EVIS EXERA TJF TYPE 160VR OPERATION MANUAL
• Do not withdraw the endoscope if the guidewire is stuck in
the guidewire-locking groove at the distal end. Patient injury,
bleeding and/or perforation can result. In this case, insert a
wire guided type endo-therapy accessory over the guidewire
from its proximal end, while observing the endoscopic
images to confirm that the guidewire does not penetrate
patient tissue. When the endo-therapy accessory passes
through the groove, it removes the guidewire from the
groove.
• The maximum angle of the forceps elevator is slightly
increased compared with conventional duodenoendoscopes,
due to the need to fix the guidewire at the distal end.
Therefore, endo-therapy accessories can be raised higher
than with other conventional duodenoendoscopes. Closely
observe the endoscopic image when using an endo-therapy
accessory with this endoscope, particularly while performing
papillotomy. Do not manipulate the elevator control lever
and/or endo-therapy accessory without closely viewing the
endoscopic image, as patient injury, bleeding and/or
perforation can result.
• The assistant function of the fixation works most effectively
with guidewires with a diameter of ø 0.89 mm (0.035 inch).
• The assistant function of the fixation may not work effectively
in the following conditions.
−
If the elevator control lever is not held stationary.
−
If the proximal ends of the wire guided type endo-therapy
accessory and the guidewire are not straight.
−
If the contrast media in the guidewire lumen of the
endo-therapy accessory is not washed with physiology
salt solution.
−
If the wire guided type endo-therapy accessory is kinked,
deformed or damaged.
−
If the combination of the guidewire and the wire guided
type endo-therapy is incorrect.
−
If an attempt is made to fix more than one guidewire
simultaneously.
−
If the position of the distal end of the endoscope and the
papilla is not appropriate for the assistant function of the
guidewire fixation (see NOTE on page 59).
