The utility model discloses a mushroom type tectorial membrane internal cytoskeleton for esophagus and stomach connecting. The utility model comprise a metal network tube with the upper and lower ports, and a medically-used macromolecule polymer membrane which covers the surface of the above-mentioned metal network tube; the mentioned upper port is horn-like, and the lower port mushroom-shaped; circular convex wall is arranged on the metal network tube between the upper ports and lower ports. The utility model is characterized in the use of new involved technology and the x-ray image for orientation. The membrane internal bracket which comprises of metal network tubes is arranged into the fistula lesions of the gastroesophageal inosculated parts so as to cure the fistulas by means of minimally invasive technique.
