Technical Breakthrough: Robotic System Achieves Non-Invasive Dural Penetration
According to Techub News, Elon Musk announced on June 30 that Neuralink has achieved a major technological milestone in brain-computer interface (BCI) development. The company's robotic system successfully implanted ultra-thin electrode threads directly through the intact dura mater into the brain without requiring an incision of this protective membrane. This innovation significantly reduces the trauma and risks associated with BCI surgery, paving the way for safer, more widespread applications.
Surgical Details: Electrode Threads Thinner Than Human Hair Avoid Blood Vessels
The technology utilizes polyimide electrode threads with a diameter smaller than that of a human hair. The precision robotic needle can penetrate the dura mater, which is over ten times the thread's thickness, while automatically avoiding blood vessels, thereby minimizing bleeding and nerve damage. Compared to traditional open-brain surgery, this method substantially reduces infection risk, shortens recovery time, and decreases direct trauma to brain tissue.
Application Prospects: Clinical Trials for Paralysis and Neurological Disorders
Neuralink is currently applying this technology in clinical trials for paralysis and neurological diseases, aiming to help patients who have lost motor function control external devices through brain signals. The realization of non-invasive penetration means that future BCI surgeries may no longer require large craniotomies, significantly lowering the barrier for patients to receive treatment. Musk stated that this progress marks an important step toward Neuralink's goal of a "full brain-computer interface."
