Description

Vertebra device for spreading

Technical field

A kind of device for spreading of the utility model system, it is espespecially a kind of to treat that patient's intervertebral is narrow and disc disease, and can hold The vertebra device for spreading of compressed, stretching and twisting action.

Background technique

The spinal disease rate of modern has significant increase with busy work and inertia posture, and spinal disease packet Include: the narrow connective tissue with interverbebral disc of intervertebral is abnormal etc.；However these exceptions be likely to result in vertebra gap is excessive or mistake It is small, so that the stability of vertebrae is insufficient, cause adjacent vertebrae actuation exception or surface mutually to be worn, and patient is caused to carry on the back Portion or the comprehensive related pain of body, therefore spinal disease usually influences the daily life of patient.

It please refers to shown in Figure 10, only, systems stabilisation between known spine, including a top 60 and a lower part 80, the top 60 And the lower part 80 is respectively provided with a pair of of lateral sidewall 90, and a U-shaped middle part 70 is extended to form between the top 60, the lower part 80； However compressed action is only done at the middle part 70 of systems stabilisation between existing spine, does not have stretching, torsion and spring function, there are no shiftings Except the design of system, therefore systems stabilisation is set compared with what is disposed after the behavioral aspect and medical treatment for not meeting human-body biological between existing spine Meter.

So, systems stabilisation can reach preliminary treatment between known spine, but often cause and skeleton knot because rigidity is too strong Situations such as fracture occurs at conjunction or loosens.

In view of this, creator's sheet is in the manufacturing development and design experiences of being engaged in Related product for many years, for above-mentioned mesh Mark designs in detail and after discretion assessment, obtains the utility model for really having practicability eventually.

Utility model content

The purpose of this utility model is to provide a kind of vertebra device for spreading, it is to be solved the problem of, be directed to habit Systems stabilisation can only provide compressed action between knowing spine, not have stretching, torsion function, cause the limitation spinal motion of patient and more To active force, so problem need to be improved breakthrough.
