End structure of transgastrointestinal endoscope coprophilous fungus transplantation injection catheter

The end portion of the end, extending into the body, of the catheter is a closed end, an annular groove A is formed in the outer surface of the side wall, close to the closed end, of the catheter, and a thin pipe coaxial with the catheter is formed at the bottom of the annular groove A; one end of the outer side wall of the thin pipe is uniformly provided with a plurality of liquid outlet holes communicated with an inner hole of the guide pipe by taking the axis of the guide pipe as the center, and the other end of the outer side wall of the thin pipe is provided with convex plug bodies matched with the liquid outlet holes in positions corresponding to the liquid outlet holes; and when the convex plug body is fixedly connected with the liquid outlet hole, the thin tube is bent and folded towards the inner hole of the catheter. According to the structure, the end structure of the transgastrointestinal endoscope coprophilous fungus transplantation injection catheter ensures that the inner hole of the catheter i
