Augmented Reality Navigation Streamlines Surgical Workflow – Surgical Techniques

An advanced surgical planning and screw placement system combines real-time imaging and augmented reality (AR) navigation.

The ClarifEye System from Royal Philips (Philips; Amsterdam, The Netherlands) is designed to merge low dose X-ray 2D and 3D visualizations with 3D AR navigation into one system. This allows surgeons to define and navigate the critical pathway using real-time guidance for precise device and screw placement in open and minimally invasive spinal procedures. ClarifEye is intended for use in conjunction with the Azurion Hybrid Operating Room (OR), into which it is fully integrated.

ClarifEye uses four high-resolution video cameras located in the arch and the Flat Panel Detector (FPD) to automatically detect non-invasive patient markers placed to increase the surgical field. Live video images provided by the cameras are superimposed on the 3D cone beam computed tomography (CBCT) scan used for pre-surgical planning. The system can then view the tip of the ClarifEye needle as it travels along the intended path to the vertebral anatomy, and until the screw is placed.

“We are delighted that international access to ClarifEye is expanding and that more hospitals and patients can directly benefit from it,” said Karim Boussebaa, Managing Director Image Guided Therapy Systems at Royal Philips. “ClarifEye adds a new dimension to surgical precision for patients. This is a great example of how we innovate in procedures and help clinicians achieve the fourfold goal of better health outcomes, improved patient experience, staff satisfaction and costs. inferior care.

“The new technology from Philips allows us to perform less invasive procedures and achieve better outcomes for patients with spinal diseases,” said Ahmed Al Jahwari, MD, head of the department of orthopedics and spine surgery at the armed forces hospital (Muscat, Oman). “With the high quality of intraoperative cone beam CT imaging and the positioning flexibility of the ClarifEye system, we can ensure that the implants are in place, reducing postoperative CT scans to verify implant placement. . “

Many conditions of the spine have traditionally been “open surgery,” where surgeons manually manipulate the patient’s spine to position implants and pedicle screws. As technology has advanced, there has been an evolution towards the use of minimally invasive techniques that minimize blood loss and soft tissue damage and, therefore, reduce postoperative pain. Intraoperative image guidance increases clinical accuracy and improves outcomes, with patients undergoing fewer revision surgeries.
