About

Kaiyuan Fan is a pioneer in the field of robotic-assisted orthopedic surgery, with a career dedicated to developing synergistic human-robot systems for knee procedures. His foundational work introduced the concept of "hands-on" robotic surgery, where a force-controlled robot is guided directly by the surgeon rather than operating autonomously. This paradigm shift is best exemplified in his landmark paper on the ACROBOT system (2002, 22 citations), which describes a mechatronic device that a surgeon can back-drive while feeling the real-time forces from a rotating cutter. This synergy allows for the precision of a robot with the tactile intuition of a human surgeon, dramatically improving the accuracy of prosthetic implant placement. His earlier experimental work (1997, 35 citations) laid the groundwork for these innovations, demonstrating the practical feasibility of robotic systems in total knee replacement. By prioritizing surgeon control and haptic feedback, Fan’s research has directly influenced the design of modern surgical robots, making complex procedures safer and more reproducible. His contributions remain a cornerstone for engineers and clinicians developing the next generation of interactive surgical tools.
