23 Jul Artificial trachea
Abstract
The utility model relates to an artificial trachea, which belongs to a bio-medicine and particularly relates to the technical field of an artificial tissue engineering trachea. The utility model is characterized in that the artificial trachea is supported by a net-shaped circular tube which is formed by weaving polydioxanone and is analogous to the trachea, the outer surface of the net-shaped circular tube is covered with a film consisting of a small intestinal submucosa inner layer, and the outer surface of the film and the inner surface of the circular tube are covered with collagen coatings. The embodiment of the utility model has the advantages that certain mechanical strength and processing performance are provided for a thoracic trachea operation, an appropriate environment can be provided for cell growth and tissue regeneration, and the artificial trachea has good biocompatibility and degradability, plays an important role of inducing and facilitating tissue regeneration and repair, and is a tissue engineering trachea convenient for support.
