Biopsy valve 6b
The biopsy valve is attached to the working channel port allowing for insertion of endotherapy
instruments or attachment of syringes.
The cap of the biopsy valve can be detached to ease insertion of an endotherapy instrument
or accessory into the instrument channel port.
If not using an endotherapy instrument or accessory, always attach the cap to the biopsy
valve to avoid leakage and spraying of fluids from the open biopsy valve or reduction of
suction capability.
Tube connection 6c
The tube connection can be used to mount ETT with an ISO connector during intubation.
Insertion of the endoscope 7a
Lubricate the insertion cord with a water based medical grade lubricant when the endoscope
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 active endotherapy instrument (e.g. laser equipment, electrosurgical
equipment) in the working channel before the instrument distal end can be seen in the image.
