Welch Allyn LCI-200CE Illumination and Imaging System

Introduction

The Welch Allyn LCI -200CE Illumination and I maging System is fundamentally different from any other
illumination or video system. In this product, Welch Allyn has combined a compact light source with
a very small remote video camera which can be attached to any number of rigid or flexible scopes. By
engineering both the video and the illumination end of the product Welch Allyn is able to produce a very
small, highly efficient product. Furthermore, by combining the lighting and imaging in a sing le packag e,
Welch Allyn has dramatically decreased the burden of system setup and has eliminated the need for the
system white balance. The result is a compact, affordable lighting and video sy stem for rigid and flexible
endoscopic procedures.

Indications

Use of the Welch Allyn LCI-200CE Illumination and Imaging System is indicated whenever video
imaging is preferred over standard optical eyepiece imaging. The product is designed to provide video
imaging for a wide range of rigid endoscopes as well as flexible endoscopes. The LCI-200CE itself is
not a scope; it merely provides video imaging for any existing scope. For indications of use with each

of thes e rigid and flexible scopes, the user must consult the operating manual for the specific rigid or
flexible scope. The LCI-200CE must only be used with endoscopes that are approved for their indicated
use. This product must only be used by qualified medical personnel.

Contraindications

The use of the Welch Allyn LCI-200CE is contraindicated when a video image is not the preferred
method of endoscopic visualization. For specific contraindications for various rigid and flexible scopes,
the user must consult the operating manual for the particular scope being used.

section for recommended isolation transformers and proper measuring techniques.

CAUTION: Always remove camera system from patient before connecting/disconnecting Camera Head
to Imaging and Illumination System.

When possible, keep the Imaging and I llumination System out of patient field. Alway s remove the Power
Box from patient field while connecting/disconnecting the Camera Head.

Do not sterilize the Power Box. Refer to Cleaning and Sterilization section for cleaning instructions.

This TYPE B Imaging and Illumination System is recommended for use with TYPE F floating
endoscopes only. This is necessary to meet the requirements of IEC601-2-18 for a TYPE BF system.

Care should be exercised during procedures, such that fluids do not migrate across insulations between
the TYPE B camera head and TYPE F endoscopes.

External equipment, which will be connecte d to sig na l input and signal output parts or other connectors,
shall comply with relevant IEC standard (IEC 601 series for medical electrical equipment). In addition,
all such combinations - systems- shall comply with the standard IEC 601-1-1 (Safety requirements for
medical electrical systems).

Any pers on who c onnec ts e xter na l equipme nt to sig na l input a nd sig na l output parts or other connectors
has formed a system and is therefore responsible for the sy stem to comply with the requirements of IEC
601-1-1.

WARNING: Replace fuses as marked. See Fuse Replacement Section.

WARNI N G : T h e h i gh intensi t y ligh t at the fro n t o f t he Power B ox, at the tip of the Fiber Optic Bundle,
and at the tip of the endoscope may give rise to high temperatures. To minimize the risk of injury , avoid
prolonged contact with tissue.

Be sure that the Fiber Optic Bundle and Camera Head are plugged into the Power Box before
turning the power ON.

Do not switch the LCI-200CE system ON and OFF in ra pid succession.

Doing so will dramatically
shorten lamp life. The lamp needs to "cool down" for approximately 10 to 15 seconds between uses; if
the user turns the LCI-200CE from ON to

OFF

and then immediately back ON, the lamp will not start,

and the LAMP SERVICE light will illuminate.

Since the LCI-200CE uses a custom, proprietary Welch Allyn lamp

always have a spare lamp available

for lamp replacement.

Always attach the soaking cap to the camera connector before soaking.

Do not disconnect the Optical Coupler from the Camera Head before soaking

, as this will make it

possible for fogging to occur between the Camera Head and the Optical Coupler.

Do not remove the camera cable from the Power Box during operation.

For best results, the camera
cable should be plugged into the Power Box before the Power Box is turned ON. Although no damage
will occur to the camera or CCD if the connection is made after the power is turned ON, the camera will
temporarily shut down requiring the operator to restart the unit.

