Core Insights - The article discusses a groundbreaking intervention in brain-machine interface technology that has enabled a 67-year-old patient to regain movement in his paralyzed arm after a stroke, marking a significant advancement in rehabilitation methods [1][2]. Group 1: Technology and Innovation - The intervention involves a minimally invasive procedure where a 2mm electrode stent is implanted into the brain's motor cortex via the neck's blood vessels, establishing a "brain-machine-limb" closed-loop system [1]. - The system boasts a signal transmission stability rate of 99.7%, allowing patients to perform hand movements through thought within two weeks post-surgery [1]. - The technology integrates several innovations, including a bionic spider-web structure electrode that adapts to vascular pulsation, a self-designed wireless power supply platform with over five years of battery life, and an intelligent adaptive decoding algorithm that adjusts output parameters in real-time based on the patient's intentions [1][2]. Group 2: Clinical Applications and Research Development - The research team has introduced a "central-peripheral-central" neural reconstruction model that enhances motor function recovery efficiency through synchronized electrical stimulation training, with patients achieving 82% grip strength recovery compared to their healthy side [2]. - The team has conducted extensive research over several years, including experiments on sheep brains and non-human primates, laying a systematic foundation for human clinical trials [2]. - A new research institute focused on brain-machine interface technology has been established in collaboration with regional innovation centers, aiming to advance the development and clinical validation of this technology [2].
