Withdrawal of EndoTherapy accessories
1.
Close the tip of the EndoTherapy accessory and/or retract it into its sheath.
2.
While lowering the forceps elevator gradually, slowly withdraw the
EndoTherapy accessory.
Locking the guidewire
The TJF-Q180V is designed to lock the guidewire in place during wire-guided
type EndoTherapy accessory withdrawal or insertion, such as when a guidewire
has been placed through a cannulation device into the biliary or pancreatic duct
and this device must be removed from the endoscope and exchanged for a
different EndoTherapy accessory. When locking or replacing the guidewire,
follow the warnings below.
EVIS EXERA II TJF TYPE Q180V OPERATION MANUAL
• Patient debris might spray when EndoTherapy accessories
are withdrawn from the biopsy valve. To prevent this, hold a
piece of gauze around the accessory and the biopsy valve
during withdrawal.
• Do not withdraw the EndoTherapy accessory if the tip is open
or extended from its sheath; patient injury, bleeding,
perforation, and/or instrument damage may occur.
• Withdraw the EndoTherapy accessory slowly and straight out
of the biopsy valve. Otherwise, the valve's slit and/or hole
could be damaged. This can reduce the efficacy of the
endoscope's suction system and may leak or spray patient
debris or fluids, posing an infection control risk.
• If the EndoTherapy accessory cannot be withdrawn from the
endoscope, stop the procedure immediately and contact
Olympus without changing the position of the instrument.
• Do not use a guidewire when its outer surface is damaged.
This could allow leakage current to flow from the guidewire to
the endoscope and/or the patient, and it could cause burns to
the patient, operator, and/or assistant. Also, it could damage
the endoscope, equipment, and/or EndoTherapy accessory.
• Manipulate the elevator control lever and the insertion
section of the endoscope slowly while viewing the papilla
when locking the guidewire at the distal end of the
endoscope. Otherwise, patient injury, bleeding, and/or
perforation may result.
