Abstract
An arthroscope cannula including inner and outer intimately engaged concentric tubes with the inner tube having a longitudinally extending wall depression defining, in conjunction with the outer tube, a pressure passage. The inner tube receives the scope which is restrained therein by the wall depression to define an inflow fluid passage. The outer tube is selectively removable from about the inner tube with both tubes mounting on and projecting from a flow controlling and directing bridge assembly.
