A Chinese research team has successfully utilized geostationary satellite communication (632 ms latency) to remotely control robotic surgical systems in Beijing from Lhasa, performing precision liver resection surgeries on two liver cancer patients. Intraoperative robotic arm tracking error remained below 0.5 mm, with both patients discharged within 24 hours postoperatively and no severe complications reported. This study marks the first validation of safety in remote surgery under high-latency satellite conditions, offering a groundbreaking solution for underserved regions, disaster zones, and space medicine.
