Product Overview
The Twist-In, Partially Threaded Cannulas are manufactured from a clear polycarbonate material that allows uninhibited visualization of instruments and sutures through the cannula walls which helps the surgeon prevent suture entanglement and will allow visualization of arthroscopic knots as they are delivered down the cannula. The cannula has threads only on the distal section of the cannula, allowing the surgeon to quickly adjust the working length of the cannula without having to screw or unscrew the entire length of the cannula.
