摘要: Needle insertion is a critical aspect of many medical treatments, diagnostic methods, and scientific studies, considered to be one the simplest most minimally invasive procedures. Robot-assisted needle steering has potential improve effectiveness existing procedures enable new ones by allowing increased accuracy through more dexterous control needle-tip path acquisition targets not accessible straight-line trajectories. In this article, we describe robot-assisted needle-steering system that uses three integrated controllers: motion planner concerned with guiding around obstacles target in desired plane, planar controller maintains torsion compensator controls orientation about axis shaft.
