Articulating surgical access system for laparoscopic surgery
First Claim
1. A method of providing access to an internal surgical site, comprising:
- positioning an access port within an opening in tissue, the access port including at least one lumen extending therethrough;
inserting a first arm through one of the lumens of the access port such that a proximal portion of the first arm is positioned externally of the internal surgical site and such that a distal portion of the first arm is positioned within the internal surgical site, the first arm including a passageway extending therethrough, first and second articulation assemblies coupled to the proximal portion thereof, and first and second articulatable segments positioned along the distal portion thereof;
inserting a first surgical instrument through the passageway of the first arm such that an end effector assembly thereof extends distally from the first arm and such that a handle of the first surgical instrument extends proximally from the first arm; and
manipulating a lever of the first articulation assembly of the first arm to articulate the first articulatable segment of the first arm independent of the second articulation assembly of the first arm to position the end effector assembly of the first surgical instrument for performing a surgical task within the internal surgical site.

Abstract
A surgical system includes one or more arms defining a passageway therethrough. The arm includes a proximal portion configured for positioning externally of a patient'"'"'s body and a distal portion configured for positioning within an internal body cavity. The distal portion includes first and second articulatable segments spaced apart from one another and capable of independent articulation between a substantially straight configuration and an articulated configuration. A first articulation assembly is coupled to the proximal portion of the one arm and is transitionable between a first state and a second state for articulating the first articulatable segment between the substantially straight configuration and the articulated configuration. A second articulation assembly is coupled to the proximal portion of the arm and is configured to move between a plurality of positions for articulating the second articulatable segment between the substantially straight configuration and the articulated configuration.
