This invention relates to a novel P-approach endoscopic lumbar fusion surgery method, belonging to the field of lumbar fusion surgery technology. This method addresses the high risk of nerve injury and insufficient operational precision in existing endoscopic fusion techniques by proposing an improved solution. It utilizes Kirschner wires for positioning at the inferior articular process to establish a precise entry point avoiding the nerve root pathway; a visually guided circular saw is used throughout the endoscopic procedure to construct a safe triangular working channel directly reaching the spinal canal; under full endoscopic monitoring, a unilateral approach is used for bilateral spinal canal decompression, thoroughly removing diseased tissue and scraping the endplates until punctate bleeding occurs; a bone graft cannula with a curved tip is used to precisely implant the fusion device into the anterior region of the intervertebral space, restoring intervertebral height through a self-locking structure; finally, a universal pedicle screw is percutaneously implanted for fixation. This method reduces the risk of nerve injury, improves surgical safety and efficiency, and is suitable for patients with lumbar spondylolisthesis complicated by spinal stenosis.
