Twist-In™ Cannulas

The translucent Twist-In Cannula allows direct visualization of instruments and suture passing. Arthroscopic knot tying is simplified since twisted and tangled sutures can be observed and corrected during arthroscopic knot tying. The threaded design greatly inhibits cannula “fall-out” during instrument removal and allows for capsule retraction for visualization. The side port may be used for irrigation inflow or passive outflow.
