Aspiration (Suction)

Aspiration (Suction)
2-4
A vacuum pump in the console body provides up to 660 mm (26 in.) mercury
maximum vacuum at sea level. Adjustment buttons (green up/down arrows on
black buttons at the bottom of the aspiration display column on the control panel)
allow you to increase or decrease the suction from 10 to 100% in 10% increments.
The suction, which produces an air stream moving toward the vacuum pump,
pulls irrigation fluid, fragmented tissue, and other materials through the distal end
of the surgical tip. From the tip, the aspirated materials pass through the manifold
suction tubing into the suction canister. From the suction canister, the air stream
continues to flow through a contamination guard that filters any remaining
particulate matter or moisture, preventing them from entering the vacuum pump.
A suction pinch valve on the front of the console opens when the system is on and
closes to stop suction in the following cases:
• When priming the irrigation system
• When pressing the Fast Flush pedal
• In Run Status, when you release the Vibration pedal. In this case, the pinch
valve closes for about one second, then re-opens.
• In Lap Mode, when you release the Vibration pedal. This suction stoppage
prevents depletion of the pneumoperitoneum.
Caution
To avoid injury to surgical personnel, keep fingers away from the suction pinch valve.
When the System Power Switch is off, the suction pump remains off and the
suction pinch valve remains closed. A button on the front of the suction pinch
valve allows you to open the valve manually.
