Abstract
A depth limiter configured for use with a surgical cannula includes an annular base having a boss that extends about a longitudinal axis and has a boss lumen configured to receive the surgical cannula. A latch arm coupled with the annular base overlies the boss and includes an arm opening configured to align with the boss lumen to receive the surgical cannula. The latch arm is movable relative to the annular base between a release position and a lock position. In the release position the arm opening is positioned coaxially with the boss lumen such that the latch arm is configured to permit longitudinal movement of the depth limiter along the surgical cannula. In the lock position the arm opening is positioned non-coaxially with the boss lumen such that the latch arm is configured to inhibit longitudinal movement of the depth limiter along the surgical cannula.
