RECEIVING INSPECTION

The system was inspected mechanically and electrically prior to shipment. If the shipping container appears damaged, ask that the carrier’s agent be present when the system is unpacked. The system should be inspected for external damage (i.e. scratches, dents, or broken parts). If damage is discovered or if the system fails any of the functional tests notify the carrier and an Alcon Surgical representative. Retain the shipping container and packing material for the carrier’s inspection. As necessary, file a claim with the carrier or, if insured separately, with the insurance company.

CAUTERY, DIATHERMY, COAGULATION

In the past, some of Alcon Surgical’s products have referred to the feature “Cautery.” The STTL uses the word “Coagulation” in place of Cautery, based on the following definitions:
• Cautery - cutting and burning method associated with two hot wires passing a current between them; cutting away skin; halting bleeding.
• Diathermy - introducing an electric field into a body part to produce heat.
• Coagulation - an isolated bipolar current supplied to conductors (e.g. forceps). Current passes between these electrodes, halting bleeding. (Abbreviated “Coag” in some of the text of this operator’s manual.)

ELECTRONIC SYSTEM

The STTL is a multi microprocessor-controlled system with associated memory and input/output (I/O) circuitry. The system communicates via the Front Panel. An automatic self-test is initiated each time the system is turned on. This test performs a variety of checks including the following:
• Tests the Central Processing Unit (CPU)
• Tests the RAM and ROM memory, and the I/O circuits
• Initializes the system
• Defaults to: IRR: Footswitch mode (V3.01 and below) Advantec: Visco mode (V3.12 and above)
When the system successfully completes the self-test, it automatically goes into the default mode. If the system fails the self-test, an error message is displayed. Voice confirmation verifies all mode selections.

SYSTEM DESIGN

Front Panel
The front control panel (see Figure 2-1) has a flat, non-glare surface located on the front of the main chassis. It contains a graphics display, a touch screen, up and down arrows, mode buttons, bottle height, U/S time displays, and a Test button.
The buttons are located both on the sides and on the bottom of the screen. There are two basic push-type buttons on the front panel: (1) Those that control up and down arrows: press and hold until the adjustment is complete and (2) Those that are momentary buttons: a single push-and-release activates the function. The momentary buttons and the up/down arrows emit an audible signal to indicate key activation.
1.
Standby Power Switch - This is a two-position, rocker-type switch used to turn secondary power (part of equipment) ON and OFF. It is located to the right of the speaker on the front of the machine. This
switch is used to turn the system ON/OFF between surgeries.

REMOTE CONTROL

The Series 20000™* remote control (see Figure 1-9) is wireless and can, therefore, be used in one of three ways: It can be laid into the articulated arm and tray assembly and operated through the sterile drape supplied in the disposable pak. This offers the Scrub Nurse or assistant access to the controls from the sterile field. A sterile, sealed pouch (available in the remote control aseptic transfer packaging) can also be utilized to maintain the sterile field if the remote is used in a hand-held manner. The circulator could also operate the remote in a non­sterile manner. Programmability and custom user
setup features are functions which are not accessible from the remote control.
The error message, “RMT BAT LO” is displayed in the text window on the front panel when the remote batteries are low. (The battery compartment on the back holds four AA batteries; to replace batteries, loosen the captive screw on the compartment door with a standard screwdriver.)
The controls on the remote control have been arranged to approximate the respective controls on the console’s front panel. The Test button has a raised area around it; this differentiates it from the other buttons in order to ensure that the test function is not accidentally actuated. All controls are backlit by heat actuation; i.e., illumination in low ambient light is activated when the sensor detects heat from the hand.
On systems with software V3.01 and below: There are three inactive keys for future expansion: one marked SCROLL, one marked ENTER, and one undesignated.
On systems with software V3.12 and above: The Forward and Reverse buttons functionality can be customized using the Custom Footswitch screen.
The remote control can be configured to operate on one of four channels (A, B, C, or D). This feature allows four remote controls to independently control four systems operating in the same room or area. Remote controls are factory preset to channel A. To change channels, access the switch located in the battery compartment (see Figure 1-10). For proper remote operation, the system must be set to the same channel as the remote. Once the correct channel is selected on the system, no other steps are needed to save it into memory.
To ensure proper operation when two or more remote controls are being used in the same room or area, adjust each system including remote control to separate channels.
NOTE: Label the remote controls and the units, if necessary.
CAUTION
Do not sterilize the remote control as it will damage the unit.

