AI for Good: AI robot performs gallbladder removal with perfect accuracy

A surgical robot trained on video demonstrations has autonomously performed gallbladder removals with 100% accuracy.
Johns Hopkins University researchers developed the Surgical Robot Transformer-Hierarchy (SRT-H), which completed eight separate procedures on realistic models without human intervention. The robot learned through imitation learning, analyzing 17 hours of surgical demonstrations and over 16,000 recorded movements, then executed all 17 complex steps required for gallbladder removal.
“This advancement moves us from robots that can execute specific surgical tasks to robots that truly understand surgical procedures,” said Axel Krieger, the Johns Hopkins medical roboticist who led the research.
Unlike previous surgical robots that required pre-marked tissue and predetermined plans, SRT-H adapts to unexpected conditions in real time. During testing, researchers changed the robot’s starting position and added blood-like dyes that altered tissue appearance, but the system adjusted smoothly and maintained perfect accuracy.
Key capabilities demonstrated:
Responds to voice commands like “grab the gallbladder head” and learns from corrections. Makes autonomous decisions about which surgical step to perform nextSelf-corrects mistakes during procedures, averaging 6.4 adjustments per operationUses transformer neural networks—the same AI architecture that powers ChatGPT—to process visual and language information
The robot took about five minutes per procedure, longer than human surgeons, but demonstrated smoother, more precise movements.
Why it matters: Autonomous surgical systems could transform healthcare by providing expert-level operations in areas with surgeon shortages, reducing complications from human fatigue and delivering consistent precision. With over 5 billion people lacking access to safe, affordable surgery, AI-guided robots could democratize access to life-saving procedures worldwide.
