Philips develops minimally invasive surgery augmented reality navigation device
Release date: 2017-01-17
On the 13th local time, Philips said that the company is developing a new surgical system that will use augmented reality technology to guide surgeons to better open and minimally invasive spinal surgery. The system will combine the external and internal images of the patient in real time to assist the physician during the procedure.
Open spinal surgery often requires large incisions, and the surgeon needs to see and touch the patient's spine with the naked eye. Minimally invasive surgery through small incisions in the skin can better reduce blood loss and soft tissue damage, postoperative pain, and has an increasing trend in recent years. However, postoperative minimally invasive surgery limits visibility, so surgeons need real-time imaging and navigation systems to guide them.
According to the statement, Philips' platform will capture and perform patient 3D stereo imaging of the patient through low-dose X-ray acquisition. This also allows the surgeon to obtain a real-time view of the spine at the incision site. In addition, the system can also be used for minimally invasive skull and trauma surgery.
“This new technology allows us to obtain high-resolution 3D images of the patient's spine prior to surgery, designing the optimal surgical path in advance, and the system's fully automated augmented reality navigation will help us determine where to place the pedicle screw,†Lake Dr. Skúlason of Landspitali at Yakuk University Hospital praised. “We can also examine the patient's overall results directly in the operating room 3D without having to move the patient near the CT scanner, all without any radiation exposure to the surgeon, and this way for the patient The radiation dose is also minimal."
Preclinical research on the platform was announced in Spine in November. The surgeon placed 94 pedicle screws in four vertebrae and successfully placed 47 screws on one side of the spine using augmented reality surgical navigation while successfully placing the other screw on the other side of the spine. The study found that the overall accuracy of screw mounting was improved after applying Philips technology (85% vs. 64%).
Philips said that in the joint clinical research program, the augmented reality platform technology will be installed in the Philips hybrid operating room of 10 clinical partners.
