Trackwise id (b)(4).Updated sections: b4, g4, g7, h2, h3, h6, h10.The device was returned to the factory for evaluation on 10/04/2023.An investigation was conducted on 10/05/2023.A visual inspection was conducted.Signs of clinical use and no evidence of blood were observed on the device.The c-ring, bisector electrodes, and bisector blade were observed to be intact with no visual defects observed.The pullrod ball from the rocker assembly was returned loose.A mechanical evaluation was conducted.The c-ring was able to be retracted and extended using the c-ring slider with no physical or visual difficulties.The bisector rod was also able to be retracted and extended within the cannula with no physical or visual difficulties; however the bisector blade was unable to be extended and retracted using the toggle.The rocker assembly was unable to be used to extend and retract the blade and did not function properly.The rocker assembly was unscrewed so the individual pieces could be examined.A microscopic investigation was conducted.The pullrod ball was returned separately and therefore out of the socket of the rocker arm, providing no connection between the two components.Due to the lack of connection, the assembly came apart when the screws were removed with no physical force used.As demonstrated in the dhr, the device undergoes the final testing described in (b)(4) part 6 (tool inspection) to ensure that the assembled device functions as expected before release from the factory.Based on the returned condition of the device and the evaluation results, the reported failure "mechanical problem" was confirmed.The lot # 3000323217 history record review was completed.There were no ncmrs, rework, or deviations documented for the reported lot number.Based on the dhr/lhr review results, it was determined that there is no relation between the batch manufacturing process and the reported failure.
