The reported event that set screwdriver, flexible shaft gamma3® 4 mm was alleged of issue (cleanability at customer) could not be confirmed, since the device was not returned for evaluation and no other evidences were provided.A review of the device history for the reported lot did not indicate any abnormalities.No corrective actions are required at this time.A review of the labeling did not indicate any abnormalities.Residues on the flexible part were evaluated by a medical expert for a similar complaint previously.His comments (excerpts): ¿a surgical instrument with residuals of body fluids or human tissue has no increased risk of infection, if a sufficient sterilization procedure has been made (¿sterile crud¿).¿ only in the (very rare) case of significant contamination with body fluids from a previous patient with massive infection of lps producing germs a small load of endotoxins (lps) may cause a limited local inflammation, which will be hardly registered by the patient.¿ otherwise, no negative side effects for the patient have to be expected, if a surgical instrument is contaminated with (incrusted) residuals of body fluids or human tissue from previous surgeries due to insufficient cleaning and / or the design of the instrument, which would not allow for perfect cleaning.¿ the general cleanability of the screwdriver in the flexible part was proved during design validation.Tests (e.G.Test report 230408cg1) confirmed that germ reduction is being achieved significantly better with automatic [machine cleaning] as well as manual cleaning for the subject product than for comparable other critical instruments [e.G.Endoscopes].¿ furthermore, the requirements for proper reprocessing of medical devices are explicitly described in the brochure ¿instructions for cleaning, sterilization, inspection and maintenance¿ (l24002000).Based on the information given and due to above observations, an exact root cause could not be determined, but the case is rather related to insufficient cleaning by the user.No indications of manufacturing or design related problems were found during the investigation.If the device is returned or if any additional information is provided, the investigation will be reassessed.Device was not received.
