Abstract

The invention provides a self-locking interbody fusion cage system under spinal endoscopic, which comprises a fusion cage body, a self-locking lag screw, a fusion cage holder and a screw handle, the self-locking lag screw is connected to the fusion cage body, the fusion cage holder is used for connecting and operating and installing the fusion cage body, and the screw handle is connected with theself-locking lag screw and operates and installs the self-locking lag screw. The self-locking interbody fusion cage system is suitable for lumbar spinal fusion under spinal endoscopic. The interbody fusion cage is used for solving the problems that in the endoscope-assisted lumbar fusion process, the fusion rate of the interbody fusion cage is low, and trauma is further reduced, the autogenous bone deficiency in the operation process is avoided, the percutaneous endoscope-assisted under-endoscope fusion efficiency can be effectively improved, and the operation safety is greatly improved.

Description

Technical field [0001] The invention belongs to the field of spine minimally invasive fusion, and relates to percutaneous spinal endoscopic assisted lumbar fusion technology, specifically, it particularly relates to how to insert an intervertebral fusion cage into the intervertebral space during minimally invasive fusion surgery, and the implanted intervertebral fusion How to achieve instant stability with the vertebral body by means of self-locking lag screws, and provide a self-locking interbody fusion cage system under spinal endoscope. Background technique [0002] Endoscopic lumabr interbody fusion (Endo-LIF) is one of the current minimally invasive fusion techniques for the precise treatment of lumbar degenerative diseases. It can achieve the same classic minimally invasive translumbar interbody fusion. Consistent clinical effects of the operation, less incision and tissue destruction, no drainage after surgery, faster recovery, local anesthesia can be completed, and more i...
