摘要：
A robotic device for performing intracranial procedures, comprising a baseplate for mounting on the subjects skull and a rotatable base element rotating on the baseplate. The rotatable base element has a central opening through which a cannulated needle can protrude such that it can rotate around an axis perpendicular to the baseplate. This cannulated needle is robotically controlled to provide motion into and out of the subjects skull. A flexible needle is disposed coaxially within the cannulated needle, and it is controlled to move into and out of a non-axial aperture in the distal part of the cannulated needle. Coordinated control of the insertion motion of the cannulated and flexible needles, and rotation of the combined cannulated/flexible needle assembly enables access to be obtained to a volume of a region of the brain having lateral dimensions substantially larger than the width of the cannulated needle.
