1. A surgical extractor comprising:
a first arm and a second arm;
a linkage assembly comprising a plurality of links, wherein the linkage assembly is connected to each of the first and second arms at two locations along a length of each of the first and the second arms via separate unique links of the plurality of links;
a driven shaft operatively engaged with the linkage assembly for moving the linkage assembly between a first position such that the first arm and the second arm are separated by a first distance and a second position such that the first arm and the second arm are separated by a second, smaller distance to provide a clamping force; and
a tensioning shaft engageable with the driven shaft for moving the driven shaft relative to the linkage assembly, wherein the tensioning shaft is movable between (a) a locked position wherein the tensioning shaft is disengaged from the driven shaft and locked against axial movement and (b) a tensioning position wherein the tensioning shaft engages the driven shaft to allow for tension to be applied to the driven shaft.
