Philips has announced both the expanded rollout of its augmented reality (AR) surgical navigation solution—ClarifEye—to Japan, as well positive results in the first patients treated by the International University of Health and Welfare, Mita Hospital (Tokyo, Japan) using this 3D AR solution.
Installed on a Philips interventional X-ray system in a hybrid operating room at Mita Hospital, ClarifEye helped the hospital’s orthopaedic surgeon, Ken Ishii, to successfully treat patients with spinal stenosis and scoliosis via minimally-invasive image-guided procedures.
ClarifEye combines 2D and 3D visualisations at low X-ray dose with 3D AR navigation into one system. According to Philips, it enables surgeons to define and navigate critical trajectories for precise device placement while avoiding damage to fragile neurological and vascular structures close to the patient’s spine.
“The benefit of performing spine surgery in the hybrid operating room includes the ability to acquire 3D computed tomography (CT) images at low dose, having a lot of space, and being able to use the large monitor,” said Ishii. “The addition of a new navigation system helps to create an even safer surgical environment. Compared to existing navigation systems, ClarifEye has no reference frame-related errors, and it’s wonderful that it achieves real time imaging with pedicle segmentation. ClarifEye is a new technology that truly offers minimally invasive surgery for patients and clinical staff.”
Karim Boussebaa, general manager of image guided therapy systems at Philips, added: “Mita Hospital’s positive experience of using ClarifEye to deliver the benefits of minimally invasive therapy to its spine patients mirrors that of hospitals in Europe and the Middle East who also recently adopted the system.
“ClarifEye adds a new dimension in surgical precision for patients. It is a great example of how we are innovating procedures and helping clinicians to deliver on the quadruple aim of better health outcomes, improved patient and staff experiences, and lower cost of care.”
ClarifEye’s live-video computer vision and AR technology uses non-invasive position markers applied to the patient’s skin to track patient positioning and overlays the resultant live video onto a 3D cone-beam CT of the patient’s spinal column. It enables surgeons to visualise the outside and inside of the patient in the same image, together with the planned and real-time trajectory of a Philips ClarifEye needle, without the need for live X-ray imaging. The system eliminates the cumbersome reference frames used by other systems, giving surgeons unimpeded access to the patient, the company adds.
