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

Olympus EVIS EXERA III System (CV-190 / CLV-190)

The EVIS EXERA III system represents the third generation of Olympus's diagnostic and therapeutic endoscopy line. It pairs an advanced HDTV video processor, the CV-190, with a dedicated xenon light source, the CLV-190, to deliver high-quality diagnostic imaging, enhanced vascular contrast, and access to a wide range of cutting-edge endoscope technologies. Olympus positions this system as a way to revolutionize clinical workflow while also extending the value of an existing endoscope inventory.

Components

• Olympus CV-190 video processor — includes advanced features such as Narrow Band Imaging (NBI) for increased contrast between blood vessels and mucosa, a Pre-Freeze function that automatically selects the clearest still image from those captured just before the freeze command, and a Picture-in-Picture mode that improves observation by displaying multiple views simultaneously. The processor also handles dual focus imaging (near focus / normal focus) with compatible HQ scopes, along with HD-SDI, SD-SDI, DVI, and DV outputs.
• Olympus CLV-190 xenon light source — a 300 W ozone-free short-arc xenon lamp offering automatic light intensity adjustment for ideal illumination tailored to each scope. It also features a waterproof one-touch connector that eliminates the need for a separate scope cable, along with a redesigned fan that considerably reduces operating noise in the room.
• Compatible Olympus EVIS EXERA III scopes — the system accepts 190 series scopes while remaining compatible with the EVIS 100/130/140/150, EVIS EXERA 160, and EVIS EXERA II 180 series, as well as GI/BF/VISERA range scopes — protecting a facility's investment in its existing scope inventory.
• Control keyboard, video cables, and fiber optics — the keyboard enables patient data entry and display (ID, name, sex, age, date of birth, comments), along with control of image settings (white balance, color tone, contrast, iris mode, enhancement level). Video cables and fiber optics ensure reliable transmission of the light and video signal between the scope, light source, and processor.
• High-resolution medical monitor — displays the endoscopic image in 16:9 or 16:10 HDTV-compatible format, with analog or digital outputs (RGB, YPbPr, HD-SDI, DVI), for precise real-time observation of examined tissue.

Advanced imaging features

According to the brochure, NBI on the EVIS EXERA III 190 series provides twice the viewable distance compared to the previous EVIS EXERA II 180 series, thanks to an improved lamp design and more powerful signal processing. This translates into markedly better contrast between blood vessels and mucosa, making it easier to detect subtle lesions during examination.

The dual focus function, available with compatible HQ scopes, allows switching between a near-focus view and a normal-focus view, giving an optimal view depending on the nature of the observation. The CV-190 processor's improved image processing also delivers more faithful color reproduction, minimized image noise, and reduced halation.

Connectivity and data management

The CV-190 system supports portable memory for standard data management (via MAJ-1925 media), as well as connection to peripheral equipment such as a monitor, video recorder, video printer, or image filing system. The Olympus documentation system enhances networking capability, and DV output supports compatibility with suitable documentation devices. Up to 50 patient data sets can be pre-registered, streamlining exam preparation.

Ergonomics and reliability

The CLV-190's waterproof one-touch connector simplifies scope setup and reduces handling when switching scopes. The noise reduction achieved through the redesigned fan contributes to a more comfortable room environment for the care team. User settings, except for the filter setting, are retained in memory even when the light source is switched off, simplifying the transition between examinations.
