Insertion of wire guided type endo-therapy accessories
1.
Move the elevator control lever all the way in the "
it stops while only the guidewire is extended from the endoscope's distal
end.
2.
Hold the elevator control lever stationary that it can no longer move forward
in the "
U" direction. Then insert a wire guided type endo-therapy
accessory slowly from the proximal end of the guidewire while observing the
endoscopic image and X-ray images.
3.
When the tip of the wire guided type endo-therapy accessory comes in
contact with the forceps elevator, move the elevator control lever in the
opposite direction of the "
observing the endoscopic images.
4.
While observing endoscopic images and X-ray images, an operator and
their assistant should work together to insert the endo-therapy accessory
carefully without moving the guidewire from the desired position.
•
If the intestines contain a flammable gas, replace it with air or
a non-flammable gas such as CO
frequency cauterization treatment. Otherwise, fire or
explosion could result.
•
Not all parts of the endoscope are electrically insulated.
When applying high frequency current, there is a danger of
unintentional diathermy burns. Always wear electrically
insulating chemical-resistant gloves.
•
Never emit high frequency current before confirming that the
distal end of the high frequency endo-therapy accessory is in
the endoscopic field of view. Also confirm that the electrode
section and the mucous membrane in the vicinity of the target
area are at an enough distance from the distal end of the
endoscope. If the high frequency current is emitted while the
distal end of the endo-therapy accessory is not visible or too
close to the distal end of the endoscope, patient injury,
bleeding and/or perforation as well as equipment damage
can result.
