组,每组随机选取10份样品测量其物理机械性能。结果与结论：尼龙具有相对密度轻,强度高,摩擦因数小,易加工,经济实惠等特点,适合用于制作肝脏血流捆扎带的材料。

Preparation of a new liver blood inflow banding

BACKGROUND： To effectively control the bleeding during liver resection is the key to reduce postoperative mortality and complications. OBJECTIVE： To find a new liver blood inflow banding to provide a new way of liver blood inflow occlusion. METHODS： Harmless materials were chosen： polytetrafluoroethylene, fluorinated ethylene propylene copolymer, ethylene-tetrafluoroethylene copolymer, Perfluoroalkoxy polymer, nylon, nylon elastomer, polycarbonate, polyethylene, polyurethane, polypropylene, divided into 10 groups. Ten samples were randomly selected from each group to measure the physical and mechanical properties. RESULTS AND CONCLUSION： Nylon with a light weight, high strength, small friction coefficient, easy to process, low cost and other characteristics, make it suitable to produce hepatic blood flow banding material.
