4. Squeeze the Slider and Thumb Ring to prevent inadvertent opening of the biopsy cups when inserting the instrument into the
endoscope.
Note: Spring loaded handle is designed to minimize biopsy cups from opening during the exchange process. SEE FIG.1.
5. Advance the forceps into the endoscope biopsy channel using short strokes (1.0 to 1.5 inches) to avoid kinking the sheath.
Caution: Do not force the forceps through the endoscope. Forcing the device through the endoscope could cause damage to the
device or endoscope.
6. Maintain fluoroscopic imaging.
7. Advance the forceps out of the endoscope and advance the device to desired area within the lesion.
Note: Reduce the angulation of the endoscope or lower the forceps elevator in the endoscope if resistance is felt.
8. OPEN the cups by moving the Slider away from the Thumb Ring. SEE FIG.1.
9. ADVANCE the forceps with the cups OPEN to the desired tissue while maintaining fluoroscopic imaging.
10. CLOSE the cups by moving the Slider toward the Thumb Ring, and grasp the tissue. SEE FIG.1.
Caution: Use only enough pressure to bite the tissue. Over-exertion could cause forceps to become misaligned or to fail.
11. Maintain pressure on the Slider and Thumb Ring.
12. Grasp the biopsy forceps metal sheath.
13. Pull in a direction to remove the tissue sample from the lesion.
14. Remove the forceps from endoscope using slow continuous strokes to minimize the scatter of bodily fluids.
15. Remove the forceps from the guidewire.
16. Transfer specimen to a specimen jar and medium for preservation for pathology per institutional guidelines.
17. Rinse the forceps in sterile water while actuating handle until any excess tissue/specimen is removed.
18. If additional tissue sample is desired, visually inspect the device for damage and then repeat steps 1-15.
