Abstract
A laparoscopy cannula reducer has at its proximal end a resilient end seal carrying a resilient tri-cuspid valve; the valve is passive, yet allows sealing of a body cavity in surgical procedures to prevent fluid flow between the atmosphere and the body cavity, both when an instrument is carried within the cannula and when the cannula is not being used for passage of an instrument to the body and the reducer has handgripping portions for applying and disengaging the reducer over a laparoscopy cannula.
