The laparoscope is the "camera" with only a diameter of 5-10mm (0.5-1cm) and in a straight rod. It uses a high intensity light, such as xenon or halogen, and 3-chip technology. It is inserted in the abdomen so that the surgical team can observe the inside of the abdomen on a high resolution video screen. The laparoscope is moved to direct the view seen. A video recorder can be used to record the surgery and photographs can be made with a video-printer (see diagram 1). There is also available three-dimensional display technology that provides depth perception and may help the surgeon to orient. Minilaparoscopes of diameters from 1.9 to 2.8 mm have also been developed and are renewing the interest in performing laparoscopy under local anesthesia. |
