Abstract
A reducer seal which fits within the cannula handle of the trocar. Contained on the reducer seal there is a seal retainer. Contained on the seal retainer there is a track and movable on the track there is a slide. The reducer track is attached to the trocar housing. The reducer seal retainer is attached to the slide and holds the reducer seal in place. The reducer slide then snaps onto the reducer track. In an 'open' position the reducer slide is held away from an opening in the reducer. Detents on the reducer track hold the reducer in this position. Transverse motion moves the reducer into an active or 'closed' position. The reducer seal slides into frictional engagement on the sealing surface of the reducer track. The reducer has a smaller diameter opening than the trocar cannula.
