The COLONOVIDEOSCOPE OLYMPUS CF-EZ1500DL & CF-EZ1500DI are intended to be used with a video system center, endoscope position detecting unit, documentation equipment, monitor, endoscopic therapy accessories (such as a biopsy forceps), and other ancillary equipment for endoscopy and endoscopic surgery. The COLONOVIDEOSCOPE OLYMPUS CF-EZ1500DL/I are indicated for use within the lower digestive tract (including the anus, rectum, sigmoid colon, colon, and ileocecal valve). The GASTROINTESTINAL VIDEOSCOPE OLYMPUS GIF-EZ1500 is intended to be used with a video system center, documentation equipment, monitor, endoscopic therapy accessories (such as a biopsy forceps), and other ancillary equipment for endoscopy and endoscopic surgery. The GASTROINTESTINAL VIDEOSCOPE OLYMPUS GIF-EZ1500 is indicated for use within the upper digestive tract (including the esophagus, stomach, and duodenum).
Device Description
The endoscope consists of three parts: the control section, the insertion section, and the connector section. 1) Control section: The UP/DOWN angulation control knob and the RIGHT/LEFT angulation control knob on the control section are connected to the tip of the bending section by a series of wires. By operating the angulation control knobs, the bending section at the distal end bends vertically or parallel to guide the distal end for insertion and observation. The observation mode can be selected by focus switching function, "near focus mode" featuring innovative resolving power for close observation or "normal focus mode" for normal observation. To realize the dual focus mechanism, Voice Coil Motor (VCM) is incorporated as an actuator. The endoscope contains a cylinder to attach a suction valve for suction and air/water valve. Depressing the suction valve will allow the physician to use the endoscope to suction any fluids which are obscuring a good view of the tissue. Therapeutic instruments can be passed through the instrument channel for performing endoscopic biopsy and other therapies. Depressing the air/water valve will allow the doctor to feed water through the endoscope for lens washing. It also can be operated to feed air for removing any fluids or debris adhering to the objective lens. 2) Insertion section: The insertion section has main parts including the image guide, light guides that bring light from the video system center through the endoscope, and instrument channel where therapeutic tools can be pushed in and out (also the suction channel). 3) Connector section: The connector section connects the endoscope with the video system center (CV-1500) through the universal cord.

• Principle of Operation

The endoscope consists of three parts: the control section, the insertion section, and the connector section. The basic principle including user interface and operation for the procedure of the endoscope is identical to that of the predicate device.

1) Control section

The UP/DOWN angulation control knob and the RIGHT/LEFT angulation control knob on the control section is connected to the tip of the bending section by a series of wires. By operating the UP/DOWN angulation control knob and the RIGHT/LEFT angulation control knob, the bending section at the distal end bends vertically or parallel to guide the distal end for insertion and observation.

The observation mode can be selected by focus switching function, "near focus mode" featuring innovative resolving power for close observation or "normal focus mode" for normal observation. To realize the dual focus mechanism, Voice Coil Motor (VCM) is incorporated as an actuator.

The endoscope contains a cylinder to attach a suction valve for suction and air/water valve. Depressing the suction valve will allow the physician to use the endoscope to suction any fluids which are obscuring a good view of the tissue. Therapeutic instruments can be passed through the instrument channel for performing endoscopic biopsy and other therapies. Depressing the air/water valve will allow the doctor to feed water through the endoscope for lens washing. It also can be operated to feed air for removing any fluids or debris adhering to the objective lens.

2) Insertion section

The insertion section has main parts including the image guide, light guides that bring light from the video system center through the endoscope, and instrument channel where therapeutic tools can be pushed in and out (also the suction channel).

3) Connector section

The connector section connects the endoscope with the video system center (CV-1500) through the universal cord.
