Additional Manufacturer Narrative
Intuitive surgical, inc.(isi) did receive a da vinci product to perform failure analysis and the complaint was confirmed.The debakey forceps instrument was analyzed and found to have a frayed grip cable at the grip hub and idler pulleys.Some wires were broken, but the cable itself was not fully broken.There was no discoloration, corrosion, or contamination observed on the cable that would occur from improper flushing or rinsing during reprocessing.Further inspection found mechanical indentation to the distal pulley that potentially contributed to the frayed grip cable.Additional observation not reported by site that was related to the primary failure included: the instrument had indentations on the outer face of the distal idler pulleys.There were no pieces missing.Grip cable adjacent to this indented pulley showed damage.
