Integrated intervertebral treatment cage

Abstract

The invention discloses an integrated intervertebral treatment cage. The integrated intervertebral treatment cage comprises a body and a connecting driving device connected with the body, wherein thebody comprises a retractor and a supporting scraping device, wherein the supporting scraping device is arranged inside the retractor and is connected through bolts. A threaded connecting part is further arranged at one end of the body, a plurality of first socket joint grooves are formed inside one end, far away from the body, of the threaded connecting part, and flanges are further arranged on internal walls below the first socket joint grooves. The connecting driving device comprises a driving connecting link I, a driving connecting link II and a driving connecting link III, a friction partand a connecting part are separately arranged at the two ends of each driving connecting link, and each driving connecting link is in driving connection with the body through a driving part. An intervertebral disc and a cartilage end plate are scraped off and taken out through the body implanted into a human body, the bulgy body plays a role in supporting adjacent vertebral bodies, finally, a filler is implanted into the body to complete filling, and intervertebral disc excision and cage implanting are completed in one time so as to achieve supporting on the vertebral bodies.

Description

technical field [0001] The invention relates to a fusion device, in particular to an integrated intervertebral treatment fusion device, which belongs to the technical field of medical instruments. Background technique [0002] Cervical and lumbar degenerative diseases are the most common spinal surgery diseases in recent years, which seriously affect the work and life of patients. Once non-surgical treatments such as medicine and physical therapy fail, surgical treatment is often the only effective method. In particular, degenerative spondylolisthesis, segmental instability, intervertebral disc-derived disease, low back pain caused by lumbar instability caused by traumatic spondylolisthesis, and limb motor sensory impairment generally require lumbar fixation and fusion. In the 1950s, Cloward first proposed posterior lumbar fusion (PLIF), which has developed into one of the basic procedures of spinal surgery today. In 1986, Badgy and Kuslch designed an intervertebral fusion ...

Problems solved by technology

However, this utility model can only play the role of supporting and implanting fillers, and cannot be scraped, so further improvement is needed

[0005] In the prior art, the commonly used treatment method is to scrape off and take out the intervertebral disc and cartilage endplate of the spine, and then implant the intervertebral fusion device into the spine to support and restore the height of the intervertebral space of the spine. There is often a bone graft compartment in the middle of the fusion cage, which is used to put in autologous bone, human bone or allogeneic bone that can form bone fusion with the vertebral plate. According to different parts, the fusion cage can be designed into different shapes. However, in the existing technology, multiple operations are often required to complete the work of scraping, supporting and implanting, and more tools are used, and the steps are more cumbersome, which increases the difficulty of the operation
