This invention discloses an intelligent bionic artificial anus system, comprising: a sphincter module, a pressure sensor, and a controller. The pressure sensor and controller are disposed within the sphincter module. The sphincter module is located on the outer side of the human intestine and constricts the intestine. The pressure sensor detects a first pressure emanating from inside the intestine and sends the first pressure value to the controller. The controller issues an opening command when the first pressure value meets a first condition. The sphincter module reduces the external pressure applied to the intestine based on the opening command, causing the intestine to open. The controller issues a closing command when the first pressure value meets a second condition. The sphincter module closes the intestine based on the closing command. This allows patients who have had their anus removed to regain anal function, enabling them to defecate, work, live, and exercise normally without the need for a stoma, thus improving their quality of life.
