Robotic surgery hits 'milestone' with autonomous gallbladder removal

MARYLAND, UNITED STATES, JUL 9 – The Surgical Robot Transformer-Hierarchy completed eight autonomous gallbladder removals with 100% task success, adapting in real-time to anatomical variations, Johns Hopkins researchers reported.

  • Earlier this week at Johns Hopkins University, a robot performed a gallbladder removal with 100% accuracy, as detailed in Science Robotics.
  • Building on this milestone, the two-tier AI system SRT-H was trained on 17 hours of surgical videos, learning from 16,000 human surgeon motions to enable autonomous performance.
  • In practice, SRT-H performed 17 surgical steps across eight pig gallbladders with real-time self-correction and voice-command responses, demonstrating high reliability.
  • Following this milestone, autonomous surgical robots move closer to routine use, achieving results comparable to expert surgeons but still requiring some human intervention, such as instrument changes.
  • Beyond lab tests, Johns Hopkins plans live animal trials, but regulatory approval and broader surgery types are necessary for clinical use.

As with the belief that coconut water is used to remove kidney stones or that lemon water is a ‘detox’ drink for the kidneys; some claim that there are home remedies for ‘cleaning’ the gallbladder. To this end, one of the most popular combinations is to take olive oil with herbs and natural fruit juice, and even beliefs point to the fact that doing so will presumably eliminate gallstones from the body. And yes, as with theories that mineral wate…
