Without human intervention – in the United States, the surgeon robot performed a complex operation on an animal.

In the United States, the autonomous surgeon robot STAR, created at Johns Hopkins University, performed the first laparoscopic surgery on the intestines of a pig. And he did it better than people could.

For robots, performing operations on soft tissues is especially difficult due to their unpredictability, which requires the ability to quickly adapt to unexpected obstacles, so the success of STAR, according to scientists, is an important step towards fully automated operations on humans in the future.

It is noted that surgeon robot STAR has a control system that can adjust the surgical plan in real time, as a surgeon would.

Our results show that we can automate one of the most complex and delicate tasks in surgery, the reconnection of the two ends of the intestine. STAR performed the operation on four animals and performed better than humans, the researchers emphasize.

The surgeon robot successfully performed a laparoscopic (performed through small incisions in the body) surgery to anastomose the intestines of a pig.

Scientists emphasize that such operations are a difficult task for soft tissue surgery, since they require:

– complex visualization;
– tissue tracking;
– application of methods of surgical planning;
– accurate execution using adaptive control strategies, often in unstructured and deformed environments.

In laparoscopic conditions, such operations are even more difficult due to the need for high maneuverability and repeatability while limiting movement and vision, the researchers emphasize.

The robot that performed the operation has an imaging system, built-in surgical instruments, including specialized suturing instruments, as well as a patient monitoring system for correcting actions in real time.
