23 Jul Biodegradable macromolecule urethra repairing support and preparation method thereof
Abstract
The invention discloses a biodegradable macromolecule urethra repairing support. The biodegradable macromolecule urethra repairing support is characterized by being a tissue engineering support with a tubular appearance shape and being prepared from macromolecular materials which can be completely biodegraded, the support is soft and has toughness, the microstructure of the support is a porous three-dimensional space, the average pore size is 20-200 microns, the support has good biocompatibility, and cells can be planted. The invention also discloses a preparation method of the biodegradable macromolecule urethra repairing support. The prepared urethra repairing support shows certain rigidity and necessary toughness, can endure strong tensile force, and is conducive to restoration of the shape of the support when being extruded and has good biocompatibility, and urethra mucous epithelium cells can be adhered and propagated on the support. According to the prepared urethra repairing support, residual of organic solvents and pore-foaming agents sare avoided, biological assessment is safer, a preparation process is simpler and more convenient, cost is lower, and the prepared urethra repairing support is more applicable to clinical application.
