Reported narrative: MEDTRONIC RECEIVED INFORMATION REGARDING A GUIDANCE SYSTEM BEING USED DURING A SPINAL PROCEDURE. IT WAS REPORTED THAT A SINGLE LEVEL MIS TLIF AT L4-L5 PROCEDURE WAS PLANNED. AFTER THE RIGHT L5 GUIDEWIRE WAS INSERTED, THE SURGEON REALIZED THERE WAS SOMETHING WRONG WHEN INSERTING THE RIGHT L4 GUIDEWIRE. IMAGING WAS DONE WITH THE C-ARM AND THE SURGEON FOUND THEY WERE NOT IN THE PLANNED TRAJECTORIES. THE SCREWS INTENDED FOR L5 WERE AT L4 AND THE SURGICAL ARM WAS SENT TO THE WRONG LEVEL. TROUBLESHOOTING INVOLVED CHECKING THE PLAN AND LABELING AND RESENDING THE SURGICAL ARM TO THE TRAJECTORY. THE SURGEON DECIDED TO ABORT THE USE OF THE GUIDANCE SYSTEM AND COMPLETE THE PROCEDURE FREEHAND USING THE C-ARM. THE PATIENT'S L3 EXITING NERVE ROOT WAS DAMAGED, BUT THE PATIENT'S MOTOR FUNCTION WAS NOT IMPACTED. THE PATIENT WAS STILL UNDER OBSERVATION. THE PROCEDURE WAS DELAYED TWO HOURS.

Reported narrative: IT WAS REPORTED THAT DURING A DA VINCI-ASSISTED SURGICAL PROCEDURE THE HARMONIC ACE INSTRUMENT BROKE AND THE INSTRUMENT TIP WAS MISSING. THE SITE WAS CONTINUING THE PROCEDURE AS PLANNED AT THAT TIME. INTUITIVE SURGICAL INC. (ISI) FOLLOWED UP WITH THE DA VINCI COORDINATOR AT THE SITE AND OBTAINED THE FOLLOWING ADDITIONAL INFORMATION ON (B)(6) 2021. THE FRAGMENT FROM THE HARMONIC ACE INSTRUMENT WAS RETRIEVED MANUALLY BY THE SURGEON AFTER THE PROCEDURE WAS COMPLETED. AN X-RAY WAS PERFORMED, BUT THERE WAS NO ADDITIONAL PROCEDURE REQUIRED TO RETRIEVE THE FRAGMENT. THE INSTRUMENT WAS IN USE FOR AN UNKNOWN AMOUNT OF TIME BEFORE THE ISSUE OCCURRED AND IT WAS UNKNOWN IF THE HARMONIC ACE WAS INSPECTED PRIOR TO USE. THERE WAS NO INSTRUMENT COLLISION AND THE INSTRUMENT WAS REMOVED THROUGH THE CANNULA WITH THE WRIST STRAIGHTENED. THE CAUSE OF THE INSTRUMENT BREAKAGE WAS NOT KNOWN. THERE WAS NO REPORT OF PATIENT INJURY AS A RESULT OF THE ISSUE. ALTHOUGH THE INSTRUMENT WAS REQUESTED TO BE RETURNED FOR ANALYSIS, THE CUSTOMER WAS UNSURE IF IT WOULD BE RETURNED. NO IMAGES OR PROCEDURE VIDEOS WERE AVAILABLE FOR REVIEW.

Reported narrative: IT WAS ORIGINALLY REPORTED THAT DURING A DA VINCI-ASSISTED OVARIAN CYSTECTOMY SURGICAL PROCEDURE, A MONOPOLAR CURVED SCISSORS (MCS) INSTRUMENT WAS BENT TO THE LEFT AND COULD NOT BE REMOVED THROUGH THE CANNULA. THE MCS INSTRUMENT AND THE CANULA WERE REMOVED TOGETHER FROM THE PATIENT. UPON REMOVAL, IT WAS NOTED THAT FRAGMENTS FROM THE MCS TIP COVER ACCESSORY WERE MISSING AND HAD FALLEN INSIDE THE PATIENT. THE SURGEON LOCATED AND RETRIEVED TWO FRAGMENTS, BUT THEY DID NOT EQUAL THE SIZE OF THE PIECE THAT WAS MISSING FROM THE MCS TIP COVER ACCESSORY. THE LOCATION OF THE MISSING FRAGMENT(S) WAS UNKNOWN. ON 30-SEPTEMBER-2021, ISI CONTACTED THE ROBOTICS COORDINATOR (THE ORIGINAL REPORTER) AND OBTAINED THE FOLLOWING ADDITIONAL INFORMATION ABOUT THE EVENT. THE MCS INSTRUMENT AND THE MCS TIP COVER ACCESSORY WERE INSPECTED BEFORE THE PROCEDURE AND THERE WAS NOTHING NOTED OUT OF THE ORDINARY. SHE DID NOT KNOW WHAT CAUSED THE MCS TO BE DAMAGED AND DID NOT KNOW IF THERE WAS AN INSTRUMENT COLLISION. A ROBOTIC INSTRUMENT OF AN UNKNOWN TYPE WAS USED TO RETRIEVE THE FRAGMENTS. THEY DID AN X-RAY, BUT NO FRAGMENTS WERE VISIBLE. NO ADDITIONAL PROCEDURES WERE REQUIRED TO REMOVE FRAGMENTS. SHE IS NOT AWAR

Reported narrative: IT WAS REPORTED THAT AFTER COMPLETION OF A DA VINCI-ASSISTED RADICAL PROSTATECTOMY WITH LYMPHADENECTOMY PROCEDURE, A PATIENT HAD REACHED OUT TO THE SURGEON; STATING A POST-OPERATIVE ¿BURN ON HIS UMBILICUS¿ WAS IDENTIFIED. PHOTOGRAPHS OF THE AFFECTED AREA WERE SUPPLIED TO THE SURGEON BY THE PATIENT. THE IMAGES DEPICTED A ¿PRESSURE ULCER,¿ WHICH THE SURGEON INDICATED WERE FROM A 3RD PARTY 12MM DISPOSABLE CANNULA DURING THE COURSE OF THE PROCEDURE, THE CANNULA MAY HAVE BEEN RUBBING UP AGAINST THE PATIENT POSSIBLY CAUSING THE ULCER. THE SURGEON BELIEVES THAT THE PRESSURE OF THE INDIVIDUAL AND THE CANNULA MAY HAVE CAUSED THIS. THE INITIAL DA VINCI PROCEDURE WAS COMPLETED WITH NO KNOWN OR REPORTED INJURY. ON (B)(6) 2021, INTUITIVE SURGICAL, INC. (ISI) OBTAINED THE FOLLOWING ADDITIONAL INFORMATION REGARDING THE REPORTED EVENT FROM THE CONSOLE SURGEON: THE SURGEON STATED THAT, ¿BELOW THE UMBILICUS IS JUST THE CLOSED PORT SITE WITH STERI-STRIPS AND DRIED BLOOD,¿ AND THAT ¿THE CRESCENT SHAPED RED AREAS¿ ABOVE THE UMBILICUS IS WHERE THE ARM PROBABLY PUSHED DOWN AND CAUSED THE PRESSURE ON A ¿DISPOSABLE 10/12 THIRD PARTY TROCAR BY ETHICON.¿ THE SURGEON SAID THAT IT APPEARS TO BE AN ABDOMINAL ¿P
