The invention provides a therapeutic apparatus provided with submucous implanted electrodes and capable of automatically sensing alimentary tract successive pacemaking. The therapeutic apparatus comprises an implanted system controller, multiple sensors used for detecting activities of an alimentary tract, multiple implanted electrodes and an in-vitro system controller, wherein the signal inlet end of the implanted system controller can be connected with the sensors used for detecting the activities of the alimentary tract; and the signal output end of the implanted system controller is connected with the implanted electrodes. The therapeutic apparatus can be used for receiving a group or multiple groups of signals input by the multiple sensors; the group or multiple groups of signals are analyzed by virtue of the implanted system controller so as to recognize a specific state of the alimentary tract; and the implanted system controller outputs multiple groups of stimulation signals output by the one or multiple implanted electrodes by virtue of one or multiple signal generators, and the stimulation signals are used for stimulating muscles around each implanted electrode to finish contractile activity. The therapeutic apparatus can be implanted into a patient and stayed in the patient for a long time, and can be used for generating one or more groups of successive simulation signals according to the motion state of the alimentary tract of the patient and stimulating the alimentary tract to recover to a normal physiological status.
