Warnings and cautions

Follow the warnings and cautions given below when handling this instrument. This information is to be supplemented by the warnings and cautions given in each chapter.

•After using this instrument, reprocess and store it according to the instructions given in the endoscope’s companion reprocessing manual whose cover lists the model of your endoscope. Using improperly or incompletely reprocessed or stored instruments may cause patient cross-contamination and/or infection.

•Before endoscopy, remove any metallic objects (watch, glasses, necklace, etc.) from the patient. If performing high-frequency cauterization becomes necessary while the patient wears a metallic object, it may cause burns on the patient in areas around the metallic object.

•Do not strike, bend, hit, pull, twist, or drop the endoscope’s distal end, insertion tube, bending section, control section, universal cord, or endoscope connector of the endoscope with excessive force. The endoscope may be damaged and could cause patient injury, burns, bleeding and/or perforations. It could also cause parts of the endoscope to fall off inside the patient.

•When performing transnasal insertion of the GIF-N180, please follow the cautions below.

−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.

6	EVIS EXERA II GIF/CF/PCF TYPE 180 Series OPERATION MANUAL

Important Information — Please Read Before Use

−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 Even when the endoscope has been withdrawn without bleeding, do not allow the patient to blow his or her nose strongly because this could cause it to start bleeding.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. When applying a pretreatment agent through a tube, insert the tube into the same path as the path planned for the endoscope insertion. 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.

•Never perform angulation control forcibly or abruptly. Never forcefully pull, twist or rotate the angulated bending section. Patient injury, bleeding and/or perforation can result. It may also become impossible to straighten the bending section during an examination.

EVIS EXERA II GIF/CF/PCF TYPE 180 Series OPERATION MANUAL

Important Information — Please Read Before Use

•Never insert or withdraw the endoscope’s insertion tube while the bending section is locked in position. Patient injury, bleeding and/or perforation can result.

•Never perform flexibility adjustment, operate the bending section, feed air or perform suction, insert or withdraw the endoscope’s insertion tube, or use endo-therapy accessories without viewing the endoscopic image. Patient injury, bleeding and/or perforation can result.

•Never perform flexibility adjustment, operate the bending section, feed air or perform suction, insert or withdraw the endoscope’s insertion tube, or use endo-therapy accessories while the image is frozen. Patient injury, bleeding and/or perforation can result.

•Regardless of the flexibility of the endoscope’s insertion tube, never insert or withdraw the insertion tube abruptly or with excessive force. Patient injury, bleeding and/or perforation can result.

•Never insert or withdraw the endoscope’s insertion tube, use endo-therapy accessories while the image is magnified. Patient injury, bleeding and/or perforation can result (only when using the image magnification of the video system center CV-180).

•Do not touch the light guide of the endoscope connector immediately after removing it from the light source because it is extremely hot. Operator or patient burns can result.

•When the endoscopic image does not appear on the monitor, the CCD may have been damaged. Turn the video system center OFF immediately. Continued power supply in such a case will cause the distal end to become hot and could cause operator and/or patient burns.

•If it is difficult to insert the endoscope, do not forcibly insert the endoscope; stop the endoscopy. Forcible insertion can result in patient injury, bleeding and/or perforation.

•When combining the endoscope with a splinting tube, there is the risk of perforation or bleeding due to entanglement of the mucous membrane, or of the tube to becoming separated from the endoscope and remaining in the body. Before use, be sure to read the instruction manual for the splinting tube to fully understand its characteristics.

8	EVIS EXERA II GIF/CF/PCF TYPE 180 Series OPERATION MANUAL

Important Information — Please Read Before Use

•For reasons described below, do not rely on the NBI 1 imaging modality alone for primary detection of lesions or to make a decision regarding any potential diagnostic or therapeutic intervention.

−It has not been demonstrated to increase the yield or sensitivity of finding any specific mucosal lesion including colonic polyps or Barrett’s esophagus.

−It has not been demonstrated to aid in differentiating establishing the presence or absence of dysplasia or neoplastic changes within mucosa or mucosal lesions.

1 NBI stands for Narrow Band Imaging. For more details, refer to the instruction manual of the CV-180.

•Do not pull the universal cord during an examination. 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 or universal cord with a diameter of less than 12 cm. Equipment damage can result.

•Do not touch the electrical contacts inside the electrical connector. CCD damage may result.

•Do not apply shock to the distal end of the insertion tube, particularly the objective lens surface at the distal end. Visual abnormalities may result.

•Do not twist or bend the bending section with your 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.

•Turn the video system center OFF before connecting or disconnecting the videoscope cable from the electrical connector on the endoscope. Turn the video system center ON or OFF only when the videoscope cable is connected to both the video system center and the electrical connector on the endoscope. Failure to do so can result in equipment damage, including destruction of the CCD.

•The endoscope’s remote switches cannot be removed from the control section. Pressing, pulling or twisting them with excessive force can break the switches and/or may cause water leaks.

Examples of inappropriate handling

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 described below;

•Over-insufflating the lumen may cause patient pain, injury, bleeding and/or perforation.

•Applying suction with the distal end in prolonged contact with the mucosal surface, with higher suction pressure than required or with prolonged suction time may cause bleeding and/or lesions.

•The endoscope has not been designed for use in retroflexed observation in parts of the body other than the stomach. Performing retroflexed observation in a narrow lumen may make it impossible to straighten and/or withdraw the endoscope. Retroflexed observation in parts of the body other than the stomach should be performed only when the usefulness of doing so is determined to be greater than the risk that is posed to the patient.

•Inserting, withdrawing and using endo-therapy accessories without a clear endoscopic image may cause patient injury, burns, bleeding and/or perforation.

•Inserting or withdrawing the endoscope, feeding air, applying suction or operating the bending section without a clear endoscopic image may cause patient injury, bleeding and/or perforation.
