The Orthopedic Surgery and Rehabilitation Medical Robotics team, led by Professor Sun Tao from the School of Mechanical Engineering at Tianjin University, consists of 1 national/provincial-level high-level talent, 2 professors, 2 assistant researchers, and 8 doctoral students. The team focuses on robot structural design theory and key technologies in medical robotics. Several technologies have been validated through in vivo animal experiments and clinical trials, resulting in 27 national invention patents. They have received awards such as the China Good Design Gold Award, the First Prize for China Industry-University-Research Cooperation Innovation Achievements, the First Prize for Tianjin Technical Invention, and the China Patent Excellence Award, and have been selected as one of China's top ten technological advances in intelligent manufacturing.

　　The team concentrates on intraoperative diagnosis, personalized rehabilitation techniques, intelligent monitoring, and robotic surgery in the field of orthopedic surgery. They have successfully developed mature orthopedic surgical robot systems, orthopedic surgery navigation systems, and orthopedic rehabilitation robot systems. These platform products effectively address industry challenges such as the high trauma and low visualization of traditional orthopedic surgery, as well as the difficulty in popularizing complex surgical techniques. By introducing these products, surgical risks can be significantly reduced, the treatment period for fracture surgeries can be shortened, complications can be deferred or reduced, and precise quantification of fracture reduction trajectories and rehabilitation exercise plans can be implemented, greatly improving the accuracy of reduction and saving substantial medical costs for patients with traumatic fractures.

　　The highly accurate, widely applicable, and cost-effective orthopedic surgery and rehabilitation medical robotics system developed by the team is suitable for various fields such as grinding, welding, assembly, surgery, and rehabilitation. The medical device product registration certificate is currently in the final review (pending approval) stage and has completed multiple clinical trials in collaboration with the First Hospital of Hebei Medical University, Tianjin Hospital, and others. Additionally, the team closely collaborates with universities, research institutes, and businesses, and the technology patent conversion has exceeded one million.

　　The team relies on the Key Laboratory of Mechanism Theory and Equipment Design of the Ministry of Education at Tianjin University and the Institute. Addressing the industry pain points of large trauma, low visualization, and limited adoption of complex orthopedic surgeries, they utilize key core technologies such as intelligent robotics, multimodal image fusion, intelligent diagnosis and treatment, and quantitative rehabilitation. They have developed a highly precise, widely applicable, and cost-effective orthopedic surgery and rehabilitation medical robot system. The team has received numerous awards and recognitions, including Tianjin Science and Technology Invention First Prize, China Industry-University-Research Collaboration Innovation Achievement First Prize, China's Top Ten Technological Progresses in Intelligent Manufacturing, China Good Design Gold Award, Youth Science and Technology Achievement Award from the China Mechanical Engineering Society, and Excellent Patents Award in China. In the field of orthopedic medical robots, they have published over 20 academic papers and applied for/obtained 27 national invention patents, 10 PCT patents, 5 US patents, and 7 software copyrights (with a patent conversion of 1 million RMB for surgical reduction software).

　　The Orthopedic Surgery and Rehabilitation Robot

　　Traditional fracture reduction surgeries lack quantified implementation by robots, leading to a significant disconnect between surgery and rehabilitation information and procedures, hindering the full-cycle management of bone healing. The team provides a digital, wearable fracture reduction and rehabilitation integrated robot solution for fracture treatment. It reliably immobilizes the fractured bone, precisely implements fracture reduction trajectories, and rehabilitation exercise plans, significantly improving reduction accuracy and surgical success rates.。

　　Fracture Reduction Trajectory Planning Software

　　Traditional surgeries often struggle with accurately measuring the position of fractured bones and instruments, lacking trajectory planning for reduction. This deficiency can lead to issues like soft tissue damage, secondary fractures, and low reduction accuracy. The software enables precise measurement of bone and instrument positions, automatically generating optimal reduction trajectories. It guides external fixation instruments, achieving reduction accuracy within 1.1mm and 1.2°, effectively improving fracture reduction outcomes.
