About
Ryutaro Hamano is a leading researcher in medical robotics, with a primary focus on enhancing the safety and precision of needle-based interventional procedures. His major contributions center on the development of robotic systems for central venous catheterization (CVC), a high-risk procedure where complications like pneumothorax and venous bleeding can arise from accidental punctures. Hamano’s work introduced a novel needle insertion manipulator designed to guide needles along optimal trajectories, quantitatively investigating how factors such as insertion angle and velocity affect puncture force and success rates. His foundational 2011 paper on this manipulator has garnered 42 citations, underscoring its influence in the field. Beyond CVC, Hamano has advanced robotic palpation-based needle insertion methods for breast tumor treatment, validated through both in vitro and in vivo studies. His research bridges engineering and clinical practice, aiming to reduce tissue displacement and improve targeting accuracy during biopsies and radiofrequency ablation. With a cumulative citation impact exceeding 80 across his key works, Hamano’s contributions are pivotal in making complex needle insertions safer, more reliable, and less dependent on physician intuition—a critical step toward autonomous or semi-autonomous surgical assistance.
