BF TYPE 160 Series OPERATION MANUAL
• Do not use the channel cleaning brush for cytologic tissue
sampling or other diagnostic or therapeutic purposes. Patient
injury, cross-contamination and/or equipment damage may
occur.
• When using a biopsy forceps with a needle, confirm that the
needle is not bent excessively. A bent needle could protrude
from the closed cups of the biopsy forceps. Using such a
biopsy forceps could damage the instrument channel and/or
cause patient injury.
• When using an injector, be sure not to extend or retract the
needle from the catheter of the injector until the injector is
extended from the distal end of the endoscope. The needle
could damage the instrument channel if extended inside the
channel, or if the injector is inserted or withdrawn while the
needle is extended.
Insertion of endo-therapy accessories into the endoscope
• The force required to insert an endo-therapy accessory is
reduced if the biopsy valve’s cap is detached from the main
body. However, a detached cap can reduce the efficacy of
the endoscope’s suction system and may cause patient
debris to leak or spray from the endoscope. Whenever
endo-therapy accessories are not used, attach the biopsy
valve’s cap to the main body.
• Do not insert endo-therapy accessories forcibly or abruptly.
Otherwise, the endo-therapy accessory may extend from the
distal end of the endoscope abruptly, which could cause
patient injury, bleeding and/or perforation.
1. Select endo-therapy accessories compatible with the instrument from the
“System chart” in the Appendix. Also refer to the instruction manuals of the
endo-therapy accessories.
2. Hold the UP/DOWN angulation control lever stationary.
3. Confirm that the tip of the endo-therapy accessory is closed or retracted into
its sheath and insert the endo-therapy accessory slowly and straight into the
slit of the biopsy valve.
