Description

Technical Field

[0001] The present invention belongs to the technical field of artificial human organs, and particularly relates to an artificial anus device. Background Art

[0002] The Miles operation for rectal cancer (abdominoperineal resection for rectal cancer) is the preferred surgical method for most low rectal cancers and is an important part of colorectal cancer surgery. Since the tumor is located too low, the anus has to be removed, and an intestinal ostomy bag structure is adopted. The intestinal ostomy bag cannot control the leakage of intestinal contents. The traditional solution is for the patient to carry the intestinal ostomy bag with them. On the one hand, because the intestinal ostomy bag is pasted on the abdominal wall, there is a risk of falling off or causing wound infection. On the other hand, fecal water flows out of the artificial anus randomly, causing great inconvenience to the patient's life and bringing psychological problems to the patient, resulting in social phobia. Moreover, the intestinal ostomy bags currently used in clinical practice only have the simplest function of collecting contents and lack an intelligent device with good control.

[0003] To solve the above problems, the currently applied artificial anus devices mainly have the following three methods: The shape memory alloy artificial anus sphincter (patent application number: 01121110.5) has a simple structure and is simple and convenient to use. However, the shape memory alloy needs to be heated to produce deformation, which will cause burns to the intestinal tissue and there are safety problems when used in the human body. The artificial pubic sphincter device (patent application number 201811318671.7) scientifically uses the bionics method, but it has poor control over solid feces, and the mechanical device is too complex, and the intestinal clamping may cause intestinal necrosis and easily lead to intestinal obstruction.
