H10: the navio handpiece (part number 110137 / serial number(b)(6), used in treatment, was return for evaluation.The navio handpiece had an issue where the drill kept popping out of the back of the handpiece during to a procedure on (b)(6) 2018.The initial visual/functional investigation confirmed the reported event.The distance above the wave spring and down to the plunger holder was measured around the circumference of the snap lock.The maximum expected distance was not within specification for this dimension and therefore, the part does not conform to its design specifications.A device history record review found no conditions which could contribute to the reported event and the device met all specifications during release for distribution.A complaint history review found similar reports and this issue will continue to be monitored.The navio surgical system for unicondylar knee replacement and patellofemoral arthroplasty user's manual released at the time of the complaint provides no information regarding the dimensional discrepancies for the distance above the wave spring and down to the plunger holder.This failure is captured in the navio risk profile.The root cause of this issue was found to be due to supplier / raw material fault.The per complaint details, the device malfunctioned during use.Based on the information provided, as the user aborted the procedure and changed to manual instrumentation; there was no surgical delay or patient injury/impact reported.Therefore, no further medical assessment is warranted at this time.
