Currently doctors are using robotic systems guided by magnetic resonance imaging (MRI) to perform the surgery. But the process cannot be done simultaneously while the MRI is in use due to interference from electromagnetic motors commonly used in robots. Doctors must often move a patient in and out of the MRI scanner to manually adjust the positioning of a needle. The needle needs to be inserted into the brain before proceeding.
The new device was designed and developed by a university of Hong Kong mechanical engineering team and tested by neurosurgeons from the Chinese university. After five years of research and more than a dozen prototypes, the problem was resolved by developing a hydraulic powered robotic system. Non metallic Robots are being also developed to take care of magnet of MRI machine. “This robot can accurately control and position the needle without affecting the MRI…
