Abstract
A novel reducer system is provided for a trocar cannula. The reducer system fastens to the cannula end and a living hinge allows a reducer cap to be closed over the cannula lumen to allow the cannula to be used with smaller diameter surgical instruments. By fastening the reducer system to the exterior of the cannula end, the system can be placed in position on the cannula prior to surgery, even while a large diameter obturator is used with the cannula.
