Description
Technical Field
The invention relates to the technical field of medical appliances, in particular to a self-locking intervertebral fusion fixing device for a lumbar side front approach.
Background
Currently, posterior approaches such as posterior interbody fusion (PLIF) and foraminal access fusion (TLIF) have been widely used in lumbar surgery. Lumbar fusion requires assistance with internal fixation to achieve its stability, however, these internal fixation methods also damage the posterior group muscles and joints of the spine, thereby increasing surgical trauma, leading to increased degeneration and long-term back pain. In addition, the operation space at the rear is limited, in order to avoid nerve traction injury, the area of the fusion cage is small, so that the intervertebral height is not recovered well, the contact area is small, the intervertebral bodies are not fused easily, and the operation effect is affected.
Anterior Lumbar Interbody Fusion (ALIF) is another method of treating adjacent segment degeneration, recurrent disc herniation, and prosthetic joints, allowing for greater range of decompression and better treatment of the endplates, allowing for convenient placement of large-area fusion cage, and facilitating increased fusion opportunities. In addition, the anterior operation is also beneficial to restoring the height of the intervertebral space. In addition, ALIF avoids post-spinal muscle injury, but because large blood vessels and abdominal organs are often blocked right in front of the surgical space, the surgical site is often required to be operated for a long time, which tends to cause large blood vessel injury, urethral injury, intestinal perforation, incision hernia, intestinal obstruction and retrograde ejaculation, wherein severe large blood vessel injury may lead to death.
For this reason, lateral access to the very lateral interbody fusion (XLIF) has been developed, which greatly reduces the disturbance to the aorta and vena cava, with a lower probability of occurrence of great vessel injury, however, this approach requires to pass through the psoas major, which would damage the lumbar plexus and walk in it, with a higher probability of post-operative leg numbness, pain and weakness. In 1997, mel described for the first time that fusion was performed through the gap between the large blood vessel and the psoas muscle into the disc without passing through the technique of minimally invasive lumbar surgery of the psoas muscle, with less invasion of the psoas muscle and psoas nerve than XLIF. Named oblique approach interbody fusion (OLIF). However, neither XLIF nor OLIF can remove the protruding disc under direct vision, like ALIF, and only indirect decompression can be achieved by distracting the intervertebral space. Therefore, the application range is narrow. And is affected by the ribs and pelvis, often only in the L3/4, L4/5 segments. Because most of the prior XLIF/OLIF lacks a self-locking fusion device, the post-operation needs to be supplemented with the internal fixation of the posterior pedicle screw for sufficient stability, which increases the operation wound and the cost.
For the problems in the related art, no effective solution has been proposed at present.
