Endoscopic Video Cameras

Introduction

Endoscopic video cameras are used most

often with rigid scopes; occasionally with

flexible scopes for less invasive procedures.

Each camera head contains a video chip

(CCD) that converts the image in view into

an electronic signal.

Introduction

Signals are received at the console from the camera, through the cable. The console processes the image and forwards the video signal to the monitor.

Most cameras work only with consoles of the same manufacturer.

The camera is attached to the eyepiece of the scope by a coupler.

Cameras are found in use in surgery;

orthopedic, urology, obgyn, & general in

hospitals, outpatient and free standing

surgery centers.

Many facilities are unaware that an

alternative to the manufacturer exists for

repair.

Selling Camera Repair

OEM’s do their best to convince the

customer that they alone are qualified to

repair their cameras. OEM’s, such as

Stryker , do not manufacturer all the

electrical and cable components for their

cameras. They purchase pre-manufactured

components and assemble them into their

cameras. Ex : 1188 cable

Common complaints :

Visual damage; hole or cut in cable.

Video noise.

Cloudy/foggy image, color blotches.

Won’t white balance.

Selling Camera Repair

These problems are caused by breakage or

disconnects at the connector assembly most

often. Fluid invasion or CCD circuit failure

are also seen. Connector breakage occurs as

a result of repeatedly bending/twisting the

cable where it connects to the camera.

Selling Camera Repair

Fluid invades the camera through cuts/holes

in the cable, through worn/damaged seals

(repeated sterilization) or by simply

forgetting to apply the soak cap prior to

cleaning. CCD circuits may fail over time

but are historically very dependable and

represent about 15% of problems.

Selling Camera Repair

It is not uncommon to have the pigtail

(cable extension) stretched to the point of

damaging cable components and

connectors.

Damage naturally occurs from frequent use,

handling and cleaning.

Initial Camera Repairs

Beginning in April 2006 we initiated repairs

on the Stryker line of cameras. We now are

a full service camera repair company, which

includes cameras, processors, light sources,

couplers and pigtails. Our current warranty

rate is 3.9%, a number that is under constant

review.

We will grow our service capabilities as

new cameras come onto the market.

Presently we are examining the Dyonics

560 and Dyonics 470H autoclave prism

all of which will enter R&D as soon as

possible.
