The robot works with a 1.14mm nickel-titanium alloy needle (in the traditional method it is 1.18mm) that works like a mechanical pencil, following a curved path in the brain. This needle can be precisely steered by a robotic platform operating within a magnetic field created by a resonance scanner. The combination of these elements with compressed air makes it possible to advance one millimeter at a time without damaging other parts of the brain.
With this system, the surgery is less invasive and the recovery of the patient faster and less painful. They even managed to reduce costs by designing the system so that most of its components can be generated by 3D printing as shown in the image below.
The breakthrough promises, but has yet to be tested on humans or animals.
