摘要:
A surgical access device is provided having a cannula and obturator. The cannula has a housing and tube section with an anchor located about the tube section. The obturator has a mechanism to deploy the anchor and adjust the cannula length. The anchor is moveable between a deployed and undeployed state where the undeployed state facilitates insertion and removal of the access device and the deployed state assists in fixation of the cannula in an anatomic structure. Anchor deployment is independent of cannula length adjustment.
