Abstract

A surgical cannula system. The surgical cannula system includes a cannula having a proximal end, a distal end, and a lumen extending therebetween. A tissue attachment ring, being configured to be coupled to a biological tissue, includes a lumen extending therethrough. A locking mechanism has a first locking state, in which the cannula is configured to move with respect to the tissue attachment ring, and a second locking state, in which movement of the cannula with respect to the tissue attachment ring is resisted.
