1. An access device for accessing an intervertebral disc, comprising:
a) an outer shield having a length adapted to extend from an incision to an articular process, a proximal end portion, a distal end portion, an outer surface, and a longitudinal throughbore defining an inner surface,
b) an inner shield having a proximal end portion and a distal end portion; and
c) a video chip disposed in the distal end portion of the outer shield;
wherein the inner shield is configured to be disposed within longitudinal throughbore of the outer shield such that the distal end portion of the inner shield extends distally past the distal end portion of the outer shield; and
wherein the video chip is disposed in a channel of the outer shield and the channel opens into the inner surface of the outer shield at least at the distal end portion of the outer shield.
