Just like a real surgeon: Robot removes gallbladder with 100pc accuracy
NEW YORK, July 10 — A robot has performed realistic surgery on its own with 100 per cent accuracy, PA Media/dpa reported. Researchers at Johns Hopkins University in the United States (US) said in a 'major leap' towards using more robots in operating theatres, a machine trained on the videos of surgeries was able to precisely work on removing a gallbladder. The robot operated with the expertise of a skilled human surgeon, according to the researchers, even during unexpected scenarios typical in real-life medical emergencies. The robot was watched as it performed a lengthy phase of a gallbladder removal on a life-like patient. It was able to respond to and learn from voice commands from the team, just like a novice surgeon working with a mentor. Overall, there were 17 tasks in the surgery. The robot had to identify certain ducts and arteries and grab them precisely, strategically place clips, and sever parts with scissors. It was also able to adapt even when dye was introduced, which changed the appearance of the organs and tissue. Associate professor in mechanical engineering Axel Krieger said the advancement signifies a move from robots that can execute specific surgical tasks to robots that truly understand surgical procedures. 'This is a critical distinction that brings us significantly closer to clinically viable autonomous surgical systems that can work in the messy, unpredictable reality of actual patient care.' The work received US government funding and was published in the journal Science Robotics. Back in 2022, a robot performed the first autonomous robotic surgery on a pig. However, it required specially marked tissue, operated in a highly controlled environment, and followed a rigid, pre-determined surgical plan. Krieger said that phase was like teaching a robot to drive along a carefully mapped route. But the new system was 'like teaching a robot to navigate any road, in any condition, responding intelligently to whatever it encounters.' 'To me, it really shows that it's possible to perform complex surgical procedures autonomously,' he said. The new system, which uses the same machine learning architecture that powers ChatGPT, also adapts to a patient's anatomical features in real-time and works to correct itself. It can respond to spoken commands such as 'grab the gallbladder head' or 'move the left arm a bit to the left,' and then learns from that feedback. Ji Woong Kim, a former postdoctoral researcher at Johns Hopkins who is now at Stanford University, said this work represents a major leap from prior efforts because it tackles some of the fundamental barriers to deploying autonomous surgical robots in the real world. 'Our work shows that AI models can be made reliable enough for surgical autonomy – something that once felt far-off but is now demonstrably viable,' said Kim. Although the robot took longer to perform the work than a human surgeon, the results were comparable to an expert surgeon, researchers said. Next, the team will train and test the system on more types of surgeries. — Bernama-PA Media/dpa

Study describes robot operating on gall bladder autonomously, milestone in use of AI in clinical setting
New Delhi, Jul 10 (PTI) Researchers have documented a fully autonomous surgery performed by a robot on gall bladders made of human tissue with 100 per cent accuracy, which they said marked a milestone in deploying these systems in a clinical setting. In a paper published in the journal 'Science Robotics', the team, led by researchers at Johns Hopkins University in the US, said the robot 'SRT-H' was trained on the videos of surgeons operating on dead pigs. Powered by artificial intelligence (AI) algorithms that systems such as ChatGPT function on, the 'Surgical Robot Transformer-Hierarchy', or SRT-H, also responded to and learned from voice commands from the team while performing the operation -- like a novice surgeon working with a mentor, they added. "This advancement moves us from robots that can execute specific surgical tasks to robots that truly understand surgical procedures," author and medical roboticist Axel Krieger from Johns Hopkins University said. "This is a critical distinction that brings us significantly closer to clinically viable autonomous surgical systems that can work in the messy, unpredictable reality of actual patient care," Krieger said. The team had previously documented a laparoscopic surgery performed by a robot on a pig -- the first autonomous one on a live animal, they said. However, the robot had required a tissue that was specially marked for surgical intervention, worked in a highly controlled environment and followed a rigid, predetermined surgical plan. The SRT-H robot truly performs surgery, adapting to individual anatomical features in real-time, making decisions on the fly, and self-correcting when things don't go as expected, the researchers said. They wrote, "We propose a hierarchical framework for performing dexterous, long-horizon surgical steps. "Our method achieves a 100 per cent success rate across eight different ex vivo gallbladders, operating fully autonomously without human intervention." The work marks a "milestone towards clinical deployment of autonomous surgical systems," they wrote. They added that while the robot took longer to operate as compared to a human surgeon, results were comparable to an expert surgeon. Lead author Ji Woong Kim, a former postdoctoral researcher at Johns Hopkins University, said, "This work represents a major leap from prior efforts because it tackles some of the fundamental barriers to deploying autonomous surgical robots in the real world." "Our work shows that AI models can be made reliable enough for surgical autonomy -- something that once felt far-off but is now demonstrably viable," Kim said.

Robot performs realistic gallbladder surgery 'with 100% accuracy'

Nuha Yassin, consultant colorectal surgeon and council member and lead for the future of surgery, robotics, and digital surgery at the Royal College of Surgeons of England (RCS England), said: "It's always exciting to see new developments in surgical innovation, especially in areas like robotics and digital surgery. "That said, the real test will be how safely and effectively the findings of this study can be translated into human trials. We need to make sure that progress doesn't come at the expense of patient safety."

Experimental surgical robot performs gallbladder procedure autonomously
Bengaluru: An experimental AI-guided robot can autonomously perform a delicate, complicated phase of a common gallbladder operation , marking a major step toward automated medical procedures, researchers said on Wednesday. Existing surgical robots are remotely controlled by surgeons. The new system uses artificial intelligence to make independent decisions and adapts to unexpected complications during operations, said Axel Krieger of Johns Hopkins University in Baltimore, who led the research. He likened it to an autonomous vehicle that can "navigate any road, in any condition, responding intelligently to whatever it encounters." "This advancement moves us from robots that can execute specific surgical tasks to ones that truly understand surgical procedures," he said. The SRT-H robot was trained via an AI framework known as language-guided imitation learning, using videos of surgeons performing gallbladder removal surgeries on pig cadavers, the researchers reported in Science Robotics. The robot was tested on eight varying sets of pig gallbladders and livers that had been removed from the animals. Separating the gallbladder from the liver takes several minutes and involves "diverse tool use, including grabbing, clipping, and cutting - skills common in real surgical procedures," along with decision-making and adaptation, the researchers said. The pig organs and blood vessels in the tests varied widely in appearance and anatomy, "mirroring the diversity encountered in human surgeries," they said. While the robot achieved 100% accuracy in the surgeries, it took longer to perform the work than a human surgeon. Commercially available surgical robots include Intuitive Surgical's da Vinci Surgical System, which has been used in over 12 million procedures globally since receiving FDA approval in 2000. Unlike SRT-H, the da Vinci system relies entirely on human surgeons to control its movements remotely. The global surgical robotics market is approaching $10 billion annually with about 2.7 million robotic procedures performed in 2024, Baird analyst David Rescott estimated. Eventually, autonomous surgical robots could help address surgeon shortages, minimize human error, and provide consistent, high-quality care in underserved regions, the researchers said.
