Abstract
Description
technical field
[0001] The invention relates to a composite slow-release artificial nerve guide material and preparation technology for repairing and regenerating human nerve damage. Background technique
[0002] Peripheral nerve injuries and defects are common in clinical practice, so far, the therapeutic effect is not satisfactory. How to improve the curative effect is still an important issue that needs further research.
[0003] The main problems affecting nerve repair and regeneration are limited sources of transplanted nerves, damage to the donor site, slow nerve regeneration, and poor regeneration quality. There have been many studies on nerve substitutes in the past, including autologous blood vessels, muscles, tendons, fascia, and synthetic non-absorbable and absorbable nerve bridge catheters. These materials and methods have achieved different therapeutic effects in animal experiments, and some materials have been used in clinical research reports. But in genera...
