  • Patent number: 11969521
    Abstract: A bone-regeneration material that contains calcium phosphate particles in a biodegradable fiber containing PLGA by using electrospinning. A PLGA resin is heated in a kneader to soften until the viscosity of the resin becomes 102 to 107 Pa·s. A powder of calcium phosphate fine particles is added and mixed with the softened PLGA resin, while the blade of the kneader rotates. The mixture is kneaded by applying thermal and mechanical energy to the mixture through the continuous rotation of the blade of the kneader in the heated state, and aggregations of the calcium phosphate fine particles are disintegrated to prepare a composite in which the calcium phosphate fine particles are dispersed in the PLGA resin. The composite is dissolved in a solvent to prepare a spinning solution. Electrospinning is performed on the spinning solution to manufacture biodegradable fibers having therein the calcium phosphate fine particles substantially uniformly dispersed.

  • Publication number: 20240093409
    Abstract: A method for producing a cotton-wool like material for bone regeneration using a wet spinning method. 50-80 wt % of calcium salt particles and 50-20 wt % of PDLLGA resin are put into a mixing vessel, dissolved in acetone, and stirred to produce a spinning solution with a resin concentration of 10-20 wt % in which said calcium salt particles are dispersed. The produced spinning solution is filled in a syringe, and the spinning solution filled in the syringe is injected into a collector container filled with poor solvent by extruding the spinning solution from the discharge port of an injection needle having a predetermined diameter. The spinning solution injected into the poor solvent is solidified into fibers by interdiffusion of desorption of organic solvent and penetration of poor solvent in the poor solvent solution. The fibers solidified in the poor solvent are deposited in a floating state in the collector vessel without fiber-to-fiber adhesion and collected in a cotton-wool like shape.
