Material used for medical implantation material

Abstract

The invention relates to a material for medical implantation material, which is composed of 15-20% of nano diamond and 80-85% of magnesium alloy or zinc alloy according to mass ratio, wherein the magnesium alloy is composed of 90-92% of magnesium, 2-8% of rare metals, 2-8% of zinc, 2-8% of aluminium and 2-8% of calcium according to mass ratio; and the zinc alloy is composed of 90-92% of zinc, 2-8% of rare metals, 2-8% of magnesium, 2-8% of aluminium and 2-8% of calcium. The material used for the medical implantation material can be absorbed by human body, and hidden trouble due to lifting of the material in human body can be avoided, or secondary operation required for taking the material out can be avoided. The medical implantation material is composed of 20% of nano diamond and 80% of zinc alloy according to mass ratio, wherein the zinc alloy is composed of 92% of zinc, 2% of rare metals, 2% of magnesium, 2% of aluminium and 2% of calcium according to mass ratio.

Description

technical field [0001] The invention relates to a material for medical implants. Background technique [0002] In medical technology, the material of implants (including vascular stents, bone screws, etc.) is very important. Most of the current implants are made of non-absorbable metal. Since the metal is not degradable, it is easy to stay in the body and cause blood clots, or a second operation is required to remove the implant, causing secondary damage to the patient. Contents of the invention [0003] In order to overcome the above-mentioned shortcomings of the prior art, the object of the present invention is to provide a material for medical implants, which is easily absorbed and degraded in vivo, and meets the requirements of mechanical strength and mechanical support time. [0004] In order to achieve the above object, the technical scheme adopted in the present invention is: [0005] A material for medical implants, which consists of 15% to 20% by mass of nano-di...
