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;
a lead screw extending between and rotatably mounted to the first and second ends, the lead screw being rotatably coupled at the drive input;
a carriage nut provided within the carriage and mounted to the lead screw such that rotation of the drive input correspondingly rotates the lead screw and thereby translates the carriage along the lead screw and between the first and second ends;
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; and
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 between the first and second ends to thereby translate the carriage along the lead screw, translate the carriage nut along the lead screw, rotate the lead screw, and advance or retract the elongate shaft.
