Manufacturer Narrative

The product was returned for investigation at manufacture and investigation completed on 31 octorber 2023.Upon thorough analysis of the returned endoscope, it was discovered that the angled cover had been improperly handled during its use.The cover had been lifted before insertion into the patient, facilitating the shaft's placement.However, upon removal, the angled cover became dislodged and was unable to be extracted.Additionally, the angled cover lost its original consistency during the operation, obstructing the removal of the sheath from the patient.Due to the prolonged duration of the endoscope within the patient's body (exceeding 3 days), both the sheath and the angled cover sustained further damage.A spot check conducted on october 11, 2023, in the second warehouse focused on evaluating the consistency and fit of the angled cover for various endoscopes.The results indicated that the fit and strength of the angled cover met the required standards for all tested endoscopes.The root cause of observed issues are highly likely attributed to user error.The instruction for use ifu 96136028d_v2.1-09/2022, version bd already contains a caution to check the device for proper functioning before use.Since the second intervention was required to remove the scope, this case is reportable.The event is filed under internal karl storz complaint id: (b)(4).
