1. A method comprising:
introducing a tubular body of a specimen retrieval device having a proximal portion and a distal portion through a body opening into a body cavity;
introducing an articulation shaft having a proximal portion, a distal portion, and an articulation knob through a longitudinal bore of the tubular body such that the distal portion of the articulation shaft is coupled to a support member that is pivotably supported about a pivot axis on the distal portion of the tubular body;
positioning the distal portion of the tubular body within the body cavity to position a specimen receptacle supported on the support member in the body cavity;
actuating the articulation knob of the articulation shaft to articulate the support member about the pivot axis to reposition a first opening of the specimen receptacle in relation to a tissue specimen from a non-articulated position to an articulated position;
removing a second opening of the specimen receptacle from the body cavity;
passing the tissue specimen through the first opening of the specimen receptacle with the first opening in the articulated position into the specimen receptacle and out the second opening; and
removing the specimen retrieval device from the body cavity.
