Augmented reality guides surgeons during spine and cranial surgery
An augmented reality system designed to guide surgeons through delicate minimally-invasive spinal procedures has been developed by Philips.
The system, which combines camera images of the outside of the patient with three-dimensional X-rays of the inside of the body, is designed to create a detailed path for the spinal surgeon to follow. This could help to improve surgical tool navigation and implant accuracy, as well as reducing procedure times.
Spinal procedures have traditionally been carried out using open surgery, in which a large incision is made in the body and the muscles moved aside in order to expose the vertebrae.
But this invasive procedure results in a lengthy recovery period and a considerable amount of pain for the patient, according to Ronald Tabaksblat, business leader of image-guided therapy systems at Philips.
However, replacing open surgery with minimally-invasive techniques is particularly difficult in the case of spinal procedures such as vertebrae fusion, as screws are inserted which must be positioned with sub-millimetre accuracy, said Tabaksblat.
