The invention provides a compound active
amnion material, a preparation method and application thereof and a compound active
amnion uterine cavity repair
stent. The preparation method comprises the following steps: (1) providing a
collagen sponge prepare liquid or a compound
collagen sponge prepare liquid; (2) providing an
amnion with both an epithelial layer and a
basement membrane; (3) pouring and
coating the prepared prepare liquid on the
basement membrane of the amnion to enable the
basement membrane and the prepare liquid to be subject to crosslinking, and then preparing the compound active amnion material through
freeze drying. The compound active amnion material not only keeps the complete structure and the due biological function of the amnion but also endow the amnion with a certain rigidity, so that the compound active amnion material has stronger maneuverability in application after TCRA (Transcervical Resection Of Adhesions) operation; the compound active amnion
uterine cavity repair
stent integrates the compound active amnion material and a
saccule at the front end of a
pipe body, the
saccule expands under the action of an external force to
push out the compound active amnion material, and then the compound active amnion material is successfully attached to the inner wall of the
uterine cavity; the
stent is convenient to take out and prevents secondary damage.
