Manufacturer Narrative
|
Intuitive surgical, inc.(isi) received the monopolar curved scissors (mcs) tip cover accessory involved with this complaint and completed the device evaluation.Failure analysis investigations confirmed the reported complaint.The mcs tip cover accessory was found to have tearing at the mouth.The tears were axially aligned with the mcs tip cover accessory and measured from 0.076¿ in length.There were no signs of thermal damage present at the end of any tears.Tears at the mouth are most commonly caused by repeated thermal and mechanical stresses.The root cause is attributed to a component failure.An additional observation was also identified.Visual inspection observed a burn hole at the center of the mcs tip cover accessory.The burn measured 0.044" x 0.052" in length.There was no mcs instrument that was returned with the reported accessory.There was no thermal damage exhibited at either end of the mcs tip cover accessory.It is likely that the burn was caused by another energized instrument due to no thermal damage found at the ends of the accessory.The root cause is typically attributed to mishandling/misuse.Verification of the accessory product via system logs cannot be performed because accessory device product details are not captured in the system log.A review of the site's complaint history does not reveal any related complaints involving this product or this event.No image or video of the procedure was provided for review.This complaint is being reported due to the following conclusion: failure analysis observed a burn hole at the center of the mcs tip cover accessory.In the event the tip cover is compromised, it is possible for energy to discharge in an area other than the instrument tip.While there was no report of harm or injury to the patient, the reported failure mode could likely cause or contribute to an adverse event if it were to recur.
