Energy-Providing Bone-Repair Degradable Porous Scaffold, Preparation Method Thereof, and Application Thereof

A method for preparing an energy-providing bone-repair degradable porous scaffold, comprising the following steps:

• (1) mixing a polyatomic acid and derivatives thereof, a dibasic alcohol and derivatives thereof, and a tribasic alcohol and derivatives thereof by a molar ratio of 1:x:(1−x), with x between 0 and 1, reacting under stirring at 100-160° C. for 0.5-3 hours, adding an entrainer once in a while, continuing the reaction under a vacuum degree from −80 kPa to −95 kPa for 0.5-10 hours, collecting the products, and adding a polar solvent to make up a first solution of 1-50 wt %;
• (2) adding a diisocyanate cross-linking agent at an amount of 0.01-0.2 mL per milliliter of the first solution, reacting at 50-100° C. for 0.1-1 hour, adding a gelatin solution of 1-50 wt % and well-mixing to obtain a second solution, wherein the added gelatin solution is 0.1-10 times as volume as the first solution;
• (3) adding a pore-forming agent with a diameter of 100-900 μm into a mould, and pouring the second solution obtained in step (2) into the mould;
• and
• (4) removing the pore-forming agent after curing, and obtaining a porous scaffold by using a drying method,
• wherein, the polyatomic acid and derivatives thereof are one or more selected from succinic acid, citric acid, isocitric acid, fumaric acid, malic acid, cis-aconitic acid, ketoglutaric acid and oxaloacetic acid;
• the dibasic alcohol and derivatives thereof are one or more selected from glycol, glycol diacetate, butanediol, propanediol, hexanediol and poly(ethylene glycol);
• and the tribasic alcohol and derivatives thereof are one or more selected from glycerine and glycidol.
