Consumers have been slow to buy into high-definition television (HDTV) despite the technology’s promise of sharper, brighter images. Now the makers of a prototype HDTV system are looking for a better reception from an audience a bit more demanding than your average couch potato: surgeons. The hope is that using the technology in endoscopic surgery could lead to quicker, more accurate surgeries with fewer complications.
Endoscopes allow surgeons to see into the body to perform complex surgical procedures, from repairing joints to removing cancerous lesions, through tiny incisions. Each endoscope has a thin tubular protrusion that can be threaded through the incision; the tube houses lenses or optical fibers that feed images from inside the body to an eyepiece, or to a camera that relays the picture to a monitor. Although surgeons perform hundreds of thousands of such procedures every year in the United States alone, they often lament the poor quality of video due to blurring and transmission artifacts.
Steven F. Palter, a surgeon at the Yale University School of Medicine, spurred electronics giant JVC to join with San Ramon, CA, medical optics company TTI Medical to make a mini-HDTV camera for endoscopic surgery. Recently, JVC developed a palm-sized HDTV camera-the world’s smallest-for microsurgery on tiny blood vessels and nerves. The next challenge was adapting the camera to an endoscopic viewing system.
