Instrument Preparation

Before starting any surgical procedure, it is crucial to prepare your instrument correctly.

Unpack the Device:

1. Open the graphic carton and remove the instruction manual along with the instrument, which is securely placed in its plastic packaging.

2. Follow the arrow on the dialysis paper to tear it off, then extract the stapler.

3. Remove the single-use loading unit in a similar manner.

Pre-Loading Checks:

1. Trigger: Ensure the trigger moves smoothly.

2. Stapler: Clear the stapler of any obstructions.

3. Rotating Knob: Confirm that the rotating knob is in the middle position.

4. Yellow Protective Cap: Do not remove this cap until the cartridge is loaded.

5. Cartridge Inspection: Verify that the cartridge’s yellow protective cap is correctly positioned and ensure the jaw remains open during installation.

Loading the Cartridge

Proper cartridge loading is essential for the device's functionality.

1. Insert the Cartridge:

Slide the cartridge from the bottom into the cartridge.

Align it with the alignment tab, and press firmly until an audible “click” confirms proper placement.

2. Remove the Protective Cap:

Once the cartridge is securely in place, remove the yellow protective cap.

Insertion of the Instrument

Correct insertion is critical for safe and effective surgical performance.

1. Activate the Trigger:

Pull the trigger to close the jaw, ensuring that it makes full contact with the handle.

2. Trocar Insertion:

Insert the stapler into the patient’s body via a suitable trocar.

Confirm that the double articulating joints clear the trocar completely.

3. Adjust the Angle:

To open the jaws, either press the release button or pull back the release knob.

Rotate the wrench to adjust the angle to a maximum of 60°. The instrument offers four preset positions: 15°, 30°, 45°, and 60° (with independent gear adjustments for each side).

Firing Process

The firing process secures the tissue and completes the stapling sequence.

1. Clamp the Tissue:

Ensure that the target tissue is clamped securely.

2. Engage the Trigger:

Press the trigger firmly, maintaining a tight grip on the tissue.

3. Timed Delay:

Wait for 15 seconds after clamping before proceeding.

4. Safety and Firing:

Pull the green safety.

Press the trigger repeatedly in controlled steps until the entire firing process is complete.

5. Completion Check:

Confirm the process is finished by observing the cutting indicator under the microscope or by monitoring the release button on the stapler.

Releasing the Instrument

After the firing process, safely release the instrument.

1. Open the Jaws:

Pull back the release button fully to open the jaw.

2. Reset Articulating Cartridge:

For articulating cartridges, turn the rotating wrench to return the cartridge to its original position.

3. Check for Bleeding:

Ensure there is no bleeding on the sutured tissue before proceeding.

Removal and Unloading

Final steps involve safely removing the instrument and unloading the used cartridge.

1. Extract the Stapler:

Close the jaw and carefully remove the stapler through the trocar.

2. Unload the Cartridge:

Push the distal end of the cartridge to detach it from the stapler.

Precautions and Final Checks

• Pre-Use Inspection: Always verify that the trigger and stapler mechanism are smooth and clear.

• Cartridge Installation: Ensure the yellow protective cap remains in place until the cartridge is loaded.

• Safety First: Follow each step meticulously to avoid any complications during surgery.
