Abstract:

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.
