UConn surgeons recently did their 100th surgery using the augmented reality system, which is recommended for all but the most basic surgeries, especially for implants such as pedicle screws, Moss said. “So with this navigation technology, I can do more complex surgeries with less exposure.” The navigation is necessary because “you have much less direct visualization of the spine,” Moss said. In the minimally invasive surgery he performs, “you’re making very small incisions and, instead of taking muscle off, you’re just kind of spreading it and getting down to the bone and then doing your work,” he said. ![]() Moss doesn’t usually open up the back, which requires moving the muscles to be able to see the spine. “So it’s OK if there’s some movement after you do the scan.” The tracker usually is attached to the pelvis “so it moves together with the patient,” he said. “You can move the patient because the tracker will move as well.” If the patient needs to be moved during surgery, “the tracker moves with them, so it’s OK,” Moss said. … I’m staring right at while I’m also staring at my patient.” “Now I never have to look away from the patient. “So not only I can see through them, but it overlays information on top of that, which is why this is augmented reality,” Moss said. The view through a headset showing via augmented reality from a CT scan what the surgeon is operating on. And basically the helmet has glasses that come down over my glasses,” onto which the CT scan is projected. “And then it knows where my head is in space because of the helmet. “The system knows where the patient is because there’s a tracker on it,” he said. Wearing the headset, Moss can keep his attention on the patient. “So you’re doing surgery, but you have to keep looking up and looking up and trying to say, OK, am I in the right place? Where am I? How does it look? And it’s a little distracting.” “In the traditional systems, this was on a computer screen somewhere,” he said. “And then every instrument you use also has a tracker on it that the camera can see.”Ī CT scan is taken of the patient on the operating table, which is then projected in the headset, “so you get very detailed information of where you are in somebody’s spine,” he said. The technology uses a camera and trackers attached to the patient “so that the camera knows or the computer system attached to the camera knows where that patient is in space,” Moss said. ![]() “But having a navigation technology helps us do it in a safer manner.” We’ve been doing that for years,” he said. “We know how to put screws in people’s spines.
