Manufacturer Narrative

The cori drill, pn rob10013, sn(b)(6), used in treatment, was returned for evaluation.A relationship between the reported event and the device was established.The reported event was confirmed visually and functionally.When a kpc was try, the bur was able to be inserted, but would not be lock/secure.The device was disassemble to inspect the components, and the drill motor slipshaft was found to be broken.As the exposure mechanism is not tied to the slipshaft directly, when the carriage was commanded to expose for the insert of the bur, it was able to by pulling the fractured slipshaft with it.There was no obstruction in front of the leadscrew that would lead to a jam when exposing forward.This allow the bur to be inserted properly, however, would not allow the lock/secure of it.When the carriage retracts to secure the bur, the broken slipshaft would be in the way.This can cause a binding between the slipshaft and splinshaft/carriage.With the carriage unable to retract due to the obstruction, the bur was unable to be secured.The drill was retest with a good tester drill motor, and it operated as design.The bur was secured and the drill passed all testing.A review of manufacturing and service records indicate the device met all specifications upon release into distribution.A complaint history review for similar reported/confirmed complaints has identified prior events.A historical escalation event review was completed.A review of prior escalation actions found no actions applicable to the scope of this case.The failure mode and associated risk have been anticipated within the risk file and the documented risk level is still adequate.The most likely cause of this event is the broken drill motor slipshaft obstruction caused the bur no to be lock/secure.Although no further containment or corrective action is recommended or required at this time, all complaints are monitored through complaint investigation and post market surveillance activities.
