About

Tsuyoshi Koyama is a pioneering researcher in the field of surgical robotics, with a focused expertise in orthopaedic interventions. His major contributions center on the development of robotic systems for minimally invasive spine surgery and complex fracture reduction procedures. Notably, Koyama led the creation of the "Needle Insertion Robot for Percutaneous Vertebroplasty," a system designed to enhance precision in spinal cement injection, which has garnered 18 citations for its foundational impact. He also advanced the "Robot Assisted Hip Fracture Reduction with a Navigation System," achieving 15 citations by integrating real-time imaging for safer alignment. A key innovation is his work on force/torque-controlled fracture reduction robots, where he introduced indirect traction—a method that reduces bone stress and prevents splits during femoral fracture repair. By gripping the patient's foot for traction, his system mimics standard surgical technique while adding robotic precision. Koyama’s research bridges engineering and clinical practice, offering safer, more reproducible outcomes. His work remains influential in the evolution of computer-assisted orthopaedic surgery, particularly for high-risk procedures where accuracy and force control are critical.
