Olympus OLYMPUS Evis Exera CV-160 / CLV-160 – Colonne d’endoscopie

Olympus CV-160 – EVIS EXERA Video System

The Olympus CV-160 is a high-performance video endoscopy system designed to fully utilize the capabilities of EVIS EXERA 160 Series endoscopes. It provides high-resolution imaging, enhanced color reproduction, and an enlarged display to facilitate the observation of fine details.

High-Resolution Imaging

The CV-160 incorporates an advanced video signal processing system that produces clear, detailed images. It improves the visibility of fine mucosal structures and subtle color variations, helping physicians observe anatomical details during endoscopic examinations.

• Structure Enhancement: Electronically enhances fine details and mucosal textures without significantly increasing image noise.
• Edge Enhancement: Electronically emphasizes image edges to improve the sharpness of endoscopic images.
• Adjustable Enhancement Levels: Structure and edge enhancement can be selected at Low, Medium, or High levels.
• Adjustable Contrast: Normal, Low Contrast, and High Contrast modes allow the image appearance to be adapted to examination requirements.

Display and Observation

The CV-160 provides several display functions that allow the image presentation to be adapted to the examination and help physicians focus on areas of interest.

• Full Height Mode: Uses the available screen height to display a larger endoscopic image.
• Medium Display Mode: Provides an appropriately sized image presentation on the monitor.
• Image Size Selection: The size of the endoscopic image can be adjusted using the keyboard or the endoscope switch.
• Freeze Function: Allows a still image to be displayed using the endoscope switch, keyboard, or OVC switch.
• Iris Mode Selection: Average mode is intended for normal observation, while Peak mode is useful for observing a small area that appears particularly bright.

Color Management and White Balance

• Automatic White Balance: Can be activated from the front panel.
• White Balance Memory: Settings are retained in memory after initialization for EVIS EXERA 160 Series endoscopes.
• Color Tone Adjustment: CHROMA control provides ±7 levels of adjustment, with R and B settings also adjustable by ±7 levels.
• Color Bar: Displays a color test pattern using the “Color Bar” button on the keyboard.

Automatic Gain Control

The AGC (Automatic Gain Control) function electronically amplifies the image when illumination becomes insufficient, particularly when the distal tip of the videoscope is positioned too far from the area being observed.

Scope ID Function

The CV-160 features an endoscope identification function that retrieves information stored in the memory chip of EVIS EXERA 160 Series endoscopes and displays it on the monitor.

• Endoscope model
• Serial number
• Number of uses or connections to the CV-160
• Comments
• Inspection period
• Maintenance and warranty information
• Owner and customer identification number
• Identification version
• Automatic white balance check

Connectivity and Image Management

The CV-160 includes a digital image terminal that allows still endoscopic images to be transferred directly to a computer using dedicated interface software.

• Digital Communication Port: 100BASE-TX Ethernet.
• Digital Image Terminal: Transfers still images to a PC.
• Video Outputs: Composite VBS, Y/C, and RGB outputs with simultaneous output capability.
• Video Source Selection: Allows selection between the image from the endoscope and an image from peripheral equipment.

Patient Data Management

Patient information can be displayed on the monitor using the keyboard and incorporated into the examination workflow.

• Patient identification number
• Patient name
• Sex and age
• Date of birth
• Date and time
• Image number
• VTR status
• Image quality selection
• Physician
• Comments

Pre-procedure patient information can be stored for up to 40 patients, including identification number, name, sex, age, date of birth, and physician information.

Peripheral Equipment Control

The CV-160 allows certain auxiliary devices to be controlled using the endoscope remote switch, front panel, or keyboard.

• Monitor
• VTR
• Video printing equipment
• Digital cassette video recorder
• Rinsing pump

Ergonomics and Design

The CV-160 front panel uses large membrane keys and indicators designed to simplify system operation. Its keyboard is designed for ergonomic use and can be integrated into the dedicated system cart.

When combined with the CLV-160 xenon light source, the CV-160 features a more compact design than previous models. The complete system can be installed on a dedicated cart together with a video monitor and various peripheral devices.

Setting Memory

Several front-panel settings are retained even after the system is switched off.

• Color
• Image enhancement
• White balance
• Iris

Parameter Reset

The RESET function restores various system parameters, including image source, iris, enhancement, color, AGC, display mode, contrast, printer lock, keyboard mode, printer mode, and print quantity.
