Robotically steering flexible needles are capable of reaching the intended target in tissue with sub-millimeter level accuracy.
Scientists from The University of Twente (The Netherlands) have developed a robot-assisted system for steering flexible needles with an asymmetric tip. These robotically steering flexible needles can reach their intended target in tissue with sub-millimeter level accuracy. As well, these robotically steering flexible needles can more readily avoid obstacles or sensitive tissues and are capable of reorientation in real time.
