Brain surgery is famously difficult for good reason: When removing a tumor, for example, neurosurgeons walk a tightrope as they try to take out as much of the cancer as possible

And the surgery to implant the sensors was minimal. According to Thorvaldur Ingvarsson, an orthopedic surgeon and head of R&d at Ossur, the procedure took 15 minutes,
and each sensor required a single-centimeter-long incision. The tiny sensors (3 millimeters-by-80 millimeters) are powered by magnetic coils embedded in the socket--the cushioned,
#Handheld Device For Surgeons Could Turn off Pain A new handheld tool called the Chimaera will help surgeons find the right nerve with ease by giving them real-time feedback during operations.
This kind of device, its developers claim, will usher in a new age of surgical devices, making delicate nerve procedures easier for surgeons everywhere.
In recent years surgeons have been able to implant devices called neuromodulators that can stop pain
But surgeons have a hard time accessing nerves that are behind the eyes or the face because it's difficult to identify the right one among the jumble,
The Chimaera device helps surgeons identify and access specific nerves. When a surgeon holds the wireless wand-like device near a place where he plans to make an incision,
the Chimaera sends data about that spot to a computer where it is combined with information from a CT SCAN of the patient brain taken previously.
This information is compiled into a single X-ray-like image that the surgeon can see in real time with Google glass
and nerves that surround the place of the incision so that the surgical tool is as precise as possible.
the Chimaera can help the surgeon damage as little as possible on its way to the desired nerve,
where the surgeon can implant the neuromodulator device. Right now these most delicate procedures can only be conducted by a handful of surgeons worldwide, Reuters reports.
But the Chimaera could make neuromodulators so much easier to implant that they could become more commonplace.

"The primary goal of the technology is to make sure that the surgeon does not operate in the blind,
which allows a surgeon wearing specialized glasses to see cancer cells glowing.""What this does is conserve the healthy tissue
Chimaera is designed to make implanting neuromodulators to nerves much easier by integrating surgical sensing and implant delivery functions in one intelligent device.
enabling surgeons to identify critical structures, such as nerves and blood vessels. This combines with the intraoperative data from Chimaera's sensing technology to guide the surgeon to the precise location of a procedure,
helping to ensure the surgical device stays on a predetermined safe pathway. The real-time data generation is designed to be used in conjunction with optical wearable technology, such as Google glass.
This means a surgeon can literally'see'exactly where they are within the body at any point during an operation.
Once the target nerve has been reached the sensors also let the surgeon know, and the implant can then be deployed down the device.
Karger said their aim was to figure out how neuromodulators-measuring less than a centimeter in length-could be implanted as simply and quickly as possible.
