Abstract
Abstract A specimen removal pouch and applicator includes a pouch fabricated from a flexible membrane, a drawstring thread forming a running noose disposed circumferentially round the end of the pouch, an endoscopic tubular portion, and a pusher rod having an aperture for permitting the passage therethrough of a single thread. When the drawstring thread is pulled, the knot is stopped at the aperture and the noose is closed, thereby closing the mouth of the pouch. The pouch is detached from the apparatus.