Do not store liquids above or on the LCI-200CE.

Do not attempt to service any part of this product except for lamp and fuse replacement.

WARNING: If used during invasive surgery, a spare system should be kept on standby.

Welch Allyn LCI-200CE Illumination and Imaging System

System Description

The Welch Allyn LCI -200CE uses a proprietary Welch Allyn lamp to provide high quality illumination
and a state-of-the-art SONY camera with HyperHAD to produce a brilliant video image.

The Welch Allyn lamp, covered by several patents, is a miniature arc lamp; it produces the same color
temper atu re i llumination as a high wattage Xenon arc lamp, but generates only a fraction of the heat.
Whereas most Xenon light sources weigh over 25 pounds, the tiny Welch Allyn lamp allows the
Illumina tio n and Imaging systems to be combined in a box weighing less than 5 pounds. The Welch
Allyn lamp produces a virtual "point source" of light, and is specifically designed to couple with a fiber
optic bundle. Light output is modulated based on the needs of the camera.

The camera used in the LCI-200CE is an advanced SONY one-half inch CCD camera. This camera uses
the proprietary HyperHAD microlens architecture, whereby hundreds of thousands of tiny light g athering
lenses sit on top of the pixels on the CCD. These miniature lenses make the CCD extraordinarily
sensitive to light. The SONY also operates in both Auto-Shutter and Fixed-Shutter speed modes,
depending on the light levels required by the camera.

The three major components of the LCI-200CE are shown in the diagram below.

Figure 1: Welch Allyn LCI-200CE

Welch Allyn LCI-200CE Illumination and Imaging System

Component Description

Component 1. The Power Box houses the lamp, camera processor and power supply. It is described in

more detail below.

Component 2. A Fiber Optic Bundle, using an ACMI adapter on the Power Box end and a universal

adapter on the scope instrument end, is provided. Using any number of adapters, the
Fiber Optic Bundle is attached to any rigid or flexible scope.

Component 3. The remote camera is packaged into an ergonomically designed handpiece, specifically

designed for endoscopic applications. A C-Mount Optical Coupler may be attached to the
remote Camera Head, allowing the camera to adapt to the eyepiece of any rigid or flexible
endoscope.

Power Box

The Welch Allyn LCI -200CE Illumination and I maging System is fundamentally different from any other
system available today , in that it combines the illumination and the video processing in a single, compact
box. Instead of having a separate 300 watt Xenon light source and video processor these two components
are combined in the L CI Power Box. The heart of the Power Box is a Welch Ally n lamp which provides
superior illumination in a package that is a fraction of the size of typical endoscopic light sources. The
light output provided by this lamp is automatically modulated by a mechanical shutter which alters light
output based upon the needs of the camera. The LCI-200CE also houses the video processor for the
camera; the camera used is a state-of-the-art SONY incorporating microlenses, high resolution, and a
continuous, "non-stepping" Auto-Shutter mode for high performing light control that works in tandem
with the mechanical light control shutter.

In addit io n to being smaller, the LCI-200CE Power Box is easier to set up and use than conventional
endoscopic video systems. Since the light source and camera are integrated into a single package, there
is no reason to white balance the LCI-200CE. With the LCI-200CE there are no cables that need to be
connected between a separate light source and video processor. And the LCI-200CE operates exclusively
in automatic light control mode, meaning that there are no adjustments that need to be made for light
control. However, if the user wants to increase the overall picture brightness, this adjustment can be
made on the front panel. Note that the LCI-200CE will still operate in automatic light control mode; only
the overall picture brightness will change.

The LCI-200CE Power Box is driven by a universal switching power supply , which accepts 100-240 V~,
50-60Hz without having to be adjusted. This power supply automatically senses line voltage and makes
the correct adjustments for any line input. The power supply is also Medical Grade and is approved for
medical standards from UL, CSA, TUV, and IEC.

Diagrams of the front and rear panels of the Power Box on the opposite page. Detailed descriptions of
the panels are also provided on the following page.

