  • Tube names with associated diameters and lengths that are used as part of the flexible drive axis. The two sets of values in the tube length cells of the body tube and placement tube are the ranges of lengths used when constructing flexible implants for SWRS targets DR, PPT, LDT, and LC (R ∼ 9 mm) and deeper VLPO targets (R ∼ 11 mm).
