  • Publication number: 20210259731
    Abstract: A surgical access assembly includes a cannula including an elongated shaft and a retention anchor movable position along the elongated shaft. The retention anchor includes an annular body and a wiper disposed at a distal end of the annular body. The annular body includes a proximally-facing surface, a distally-facing surface, an outer side surface, and an inner side surface. The inner side surface defines a channel for reception and passage of the elongated shaft therethrough and the proximally-facing surface defines a proximal opening into the channel. The wiper extends radially inwardly of the inner side surface and defines a distal opening into the channel for establishing a sealed relation about the elongated shaft. The distal opening has a smaller diameter than the proximal opening.

  • Publication number: 20210244437
    Abstract: A surgical access device includes a cannula body and a fixation mechanism. The cannula body includes a housing, and an elongated portion extending distally from the housing and defining a longitudinal axis. The fixation mechanism includes a flange, a fixation sleeve, and a proximal sleeve. The flange is rotatable about the longitudinal axis. The fixation sleeve extends distally from the flange and radially surrounds a portion of the elongated portion of the cannula body. The proximal sleeve extends distally from the flange and radially surrounds a proximal portion of the fixation sleeve. Rotation of the flange causes a radially-expandable portion of the fixation sleeve to move between a first position defining a first gap between the radially-expandable portion and the elongated portion, and a second position defining a second, greater, gap between the radially-expandable portion and the elongated portion.

  • Publication number: 20210220010
    Abstract: A surgical access device includes a cannula body and a fixation mechanism. The cannula body includes a housing, and an elongated portion extending distally from the housing and defining a longitudinal axis. The fixation mechanism includes a sleeve and a spring. The sleeve radially surrounds a portion of the elongated portion of the cannula body. The sleeve is rotatable about the longitudinal axis relative to the elongated portion of the cannula body, and the sleeve is longitudinally translatable relative to the elongated portion of the cannula body. A first portion of the spring is engaged with the sleeve, and a second portion of the spring engaged with a distal portion of the elongated portion of the cannula body. Rotation of the sleeve about the longitudinal axis relative to the elongated portion of the cannula body causes a portion of the spring to move away from the longitudinal axis.
