One blue surgical drape at a time, the patient disappeared, until all that showed was a triangle of her shaved scalp. “Ten seconds of quiet in the room, please,” said David J Langer, the chairman of neurosurgery at Lenox Hill Hospital in Manhattan, part of Northwell Health. Silence fell, until he said, “OK, I’ll take the scissors.” His patient, Anita Roy, 66, had impaired blood flow to the left side of her brain, and Langer was about to perform bypass surgery on slender, delicate arteries to restore the circulation and prevent a stroke. The operating room was dark, and everyone was wearing 3-D glasses. Lenox Hill is the first hospital in the United States to buy a device known as a videomicroscope, which turns neurosurgery into an immersive and sometimes dizzying expedition into the human brain. Enlarged on a 55-inch monitor, the stubble on Roy’s shaved scalp spiked up like rebar. The scissors and scalpel seemed big as hockey sticks, and popped out of the screen so vividly that observers felt an urge to duck. “This is like landing on the moon,” said a neurosurgeon who was visiting to watch and learn. The equipment produces magnified, high-resolution, three-dimensional digital images of surgical sites, and lets everyone in the room see exactly what the surgeon is seeing. The videomicroscope has a unique ability to capture “the brilliance and the beauty of the neurosurgical anatomy,” Langer said. He and other surgeons who have tested it predict it will change the way many brain and spine operations are performed and taught. “The first time I used it, I told students that this gives them an understanding of why I went into neurosurgery in the first place,” Langer said. But there is more to it than just the gee-whiz, Imax factor. The shared viewing makes 3-D surgery an ideal teaching tool. In addition, Langer and other doctors say the device is smaller and much less cumbersome than standard surgical microscopes and provides better light. It can easily be moved and angled to show bits of anatomy that surgeons would otherwise have to twist and crane their necks to see. Two surgeons on opposite sides of the table can work together easily. Standard surgical microscopes are enormous and require a complicated draping process to ensure sterility. Not so with the new videomicroscope, which is covered with just a sleeve that Langer said can be slipped on like a condom. Neurosurgery can take many hours, which surgeons operating with magnifying loupes or microscopes often spend looking down, their necks bent. As the clock ticks, discomfort becomes pain, and over the years chronic injury to the neck and back can be a career-ender for some surgeons. The new device lets them operate while looking straight ahead at the 3-D screen, using the image to guide their hands. “I don’t think there’s any doubt that it’s going to be valuable,” Langer said. But, he added, “In the eyes of someone who’s more conservative and who’s not as willing to try new things, they may not get over the hump and be willing to do it.” The device at Lenox Hill is called the Orbeye, made by Somed — a joint venture of Olympus and Sony — and marketed by Olympus.
Langer has received consulting fees from the company.The equipment produces magnified, high-resolution, three-dimensional digital images of surgical sites A number of other medical centres in the United States have also been testing the Orbeye. Charles L Branch, chief of neurosurgery at Wake Forest Baptist Medical Center in Winston-Salem, N C, said his first patient with it was a red bell pepper. “I cut a hole and plucked seeds out of the center,” he said. “I wanted to make sure you could see down a tubular opening. It worked really well.” He quickly moved on to humans, and has used the equipment in about 20 spine surgeries, all minimally invasive and performed through a tube. “The very first case, I almost felt like I was getting carsick,” he said. But it was a fleeting sensation, and he adapted quickly. “It’s really cool,” Branch said. “It’s like being in the Imax. It lets not only the surgeon but everybody else in the room see what’s going on. Instead of having to lean up against the microscope, and strain my neck or back, I can stand comfortably, look at the big screen in front of me and work with my hands.” He described the camera as “a Coke can on a stick over my shoulder,” easy to move, adjust and angle into positions not possible with a microscope. There are 10 neurosurgeons in his department, Branch said. “Everyone that’s used it has seen some potential benefit, but not everyone has decided they want to use it in every case.” He said that the company had lent an Orbeye to his hospital for surgeons to try out, and that he hoped the hospital would buy “a handful” of the devices, more than one because so much surgery is done there. Branch said he had no financial ties to the company. “I don’t think it’s a gimmick,” he said. “I believe it will be widely adopted fairly quickly.” Mark Miller, a spokesman for Olympus, said the Orbeye’s pricing would be similar to that of standard surgical microscopes, which range from $200,000 to $1 million. The system that Lenox Hill bought cost about $400,000, Langer said. Other companies are also trying to enter the market. “I think we’ll see three or four competitive products pop up,” Branch said. “That will make the technology less expensive.” Bob S Carter, chief of neurosurgery at the Massachusetts General Hospital, said using the Orbeye was like having “Superman eyes,” but added that his hospital was also evaluating other devices and had not yet decided which to buy. The technology, he said, is “the way of the future.” Roy, a retired administrative assistant who lives in the Bronx, first noticed troubling symptoms in 2015: episodes of weakness in her right hand, and trouble speaking. Tests at a local hospital ruled out a stroke. But the occasional episodes continued, and in July 2017, while recovering from heart surgery at Lenox Hill, she had a seizure. Her operation, on December 15, was the first bypass Langer performed with Orbeye, though he and his colleagues had used it for other operations. This type of bypass is one of the most difficult neurosurgical operations, and requires stitching together arteries that are only a millimetre or so in diameter. Colleagues say Langer is one of the few surgeons in the world with the skill and experience to perform it well.
