Abstract

The invention discloses a medical suture material and a preparation method. The medical suture material comprises components in parts by weight as follows: 110-140 parts of magnesium, 1-2 parts of zinc, 0.1-0.4 parts of aluminum, 3-5 parts of molybdenum, 2-2.5 parts of calcium, 0.1 parts of carbon, 4-6 parts of niobium, 0.5-1 part of iron, 1-2 parts of manganese, 0.5-1 part of germanium, 1-2 parts of zirconium and 0.05-0.1 parts of titanium. The medical suture material has very high strength and elongation at break, is easily degradable and has good corrosion resistance and biocompatibility.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical suture material and a preparation method. Background technique [0002] Biomedical materials, also known as biomaterials, refer to the diagnosis, treatment, surgical repair, physiotherapy rehabilitation, replacement of biological tissues or organs (artificial organs) for diseases of biological systems, and the enhancement or restoration of their functions without harming human tissues. Materials with adverse effects, biomedical materials perform healing by directly combining and interacting with living organisms. With the development of modern medicine and material science, medical prosthetics, artificial joints, bone plates, bone marrow nails, cardiovascular stents, dental implants, heart valve covers, sutures, etc. Human body or artificial organs and auxiliary treatment equipment are increasingly widely used in the medical and health field. As the materials f...
