"Internal hemorrhoid" affects the quality of life due to hemorrhage and prolapse as a common and frequently-occurring disease. Endoscopic sclerosing agent injection has replaced traditional surgery and become the most commonly used treatment method in developed countries. At present, how to reduce the side effects of sclerosing agent and accurately determine the injection site and depth has become a difficult clinical problem. The research group creatively put forward the theory of foam sclerosing agent to treat internal hemorrhoids in the early stage. With the aid of transparent cap, the visibility of surgical field of vision can be improved. The mini probe ultrasound (MPS) is proposed to effectively evaluate the submucosal in
