Abstract

The invention provides a fully transparent expandable channel system for spinal endoscope-assisted lumbar fusion. The expandable channel system comprises an outer sleeve, an inner sleeve and a step-by-step guide rod, wherein main bodies of the outer sleeve and the inner sleeve are both of semicircular structures; the inner sleeve is sleeved in the outer sleeve and can freely rotate in the outer sleeve along the radial direction; and the step-by-step guide rod penetrates into the inner sleeve. The expandable channel system is used for solving the problem of interbody fusion cage insertion in anendoscope-assisted lumbar fusion process, and damage to walking nerve roots and outlet nerve roots are avoided, so that operation efficiency is greatly improved, fusion efficiency of percutaneous endoscope-assisted endoscope fusion can be effectively improved, and operation safety is greatly improved.

Description

technical field [0001] The invention belongs to the field of spinal minimally invasive technology, and relates to percutaneous spinal endoscope-assisted lumbar fusion technology, specifically, how to insert an intervertebral fusion device into the intervertebral space during the minimally invasive fusion operation, and at the same time, the nerve structure can be seen throughout the process, thereby To reduce the damage to the nerves, it involves an expandable channel system for fully transparent spinal endoscopic assisted lumbar fusion. Background technique [0002] Spinal endoscope-assisted lumbar fusion is one of the mainstream minimally invasive fusion procedures, which has the advantages of small incision, small injury, and fast recovery. The surgical approach is the standard MIS-TLIF, the difference is that with the help of the spinal endoscope system, the upper and lower facet joints are removed endoscopically through the lateral approach, the intervertebral foramen o...
