Description

{Lumbar interspinous process fixation device}

BACKGROUND OF THE INVENTION 1. Field of the Invention [0002] The present invention relates to a spinal lumbar spine fixation device.

In general, the spine is made up of a plurality of bones connected by joints, and between each joint is a disc.

The spine of the above structure functions as a cushioning function and serves as a foundation of human activity, as well as posture of the human being, and plays an important role in protecting all internal organs.

However, such vertebrae are damaged or distorted due to external artificial factors, degenerative or abnormal postures, etc. In such a case, the nerve passing through the spinal canal is pressed to cause severe pain.

Surgical treatment of the above diseases has been greatly developed and the procedures (hernia resection, spinal disc resection, recalibration) and procedures related to the vertebral bone osteosynthesis, which are performed to simply relax the pressure of the nerve root, Is being utilized.

Recently, a non-fusion technique such as a posterior implant-type non-fusion technique, which takes the form of a prosthetic disc implanted by anterior approach or provides movement with a certain degree of stability, .

However, in the prior art, since most of the devices for fixing are formed of a medical titanium material, they have no elasticity, and therefore, they can not maintain a normal waist curve after fusion according to the shape of the device.

In addition, when the device is screwed to the spine, there is a problem that another spinal stenosis or instability occurs after several years since the load is concentrated on the part where the screw is stuck. In particular, when an impact is applied to the waist due to external factors, there is a problem that the device is damaged or buried in the spinal column.

In addition, in the prior art, since all the ligaments between the extremities are to be removed for the installation of the devices, there is a problem that the patient has a large influence after the procedure and can not be recovered.

In addition, as the correction of the chiropractic is made with a number of complicated instrument configurations, the procedure becomes complicated and precision is required, and problems such as a boom residue and an operation cost increase due to an excessive component are caused.

In order to solve the above-mentioned problems, Patent Document 1 discloses a prosthesis for lumbar interdental prosthesis in which a torsional spring is included as a fixation system for attaching to a spiral portion of a vertebra in KR1218809 B1.

That is, by adding flexibility to the prosthesis due to the torsion spring, it is possible to restore the motion pattern similar to the physiological motion pattern to the segment of the spinal column.

However, (Patent Document 1) discloses a structure in which a clip is provided at both ends of the torsion spring to engage with the pulleys, thereby connecting the two pulleys. That is, when three or more spin rods are to be connected, there is a problem that installation space can not be provided because the installation space of the clip is not secured.

In addition, it is required to secure a treatment space considering the overall size by installing the clip and the torsion spring in an assembled state, and it is necessary to adjust the length of the clip for fixation after the clip is inserted into the puller.

In addition, since the size and shape of the spinning wheel may vary depending on the age and the body specification, there is a problem in that clips of various sizes and shapes may be required.
