Abstract
Abstract A specimen retrieval tube for use in minimally invasive diagnostic and/or surgical procedures includes an elongated fluid impervious and, preferably, transparent tube; a first end cap positioned at the proximal end of the tube and having a main body portion with an aperture therethrough, and a capping tab flexibly attached to the main body portion, the capping tab having a plug projecting therefrom for engaging the aperture and forming a fluid tight seal therewith; and a second end cap for engagement with the distal end of said tube. The specimen retrieval container is adapted for use with a trocar cannula. During use, the tube is inserted through the cannula. A grasper may be disposed through the specimen retrieval container and used to grasp the tissue sample and move it into the bore of the tube. The tube is then withdrawn from the cannula and sealed.
