23 Jul Tissue engineering ambient nerve graft
Abstract
The utility model discloses a peripheral nervous graft of tissue engineering which aims to provide a surgery graft with wider applicability and better quality to repair the nerve defect. The utility model comprises a bracket used for connecting the two broken ends of the nerve, and seed cells which have the functions of accelerating the nerve to regenerate, wherein the seed cells are attached on the bracket to form a composite body which is in a three-dimensional structure of imitating nerve and has bioactivity, the bracket is a variant nerve without cells, and the seed cells are adult stem cells. The utility model is a peripheral nervous graft of tissue engineering with a genuine meaning. The utility model not only provides a biochemical imitation path for the regenerated nerve fiber to pass through the nerve defect area, but also the seed cells in the peripheral nervous graft have the promotion effect on the nerve regeneration. Thus, the nerve defect with longer distance can be repaired by the utility model, and the nerve repairing effect is greatly improved. Therefore, the clinical application range of the utility model is wider.
