Manufacturer Narrative
Intuitive surgical, inc. (isi) received the permanent cautery hook involved with this complaint and completed the instrument evaluation. Failure analysis investigations confirmed the customer reported complaint. Failure analysis found the primary failure of dislodged ceramic sleeve. The instrument was found to have a dislodged ceramic sleeve. No missing material was found. The root cause of dislodged instrument ceramic sleeve is attributed to manufacturing. Additional observation related to the customer reported complaint: the instrument was found to exhibit sleeve thermal damage on the monopolar yaw pulley. The thermal damage was located at the top of the yaw pulley as a result of the dislodged ceramic sleeve. Electrical continuity was tested and passed. The root cause is attributed to a device design. A review of the site's complaint does not show any additional complaints related to this product and/or this event. A review of the instrument log for part# 470183-14/lot# n10210222 0023 associated with this event has been performed. Per logs, the permanent cautery hook was last used on (b)(6) 2022 on system sk4404 with 4 lives remaining. The review of provided image confirmed the customer reported complaint of dislodgement of ceramic sleeve. Based on the additional information obtained from failure analysis investigation, this complaint is being reported due to the following conclusion: there was evidence of thermal damage on the monopolar yaw pulley of the ceramic sleeve. Thermal damage on the monopolar yaw pulley of ceramic sleeve is evidence of electrical discharge at a location other than intended. While there was no harm or injury to the patient, the reported failure mode could likely cause or contribute to an adverse event if it were to recur.
