"Chimera" will help neurosurgeons
A new device for neurosurgeons helps to navigate the human body using augmented reality

Cambridge Consultants has developed a technology that, with the help of augmented reality, can guide a neurosurgeon's hand, showing exactly which nerves and vessels he is working with. The device called Chimaera will serve as a guide for the doctor – by directing it to the right part of the organ, the surgeon will be able to see its insides in all details.
Americans have a saying "well, it's not neurosurgery" – when they want to say that some action is not very difficult. Indeed, neurosurgery is a non–trivial process. There are several reasons for this – the work of the nervous system is not 100% studied, the small size of the nerve pathways.
Today, surgeons have unique tools – for example, a "magic wand"-an electroscalpel, which cuts tissues more easily, and is able to automatically cauterize tissue right on the go, reducing blood loss.
ElectroscalpelThe nerve center, located where the base of the skull meets the upper spine, is most easily accessed through the oral cavity.
But the problem is that the nerve pathways are not only similar to each other, but also similar in appearance to the vessels. It is easy to cut them, but choosing the right one without hitting other important ones is much harder, this is the art and skills of the surgeon.
The Chimaera device will come to the rescue in these cases. The surgeon directs it to the desired area of tissue, and Chimaera uses a combination of data obtained before the operation (for example, MRI results) with information received in real time from sensors, and shows the surgeon a three-dimensional model of the organ he is working on. The device tells you which vessels to avoid, where to move the scalpel and when the goal becomes achieved.
A new device for Chimaera surgeons
"This new surgical device has the potential to change the surgical process by providing the surgeon with a new dimension of data that is easy to use," says Simon Karger, head of surgical product development at the company. "It will allow more surgeons to perform complex operations with less risk and better outcomes for patients."
