Olympus GIF-N180

The GIF-N180 serves endoscopy units, outpatient clinics and hospital gastroenterology departments that examine the upper digestive tract. Its 4.9 mm tube is sized for entry through the nose, and the mouth is the second route, so one scope covers both approaches.

Gastroenterologists and endoscopy nurses use it to diagnose the oesophagus and stomach. The 120° forward view and the 3 to 100 mm depth of field let the operator inspect the mucosa close up and then take in the wider scene without changing scope. A 210° upward bend and a 90° to 120° downward bend direct the tip along the tract, and the distal nozzle rinses the lens whenever the picture needs clearing.

Units that run unsedated examinations value a slim tube because the person stays awake and the nasal passage is narrow. The video picture appears on the monitor throughout insertion, so the operator follows the passage ahead as the tube advances. The 2.0 mm channel accepts accessories, so sampling or treatment can follow the inspection within the same insertion. Narrow band imaging adds a filtered-light view on compatible EVIS 180 series systems, which brings out surface and vessel detail in the mucosa.

Departments that keep several scopes in rotation use Scope ID, which shows each scope's stored information on the monitor and supports suite management. Compatibility with the CV-140, CV-160, CV-180 and CV-190 video processors lets the GIF-N180 join a system already in the room. The ergonomic grip, angulation knobs, and user-selectable switches keep the main functions within the operator's reach throughout a long list of examinations.

A tube sized for the nasal passage

At 4.9 mm, the insertion tube and distal end are narrow enough to enter through the nose. The examination can then run with the person awake, which suits units that offer unsedated upper digestive tract examination.

One scope for the nose and the mouth

Nasal and oral insertion both use the same scope, controls, and image. A unit that offers both routes needs a single instrument.

A wide view inside a narrow tube

The 120° forward view arrives through a tube that measures 4.9 mm. The operator sees a broad area ahead of the tip while the tube stays slim enough for the nose.

A lens that clears in place

The distal irrigation nozzle rinses the lens at the tip. The scope stays in place during rinsing, so the examination stays in position along the tract.

A channel for accessories

The 2.0 mm instrument channel carries accessories to the tip. Sampling or treatment can follow the inspection in the same insertion.

Controls within reach

An ergonomic grip, easy-to-reach knobs and user-selectable switches place the main functions under the operator's hand. The layout supports handling during long examinations.

Scope information on the monitor 

Scope ID stores the scope's information in a memory chip and displays it on the monitor. Units that manage several scopes gain a clear record of which instrument is connected.

Four video processors

The CV-140, CV-160, CV-180 and CV-190 processors all work with the GIF-N180. A suite built around any of them can add the scope.

Narrow band imaging on compatible systems

Narrow band imaging runs on compatible EVIS 180 series systems. The filtered-light mode emphasises mucosal surface and vessel patterns during the examination.

4.9 mm insertion tube

The insertion tube measures 4.9 mm in outer diameter. This slim width enables nasal insertion and carries the channel, optics, and bending section along the working length.

4.9 mm distal end

The distal end also measures 4.9 mm, which gives the tip the same profile as the tube behind it. The lens and the nozzle sit at this end.

2.0 mm instrument channel

The channel has an inner diameter of 2.0 mm. Accessories enter at the control head and reach the tip, so viewing and handling share one insertion.

1,100 mm working length

The 1,100 mm working length balances stiffness and ease of insertion. The balance keeps the tube controllable as it advances along the tract.

1,420 mm total length

Overall, the scope measures 1,420 mm. The figure helps with trolley and storage planning for the complete instrument.

120° forward field of view

The lens looks straight ahead across 120°. A forward view matches the direction of travel, so the way ahead stays in sight as the tip advances.

Depth of field from 3 to 100 mm

Focus holds across 3 to 100 mm. Near surfaces and far ones both stay in view during a single examination.

2 mm minimum visible distance

The closest visible point lies 2 mm from the distal end. Inspect tissue right at the tip at close range.

210° upward bending

The tip bends 210° upward. The range sweeps the forward view upward from the straight position through a wide arc.

Downward bending of 90° to 120°

Downward bending runs between 90° and 120°. Together with the upward range, it steers the tip along the curves of the tract in one plane.

Distal irrigation nozzle

A nozzle at the tip directs irrigation across the lens. The view stays clear, and the scope holds its position.

Ergonomic grip and angulation knobs

The grip is shaped to fit the operator's hand, and the angulation knobs are within easy reach.

User-selectable switches

The user can assign the switches on the control head. Frequently used functions then sit within fingertip reach.

Scope ID memory chip

A built-in memory chip stores the scope's information. The connected system displays it on the monitor, helping manage the endoscopy suite.

Video processor compatibility

The scope works with the CV-140, CV-160, CV-180 and CV-190 video processors. It belongs to the EVIS EXERA II family, so the surrounding system follows that platform.

Narrow band imaging compatibility

Narrow band imaging runs on compatible EVIS 180 series systems. Compatible systems supply the light mode, and the 120° forward view carries it.

The GIF-N180 suits endoscopy units that examine the upper digestive tract and require nasal and oral insertion through a single instrument. Its strength is its 4.9 mm tube: the scope enters through the nose, provides a 120° forward view, includes a 2.0 mm instrument channel and a distal nozzle, and steers with 210° of upward bending. Units that value unsedated examination are the natural match, and suites that run the CV-140, CV-160, CV-180 or CV-190 processors can add it directly. Scope ID keeps each instrument identified on the monitor, which suits departments that manage several scopes, and narrow band imaging adds a second light mode on compatible EVIS 180 series systems. Its 1,100 mm working length reaches into the upper digestive tract.
