China unveils world’s first germ resistant titanium-copper medical implant

China has unveiled the world’s first copper-blended titanium implant for orthopaedic surgery after more than a decade of research and development.

This innovative material retains the exceptional strength and hardness characteristic of titanium alloy medical devices while significantly reducing the risk of post-operative infection, according to its developers.

On April 21, the world’s first bone pin made using the material was approved for market release by China’s National Medical Products Administration.

The device was developed through a collaboration between Silvan Medical, a Suzhou-based medical device firm, and the Shenyang-based Institute of Metal Research, an affiliate of the Chinese Academy of Sciences.

According to an article published on the institute’s website in late April, the product’s release “marks the successful transition” of copper-titanium alloys from research to clinical application.

Titanium and its alloys are widely used in dental implants, hip and knee replacements, bone plates and screws due to their robust mechanical properties, excellent corrosion resistance and optimal biocompatibility.

Among these, bone pins are some of the most essential devices and are used to fix fractures.
