•

Never perform angulation forcibly or suddenly. Never forcefully pull or twist the angulated bending section. Patient injury, bleeding and/or perforation can result. It may also become impossible to straighten the bending section during use and/or to withdraw this instrument from the patient. Particular caution is required in the tracheal bifurcation region.

•

Never perform angulation control, suction control or insertion/withdrawal of the endoscope’s Insertion Tube without viewing the endoscopic image. Patient injury can result.

•

Never insert or withdraw the endoscope while the endoscope’s bending section is locked in position. When withdrawing the endoscope, the bending section should follow the form of the body cavity as much as possible. Otherwise, patient injury, bleeding and/or perforation can result. It may also become impossible to straighten the bending section during use and/or to withdraw this instrument from the patient.

LF-2/P/T OPERATION MANUAL

Important Information - Please Read Before Use

•

The shape and size of the nasal cavity and its suitability for transnasal insertion may vary from patient to patient. No endoscope, including this one, can always be inserted transnasally with all patients. Before proceeding, always be sure to confirm that transnasal insertion is possible with the patient. Otherwise, operator and/or patient injury can result or the endoscope could become lodged and be difficult to withdraw.

•

Transnasal insertion is accompanied by the risk of inflammation of the nasal cavity. If this happens, the nasal passage will be constricted, making it more difficult to withdraw the endoscope. In this case, do not use force to withdraw the endoscope because patient injury such as bleeding or perforation may result.

•

Transnasal insertion is accompanied by the risk of bleeding in the nasal cavity. Be sure to be prepared to deal with any bleeding. When withdrawing the endoscope, observe the inside of the nasal cavity to ensure that there is no bleeding. Even when the endoscope has been withdrawn without bleeding, do not allow the patient to blow his or her nose strongly because this could cause it to start bleeding.

•

Before transnasal insertion, apply the appropriate pretreatment and lubrication to the patient to enlarge the nasal cavity. Otherwise, operator and/or patient injury can result or the endoscope could become lodged and be difficult to withdraw. Otherwise, the treatment will have no effect. The effects of the pretreatment agent and lubricant will decrease the longer the procedure lasts. Apply the pretreatment agent or lubricant as required during the procedure – for example, when withdrawal seems to be difficult.

•

Transnasal insertion of the endoscope should be performed carefully. If resistance to insertion is felt, or the patient reports pain, stop insertion immediately. Otherwise, operator and/or patient injury can result or the endoscope could become lodged and be difficult to withdraw.

•

If it becomes impossible to withdraw the transnasally inserted endoscope, pull its distal end out of the mouth, cut the flexible tube using wire cutters and, after ensuring that the cut section will not injure the body cavity or nasal cavity of the patient, withdraw the endoscope carefully. Therefore, always prepare wire cutters in advance.

•

Do not touch the Light Guide immediately after removing it from the Light Source because it is extremely hot.

Important Information - Please Read Before Use

•

Although the illumination light emitted from the endoscope’s distal end is required for endoscopic observation and treatment, it may also cause alteration of living tissues such as protein denaturation of liver tissue and perforation of the intestines by inappropriate using. Observe the following warnings on the illumination.  Always set the minimum required brightness. The brightness of the image on a video monitor may differ from actual brightness at the distal end of endoscope. Especially, operating the electrical shutter function of a video system, pay attention to the brightness level setting of the light source. When a light source and a video system are compatible with the automatic brightness control function, be sure to use the function of the light source. The automatic brightness control function can keep the illumination light properly. Refer to the instruction manual of the light source and the video system for details.  Do not continue observation in proximity to tissue or keep the distal end of the endoscope in contact with a living tissue for a long time.  When discontinuing the use of the endoscope, be sure to turn the light source OFF or activate the light shield function (standby mode etc.) so that the endoscope does not irradiate unnecessary light.

•

If the endoscopic image dims during use, this may be a sign that blood or mucus is adhered to the light guide on the distal end of endoscope. Carefully withdraw the endoscope from patient and remove the blood or mucus in order to obtain optimum illumination and to ensure the safety of examination. If you continue to use the endoscope in such a condition, the distal end temperature may rise and cause mucosa burns. It may also cause patient and/or operator injury.

•

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

•

This instrument has not been designed to be used with Endo-Therapy Accessories. Using Endo-Therapy Accessories can damage the endoscope.

LF-2/P/T OPERATION MANUAL

Important Information - Please Read Before Use

•

Do not pull the Universal Cord. The Endoscope Connector will be pulled out from the output socket of the Light Source and the endoscopic image will not be visible.

•

Do not coil the Insertion Tube and Universal Cord with a diameter of less than 10 cm. Equipment damage can result.

•

Do not hit to the Distal End of the Insertion Tube or allow it to strike other objects. The objective lens surface of the Distal End is particularly fragile, and vision abnormalities may result.

•

Do not twist or bend the Bending Section by hands. Equipment damage may result.

•

Do not squeeze the Bending Section forcefully. The covering of the Bending Section may stretch or break and cause water leaks.

•

The eyepiece section cannot be removed. Do not attempt to rotate it by force.

Details on clinical endoscopic technique are the responsibility of trained specialists. Patient safety in endoscopic examinations and endoscopic treatment can be ensured through appropriate handling by the physician and the medical facility. Examples of inappropriate handling are given below. •

Using improperly reprocessed or stored instruments may cause patient cross-contamination and infection.

•

Applying prolonged suction with the Distal End in contact with the mucosal surface may cause bleeding or suction lesions.

•

Patient injury may be caused by: inserting or withdrawing the endoscope, applying suction without a clear endoscopic view; forcefully pulling, twisting or rotating the angulated Bending Section.

•

The endoscope has not been designed for use in retroflexed observation. Performing retroflexed observation in a narrow lumen may make it impossible to straighten the bending section and/or withdraw the endoscope from the patient.
