Abstract
A surgical access system for use in minimally invasive procedures such as single port or laparoscopic surgery. The system has a sealed base positionable in an incision formed in a body wall and at least two access tubes extending through the base. Each access tube includes a rigid tube having a fixed pre-formed shape including a bend in its distal section. The rigid tubes are restrained against pivotable movement relative to the base, but can be axially rotated and longitudinally repositioned relative to the base. A deflectable tubes extends from the distal end of each rigid tube. Each deflectable tube has a lumen for passage of a medical instrument, as well as a proximal actuator which engages a pullwire to deflect the tube when the user manipulates the instrument's handle.
