Mechanisms for controlling rotation of outer cannula for use in endoscopic tool

A method comprising:

• inserting an endoscope within a subject;
• inserting a cutting assembly within a working channel of the endoscope, the cutting assembly extending from a proximal end to a distal end, the cutting assembly comprising an outer cannula and an inner cannula disposed within the outer cannula;
• positioning the cutting assembly at a site within the subject;
• rotating the outer cannula to position a window of the outer cannula adjacent a region of the site from which to resect material by rotating a proximal tubing end of a flexible outer tubing, the flexible outer tubing extending from the proximal tubing end to a distal tubing end, the distal tubing end coupled to the outer cannula, wherein the flexible outer tubing includes a plurality of first wires and a plurality of second wires oriented at an angle relative to the plurality of first wires, the plurality of first wires and the plurality of second wires each including more than eight wires and less than twenty four wires;
• and
• rotating, by a drive assembly, a flexible torque component coupled to a proximal end of the inner cannula to rotate the inner cannula relative to the outer cannula to resect the material.
