This report is being supplemented to provide additional information based on the legal manufacturer's final investigation.A review of the device history record found no deviations that could have caused or contributed to the reported issue.Based on the results of the investigation, the root cause of the event was unable to be identified.The foreign material was unable to be identified.The actual product is cleaned, disinfected, and sterilized before being sent to olympus, and the reprocessing method does not deviate significantly from the instruction manual.There was no equipment abnormality near the forceps stand (wire), which is the location where foreign matter was attached.Additionally, the adhesive peeling and the acoustic lens damage likely occurred due to a physical stress by dropping and/or knocking the affected part to a hard surface/object and applying a chemical stress during the cleaning/sanitization.The event can be detected/prevented by following the instructions for use which are described in the following chapters: chapter 6 application and conditions of cleaning, disinfection, and sterilization and chapter 7 cleaning, disinfection, and sterilization procedures.Olympus will continue to monitor field performance for this device.
