摘要： A depth limiter that is configured to couple with a cannula tube of a trocar. The depth limiter includes a body having first and second body portions coupled together and pivotable between open and clamped configurations. The body includes first and second inner surfaces presented by the first and second body portions. In the clamped configuration the first and second inner surfaces form a first cross dimension sized to restrict axial movement of the depth limiter relative to the cannula tube. In the open configuration the first and second inner surfaces form a second cross dimension sized to permit axial movement of the depth limiter relative to the cannula tube. The depth limiter includes first and second locking members, one of which is resiliently biased to engage the other. The locking members are configured to engage each other to lock the body portions in the clamped configuration.

摘要： 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.
