An AI-powered robot successfully removed a gall bladder from a deceased pig in what researchers are calling a groundbreaking achievement in surgical automation with minimal human intervention.
The robotic system is equipped with a two-tier AI architecture trained on 17 hours of surgical video data, comprising 16,000 motions performed by human surgeons during operations. The first layer of AI analyzes live video feed from an endoscope and provides instructions in plain language, such as “clip the second duct”, while the second layer translates these instructions into precise three-dimensional tool movements.
The gall bladder surgery involved 17 distinct tasks, all of which the robot executed flawlessly in eight consecutive procedures.
“While current surgical robots have enhanced minimally invasive procedures, complication rates have not significantly decreased compared to traditional laparoscopic surgeries,” explains Axel Krieger from Johns Hopkins University. “This prompted us to explore the next generation of robotic systems that can benefit both patients and surgeons.”
“The study showcases the remarkable potential of AI and surgical robotics,” says Danail Stoyanov from University College London. “Advancements in computer vision for surgical video coupled with open robotic platforms have paved the way for demonstrating surgical automation.”
Despite the success of the robotic surgery, several challenges need to be addressed before the system can be implemented clinically, notes Stoyanov. The robot had to self-correct six times per procedure, indicating room for improvement in its precision. Additionally, some instances required human intervention, such as instrument changes.
Ferdinando Rodriguez y Baena from Imperial College London expresses optimism about the future of robotic surgery but emphasizes the importance of regulatory considerations for safe human applications.
The next phase of research involves testing the robot’s autonomy in live animal surgeries, where factors like breathing and bleeding introduce additional complexities.
