Abstract
Some implementations of the disclosure are directed to single portal surgical systems. In one implementation, an apparatus includes first, second, and third cannulas. Fluid flows through a proximal opening of the first cannula. The second cannula couples within the first cannula such that an outer wall of the second cannula contacts an inner wall of the first cannula. The second cannula includes a first distal opening and a first slot longitudinally extending along the second cannula. Fluid entering the proximal opening flows through the first slot and exits at a distal end of the. The third cannula couples within the second cannula such that an outer wall of the third cannula is in touching relation with an inner wall of the second cannula. The third cannula includes a second distal opening that rotationally interacts with the first distal opening during tissue debridement.
