全国首例！西藏日喀则成功实施机器人辅助生物膝关节置换术

Core Viewpoint - The article highlights a significant advancement in orthopedic surgery through the successful implementation of a robot-assisted biological total knee replacement surgery in Tibet, marking a breakthrough in high-altitude medical technology [1][5]. Group 1: Surgical Innovation - The surgery was performed by a team led by Professor Zhang Yuan from the Army Medical University, utilizing the domestic "Kuanlu" orthopedic surgical robot, which is tailored for the unique bone quality and development characteristics of Tibetan patients [1][2]. - This operation is noted as the first robot-assisted biological knee joint replacement surgery in the country, showcasing the integration of advanced technology in challenging environments [1][5]. Group 2: Challenges and Solutions - The patient had suffered from severe knee pain and deformity, with traditional surgery facing challenges such as bone loss, high-altitude reactions, and strict standards for biological knee implants [1][2]. - The surgical team developed an innovative plan that included 3D reconstruction of the knee joint structure and real-time monitoring of joint pressure during the operation, ensuring precision and optimal outcomes [2][5]. Group 3: Local Capacity Building - Following multiple digital surgical tours and over sixty surgeries, local doctors have gained the ability to independently operate the "Kuanlu" robotic system, allowing Tibetan patients to access top-tier medical technology without traveling long distances [4][5]. - This initiative represents a model for balancing medical resources in remote areas, combining expert technology transfer, local team training, and support from domestic equipment [5]. Group 4: Technological Advancements - The "Kuanlu" surgical robot has completed over 4,000 joint replacements since its introduction, demonstrating its reliability in extreme conditions, including temperatures ranging from -20°C to 40°C and oxygen levels significantly lower than at sea level [5]. - The integration of a force-sensing pad developed with funding from a key project in Chongqing enhances the robot's capabilities, allowing for precise bone cutting and real-time soft tissue balance [5].
