Abstract
A surgical instrument is used to remove excised tissue from an insufflated anatomic cavity through a body wall overlying an endoscopic workspace. The instrument includes an elongate tubular sleeve defining an interior bore fore removing a tissue. The tubular sleeve also called a snake is elastic in its transverse sectional dimension so that the interior bore can expand to accommodate the excise tissue as it is slidably withdrawn through the bore. The sleeve is not elastic in the longitudinal direction due to flexible but non-elastic longitudinal elements integrated into or on the wall of the sleeve.
