23 Jul Design and application of multilayer tissue engineering tracheal scaffold based on 3D printing and electrospinning technology
Abstract
The invention relates to the design and application of a multilayer tissue engineering tracheal scaffold based on 3D printing and electrospinning technology. The design and application of the multilayer tissue engineering tracheal scaffold based on 3D printing and electrospinning technology comprise an outer layer scaffold, an inner layer scaffold and a reinforcing ring. The outer support is of arectangular grid structure; the inner layer support is of a rhombic grid structure; The inner layer bracket pair is arranged in the outer layer bracket, the inner and outer two layers of grids are staggered with each other, and a gap is arranged between the two layers of grids. The gap is used for placing an electrospun film loaded with a substance P; the reinforcing ring is arranged on the outerbracket. Its advantages are as follows: Combining 3D printing technology and electrospinning technology, a multilayer tissue engineering tracheal scaffold was constructed, which can be used to preparetissue engineering tracheal scaffold with physiological structure, and it is expected to improve the survival status of the host and the therapeutic effect of tissue engineering tracheal transplantation.
