is inserted into the patient. If the endoscopic image becomes unclear, the distal tip can be
cleaned by gently rubbing the distal tip against the mucosal wall or remove the endoscope
and clean the tip. When inserting the endoscope orally, it is recommended to use a
mouthpiece to protect the patient and the endoscope from being damaged.
Instillation of fluids 7b
Fluids can be instilled through the working channel by attaching a syringe to the biopsy valve.
When using a Luer Lock syringe, use the included introducer. Insert the syringe tip or the
introducer completely into the biopsy valve (with or without the valve's cap attached) and
press the plunger to instill fluid. Make sure you do not apply suction during this process, as this
will direct the instilled fluids into the suction collection system. To ensure that all fluid has left
the channel, flush the channel with 2 ml of air.
Aspiration 7c
When a suction system is connected to the suction connector, suction can be applied by
pressing the suction button with the index finger. If the introducer and/or an endoscopic
accessory is placed inside the working channel, note that the suction capability will be
reduced. For optimal suction capability it is recommended to remove the introducer or
syringe entirely during suction.
Insertion of endotherapy instruments or accessories 7d
Always make sure to select the correct size endotherapy instrument for the endoscope
(see section 2.2). Maximum compatible instrument size is indicated at the working channel port.
Inspect the endotherapy instrument before using it. If there is any irregularity in its operation or
external appearance, replace it. Insert the instrument into the biopsy valve and advance it
carefully through the working channel until it can be seen on the endoscopic image.
For insertion, hold the endotherapy instrument close to the opening of the biopsy valve and
insert it straight into the opening using gentle short strokes to avoid the endotherapy
instrument to bend or break. The enclosed introducer can be used to ease insertion of very
soft instruments such as soft catheters and protected specimen brushes if necessary. Use of
excessive force during insertion may damage the endotherapy instrument. When the bending
section of the endoscope angulates significantly and insertion of the endotherapy instrument
becomes difficult, straighten the bending section as much as possible.
Do not open the tip of the endotherapy instrument or extend the tip of the endotherapy
instrument from its sheath while the instrument is in the working channel, as this may damage
both the endotherapy instrument and the endoscope.
Insertion of active endotherapy instruments 7d
Use of active endotherapy instruments should always be operated according to the respective
manufacturer's instructions for use. Users shall always be familiar with safety precautions and
guidelines on the proper use of active endotherapy instruments, including use of adequate
personal protective equipment.
Do not activate an endotherapy instrument in the working channel before the instrument
distal end can be seen in the image.
It should be recognized that the use of active endotherapy instruments may interfere with
the normal endoscopic image and this interference is not indicative of a malfunction of
the endoscopic system. A variety of factors can affect the quality of the endoscopic image
during use of active endotherapy instruments. Factors such as intensity, high power setting,
close distance of the instrument probe to the endoscope tip and excessive tissue burning
can each adversely influence image quality.
Withdrawal of the endoscope 8
When withdrawing the endoscope, make sure that the control lever is in the neutral position.
Slowly withdraw the endoscope while watching the live endoscopic image.
