Investigation: the investigation was carried out visually and a functional test was performed.The connectin pins are no longer according to the specifications, since they are deformed, most likely caused by a drop.Due to these damages, a proper mounting of the disposable tube set fk888su can no longer be guaranteed.The functional test was carried out successfully, but the set could only be assembled with high forces.Without a correct connection of the tube set, the function of the kairison bone punch will not be according to specification.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 probably related to an insufficient usage.No capa is necessary.
