Scientists have developed a robotic system that allows neurosurgeons to perform endovascular interventions remotely. The new technology is designed to save the lives of patients in a critical situation, for example, after a stroke, who need to be operated on immediately to preserve brain function. In the future, the availability of high-tech medical care can be ensured even in rural areas.
Endovascular surgery is a minimally invasive procedure that involves puncturing the skin and inserting a special wire into the arteries and vessels. The procedure is carried out under the control of an X-ray and allows you to perform the most complex manipulations with minimal health risks and complications. For example, install catheters to dissolve blood clots or turn off areas with aneurysms from the bloodstream. Such operations are performed by highly qualified surgeons — rare specialists who most often work in large hospitals in large cities.
Now scientists from The Massachusetts Institute of Technology presented a solution to this problem — a robotic system for performing endovascular interventions remotely. You can see how this will work in reality in the video in the MIT Joystick-operated robot press release could help surgeons treat stroke remotely - VM.
The doctor can be in another room or in another city and control the robot with a joystick. The robot is equipped with a magnet that ensures the accurate movement of the magnet-sensitive wire through the vessel.
The demonstration of the operation on models of silicone vessels representing complex bends of the arteries of the brain turned out to be promising.
Doctors were able to quickly and efficiently control the wire, bend around sharp corners and turns and get to the right areas. For example, the technology made it possible to remove blood clots and block aneurysms, as if this was done by a doctor present in the operating room.
It should be emphasized that in this way, scientists have provided additional benefits to doctors, since now they do not need to be exposed to radiation, which is necessary to control the operation process.

Scientists believe that the new robotic system will change global healthcare and solve one of its leading problems — reduce mortality from stroke and heart attack and reduce the number of disabilities. In the future, it is planned that a nurse will prepare a patient in an acute condition for surgery at a local hospital, and a doctor from anywhere in the world will do all the work with the help of a robot.
Earlier, another team of scientists came to the conclusion that vascular surgery after a stroke can reduce the risk of relapse by four times, so equipping hospitals remote from major cities, for example, with new robotic systems, can radically change the statistics of mortality from cardiovascular diseases around the world.
