Many engineers designed as self-driving cars, Wednesday’s research is part of a move to autonomous surgical robots, removing the hands of the surgeon certain tasks that can execute a machine in itself.

No, doctors will not let the night â ?? “They are designed to hold, plus they have to handle the rest of the operation supervision. The device is also not ready for the operation room.

However, in small-scale tests using pigs, the robot arm performed at least as well, and in some cases a little better than some competitive surgeons stitched together intestinal tissue, researchers reported in the journal Science Translational Medicine.

“the goal was not it feel replacing surgeons, “Dr. Peter CW Kim children National Health System said in Washington, a pediatric surgeon who led the project.” If you’re an intelligent application that works with a surgeon, this can improve the outcome? That’s what we did. “

If you heard about machines like the popular Da Vinci system, what you think robots already working. Not really. Today many hospitals offer robotic-assisted surgery where surgeons use the machines as tools they with the hand control, typically to operate through small openings in the body. However, robotic-assisted surgery controversial, as some studies have shown that may bring higher costs without better outcomes.

so why the pressure for the next generation of autonomous robots? Proponents believe that there are cases where precision machine se can surpass a human hand.

Wednesday project is “the first baby step toward true autonomy,” says Dr. Umamaheswar Duvvuri from the University of Pittsburgh Medical Center, a head and neck surgeon and robot specialist who was not involved with a new job.

But do not expect to see doctors ever leaving all operations in numbers “a robot’s he warned .

Because it’s designed to do a specific task ?? “Put up fabric â ??” the machine is a very such as the automation trend in other sectors. robot arms do the welding and painting in the most American car assembly lines, for example. They can find inventory in warehouses. From the viewpoint of the driver many cars are now able to warn drivers when they get too close to the car in front of, or to prevent the control and the brakes applied to an accident.

â the new star system ?? “It stands for â Smart Tissue Autonomous Robot ??” works almost as a programmable machine.

Kim’s team at Sheikh Zayed Institute for Children for Children Surgical Innovation has a standard robotic arm and equipped with suture devices plus smart imaging technology to make the trace move tissue in 3-D and with an equivalent of the night vision. She added sensors to help guide every stitch and tell how tight draw.

The surgeon places fluorescent markers on. tissue that needed stitching, and the robot takes aim as doctors watch

Now the test: Can the STAR tire tube pieces of the intestinal tissue of pigs, sort of like two sides of a garden hose Each soft? tissue, surgery is difficult for machines because these tissues in place to move so easily. And stabbing in these compounds must precisely positioned even for experts to occur leaks or blockages, a challenge.

The use of pieces of pork intestine bodies outside the animals’ as well as five live but anesthetized pigs, the researchers have tested the STAR robot to open surgery, minimally invasive surgery and robotic-assisted surgery.

â some action ?? “The consistency of sutures and their ability to prevent leaks â ??” “We beat the surgeons,” says Children engineer Ryan Decker.

The star approach was not perfect. The Star has less than stabbing reposition the surgeons performing minimally invasive and robot-assisted suture. But much longer in the lives of animals, the robot and have some bonding errors while the surgeon sew handmade.

Kim, whose team has filed patents on the system, said it may accelerate the robot. He hopes to begin human trials in two or three years.
