D11: concomitant medical products and therapy dates.Section h3, h6: the ri robotic drill attachment, part number rob10015, s/n (b)(6), used in treatment was returned for evaluation.A relationship between the reported event and the device was established.The complaint was visually confirmed.The exterior condition shows minor wear with the drill attachment scraper visibly worn.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 concluded this was an isolated event.The most likely cause of this event is user mishandling.Care and caution should be exercised during the cleaning of the drill attachment.Per the user manual, "scrub all surfaces with a plastic bristled brush, paying particular attention to the crevices around the nose of the robotic drill attachment.Note: do not use rigid cleaning instruments near the plastic scraper in the nose." refer to the cori surgical system user's manual for proper handling.A historical escalation event review was completed.A review of prior escalation actions found no actions applicable to the scope of the reported complaint.The failure mode and associated risk have been anticipated within the risk file and the documented risk level is still adequate.Although no further containment or corrective action is recommended or required at this time, all complaints are monitored and trended through post market surveillance activities.
