High strength biodegradable surgical threads are in demand for surgical practice. Nowadays, such threads can be made of metallic materials such as magnesium, zinc or alloys based on these metals. In current paper, manufacturing technology of biodegradable surgical threads of Mg–Ca alloys and of pure Zn was developed and basic properties of the obtained product have been characterized. The influence of in vitro corrosion in bovine serum simulating environment in the mammal’s body on the surgical threads mechanical properties was determined. It was found that Zn and hot extruded alloys MgCa0.9 and MgCa1.2 can be recommended as a candidate for the future study in vivo. Properties of the room temperature drawn wires of the alloy MgCa0.7 are not sufficient for its application as surgical threads.

体外腐蚀对金属高强度可生物降解外科线的力学性能的影响

需要高强度的可生物降解的外科手术线以用于外科手术实践。如今，这种线可以由金属材料制成，例如镁，锌或基于这些金属的合金。在当前的论文中，已开发了Mg-Ca合金和纯Zn的可生物降解外科线的制造技术，并表征了所得产品的基本性能。确定了体外在哺乳动物体内牛血清模拟环境中的腐蚀对手术线力学性能的影响。发现锌和热挤压合金MgCa0.9和MgCa1.2可被推荐作为未来体内研究的候选对象。MgCa0.7合金的室温拉丝的性能不足以用作外科手术线。
