Doctors in Hong Kong performed the world's first robotic living-donor liver transplanttransplant/ˈtrænsplænt/L2移植（手术）an operation in which a doctor moves an organ from one person's body to another person's body. A team from the University of Hong Kong shared the results of a clinical trial. Since June 2025, surgeons at Queen Mary Hospital completed 48 procedures. None of the patients had long-term or post-operative complications.
The robotic system helps surgeons overcomeovercome/ˌoʊvərˈkʌm/L2克服，战胜to succeed in dealing with a problem or difficulty a common difficulty of microsurgery. Dr Velda Chow said, "The biggest difficulty of microsurgery is hand tremorstremors/ˈtrɛmərz/L2颤抖，震颤small, uncontrolled shaking movements, especially in your hands." The robot filters out these tremors and provides a stable view. The surgeon sits in a chair and controls the robotic arms with joysticks. Wearing 3D goggles, the surgeon sees a magnified view of the surgical site.
In April, the team used the system in a living-donor liver transplant for the first time globally. Professor Albert Chan said the challenge was reconnecting a tiny artery. He explained, "If the reconnected hepatic artery becomes blocked, the new liver will fail to function." The robot's precisionprecision/prɪˈsɪʒən/L2精确，精准the quality of being very exact and accurate reduces this risk. The team hopes to use robotic microsurgery routinelyroutinely/ruːˈtiːnli/L2常规地，例行地as part of a regular process or habit; done often and in the usual way in public hospitals.
