Development of a Needle-Insertion Robot for MRI-Guided Stereotactic Surgery

Needle insertion in stereotactic brain surgery, such as electrode implantation for Parkinson’s disease, requires highly precise positioning control. MRI-guided robots are practical and promising in realizing safe, precise stereotactic brain surgery, but such robots must meet numerous constraints on component materials due to the strong magnetic field that MRI generates. We developed a needle-insertion robot for MRI-guided surgery taking into account such constraints.
