Olympus service division investigated the subject device.At the inspection of angulation, deterioration of angulation range was confirmed and it was determined that it needs repair.At the whole visual inspection, scratches and crashing of the light guide tube, and damage of the angulation control lever were confirmed.They were determined that they need repair.Scratches on the video connector, smear on the control section and the grip cover were also confirmed but they were within the specification.At the inspection of outer view of the insertion portion, a pinhole on the angulation rubber, a chipping of the adhesive on the angulation rubber, and peeling-off of the coating on the universal cord were confirmed and they were determined that they need repair.At the inspection of outer view of the distal end, cracking of the light guide lens was confirmed and it was determined that it needs repair.At the inspection of insertion performance of an instrument and brush, the instrument was confirmed to be caught in the subject device, and the subject device was determined that it needs repair.At the water leak test, air leak form the angulation rubber was confirmed and it was determined that it needs repair.The exact cause of the phenomenon could not be determined at this time.The possibility cannot be ruled out that it was caused by an insufficient reprocessing associated with the condition of the device such as a pinhole on the angulation rubber and cracking on the light guide lens etc.Please cross reference the following mdr report number#: 8010047-2016-01319.
