Manufacturing site evaluation: due to the clarifcation,the report was reassessed and found to no longer require submission - no mulfunction or serious injury.Manufacturing side evaluation: we received a complaint about an intraoperatively broken suction instrument.Statement of the customer.During the first insertion, the tip was damaged, broke off.The instrument arrived with the broken off part in a decontaminated condition and it is available for investigation.Consequences for the patient: unknown.Information has been requested at the clinic at least three times.Investigation: the instrument arrived in a clean status with the broken off tube gf351203.The investigation was carried out visually and microscopically with the digital microscope vhx-5000 keyence (eq.-nr.2000024840) and the digital-camera "panasonic dmc tz8".We made a visual inspection of the instrument.Here we found a bent and deformed mandrin.We also detected a bent and deformed tube gf351203.Additionally we discovered an unknown labeling.Furthermore we found cracks and brown discolorations.Batch history review: the device history records (dhr) have been checked for the available lot number(s) and found to be according to the specification, valid at the time of production.There is no indication for a manufacturing error or a material failure.One similar incident have been filed with a product from the same lot number.Conclusion and root cause: the failure is most probably usage related.Rationale: according to the quality standard and dhr files, a material defect and production error can be excluded.Investigations lead to the assumption that the broken off tube was caused by an improper handling due to a mechanical overload situation.The bent and deformed tube is an additional sign for a mechanical overload situation.It could be that the brown discoloration is rust.The cause for the unknown labeling could not be determined.Corrective action: according to sop sa-de13-m-4-2-04-000-0 (corrective action and preventive action), a capa is not necessary.
