1. A system comprising:
an endoscope comprising:
a lens disposed at a distal end of the endoscope and configured to gather and focus light toward an image sensor;
wherein the lens is angled at a viewing angle relative to a plane extending transversely to a longitudinal axis of the endoscope such that the viewing angle is not perpendicular to the longitudinal axis of the endoscope;
an obturator comprising an obturator lumen, wherein the obturator lumen is configured to receive the endoscope, and wherein the obturator further comprises:
a tip located at a distal end of the obturator lumen, wherein the tip is configured to puncture a patient's tissue, and wherein at least a portion of the tip is transparent; and
a prism configured to bend the light toward the lens along a plane that is substantially perpendicular to the lens.
