Patent attributes
A surgical access device including a cannula body and a fixation mechanism is disclosed. 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.
