The present invention provides an articulating retractor including: a plurality of distal segments, a distal segment of the plurality of distal segments being movable relative to others of the plurality of distal segments; a plurality of proximal segments, a proximal segment of the plurality of proximal segments being movable relative to others of the plurality of proximal segments, the proximal segment corresponding to the distal segment; and multiple sets of cables, the proximal segment connected to its corresponding unit of the distal segment, by a set of cables, such that movement of the proximal segment causes corresponding reciprocal movement of the distal segment. The mechanisms of the articulating retractor may also be combined in such a way to remotely mimic finger movements for manipulation of an object or body tissue.
