The robot operated on a lifelike patient. During the procedure it responded to and learned from voice commands from the team, likened to a novice surgeon working with a mentor. The robot performed with the expertise of a skilled human surgeon across the trials, even during unexpected scenarios typical in real-life medical emergencies, according to the researchers. The federally funded work marks an advancement in surgical robotics, where robots can perform with both mechanical precision and human-like adaptability and understanding. The surgery was carried out at the USA's Johns Hopkins University in Baltimore, Maryland. Gallbladder removal is a complex string of 17 tasks. The robot, called SRT-H, had to identify certain ducts and arteries and grab them precisely, strategically place clips, and sever parts with scissors. It learned how to do the gall bladder work by watching videos of Johns Hopkins surgeons doing it on pig cadavers. The team reinforced the visual training with captions describing the tasks. After watching the videos, the robot performed the surgery with 100% accuracy. Although the robot took longer to perform the work than a human surgeon, the results were comparable to an expert surgeon. A spokesperson said: "The robot performed unflappably across trials and with the expertise of a skilled human surgeon, even during unexpected scenarios typical in real life medical emergencies.” Picture supplied by JLPPA
