A trocar cannula is disclosed. The trocar cannula comprises a cannula having at least one tab member formed therein. Each tab member is configured to provide a retention force between the cannula and tissue when the tab member is placed in a deformed position. The tab member is selectively moveable between a relaxed position, in which the cannula may be moved with respect to the tissue, and the deformed position, wherein the tab member frictionally engages the tissue. |
