Abstract:
A surgical instrument includes a cutting assembly, an outer tubing, and a flexible torque component. The cutting assembly extends from a first proximal end to a first distal end. The cutting assembly includes an outer cannula defining a cutting window and an inner cannula disposed within the outer cannula. The outer tubing extends from a proximal tubing end to a distal tubing end. The distal tubing end is coupled to the outer cannula. The outer tubing is configured to receive a torque at the proximal tubing end and transmit the torque to the outer cannula to rotate the outer cannula. The outer tubing includes a plurality of first wires and a plurality of second wires each including more than eight wires and less than twenty four wires. The flexible torque component is coupled to a third proximal end of the inner cannula to rotate the inner cannula.
