The dissector developed by the authors is a stainless steel instrument, 20 cm in length, 1 cm in diameter, with a cylindrical handle, and an articulated section 3 cm in length and 1cm in diameter at the distal end. When the most proximal end of the handle is rotated, the articulated section provides for angulation or articulation of the distal end portion with respect to the longitudinal axis of the instrument that is similar to the movements of a distal phalanx of a finger.
