Olympus GIF-Q160Z

The GIF-Q160Z is used for upper gastrointestinal endoscopy. An examination follows the oesophagus into the stomach and on to the duodenum, and the 10.5 to 10.9 mm tube and 1,030 mm working length are the dimensions that carry the scope along that route. The team watches each stage live, so they see the lining change as the tip advances.

Endoscopists begin in the WIDE position, where the 140° forward view surveys the lining. Angulation controls bring each area to the centre of the picture, and a move to TELE narrows the field to 75° so a chosen area of the surface fills more of the screen. Surface pattern and fine lining detail then sit in view long enough to be read. Nurses and assistants watch the same screen, keeping the whole room in one image.

Hospital endoscopy suites, gastroenterology departments and day-case units are its settings. It connects to a CV-160 video processor and displays the image on the attached screen. Each patient on a list is examined in turn, and the reusable scope returns to service after reprocessing between patients.

Typical sessions cover diagnostic examination of the upper tract. The 2.8 mm channel carries suction and accessories when a closer action is needed, and the 210° upward bend lets the operator turn the tip back to view the area just passed. A survey and a close look therefore share one insertion. Bending 90° down and 100° to each side aims the tip at either wall of the lumen as the examination advances.

Survey and close inspection in one insertion

Optical zoom moves the picture from a 140° WIDE field to a 75° TELE field without changing scope. The operator surveys the upper tract, then closes in on a chosen area and returns to the survey. One insertion carries the whole examination.

A 140° WIDE field for surveying

In the WIDE position, the forward view takes in a 140° field. The lining beside the tip and the lumen ahead appear in one frame, so the operator reads a large area at a glance while the tip advances.

A 75° TELE field for a closer look

TELE narrows the field to 75°, so a chosen area fills more of the screen. Surface pattern and lining detail become easier to read, and the team watches the same enlarged picture together.

Four-way bending with 210° upward travel.l

Travel reaches 210° upward, 90° downward and 100° to each side. The upward range turns the tip back to look at the area just passed, and the side travel aims the tip at either wall of the lumen.

A 2.8 mm channel for suction and accessories

The 2.8 mm instrument channel runs from the control head to the tip. It carries suction to clear the field and passes accessories to the tip when closer action is needed. A single channel serves both jobs.

Dimensions that reach the duodenum

A tube between 10.5 and 10.9 mm across, with a working length of 1,030 mm, carries the scope through the oesophagus and stomach to the duodenum. Every patient on a list is examined with the same diameter and the same reach, so the routine stays familiar to the team.

One processor in the EVIS EXERA chain

The scope works with the CV-160 video processor, which feeds the screen. The scope, processor, and screen form one chain, so the picture arrives on the screen as the tip sees it. The room's display then carries the whole examination.

A reusable scope that returns to the list

The GIF-Q160Z is a reusable endoscope. After reprocessing between patients, it returns to service, so one scope can cover a series of examinations on a single list.

Video image at the tip

A video gastroscope sends a live image to the screen. Whoever is steering and whoever is assisting watch the same image.

Optical zoom

Optical zoom changes the view between a WIDE position and a TELE position at the tip. The scope stays where it is, and the picture changes its field and its enlargement.

140° WIDE field of view

In the WIDE position, the field of view is 140°. The lining beside the tip and the lumen ahead appear in one frame, and the operator reads both while holding the tip still.

75° TELE field of view

In the TELE position, the field narrows to 75°. A chosen area then fills more of the screen, which brings surface pattern into closer view.

Forward direction of view

The view is forward, straight along the axis of the tube, so the tip faces what the operator is looking at. Steering the tip moves the area on show.

10.5 to 10.9 mm insertion tube

Tube diameter lies between 10.5 and 10.9 mm along the working length. This figure governs how the tube passes through the oesophagus and stomach on its way to the duodenum.

1,030 mm working length

Working length is 1,030 mm: the section that enters the patient. Its reach extends the tip to the duodenum.

1,350 mm total length

The 1,350 mm total length covers the scope from the tip to the connector end, with 1,030 mm of working length.

2.8 mm instrument channel

A 2.8 mm channel links the control head to the tip. Suction and accessories pass through it, and the opening is within the operator's reach.

Upward bending to 210°

Upward travel of 210° takes the tip past a half circle so that the operator can look back along the route just taken.

Downward bending to 90°

Down travel reaches 90°. Used with the other three directions, it lets the tip follow the curve of the lumen toward the area under examination.

Right and left bending of 100°

Each side reaches 100°. Together with up and down, the operator controls four directions so that the tip can aim at either wall.

EVIS EXERA system and CV-160 processor

The scope is part of the EVIS EXERA system. The CV-160 video processor receives the signal at the video connector and presents the picture on the screen.

FDA 510(k) clearance K011151

The scope is listed under FDA 510(k) number K011151 as a Class II gastroscope with product code FDS. This model name is listed under this clearance.

The GIF-Q160Z suits endoscopy teams that want to survey the upper digestive tract and then closely examine a chosen area in the same examination. Its strength is optical zoom: a 140° WIDE view for the survey, a 75° TELE view for the close look and four-way bending that reaches 210° upward to aim the tip. Teams that work through a list of patients, moving from the oesophagus to the stomach and the duodenum, keep one picture and one insertion throughout. A forward view, a 10.5 to 10.9 mm tube, and a CV-160 pairing fit regular upper tract lists in a hospital endoscopy suite. The 2.8 mm channel carries suction and accessories, and the 1,030 mm working length completes the reach.
