Event Description
|
It was reported that, during a cori-assisted tka surgery, the swap bur button icon was pressed by accident as it is right next to the planning button.The case was sent back to the bur selection screen and the recalibrate step for the real intelligence robotic drill was necessary, then a calibration error message was displayed and was solved through troubleshooting.The case was exit and re-entered.Upon unlocking the drill a drill disconnect error message was displayed.The drill attachment was checked to see if it was fully looked and the case was exit, the drill was unplugged and plugged back in, the drill attachment was locked and the case was re-entered.A second drill disconnect error message was displayed when unlocking the drill for bur loading.After troubleshooting another drill disconnect error was displayed at the unlock screen (case-(b)(4)).It is unknown if this issue was caused by the real intelligence cori (case-(b)(4)).The drill was swapped, but the long attachment, tracker frame or the exposure guard were not swapped.At this point, the surgeon decided to finish the case with manual instrumentation.No significant delays (fewer than 30 minutes) were reported and the patient was not harmed.Additionally, after the case, the real intelligence robotic drill was assembled and when pressing unlock to load the burr, it was felt that the drill attachment rotated as if the unlocking mechanism of the drill caused the long attachment to rotate (case-(b)(4)).It is unknown if the drill attachment also contributed to this issue (case-(b)(4)).
