23 Jul Tracheal stent and application thereof
Abstract
The invention relates to a tracheal stent and application thereof. The tracheal stent comprises supporting rings and a supporting connecting rod, wherein the various supporting rings are of C-shaped structures and are serially connected by virtue of the supporting connecting rod, so that the various supporting rings are integrally fixed with the supporting connecting rod. The invention further provides a tissue engineering trachea, and the tissue engineering trachea is prepared by winding a chondrocyte-gelatin/polycaprolactone electrospun membrane complex on the outer surface of the tracheal stent. The tracheal stent or the tissue engineering trachea disclosed by the invention can be used for repairing tracheal stenosis by virtue of a tracheal external support suspension method, and a new C-shaped cartilaginous ring is formed after the implantation of the tracheal stent or the tissue engineering trachea, so as to guarantee growth potential finally.
