The world's first intravascular removal experiment of an invasive brain-computer interface sensor was successfully completed in Beijing a few days ago. The experiment was led by the team of Duan Feng, vice dean of the School of Medicine of Nankai University and professor of the School of Artificial Intelligence, and was jointly completed with the Air Force Specialty Medical Center of the People's Liberation Army, the General Hospital of the People's Liberation Army, Shanghai Xinwei Medical Technology Co., Ltd., and Kunshan Hangjin Intelligent Technology Co., Ltd. They safely removed the invasive brain-computer interface sensor and wireless transmission module for the first time, marking an important improvement in the safety of invasive brain-computer interface technology and providing a solid guarantee for the clinical application of the technology.

In recent years, Duan Feng's team has been deeply engaged in the field of interventional brain-computer interface research and has made many important advances. The content of this experiment includes implanting wireless transmission equipment under the skin of experimental animals, and transmitting the collected interventional EEG signals through the wireless transmission equipment, achieving stable and efficient signal transmission; and safely removing the interventional brain-computer interface sensor previously introduced into the wall of the sheep's intracranial blood vessels through interventional surgery. The whole process is carried out under the guidance of DSA (digital subtraction angiography), ensuring the safety of the surgical process.

During the experiment, the experimental animals did not show any rejection reaction and remained healthy after the interventional brain-computer interface sensor was removed. It is reported that the success of this experiment not only verified the safety and biocompatibility of the wireless transmission equipment and the interventional brain-computer interface system, but also verified that the interventional brain-computer interface sensor can be safely removed without damaging brain tissue and blood vessels, providing a solid foundation for the future clinical application of interventional brain-computer interface technology.

Duan Feng introduced that this experiment not only made important progress in the research of brain-computer interface technology, but also demonstrated the great potential of interventional brain-computer interface in terms of safety and application. The application of wireless transmission technology will help the interventional brain-computer interface system become more portable and easy to use. By identifying the electroencephalogram signals of the motor cortex to control the work of the rehabilitation movement assisting robot, it will bring good news to patients with motor dysfunction such as stroke, brain injury, paraplegia, and greatly improve the quality of life of patients.
