Abstract
A robotic surgical tool includes a tool driver including a first inductive coil, a drive housing releasably mounted to the tool driver and including a second inductive coil, a shaft extending from the drive housing and terminating at an end effector operatively coupled to a distal end of the shaft, and a firing rod extending from the drive housing within the shaft and terminating at the end effector, the firing rod including a magnetically responsive material and being movable within the drive housing between a retracted position and an extended position. One of the inductive coils generates a magnetic field, and the other measures an intensity of the magnetic field and a field distortion caused by movement of the firing rod. A change in the field distortion provides an indication of movement of the firing rod between the retracted and extended positions.
