THE SURGICAL SYSTEM WAS MOUNTED TO THE PATIENT USING A SCHANZ PIN PLACED IN THE PSIS. ACCURACY WAS NOT CHECKED THROUGHOUT THE PROCEDURE. THE SURGEON DID NOT THINK THE DEVIATION WAS DUE TO THE GUIDANCE SYSTEM AND THEY THOUGHT THE RETRACTOR PUSHED THE CANNULA MEDIALLY. THE AMOUNT OF DEVIATION WAS UNKNOWN. THE USE OF THE GUIDANCE SYSTEM WAS ABORTED AND THE SCREW WAS REPOSITIONED USING NAVIGATION. THE PROCEDURE WAS DELAYED LESS THAN AN HOUR.

ExcelsiusGPS — Injury report filed with FDA (MAUDE). A MAUDE report does not establish that the device caused the outcome. Reported narrative: CASE WAS T10-PELVIS. INTRA-OP WORKFLOW. FIRST TWO REGISTRATIONS (L2-S2 AND S2) WENT VERY SMOOTH WITH NO ISSUES. THIRD SPIN WAS T10-L1. SURGEON PLACED SCREWS T10-T12L. WHEN TRYING TO MOVE THE EE CLOSER TO THE ANATOMY THE ARM WOULD NOT ADVANCE WHEN SURGEON BRACELET WAS ENGAGED. THEN WHEN THE SURGEON TRIED TO RESETTLE THE ARM ONTO TRAJECTORY BY USING THE FOOT PEDAL THE ARM DRIFTED INFERIOR AND DID NOT COME BACK ON TRAJECTORY. I CHECKED THE LOADCELL AND ALL VALUES WERE STEADY AT 0. WE REMOVED THE EE AND ADJUSTED THE DRAPE THEN REPLACED THE EE. TRIED TO NAVIGATE TO A TRAJECTORY AND THE ARM DRIFTED THE SAME WAY. I THEN TRIED A MOTION RESET THAT DID NOT WORK. I THEN TRIED A HARD SHUTDOWN AND THAT DID NOT WORK EITHER. THE SURGEON THEN FREEHANDED THE LAST THREE SCREWS. I REMOVED THE ROBOT FROM THE OR AND REHOMED THE ARM AND THAT SEEMED TO FIX IT BUT COULD NOT CONFIRM DUE TO NOT BEING ABLE TO NAVIGATE TO A TRAJECTORY WITH THE EE. PLEASE SEND AN FSE OUT TO CONFIRM THERE ARE NO HARDWARE ISSUES CAUSING THIS ISSUE.

ROSA Robotic Surgery — Injury report filed with FDA (MAUDE). A MAUDE report does not establish that the device caused the outcome. Reported narrative: DURING THE DBS PROCEDURE MULTIPLE O-ARM SPINS WERE MERGED TO THE FIRST BONE FIDUCIAL O-ARM SPIN. ONLY THE LAST O-ARM SPIN PRESENTED A MERGE ISSUE. THE LATEST CT SCAN WAS ROTATED 90 DEGREES OVERLAYING THE FIDUCIAL O-ARM SPIN. ADJUSTMENTS WERE MADE USING THE ROTATION AND TRANSLATION TOOLS, HOWEVER AFTER RECALCULATING, THE SYSTEM IMMEDIATELY REVERTED TO THE ORIGINAL 90 DEGREE MIS-ORIENTATION. SINCE THE SCANS WERE NOT MERGING CORRECTLY AFTER RECALCULATING, IT WAS ATTEMPTED MERGING THE LAST O-ARM CST TO THE ORIGINAL PLANNING MRI. THIS MERGE PRESENTED NO ISSUES AND AFTER CAREFUL OBSERVATION THE SURGEON ACCEPTED THE MERGE ON THE SOFTWARE. THESE LAST O-ARM SPINS DURING THE OPERATION CONFIRMED ACCURATE ELECTRODE PLACEMENT. HOWEVER, 2 WEEKS POST-OPERATION SURGEON CONTACTED ZIMMER BIOMET CLAIMING THE CT SCANS OBTAINED AFTER PROCEDURE AND O-ARMS DURING PROCEDURES DO NOT MATCH RESULTING IN INACCURATE ELECTRODE PLACEMENT. CUSTOMER IS REQUESTING AN INVESTIGATION TO DETERMINE IF THE MERGING SOFTWARE CONTRIBUTED TO INACCURATE ELECTRODE PLACEMENT.
