User Manual part 2

8065751025 2.1Constellation® Vision System INTRODUCTIONThe Constellation® Vision System is a multi microprocessor-controlled ophthalmic surgical instrument with associated memory and input/output (I/O) circuitry. The system communicates with the user via its Front Panel display, with voice confirmations, and with tones. An automatic self-test is initiated each time the system power is turned on. This test performs a variety of functions including the following: • Tests the Central Processing Unit (CPU) • Tests the RAM and ROM memory, and the I/O circuits • Initializes the system When the system successfully completes the self-test, it automatically goes into the Setup mode. If the system fails the self-test, an error message is displayed. This section of the manual is broken into two major parts. The first part describes the console and its accessories. All the parts of the system are described, including the front panel, rear panel, IV pole, connectors, fluidic interface, footswitch, remote control, and VideOverlay system. The second part of this section describes the operator interface. This is where the display screens for system setup, surgery, programming, and dialogs are shown.FRONT PANELFluidics ModuleThe fluidics module is located in the center of the front panel. The module allows fast and easy insertion of the cassette that contains all the fluidics connections required for surgery.Front Display Panel and Touch ScreenThe 17-inch front display panel tilts and extends forward to allow easy positioning during setup and surgery. The front display is the user's main source of system control, allowing fingertip command of system functions throught the enhanced graphical user interface. A data card slot is located just beneath the LCD display. A data card (SD Memory Card) can be inserted into this slot when the user wants to back up or restore system settings. SECTION TWODESCRIPTION
2.2 8065751025Constellation® Vision SystemPneumatic and Electrical ConnectorsThe Constellation® Vision System console contains two vertical columns of connectors, located on the left side of the cassette, for surgical probes and handpieces. The right column is for pneumatic probes, and the left column is for electrical handpieces. LED Rings - The rings surrounding each front panel connector automatically illuminate in a particular color to guide the user in making the proper connection to the system as follows:Blue - When a surgical tool selection is made in a Setup screen, the LED ring around the related connector illuminates in a blue colorGreen - When the surgical tool is connected correctly, the system changes the LED ring to green. Once lit, the LED ring remains on until another tool/port is selected or the system transitions to the surgery screen(s).Amber - If the surgical tool is connected incorrectly, the LED ring illuminates in an amber color until the condition is corrected.WARNING!Connect only Alcon supplied consumables to console/cassette connectors. Do not connect consumables to patient intravenous connections.Footswitch Storage Hook This footswitch storage hook is located at the bottom of the front panel. When the footswitch is not in use or the system is being moved, use this hook to store and protect the footswitch. Instrument Tray (optional)Provides a movable instrument tray within the sterile field. There is a curved metal rod on either side of the tray arm that allows for creation of a sterile pouch when used with sterile tray arm cover. The tray is capable of accommodating a variety of positions in the operating room environment: right, left, front and rear of the surgeon as well as the front of the bed. The tray is height adjustable.WARNINGS!The maximum allowable load on the instrument tray is 20 lb (9 kg). If the load exceeds this limit, the tray arm will automatically lower itself in order to avoid tipping the system over. Additionally, if the instrument tray is positioned over a patient, a mayo stand should be placed beneath it to avoid a potential collapse of the tray arm onto the patient. Place the instrument tray in the stored position (see Figure 2-1) prior to transportation to avoid a situation that could cause the system to tip.IV Pole with Bottle Hanger (optional)A bottle of BSS® or BSS Plus® irrigating fluid is hung from the hook on top of this pole. The IV pole is used to raise and lower the bottle height, causing irrigation pressure to increase or decrease.WARNING!Do not use Legacy® IV pole extender with Constellation® Vision System IV pole.•••

2.4 8065751025Constellation® Vision SystemCaster WheelsFour large caster wheels support the Constellation® Vision System. The wheels rotate 360º for ease of system mobility, and have a locking lever to secure the system in place. The wheels should always be locked (handle up) when the unit is in use, and unlocked when being moved.IlluminationPrimary illumination is provided by two independently controlled ports located just below the display. The light output at these ports is based on xenon arc lamp technology that generates high brightness white light. Each port will allow the use of 20, 23, and 25 GA ACMI Terminated fiber probes. For 20 GA probes, the port provides a minimum of 50 lumens at 100% setting (0-200 hours), and for 25 GA probes, the port provides a minimum of 15 lumens at 100% setting (0-200 hours). Auxillary illumination is available as an optional feature that provides for two additional channels of high brightness white light.Laser (optional)The optional laser module is used for retinal and macular photocoagulation; iridotomy and anterior segment procedures; trans-scleral cyclophotocoagulation; laser trabeculoplasty, trans-scleral retinal photocoagulation, and other diode laser treatments.Footswitch ConnectorThe footswitch connector is located on the front panel and is used to connect the Constellation® Vision System footswitch to the console. (In monolith configuration, the footswitch connection is made in the front of the base.)HandlesHandles are located on the sides and back of the instrument, and should always be used to move the unit. For greater safety and control, the unit should be pulled, not pushed.CAUTIONThe system must be moved carefully, otherwise the system could tip over and become damaged. Do not push or pull the unit by the display, the tray, or the IV pole. Handles located at the rear and sides of the unit are provided for moving the instrument. The unit should be pulled and not pushed, especially over elevator and door thresholds.
