Product Description and Intended Use The Stryker L9000 Light Source is a light-generating unit designed to illuminate surgical sites during endoscopic applications. The L9000 uses light-emitting diode (LED) technology to generate bright, crisp light, which it delivers to the surgical site via a fiberoptic light cable. The L9000 is compatible with all Stryker light cables, and, with the proper light cable and adapters, can connect to any flexible or rigid endoscope. The L9000 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. For more information, refer to the section “Checking the ESST Feature”. When operated with an ESST light cable, the L9000 senses when the scope and the light cable are separated and places the light source in Standby mode. In Standby mode, the L9000 will reduce light output to a minimum, preventing the light cable from generating excessive heat. WARNING

THE SCOPE TIP, SCOPE LIGHT POST, LIGHT CABLE ADAPTER, AND LIGHT CABLE TIP WILL TAKE SEVERAL MINUTES TO COOL OFF AFTER BEING PLACED IN STANDBY MODE AND THEREFORE MAY STILL RESULT IN FIRE AND/OR BURNS TO THE PATIENT, USER, OR AN INANIMATE OBJECT IF NOT USED PROPERLY. DO NOT PLACE THE SCOPE OR THE LIGHT CABLE ON THE PATIENT OR ON THE DRAPES OR OTHER FLAMMABLE MATERIAL, EVEN WHEN THE DEVICE IS IN STANDBY MODE.

Caution

16

Do not abruptly interrupt power to the unit. This will turn off the fan and may cause severe damage to the internal cooling system.

Checking the ESST Feature The L9000 is equipped with Electronic Scope Sensing Technology (ESST), a special safety feature that helps prevent accidental fires or burns to the patient or user caused by a light cable not connected to a scope. This feature will only work if the L9000 is used with an ESST light cable. When operated with an ESST light cable, the L9000 senses when the scope and light cable are separated, and places the light source in Standby mode. In Standby mode, the L9000 will reduce light output to a minimum, preventing the light cable from generating excessive heat. To verify the ESST feature is active, perform the following test before every surgical procedure: 1.

Set up the L9000 system with an ESST light cable and scope, and then power on the system.

2.

Place the L9000 in Activate mode.

3.

Remove the light cable from the ESST scope adapter.

The L9000 should return to Standby mode, indicating that the ESST feature is functioning properly. WARNING

ALWAYS CHECK TO ENSURE THAT THE UNIT HAS SWITCHED INTO STANDBY MODE, BEFORE ASSUMING ESST SAFETY PROTECTION. IF THE UNIT FAILS TO RETURN TO STANDBY MODE, THERE MAY BE A FAULT WITH THE ESST FEATURE. IN THIS CASE, DO NOT ASSUME ESST SAFETY PROTECTION, AND RETURN THE UNIT FOR SERVICE.

WARNING

EVEN WITH ESST PROTECTION, OR WHEN THE L9000 IS IN STANDBY MODE, NEVER PLACE THE TIP OF THE LIGHT CABLE OR LIGHT CABLE ADAPTER DIRECTLY ON THE PATIENT, DRAPES OR OTHER FLAMMABLE MATERIAL, AS BURNS OR FIRE MAY RESULT. THE SCOPE TIP, SCOPE LIGHT POST, LIGHT CABLE ADAPTER, AND LIGHT CABLE TIP WILL TAKE SEVERAL MINUTES TO COOL OFF AFTER BEING PLACED IN STANDBY MODE, AND THEREFORE MAY STILL RESULT IN FIRE AND/OR BURNS TO THE PATIENT, USER, OR AN INANIMATE OBJECT IF NOT USED PROPERLY. DO NOT PLACE THE SCOPE OR THE LIGHT CABLE ON THE PATIENT, ON THE DRAPES, OR OTHER FLAMMABLE MATERIAL, EVEN WHEN THE DEVICE IS IN STANDBY MODE.

Troubleshooting Problem

Possible Solution

No 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. See the “Replacing the Fuses” section of this manual for further instructions. • Ensure the light cable is correctly engaged with the cable port. As a safety feature, the L9000 will provide no light output unless a fiberoptic light cable is properly seated in the cable port. • Check for error codes E-1, E-2, E-3, E-4 or E-5. See the “Visual Display” section of this manual for details. • Check that vents are not obstructed. • If the safety shutoff has been activated, please return the L9000 for service. Please see the section entitled “Safety Shutoff ” in this manual for additional information.

19

Too much or too little light output

• Ensure the light cable is correctly engaged with the cable port. • Ensure the L9000 is in Activate mode. (The brightness level should appear on the LCD.) If necessary, press the Activate/Standby toggle button to switch from Standby to Activate. If the unit remains in Standby: 1. Ensure the light cable is correctly engaged with the cable port. 2.

If an ESST cable is connected to the L9000, ensure the cable is attached to the scope using an ESST scope adapter. • Use the up/down buttons to adjust the brightness. For details, see the “Adjusting the Brightness” section in this manual. • Ensure the fiberoptic cable is transmitting light properly. Hold the light-source end of the cable up 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. Excessive glare in the video

• 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.

Frozen Touchscreen

• Turn off the console, wait 30 seconds, and then turn it back on.
