1. A surgical tool, comprising:
a drive housing having opposing first and second ends and a drive input rotatably mounted to the drive housing at the first end;
a carriage mounted entirely within the drive housing and movable between the first and second ends via actuation of the drive input, the carriage including one or more distal layers and one or more proximal layers attachable to the one or more distal layers;
an instrument driver matable with the drive housing at the first end and including a drive output matable with the drive input such that rotation of the drive output correspondingly rotates the drive input to thereby translate the carriage within the drive housing;
an elongate shaft coupled to and extending distally from the carriage and penetrating the first end and the instrument driver;
a fin connected to the carriage and accessible by a user at an exterior of the drive housing, the fin being manually translatable along the exterior of the drive housing to thereby translate the carriage and simultaneously advance or retract the elongate shaft; and
a bailout mechanism operable to unlock the one or more proximal layers from the one or more distal layers such that the one or more proximal layers are removable from the drive housing,
wherein the bailout mechanism includes a releasable pin movable between a locked position, where the one or more proximal layers are secured to the one or more distal layers, and an unlocked position, where the one or more proximal layers are unsecured from and movable relative to the one or more distal layers.
