Abstract

The invention belongs to the technical field of implant materials, and particularly relates to a magnesium alloy microtubule for medical implantation and a preparation method thereof.A magnesium-based metal coating is evenly prepared on the surface of a bar through a coating deposition technology, then a bar base body is removed through a melting method, and therefore, the magnesium-based metal microtubule is obtained. The microtubule is characterized in that the tube diameter thereof is 1-5mm, the thickness of the tube wall is 50-500[mu]m, and the base body is made of any one of low-melting-point metal bismuth, indium and tin or a quartz glass tube. Compared with the prior art, the magnesium alloy microtube has the beneficial effects that 1) the requirements of different implantation parts on mechanical properties and structures are met, 2) the magnesium alloy ,microtube has good biocompatibility, an alkaline environment generated by degradation of magnesium in vivo is utilized to provide an antibacterial function, and magnesium ions generated by degradation and beneficial alloy elements promote cell proliferation, so that repair of blood vessels and nerves is promoted; 3) the problem of difficulty in traditional plastic processing of the magnesium-based metal microtube is avoided, and 4) different sizes of magnesium-based metal microtubes can be manufactured, and the degradation speed is controllable.

Description

technical field

[0001] The invention belongs to the technical field of nerve repair implants, cardiovascular and cerebrovascular repairs, and antibacterial implant materials, and in particular relates to a magnesium-based metal microtube for medical implantation and a preparation method thereof. Background technique

[0002] Peripheral nerve injury caused by trauma, nerve degeneration, ischemia and hypoxia has become one of the common clinical diseases. Once the nerve is broken and damaged, the nerve signal transmission pathway will be interrupted, the corresponding organ function will be affected, and the body function will be impaired, which will seriously affect people's quality of life. In addition, the ability of neurons to regenerate is weak and the nervous system is difficult to remodel. Once nerve damage occurs, it is difficult to recover. Therefore, the repair of damaged nerves has always been a hot and difficult point in the medical field. At present, autologous ...
