Nanotech robot targets keyhole neurosurgery
While recent rapid advances in neurosurgery have allowed medical teams to target areas of the brain with minimal invasiveness, there has been a problem with the amount of visibility that keyhole surgery of this kind allows.
The size of the openings left by probes, needles or catheters (used in keyhole procedures) are on a scale that can limit the surgeons' manoeuvres.
Now, however, a miniature robot developed by a researcher at the Hebrew University of Jerusalem could offer a solution.
The tiny device works by guiding surgical procedures with an unprecedented level of accuracy and safety.
Traditional keyhole brain surgery, working from CT or MRI images, leaves the possibility of misplacement of surgical instruments which can result in a hemorrhage and severe complications.
