STEP 3: FIRE THE INSTRUMENT
Two firing sequence methods are available once the Achieve
biopsy device is charged.
A = Automatic mode
D = Delay mode (Stylet Only)
1. Delay Mode – Depression of the D button releases the
inner stylet into the sample area. The operator uses this
delay firing method to verify the position of the sample
notch in the target area prior to depressing the A button,
which activates the cutting cannula, capturing the tissue
sample.
NOTE: If desired, a slight bias may be imparted to the
stylet prior to firing by forcing the stylet notch against the
lesion. Take care to avoid bending the stylet notch.
2. Automatic Mode – The operator can choose the fully
sequential mode, omitting the delay feature, simply by
depressing the A button first. This releases the stylet and
cutting cannula in sequence, capturing the tissue sample.
STEP 4: BIOPSY SPECIMEN
To retrieve the tissue sample, remove the device from the
patient, hold it with the A and D buttons facing up, and pull
back and release the charging handle once. This action will
retract the outer cutting cannula, exposing the stylet notch
with the tissue sample. See Figure 3.
STEP 5: OBTAINING MULTIPLE SAMPLES
After the tissue sample is removed, additional samples from
the same patient may be obtained. To obtain additional
samples, pull the charging handle a second time, which will
retract the stylet within the cutting cannula, placing the
Achieve device in a fully charged position. See Figure 4.
MANUAL STYLET INSERTION MODE
Reasons for performing a biopsy in this manner include:
a desire to push through a dense lesion slowly with the
combined strength of the stylet and cannula, and a desire
to visualize the placement of the needle within the lesion
prior to firing.
STEP 1: POSITION THE NEEDLE
Position the needle such that the tip of the needle extends
through the target area.
STEP 2: REVEAL THE STYLET NOTCH
While holding the handle steady, pull back on the charging
handle one time to charge the cannula and reveal the stylet
notch. Take care to maintain the position of the stylet tip
while charging the cannula.
STEP 3: FIRE CANNULA
NOTE: If desired, a slight bias may be imparted to the stylet
prior to firing by forcing the stylet notch against the lesion.
Take care to avoid bending the stylet notch. Press the A
button to fire the cannula through the target site.
STEP 4: BIOPSY SPECIMEN
To retrieve the tissue sample, remove the device from the
patient, hold it with the A and D buttons facing up, and pull
back and release the charging handle once. This action will
retract the outer cutting cannula, exposing the stylet notch
with the tissue sample.
STEP 5: OBTAINING MULTIPLE SAMPLES
After the tissue sample is removed, additional samples from
the same patient may be obtained. To obtain additional
samples, press the A button while holding the outer cutting
cannula adjacent to the handle. This action will place the
Achieve device in the uncharged position, and prevent
damage to the stylet or cannula tips.
