Endoscope Care & Handling
FOR RIGID SCOPES
CLEANING:
The Endoscope has three optical surfaces that must be cleaned routinely to ensure both maximum transmis-
sion of illumination, and a high quality image. All should be cleaned with warm water and mild soap. If stains are still
present, a mixture (1:1) of methyl alcohol and acetone may be used. A fine woven cloth or lens tissue should be used
for cleaning. Dry with a soft woven cloth. By reflecting light off all optical surfaces, you can detect any foreign matter or
scratches that would degrade image quality.
Note:
Any foreign matter present on the fiber surface after cleaning may tend to burn and discolor the sur-
face when the high intensity lamp is in use.
Warning:
High-energy radiated light emitted from illuminating fiber at the distal end of the scope may give rise
to temperatures exceeding 41ºC within 8 mm in front of the scope. Burns may occur if you leave the tip of the
scope in direct contact with patient tissue or combustible materials. Lower the light source output when work-
ing in close proximity to the object.
Note:
To avoid fogging during surgery, the rear portion of the scope must be entirely free of moisture be-
fore attachment to the camera or coupler. Extreme heat from steam autoclaving and high intensity lamp
will cause debris on the optical surfaces to discolor, burn, and harden. The lock of the endoscope should
remain free of debris to ensure solid locking of components. Use a bristle brush with warm soapy water to
clean these components.
REMOVING DEPOSITS ON OPTICAL SURFACES:
Due to insufficient cleaning or foreign matter in steam, deposits may
develop on the three optical surfaces during the autoclaving process. Any foreign matter remaining on the optical sur-
faces will reduce the optical performance of the endoscopes and may lead to a cloudy picture. These deposits can easily
be removed using the biocompatible polishing past which is enclosed in the endoscope. To remove deposits, dab some
polishing paste onto a clean cotton tabbed swab. Press gently onto the optical surface to be cleaned and scrub the win-
dow in circles. Rinse the optical surfaces with tap water to remove any remaining polishing paste and clean the surfaces
as instructed in chapter 2.
Note:
Cleaning with polishing paste should not be part of your routine cleaning procedures and should
only be preformed when the range – as viewed through the scope – is cloudy.
CHEMICAL DISINFECTION AND STERIS PROCESS:
The Scope is immersible and should be disinfected using the process
obtained from the individual chemical manufacturer. Scopes are materially compatible with the Steris process. The en-
doscope should be rinsed after soaking with sterile water and dried with a sterile cloth.
STERILIZATION:
Be sure that the scope is cleaned thoroughly before sterilizing. The endoscopes should be sterilized or
disinfected in a container which secures the instrument in place. Be sure the needle portion does not experience any
force or stress which can destroy the delicate internal lenses.
GAS STERILIZATION:
Follow standard hospital procedures for gas sterilization. Place scopes separately from instruments
in a container approved for general use with gas sterilization (such as perforated metal tray), with gauze or loosely wo-
ven cloth inserts folded around each item and stabilized to avoid movement.
