Abstract
A trocar fixation device includes a cannula and an elongate tube mounted onto and coupled to the exterior surface of the cannula with the distal end of the cannula extending distally beyond the distal end of the elongate tube. The elongate tube includes a plurality of slits cut at an angle to a longitudinal axis of the elongate tube. The trocar fixation device is activated by rotating the proximal-end region of the elongate tube in a first direction and is deactivated by rotating the proximal-end region of the elongate tube in a second direction, opposite to the first direction. Activation of the trocar fixation device compresses the material positioned between adjacent slits and forces the material radially outwardly, away from the exterior surface of the cannula, thereby forming ridges. Deactivation of the trocar fixation device returns the exterior surface of the elongate tube to a substantially smooth condition.
