China’s MedBot Makes History With Autonomous AI Surgery Robot That Operated on a Live Pig
In a breakthrough that signals the future of surgical care, Shanghai-based MedBot has demonstrated an autonomous AI-driven surgical robot performing complex surgery on a live pig — without direct human control. The experiment, carried out in late December, marks a landmark moment in blending artificial intelligence and medical robotics and could redefine what’s possible in operating rooms around the world.

A New Chapter in Surgical Robotics
Traditionally, robotic surgery systems like the Da Vinci and MedBot’s own tele-operated platforms require surgeons to guide every movement. But MedBot’s latest experiment flipped that model. Using its Toumai robot, the system autonomously carried out intricate procedures on a 30-kg pig, executing crucial steps such as bile duct clamping and cutting. Impressively, the system completed about 88 % of the procedure independently on its first run, then adjusted in real time to finish the operation. (amp.scmp.com)
How the AI “Brain” Works
At the core of this achievement is a proprietary multimodal AI model — trained on billions of parameters and tens of thousands of surgical videos — that allows the robot to perceive, decide, and act much like a human surgeon. The model integrates real-time visual data from the surgical field and feedback from instruments to make decisions mid-operation, a leap from remote-controlled robotic surgery to true autonomy.

MedBot frames this milestone as the first of its kind in the world, moving beyond tele-operations to real autonomous robotic surgery. While expert clinical supervision remained part of the process, the robot’s performance shows how advanced AI could support — and perhaps someday augment or extend — human surgical expertise.

What This Means for Healthcare
Although this technology is still in animal trials and far from clinical use on humans, its implications are compelling:
- Reduced surgeon workload: Autonomous systems could take on repetitive or highly precise steps, letting surgeons focus on planning and oversight. (amp.scmp.com)
- Greater access to surgical care: If perfected and approved, such robots might help deliver high-quality surgery in regions with limited specialist availability. (Firstpost)
- New regulatory and ethical terrain: Widespread clinical use will require navigating safety standards, liability frameworks, and public trust in machine-led interventions. (Wikipedia)