The single power switch located on the front panel provides power to the lamp, as well as to the camera
system and the attached CCD. The power should only be turned on when the Fiber Optic Bundle and

Camera Head are plugged into the Power Box. When the power is turned to the ON position, the power

LED is illuminated, the lamps take 4-6 seconds to warm up, and the camera is immediately started.

Page 9

Welch Allyn LCI-200CE Illumination and Imaging System

In the middle of the front panel is the Camera Connector Port. The Camera Head should be plug g ed into
this connector before the unit is turned ON. The camera connector should be dry of any liquid cleansers

when it is plugged into the Power Box connector. The camera connector should be plugged into the
Power Box before turning the power

ON.

The light port is found on the right side of the front panel. This lig ht port accepts only an ACMI standard
Fiber Optic B undle c onne c tor . Welc h A llyn provides this Fiber Optic Bundle for rigid scopes, and also
provides adapters so that flexible scopes can be plugged directly into the Power Box. See the next section
for fu rth er details on the Fiber Optic Bundle. The Fiber Optic Bundle must be plugged into this port

before

the power is switched

ON.

Next to the light port is a lamp service indicator which illuminates
when the lamp is near the end of its life. The lamp in the Welch Allyn LCI-200CE typically lasts several
hundred hours, based on a 45 minute ON/15 minute

OFF

duty cycle.

Between the light port and the camera port is a brightness control panel. The LCI-200CE allows the user
to set the overall picture brightness of the Camera System by making adjustments on this control panel.
Pressing the UP arrow makes the overall picture brighter, and pushing the

DOWN

arrow makes the
overall picture darker. Note that, no matter what the setting is, the system always works in automatic
light control mode. The user adjustments only change the overall brightness of the picture. The picture
brightness control defaults to the center position when the LCI-200CE is turned on. The automatic lig ht
control functions by the use of a mechanical shutter which modulates the amount of light required for the
camera. T he shutter speed of the camera remains constant and only the amount of light is modulated.
The automatic light control operates in this mechanical-automatic mode in all positions, with the
except ion of the highest picture brightness position. When the user sets the picture brightness to the
maximum position, the shutter opens to allow the maximum amount of light, and the SONY camera
operat es in Auto-Shutter mode. In this way the user is able to choose both picture brightness and
mechan ical vs. electronic light control modes. In most cases the mechanical light control mode is
preferred.

On the rear panel, a power cord connector is found on the far left side. Next to the power connector is
a fan wi th a protective grill and then the video output connectors. Two S-Video connectors and two
composite video connectors are available; any or all of the connectors can be used at one time. Finally,
on the far right of the rear panel is a potential equalization stud which can be used as a safety ground; it
can also be used to ground the system, particularly when there is a risk of video noise caused by
electrosurgery units.

The LCI-200CE complies with the requirements of EN60601-1, EN60601-1-2, IEC 601-2-18, CAN/CSA

601.1 and UL 2601.

"The CE mark on this product indicates it has been tested to and conforms with the provisions noted
within the 89/336/EEC Electromagnetic Compatibility Directive".

Fiber Optic Bundle

For rigid endoscopy, the Welch Allyn LCI-200CE Power Box r equir e s a F iber Optic Bundle to carry the
light from the Power Box to the rigid endoscope. Welch Allyn provides a 5mm diameter Fiber Optic
Bundle which is designed specifically for the Power Box. This Fiber Optic Bundle has an ACMI adapter
on the Power Box end and a universal light post at the scope end. Scope Adapters are available for the
universal light post to accommodate all rigid scopes. These adapters screw onto the universal light post.
See diagram below:

Figure 4: Fiber Optic Bundle used with Scope Adapters

When snapping the Fiber Optic Bundle into the Power Box, the user will notice a tight connection. Three
ball detents hold the Fiber Optic bundle in precise alignment with the Welch Allyn lamp. This alignment
is cri tic al t o the performance of the product. Because of this tight alignment,

Fiber Optic Bundle should be used

; if other Fiber Optic Bundles are used, the quality of the

only the Welch Allyn

illumination and the image will be compromised.

WARNING: Inserting the light post end of the fiber optic bundle into the power box may result

in severe damage.

