ABSTRACT:
A surgical device has a first cannula formed to define a first interior channel and a second cannula positioned substantially within the first interior channel of the first cannula. The second cannula is formed to define a second interior cannula. Both the first cannula and the second cannula are attached to a conduit piece that defines a first passageway in fluid communication with the first interior channel of the first cannula and a second passageway in fluid communication with the second interior channel of the second cannula. A third passageway defined by the conduit piece is in fluid communication with the first interior channel of the first cannula. The second passageway is covered by a breachable seal that permits insertion of instruments therethrough while limiting undesired fluid flow. A knife blade can be attached to said first cannula and said second cannula can be positioned around the knife blade to shield the knife blade.
