Articulating surgical access system for laparoscopic surgery
First Claim
1. A surgical system, comprising:
- at least one arm defining a longitudinal passageway extending therethrough configured to receive a surgical instrument therein, the at least one arm including 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 including 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 coupled to the proximal portion of the at least one arm, the first articulation assembly transitionable between a first state and a second state for articulating the first articulatable segment between the substantially straight configuration and the articulated configuration, the first articulation assembly including a lever and a base, the first articulatable segment articulating between the substantially straight configuration and the articulated configuration in response to the lever moving relative to the base between a spaced-apart position and an approximated position; and
a second articulation assembly coupled to the proximal portion of the at least one arm, the second articulation assembly different from the first articulation assembly, the second articulation assembly configured to move between a plurality of positions for articulating the second articulatable segment between the substantially straight configuration and the articulated configuration.

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.
