Upon receipt the complaint sample received a visual examination.No markings were found on the device because 89-7202 is not a laser marked product, however, it has been visually confirmed to be 89-7202 per print 36-0011.Upon visual examination, the complaint failure mode was confirmed, the region of the device where the right-angled tip joins the shaft of the device, has exposed insulation in the form of a crack in the insulation around the circumference of the joint.Additionally, some important observations were made during the visual examination.Within the crack in the insulation, a white crystalline substance was observed, this substance may be impurities from the water or latent detergent, either of which most likely deposited itself within the crack as a result of repeated cleaning and sterilization cycles after the crack emerged.Additionally, there is a mild concentration of abrasive marks at the distal end of the insulation suggesting, this device has seen a fair amount of use.If the device were received by the customer in this cracked insulation state, the failure mode would have always been present, and it is unlikely the failure mode would have escaped detection by the customer prior to experiencing the amount of wear necessary to cause the abrasive marks observed, however, it is probable that this failure mode escaped some detection by the customer, enough for the white crystalline substance to have collected in the crack in the insulation.Because a date code was not reported, an age cannot be determined, however, based on sap tahiti transactions with the distributor to this customer, this device was most likely shipped to the customer either 02dec2022 or 25oct2017, indicating this device was either approximately 6 months old or nearly 6 years old.This device is resposable, per instructions for use (ifu) 36-10078, ¿devices labeled as ¿resposable¿ should be discarded after a maximum of 10 uses.Resposable devices with damaged insulation should be discarded immediately.¿ the customer has owned this device for long enough that it is possible those 10 uses were exceeded, and considering a date code was not reported, it is unclear what, if any mechanisms were in place for the customer to track the number of uses this device was subjected to.A complaint history check was performed, no complaints for 89-7202 for cracked or missing insulation were identified over the last 5 years of complaint data.A device history record review could not be performed because the date code of the device is unknown.Based on: 1) the absence of a complaint history for 89-7202 by other customers to indicate either pre-existing cracks or premature wear of the insulation, 2) the absence of a date code under which to perform a device history record review, 3) the presence of abrasive marks and a white crystalline substance within the crack to suggest this device has seen enough repeated cleaning and sterilization for a crack to form, propagate around the circumference of the distal end, and allow the collection of foreign deposits within it and 4) a high likely hood this device is either approximately 6 months old or almost 6 years old, the most probable use of the complaint failure mode is wear, in that this device was most likely used beyond the 10 uses permitted by this device¿s instructions for use.Customer is advised, although no burn marks were observed on the insulation to indicate the device was used with an excessive electrical input or prolonged electrical output, the ifu cautions the following: a) ¿extended energized periods of time without contact to target tissue will increase the opportunity for insulation degradation¿, b) ¿prior to use, all devices should be inspected for cracks, scratches or broken components.Ensure insulation is intact.Any interruptions in the insulation may compromise the safety of the device.¿ and c) ¿start with the lowest possible power setting on the electrosurgical generator.To achieve the desired cutting and coagulation, check the patient circuit and then gradually increase ethe power setting.Note: the output power selected should be as low as possible for the intended purpose.
