Patent attributes
A depth limiter that is configured to couple with a cannula tube of a trocar having a tube cross dimension. The depth limiter includes an outer frame portion and an inner gripping portion housed within the outer frame portion. The inner gripping portion includes a plurality of lobes flexible relative to each other between a relaxed configuration and at least a first flexed configuration. In the relaxed configuration the plurality of lobes collectively form a first effective cross dimension configured to be less than the tube cross dimension. In the first flexed configuration the plurality of lobes collectively form a second effective cross dimension greater than the first effective cross dimension and configured to be equal to the tube cross dimension such that the second effective cross dimension is sized to restrict axial movement of the depth limiter relative to the cannula tube of the trocar.
