Wound retractor including rigid ring
First Claim
1. A wound retractor for accessing a body cavity, the wound retractor comprising:
- a proximal ring configured for disposition outside of the body cavity including an inflatable member that is adjustable to a plurality of radial dimensions;
a distal ring configured for disposition inside the body cavity;
a flexible sleeve extending between the proximal and distal rings and defining a passage for reception of an object, the proximal ring configured to adjust a radial dimension of the flexible sleeve to retract tissue;
a rigid ring member that is separately insertable by a user during a surgical procedure into a space directly adjacent to an inner circumferential surface of the proximal ring, the rigid ring member having an outer circumferentially recessed portion configured to receive at least a portion of the proximal ring, the rigid ring member selectively providing rigidity to the proximal ring.

Abstract
A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity adapts to tissue tracts of different widths. The surgical instrument includes a proximal member, a distal member, and a sleeve extending between the proximal member and the distal member and defining a longitudinal passage therein. The proximal member includes an inflatable member that selectively adjusts the radial dimension of the proximal member. A ring member 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, so as to selectively provide rigidity to the proximal member.
