Abstract
A specimen removal apparatus includes a pouch assembly fabricated from a flexible membrane, a pouch support, a drawstring having a knot and forming a noose disposed circumferentially around a mouth of the pouch assembly, an endoscopic tubular portion, and a drive rod. The pouch support includes a rocker arm assembly attached to a distal end of the drive rod. Proximal pulling of the drawstring closes the noose, thereby closing the mouth of the pouch assembly. The pouch assembly is detachable from the apparatus.
