Joystick Working Robot, How Can It Be Used In Surgery?
MIT engineers have developed a telerobotic system to help surgeons treat patients with strokes or aneurysms remotely. With a modified joystick, surgeons can operate on a patient remotely.
The MIT team predicts that the robotics system could be installed in smaller hospitals and remotely guided by surgeons trained in larger medical centers.
The system includes a medical-grade robotic arm with a magnet attached to its wrist. With a joystick and live imaging, the operator can adjust the direction of the magnet and manipulate the arm to guide a soft and thin magnetic wire along arteries and veins.
The researchers demonstrated the system in a "ghost," a transparent model with veins that replicate complex arteries of the brain. With just an hour of training, neurosurgeons were able to remotely control the robot's arm to get a wire through a labyrinth of veins to the target positions in the model.
The system can provide teleoperated endovascular treatment to patients during critical time after the onset of stroke.
