Zusammenfassung:	The utility model discloses a magnesium-zinc alloy biliary stent, which relates to the technical field of biliary stents and comprises a magnesium-zinc alloy tubular support body, a spiral groove is arranged on the peripheral surface of the support body, and the spiral groove extends towards two ends of the support body on the peripheral surface of the support body. The supporting body is divided into annular supporting parts at the two ends and a spiral supporting part located between the annular supporting parts at the two ends. The magnesium-zinc alloy biliary stent is high in dimensional accuracy, good in mechanical property, high in flexibility, good in radial supporting force and long in degradation service cycle. 本实用新型公开一种镁锌合金胆道支架，涉及胆道支架技术领域，包括镁锌合金管状支撑体，支撑体外周面上设有螺旋形槽，螺旋形槽在支撑体外周面上向支撑体两端延伸，并将支撑体分割为两端的环形支撑部和位于两端的环形支撑部之间的螺旋支撑部。本实用新型的镁锌合金胆道支架尺寸精度高，力学性能好，具有高的柔顺性、良好的径向支撑力和长的降解服役周期。
