Device Description

Technical Specifications

The Stryker X8000 Light Source is a light-generating unit designed to illuminate surgical sites during endoscopic applications. The X8000 uses a 300-watt xenon bulb to generate light, which it delivers to the surgical site via a fiberoptic light cable. The X8000 is compatible with all Stryker light cables, and, with the proper light cable and adapters, can connect to any flexible or rigid endoscope. The X8000 is equipped with Electronic Scope Sensing Technology (ESST), a special safety feature that helps prevent accidental burns caused by a light cable that is not connected to the scope. When operated with an ESST light cable, the X8000 senses when the scope and the light cable are separated and places the light source in Standby mode. In Standby mode, the X8000 will reduce light output to a minimum, preventing the light cable from generating excessive heat.

Basic Maintenance Cleaning the X8000 Caution 1.

2.

Unplug the X8000 before cleaning the unit. As needed, clean the external surfaces of the X8000 using a cloth or sponge dampened with a mild detergent or disinfectant. Clean and maintain the light cable according to the manufacturer’s instructions.

Caution

Do not use any abrasive cleaners. Do not allow any liquid to drip into the unit.

Caution

Do not sterilize or immerse the X8000.

Replacing the Bulb Module Replace the bulb module when the LCD indicates 500 hours or when the bulb no longer sufficiently illuminates the surgical site. If possible, replace the bulb module between surgical procedures. Warning

To replace the bulb module, 1. Power down the X8000 and wait at least three minutes for the bulb to cool. 2. 3.

Caring for the Bulb Module The X8000 uses a Xenon bulb, which has a guaranteed life of 500 hours when used properly. Always follow these guidelines to ensure maximum bulb life: 1. If the bulb is touched, clean the bulb face with alcohol and a cotton swab. Dirt or oil on the bulb face will cause the bulb to heat unevenly and fail. 2. Do not power on and off the bulb in rapid succession. Allow the bulb to run for at least five minutes once it has been powered on. Failure to do so can cause the bulb to rapidly darken and fail. Caution

10

The X8000 has been designed to start the bulb under most conditions, even when it is hot. However, if the bulb does not start within 10 seconds after the X8000 has powered on, turn the unit off and wait at least five minutes for the bulb to cool before restarting. Further attempts to start the bulb can damage the bulb and possibly the internal circuitry.

During operation, the bulb and the housing around the bulb may be hot. Wait at least three minutes for the bulb to cool before handling it.

Open the bulb door. Rotate the bulb module handle to the right, grasp it, and withdraw the bulb.

Warning

Do not reach inside the bulb door for any reason other than replacing the bulb module. Touching parts other than the bulb module may cause burns or product damage.

Warning

Do not touch any part of the bulb module except for the handle. The module may be very hot and cause burns.

4.

5. 6. 7. 8.

Insert the new bulb module (Stryker part number 220-201-000) along the guide rails until it is fully seated on the mating connectors. Rotate the handle to the left to secure the bulb module within the light source. Close and latch the bulb door. Power on the unit. Power on the bulb (if not already on) and verify that the LCD displays the bulb hours as “0.”

Note

Using a non-Stryker replacement bulb module will result in no light output.

Caution

Do not operate the X8000 with a burnedout bulb or with no bulb installed.

Replacing the Fuses 1. 2. 3.

Unplug the light source from the AC outlet and remove the power cord from the rear of the unit. Unlatch the fuse holder and remove the fuse(s). Replace the fuse(s) with fuse(s) of the same value and rating.

Troubleshooting Problem No light output

Possible Solution • • • • • • • • • •

Too much or too little light output

• • •

Ensure the AC power cord is properly connected to a hospital-grade power outlet and the inlet on the rear console panel. Ensure the power switch on the front panel is powered on. (It will illuminate when powered on.) Ensure all fuses are operating. Ensure the bulb is properly seated in the bulb housing. The bulb handle should be turned all the way to the left within the light source. Ensure the bulb is in operating condition. Replace the bulb if necessary. Ensure the light cable is correctly engaged with the cable port. As a safety feature, the X8000 will provide no light output unless a fiberoptic light cable is properly seated in the cable port. Ensure the bulb access door is completely shut. Check for error codes E-1, E-2, E-3, E-4 or E-5. See the Error Code Definitions section of this manual for details. Check that vents are not obstructed. If the safety shutoff has been activated, please return the X8000 for service. Please see the Component Replacement section of this manual for additional information.

