Preparation method of high-purity magnesium rod for preparing degradable medical anchor

The invention discloses a preparation method of a high-purity magnesium rod for preparing a degradable medical anchor. The preparation method comprises the following steps: (1) dicing; (2) cleaning; (3) vacuum packaging; in the preparation process, air can be isolated, oxidation is avoided, the preparation efficiency is high, the length range of the extrusion bar formed through extrusion can be several meters to hundreds of meters or above, densification of sponge-state ultra-high-purity magnesium can be achieved at the low temperature, extrusion deformation can be completed at the low temperature, and the mechanical property of the high-purity magnesium bar is improved. 本发明公开了一种用于制备可降解医用锚钉的高纯镁棒的制备方法，步骤包括1）切块，2）清理，3）真空封装，4）热等静压致密化，5）挤压加工。本发明制备过程可以隔绝空气，避免氧化，制备效率高，挤压成形挤出棒材长度范围可为几米到百米以上，可以在较低温度下实现海绵态超高纯镁致密化并在较低温度下完成挤压变形，提高高纯镁棒的力学性能。
