Abstract
A working channel for spinal surgery includes a body having a distal end, a proximal end and an interior lumen traversing through the elongate body. The elongate body generally has a parallelogram-shaped cross-section. Another working channel for spinal surgery includes a flared upper section having a distal end, a proximal end and an interior lumen traversing through the flared upper section. The proximal end of the flared upper section is wider than the distal end of the flared upper section. The working channel also includes a lower section extending from the distal end of the flared upper section. The lower section has a distal end, a proximal end and an interior lumen traversing through the lower section. The lower section generally has a parallelogram-shaped cross-section.
