Handling Instructions
To ensure the long lasting quality of the flexible cystoscope, please follow the handling instructions described below. 1.
To prevent breakage, the flexible cystoscope should be supported by firmly grasping the handle. Never handle the flexible cystoscope by the flexible shaft or the distal end alone. Always pick up the flexible cystoscope by the handle first, then provide secondary support for the flexible shaft.
2.
To prevent inadvertent damage to the flexible cystoscope, KARL STORZ recommends placing the flexible cystoscope and accessories on a separate sterile Mayo stand or table away from the other endoscopic and standard surgical instruments being used during a procedure.
3.
When not in use, the flexible shaft of the instrument should be in a neutral, nondeflected position.
4.
Do not operate the deflection control lever with excessive force.
5.
Carefully protect the distal objective lens from damage: Never use the tip of the flexible cystoscope to dislodge or move objects.
CAUTION: Care should be taken during the passage of ancillary instruments through the working channel. Do not attempt to pass accessories when the distal tip of the flexible cystoscope is deflected at an extreme angle. 6.
Keep the distal tip of any electrode, laser fiber, probe or other ancillary device in the field of view at all times.
7.
Irrigation flow diminishes with accessory insertion and forced irrigation with a syringe may be necessary. Avoid excessive irrigation pressure.
8.
Prior to each use, inspect any insulated ancillary devices to ensure there are not splits, cracks, holes, burn marks, or other imperfections to the insulation. Do not use ancillary devices with visible signs of damage.
9.
Never kink or severely bend the shaft of the flexible cystoscope. The shaft and light carrier bundles may be damaged.
CAUTION: Avoid bending the strain relief at any sharp angle, as undue stress may be placed on the shaft and damage to the instrument may result. Warning: Before removal from the patient, the distal tip of the flexible cystoscope must be returned to the neutral (nondeflected) position to prevent damage to the instrument and/or injury to the patient. To return to the neutral position, turn the control lever to the middle position. 10. Handle the flexible cystoscope with care. Mishandling of the flexible cystoscope, particularly at the distal end, may result in damage. 11. When cleaning and sterilizing the flexible cystoscope and accessories, KARL STORZ recommends that the flexible cystoscope be handled separately from other instruments. 11
Inspection Before Use
CAUTION: Do not autoclave the flexible cystoscope. 12. Store the flexible cystoscope either in the sterilization tray specific to the flexible cystoscope or hanging suspended in the appropriate KARL STORZ wall rack specific to the flexible cystoscope. Warning: Do not store endoscope in its shipping case. Since the packing case does not allow adequate ventilation and will retain moisture when closed. Use the packing case only to ship the endoscope back to KARL STORZ. CAUTION: Do not store the flexible cystoscope at temperatures greater than 50° C (122° F).
Inspection Before Use The flexible cystoscope should be thoroughly inspected immediately upon arrival and prior to each surgical procedure. The following parts require inspection: Working Shaft: Check the entire surface of the working shaft for any abnormal conditions or damage, such as dents, cuts, wrinkles, or tears. Any indentation in the flexible shaft of the flexible cystoscope can cause damage to its internal mechanisms. DO NOT USE ANY FLEXIBLE CYSTOSCOPE WITH OUTWARD SIGNS OF DAMAGE. CAUTION: The distal tip of the flexible cystoscope must be protected against damage from impact. Never apply excessive force such as twisting or severely bending the shaft of the flexible cystoscope. Objective Lens and Eyepiece: Check the objective lens (distal tip) and eyepiece to assure that they are free of fingerprints, smudges or dust. If necessary, gently clean with a cotton tip applicator and 70% isopropyl alcohol. Deflection Lever: Slowly manipulate the deflection lever to see that it functions smoothly. Rapid manipulation of the deflection lever will shorten the life of the deflection cables. Working/Irrigation Channel Inlet: Check that the working channel/irrigation channel inlet is clean. With the flexible cystoscope in a straight, nondeflected position, check the working channel by slowly inserting an appropriate size guide wire through the working channel inlet. There should be minimal resistance. If significant resistance is encountered, DO NOT ATTEMPT TO INTRODUCE THE WIRE FURTHER. The channel may be damaged, and the flexible cystoscope should not be used. Warning: Do not use the flexible cystoscope, its accessories, or ancillary instruments that show visible signs of damage or that are difficult to use. Any malfunction of an accessory or instrument during a procedure could result in injury to the patient and damage to the flexible cystoscope.
