摘要：
A trocar fixation device includes a cannula and an elongate tube mounted ontoand coupled to the exterior surface of the cannula with the distal end of the cannulaextending distally beyond the distal end of the elongate tube. The elongate tubeincludes a plurality of slits cut at an angle to a longitudinal axis of the elongatetube. The trocar fixation device is activated by rotating the proximal-end regionof the elongate tube in a first direction and is deactivated by rotating the proximal-endregion of the elongate tube in a second direction, opposite to the first direction. Activation of the trocar fixation device compresses the material positionedbetween adjacent slits and forces the material radially outwardly, away fromthe exterior surface of the cannula, thereby forming ridges. Deactivation ofthe trocar fixation device returns the exterior surface of the elongate tubeto a substantially smooth condition.
