Sophisticated, This Robot Can Perform Complex Operations Without Human Assistance
1/28/2022
The development of technology in the medical world is very advanced. The use of robots in the operating room is also not new. Doctors have used certain robotics to assist during the surgical process.
But what if one day robotic surgeons could operate on people without needing a doctor's help? That doesn't seem impossible. The reason is, currently researchers at Johns Hopkins University are developing the robot.
Reported by Gizmodo , Axel Krieger and his colleagues are developing the Smart Tissue Autonomous Robot or STAR. A robot that can perform surgical procedures without human intervention.
“STAR is the first robotic system to plan, adapt, and execute surgical plans in soft tissue without human intervention,” Krieger, assistant professor of mechanical engineering at Johns Hopkins told Gizmodo in an email.
In a new test published in Science Robotics on Wednesday, they presented data showing that STAR can independently perform complex soft tissue surgery in pigs laparoscopically, meaning it is performed with only small incisions.
This operation is known as a small bowel anastomosis in which the ends of the intestine need to be reattached (for example, when part of the intestine is removed to treat a tumor). This operation requires precision and accuracy. Even a small mistake can cause a leak considering this is a soft tissue.
The results shown by STAR are also quite good. Compared to data obtained from human operations, the team reported that STAR sutures and sutures were found to be more accurate and consistent. No leaks were detected in the operated pigs.
Even so, Krieger said it would take some innovation to get STAR to do this kind of complex task automatically. For example, standard Peruvian surgical instruments were modified.
The robot is also equipped with a combination of a near infrared camera and a structured light to reconstruct a three-dimensional image of the surgical site. It also requires programming to create a customized surgical plan.
Although this looks so promising, it doesn't look like it will be used in medicine in the near future. The robot looks like it will still be playing the role of a doctor's assistant instead of taking the job entirely. (*)
