3. Either manually advance the retaining pin using the actuator button on top of the handle to capture the tissue

within the jaw opening (A), or automatically advance the retaining pin by partially squeezing the closure

trigger (B). In the intermediate position, the retaining pin is fully seated in the anvil capturing the tissue, and the

jaws are partially open, allowing for desired placement of tissue. Note that there is an audible click halfway

through the closure stroke indicating that the device is in the intermediate position.

Device preparation and placement

1. Remove the staple retainer from the instrument

by pushing on the pad labeled “Push to Remove.”

2. Position tissue to be cut and stapled between the anvil and the cartridge. If the tissue doesn’t it comfortably

within the jaws, you should consider two irings.

Device is reloadable to complete a single transection with multiple irings when needed. Any tissue covering

the hole in the anvil will be pierced by the retaining pin. The knife extends to the retaining pin and the staple

line extends beyond the pin supporting multiple irings.

Caution: To prevent premature iring, do not grasp the iring trigger.

4. Squeeze the closure trigger until latched, listening

for an audible click. After closing, holding the jaws

in place for 15 seconds prior to iring may result in

better tissue compression and staple formation.

To reposition tissue, open the jaws by squeezing

the handle and closure trigger together slightly,

and push the release button.

5. Completely ire the instrument by squeezing the

iring trigger until it touches the closure trigger

(plastic to plastic).

6. For a controlled opening, simultaneously squeeze

the closure trigger and push the release button

with the thumb.

7. Retract the retaining pin manually. Pull back retaining pin actuator to ensure that the retaining pin

has been fully retracted.

8. To remove the reload, grasp the top and follow the

curvature of the device. Be sure to grab the body

of the cartridge, not the black sleeve of the device.

9. 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.

Reloading the device

CAUTION: To prevent bunching, stretching or overloading of tissue in the jaws of the device, multiple irings may be used to complete a single transection. If the

closure trigger is diicult to lock, reposition the instrument and take a smaller amount of tissue. Attempting to force the trigger to complete the closing stroke may

result in poor staple formation, and this may result in leakage, lack of hemostasis or disruption of the staple line. In addition, instrument damage or failure may result.

Reloading the device (continued)

10. Insert the new reload by using the tracks on each

side as guides to align reload with jaws of the

instrument. Following the curvature of the device,

insert the new reload into the metal housing and

snap into position.
