A “SMART” needle with an embedded camera is helping doctors perform safer brain surgery.
The device was developed by researchers at the University of Adelaide in South Australia and uses a tiny camera to identify at-risk blood vessels.
The probe, which is the size of a human hair, uses an infrared light to look through the brain.
It then uses the Internet of Things to send the information to a computer in real-time and alerts doctors of any abnormalities.
The project was a collaboration with the University of Western Australia and Sir Charles Gairdner Hospital where a six-month pilot trial of the smart needle was run.
Research leader and Chair of the University of Adelaide’s Centre of Excellence for Nanoscale BioPhotonics Robert McLaughlin said researchers were also looking at other surgery applications for the device including minimally invasive surgery.
He said surgeons previously relied on scans taken prior to surgery to avoid hitting blood vessels but the smart needle was a more accurate method that highlighted their locations in real-time.
“There are about 256,000 cases of brain cancer a year and about 2.3 per cent of the time you can make a significant impact that could end in a stroke or death,” he said.
“This (smart needle) would help that … it works sort of like an ultrasound but with light instead.
“It also has smart software that takes the picture, analyses it and it can determine if what it is seeing is a blood vessel or tissue.\\\\\\\"
