TROCAR SYSTEM HAVING SHIELDED TROCAR, CANNULA WITH FINGER GRIPS, REMOVABLE END HOUSING AND FLEXIBLE VALVE SYSTEM, AND ASSOCIATED METHODS.

摘要

A trocar system and associated methods are provided. The trocar system preferably has a cannula having an elongate cannula body. The cannula body includes medial and distal portions thereof having a first diameter and a proximal portion thereof connected to the medial portion and having a second diameter. The second diameter is preferably larger or greater than the first diameter. A cannula body end housing is readily detachably connected to the proximal portion of the cannula body for housing at least one valve therein. First and second trocar valves are positioned within the cannula body end housing and each having an opening in a medial portion thereof. The first valve is preferably positioned proximal of the second valve. A pair of finger grips are each connected to and extending outwardly from the proximal portion of the cannula body for gripping the cannula with the fingers of a hand of a user. A trocar or other instrument is positioned within the cannula body.
