在血管中铺设“光纤” 实现患肢运动功能修复 我科学家团队取得介入式脑机接口新进展

Core Insights - The article discusses a groundbreaking intervention in brain-machine interface technology that has enabled a 67-year-old patient to regain motor function 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%, significantly improving recovery efficiency compared to traditional invasive methods that require craniotomy [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 [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 by promoting synaptic regeneration through synchronized electrical stimulation training [2]. - Clinical trial data indicates that patients have regained 82% of their grip strength compared to their healthy side, showcasing the effectiveness of the technology [2]. - The team has established the "Interventional Brain-Machine Information Technology Research Institute" to focus on the development, clinical validation, and commercialization of brain-machine interface technology [2].