Page 11

Welch Allyn LCI-200CE Illumination and Imaging System

Unlike rigid borescopes, which require a separate Fiber Optic Bundle to carry light from the light source
to the scope, most flexible scopes have a Fiber Optic Bundle which runs all the way from the light source
to th e t ip of the scope. In order to accommodate these flexible scopes, Welch Allyn has developed a
number of adapters which convert the fiber optic connector to an ACMI standard. The diagram below
illustrates this with several flexible scopes.

Figure 5: Flexible Scopes with Adapters

These adapters are available from Welch Allyn, and allow any flexible fiberscope to plug directly into
the Welch Allyn LCI-200CE system.

Page 12

Welch Allyn LCI-200CE Illumination and Imaging System

CCD Camera Head and Cable

The CCD camera used in the Welch Allyn Illumination and Imaging System is a high performance, 1/2
inch SONY CCD, using Auto-Shutter, HyperHAD, and an automatic color tracking system. The CCD
is op erated in either fixed shutter speed or Auto-Shutter mode, depending on the picture brightness
control setting. HyperHAD technology, developed by SONY, places a tiny light-gathering lens on top
of each pixel, making the CCD over 2 1/2 times more sensitive to light than the conventional CCD. The
CCD is packaged into a very small, ergonomically designed handpiece, and the cable is packaged in a
sturdy but lightweight neoprene cord, under which is a strong, stainless steel braid.

The Camera Head has a standard C-Mount interface, which can accept any C-Mount Optical Coupler.
Welch Allyn provides a fixed focal length, 35mm Optical Coupler with the LCI-200CE. The LCI-200CE
does not require that the screen image occupy a certain percentage of the total screen.

At the other end of the CCD imager head a connector is permanently connected to the cable. This cable
plugs into the front panel of the Power Module. A connector cap is also provided which must be attached
to the connector before cleaning the Camera Head and Cable. The connector should never be wet when

plugged into the Power Box. The connector should be plugged in before the power button is switched
to the ON position.

System Inspection

Prior to us e insp ect the Camera Cable, head, and connectors for signs of wear. Ensure that the lens
system is securely attached to the Camera Head. Likewise, the Fiber Optic Bundle should be inspected
for abnormalities. Be sure that the proper adapters are used on the Fiber Optic Bundle in order to make
a secure connection between the Fiber Optic Bundle and the scope. Finally, before plugging the Camera
Head into the Power Box, check that it is dry and free of rinsing and/or soaking solution.

System Setup Procedure

1. Plug t h e P ower Box into a hospital grade receptacle. Make either the S-Video, the Composite

Video, or both of the connections between the Power Box and a video monitor.

2. For rigid endoscopy, plug the Welch Allyn Fiber Optic Bundle into the Power Box and connect

the proper adapter to the sc ope end of the F ibe r Optic B undle. Atta c h the F iber Optic Bundle to
the proper scope. For flexible endoscopy attach the proper flexible Scope Adapter to the Power
Box end of the flexible scope. Plug the scope and adapter into the Power Box.

3. Plug the Camera Cable connector into the front panel of the Power Box. Attach the scope to the

Optical Coupler.

4. Turn the power to the ON position.
After turning the power ON the lamp will take 4-6 seconds to complete its warm-up routine. At the end

of that time a high intensity white light will appear out of the scope. Since Welch Allyn integrates the
lamp, fiber optics, and video system into a single product family, there is no need to white balance the

system.
The la m p needs to " cool down" for approximately 10-15 seconds between uses. Attempting to restart

a lamp in less than this amount of time will shorten the life of the lamp.

Leakage Current Test Setup

When the LCI-200CE camera sy stem is used in conjunction with other video accessories (such as printers
and VC R s) , it may be necessary to measure the leakage current of the entire setup. A typical setup is
shown in Figure 6 below. Using a standard leakage tester, this setup will allow the overall system
leakage current to be measured. An isolation transformer must be used if the leakage current exceeds 100
microamperes, in order to conform with EN60601-1 standards. The maximum allowable leakage current
of the patient applied part (Type F endoscope) is 100 microamperes.
