Description
Technical Field
The invention belongs to the technical field of interbody fusion devices, and particularly relates to a lumbar interbody fusion device.
Background
Lumbar interbody fusion procedures are commonly used to treat lumbar degeneration and instability, to restore interbody height with the aid of an interbody fusion cage, to enlarge the foramen, to support the anterior column, and to increase fusion segment stability.
Existing lumbar interbody fusion devices mainly include non-expansion interbody fusion devices (e.g., lumbar interbody fusion devices as disclosed in document CN 209611432U) and expansion interbody fusion devices (e.g., expandable interbody fusion devices of document CN 203749649U). The inflatable interbody cage has the main advantage of achieving adjustment of the bearing height so as to accommodate different interbody heights. In addition, the implant bone block accommodating hole is arranged on part of the lumbar interbody fusion cage so as to reduce the weight of the lumbar interbody fusion cage and improve the comfort level.
For the lumbar interbody fusion cage with bone grafting holes, which is expandable as described in CN203749649U, it has the following problems during installation and use: the implanted bone pieces are easily exposed/overflowed, have poor comfort during use, and are difficult to ensure that the implanted bone pieces are tightly packed in the bone grafting holes.
In addition, the stability of the expandable intervertebral fusion device after expansion is directly related to the comfort of a patient in the use process, and it is very important to ensure the stability and reliability of the lumbar intervertebral fusion device after adjustment. Because the intervertebral fusion device is supported by means of the supporting piece (such as a connecting piece) after being expanded, the structure of the intervertebral fusion device can be greatly simplified and the weight and the manufacturing cost of the intervertebral fusion device can be reduced by adopting the single connecting rod, but the biggest disadvantage of the single connecting rod is poor stability, so that the two cannot be simultaneously taken into account. Thus, how to ensure the stability of the intervertebral fusion device after expansion in a single-link support structure is a technical problem to be solved in the art.
