Patent ID: 6976957

Claim:
Surgical apparatus comprising: an elongated cannula having an elongated axis between distal and proximal ends, 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 distal and proximal ends of the cannula in substantial diametric orientation therein relative to the endoscope lumen; an auxiliary lumen extending as a hollow bore between distal and proximal ends of the cannula in substantially orthogonal orientation therein relative to the diametric orientation of the endoscope lumen and instrument lumen; and an elongated support slidably disposed within the bore of the auxiliary lumen to selectively extend beyond the distal end of the cannula, and including an end effector mounted distally on the elongated support for movement therewith beyond the distal end of the cannula.
