1. A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity, which comprises:
- a proximal portion defining a continuous tubular wall bendable by a user between an initial position and a bent position;
a compressible distal portion disposed distally with respect to the proximal portion and defining a plurality of longitudinal passages through the compressible distal portion, wherein the compressible distal portion includes a distal annular flange; and
a plurality of bendable structures attached to the proximal portion extending between a first end and a second end of the proximal portion, the plurality of bendable structures configured to maintain the proximal portion in the bent position until the user selectively returns the proximal portion towards its initial position.

Abstract
A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity adapts to tissues having different thickness. The surgical instrument includes a proximal portion with at least one bendable structure attached thereto. The at least one bendable structure is configured to fold anywhere along its length. Folding the at least one bendable structure causes the proximal end of the proximal portion to propagate in a distal direction.
