Robots Perform Remote Surgery on Live Animals

Humanoid robots, remotely controlled by human surgeons, have successfully removed gallbladders from live pigs in a groundbreaking preclinical trial. This advancement offers a more affordable and compact alternative to expensive, specialized surgical robots currently in use. The technology, demonstrated using a Unitree G1 humanoid robot, could enable surgeons to provide remote robotic-assisted care in smaller hospitals and rural areas lacking advanced medical resources.

The teleoperated robots, nicknamed "Surgie," required custom adapters and software for surgical tool manipulation and control. While the surgeries were successful, the experiment highlighted current limitations, including the need for frequent recalibration and longer operation times compared to established systems. Researchers are actively working to improve the robots' precision, reduce latency, and enhance their range of motion to overcome these challenges.

Looking ahead, the UC San Diego researchers envision these robots evolving into "autonomous surgical assistants" that can work alongside human surgeons, performing routine tasks. This development could significantly address global healthcare disparities by expanding access to critical surgical procedures, potentially transforming surgical care delivery worldwide.
