19. A depth limiter configured to couple with a cannula of a surgical access device, the depth limiter comprising:
(a) first and second user contact portions configured to be actuated by a user, wherein the first and second user contact portions are positioned on opposing sides of the depth limiter;
(b) a biasing portion at least partially defining an opening, wherein the first and second user contact portions are configured to transition the biasing portion between a fixed configuration and a movable configuration; and
(c) a gripping surface positioned within the opening and aligned with the biasing portion,
wherein the gripping surface is configured to couple with the cannula of the surgical access device when the biasing portion is in the fixed configuration to thereby inhibit longitudinal translation of the depth limiter along the cannula, and to decouple from the cannula when the biasing portion is in the movable configuration to allow longitudinal translation of the depth limiter along the cannula,
wherein the gripping surface includes a plurality of teeth, wherein each tooth of the plurality of teeth is configured to engage a rib of the cannula of the surgical access device to thereby inhibit longitudinal translation of the depth limiter along the cannula when the biasing portion is in the fixed configuration, and
wherein the biasing portion comprises an arm positioned between the first user contact portion and the second user contact portion, wherein the arm is configured to move the gripping surface from the fixed configuration to the movable configuration, and wherein a longitudinal axis through the arm intersects a normal axis extending through the first user contact portion at approximately 90 degrees.
