Manufacturer Narrative
|
Intuitive surgical, inc.(isi) received the maryland bipolar forceps instrument involved with this complaint and completed the device evaluation.Failure analysis investigation revealed that the instrument was found with thermal damage at the yaw pulley.Black char marks were observed.Any material missing is likely to be thermal induced rather than mechanically induced.Root cause is attributed to the user.Failure analysis found the primary failure of thermal damage to the bipolar yaw pulley to be related to the customer reported complaint.The electrical continuity test still passed and there was no insulation damage observed to the conductor wire.Additional testing: bipolar energy cord was successfully connected to generator and instrument.Energy activation test was then conducted on system.Wet sponge was held between grips and began to smoke when energy pedal was pressed.No unintended energy leakage was observed.A review of the instrument log was performed.Per the review, the device was last used on the reported event date of (b)(6) 2022 on system (b)(4).The maryland bipolar forceps had 11 use remaining after the last use.A review of the site's complaint history identified no other complaints related to the instrument and/or this event.No image or procedure video was provided for review.Based on the information available at this time, this complaint is being classified as a reportable event due to the following conclusion: it was alleged that the instrument arced.The allegation could be related to the potential for 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.
