New technique for regenerating nerves

Engineers at Sheffield University (UK) in cooperation with the Laser Institute Zentrum Hannover (Germany) have announced a new method to help severely damaged nerves recover naturally, increasing the chances of recovery. sensation and movement in injured muscle areas.

This method uses a state-of-the-art medical device called the " Nerve Guidance Conduit".

Through CAD / CAM (computer aided design / manufacturing), a design and production program with the support of computers, the team can use lasers to create sophisticated tubes.

"Unlike spinal nerves, the nerves in the extremities are able to recover when damaged. However, this process requires support. We are designing and implanting a framework with can bridge at damaged sites, and provide a variety of physical and chemical support to promote this process, ' said John Haycook, professor of biological engineering at the University said Sheffield.

This new type of pipe is made of biodegradable synthetic resin from polylactic acid. It is designed to help damaged nerves regenerate through a series of small grooves.

After the nerve has completely regenerated, this duct will biodegrade gradually.

The team hopes this new method, published in the journal Biofabrication, will significantly improve the ability to restore various peripheral neurological injuries.

Currently, when the nerves in the limb are severely damaged, the patient loses the feeling and mobility in that limb. Traditional treatment is surgical intervention to stitch together nerve endings. However, this method usually does not bring about a complete recovery.
