Surgeons Conduct Live Surgery with Teleoperated Robots

Researchers have successfully conducted two surgeries using teleoperated humanoid robots in a preclinical trial, marking a first in medical robotics, according to a study published July 8 in *Nature*. The trial, led by a collaboration between University of California San Diego engineers and surgeons, demonstrated the feasibility of remote surgical procedures using advanced robotic systems. Two humanoid robots, controlled in real time by surgeons via virtual reality and haptic feedback, performed a vascular anastomosis and a laparoscopic cholecystectomy on animal models. The surgeries were conducted across a 1,600-kilometer distance, with one robot in California and the other in Arizona, under the guidance of operating surgeons in San Diego.

The study highlights the potential of humanoid robotics to expand access to specialized surgical care in remote or underserved areas. The robots, equipped with dexterous hands and precision tools, executed complex tasks requiring fine motor control and real-time adaptability. Surgeons reported minimal latency in control and high procedural accuracy, with outcomes comparable to traditional methods. The team emphasized the importance of integrating intuitive user interfaces and robust communication systems to ensure reliability in clinical settings. While the trial focused on preclinical models, the researchers noted that further testing and regulatory approvals are necessary before human applications can be pursued.

This breakthrough underscores the growing intersection of robotics and healthcare, offering a glimpse into the future of remote surgery. The collaboration between engineering and medical experts demonstrates how interdisciplinary innovation can address longstanding challenges in surgical accessibility. As the technology advances, the study authors anticipate iterative improvements in robotic autonomy, safety protocols, and scalability, potentially paving the way for broader adoption in clinical practice within the coming decade.
