1. A surgical cannula system comprising:
- a cannula having a proximal end, a distal end, and a lumen extending therebetween;
a tissue attachment ring having a lumen extending therethrough, the tissue attachment ring being configured to operably couple to a biological tissue; and
a locking mechanism operably coupled to at least one of the cannula or the tissue attachment ring, the locking mechanism having a first locking state and a second locking state;
wherein the cannula is configured to move with respect to the tissue attachment ring when the locking mechanism is in the first locking state and the locking mechanism in the second locking state resists movement of the cannula with respect to the tissue attachment ring.

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.

13. A surgical cannula system comprising:
-
a cannula having a proximal end, a distal end, and a lumen extending therebetween; a tissue attachment ring having a lumen extending therethrough, the tissue attachment ring configured to operably couple to a biological tissue; and a locking mechanism operably coupled to the tissue attachment ring, wherein the locking mechanism is configured to secure a first position of the cannula extending through and relative to the lumen of the tissue attachment ring; wherein the tissue attachment ring further comprises an inner wall defining the lumen of the tissue attachment ring and the locking mechanism includes a first locking element operably coupled to the inner wall. - View Dependent Claims (14, 15, 17, 18, 19, 20)
