Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
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.
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.
This chapter will go through the mechanism and working of light cables, cameras and
light sources used in laparoscopy
