An access device for accessing an intervertebral disc having an outer shield comprising an access shield with a larger diameter (&#x2dc;16-30 mm) that reaches from the skin down to the facet line, with an inner shield having a second smaller diameter (&#x2dc;5-12 mm) extending past the access shield and reaches down to the disc level. This combines the benefits of the direct visual microsurgical/mini open approaches and the percutaneous, 'ultra-MIS' techniques.

Multi-shield spinal access system

The present invention is directed at minimally invasive systems in which the proximal end portion of the working channel has either zero or a limited range of movement in the lateral direction. A first embodiment has a slidable collar attached to a pair of flanges, wherein movement of the collar is bounded by an annular frame. A second embodiment has a substantially spherical element attached to the tube. A third embodiment has a plurality of caps. A fourth embodiment is adapted for a larger working channel.
