Manufacturing evaluation: investigation: the instrument was available for investigation decontaminated.The instrument is in a used condition.Both blades are crushed, deformed, and no longer even.The blades are crushed but not fractured.The original labelling was taped and the surface was sandblasted.Based on the taped surface and foreign labelling, we assume that a third party carried out maintenance.The uneven blades are caused by tumbling components, caused by the loosened nuts.In addition, one of the nuts is missing.Batch history review: the device quality and manufacturing history records have been checked for the available lot number and found to be according to our specifications valid at the time of production.No similar incidents have been filed with products from this batch.Conclusion and root cause: based on the information available as well as a result of our investigation the root cause of the failure is most likely related to third party maintenance or improper reprocessing.Rationale: there is the possibility that during this maintenance the nuts have not been tightened according to the aesculap specifications valid at the time of production; therefore, a tumbling of the components and a release of the nuts cannot be excluded.Another possibility is that the instrument has been dismantled for reprocessing, and have not been tightened accordingly.The tumbling of the components is most likely also the reason for the damaged blades, since a proper cutting performance is no longer possible.Furthermore, after each reprocessing the instrument needs to undergo an inspection for loosened or damaged components.No capa required.
