Updated fields: d9, g3, g6, h2, h3, h4, h6, h11.The forceps cev420 dia 10mm babcock delaitre (cev420) was returned for evaluation: the device history record (dhr) was reviewed, and no abnormalities related to the reported issue were observed.Failure analysis: the moving jaw of the returned forceps was broken.At the point of rupture, a darker area is observed, corresponding to a pre-fracture.Root cause analysis: this area of the breakage was typical of a pre-existing weakness in the material.This weakness was likely due to the initial presence of an inclusion or internal defect, which acted as a crack initiation point.During successive uses of the instrument (the instrument was 15 years old), this weakness facilitated the initiation and propagation of the crack, leading to the final rupture.
