The application discloses a brain electric wire fixing band after intracranial electrode implantation, which effectively solves the problem of inconvenient wire fixation after operation of the patient with implanted electrodes; the brain electric wire fixing band comprises a winding band, a fixing ring is arranged at the left free end of the winding band, the winding band is in a circular ring shape and the right free end of the winding band penetrates through the fixing ring, a positioning air bag is fixed to the inner side of the winding band, connecting rings are respectively fixed to the left and right sides of the upper end of the winding band, a pressing band in the up-down direction is fixed to the middle part of the winding band, two anti-pressure air bags are fixed to the upper end of the winding band and are located between the two connecting rings, the pressing band is located between the two anti-pressure air bags, an inflation device is fixed to the right end of the winding band, the left end of the inflation device is communicated with the positioning air bag through a main air pipe, the upper side of the inflation device is communicated with the right anti-pressure air bag through a secondary air pipe, and the two anti-pressure air bags are communicated through a connecting pipe; the structure is simple, convenient to operate, novel in design and high in practicability.

This invention discloses an implantable closed-loop neuromodulation system and method, relating to the field of neuroengineering, aiming to solve the problems of poor electrode adaptability and slow closed-loop response in existing implantable neuromodulation systems. The system includes intracranial electrodes, a one-to-one matching adapter plate for adapting different electrodes, a feedthrough component, and an implantable host fixed to the skull surface. The processing unit within the host decodes neural signals in real time within 10 ms to determine the brain state; if an abnormality is detected, the stimulation output unit selects a pattern from a preset safe stimulation pattern library to generate stimulation commands for intervention. This application achieves multi-electrode adaptation through the adapter plate and millisecond-level closed-loop response through high-speed processing, improving the timeliness and accuracy of intervention and enhancing safety.
