Handling Instructions

Handling Damage to the Flexible Video-Uretero-Renoscope resulting from incorrect operation­is not covered by the  Note: manufacturer’s warranty.

Operating The following instructions outline the correct operation of the Flexible Video-Uretero-Renoscope and the corresponding accessories. Suitable accessories for your Flexible Video-Uretero-Renoscope, such as biopsy forceps, can be found in the UROLOGY catalog or excerpts from this manual.

Holding the Flexible Video-Uretero-Renoscope Correctly Grip the handle of the Flexible Video-Uretero-Renoscope in your left or right hand, as shown in the picture. With this kind of control grip, the Flexible Video-Uretero-Renoscope can be operated with one hand.

Handling the Shaft CAUTION: Do not carry the Flexible Video-Uretero-Renoscope by the shaft. Do not pull, clamp or twist the shaft of the Flexible Video-Uretero-Renoscope. CAUTION: The shaft of the Flexible Video-Uretero-Renoscope must never be kinked or coiled up too tightly. It is best to suspend the shaft of the Flexible Video-Uretero-Renoscope by securely holding the handle in a vertical position. Warning: Applying lubricant to the lens may cloud the image and interfere with normal scope operation. Use a suitable water-soluble lubricant (e.g. Surgilube) for the distal section of the insertion shaft.­­Observe the lumen the entire time during use. If you lose your orientation, pull the shaft back slightly, in the neutral position, until vision is restored. If during use the image fails, is disturbed, becomes blurred, or if vision in general is impeded, put the deflection mechanism into the neutral position and slowly pull the shaft of the Flexible Video-Uretero-Renoscope out of the patient’s body. If the Flexible Video-Uretero-Renoscope is used in the patient after the image has failed or when there is interference, this may result in a serious injury to the patient.

Handling Instructions

Handling the Deflection Mechanism

 Note: The neutral position of the distal tip is straight, without any deflection. Warning: Accessories must only be inserted into the instrument channel of the Flexible Video-Uretero-Renoscope with the distal tip in the neutral, non-deflected position. The deflection lever must never be operated with force or abruptly to avoid injuring the patient or damaging the device. Warning: Before removing the Flexible Video-Uretero-Renoscope from the patient, the distal tip of the Flexible Video-Uretero-Renoscope must be put into the neutral position, otherwise injuries to the patient or damage to the instrument may occur. Warning: If the distal tip can no longer be properly controlled via the deflection lever, or if the deflection mechanism develops any other fault, the Flexible Video-Uretero-Renoscope must not be used. Warning: If a functional defect occurs during use on the patient, discontinue use immediately. Put the distal tip of the Flexible Video-Uretero-Renoscope into the neutral, non-deflected position and remove the Flexible Video-UreteroRenoscope slowly and carefully from the patient. CAUTION: The resistance that can be felt when deflecting the tip using the deflection lever increases as the angle of deflection increases. Actuate the deflection gently, without any sudden movements, as far as the limit stop allows. CAUTION: Do not use force to actuate the deflection lever, to avoid either injuring the patient or damaging the instrument. The distal tip can be deflected 270° upward or downward by continuously actuating the deflection lever slowly and carefully. The distal end will deflect in accordance with the direction of actuation. Before use, the user must always have full control over the deflection and must develop a feel for the deflection mechanism and in particular for the neutral position.

Handling Instructions

Handling the Accessories CAUTION: Only use flexible accessories (forceps, cleaning brushes etc.) from KARL STORZ. Accessories from other manufacturers may damage the Flexible Video-Uretero-Renoscope. CAUTION: Only introduce the instruments into the proximal port of the Flexible Video-Uretero-Renoscope. Warning: When HF electrodes or laser probes are used, it must be ensured that power is not applied until the active parts have emerged from the instrument channel and are in the user’s field of view, and the site of the operation is clearly recognizable. Activation in the instrument channel may lead to serious injury to the patient and damage the Flexible Video-Uretero-Renoscope. Warning: When HF electrodes or laser probes are used, it must be ensured that power is only applied when there are no flammable gases in the operating field or in the proximity of the Flexible Video-Uretero-Renoscope. CAUTION: Do not force accessories through the working channel to avoid damaging the device. It should be possible to move the accessory easily, without any hindrance through the entire channel. CAUTION: Do not introduce any accessory into the Flexible Video-Uretero-Renoscope when the distal tip is deflected. CAUTION: Inserting sharp-tipped accessories into the instrument channel may damage the Flexible Video-Uretero-Renoscope. CAUTION: The instrument channel is not designed for removal of tissue and/or foreign bodies. Remove the tissue or foreign bodies from the patient by removing the entire endoscope.
