Event Description

During a procedure to place 13 electrodes for a seeg, the following events occurred: upon turning on the rosa robot, the emergency stop button was on when not pressed. The robot had to be turned off, unplugged and plugged back in. When the initial reference points were registered, it was not possible to correct them according to the usual procedure. The recalibration had to be redone and then, during the second attempt, a manual correction of the "blue points" by superimposing them on the "red ones" was performed. The robot then asked to revalidate all the points. During the laser scanning (wings of the nose and temples of the patient), the scanning of the left temple never ended, it was necessary to cancel the scanning of this zone, no cause was found. The other areas could be scanned normally. During the accuracy check, the mandatory points of the check procedure could be validated but only one additional check point could be validated. An error message was displayed after checking this point "the robot is in a singular position. The cooperative mode will be restarted in slow speed". The accuracy of the recalibration was correct. It was therefore decided to continue the procedure. The first 9 electrodes were positioned according to the procedure. During the implantation of the tenth electrode, no one was pressing the pedal and the mobility was set to "axial". The arm made a movement that was not at all in line with the trajectory. A piece of the coagulation electrode broke off in the patient's skull. According to our information, there were no clinical consequences for the patient after the seeg electrode placement surgery. This electrode #10 was therefore not implanted. Then, the 3 last electrodes implanted were reportedly off by ~5mm. During the regularly planned seeg electrode removal surgery, the surgeon successfully removed the part of the coagulation electrode sheath that fractured and remained implanted, as reported by the clinical services team after an additional follow-up discussion with the surgeon. No adverse consequence for the patient was reported other than the additional scar resulting from the trepanation of the skull that was needed to proceed.
