Use of the aScope 4 Cysto
The numbers in gray circles below refer to illustrations on page 2.
Inspection and preparation of the aScope 4 Cysto
Visual inspection of the aScope 4 Cysto 1
- Check that the pouch seal is intact before opening and discard the aScope 4 Cysto if the pouch seal has been damaged. 1a .
- Make sure to remove the protection pipe from the insertion cord 1b.
- Check that there are no impurities or damage on the aScope 4 Cysto such as rough surfaces, sharp edges or protrusions which may harm the patient 1c .
Refer to the Ambu displaying units Instructions for use for preparing and turning on the Ambu displaying units 2
Inspection of the image
- Connect the aScope 4 Cysto to the Ambu displaying unit by plugging the connector on the aScope 4 Cysto cable with blue arrow into the corresponding blue female connector on the Ambu displaying unit. Carefully align the arrows on the connector on the aScope 4 Cysto cable with the port on the Ambu displaying unit to prevent damage to the connectors 3 .
- Verify that a correctly oriented live video image appears on the Ambu displaying unit by pointing the distal end of the aScope 4 Cysto towards an object, e.g. the palm of your hand 4 .
- Adjust the image preferences on the Ambu displaying unit if necessary (please refer to the Ambu displaying unit Instructions for use).
- If the object cannot be seen clearly, wipe the distal end of the aScope 4 Cysto using a sterile cloth.
Preparation of the aScope 4 Cysto
- Carefully slide the control lever forwards and backwards to bend the bending section as much as possible. Then slide the control lever slowly to its neutral position. Confirm that the bending section functions smoothly and correctly and returns to a neutral position 5a .
- Test fluid instillation by connecting an infusion set or syringe with sterile water or saline solution with Luer connection directly to the working channel entry or via a stopcock.
Ensure that there are no leaks, and that water is emitted from the distal end 5b.
Operating the aScope 4 Cysto
If any malfunction should occur during the cystoscopic procedure, stop the
procedure immediately, put the distal end of the aScope 4 Cysto in its neutral
and non-angled position and slowly withdraw the cystoscope.
Holding the aScope 4 Cysto and manipulating the distal end
The handle of the aScope 4 Cysto can be held in either hand. The hand that is
not holding the cystoscope can be used to advance the insertion cord into the
patient’s lower urinary tract.
Use the thumb to move the bending lever. The bending lever is used to flex and
extend the distal end of the cystoscope in the vertical plane.
- Depending on the bending lever, the model is called standard (lever up = tip up) or reverse (lever up = tip down).
- The insertion cord should be held as straight as possible at all times in order to secure an optimal distal end bending angle.
Insertion of the aScope 4 Cysto 6
Lubricate the insertion cord with a soluble lubricant suitable for cystoscopy
before the aScope 4 Cysto is inserted into urethra. If the camera image of the
aScope 4 Cysto becomes unclear the distal end can be cleaned by gently rubbing
the distal end against the mucosal wall or withdraw the cystoscope and clean
the distal end.
Aspiration and instillation of fluids 7
Aspiration might be required during the procedure. Prepare a syringe for this.
When required,attach the syringe to the aScope 4 Cysto and apply an aspiration
force according to the wanted effect. For larger quantity of fluid, disconnect
the syringe from the cystoscope, empty the syringe, and then reattach it to
aspirate the remaining fluids.
Fluids e.g. sterile water or saline solution can be instilled through the
working channel entry at the bottom of the aScope 4 Cysto handle by connecting
a syringe or infusion set with Luer connection directly to the working channel
entry or via a stopcock. If using a sterile water or saline bag, make sure to
place it so that potential spillage will not affect other equipment.
Insertion of endoscopic instruments 8
Always make sure to select the correct size endoscopic instrument for the
aScope 4 Cysto
(see section 2.2.). Inspect the endoscopic instrument before using it. If
there is any irregularity in its operation or external appearance, replace it.
Insert the endoscopic instrument into the working channel entry and advance it
carefully through the working channel until it can be seen on the live image
on the Ambu displaying unit.
Withdrawal of the aScope 4 Cysto 9
When withdrawing the aScope 4 Cysto, make sure that the control lever is in
the neutral position. Slowly withdraw the cystoscope while watching the live
image on the displaying unit.
After use
Visual check 10
Check if there are any missing parts, evidence of damage, cuts, holes,
sagging, or other irregularities on the bending section, distal end, or
insertion cord of the aScope 4 Cysto. If yes, then take corrective action to
determine if any parts are missing and locate the missing part(s).
In case of corrective actions needed act according to local hospital
procedures. The elements of the insertion cord are visible in x-ray (radio
opaque).
Final steps
- Disconnect the aScope 4 Cysto from the Ambu displaying unit 11 .
- Dispose of the aScope 4 Cysto, which is a single-use device 12 . The aScope 4 Cysto is considered contaminated after use and must be disposed of in accordance with local guidelines for collection of infected medical devices with electronic components.
The product design and materials used are not designed for reuse and cannot withstand the reprocessing procedures used for reprocessing of endoscopes without the risk of degrading and being contaminated.
