Olympus GIF-HQ190 Gastrointestinal Videoscope

Advanced High-Definition Imaging for Upper GI Excellence

The Olympus GIF-HQ190 is a premium high-definition gastrointestinal videoscope engineered to deliver exceptional visualization, precision diagnostics, and procedural efficiency in upper gastrointestinal endoscopy. As part of the EVIS EXERA III 190 Series platform, this state-of-the-art gastroscope integrates advanced optical technology, enhanced imaging capabilities, and ergonomic innovations to support clinicians in detecting, characterizing, and managing upper GI pathologies with confidence.

Developed to meet the increasing demand for early detection and accurate mucosal assessment, the GIF-HQ190 combines optical clarity, imaging contrast enhancement, and practical workflow improvements into a single, versatile instrument. It represents Olympus’ commitment to advancing endoscopic imaging standards and improving patient outcomes in modern gastroenterology practices  .

Exceptional Image Quality for Confident Diagnosis

At the core of the GIF-HQ190 is an advanced high-performance CCD sensor designed to deliver outstanding image clarity. The enhanced imaging system provides:

• Brighter illumination across the entire field of view
• Improved contrast for clearer differentiation of mucosal structures
• Reduced image noise
• Reduced halation (glare from reflective surfaces)
• High-definition performance even during electronic magnification

These imaging improvements are particularly important during detailed mucosal inspection, where subtle color variations, surface irregularities, and vascular changes may indicate early neoplastic transformation or inflammatory disease. The improved contrast and brightness allow endoscopists to detect fine abnormalities that may not be easily visible with conventional systems.

Electronic zoom maintains image integrity, ensuring that magnified views preserve structural detail without compromising clarity. This capability supports careful inspection during screening, surveillance, and therapeutic procedures.

Dual Focus Technology: Precision at the Push of a Button

One of the defining features of the GIF-HQ190 is Olympus’ innovative Dual Focus technology. This optical advancement allows the operator to instantly switch between two focal settings during the procedure using a simple button on the scope handle.

Normal Focus Mode

• Depth of field: 5–100 mm
• Ideal for general inspection and broad visualization of anatomical structures

Near Focus Mode

• Depth of field: 2–6 mm
• Optimized for close-up observation of mucosal patterns and microvascular architecture

This seamless transition between focal depths enhances diagnostic flexibility. During routine inspection, clinicians can survey the broader anatomical landscape in normal focus mode. When a suspicious lesion or subtle abnormality is identified, near focus mode enables close evaluation without the need to change instruments or reposition significantly.

Dual Focus improves workflow efficiency and supports more confident optical diagnosis by allowing targeted, high-resolution examination of areas of interest.

Narrow Band Imaging (NBI): Enhanced Visualization of Mucosal and Vascular Patterns

The GIF-HQ190 integrates Narrow Band Imaging (NBI), an advanced optical image enhancement technology designed to improve the visualization of mucosal surface structures and vascular patterns.

In the EVIS EXERA III 190 Series platform, NBI provides:

• Significantly brighter NBI images
• Twice the viewable distance compared to previous-generation 180 Series scopes
• Improved contrast for enhanced mucosal pattern recognition

NBI uses specific light wavelengths that penetrate superficial mucosal layers and emphasize capillary networks and submucosal vessels. This enhanced contrast aids in:

• Characterizing mucosal morphology
• Assessing vascular patterns
• Evaluating suspected dysplasia or early carcinoma
• Supporting surveillance in conditions such as Barrett’s esophagus

High-definition NBI allows for more detailed observation and may reduce the need for unnecessary biopsies when optical diagnosis is sufficient. The improved brightness compared to earlier systems ensures that image quality remains high even when examining larger luminal areas.

Forward Water Jet Function: Clear Visualization Throughout the Procedure

Maintaining a clear visual field is critical during upper GI endoscopy. The GIF-HQ190 includes a standard forward water jet function, allowing the operator to quickly flush away mucus, blood, or debris.

Benefits include:

• Immediate clearing of the mucosal surface
• Reduced need for accessory instruments for irrigation
• Improved visualization during both diagnostic and therapeutic procedures

By preserving image clarity throughout the procedure, the forward water jet supports accurate lesion detection and reduces interruptions during examination.

Waterproof One-Touch Connector: Improved Workflow and Safety

The GIF-HQ190 features a redesigned waterproof one-touch connector, engineered to simplify setup and enhance durability.

Key advantages include:

• Reduced effort during pre-procedure setup
• Faster turnover between cases
• Fully submersible design
• Elimination of the need for a separate water-resistant cap
• Reduced risk of damage from accidental immersion

This connector design streamlines reprocessing workflows and enhances operational efficiency in busy endoscopy units. By minimizing the steps required to prepare the scope for use and cleaning, facilities can improve productivity while maintaining high safety standards.

Ergonomic Design for Clinical Efficiency

The GIF-HQ190 is designed with operator comfort and procedural control in mind. Its lightweight construction and intuitive control layout allow for precise maneuverability and reduced hand fatigue during longer procedures.

Angulation Capabilities

• Up: 210°
• Down: 90°
• Right: 100°
• Left: 100°

The generous angulation range supports thorough visualization of difficult-to-access anatomical areas, including retroflexed views in the stomach. Smooth, responsive control enhances procedural confidence and contributes to comprehensive examination.
