Endoscopic reset type lumbar spondylolisthesis interbody fusion cage

Abstract

The invention relates to the technical field of medical treatment equipment, and in particular to an endoscopic reset type lumbar spondylolisthesis interbody fusion cage which comprises a fusion device and a holding device. The fusion device is in threaded connection with the holding device. The invention provides the endoscopic reset type lumbar spondylolisthesis interbody fusion cage which is convenient to use, small in combination height, convenient to pass through a narrow working channel, capable of increasing the height after intervertebral space combination, capable of achieving the purposes of expanding and maintaining the intervertebral space height, capable of preventing the fusion cage from retreating, reliable in fixation and convenient to disassemble and assemble, and is usedfor overcoming the defects in the prior art.

Description

technical field [0001] The invention relates to the technical field of medical treatment equipment, in particular to a mirror-reduced lumbar spondylolisthesis intervertebral fusion device. Background technique [0002] With the development of society, as people work for a long time, people's spine will have scoliosis, degenerative disc disease, disc herniation, osteoporosis, spondylolisthesis and other lesions, resulting in spinal deformation, pain, nerve damage and Partial or complete loss of mobility. [0003] In recent years, with the rapid development of clinical medicine, biomechanics and materials science, in order to treat people's diseases, therapists use posterior lumbar intervertebral fusion to treat patients, and the fusion device is a necessary equipment for treatment. However, new types of fusion devices continue to emerge. Taking materials as examples, carbon fiber polyetheretherketone and absorbable material intervertebral fusion devices have appeared; taking...

Problems solved by technology

[0003] In recent years, with the rapid development of clinical medicine, biomechanics and material science, in order to treat people's diseases, therapists use posterior lumbar intervertebral fusion to treat patients, and the fusion device is a necessary equipment for treatment. However, new types of fusion devices continue to emerge. Taking materials as examples, carbon fiber polyetheretherketone and absorbable material intervertebral fusion devices have appeared; taking shapes as examples, there have been rectangular, bullet-shaped, anatomical intervertebral fusion devices, etc. However, many lumbar intervertebral fusion devices are designed based on open surgery and are not suitable for minimally invasive surgery.
