About

Yu Matsumoto is a pioneering researcher in surgical robotics, with a focus on developing precise, minimally invasive systems for orthopedics and otolaryngology. His work addresses critical challenges in procedures where anatomical constraints demand high accuracy and safety. Matsumoto's early contribution, "Control of fracture reduction robot using force/torque measurement" (2008, 3 citations), introduced a robotic system for femoral fracture reduction that employs indirect traction—a method that reduces the risk of bone splits by minimizing stress. This work laid groundwork for safer orthopedic interventions. More recently, his 2025 paper "A Robot for Transcanal Endoscopic Ear Surgery with Gimbal-based Rotational Linkage and Linear Guide Rail Mechanisms" (2 citations) tackles the extreme spatial limitations of ear surgery, where instruments must operate within a canal less than 1 cm in diameter. By designing a gimbal-based rotational linkage and linear guide rail, Matsumoto enables simultaneous endoscope and tool insertion, enhancing dexterity and precision in transcanal endoscopic ear surgery (TEES). His research exemplifies the fusion of mechanical innovation with clinical need, advancing robotic assistance in challenging surgical environments and inspiring future developments in medical robotics.
