Gastroscope

Flexible Gastroscope for Upper Gastrointestinal Endoscopy

The Brightfield Flexible Gastroscope is designed for diagnostic examination of the esophagus, stomach and duodenum, as well as selected therapeutic endoscopic procedures. Its optical characteristics, flexible insertion tube and working channel allow physicians to examine gastrointestinal structures and perform endoscopic manipulations under visual guidance.

A 120° field of view, a 3–100 mm depth of field and a 2.8 mm working channel are the main features of this gastroscope. These specifications are important for mucosal examination, navigation within the upper digestive tract and the use of compatible endoscopic instruments.

120° Field of View for Examination of the Upper GI Tract

The 120° viewing angle allows the physician to observe a broad area of the gastrointestinal tract through the endoscope’s optical system.

This is particularly useful when examining the walls of the esophagus, stomach and duodenum, where the physician needs to assess the mucosal surface, identify visible abnormalities and inspect anatomical structures from different positions.

Clear Visualization at Distances from 3 to 100 mm

The gastroscope has a depth of field ranging from 3 to 100 mm, allowing structures to be viewed at both close and greater distances from the distal tip.

At shorter distances, the physician can examine selected areas of the mucosa in more detail. At greater distances, the optical system allows observation of a wider anatomical area, helping the physician maintain orientation during the examination.

This viewing range is useful when alternating between general inspection of the gastrointestinal tract and closer assessment of specific mucosal changes.

9.2 mm Flexible Insertion Tube

The gastroscope is equipped with a 9.2 mm insertion tube designed to follow the natural curves of the upper gastrointestinal tract.

The flexible construction and steerable distal section allow the physician to adjust the viewing direction while advancing and positioning the instrument.

This maneuverability is important when passing through anatomical bends and examining different areas of the stomach and duodenum.

2.8 mm Working Channel for Diagnostic and Therapeutic Procedures

The 2.8 mm working channel allows compatible endoscopic instruments to be introduced during examination.

In addition to visual inspection, the channel enables selected diagnostic and therapeutic manipulations under direct endoscopic guidance.

The working channel diameter should be considered when selecting accessories. Instruments must be compatible with the gastroscope and suitable for the intended procedure.

1300 mm Total Length

The gastroscope has a total instrument length of 1300 mm. This parameter should be considered when selecting the endoscope for use with the department’s examination equipment and accessories.

The total length should not be confused with the working length of the insertion tube, which is a separate technical parameter.

Clinical Applications

The Brightfield Flexible Gastroscope is suitable for upper gastrointestinal endoscopy in gastroenterology departments, endoscopy units and medical facilities performing diagnostic and therapeutic examinations.

• Esophagoscopy: Examination of the esophagus and assessment of visible mucosal changes.
• Gastroscopy: Inspection of the gastric mucosa and anatomical structures of the stomach.
• Duodenoscopy: Endoscopic examination of accessible areas of the duodenum.
• Targeted examination: Closer visual assessment of suspicious areas identified during the procedure.
• Endoscopic interventions: Selected diagnostic and therapeutic manipulations using instruments compatible with the 2.8 mm working channel.

The combination of a wide field of view, extended depth of field and an instrument channel makes the gastroscope suitable for routine upper gastrointestinal examinations and procedures requiring additional endoscopic manipulation.
