According to the National Healthcare Security Administration, the world's first invasive brain computer interface medical device has been officially approved for market launch recently. Only two days after its launch, the National Healthcare Security Administration completed the medical insurance coding for the product, successfully bridging the key link from approval to clinical application of the innovative product. With rapid breakthroughs in technologies such as neural signal processing, biomaterials, and artificial intelligence, brain computer interfaces are gradually moving from sci-fi concepts to clinical applications. By decoding brain electrical signals, precise interaction between the human brain and external devices is achieved, providing a new rehabilitation path for patients with functional impairments such as movement, sensation, speech, and neurological disorders. The "Implantable Brain Computer Interface Hand Motor Function Compensation System" approved this time is mainly aimed at patients with high paraplegia caused by spinal cord injury. These patients suffer from spinal cord damage that connects the brain and limbs, resulting in complete loss of hand function and even lifelong paralysis. Rehabilitation is extremely difficult, and the burden of family care is heavy. At present, there are over 3.7 million spinal cord injury patients in China, and the number is increasing at a rate of about 90000 per year. This product implants a coin sized minimally invasive device into the patient's skull, which can collect and decode real-time EEG signals, allowing patients to control external pneumatic gloves with their "mind" and independently complete daily actions such as grasping, retrieving items, and drinking water. After only one month post surgery, patients can achieve home autonomous operation. This breakthrough provides a new 'Chinese solution' for the world-class medical challenge of spinal cord injury repair. (New Society)
