Abstract

The invention aims at providing a biomedical implantation zinc alloy material. The biomedical implantation zinc alloy material comprises, by weight, 0.1-45 parts of Cu, 0.05-5 parts of Ag, 0.01-5 parts of Au, 0.5 part of aluminum or less, 1 part of Si or less, 0.5 part of Bi or less, 0.1 part of Se or less and the balance Zn. The alloy is resistant to magnetism, does not generate heat in the magnetic resonance imaging (MRI) process and does not generate metal artifact affecting imaging. In addition, the biomedical zinc alloy has good mechanical performance and biocompatibility. The zinc alloy not only is suitable for surgical implantation materials and medical instruments, but also can be used for preparing jewelries and other products often making contact with the human body.

Description

technical field [0001] The invention belongs to the field of alloys, and in particular provides a novel magnetically compatible zinc alloy material and its application. Background technique [0002] Magnetic resonance imaging (Magnetic Resonance Imaging, MRI) is a non-invasive examination, has become one of the indispensable imaging diagnostic methods in the current medical field. MRI has good soft tissue resolution, multi-plane, multi-parameter imaging technology, non-invasive and no X-ray radiation damage. [0003] The most obvious disadvantage of MRI clinically is that patients with metal implants, such as vascular stents, bone plates, artificial limbs, shrapnel, hemostatic chucks, etc., cannot be examined, because the movement or heating of metal foreign bodies may damage important organs and organs. Large blood vessels, and MRI metal artifacts produced by the metal itself also seriously affect the resolution of the image. In MRI examination, different materials have d...
