Three dimensional parts of polissacaru00cddeos, dense and ru00cdgidas, and their method of obtaining

摘要

This invenu00c7u00c3o refers to parts of polissacaru00cddeos three-dimensional, in particular, chitosan, dense and ru00cdgidas with different geometries, and their method of obtaining, preferably for applications biomu00c9dicas.The method consists in the solution of raw material, a polu00cdmero appropriate, in aqueous solutions appropriate, followed by the freezing of solutions obtained in molds and subsequent placement of these, already frozen, a precipitant solution appropriate to the precipitate, giving Leaving them a look solid.The final steps include neutralisation, if appropriate, washing and drying the resulting product. This can be machined so as to give it the proper implant geometry, i.e., the three-dimensional parts.Among the various potential applications biomu00c9dicas that can be exploited using the innovative method presented are the devices for setting internal reabsorvu00cdveis used for the union of fractures u00d3sseas.
