CUSA NXT Touch Screen Monitor

The CUSA NXT Console provides a touch screen monitor for viewing and controlling the

power, irrigation and aspiration levels during an ultra-

sonic case.

The touch screen provides the following tools:

1. Status and alarm symbols

2. Ultrasonic control scales for power, irrigation and as-

piration

3. Information panel displaying the accumulated ultra-

sonic time and the current vacuum levels

4. Menu buttons for priming the handpiece, customizing

the user settings and viewing the online help.

Status and Alarm Symbols

The file symbols appear on the top of the touch screen providing status information on the

major ultrasonic components. During normal operation, all the symbols appear green. If an

error occurs with any of the major components, an alarm will sound and the respective sym-

bol will turn from green to flashing yellow.

Adjusting the Ultrasonic Control Scales

Use the power, irrigation, and aspiration scales to control the major ultrasonic

settings during a case.

Adjusting the power level

Use the power scale (orange) to specify the ultrasonic power output (tip ampli-

tude). The power settings range between 10% and 100%. Note that raising the

power setting will increase the vibration of the handpiece tip and thus increase

tissue fragmentation rate. To adjust the power by 5% increments, use the arrows to

the right of the scale. To adjust the power by 10% increments, press the segment

bars on the scale.

Adjusting the irrigation level

Use the irrigation scale (blue) to specify the rate of irrigation that will be delivered

to the handpiece. The irrigation rate ranges between 2 and 20 ml/minute. To adjust

this rate by 1 ml/minute increments, use the arrows to the right of the scale. To ad-

just the rate by 2 ml/minute increments, press the desired segment on the scale.

Adjusting the aspiration level

Use the aspiration scale (green) to specify the aspiration rate of the total available

suction of the source of vacuum employed. To adjust the rate by 5% increments,

press the arrows to the right of the scale. To adjust the rate by 10% increments,

press the segment bars on the scale. Note that typical aspiration rates are be-

tween 30% and 100%.

Verifying General Ultrasonic Information

Use the information panel to determine the general status of the current operating modes and

equipment selection. This panel provides the following information:

 The Timer displays the total accumulated ultrasonic time since the

machine was powered on. This value will reset to 00:00 if the machine

is turned off for more than 30 minutes.

 The Vacuum symbol displays the current vacuum level from the

aspiration source. This level is measured in mm hg units.

Displaying Menus for Prime Mode, Customized Settings, and Online Help

Use the menu buttons to access features for priming the handpiece, customizing user settings,

and displaying online help. Note the following buttons:

 Prime: Displays the prime panel for priming the handpiece for surgery

 Settings: Displays options for saving customized settings and specify-

ing different languages.

 Help: Displays the online help system for accessing information on

performing common tasks.
