1.0 INTRODUCTION

1.2.1

t is recommended that personnel study this manual before attempting to operate and/or clean the ConMed Linvatec LS7700 300 Watt Xenon Light Source and accessories. The safe and effective use of this equipment requires the understanding of and compliance with all warnings, cautionary notices, and instructions marked on the product, and included in this manual.

I

1.1

1.

Do not attempt to open or service the light source chassis. There are no user-serviceable parts inside. Removing the cover may introduce an electric shock hazard by exposing you to dangerous high voltages or other risks. If the system malfunctions, return it for service immediately.

2.

Use of this light source and the accompanying light guide can cause the scope tip to get hot as a result of high intensity light. Do not allow the light emitting end of the light guide to contact either the patient or the surgical drape. This can cause the drape to ignite and potentially cause severe burns to the patient and / or operating room personnel.

3.

Do not use in the presence of flammable anesthetics, gases, disinfecting agents, cleaning solutions, or any material susceptible to ignition due to electrical sparking. There is a possibility of explosion.

4.

Do not use a cardiac defibrillator on a patient without first removing from the patient the endoscope to which the light source is attached.

5.

Do not use in surgical procedures requiring direct illumination of the eye.

6.

This device is designed for use in standard medical environments. Components of the system that are meant for patient contact are constructed from biocompatible materials.

Intended Use

The ConMed Linvatec LS7700 300 Watt Xenon Light Source is intended to be used with an endoscope to provide illumination during endoscopic procedures.

1.2

Safety Information

This equipment is designed for use by medical professionals completely familiar with the required techniques and instructions for use of the equipment. Read and follow all warning and cautionary notices and instructions marked on the product and included in this manual. It is important to read, understand, and comply with all of the following safety precautions. Failure to follow these precautions could result in injury to the patient or user or cause damage to the LS7700 Light Source or associated equipment. After each use, thoroughly clean the unit and accessories (See “3.2 Cleaning” on page 10). 1

Warnings

1.2.2

1.

2.

11. Do not operate the light source in an explosive atmosphere.

To avoid fire hazard or electrical shock:

12. Do not allow foreign objects inside the light source.

Prior to each use, the light source and all associated equipment must be inspected for proper operation.

13. Do not disassemble the light source. There are no user-serviceable parts inside.

Use only non-conducting light guides (optical cable). Verify that the light guide is dry and free from cleaning solution residue before plugging it into the light source.

14. Never spill liquids of any kind on the device or immerse it in liquids. 15. Only plug the light source into a properly grounded hospital-grade outlet.

3.

Use only the power cord specified for this device.

4.

Do not use plug adapters or extension cords; such devices defeat the safety ground.

5.

Do not excessively bend or kink the power cord. Always inspect cords for signs of excessive wear or damage. If wear or damage are found, discontinue use and replace immediately.

1.

Do not use the light source with incompatible equipment or accessories that are not authorized by ConMed Linvatec. Doing so may void certifications and/or warranties.

6.

Unplug the power cord from the outlet when performing any kind of cleaning or general maintenance, such as changing the lamp assembly.

2.

3.6

The power supply is a switch mode type with a built-in, high voltage lamp ignitor and current regulator. The fans are powered from an auxiliary 12VDC power output of the main supply. An interlock switch in the lamp access door removes power from the fans and lamp supply outputs including all DC and AC voltage and current. When the door is open, power remains connected to the fuses and the two EMI filters inside the unit, as well as some internal components in the power supply. See the schematic diagram for details.

Theory of Operation

The xenon light source uses a replaceable short arc xenon lamp with an integral elliptical reflector. The lamp is designed to produce a very small high brilliance electric arc in a sealed xenon envelope to simulate the spectral content of sunlight for the best video camera performance. The arc also produces IR (heat) that is filtered by two hot mirrors positioned between the lamp and the light guide.

An EEPROM chip mounted on the lamp module tracks lamp life for easy and accurate front panel display. A microcontroller controls two communication ports, all front panel controls and indicators, shutter motor, and lamp life operation. The microcontroller board is powered by the auxiliary 12VDC from the lamp supply.

To operate an arc lamp, a special power supply is needed since the start-up process is not a simple matter of applying power. In the off condition the arc has very high impedance. Therefore, a high voltage (23KV min. balanced) must be applied to develop a conduction path from the anode to the cathode. Following the very high voltage, an intermediate voltage is applied as the impedance of the arc path drops and the arc becomes larger. In the third phase of the start-up sequence the voltage falls between 11.5 - 15 VDC as current regulation takes over to sustain the now fully developed arc. The unit continues to operate in this current regulated mode until the power is removed by the front panel “POWER” button. The temperature on the surface of the lamp can be very high, therefore, cooling is very important during operation. The lamp must be allowed to cool in accordance with the included instructions before any handling is attempted. The lamp is very fragile and can easily break explosively since the lamp is under high pressure.
