The surgical instrument (10) includes a proximal member (110), a distal member (120), and a sleeve (130) extending between the proximal member (110) and the distal member (120) and defining a longitudinal passage therein. The proximal member (110) includes an inflatable member (140) that selectively adjusts the radial dimension of the proximal member (110). A ring member (150) may be separately insertable by a user during a surgical procedure into the space directly adjacent to the radially-inner surface of the inflatable member (140), so as to selectively provide rigidity to the proximal member (110).1/3 2 10160 114 110 112 130 120 G106 105 FIG. 1
