Cloud Communication -- The 26th UBE Technology Online Live Broadcast of The Fifth Affiliated Hospital of Sun Yat-sen University Concludes Successfully
On November 26, 2025, the 26th UBE Technology Online Live Broadcast, led by the Spinal Surgery Team of The Fifth Affiliated Hospital of Sun Yat-sen University (Zhongshan No.5 Hospital), concluded successfully. This cloud grand event integrating technical demonstration and academic exchange attracted 24,000 orthopedic colleagues from home and abroad to watch online, thanks to the delicate operation of high-difficulty surgeries, the innovative application of AI navigation, and real-time interactive discussions, becoming a vivid practice of cross-regional academic exchange in the field of spinal minimally invasive surgery.
This live broadcast was performed by Professor Lü Hai (Director of Spinal Surgery, Zhongshan No.5 Hospital, postdoctoral fellow who studied in the United States), Professor Zhang Kuibo, and Professor Chen Tao as the chief surgeons, focusing on the minimally invasive treatment of complex lumbar spinal stenosis using UBE (Unilateral Biportal Endoscopy) technology. Throughout the surgery, the AI navigation system was innovatively integrated: preoperatively, 3D reconstruction was completed using the patient’s spinal CT and MRI data to intelligently plan the optimal surgical approach and operation trajectory, accurately avoiding areas with dense nerves and blood vessels; intraoperatively, the navigation reference frame was fixed on the patient’s posterior superior iliac spine, and submillimeter-level positioning and guidance were achieved through real-time image registration and optical tracking technology. Supported by both a 30x high-definition endoscopic field of view and AI navigation, the team completed endoscopic observation and instrument operation through two small channels of only 0.8-1cm respectively. The navigation probe confirmed anatomical structures in real time to avoid intraoperative visual disorientation, and under a clear surgical field continuously irrigated with normal saline, calcified compressive lesions were accurately ground and nerve roots were decompressed. The entire process resulted in less than 20ml of bleeding, which not only maintained the advantages of UBE technology—"small incision, large field of view, and high precision"—but also further improved the safety and accuracy of treating complex lesions through AI navigation.
During the live broadcast, the chief surgeon team simultaneously explained the key points of the collaboration between AI navigation and UBE technology, including preoperative planning logic, intraoperative trajectory calibration, and intelligent auxiliary strategies for nerve protection. Barrage interactions heated up continuously, and spinal surgeons from home and abroad conducted in-depth discussions on topics such as "the application value of AI navigation in complex UBE cases", "the integration path between minimally invasive technology and intelligent medical care", and "postoperative rapid rehabilitation plans", forming a positive atmosphere of academic collision. As the core technology combination of this surgery, UBE technology effectively solves the problem of instrument interference in traditional single-port endoscopic surgery through its biportal design, while AI navigation overcomes the positioning difficulties in complex spinal stenosis cases through preoperative intelligent planning and intraoperative real-time guidance. The collaboration of the two achieves dual guarantees of minimal invasiveness and definite curative effect. According to data from the Spinal Surgery Department of Zhongshan No.5 Hospital, patients with spinal diseases treated with this technology combination can get out of bed and walk 1 day after surgery, and the hospital stay is shortened to 3-5 days. The patient who underwent surgery during this live broadcast successfully got out of bed for short-distance activities on the second day after the operation, with stable vital signs and expected rehabilitation progress, fully verifying the clinical value of the combination of AI navigation and UBE technology.
As a national postdoctoral research station and a promotion base for minimally invasive spinal surgery technology, the Spinal Surgery Department of Zhongshan No.5 Hospital has long focused on the innovative integration of spinal minimally invasive technology and intelligent medical care. Professor Lü Hai stated: "Online live broadcasts break regional restrictions, allowing experts from Hong Kong (China), Bangladesh, Switzerland, and other regions to observe the operational details of high-difficulty surgeries and the core application of AI navigation 'zero distance'. This is not only a technical demonstration but also a sharing of experience. In the future, we will continue to build such academic exchange platforms to promote the standardized development of spinal minimally invasive technology and intelligent medical care, and bring advanced medical technology to more patients."
I can help you polish the English translation to enhance its academic formality and fluency, and also adjust the sentence structure to better fit international medical academic expression. Need me to do that?
