Check of the Remote Switches
All remote switches should be checked to work normally even if they are not expected to be
used. The endoscopic image may freeze or other irregularities may occur during examination
and may cause patient injury, bleeding, and/or perforation.
• Press every remote switch and confirm that the specified functions work as expected.
Check of the endoscope's suction, rinsing and insufflation functionality
• Check that the suction and rinsing/insufflation valve work as expected by pressing both
the suction and rinsing/insufflation valve. Cover the opening of the rinsing / insufflation
valve and confirm that the corresponding function works properly.
4.4. Operating the aScope™ Duodeno
Insertion of the Endoscope 9
• Insert a suitable mouthpiece and place it between the patient's teeth or gums.
• Make sure the elevator is not raised before you insert the endoscope.
• If necessary, apply a medical-grade lubricant to the insertion section.
• Insert the distal end of the endoscope through the opening of the mouthpiece, then
from the mouth to the pharynx while viewing the endoscopic image. Do not insert the
insertion section into the mouth beyond the insertion section limit mark.
Holding and Manipulation of the endoscope
• The control section of the endoscope is designed to be held in the left hand.
• The insufflation/rinsing and suction valves can be operated using the left index finger.
• The UP/DOWN angulation control wheel and the elevator control lever can be operated
using the left thumb of the left hand.
• The right hand is free to manipulate the insertion section and the RIGHT/LEFT angulation
control wheel.
Angulation of the Distal End
• Operate the angulation control wheels as necessary to guide the distal end for insertion
and observation.
• The endoscope's angulation locking levers are used to hold the angulated distal end
in position.
Insufflation/Rinsing
• Cover the insufflation/rinsing valve's hole to feed air from the insufflation/rinsing valves
to the distal end. Press the insufflation/rinsing valve to feed water onto the objective lens.
Instillation of Fluids
• Fluids can be instilled through the working channel by inserting a fluid-filled syringe into
the working channel port of the aScope™ Duodeno. Insert the syringe completely into
the working channel port 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 fluids have left the channel,
flush the channel with ca. 5 seconds of air.
Suction
• Press the suction valve to aspirate excess fluids or other debris obscuring
the endoscopic image.
• For optimal suction capability, it is recommended to remove accessories entirely
prior to suction.
Insertion of Endoscopic Accessories
Always make sure to select the correct size endoscopic accessory for the aScope™ Duodeno.
