EVIS EXERA TJF TYPE 160VR OPERATION MANUAL
When the assistant function of the guidewire fixation does not work effectively,
using a guidewire with a length of less than 4.5 m may make it difficult to
exchange the wire guided type endo-therapy accessories. Prepare the guidewire
with a length of 4.5 m or more.
Using a guidewire with a length of 4.5 m or more, wire guided
type endo-therapy accessories can be exchanged without
using the assistant function of the guidewire fixation.
 Withdrawal of wire guided type endo-therapy accessories
1.
Insert the guidewire to the proximal end of the guidewire-type endo-therapy
accessory and advance the guidewire until it reaches the desired position
while observing the endoscopic image and X-ray images.
2.
When the forceps elevator is lowered, an operator and an assistant work
together to pull the end of the endo-therapy accessory into the endoscope
while observing the endoscopic image and X-ray images.
3.
When only the guidewire is extended from the endoscope’s distal end,
slowly move the elevator control lever all the way in “
U” direction until it
stops.
4.
The guidewire is fixed in the guidewire-locking groove on the forceps
elevator at the endoscope’s distal end (see Figure 4.4).

The stiff part of the guidewire is fixed at the guidewire-locking
groove more effectively.
