Signal words The following signal words are used throughout this manual:

Indicates an imminently hazardous situation which, if not avoided, will result in death or serious injury.

Indicates a potentially hazardous situation which, if not avoided, could result in death or serious injury.

Indicates a potentially hazardous situation which, if not avoided, may result in minor or moderate injury. It may also be used to alert against unsafe practices or potential equipment damage.

Dangers, warnings and cautions Follow the dangers, warning and cautions 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 an electric 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 contact may cause unintended current flow to the patient.  Do not prepare, inspect or use this equipment with wet hands.

Important Information - Please Read Before Use

•

Never install and/or operate in the following 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. Otherwise, an explosion or fire may occur.

•

Be sure to prepare another camera head to avoid that the examination must be interrupted due to equipment failure or malfunction.

•

This product may interfere with other medical electronic equipment used in combination with it. Before use, thoroughly confirm the compatibility of this instrument with all equipment to be used with it.

•

Do not use this product in any place where it may be subject to strong electromagnetic radiation (for example, in the vicinity of a microwave therapeutic device, MRI, wireless set, short-wave therapeutic device, cellular/portable phone, etc.). This may impair the performance of the product.

•

Be sure not to bring and/or pile up this instrument too close to other instruments to avoid an electromagnetic interference from them.

•

Electromagnetic interference may occur on this instrument near a portable device and a mobile RF communications equipment such as a cellphone marked with the following symbol:

Important Information - Please Read Before Use

Cardiac applications

8

•

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 60601-1: 1988 (included amendment 1,2), 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 metalic 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 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 video plug and its electrical contacts are completely dry before connecting the plug to the OTV-SP1C/OTV-SP1C-G/CV-180. 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.  Never use a clamp or forceps to attach the camera cable to another object. Doing so could damage the cable.

Chapter 3 Preparation and Inspection

3.3

Preparation of ancillary equipment •

To ensure safety, securely connect the power cord of the OTV-SP1C/OTV-SP1C-G/CV-180 and the light source to a hospital grade receptacle (wall mains outlet).

•

When using a non-medical video monitor or other ancillary equipment, always connect Olympus equipment via an isolation transformer.

Setup the OTV-SP1C/OTV-SP1C-G/CV-180, video monitor and other ancillary equipment as described in the OTV-SP1C’s/OTV-SP1C-G’s/CV-180’s instruction manual and the respective instruction manuals for each instrument.

3.4

Connecting the camera head to the 3CCD camera control unit OTV-SP1C/OTV-SP1C-G /EVIS EXERA II video system center CV-180 •

Never excessively bend, pull, twist, coil, squeeze or apply a crushing force to the camera cable. The camera cable could become damaged.

•

Make sure that the video plug and its electrical contacts are completely dry before connecting the plug to the OTV-SP1C/OTV-SP1C-G/CV-180. Wet contacts could cause the equipment to malfunction.

•

Do not connect or disconnect the video plug while the OTV-SP1C/OTV-SP1C-G/CV-180 is ON. Doing so may damage the electrical circuits inside the camera head.

•

After autoclaving, do not use the camera head until it has cooled down to room temperature. Otherwise, the video image may be impaired (“noise” etc.) (OTV-SP1H-NA-12E/12Q).

•

After autoclaving, let all components cool down to room temperature without additional cooling. Sudden changes in temperature may damage the instruments. Never rinse the instruments with cooled water for cooling (OTV-SP1H-NA-12E/12Q).
