Description
Technical field
This utility model belongs to orthopedic medical device technical field, particularly relates to a kind of anterior lumbar inner fixing device.
Background technology
Along with the increase of aged tendency of population degree, and the becoming younger of lumbar disc disease, degenerative lumbar scoliosis disease gets more and more.Because the degenerative disorders great majority of lumbar vertebra decline relevant with the stability of lumbar function sections, recent two decades carrys out the operative treatment of degenerative diseases of lumbar vertebrae mainly based on nerve decompression and structural remodeling, and structural remodeling is fixed as master with the fusion of lesion segment.In recent years, fix the complication such as rear Adjacent segment degeneration acceleration for avoiding Lumbar Fusion and avoid the forfeiture of lumbosacral region movable function, suitably strengthening the surgical technic of vertebra joint stability and non-fusion technology obtains good development with preservation spinal mobility.Lumbar vertebra non-fusion technology divides front pillar, center pillar and rear pillar three major types.Existing front pillar non-fusion technology usually use artificial intervertebral disk, artificial nucleus etc. invasive therapeutic modality, change the intervertebral disc of lumbar vertebra of regression, both are all to damage based on original intervertebral disc structure, belong to whole end property operation.But artificial intervertebral disc and artificial nucleus cannot substitute natural intervertebral disc of lumbar vertebra completely, and its clinical efficacy has very large uncertainty, therefore clinical practice is obviously limited.Therefore how by surgical intervention, change degeneration intervertebral disc to the impact of lumbar spine: A, sport dynamics etc., the basis retaining intervertebral disc makes its stress in lumbar vertebra motion reduce, promotion functions is restored to a kind of new treatment thoughts.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of anterior lumbar inner fixing device, by intervention means, support is set between the upper and lower two joint adjacent lumbar vertebrae of pathological changes lumbar vertebra, reduces the stress of pathological interspinal dish in spinal motion, maintain intervertebral height and the appropriate motor function retaining this sections intervertebral disc.
This utility model solves the technical scheme that its technical problem adopts: provide a kind of anterior lumbar inner fixing device, comprise fixing head, the rectangular strip of described fixing head, the front of two described fixing heads is connected respectively to before the two upper and lower adjacent joint lumbar vertebras of human lesion lumbar vertebra, the described fixing head back side is with sleeve pipe, described sleeve pipe is built with flexible rod, the two ends of described flexible rod are arranged in the sleeve pipe of two described fixing heads respectively, and one end and the corresponding sleeve pipe of described flexible rod are fixed, the other end can slide in the sleeve pipe of another fixing head.
Cushion block is equipped with in the front at described fixing head two ends, and described cushion block one side is connected with fixing head, the shape of another side and the matching form of human body lumbar vertebra.
The one side that described cushion block contacts with human body lumbar vertebra is with fixing thorn.
Described fixing head and cushion block are provided with through hole, and described through hole is equipped with screw, and described fixing head two ends are connected by screw before lumbar vertebra.
With rivet hole on described sleeve pipe, described sleeve pipe by installing rivet and flexible rod is fixed in rivet hole.
Described flexible rod KEEP material is made.
Described fixing head titanium alloy material is made.
Beneficial effect
The utility model has the advantage of, by Wicresoft's means, support is set between the upper and lower two joint adjacent lumbar vertebrae of pathological changes lumbar vertebra (L5-S1), reduces the stress of pathological interspinal dish in spinal motion, maintain intervertebral height and the appropriate motor function retaining this sections intervertebral disc.

Detailed description of the invention
Below in conjunction with specific embodiment, set forth this utility model further.Should be understood that these embodiments are only not used in restriction scope of the present utility model for illustration of this utility model.In addition should be understood that those skilled in the art can make various changes or modifications this utility model, and these equivalent form of values fall within the application's appended claims limited range equally after the content of having read this utility model instruction.
As shown in Figures 1 to 3, a kind of anterior lumbar inner fixing device, comprise fixing head 1, the rectangular strip of described fixing head 1, the front of two described fixing heads 1 is connected respectively to before the two upper and lower adjacent joint lumbar vertebras of human lesion lumbar vertebra, described fixing head 1 back side is with sleeve pipe 4, described sleeve pipe 4 is built with flexible rod 2, the two ends of described flexible rod 2 are arranged in the sleeve pipe 4 of two described fixing heads 1 respectively, and one end and the corresponding sleeve pipe 4 of described flexible rod 2 are fixing, the other end can slide in the sleeve pipe 4 of another fixing head 1.
Cushion block 6 is equipped with in the front at described fixing head 1 two ends, and described cushion block 6 one side is connected with fixing head 1, the shape of another side and the matching form of human body lumbar vertebra.
The one side that described cushion block 6 contacts with human body lumbar vertebra is with fixing thorn 7.
Described fixing head 1 and cushion block 6 are provided with through hole 8, and described through hole 8 is equipped with screw 3, and described fixing head 1 two ends are connected to before lumbar vertebra by screw 3.
With rivet hole 5 on described sleeve pipe 4, described sleeve pipe 4 is fixed by installation rivet in rivet hole 5 and flexible rod 2.
Described flexible rod 2 KEEP material is made.
Described fixing head 1 is made with titanium alloy material.
In actual use, this utility model inner fixing device is retaining the lumbosacral region front road non-fused design that the basis of lumbosacral region intervertebral disc structure is carried out, utilizing less invasive techniques to reach operation object.The exposed area that lumbosacral region front and L5-S1 intervertebral disc front portion separate naturally for iliac artery, is applicable to through abdomen Micro-operation.This new device is fixed on lumbar vertebra L5-S1 sections front by front road through the other center cutout of abdomen, minimizing operation wound can be reached, and make a large amount of middle-older patient on the basis that need not emit huge operation risk, the slight illness solved caused by Lumbar Intervertebral Disc Degeneration is dropped into less medical treatment.Simultaneously, this utility model is by the Wicresoft's non-fusion technology retained for the purpose of original intervertebral disc, and its main purpose is by reducing the stress of L5-S1 sections degeneration intervertebral disc in lumbar vertebra mass motion, maintaining intervertebral height and the motor function of this sections intervertebral disc of appropriateness reservation.
