Dangers and Warnings
Follow the dangers and warnings given below when handling this instrument.
This information is to be supplemented by the dangers, warnings and cautions,
given in each chapter.
•
Failure to adhere to the following precautions may place the
patient and medical personnel in danger of electrical shock.
− When this equipment is used to examine a patient, do not
allow the metal parts of the endoscope or its accessories
to touch metal parts of other system components. This
instrument is electrically connected to metal parts of other
system components and such contact may cause
unintended current flow to the patient.
− Keep fluids away from all electrical equipment. If fluid
enters the unit, stop the operation of the equipment at
once and contact Olympus.
− Do not prepare, inspect or use this equipment with wet
hands.
•
Never install and/or operate the OTV-S6C in locations where:
− The concentration of oxygen is high.
− Oxidizing agents (such as nitrous oxide [N2O]) are
present in the atmosphere.
− Flammable anesthetics are present in the atmosphere.
•
Be sure to prepare another camera head to avoid that the
examination must be interrupted due to equipment failure or
malfunction.
•
Do not use the instrument in a place that is exposed to
radioactive rays, strong electromagnetic waves (e.g., the
vicinity of a microwave therapeutic device, MRI, wireless set,
etc.). Otherwise, harmful influence may occur to the
operation.

Cardiac Applications
6
•
Use only the devices listed in the “System Chart” for
endoscopic observation or treatment of the heart or areas
near the heart. Other combinations of equipment may cause
ventricular fibrillation or seriously affect the cardiac function
of the patient.
•
For cardiac applications, never support the endoscope with a
metal surgical arm that is not electrically isolated from the
ground. If not isolated, the endoscope will be connected to
the ground through the surgical arm and bed, and will
conduct unexpected leakage current, which may seriously
affect the cardiac function of the patient.
•
The use of medical devices not specifically designed for
cardiac applications may cause ventricular fibrillation or
seriously affect the cardiac function of the patient. As
specified by international standard IEC 601-1 (Amendment 2,
1995), any “Applied Part” used for observation or treatment
of the heart or areas near the heart must meet “TYPE CF
APPLIED PART” requirements for low electrical leakage
current. When using metal endoscopes for endoscopic
cardiac applications, the “Applied Part” requirements include
all devices directly connected to the endoscope, such as the
Light Guide Cable, Camera Head, and telescope holder.
Each of these devices must individually meet the “TYPE CF
APPLIED PART” requirements for leakage current limits if
they are to be used for cardiac applications.
•
The Olympus Light Guide Cables and Camera Heads listed
in the “System Chart (TYPE CF APPLIED PART)” which are
suitable for cardiac applications bear a
symbol.
•
The Olympus Surgical Holder for Telescope (SH-1) has an
electrically isolated arm structure that isolates the endoscope
from the ground. This design makes the SH-1 suitable for
cardiac applications.

Important Information — Please Read Before Use
Precautions against frozen or lost endoscopic images
•
If the endoscopic image unexpectedly disappears or a frozen
image cannot be restored during an examination,
immediately stop using the instrument and withdraw the
endoscope from the patient. Continued use of the endoscope
under these conditions may cause patient injury, bleeding
and/or perforation.
•
Follow the precautions given below. Otherwise, the
endoscopic image may disappear unexpectedly, or it may not
be possible to restore a frozen image.
− Never clean, disinfect, sterilize or store this instrument
together with sharp-tipped instruments (tweezers,
forceps, knives, etc.). These could scratch or tear holes in
the camera cable, which could allow water to penetrate
and damage electrical circuits inside the instrument.
− Do not drop the camera head or allow it to strike other
objects. Strong impacts could damage the electrical
circuits inside the instrument.
− Make sure that the water-resistant cap is attached to the
camera plug during cleaning and disinfection. Otherwise,
the electrical contacts may get wet, which could in turn
damage the instrument’s electrical circuits.
− Make sure that the camera plug and its electrical contacts
are completely dry before connecting the plug to the
OTV-S6C. Wet contacts could cause the equipment to
malfunction.
− Never excessively bend, pull, twist, coil, squeeze or apply
a crushing force to the camera cable. The camera cable
could become damaged.
− Do not use excessive force when wiping the external
surfaces of the camera cable. Otherwise, the camera
cable could become damaged.
− While the camera head is attached to the endoscope,
never attempt to lift the entire assembly by the camera
cable. Doing so could damage the cable.

Chapter 4 Operation
Chapter 4 Operation
The operator of this instrument must be a physician or medical personnel under
the supervision of a physician and must have received sufficient training in
clinical endoscopic technique. This manual, therefore, does not explain or
discuss clinical endoscopic procedures. It only describes basic operation and
precautions related to the operation of this instrument.
•
If an abnormal endoscopic image/function occurs and returns
to its normal condition by itself, the equipment has
malfunctioned. Continued use in such condition may cause
abnormality again and it may not be able to recover to normal
condition. In this case, immediately stop use and withdraw
the endoscope from the patient slowly. Continued use of
such equipment may cause patient injury, bleeding and/or
perforation.
•
If the endoscopic image on the video monitor should
unexpectedly disappear or freeze during an examination and
cannot be recovered, turn the OTV-S6C’s power switch OFF
and then ON again. If the image still does not appear,
immediately turn the OTV-S6C OFF. Disconnect the camera
head from the endoscope and slowly withdraw the
endoscope from the patient, while viewing through the
endoscope’s eyepiece. In addition, be sure to prepare
another camera head to avoid that the examination must be
interrupted due to equipment failure or malfunction.
•
Intense endoscopic illumination may cause mucosal burns.
When endoscopes are used with high intensity (e.g. Xenon)
Light Sources, they can concentrate intense light on a
relatively small area of the mucosal surface. Always use the
minimum level of illumination necessary for adequate
viewing. Whenever possible, avoid close, stationary viewing
and do not leave the Distal End of the endoscope close to
mucous membranes for a long time.
•
When you are using an endoscope or ancillary equipment
without an automatic brightness control, adjust the brightness
manually to maintain the minimum level of illumination
necessary for adequate viewing.
•
The risk of the thermal injury increases under the following
conditions:
CAMERA HEAD OTV-S6H-N/D/1N/1D
19
Page 24
Chapter 4 Operation
− Prolonged contact with or close, stationary viewing of the
mucosa.
− Passage of the endoscope through a narrow lumen (e.g.
esophagus, pharynx).
− Using high-intensity Light Sources (e.g. CLV-U40,
CLV-U20, CLV-S20, CLV-S30, CLV-S∗1, CLD-S,
CLV-F10, CLV-10, CLV, CLX, or CLX-F) at their maximum
output settings.
∗1
•
Not available in U.S.
Take the following precautions to reduce the risk of mucosal
burns:
− Always use the minimum level of illumination necessary
for adequate viewing. The filter supplied with high
intensity (e.g. Xenon) Light Sources may be used to
reduce brightness.
− Whenever possible, avoid close, stationary viewing.
− When the endoscope is not being used, always turn the
Light Source off.
20
•
When performing endoscopic treatment, be prepared to
perform open surgery as an emergency measure in the event
of a malfunction of the endoscope or other system
component (light source, camera control unit, camera head,
monitor, cables, insufflation unit, etc.).
•
While the camera head is attached to the endoscope, never
attempt to lift the entire assembly by the camera cable. Doing
so could damage the cable.
•
Never use a clamp or forceps to attach the camera cable to
another object. Doing so could damage the cable.
•
Be careful not to scratch the camera cable with a
sharp-tipped instrument.
