Key Takeaways
Teleoperated humanoid robots completed live gallbladder removals in a UC San Diego preclinical trial reported July 8 in Nature, a world first for the field.
The 5-foot, 60-pound robots cost and occupy a fraction of what 1,800-pound specialized surgical systems do, and could reach rural areas, disaster zones and battlefields.
The procedures ran far longer than on established systems because the robots needed repeated recalibration, and surgeon-to-robot latency remains a real hurdle.
For the first time, surgeons have used teleoperated humanoid robots to complete live operations. In a preclinical trial reported in the July 8 issue of Nature, a UC San Diego team removed the gallbladder of a large non-primate mammal with a humanoid robot while a human surgeon assisted, then ran a second procedure with two robots operating side by side at the table.
The robots, nicknamed Surgie, stand 5 feet tall and weigh 60 pounds. The specialized surgical systems in most operating rooms weigh about 1,800 pounds, need large teams to set up, and often require retrofitted rooms. The South China Morning Post reported the underlying machine is a general-purpose humanoid from China's Unitree Robotics, fitted with adapters so it can hold standard laparoscopic tools.
Shanglei Liu, the UC San Diego surgeon who teleoperated the robot during the study, said the humanoid is "a fraction of the cost and it takes a fraction of the space" of existing systems, easy to deploy from rural areas to the battlefield.
The mission case is access. Senior author Michael Yip pointed to a surgeon shortage that already means longer waits and wider healthcare disparities, and argued remotely operated humanoids could bring critical surgeries to patients who currently have no path to them, in the US and worldwide. The honest caveats are in the paper too. The robots needed recalibrating several times mid-procedure, so the operations ran much longer than they would on established systems, and the lag between a surgeon's hands and the robot's remains a constraint. The team's answer is history, the first robotic laparoscopic surgery took six hours and now takes 30 minutes.
The result extends a frontier-health lane we have been tracking all summer, from Neuralink threading an implant through the brain's intact dura to Aleph imaging a living human brain with ultrasound. The pattern here is hard to ignore. Hardware that gets cheaper and more general is what moves care toward the people who need it.
People Also Ask
Did a humanoid robot really perform surgery?
Yes, on live large non-primate mammals in a preclinical trial. Human surgeons teleoperated the robots the whole time, so the machines executed the surgeons' movements rather than making their own decisions.
Will humanoid robots replace surgeons?
No. The researchers describe them as tools to stretch a scarce supply of surgeons, first as operating room assistants that fetch tools and clean up, then as teleoperated hands in places that have no surgical team at all.
How is this different from existing surgical robots?
Today's specialized systems weigh about 1,800 pounds, sit fixed in retrofitted operating rooms and perform one kind of work. A 60-pound general-purpose humanoid is mobile, far cheaper, and can hold standard laparoscopic tools with simple adapters.
When could humanoid robots operate on humans?
There is no timeline yet. This was an early proof of concept, and recalibration, latency and regulatory review all stand between the trial and any human procedure.
