1. A surgical system for performing minimally invasive surgical procedures, said system comprising:
an elongated body having a distal end portion, a proximal end portion, an external body surface, an interior region encompassed by the external body surface, and at least a first lumen and a second lumen extending at least partially through the interior region and generally along a direction of a longitudinal axis of said elongated body, wherein the first lumen is configured for receiving an endoscope therein; and a lens having a bullet shaped configuration forming an elongated distal tip that extends distally with respect to said distal end portion of said elongated body, wherein the elongated distal tip comprises a curved and blunt distal end allowing for blunt dissection of tissue and a sidewall extending from a proximal end of the elongated distal tip to the curved and blunt distal end that allows for viewing of the surgical field therethrough.
