Event Description

It was reported that during a da vinci-assisted nephroureterectomy surgical procedure, the fenestrated bipolar forceps (fbf) instrument stopped moving, and instrument jaws failed to open while it was grasping the patient¿s tissue.The customer used the instrument release kit (irk) to open the instrument jaws.Then the customer removed the instrument with the cannula together since the instrument was stuck in the cannula.The customer used plier to shave the instrument shaft, straightened the wrist and pulled out the instrument from the cannula.The tip of the instrument was detached from the shaft.The procedure was completed with no reported injury.Isi followed up with the initial reporter and obtained the following additional information: the instrument and cannula were removed together because the instrument wrist came off from the shaft when the surgeon was using the instrument to pull out the tissue.Port incision was not increased to remove the instrument and cannula together.The instrument jaws were grasping the tissue, but no tissue was stuck on the jaws when the issue occurred since irk was used to open the jaws.The instrument pin was not loose, dislodged or missing.No fragment fell into the patient.The customer used a backup cannula to resolve the issue.The system initially powered on without errors.The surgeon did not disable or discontinue the use of the universal surgical manipulator (usm).The procedure was completed robotically with all four usms.
