  • PINCH-TO-RELEASE CANNULA DEPTH LIMITER
    Publication number: 20230225760
    Abstract: A depth limiter that is configured to couple with a cannula of a surgical access device. The depth limiter includes first and second user contact portions and first and second biasing features. The first biasing feature includes a first resilient portion and a first gripping surface. The second biasing feature includes a second resilient portion and a second gripping surface. The first and second resilient portions are configured to move the respective first and second gripping surfaces from a fixed configuration to a movable configuration when the respective first and second user contact portions are actuated. In the fixed configuration, the first and second gripping surfaces collectively restrict axial movement of the depth limiter by directly contacting the cannula. In the movable configuration, the first and second gripping surfaces extend parallel to a longitudinal axis and allow for axial movement of the depth limiter relative to the cannula.
