Device evaluation found a cut on a-rubber and due to cut watertigntess is lost ( leakage was noted).In addition, as stated in section b5, the device biopsy channel was found shaved, scraped.Additional findings unrelated to the reportable event were noted below: adhesive on a-rubber is detached.Connecting tube has a dent.Due to wear of angle wire, bending angle in up/down direction does not meet the standard value.Channel shaft has a foreign material.Control unit sticky.Scratch noted on ud plate, control unit, angulation lever , eyepiece, universal cord and s- cover.A review of the device history record found the subject device was shipped in accordance with specifications.Repair history review found the subject device has never been repaired.The root cause of the reported phenomenon could not be conclusively specify, however, it was presumed that biopsy port was scraped due to rubbing of coil sheath of cleaning brush.Grounds for presumption are as follows: - since biopsy valve is attached during procedure, forceps is unlikely to rub against biopsy port.-since biopsy valve is detached during reprocessing, coil sheath of cleaning brush may rub.Instruction for use (operation manual_ preparation and inspection_ inspection of the endoscope) states : inspect the external surface of the entire insertion tube including the bending section and the distal end for dents, bulges, swelling, peeling, scratching, holes, sagging, transformation, bends, adhesion of foreign body, dropout of parts, any protruding objects or other irregularities.Olympus will continue to monitor complaints for this device.Supplemental report(s) will be submitted should any relevant new information is available.
