Abstract

The invention relates to the technical field of medical treatment equipment, in particular to a lumbar spondylolisthesis intervertebral fusion device under a microscope, which includes a fusion device and a holding device, and the fusion device and the holding device are connected by threads. The invention provides an easy-to-use, small combination height, which is convenient to pass through narrow working channels, and can increase the height of the intervertebral space after combination, so as to achieve the purpose of opening and maintaining the height of the intervertebral space, and at the same time prevent the fusion cage from withdrawing. The installed endoscopic reduction type spondylolisthesis intervertebral fusion device is used to overcome 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...
