Description
Technical field
The present invention relates to a kind of orthopaedics and use medical apparatus and instruments, fusing device between specifically a kind of spinous process of treating human spine's disease.
Background technology
We know that in the operation of infra lumbar vertebral posterior, lumbar diskectomy, bone-graft fusion are aided with the common method that internal fixation has become treatment lower lumbar spine degenerative disease.Decompression completely is the successful key of operation with bone property fusion reliably, is the important means that obtains firm bone property fusion and be aided with internal fixation.Merging between spinous process is to be aided with internal fixation between spinous process through bone grafting between spinous process, to recover an integration technology of corresponding sections stability.Cobey had designed fusion device Wilson plate between first spinous process in 1971, and was successfully used to treat spine disorderses such as tuberculosis of spine, fracture of cervical vertebra.Document shows that merging between spinous process not only to increase the fusion area of lumbar vertebra, and then has increased the stability that merges sections, and operation technique is simple, goes out advantages such as insufficiency of blood.The inner fixer that is adopted is various, because the form of various inner fixers is different, structure is different, all has very high specificity again, and certain limitation is all arranged in clinical practice.Traditional is fixing, the operation technique grain granite, and operation wound is big, and is non-converged fixed mostly, influence operation syncretizing effect.At present cervical arc root screw internal fixing system (PS) is the most commonly used, but exists operation to appear shortcomings such as risk, the operating time of complicated, nerve root and dural sac damage be long.
Summary of the invention
Technical problem to be solved by this invention is the deficiency that overcomes above-mentioned prior art, provides a kind of rational in infrastructure, easy for installation, uses reliably, and is simple to operate, and safety is little to the wound of body, fusing device between the spinous process of realizing on the fixed basis merging.
The technical scheme that the present invention solves the problems of the technologies described above employing is: fusing device between a kind of spinous process; Comprise main fixing head, secondary fixing head, jackscrew; It is characterized in that: said main fixing head is positioned at a side of two adjacent spinous, which is provided with protruding connection fusant, and said connection fusant inserts the cylinder mould that interspinal part is a hollow; Bone implant is housed in the cylinder mould; Secondary fixing head is positioned at the opposite side of two adjacent spinous, which is provided with one be connected the fixing hole that installing hole and that fusant is complementary cooperates with jackscrew, secondary fixing head through jackscrew be connected fusant and be locked; The spinous process and the vertebral plate of said main fixing head and secondary fixing head and applying match.
The face that main fixing head according to the invention and secondary fixing head and spinous process are fitted is provided with tapered locking pin.Can penetrate the spinous process both sides after the pressurization, realize interspinal fixing.
Installing hole one side is provided with a boss on the secondary fixing head according to the invention, which is provided with the fixing hole that cooperates with jackscrew, and the face that connects corresponding fixing hole on the fusant is the flank of tooth, secondary fixing head through jackscrew be connected the fusant flank of tooth and lock fixing.
The installing hole of secondary fixing head according to the invention is provided with the gap with being connected between the fusant on secondary fixing head length direction, form 0 ~ 8 ° adjustment angle between main fixing head and the secondary fixing head.Like this, the spinous process of main fixing head and secondary fixing head and different-thickness or different angles can better be fitted.
When the present invention uses, between the pathological changes spinous process, punch, insert the connection fusant on the main fixing head between spinous process from spinous process one side, install to main fixing head to secondary fixing head from the spinous process opposite side again and connect fusant, two fixing heads are fixed together through jackscrew locking.Inserting interspinal part on the main fixing head is the wire mesh cage structures of hollow, and bone implant is housed in the cylinder mould, helps merging between spinous process.Main fixing head and secondary fixing head can be 0 ~ 8 ° angle, and the spinous process of fixing head and different-thickness or different angles can both better be fitted.Against existing technologies, the present invention is rational in infrastructure, and is easy for installation, uses reliably, simple to operate, and safety is little to the wound of body, can realize fixing and promotion fusion between spinous process effectively, is fusing device between a kind of ideal spinous process.
