About

Lihai Zhang is a biomedical robotics researcher whose work sits at the intersection of surgical robotics, orthopedic engineering, and rehabilitation technology. His research has made meaningful contributions to the development of robotic systems for fracture reduction surgery, with a particular focus on diaphyseal and pelvic fractures — some of the most technically demanding procedures in trauma orthopedics. Zhang's most influential work introduced a master–slave teleoperation robot system for diaphyseal fracture reduction (31 citations), advancing the precision and safety of minimally invasive bone repair. Complementing this, his systematic accuracy analysis of closed fracture reduction robots (21 citations) established rigorous benchmarks essential for both patient safety and surgical reliability. More recently, he has tackled the complexities of pelvic fracture surgery through the development of series-parallel hybrid robotic systems integrating advanced navigation and human-robot collaborative control, alongside novel 2D X-ray to 3D CT image registration algorithms that improve intraoperative guidance. Beyond orthopedic surgery, Zhang has extended his expertise to rehabilitation robotics, exploring robot-assisted weight-bearing exercise for stroke patients with limited mobility. Collectively, his body of work — spanning over 70 citations — reflects a sustained commitment to making complex surgical and rehabilitative procedures safer, more accurate, and more accessible through intelligent robotic solutions.
