| titleOfInvention | A kind of novel nano tunica fibrosa/yarn count frame for graft of trachea and preparation method thereof |
| abstract | The present invention relates to a kind of novel nano tunica fibrosa/yarn count frame for graft of trachea and preparation method thereof.Novel nano tunica fibrosa/yarn count the frame is interior outer double-layer structure, and internal layer is nano fibrous membrane, and outer layer is nano fibre yarn.Preparation flow includes preparing nano fibrous membrane, prepare nanometer yarn and preparing nano fibrous membrane/nanometer yarn tubular bracket.The nano fibrous membrane and the raw material of nanometer yarn of preparing is PCL lactate.The method for preparing nano fibrous membrane is high-voltage electrostatic spinning technology, and the method for preparing nanometer yarn is dynamic liquid electrostatic spinning technique.Novel electrostatic weaving nano fibrous membrane/yarn double-layer scaffold for graft of trachea of the present invention, sticking and breed beneficial to cell, grow along nanometer yarn fiber alignment beneficial to cartilage cell, for building transplantable tissue engineering trachea, can be used as trachea defect repairing, to promoting tunica mucosa tracheae reparation and clinical reconstruction trachea defect, reduction to rebuild tracheae postoperative complications and provide significant reference. |
