Olympus OLYMPUS Evis Exera III CV-190 / CLV-190 – Colonne d’endoscopie

Olympus EVIS EXERA III CV-190 / CLV-190 Endoscopy System

The Olympus EVIS EXERA III system combines the CV-190 HDTV video processor with the CLV-190 xenon light source to provide advanced visualization and illumination for modern endoscopic procedures. The system is designed to improve image quality, support efficient clinical workflows and provide broad compatibility with Olympus endoscope platforms.

CV-190 HDTV Video Processor

The CV-190 is an advanced video processor designed to deliver high-quality endoscopic images with enhanced colour reproduction, reduced image noise and minimized halation. It supports HDTV output and provides a range of image processing functions to optimize visualization according to the user's preferences.

• HDTV image processing: Provides sophisticated image quality with enhanced colour reproduction and reduced image noise.
• NBI technology: Narrow Band Imaging provides increased contrast between blood vessels and mucosa and offers approximately twice the viewable distance compared with EVIS EXERA II 180 series scopes.
• Dual Focus: When used with compatible HQ scopes, the processor supports near-focus and normal-focus observation modes.
• Pre-freeze function: Automatically selects the clearest still image from the images captured immediately before freezing.
• Automatic gain control: Electronically amplifies the image when insufficient light reaches the distal end of the endoscope.
• Image enhancement: Structural and edge enhancement modes can be selected to improve the visibility of fine patterns and image contours.
• Three enhancement levels: Allows the user to select the desired level of image enhancement.
• Adjustable contrast: Normal, high and low contrast modes are available.
• Auto iris: Auto, Peak and Average iris modes provide different methods of controlling image brightness.
• Electronic zoom: Allows enlargement of the displayed endoscopic image.
• White balance: White balance can be adjusted using the dedicated button on the front panel.
• Colour adjustment: Red, blue and chroma levels can each be adjusted in ±8 steps.
• Image size selection: The displayed endoscopic image size can be changed from the keyboard.
• Fog-free function: Available when a compatible endoscope is connected.

Connectivity and Video Outputs

• HDTV output: Supports 16:9 and 16:10 output formats for compatible HDTV monitors.
• Analogue HDTV: RGB or YPbPr output can be selected.
• Analogue SDTV: Supports VBS composite, Y/C and RGB outputs.
• Digital outputs: Supports HD-SDI, SD-SDI, DV and DVI interfaces.
• Peripheral connectivity: Link connections simplify cabling and accelerate communication with compatible peripheral equipment.
• Documentation integration: Supports connection with the OLYMPUS documentation system for expanded networking capabilities.
• Remote control: Specified compatible monitors, DVRs, video printers and image filing systems can be controlled from the system.

Image and Patient Documentation

The CV-190 provides integrated functions for image documentation and patient data management. Patient information and recording status can be displayed directly on the monitor, supporting organized documentation during procedures.

• Patient information: Patient ID, name, sex, age, date of birth and recording date can be displayed.
• Comments: Procedure-related comments can be displayed on the monitor.
• Patient registration: Up to 50 patient data sets can be registered.
• Recording status: The status of portable memory, DVR, video printer and image filing systems can be displayed.
• Image information: Enhancement level, zoom ratio, colour mode and focus information can be displayed.
• Portable memory: Compatible with Olympus MAJ-1925 media.
• Recording formats: Supports uncompressed TIFF and JPEG compression at approximately 1/5 and 1/10.
• Recording capacity: Approximately 227 TIFF images, 1,024 JPEG 1/5 images or 2,048 JPEG 1/10 images can be recorded.
• User settings: Up to 20 user settings can be registered and selected settings can remain stored after shutdown.

CLV-190 Xenon Light Source

The Olympus CLV-190 is a xenon illumination system designed to provide stable and adjustable lighting for endoscopic observation. Its automatic brightness adjustment system helps maintain appropriate illumination according to the connected scope and observation conditions.

• Light source: 300 W ozone-free xenon short-arc lamp.
• Lamp life: Approximately 500 hours of continuous use; actual life may vary with intermittent operation.
• Brightness control: Light intensity is controlled through a light-path diaphragm.
• Automatic brightness adjustment: Servo-diaphragm technology automatically adjusts illumination.
• Automatic exposure: Provides 17 exposure steps.
• Intensity modes: Normal and high-intensity modes are available.
• NBI illumination: Supports NBI observation.
• Colour conversion: Possible using a dedicated filter.
• Cooling: Forced-air cooling system.
• Emergency lamp: Integrated 12 V, 35 W halogen emergency lamp.
• Emergency lamp life: Approximately 500 hours.
• Air supply: Diaphragm-type pump with four pressure settings: OFF, low, medium and high.
• Water supply: Water is supplied by pressurizing a detachable water container with air.

One-Touch Endoscope Connection

The EVIS EXERA III system features a newly designed waterproof one-touch connector. This enables a one-step connection between the compatible endoscope and light source and eliminates the need for a separate scope cable for connection to the video processor.

System Integration

The CV-190 is designed for compatibility with a broad range of Olympus endoscope platforms, including EVIS 100/130/140/150, EVIS EXERA 160, EVIS EXERA II 180, EVIS EXERA III 190 and GI/BF/VISERA series scopes, according to the manufacturer's documentation.

• Peripheral integration: Link connections help reduce complicated cable arrangements.
• Documentation system: Supports integration with the OLYMPUS documentation system.
• Endoscope remote switches: Functions assigned to compatible endoscope remote switches can be configured through user settings.
• Memory: Selected image-processing settings can be retained even after the video system is switched off.

Operational Convenience

The EVIS EXERA III CV-190/CLV-190 combination is designed to streamline endoscopic workflows through automatic illumination, configurable image processing, pre-freeze image selection, simplified one-touch connections and integration with peripheral documentation equipment. Its combination of advanced visualization functions and flexible connectivity makes it suitable for a wide range of compatible Olympus endoscopic applications.
