The application provides a cerebral apoplexy postoperative sign monitoring system, which is fused with a nerve motor function evaluation wristband and a head-mounted brain electrical impedance dynamic imaging device, and breaks through the blind area of postoperative monitoring. The wristband device collects upper limb electromyographic signals and joint motion mechanics parameters through a microneedle electrode array and a distributed piezoresistive sensor, drives a neural network to output a standardized motor score based on time-frequency domain features containing electromyography, joint angle, trajectory smoothness and grip force change rate, and is related to a clinical Fugl-Meyer scale; the imaging device adopts a multi-ring electrode array and an improved D-bar algorithm to reconstruct a brain electrical conductivity distribution map, constructs a multi-level decision tree early warning model by extracting impedance change rate Delta Z, spatial gradient entropy SGE and hemisphere asymmetry Asym, and realizes brain edema detection. Through multi-modal data fusion and minute-level response, the system solves the fragmentation problem of postoperative monitoring and provides precise decision support for cerebral apoplexy rehabilitation.

The application discloses a kind of stimulating electrodes for nerve motor function recovery after spinal cord injury, including catheter, stimulating electrode piece and guide wire;The cross section of the catheter is rectangular, two stimulating electrode pieces are a group, and a plurality of stimulating electrode pieces are arranged at fixed distance on the catheter, and each group of stimulating electrode pieces is arranged on the both sides outside the catheter respectively, and each stimulating electrode piece is connected with the outside by connecting the corresponding guide wire arranged in the catheter respectively;Soft barb is arranged above the same side of each stimulating electrode piece in the catheter.The stimulating electrode for nerve motor function recovery after spinal cord injury of the utility model is suitable for the electrical stimulation treatment of upper and lower limb motor dysfunction after spinal cord injury, can be applied to patients of different ages, and can effectively continuously stimulate the specific nerve root motor bundle of patient, with good curative effect.
