This instrument has been designed to be used with a video system center, light source, documentation equipment, monitor, hand instruments, electrosurgical unit and other ancillary equipment for endoscopic diagnosis and treatment within the abdomen and thoracic cavities including the female reproductive organs.
Device Description
The HD EndoEYE - High Definition Digital Video Laparoscope is a video endoscope used for endoscopy The HD Lhoon is "Thigh Dominal cavities which is basically identical to the predicate device, OES Laparo- Thoraco Videoscope, for the same application areas.
The major difference from the predicate device is only the NBI function added to the subject device.
When the CLV-180 and CV-180 or the OTV-S7Pro and CLV-S40Pro are combined with HD EndoEYE, both an endoscopic image by white light illumination and that by NBI illumination can be observed within the thoracic and abdominal cavities. The CV-180 identifies when an NBI-compatible scope is connected, by using the Scope ID function provided with the scopes.
