23 Jul Tissure engineering peripheral nerve graft
Abstract
The utility model discloses a tissue engineering ambient nerve graft for providing a surgical graft for repairing nerve coloboma, which has wide application scope and good quality. The tissue engineering ambient nerve graft of the utility model comprises a bracket for being connected with two broken ends of nerves and a seed cell with the function of promoting nerve regeneration, wherein the seed cell is attached to the bracket, forming a compound body provided with a stimulated nerve three-dimensional structure and biologic activity. The bracket has a beam-shaped microfilament structure which is composed of microfilament and is prepared by biodegradation material. A layer of film is coated on the outer surface of the bracket, forming a tubular bracket. The seed cell is a class permitting cell formed by means that an adult stem cell is induced outside the body. The utility model is the tissue engineering ambient nerve graft in real meanings. A biochemistry stimulating channel is provided for regenerated nerve fibers to pass through a nerve coloboma region. In addition, the inside seed cell has promoting function on the nerve regeneration. Therefore, the utility model can be used for repairing nerve coloboma with a long distance. A nerve repairing effect is notably enhanced, and a clinic application range is wide.