8065751025 2.5Constellation® Vision System Figure 2-2 The Constellation® Vision System Rear PanelREAR PANELBarcode ReaderThe barcode reader allows the user to quickly scan any pak or related consumable at any time during the case to input critical information about the pak into the system. The information enables the system to direct the operating room staff to any special requirements of the device, offer in-depth videos, and automatically prime the device once connected (if required). When the operator scans a barcode through the reader and the system recognizes the barcode as one that is preconfigured in the system, it produces an audible beep and adds the associated consumable to the current surgical case. If the barcode is not recognized by the system then an advisory message is displayed.Barcode Reader(Optional)Illuminator Module EjectAux.

8065751025 2.7Constellation® Vision System FOOTSWITCHFunctional operations of the Constellation® Vision System console are controlled by the footswitch shown in Figure 2-3. The footswitch consists of a treadle, left and right horizontal/vertical switches, left and right heel switches, and a tension adjustment knob. An advisory popup window is displayed if the footswitch is not connected.Generally, the treadle is used to provide control of a parameter, such as vacuum, with the treadle's angle of depression proportional to the parameter output. In some modes of operation, the treadle is used to provide on/off control of a function, with any depression resulting in a fixed output of its parameter. The footswitch treadle is used in a mode-dependent fashion during system operation. In U/S mode for example, when the treadle is depressed its range of travel is divided into ranges 0, 1, 2 and 3. Each range, except range 1, is separated from the previous range by a detent. Detent firmness levels are programmable in the Doctor Settings menu which is discussed later in this section of the manual (see Settings). The footswitch icon located in the upper left corner of the screen displays the current treadle position.Right and left switches are used to enable and disable system functions. The switches are nudged sideways (horizontal) for some functions, and pressed down (vertical) for others. The tension adjustment knob, located on the front of the footswitch, is used to adjust the pressure needed to depress the treadle.

2.8 8065751025Constellation® Vision SystemREMOTE CONTROLThe Remote Control is a wireless, handheld, battery operated device that uses infrared light to communicate with the Constellation® Vision System console. Each of the different keys on the Remote Control unit has its own unique key code that is transmitted to the Constellation® Vision System console when the key is pressed. The transmitted key codes are translated into commands that control the Constellation® Vision System console.Figure 2-4 shows the Remote Control and the keys provided. When a Remote Control Transmitter key is pressed, the Constellation® Vision System console determines whether or not the key press was valid and generates an appropriate valid or invalid key tone. Global Controls Up/Down KeysNext Step KeyParameter ValueAdjustment KeysGlobal ControlsNavigation KeyBacklight button (2)Enter KeySurgery ScreenNavigation Keys:Left/Right; Up/DownPrevious Step KeyFigure 2-4 The Constellation® Vision System Remote ControlThe Remote Control is divided into three sections from top to bottom. The three sections of the display screen are 1) the top section is for Global Selection and adjustments of global values, 2) the main (middle) window is for surgery screen navigation and parameter settings, and 3) the bottom section is for selecting steps and enabling/disabling selected controls. Some items on the Constellation® Vision System console display screens are not accessible with this Remote Control unit. Global Control Up/Down Keys The Global Control up/down keys on the remote control function as they do on the Host Display touchscreen. Each individual press of the up arrow key increments the setting on the selected global control in the Globals panel on the touchscreen. Each individual press of the down arrow key decrements the setting on the selected global control. To move rapidly up or down, the key is pressed and held until the desired setting is reached. The Global Control keys are only valid in the Setup and Surgery screens, and are not valid when any pop up dialog is displayed.
