Attach the 7 mm Extended Length Endoscope to the
camera coupler. Attach the light cable to the post on the
endoscope. Focus the endoscope on a gauze pad and
white balance the video camera as described below. Ensure
proper orientation of the camera head. It is important to
maintain correct orientation throughout the procedure.
Thread the Dissection Tip onto the distal end of the endo-
scope until the proximal edge of the Dissection Tip lines up
with the indicator etched on the endoscope shaft. (Figures 2
and 3)
Insert the endoscope with attached Dissection Tip through
the BTT. Ensure that the Endoscope Seal is on the BTT (it
comes packaged with this seal attached). (Figure 4)
proper White balancing
White balancing is the process by which the camera learns
what “white” is. This process sets the full range of color
through the camera.
To white balance the camera, attach the camera head and
fiber optic cables to the endoscope and hold a piece of
white gauze approximately 1.5 inches from the distal end of
the endoscope. (Figure 5)
Focus the camera and ensure that only white is visible.
Press the white-balance button from either the camera head
or camera box, depending on the camera system. Hold the
camera and endoscope still until the system indicates white
balance is completed.
