1. A surgery system for providing intraperitoneal access via a body recess, comprising:
a. a stepped dilator comprising:
a dilator body having a longitudinal axis in a proximal to distal direction;
a first tapered region of the dilator body tapering narrower toward a distal end of the dilator body, the first tapered region having a blunted distal-most portion having a port;
a second tapered region of the dilator body tapering narrower in a distal direction, located proximally to the first tapered region, and separated from the first tapered region by an isolating intervening region, the isolating region being at least 3 mm long and comprises a tapering constriction; and
b. a trocar needle shaped and sized to be passed through the port of the distal-most portion of the first tapered region of the dilator body of the stepped dilator so that a distal tip of the trocar needle extends from the port; and
c. a cannula shaped and sized to be disposed over the stepped dilator,
the cannula having a distal aperture which is slanted relative to a longitudinal axis of the cannula, an edge of the aperture comprising a first edge portion extending along one side of the aperture, and a second edge portion extending along another side of the aperture, wherein the first edge portion extends along a side more distal along the longitudinal axis of the cannula than the second edge portion.
