Abstract
A method of operating a surgical tool includes sending a command signal from a computer system to a motor to drive rotation of a drive shaft mounted within a drive housing of the surgical tool, monitoring one or more operational parameters of the motor with one or more monitoring devices in communication with the computer system, and measuring an unexpected change in the operational parameters of the motor with the monitoring devices. The unexpected change includes a measured operational parameter that is inconsistent with the command signal. The unexpected change is reported to the computer system as a bailout signal, and the surgical tool is disabled once the bailout signal is received at the computer system.
