In a pioneering achievement, the Autonomous Multi-functional Oral Surgery Robot, developed by Academician Zhao Yimin's team at the Stomatological Hospital has successfully performed a complex orthognathic surgery. This marks the first time globally that a robot has independently executed bone cutting and positioning in such a procedure, showcasing China's leadership in autonomous oral surgery technology.

The robot completed the LeFort I osteotomy of the maxilla, precisely cutting and repositioning of jaw segments for patient, Xiao Ye, who suffered from significant jaw deformities affecting appearance and oral function. Correcting these issues through surgery was essential.

Key surgical steps, requiring millimeter-level precision, were independently handled by the robot. Under the guidance of Professors Shang Hongtao and others, the development team optimized the robot's instruments and control systems through extensive experimental studies, including animal model testing. These efforts enhanced the robot's safety, accuracy, and stability, meeting clinical demands and addressing traditional surgery challenges reliant on practitioner experience.

Before surgery, detailed 3D virtual planning was conducted using the patient's CT and dental scans to determine the optimal osteotomy planes. On the day of surgery, the robot followed the preoperative plan, utilizing intelligent algorithms and a high-precision robotic arm to complete the osteotomy and reposition the jaw segments, achieving improved appearance and bite function.

This success highlights the robot's capability to manage complex oral procedures, underscoring  the significant advantages of China's independently developed surgical robots. It offers intelligent solutions for various scenarios, enhancing military medical services and battlefield medical rescue capabilities.

This breakthrough not only demonstrates robotic technology's transformative potential in surgery but also supports medical equipment innovation and precision surgery development in China.
