Abstract:
1. A surgical apparatus comprising: an elongated cannula having an elongated axis between distal and proximal ends of the cannula, and including an endoscope lumen extending as a hollow bore between the distal and proximal ends for slidably receiving an endoscope therein; an instrument lumen extending as a hollow bore between the distal and proximal ends of the cannula in substantial diametric orientation therein relative to the endoscope lumen; a pair of auxiliary lumens disposed in substantially diametric orientation on opposite sides of, and in skewed relation to, the diametric orientation of the endoscope lumen and instrument lumen, at least one of the pair of auxiliary lumens extending between the distal and proximal ends of the cannula; elongated supports slidably disposed within each of the pair of auxiliary lumens to selectively extend beyond the distal end of the cannula; and an end effector transversely mounted between distal ends of the respective elongated supports.
