Steering needles and other minimally invasive instruments towards diseased tissue for diagnosis or treatment has the potential to minimize targeting errors and improve patient care. Currently no clinically applicable aids for accurate needle guidance exist. This research project aims to develop a system that uses shared control of needles with actuated tips for liver biopsy or tumor ablation.
MISIT focuses on the design of a flexible needle with the actuated tip and needle-tissue interaction experimental studies. The proposed needle steering device allows active manipulation of needle tip orientation which enables the needles to reach deep-seated locations within the body. Further, FBG sensors provide real-time pose of the needle essential for shared control.
