Operating CUSA NXT During the Surgery
After setting up the system, it is ready to be used for surgery. Note the follow-
ing guidelines when using the CUSA NXT during surgery:
Increasing the power setting (orange) increases cell disruption at the
handpiece tip.
Increasing the irrigation setting (blue) increases the irrigation flow.
Increasing the aspiration setting (green) increases the suction at the
handpiece tip.
During the surgical procedures you may adjust these variables by adjusting
the appropriate scales on the touch screen.
1. Verify that the handpiece is fully primed.
2. Set the aspiration, irrigation, and power levels to the desired settings. If desired, use the
presets option to select the pre-defined settings (see page 17). Recommended settings
are:
80 % for power
3 ml/min for irrigation
80 % for aspiration
3. Hold the handpiece in the sterile field and verify the following:
The tip is not in contact with any object.
The aspiration and irrigation tubes are free from kinks or other obstructions.
4. Press the Power pedal on the Footswitch for at least 2 seconds to activate the handpiece.
Verify that a fine aerosol spray of irrigant appears at the tip showing that ultrasonic power
is present.
5. To operate the ultrasonic aspirator, press the Power pedal. Aspiration operates continu-
ously and irrigation is activated at the pre-set level when the pedal is pressed. Ultrasonic
power is controlled in a linear fashion - increasing as the Power pedal is pressed further
until, at full depression, it reaches the maximum level set on the power display on the front
panel.
6. If the surgeon only wishes to irrigate the operating site, press the Fast Flush Footswitch
pedal. Irrigant will flow from the end of the handpiece at a rate of 50ml/min.
7. If a problem occurs, see CUSA NXT troubleshooting guide, or the CUSA NXT Operator’s
Manual for troubleshooting guidelines.
8. If blockage occurs in the handpiece during operation, use the supplied sterilized nylon
stylet packaged with each tubing set to clear it. When using the stylet, pass it into the tita-
nium tip of the handpiece until the blockage is cleared. After clearing the blockage, im-
merse the tip into sterile water or saline.
9. If for any reason the Console is powered down for a period of less than 30 minutes and
then powered up, the Surgery Mode is immediately accessed, bypassing the normal prim-
ing procedure.
NOTE! During intervals of operative use, we recommend immersing the tip of the handpiece
momentarily into sterile water or saline. This will prevent blood and tissue debris from drying on
the inner surfaces of the handpiece and aspiration line and minimize the risk of a blockage in
the aspiration system.
