Optical Devices

Abstract

Optical devices in laparoscopic surgery comprised a telescope (0-30-45 degree telescopes), a light source, a light cable, a camera, and a monitor. All play an essential role from the beginning to the end of the procedure. The outcome of a suitable laparoscopic procedure depends on optical devices. The telescope used may have 0-3-45 degree view. The light source can be Helium or xenon. Xenon is costly but resembles natural light more, giving a good in vivo view. <br><br>Optical fibers carry light into the abdomen, and the rod lens mechanism moves images to the camera and then to monitor, to result in a successful procedure. <br><br>This chapter will go through the mechanism and working of light cables, cameras and light sources used in laparoscopy
