  • Publication number: 20230277214
    Abstract: 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.

  • 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.

  • Publication number: 20210338282
    Abstract: 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.

  • Publication number: 20210338275
    Abstract: A surgical access device includes an obturator head, an elongated shaft extending distally from the obturator head along a longitudinal axis, and an obturator tip. The obturator tip includes a reusable portion and a replaceable tip. The reusable portion is attached to a distal portion of the elongated shaft such that the reusable portion is configured to be sterilized with the elongated shaft. The replaceable tip includes a tapered distal tip and a proximal coupling body. The tapered distal tip is configured to facilitate insertion of the surgical access device through a body wall of the patient. The proximal coupling body is configured to selectively couple with the reusable portion. The replaceable tip, in its entirety, is movable relative to the reusable portion along a mating path in order to couple the proximal coupling body with the reusable portion. The mating path extends laterally relative to the longitudinal axis.

  • Patent number: 9623194
    Abstract: In a first aspect, a safety pen needle assembly is provided herein which includes a hub and a needle fixed to the hub which extends distally from the hub so as to define an injection length. A first shield is slidable relative to the hub from a first state, in which the shield covers at least a substantial portion of the injection length of the needle, to a second state, in which at least a substantial portion of the injection length of the needle is exposed; and, a second shield is slidable from a first position, in which the shield covers the proximal end of the needle, to a second position, in which the proximal end of the needle is exposed. A biasing element is disposed between the first and second shields configured to simultaneously urge the first shield distally and the second shield proximally.
