Additional Manufacturer Narrative
This supplemental report is being submitted to provide the results of the final investigation.Updated fields: d4 (expiration), d9, h3, h4, h6.The device was returned to olympus for inspection and the reported failure was confirmed.The probe broke off 9 mm from the distal end.A root cause could not be identified.Based on the results of the investigation, it is likely the following mechanism led to the malfunction: during the output activation, the probe was contacting hard tissue, metal objects or surgical instruments.Due to ultrasonic vibration, scratches were generated.A force to activate the output, or a force to grasp the tissue was applied to the probe.Therefore, cracks were generated at the scratched area.A load was applied to the probe, causing it to break off.A review of the device history record found no deviations that could have caused or contributed to the reported issue.Should additional relevant information become available, a supplemental report will be submitted.Olympus will continue to monitor field performance for this device.
