The present application relates to the technical field of nerve monitoring, in particular to an intraoperative real-time feedback system and method for sacral nerve stimulation, the system comprising: a biological motion sensing unit for real-time monitoring of the body surface contraction movement of the perineum and perianal area and foot movement through a sensor and generating corresponding multi-modal sensing signals; a processing unit for receiving the multi-modal sensing signals and performing synchronization and feature extraction, inputting the extracted features into a pre-trained machine learning model to obtain a judgment result representing the effect of sacral nerve electrode implantation target point and the accuracy of the target point position; a feedback unit for receiving the judgment result and converting it into feedback information for unified display. The present application realizes objective quantitative evaluation through multi-modal signal synchronous perception and fusion, as well as integrated machine learning model, provides intelligent and predictive feedback beyond simple threshold judgment, and realizes precise guidance of electrode implantation.

The embodiment of the utility model provides a sacral nerve stimulation electrode assembly and a guiding device. The sacral nerve stimulation electrode assembly comprises a stimulation electrode, a first limiting assembly and a second limiting assembly. Wherein the stimulating electrode is used for stimulating sacral nerves; the first limiting assembly is arranged on the stimulating electrode and located at the end, close to the target point, of the stimulating electrode. The second limiting assembly is arranged on the stimulating electrode, the first limiting assembly is located at the end, close to a target spot, of the stimulating electrode, and the second limiting assembly and the first limiting assembly are arranged oppositely or oppositely; the first limiting assembly and the second limiting assembly are used for limiting the stimulating electrode to move in the axial direction, and therefore the problem that the stimulating electrode is prone to displacement in subcutaneous tissue, and consequently the sacral nerve stimulating effect is poor is solved. The sacral nerve stimulation electrode assembly guiding device prevents the first limiting assembly and the second limiting assembly from structural deformation in the process of implanting a stimulation electrode.
