description A surgical cannula includes a seal structure including a one-way check valve and a cannula body. The cannula body includes an insertion portion having a distal opening that is configured to be inserted into tissue, and a receiving portion that includes a proximal opening and is configured to reversibly receive the seal structure. In addition, the seal structure is configured to removably associate with the proximal opening of the cannula body, retain a positive pressure within the cannula body when engaged with the cannula body, and retain a positive pressure within the cannula body when an object is inserted through the cannula and the seal structure. Also, the cannula further includes one or more suture attachment structures extending outward laterally from the cannula body; and one or more internal recesses in an inner wall of the cannula located directly adjacent to the one or more suture attachment structures.
