Abstract： |
The present invention relates to a hydrogel material for repairing central nerve and its preparation method. Said method includes the following steps: using hyaluronic acid as main component, making it and one or several high-molecules implement copolymerization reaction to obtain porous frame material, preparing preformed material, mixing them and freeze-drying, covalently cross-linking, ultrasonic cleaning and freeze-drying so as to the invented hydrogel frame material. In the hydrogel frame material one or several kinds of substances of growing factor, cell and protein can be added. |
