ADAPTER SEAL FOR LAPAROSCOPIC CANNULA

摘要

An adapter seal adapted to facilitate the use of a small instrument within a laparoscopic cannula. The adapter seal comprises a body portion formed of elastomeric material, and a relatively rigid insertion guide mounted on the body portion. The body portion has an aperture therein adapted to sealingly engage and support the small instrument while permitting movement of the instrument through the aperture. The insertion guide has a wall forming a generally conical passageway for guiding small instruments toward the aperture of the body portion. A tether may be provided for holding the adapter seal adjacent the cannula when the body portion is disconnected from the cannula, and the insertion guide may be color-coded to indicate the size aperture through the body portion of the adapter seal.
