GIF-HQ290: Advanced Visualization for Upper Gastrointestinal Endoscopy
The Olympus GIF-HQ290 is a high-performance upper GI endoscope, central to the EVIS LUCERA ELITE system. It sets a new benchmark in the field of gastrointestinal endoscopy by combining outstanding image quality, mechanical precision, and innovative features to meet the demands of modern clinical practice. Tailored for the examination of the upper gastrointestinal tract, the GIF-HQ290 enables detailed visualization of the mucosa, supporting efficient detection, diagnosis, and treatment of a wide range of GI conditions.
One of its standout innovations is the Dual Focus technology, which allows the endoscopist to easily switch between near and normal focus modes at the touch of a button. This capability enables the practitioner to optimize depth of field in real time—whether for general overviews or for close-up inspection of mucosal surfaces—enhancing diagnostic confidence and visual clarity.
Image resolution is significantly enhanced by a newly developed optical system that works in tandem with the CV-290 video processor and CLV-290/CLV-290SL light sources. This combination delivers superior image sharpness, enabling clinicians to detect even subtle lesions and conduct therapeutic procedures with greater precision.
The next-generation NBI (Narrow Band Imaging) technology incorporated in the GIF-HQ290 offers double the visible distance compared to its predecessor. This leap in performance broadens the scope of clinical applications, especially in the assessment of mucosal and vascular patterns, reaffirming NBI's status as a gold standard for endoscopic imaging in gastroenterology.
The scope’s forward water jet function ensures a consistently clear field of view by removing debris and mucus during observation or therapeutic procedures. This integrated irrigation channel, along with an air/water nozzle, also helps maintain lens clarity throughout the examination.
The GIF-HQ290 is designed with a fully submersible one-touch connector, which not only streamlines scope setup and reprocessing but also eliminates the need for a separate waterproof cap. This reduces the risk of costly repairs due to accidental immersion and improves workflow efficiency.
The insertion tube’s ergonomic design, with an outer diameter of only 9.9 mm and a wide angulation range (up to 210° upward), provides superior maneuverability through the GI tract. Its 2.8 mm working channel accommodates a wide variety of endoscopic tools, enabling seamless diagnostic and therapeutic interventions.
With its high-definition optics, ergonomic design, waterproof safety, and intuitive controls, the GIF-HQ290 is a premium instrument tailored for comprehensive and effective upper GI endoscopy. It brings together the essential elements of image excellence, user convenience, and clinical reliability.
