Abstract
A surgical access port and method for achieving triangulation is disclosed, the surgical access port comprising a housing and an articulation structure. The housing is comprised of a cylindrical member having proximal and distal ends, and defining a longitudinal axis. The articulation structure is comprised of at least two lumens, each of the at least two tubular members disposed in a respective lumen, at least two rotating members disposed along each of the at least two tubular members, an actuating member, and a rigid member connecting each rotating member to each tubular member. The tubular members are configured to receive instruments for use in minimally invasive procedures.