MODES AND FUNCTIONS

The STTL has seven basic operational modes or functions, some with submodes (see Figure 1.11). Each allows for the appropriate adjustment of the power, aspiration, and vacuum settings. These settings can be put into one of 96 (V3.01 and below) or 384 (V3.12 and above) memory programs and, consequently, be available for future use without having to re-program the instrument.
The operating modes are selectable from the unit’s front panel controls or from the remote control unit. The functions within an operating mode are controlled by the operating position of the footpedal. Mode changes will result in voice confirmation. (The user has the ability to turn this feature off via the Custom menus.) An audible beeper-tone is generated to indicate a change in the operating mode and to alert the operator of certain conditions such as an occluded line. Additionally, a varied pitch tone is generated to audibly indicate vacuum levels; the pitch increases as the vacuum level increases. The volume of the audible variable-pitch tone is adjustable via the Custom menus.
the front panel settings are controlling the system the word Panel is illuminated; if the footswitch is controlling the system the word Surgeon, Srg Asp, or Srg Vac is illuminated.
Coagulation during test states, except for tuning, is available in Panel control modality.
When a mode button is pressed, the symbol becomes animated and the selected sub mode is highlighted. The titles of the selected mode and submode are displayed in the text window.
The following sections provide an overview of each mode and, where applicable, the differences between operating in the various control modes.
Irrigation (Irr) Mode
Irrigation operates on a gravity-feed principle from the IV bottle, through the cassette irrigation valve to handpiece. The irrigation valve is normally closed when cassette is inserted. Bottle height is measured from the patient's eye to mid-drip chamber.
The operating mode/function is displayed in the mode display window. The primary modes of operation are Irrigation (IRR), Advantec (V3.12 and above) HydroSonics™* (V3.01 and below), Ultrasonics (U/S), Irrigation/Aspiration (I/A), Vitrectomy (Vit), and Coagulation (Coag). Preset (default) operating parameters for the selected mode are programmed into the system, or new operating parameters can be set by using the front panel or remote.
Depending on the operating mode, the system can be set up to automatically operate at the preset limits displayed on the front panel displays, or to provide linear control of one of the operating parameters from the footswitch. The controlling factor is determined by the control mode switches (Panel/Surgeon/Srg Asp/Srg Vac). In general, if

In the Irrigation mode, Panel and Surgeon functions are not available; therefore, they are not illuminated. Irrigation mode has three sub modes:
• Irrigation: Footswitch - entered when system is turned on (default) or by pressing the IRR mode button when operating in another mode. The mode display window reads Irrigation: FootSwitch. Irrigation is provided in footpedal positions 1, 2, and 3.
• Irrigation: Free Flow - entered by pressing Free Flow icon or irrigation button. The mode display window reads Irrigation: FreeFlow. Free flow irrigation continues until the IRR button is pressed twice to change to Irrigation: Footswitch or until another mode is selected (except when continuous irrigation option is turned on).
• Continuous Irrigation - Continuous Irrigation is available as a floating sub mode for U/S, I/A, and Vit modes to allow for continuous irrigation of the eye during surgery. It maintains irrigation of the anterior chamber independent of footpedal position (i.e., even in position 0). It is described as a floating mode as it can start from Irrigation and go to any allowable mode. Exiting from U/S, I/A, or Vit modes shuts Continuous Irrigation off allowing leak-free exchange of irrigation and aspiration lines to handpieces.
2. When enabled, toggling the footswitch's right horizontal switch in footpedal position 0 opens and closes the irrigation valve to provide continuous irrigation in a similar manner.
Continuous Irrigation is not available in Test, HydroSonics™*, or Coagulation modes.
Providing Access to the Continuous Irrigation Footswitch Feature The Continuous Irrigation Footswitch feature is normally disabled. To access this feature, the user must enter the Custom menu and select the Footswitch menu. The Enable and Disable switches for Continuous Irrigation will be found on the left side of the screen. Continuous Irrigation can be accessed in any of the Custom detent modes. For convenience, this feature can be programmed into a doctor’s memory. This provides only the ability for Continuous Irrigation Footswitch feature to be enabled.
Actual Use of Continuous Irrigation Continuous irrigation cannot turn on automatically even though the Custom Continuous Irrigation Footswitch switch is enabled. It must be invoked by either depressing the Continuous Irrigation sub mode from the front panel or by the footswitch's right horizontal switch.
Continuous Irrigation is activated by one of two methods for U/S, I/A, and Vit modes:
1. Transferring from Continuous Irrigation to another mode. If the system is in Irrigation: Continuous, irrigation will be carried over to the next mode selected unless the new mode does not support it.

The footswitch can toggle the irrigation switch on and off in the Custom mode, though. Changing memories will not affect status of Continuous Irrigation. If a particular memory setting is not footswitch programmed, switching the Continuous Irrigation on and off can only be done via the front panel.
An audio beep confirmation is heard each time the Continuous Irrigation valve is opened, and two beeps when the valve is closed. The front panel also displays activation of Continuous Irrigation above the Irrigation mode symbol.
When exiting from U/S, I/A, or Vit modes the system automatically shuts off Continuous Irrigation regardless of how it was turned on. This allows leak-free exchange of the irrigation and aspiration lines to the handpieces. It can also be shut off by the footswitch's right horizontal switch. Before switching handpieces, it is advised to tap the right horizontal switch or change modes after exiting the eye to prevent excess BSS® sterile irrigating solution from flowing out of the handpieces.

