For the first time, robot operates a person without human interference

For the first time, a robot performed a surgery to a human patient unique of interference of human doctors.

In this case, the robot, which was formed with Surgery videosmade a Long phase of eliminating a gallbladder of a patient.

During the operation, the machine responded and learned Voice command of the team, as if it were a novice surgeon who learned from a mentor, reports the Eurekalert.

As the robot had surgery only in a human

During the tests the robot managed to pass successful and with experience of a human surgeon with extensive experience and qualified, even in unexpected but typical of real life emergencies;
The work was funded by the United States Federal Government, led by Johns Hopkins University;
“This advance transfers us from robots that can perform specific surgical tasks for robots that really They understand it Surgical procedures, “said medical robotist Axel Krieger;
“This is a critical distinction that gives us significant Clinically viable autonomous surgical systems that can act actually confusing and unpredictable to take care of the real patient ”;
The results were published Wednesday (9) at Science Robotics.

Something similar has already been done

In 2022 the robot Autonomous Robot of the smart fabric of Krieger (star) He did The first totally autonomous robotic surgery in a living animal. The patient was a porkthat went through a laparoscopic surgery.

But the robot, for the procedure, needed the fabric to be especially marked and the procedure was performed in a highly controlled environment and followed a rigid and predetermined surgical plan. Krieger said it was like teaching a robot at writing a well -combined route.

However, according to the expert, this new system “is like teaching a robot how to navigate any road, In any conditionIntelligent responding to everything you find. ,

The system

It Surgical Robot Transformer Hierarchy (SRT-H) goes further and performs surgeries, Adaptation to particular anatomical features of each patient real timemake decisions at once and automatically by correcting when things don’t go out as expected.

SR-H was built with the same architecture that feeds artificial intelligence (ia) Chatgptof Openai. It is interactivereply to spoken ordersas “to take the gallbladder”, and correctionslike “moving the left arm a little to the left”. The robot is able to do Learn from feedback of the human team.

“This work represents a big As for previous efforts, it addresses some of the fundamental barriers to the implementation of autonomous surgical surgical robots in the real world, “explained the main author Ji Woong” Brian “Kim, an old postdoctoral task at Johns Hopkins, currently at Stanford University.

“Our work shows that AI models can be Reliable For surgical autonomy: something that before, Looked far awayBut now it is proved viable“He added.

The system was used last year by Krieger’s team to train a robot that Three fundamental surgical tasks:

Manipulate a needle;
Raise body tissue;
Suture.

Each of these tasks took Few seconds. However, the removal of a gallbladder is much more complex: it is composed 17 long -term procedures.

The robot had to identify behaviors and arteries and clipping them, strategically clips and cutting the patient’s body parts with scissors.

SR-H has managed to make surgery only watching videos of operations by surgeons Johns Hopkins in pig corpses. Check the videos that allowed the machine to do the procedure with Total accuracy.

“Just as surgical residents often dominate different parts of an operation at different rhythms, this work illustrates the promise of developing autonomous robotic systems in a modular and progressive way,” says Johns Hopkins, Jopling, co -author of the project.

Another robot achievement was, for example, to take the steps perfectly And inside Few favorable anatomical conditions and in front of unexpected deviations, such as when researchers changed the initial position of the device and when they added dye Similar to human blood, which made the appearance of the gallbladder and the surrounding tissues change.

“For me, it really shows it Is possible Perform complex surgical procedures autonomously. This is a proof of concept that is possible and this imitation learning structure can automate such a complex procedure with a high degree of robustness, “said Krieger.
