Abstract
Embodiments of the present disclosure includes method and devices for minimally invasive spinal fusion surgery. A method for minimally invasive spinal fusion surgery can include accessing a spinal column through a working channel device, wherein the working channel has a proximal end and a distal end, advancing the working channel so that the distal end pierces an outer layer of a vertebral disc, inserting a disc extractor through the working channel device and into the vertebral disc to cut the vertebral disc into pieces, inserting a disc blade through the working channel device and into the vertebral disc to cut the vertebral disc into pieces, using a disc rake to remove the pieces of the vertebral disc, inserting a disc shaver to clean a number of surfaces of vertebra adjacent to the vertebral disc, and inserting and implanting a disc implant in a space from where the vertebral disc was removed.
