video systems are generally used in gynecology, arthroscopy,
laparoscopic general surgery, thorascopy, urology and
main components of a video camera system are the endoscope,
coupler, camera head, camera cable, camera processor,
video monitors, light source, and light cord.
the picture above, the gray cord is the light cord.
The black one is the camera cord.

black box is the camera head.

long gray portion is the endoscope.
endoscope is a general term to describe any type of
scope. A laparoscope specifies areas of the abdominal
scopes have different diameters (3, 5, and 10 mm), lengths,
and angles of view (0 or 30 degree). General surgery
procedures use 10 mm, 30 degree laparoscopes.
this picture above, the left scope is a 30 degree and
the right is 0 degree.
video cameras are small, box like units that contain
a lens and either one or three light sensitive video
imaging chips called charged coupled devices (CCD's).
grooves of the camera need to be oriented to the ceiling
during laparoscopic procedures.
the camera head to the endoscope. It is important because
it contains the optical lens.
two dials to manipulate the images.
Blue dial is for zoom. Clockwise zooms IN. Counterclockwise
zooms OUT. This dial is generally not used during laparoscopic
gray dial is to focus the image.
power to the camera. Processes signals from the camera
to be read by the monitor. It has a few important switches

to compensate for low light conditions.
most important switches are white balance and gain.
light from the light box to the endoscope.
Make sure this is screwed on tight. Has a tendency to
longer the light cord, the less light will be delivered
to the scope. The usual length is 7.5-8 feet.