Ensure the light cable is correctly engaged with the cable port. Ensure the bulb has adequate bulb life remaining. The bulb has a warranty of 500 hours. Ensure the X8000 is in Run mode. (The Run LED should be illuminated.) If necessary, press the Mode button to switch from Standby to Run. If the unit remains in Standby: 1. 2.

•

Ensure the light cable is correctly engaged with the cable port. If an ESST cable is connected to the X8000, ensure the cable is attached to the scope using an ESST scope adapter. Use the up/down buttons to adjust the brightness. Ensure the fiberoptic cable is transmitting light properly. Hold the light-source end of the cable to an overhead room light and look into the scope end of the light cable. If the pattern contains any black spots, the light cable may be worn out and may require replacement. Ensure the light cable is of an adequate size for the application. The cable diameter may be too small to provide adequate light transmission for the medical video camera in the endoscopic application. Ensure the electronic shutter on the camera is operating properly to control the video signal brightness. If further light reduction is required, decrease the light source brightness with the down button.

Check the voltages on the control board test points TP22 and TP23. • If the test points read 12V and 0V respectively, then the ballast is faulty. Replace the ballast. • If the voltages are in the vicinity of 5.5V and 7V respectively, proceed to step 2. Visually check if the bulb door is properly closed with the cover or a stand-alone magnet. If necessary, close the door. Visually check if the light cable is properly inserted into the jaw. If necessary, reinsert the cable. Visually check if the bulb has the one-wire memory chip. If it does, ensure the chip makes contact with the bulb mount board connector. If necessary, adjust contact between the chip and the connector. Using a multimeter, electronically check the following test points on the control board. Each test point should read 3.3 volts. • PD1-reads 3.3 volts if the one wire chip is detected by the control board. If PD1 reads 0 volts (and PD2 reads 3.3 volts), try a different bulb. Push the bulb firmly towards the plastic separator panel to ensure contact.

6.

B.

PD2-reads 3.3 volts if the door reed switches are closed. If PD2 reads 0 volts, - Check if the reed switches on the bulb mount boards are soldered properly. If necessary, repair the soldering. - Check for shorts using the magnet on the reed switch. Repair/replace as necessary. - Check if the cable wire colors are correctly oriented. Adjust as necessary. • PD3-reads 3.3 volts if the fans are functioning properly • PD4-reads 3.3 volts if a regular light cable is inserted. If PD4 reads 0 volts, remove the front panel and check if the beam sensor is properly positioned and connected to the display board. Adjust as necessary. • PD5-reads 3.3 volts if an ESST light cable is inserted. If PD5 reads 0 volts, remove the front panel and check if the beam sensor is properly positioned and connected to the display board. Adjust as necessary. If none of these help, contact Technical Support at +1.800.624.4422.

Bulb does not turn off

If the bulb turns on immediately after AC power is applied to the light source, proceed to diagnosis strategy C, “Bulb ignites immediately upon system startup.” If the bulb ignites after the regular startup sequence but then will not turn off, perform the following steps until the source of the problem is identified. 1. Remove the light cable from the jaw. 2. Open the bulb door or remove the magnet from the reed switches. 3. Using a multimeter, check the following test points on the control board: • PD2-If PD2 reads 3.3 volts, the reed switches are faulty. Replace the reed switches. • PD4 and PD5-If either PD4 or PD5 reads 3.3 volts, the light cable sensor (beam sensor) is faulty. Replace the light cable sensor. 4. If PD4 or PD5 reads 0 volts, measure the voltage difference between TP22 and TP23. • If the voltage difference is around -1.3 volts, replace the ballast. • If the voltage difference is around 12 volts, proceed to step 5. 5. Measure the voltage level for TP32. • If TP32 reads 0 volts, replace the control board. (See the Repair/Replacement Procedures section of this manual.) • If TP32 reads 3.3 volts, proceed to step 6.
