The invention discloses a three-dimensional porous
stent. The three-dimensional porous
stent is made from composite biomaterials consists of degradable natural biomaterials and degradable artificiallysynthesized
macromolecule materials. The three-dimensional porous
stent has a three-dimensional orderly porous structure in which holes are homogeneous, mutually penetrated and regular in distribution, and the hole
diameter is 80-350[mu]m. The invention further discloses a preparation method and application of the three-dimensional porous stent. According to the method disclosed by the invention,the advantages of an
emulsion microflow control technique and the advantages of the composite biomaterials are combined. The three-dimensional porous stent disclosed by the invention has favorable
biocompatibility and biodegradability and has the characteristics that the hole
diameter is appropriate, the holes are mutually penetrated, and the three-dimensional porous stent is degradable and compressible, can be shaped and can be used for performing drainage effectively, and good space is provided for
medicine delivery and slow release,
cell growth and
metabolism and
tissue repair; the proportion of ingredients of the compound materials and the holes in concentrated distribution can guarantee that the three-dimensional porous stent has favorable compression and resilience properties like
sponge, so that the three-dimensional porous stent can better adapt to the shape of the
uterine cavity or the shape of other positions needing prevention of adhesion, and the effect of effectively preventing the adhesion can be achieved.