HydroSonics™* (Hydro) Mode (software V3.01 and below)
Because this mode has only one function, pressing the Hydro button puts the unit into the HydroSonics™* mode immediately. The mode display window reads U/S: Hydro. The HydroSonics™* mode allows use of the auto HydroSonics™* handpiece, which allows the surgeon to perform hydrodissection and soften the cataract prior to phaco-emulsification. No aspiration is provided in the HydroSonics™* mode.
Injection Rate and U/S Power are the primary parameters displayed in the HydroSonics™* mode. Pulse Rate is the secondary parameter. It is displayed in the window located in the lower right hand portion of the front panel and is controlled with the arrows to the right of this window. Following are the allowable injection rates (pulses/min.) in the HydroSonics™* mode: 60, 70, 80, 90 and 100.
NOTE: When in HydroSonics™* mode the left Reflux pedal provides pulsed injection only, with no U/S.
• If
Panel Control is selected, pulsed fixed ultrasonic power is delivered in footpedal position 2 at the preset or operator set power level maximum limit. The ultrasonic power maximum limit is initialized to 80% at power up. In footpedal position 3 fixed ultrasonic power and pulsed injection are provided. The injection rate is initialized to 60 pulses/min. at power up.
AdvanTec Mode (software V3.12 and above)
AdvanTec Mode supports the NeoSonix™*, the 375/40, and the Mackool** 375/40 U/S handpieces. When the AdvanTec function is operational, irrigation, aspiration, and ultrasonics are provided by the handpiece. In addition to these, the NeoSonix™* handpiece provides mechanical oscillations. The user has the ability to adjust the aspiration rate, vacuum levels, U/S power and NeoSonix™* parameters, Amplitude and Threshold (if applicable) above or below the preset levels at any time during the surgical procedure via the respective adjustment buttons or the remote control. The
NeoSonix™* parameters become active when the NeoSonix™* handpiece is attached, otherwise they are

If the Lin Flow button is not highlighted, footpedal position 2 provides irrigation and fixed aspiration according to the flow rate selected. When Lin Flow button is highlighted, the console will announce "Linear Flow." When the button is pressed again (Lin Flow not highlighted), the console will announce "Fixed Flow." If Lin Flow is highlighted, footpedal position 2 provides irrigation and aspiration proportional to the displacement of footpedal throughout position 2. It starts at 0 cc/min at the top of the position 2 and reaches maximum value as set on the screen at the bottom of position 2.
Footpedal position 3 provides irrigation, fixed aspiration flow rate as set on the main screen or on the Custom/ Special Functions/Aspiration screen if defined and different from the flow rate set on the main screen.
If U/S Panel Control (including linear or fixed flow in footpedal position 2) is selected, ultrasound power will be constant throughout the footpedal position 3 and equal to the power setting as set on the screen. To increase or decrease power, the arrow buttons are activated. The default maximum U/S power level setting is 60% except for AdvanTec Visco submode where it is 0%.
If U/S Surgeon Control (including linear or fixed flow in footpedal position 2) is selected, the ultrasound power display indicates the maximum power available. To increase ultrasonic power the surgeon must further depress the footpedal into position 3. Power starts at 0% and increases until power reaches the displayed maximum setting. To change the maximum available power, activate the up or down arrow which will raise or lower the maximum power available. The default maximum U/S power level setting is 60%, except for AdvanTec Visco submode where it is 0%.
NeoSonix™* oscillations are activated when the ultrasound power reaches or exceeds the NeoSonix™* threshold displayed on the screen. At that point oscillations are activated according to the NeoSonix™* amplitude displayed on the screen. There is no proportional Surgeon control of the NeoSonix™* amplitude. In footpedal position 1-2 the amplitude maximum value is displayed. In footpedal position 3 the actual value of the amplitude is displayed, that is, 0% is displayed while the ultrasound power is less than the NeoSonix™* threshold, and the maximum amplitude value is displayed when the ultrasound power is equal to or exceeds the threshold.

AdvanTec Visco The AdvanTec Visco submode is automatically entered when system power is initially turned ON and the self test is successfully passed, or when the AdvanTec button is pressed, “AdvanTec: Visco” is displayed, and the NeoSonix™* or 375/40 U/S handpiece is activated.
This submode is designed to simplify creation of working space in the anterior chamber filled with a viscoelastic material prior to engaging ultrasound. Viscoelastic material can occlude the aspiration port and/or reduce wound leakage. Either of the events, and especially a combination of both, can lead to rapid and significant increase of temperature in the anterior chamber, especially at the incision site when ultrasound is activated. To minimize the possibility of thermal injury to eye tissues it is therefore recommended to partially aspirate viscoelastic material from the anterior chamber.
The AdvanTec Visco submode contains default values of 120 mm Hg vacuum limit, and 0% of ultrasound power and NeoSonix™* amplitude. If a user finds it helpful to add a small amount of ultrasound or NeoSonix™* action to facilitate partial removal of viscoelastic, the ultrasound and/or NeoSonix™* will be available pulsed at 8 pulses per second, 25% time on, 75% time off. Maximum ultrasound power is limited to 50% in this submode.
