The invention provides a complex
hernia patch and a preparing method and application thereof. The complex
hernia patch comprises three layer structures which are an outer biological layer, an inner supporting layer and an outer biological layer from bottom to top respectively, wherein the outer biological
layers are accellular
stent layers, and the inner supporting layer is a
polypropylene mesh layer. The complex
hernia patch prepared through the preparing method comprises the three layer structures, accellular stents in contact with tissue are located on the outer
layers, cells can be induced to grow, and thus infection of a hernia
coloboma part and formation of
scars can be reduced; the
polypropylene mesh layer serves as the inner supporting layer so that the
mechanical strength of the complex hernia patch can be maintained, the stability of the patch can be improved, and high
abdomen expansion pressure can be borne; furthermore, the
binding force of the inner layer and the outer layers is good, and thus the problems that due to the fact that the strength of an existing product is not stable, high
abdomen expansion pressure cannot be borne, a
stent is gradually degraded after cells grow into the
stent, consequently tardive pain of
hernia repair is brought and relapse is likely to occur can be effectively solved; in addition, the preparing method is simple and capable of being applied to industrial production.
