CURVILINEAR SPINAL ACCESS METHOD AND DEVICE

摘要

A curvilinear spinal access device having an expandable working portal. The device includes a slide having a channel with an open top and a movable top sized to cover the open top of the channel forming an expandable working portal with a proximal end and a distal end. The movable top can be moved between a closed position and an open position, wherein in the closed position the movable top blocks direct visualization between the proximal end and the distal end of the expandable working portal and in the open position movement of the movable top results in direct visualization from the proximal end to the distal end of the expandable working portal.
