NEW YORK — For some heart surgeons, regular TV just doesn't show enough blood and guts.
That's why a team of cardiac surgeons at New York University Medical Center has installed a high-definition camera and TV monitors in their operating room, becoming the first in the world to use this consumer technology for surgical purposes.
In front of several monitors showing close-ups of beating hearts, NYU's Dr. Eugene Grossi talked about the special television. It offers "a dynamic range in color" and a high-resolution image that allows the doctors to see features of the heart they couldn't even see with the naked eye, said Grossi, the director of the hospital's cardiac surgical research laboratory.

The surgeons use the camera to "see" inside the heart during endoscopic surgery, the minimally invasive procedure that has been gaining in popularity over traditional open-heart surgery in the past several years.
Why? It's supposed to minimize physical trauma because it involves making small incisions in the chest wall between the ribs instead of sawing open the sternum, as in open-heart surgery. Surgeons insert long, chopstick-like instruments into two of these holes and a camera into the other.

"The minimally invasive surgery that came out four or five years ago changed the way we do surgery," said Dr. Aubrey Galloway, director of surgical research at NYU. "Now we can do procedures in 85 or 90-year-olds that we couldn't do before because we had to split the sternum open."
But a continuing technical problem has been poor resolution in the images of the heart: Heart cavities blur into blackness and instruments disappear, adding to the surgical guesswork involved.

"Before, nobody could see," Galloway said. Now [with HDTV] everybody can see."
Robots and Resolution
The NYU heart surgery team set up its SONY HDTV camera in conjunction with Aesop, a voice-activated operating room robot.
The robot holds the camera and is directed with a simple voice command to zoom in or out of the patient's chest, or move to the right or left, up or down.

Large high-definition monitors hang from the ceiling of the operating room, but the surgeons mainly rely on tiny head-mounted monitors that go over their surgical glasses.
With this setup, the surgeons can see better and they can command the robot to take a picture of the operation or record it on video. These images can be used in post-surgical evaluation as well as in teaching fellows and residents.
The Sony HDTV camera is the first one small enough to be mounted in an OR.

"The benefit of HDTV is it's a great teaching tool," said Galloway. "We can disseminate information more quickly."
And then there's telemedicine. If a surgeon in a remote location is able to transmit a very clear image of the operating area to a specialist in a major hospital, the specialist can guide the surgeon in real time.
"We don't know exactly where all this is going," said Galloway. "When so many technologies are merging at once, it's hard to predict which one is going to improve our ability to do something."
Meanwhile, the NYU team says its sharper images are making the work easier. "We have to create a workspace in the chest and we want to make as small the amount of trauma as possible," Grossi said. "The visuals of HDTV enable that to happen.", 百拇医药(Marian Jones)
