A system for accessing an intervertebral disc, comprising: an access device, comprising: a) an outer shield having a substantially tubular portion, 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 configured to shield or retract a nerve of the patient, the inner shield having a proximal end portion , a distal end portion , an inner surface , and an outer surface , wherein the outer surface of the inner shield substantially nests within the inner surface of the outer shield so that the inner shield extends distally past the distal end portion of the outer shield , wherein the outer shield comprises a camera in a housing , characterised in that the camera is connected to a single cable extending from the outer shield that includes two tubes for irrigation and suction to clean a lens of the camera and a connector plug that provides power, data and light to the camera, and in that the system further comprises a connector including ball and socket segments , first and second interface clamps , and an inner wire that is put into tension by an adjustable single point fixation handle to block the interface clamps and segments by increasing their absolute friction, wherein the access device is connected to a first interface clamp of the connector and the second interface clamp of the connector is connected to a pedicle anchor such that the access device and camera are stabilized by the pedicle anchor. an access device, comprising: a) an outer shield having a substantially tubular portion, 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 configured to shield or retract a nerve of the patient, the inner shield having a proximal end portion , a distal end portion , an inner surface , and an outer surface , a) an outer shield having a substantially tubular portion, 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 configured to shield or retract a nerve of the patient, the inner shield having a proximal end portion , a distal end portion , an inner surface , and an outer surface , wherein the outer surface of the inner shield substantially nests within the inner surface of the outer shield so that the inner shield extends distally past the distal end portion of the outer shield , wherein the outer shield comprises a camera in a housing , characterised in that the camera is connected to a single cable extending from the outer shield that includes two tubes for irrigation and suction to clean a lens of the camera and a connector plug that provides power, data and light to the camera, and in that the system further comprises a connector including ball and socket segments , first and second interface clamps , and an inner wire that is put into tension by an adjustable single point fixation handle to block the interface clamps and segments by increasing their absolute friction, wherein the access device is connected to a first interface clamp of the connector and the second interface clamp of the connector is connected to a pedicle anchor such that the access device and camera are stabilized by the pedicle anchor. <EOS>
