Event Description
|
During the surgery, the robot arm was moved to the trajectory and collided with the rosa cover.The impact occurred at the point where the force sensor cable is plugged into the robot arm.Later during the surgery, the force sensor cable was again partially pulled out of the socket while the robot arm was moved to the trajectory because the sterile drape was tied too tightly around the robot arm.The surgeon then loosened the draping and plugged the cable back into the socket.The robot arm was then able to continue to the trajectory.When the surgery was finished the robot arm was moved back to the home position, a communication failure message appeared and rosa shut down, as the force sensor cable was completely removed from the socket.The robot arm was unable to be moved back into park position because the cable of the force sensor was unplugged.

Investigation indicated that the root cause of the reported event is user error.The ifu contains instructions for the user to remain attentive during robot arm movements and to release the vigilance device to stop the robot arm movement if needed.In this specific case the surgeon did not follow those instructions and failed to release the vigilance device to prevent the collision.The device shutdown that occurred after the collision is a normal device behavior.The connector of the force sensor cable have been damaged in the collision, and the cable was not able to be reinserted.Therefore the interface block was replaced for repair purposes.
