Flow guide tube in interposition jejunum operation and method thereof

The invention belongs to the field of interposition surgical materials and facilities, and particularly relates to a flow guide tube in interposition jejunum operation and a method thereof. The flow guide tube comprises a plurality of interfaces and an artificial tube, the interfaces are arranged at the two ends of the artificial tube, the artificial tube is arranged to be an elastic material simulation model with supporting strength, the interfaces are arranged to be an anti-fistula model, and anti-inflammatory and anti-repelling medical coatings are arranged on the outer surfaces of the interfaces. The flow guide tube and the interfaces of the flow guide tube have various selectable flow guide modes and are suitable for different interposition operations; the interfaces comprise an innersilicon rubber layer, an outer silicon rubber layer and a middle titanium alloy layer, an anti-inflammatory and anti-repelling medical coating is arranged on the outer surface of the interface, the interfaces provide anastom
