1. A surgical access assembly, which comprises:
- an outer frame positionable adjacent a patient and defining an opening therein dimensioned to receive a surgical object, and a longitudinal axis, the outer frame including;
a first frame portion having at least one locking projection;
a second frame portion coupled to the first frame portion, the first and second frame portions adapted for relative longitudinal movement between a plurality of select relative positions, the second frame portion having at least one locking tab; and
a lock mounted to one of the first and second frame portions, the lock longitudinally movable relative to each of the first and second frame portions from a first position permitting relative longitudinal movement of the first and second frame portions to a second position to secure the first and second frame portions at one of the select relative positions, the lock dimensioned to couple the at least one locking projection of the first frame portion with the at least one locking tab of the second frame portion upon movement of the lock to the second position; and
a flexible member having a first end connected to the outer frame and a second end positionable within a patient, the flexible member having a passageway extending therethrough, the flexible member being selectively tensioned to retract tissue adjacent the opening during relative longitudinal movement of the first and second frame portions between the select relative positions.

Abstract
A surgical access assembly for positioning within an opening in tissue including an outer frame positionable outside a patient and defining an opening therein dimensioned to receive a surgical instrument therethrough. The outer frame includes a first portion, a second portion and a locking portion. An inner member is positionable within a patient and a flexible member extends between the inner member and outer frame and is spreadable by actuation of the outer frame.
