NOTE: If the tissue needs to be repositioned within the instrument before stapling, open the jaws by
squeezing the handle and closure trigger together slightly, push the release button, and slowly release
grasp of the closure trigger. The closure trigger will return to the fully open position and the jaws
will release the tissue but the retaining pin will remain extended. Tissue can now be repositioned.
NOTE: The muscle stapling C
partial closing if a used cartridge reload, no cartridge reload, or an incorrectly inserted cartridge
reload is in the instrument. In these cases, the device will close approximately one-third of the stroke
and stop, but will return to the full open position when the closure trigger is released. The used or
misloaded cartridge module should then be replaced with a new cartridge reload or, if no cartridge
was present, a cartridge should be loaded in the instrument. After following the above steps, any
device that does not close either partially or completely should not be used.
NOTE: After closing, pausing for 15 seconds prior to firing may result in better tissue compression
and better staple form.
With the handle and closure trigger grasped in the palm of the hand, place all fingers around the
6
firing trigger. Before firing, check to ensure the retaining pin is seated in the anvil.
Caution: Always ensure complete jaw closure prior to firing.
Caution: Before firing, verify that the intended tissue is in the closed jaws of the instrument. If
the pin is not properly positioned, staples may not form properly, which may result in leakage or
disruption of the staple line.
Caution: When positioning the stapler on the application site, ensure that no obstructions such as
clips, stents, guide wires, etc., are incorporated into the instrument jaws. Firing over an obstruction
may result in incomplete cutting action and/or improperly formed staples.
7 Completely fire the instrument by squeezing the firing trigger until it touches the closure trigger
(plastic to plastic), signifying that the instrument has fired the staples and knife blade, and the tissue
has been transected. (Illustration 5) The firing trigger automatically returns to the intermediate
position as soon as the hand releases it, leaving the closure trigger in the fully closed position. Make
sure that the release button is not pressed during firing as proper formation of staples and cut line
may be compromised.
Caution: Attempting to force the trigger to complete the closing stroke with too much tissue or
thickened tissue may result in poor staple line integrity with possible leakage or disruption. In
addition, instrument damage or failure may result.
Caution: The firing stroke must be completed. Do not partially fire the instrument. Incomplete firing
can result in malformed staples, incomplete cut line, bleeding, and leakage from the staple line and/or
difficulty removing the device.
8 After firing the instrument, open the jaws of the instrument by squeezing the closure trigger and
pushing the release button with the thumb. For controlled release, while holding the release button
down, open your hand to release the closure trigger. (Illustration 6) The cartridge drivers are exposed
as a spent cartridge indicator. If the instrument becomes locked onto tissue and will not open by
pressing the release button, the device can be opened by depressing the release button and pulling the
closure trigger simultaneously.
Caution: Examine the staple line for hemostasis and proper staple formation. If hemostasis is not
present, appropriate techniques should be used to achieve hemostasis.
9 Retract the retaining pin manually. Ensure that the staple line and the cut line are complete. Remove
the instrument. (Illustration 7)
Reloading the C Curved Cutter Stapler
ONTOUR
Using sterile technique, remove the reload from the package. To avoid damage, do not flip the reload
1
into the sterile field.
2 Depress the release button to ensure the instrument is in the open position. Ensure that the retaining
pin has been retracted.
3 Remove the used reload from the instrument. Grasp the top of the reload and lift upward, unsnapping
the reload from the jaws. (Illustration 8) Properly discard the used reload. Thoroughly clean the
instrument by vertically submerging completely the anvil and cartridge channel in a sterile solution
and swish vigorously. After swishing, visually inspect the anvil and cartridge channel and remove all
residual staples and/or foreign matter from instrument prior to reloading.
Caution: Failure to properly clean the instrument prior to reloading could damage the instrument;
compromise cut line and staple formation of subsequent firings.
