脑机接口新突破！闭环脊髓神经接口治疗助患者自主行走

Core Viewpoint - The successful implantation of the "closed-loop spinal cord nerve interface" at Zhejiang University Second Hospital marks a significant technological breakthrough in the field of spinal cord nerve interfaces and neural function remodeling in China, offering new hope for patients with spinal cord injuries [1][3][5]. Group 1: Patient Case Study - The patient, referred to as Mr. Jin, is a 61-year-old man who suffered a complete spinal cord injury due to a fall, resulting in significant mobility impairment and loss of bowel and bladder control [3]. - After undergoing the "closed-loop spinal cord nerve interface" surgery in March 2025, Mr. Jin showed remarkable recovery, achieving the ability to perform various daily activities, including walking, turning, and climbing stairs [3][5]. - The surgical procedure involved the implantation of a spinal cord stimulation electrode with 16 contact points and a wireless rechargeable stimulator, both of which are products with complete independent intellectual property rights from China [3][5]. Group 2: Technological Advancements - The new technology focuses on enhancing the patient's spinal cord function recovery by utilizing specific stimulation contact combinations and precise stimulation frequencies and intensities, along with closed-loop electromyographic feedback [5]. - The success of this surgery indicates the potential for not only improving motor functions but also promoting the repair of neural sensory pathways, as evidenced by the patient's gradual recovery of sensory functions and improved quality of life [5]. Group 3: Future Implications - The successful operation provides hope for approximately 3.7 million spinal cord injury patients in China, with plans for further clinical research and recruitment of clinical trial participants to explore new treatment pathways for nerve damage repair [5]. - The hospital aims to continue interdisciplinary collaboration and innovation in the application of brain-machine interface technology, which is considered a disruptive frontier technology [5].
