中新网天津8月16日电 (孙玲玲 丛敏)记者16日从南开大学获悉，日前，全球首例介入式脑机接口传感器血管内取出试验在北京获得成功。该试验由南开大学医学院副院长、人工智能学院段峰教授团队牵头，试验首次将介入式脑机接口传感器及无线传输模块安全取出，标志着介入式脑机接口技术的安全性有了重要提升，为该技术的临床应用提供了坚实保障。
2023年5月4日，段峰教授团队牵头完成了全球首例非人灵长类动物介入式脑机接口试验，实现了介入式脑电信号从被动采集到主动控制的技术飞跃，突破了血管内脑电信号采集、介入式脑电信号识别等核心技术。据悉，本次试验是在此基础上取得的进一步成果。
试验中，研究人员将无线传输设备植入实验动物皮下，并将采集到的介入式脑电信号通过无线传输设备传出，实现了稳定、高效的信号传输；同时，通过介入手术将先前导入羊颅内血管壁上的介入式脑机接口传感器安全取出。
段峰教授表示，此次试验不仅在脑机接口技术研究方面取得了重要进展，而且展示了介入式脑机接口在安全性和应用上的巨大潜力。无线传输技术的应用将帮助介入式脑机接口系统变得更加便携和易用，通过识别运动皮层脑电信号控制康复运动辅助机器人工作，为脑卒中、脑损伤、截瘫等运动功能障碍患者带来福音，大大提升患者的生活质量。
段峰教授还指出，未来，这项技术将通过“医工结合”打造高端医疗设备民族品牌，为脑疾病医疗康复领域带来广阔的市场前景和深远的社会效益。

BEIJING, Aug. 16 (Xinhua) — A brain-machine interface sensor was successfully extracted from a patient’s blood vessels in a groundbreaking trial in Beijing, marking a significant step forward in the safety and clinical application of the technology, according to a report from Nankai University on Tuesday.
The trial, led by Professor Duan Feng’s team from the School of Medicine and the College of Artificial Intelligence at Nankai University, was the first of its kind to safely remove an implantable brain-machine interface sensor and its wireless transmission module. This achievement represents a crucial advancement in the safety of vascular brain-machine interface technology, providing a solid foundation for its clinical use.
On May 4, 2023, Duan’s team conducted the world’s first non-human primate vascular brain-machine interface experiment, achieving a technological leap from passive to active control of invasive electroencephalography (EEG) signals. The breakthroughs included core technologies such as vascular EEG signal acquisition and invasive EEG signal recognition.
This latest trial is a further development based on the previous work.
During the experiment, researchers implanted a wireless transmission device under the skin of the experimental animal and transmitted the collected invasive EEG signals via the wireless device, achieving stable and efficient signal transmission. Additionally, the invasive brain-machine interface sensor previously placed on the vascular wall of the sheep’s skull was safely extracted through surgical intervention.
Duan noted that the trial not only made important progress in the research of brain-machine interface technology but also demonstrated the great potential of vascular brain-machine interfaces in terms of safety and application. The application of wireless transmission technology will make the vascular brain-machine interface system more portable and user-friendly, allowing for the control of rehabilitation and movement assistance robots by identifying brain signals from the motor cortex, bringing hope to patients with conditions such as stroke, brain injury, and paraplegia, significantly improving their quality of life.
Duan also pointed out that in the future, this technology will contribute to the creation of a high-end medical equipment brand through “medical-engineering integration,” bringing a broad market outlook and profound social benefits to the medical rehabilitation field for brain diseases.
