Abstract

The invention provides a material with excellent biological activity for preparing an artificial joint.The material is prepared from, by mass, 40-60 parts of silicone rubber, 10-20 parts of collagen, 1.5-4 parts of vinyl silicone oil, 20-32 parts of fumed silica and 0.8-3 parts of calcium hydroxide.The material has excellent biological activity, biocompatibility and osteoconduction which are superior to biomedical titanium and silicone rubber, the strength is high, and the mechanical property is good.

Description

technical field [0001] The invention relates to the field of medical supplies, in particular to a material for preparing artificial joints and a preparation method thereof. Background technique [0002] Artificial joint is an artificial organ designed by people to save joints that have lost their function. It has the best curative effect among artificial organs. Generally speaking, its service life can reach more than 20 years. With the advancement of science and technology, artificial joint surgery has become a very successful and sure operation: it can immediately eliminate joint pain, restore normal joint activity and function, and enable people who have suffered from joint pain for a long time to gain new life. Like normal people, walking, climbing stairs, going out for travel, going out to work, shopping and physical exercise. [0003] The metal parts of artificial joints were once made of stainless steel, and later cobalt alloy materials were developed. Cobalt alloys...
