本发明提供了一种生物可降解的医用镁合金补片及其制备方法和用途，属于医用耗材的技术领域。其特点是采用由截面为圆形、椭圆形或长方形(扁条状)的镁合金丝材编织成多孔的网状结构，所述网状结构上设有可吸收涂层。该补片还可通过压合可吸收膜层，制备成不同的带覆膜补片，应用于不同的临床手术适应症。本发明制备的补片具有低厚度，高强度、柔韧性和生物相容性好等优点，并且植入人体后一定时间内维持较高的力学性能，同时在患者伤口愈合后可降解被人体所吸收，在体内无残留，减轻患者愈合后期的不适感和不良反应。

The invention provides a biodegradable medical magnesium alloy patch and a preparation method and application thereof, belonging to the technical field of medical consumables. It is characterized by the use of a round, oval or rectangular (flat strip) magnesium alloy wire woven into a porous network structure, the network structure is provided with an absorbable coating. The mesh can also be made into different coated patches by pressing absorbable film layers, which can be used in different clinical surgical indications. The mesh prepared by the invention has the advantages of low thickness, high strength, flexibility and good biocompatibility, and maintains high mechanical properties for a certain period of time after implantation into the human body. At the same time, it can be degraded and absorbed by the human body after wound healing, and has no residue in the body, so as to reduce the discomfort and adverse reactions in the later healing period of the patient.