8065751025 2.9Constellation® Vision System Global Controls Navigation KeyThe function of the Global Controls Navigation key is to navigate to any control on the Globals panel and be able to select a specific control (refer to Figure 2-6 to see the Globals panel). Pressing this button the first time selects the Infusion Control which is the first control on the Globals panel. The selected control will be highlighted with a golden outline. Each successive press of the Global Controls Navigation key causes the next available control on the Globals panel to be selected. An exception to this rule occurs if the Infusion Control is selected. In this case the IOP Compensation button on the control is selected to adjust IOP settings. Surgery Screen Navigation Key The Surgical Screen Navigation key is a four way switch that enables a remote control user to move up, down, left and right on the surgery screen and to select the controls and/or panels on the screen. Once a control is selected, the user can press the Parameter Value Adjustment keys to increase/decrease the control parameters. When the ON/Off button is highlighted with a gold border, pressing the Enter key alternately toggles the control ON and OFF.The Navigation Key button is valid when the Surgery screen is being shown, but is invalid when a dialog is displayed. Parameter Value Adjustment Up/Down KeysThe Parameter Value Adjustment Up/Down keys are used to adjust settings (parameters) in a Surgery Control Panel that has adjustment arrows (i.e., pressure, vacuum, cut rate). Surgery control panels are selected via the Navigation Key and a blue border indicates that the panel is selected. Previous Step/Next Step KeysThe Previous Step/Next Step keys are used to move left and right through the surgery steps at the bottom of the Surgery screen (see Figure 2-29). In the Surgery screens, when a step is selected by using the Previous Step/Next Step key on the remote, the system selects the next step to the left or to the right. If it is a valid step, it will be selected immediately without having to press any other keys. Continuing to press the keys causes the system to move through the steps and wrap around to the beginning step. It is not possible to access the submodes from the Remote Control Unit. The Previous Step/Next Step keys can also be used in an information dialog to select a button (e.g., OK, Cancel, Save, etc.). Enter KeyThe Enter key is used to enable/disable a selected control. For example, if the vacuum control is selected and the Enter key is pressed, the vacuum control is disabled and the ON/OFF button is grayed out.
2.10 8065751025Constellation® Vision System Remote Control Batteries When the batteries in the remote control are low, the status message “Remote Battery Low” will appear in a popup dialog the first time a key is pressed after the system is turned on. The message will disappear after new batteries are installed and a remote control key is pressed. A battery holder inside the remote holds three (3) AAA (LR3) batteries. To replace batteries: Loosen two captive screws on the rear cover with a standard slotted screwdriver and remove cover. Replace old batteries and replace cover (correct battery positions are identified inside each battery slot). When closing the cover it is important that the rubber buttons slide into the slots in other half of the remote without binding (see Figure 2-5).To check correct installation of batteries, press a backlight button on the side of the remote and verify that the remote control buttons illuminate, then turn off after a few seconds. If illuminated buttons don't turn off, rubber buttons are not properly inserted into slots, so you must repeat the procedure. Dispose of batteries following local governing ordinances and recycling plans.1.2.3.4.Rubber Buttons(2)must enter slotswithout bindingFigure 2-5 Remote Control Battery Replacement
8065751025 2.11Constellation® Vision System Select Remote Control Channel The remote control can be configured to operate on one of four channels. This feature allows four remote controls to independently control four Constellation® Vision Systems operating in the same room or area. Remote controls are factory preset to channel A. For proper remote operation, the Constellation® Vision System must be set to the same channel as the remote. The Option/System Settings/Remote Control window allows the selection of four remote receive codes: A, B, C, & D. This selection must correspond to the channel selection on the remote control.
