US EditionAI Surgical Robot Achieves Flawless Gallbladder Removal on Pig Cadavers
UNITED STATES, JUL 10 – The Surgical Robot Transformer-Hierarchy completed 17 complex gallbladder removal tasks with 100% accuracy on pig cadavers, marking a major step toward autonomous surgeries, researchers said.
- On July 9, 2025, Johns Hopkins researchers announced that a robot autonomously performed a gallbladder removal on a pig cadaver with 100% accuracy in a laboratory setting.
- This milestone followed prior work in 2022 when Axel Krieger's team created AI systems that taught robots foundational surgical skills by watching videos and performing small animal surgeries.
- The robot completed the 17-step procedure eight times, self-correcting multiple times and responding to voice commands, demonstrating adaptability even during unexpected situations.
- Ji Woong Kim stated that their research demonstrates AI technology has reached a level of dependability suitable for autonomous surgery, while Krieger highlighted that the system responds dynamically to anatomical variations in real-time, similar to how a human surgeon operates, marking a significant advancement toward practical clinical use of autonomous surgical robots.
- Researchers stressed the need for further testing, expanded surgical capabilities, and regulatory approval before clinical use, as challenges remain to safely translate this technology to human patients.
