This abstract first appeared for US patent application 18975386 titled 'DISABLING SURGICAL TOOLS DUE TO MANUAL BAILOUT
Original Abstract Submitted
A surgical tool includes a drive housing removably coupled to a tool driver of a robotic surgical system, a shaft extending from the drive housing, an end effector arranged at an end of the shaft, and a computer system. The computer system is programmed to send a command signal to a motor of the tool driver to drive rotation of a drive shaft mounted within the drive housing, monitor torque and rotational motion of the motor with a torque sensor and a rotary encoder, respectively, in communication with the computer system, measure an unexpected change in the torque or the rotational motion of the motor with the torque sensor or the rotary encoder when the surgical tool is manually bailed out by manually rotating the drive shaft and backdriving the motor, report the unexpected change as a bailout signal, and disable the surgical tool once the bailout signal is received.
