example 1

[0045] Example 1: Expansion mode (simultaneous two-axis adjustment)

[0046] refer to Figure 4 and Figure 1C , the expansion mode of the example intervertebral fusion device 100 will now be described. In the expansion mode, the first drive mechanism 200 and the second drive mechanism 250 of the intervertebral fusion device 100 may operate simultaneously, thereby providing parallel expansion or contraction of the intervertebral fusion device 100 .

[0047] The intervertebral fusion device 100 in the starting or collapsed configuration may first be placed in the intervertebral space via an anterior surgical procedure. Starting in expansion mode, the user can use the Figure 2A to Figure 2C as well as Figure 3A to Figure 3D Surgical instrument 400 is shown including first driver 410 and second driver 420 , allowing first driver 410 to engage drive gear 314 of first gear assembly 310 and second driver 420 to engage first drive gear of second gear assembly 350 354, as in ...

example 2

[0053] Example 2: lordotic mode (independent front axle adjustment)

[0054] refer to Figure 5 and Figure 1C , the lordotic mode or independent anterior axis adjustment of the example intervertebral fusion device 100 will now be described. In this lordotic mode, the second drive mechanism 250 of the intervertebral fusion device 100 can operate independently of the first drive mechanism 100 to provide lordotic adjustment to the configuration of the intervertebral fusion device 100 at the anterior side 106 . The lordotic pattern of the interspinous fusion device 100 may be required to provide an expanded offset between the anterior side 104 and the posterior side 106 of the interspinous fusion device 100 . The anterior side 104 may expand and / or contract to a point below the posterior side 106, resulting in negative lordosis (kyphosis).

[0055] Beginning in the protrusion mode, the user may only extend the second driver 420 of the surgical instrument 400, thereby only allo...

example 3

[0060] Example 3: lordosis mode (independent rear axle adjustment)

[0061] refer to Figure 6 and Figure 1C, another lordotic mode or independent posterior axis adjustment of the example intervertebral fusion device 100 will now be described. In this lordotic mode, the first drive mechanism 200 of the intervertebral fusion device 100 can operate independently of the second drive mechanism 250 to provide lordotic adjustment of the configuration of the intervertebral fusion device 100 at the posterior side 104 . The posterior side 104 may expand to a point above the anterior side 106, resulting in negative lordosis (kyphosis).

[0062] Beginning in the protrusion mode, the user may only extend the first driver 410 of the surgical instrument 400, thereby only allowing the first driver 410 to engage the drive gear 314 of the first gear assembly 310, as Figure 3D shown in . In this lordotic mode, second first driver 420 of surgical instrument 400 does not engage first drive ...

Abstract

An intervertebral fusion device employs a torque transmitting mechanism to transmit torque to a drive mechanism responsible for expanding the intervertebral fusion device in a direction that is not parallel to a longitudinal axis of the drive mechanism.

Description

technical field [0001] The present disclosure generally relates to devices, systems and methods for treating spinal disorders. In particular, various embodiments of expandable and adjustable lordotic interspinous fusion devices are described. Background technique [0002] Spinal fusion is a surgical procedure to correct problems related to the human spine such as degenerative disc disease (DDD), spondylolisthesis, recurrent herniated disc, etc. Spinal fusion usually involves removing the damaged disc and bone from between adjacent vertebrae and inserting a bone graft material that promotes bone growth. Adjacent vertebrae join or fuse together as the bone grows. Fusing the bones together can help stabilize specific areas of the spine and help reduce problems associated with nerve irritation at the fusion site. Fusions can be performed at one or more levels of the spine. [0003] In intervertebral spinal fusion surgery, the nucleus pulposus and / or annulus fibrosus that mak...
