Description

A kind of agnail formula Invasive lumbar fusion device of regulating and being with the vertebra steel plate that struts
Technical field
This utility model relates to medical instruments field, is a kind of agnail formula Invasive lumbar fusion device of regulating and being with the vertebra steel plate that struts.
Technical background
Along with average life span prolongation, traffic accident and motional injury increase, thus spinal column degenerated and traumatic case cumulative year after year, wherein needing operator, have more than the hundreds of thousands of them every year approximately.
Spinal operation is of a great variety, comprises decompression, the fixation that resets and orthopedic procedure etc.But every example operation postoperative all needs operation vertebra joint is merged, with the effect that obtains to stablize.Fusion in the past is based on from the body bone grafting, and not only the time long (about 3～June of bone time of fusion), getting bone because of need from its elsewhere of patient body increases patient suffering and complication.For this reason, there are various inner fixers to come out in recent years; In many inner fixers, Invasive lumbar fusion device has the advantage of its uniqueness, because of it places between two vertebras, not only contact surface is big, easily bone fusion, and can recover immediately vertebra joint highly and tension force, therefore society is then moved towards in postoperative patient's next day activity of can getting up 2～3 weeks.But presently used vertebra joint fusion device stability is relatively poor, easily outwards skids off or inwardly slips into and various complication occur, even cause paralysis, so that have to perform the operation once more.
Summary of the invention
This utility model provides the agnail formula Invasive lumbar fusion device of a kind of scalable and band vertebra steel plate, when implanting intervertebral space, because its unique agnail type design is embedded in fusion device between the vertebra joint earlier, screw in cone screw again, and vertebra is saved steel plate be fixed on the vertebra.Fusion device being strutted and increasing its stability simultaneously, also strengthen the constant intensity of fusion device, and can recover the height and the physiology curvature of vertebra joint effectively.
This utility model is by the hinge agnail formula fusion device 1 of band vertebra steel plate and strut screw 2 two parts and constitute.Described hinge-type fusion device 1 rear end is that hinge type or continous way connect one, front end and be and fit tightly two pages up and down, and is connected with a side or bilateral vertebra steel plate 13.Hinge agnail formula fusion device 1 body central authorities have for the oval defective region 2 of placing plant bone mass, the entity for playing a supportive role around the fusion device.

The specific embodiment:
Following embodiment further specifies the present invention, is limited to content of the present utility model but can not limit.
It is a kind of agnail formula Invasive lumbar fusion device of regulating and being with the vertebra steel plate that struts that accompanying drawing 1-4 has described this utility model, and its hinge agnail formula vertebra joint fusion device 1 and cone screw 2 by band vertebra steel plate is formed.The hinge agnail formula vertebra joint fusion device 1 of described band taper profile steel plate can be can strut adjusting, be with one-sided vertebra steel plate hinge agnail formula vertebra joint fusion device (accompanying drawing 4-2) and can strut adjusting, band bilateral vertebra steel plate hinge agnail formula vertebra joint fusion device (accompanying drawing 4-1).
It is deltiod that the hinge agnail formula vertebra joint of band vertebra steel plate merges fusion device 1, its rear end connection, and front opening also is connected with the steel plate of a side or bilateral; The transverse diameter of fusion device is greater than anteroposterior diameter 1mm; Overlook the bone grafting hole 12 that there is an oval defective region in fusion device central authorities, account for the hinge gross area 30～50%, recommend 40%, be used to place plant bone mass, respectively there are two row's agnails 11 on the next door, described side respectively have two row's agnails 11 can be backward agnail 1111 or/and agnail 112 forward; The side-looking fusion device is the hinge shape of front openings, wherein a side hinge or both sides hinge link to each other with a vertebra steel plate (Fig. 1 or 2); The steel plate screw screw 17 that pair of parallel is arranged in steel plate tail end or upper/lower terminal, and there is the locking device steel plate screw to lock screw 15, face, fusion device central authorities (being the hinge opening part) both sides respectively have one with lockly to decide the cone screw hole of device or hold hole 16, diameter 2mm, the usefulness that supplies cone screw 2 to screw in and strut, and the double hole function of holding; The screw hole 14 that the oval eccentric shape of locking device is arranged above interior.Cone screw 2 length are less than fusion device 1 anteroposterior diameter 2～3mm; Front end is thick, and the rear end is thin; Make hinge agnail formula vertebra joint fusion device 1 front end of band vertebra steel plate strut (Fig. 4) gradually by strutting screw 2 screw-in fusion device deeps.
The hinge (fusion device portion) of the hinge agnail formula vertebra joint fusion device 1 of this band taper profile steel plate highly is 4～8mm, can be 4,6 or 8mm, single page then is 2～4mm, can be 2,3 or 4mm, the width of fusion device is 11～13, can be 11,12 or 13mm, length is respectively 10～12mm, can be 10,11 or 12mm; All with above-mentioned three kinds of specifications for well.Its four jiaos is circular or middle fillet.With the taper profile steel plate thickness of fusion device front end continuity be about 1.3mm, wide 9～11mm can be 9,10 or 11mm, long 11～13mm can be 11,12 or 13mm; In fusion device central authorities (being the hinge opening part) both sides 16 2 in parallel shape cone screw hole is arranged, can be used to hold the hole, and link to each other with locking device locking screw 15.Cone screw 2 can be that arachnoid (Fig. 3-1) and head are scalariform (Fig. 3-2), and length is 8～10mm, can be respectively 8,9 or three kinds of specifications of 10mm; Its diameter is that preceding thick back is thin, and point diameter is that 3～6mm can be respectively 3,4,5,6mm, totally four kinds of specifications; The rear diameter is 1.5mm; In use, earlier the two sides all there is the hinge-type fusion device 1 of agnail to be parallel shape and inserts target vertebra part, screw in cone screw 2 again; And screw one or both sides vertebra steel plate screwing, screw at last after the inspection position is satisfied and strut screw 2.So can make the fusion device front openings increase 1～4mm.This not only makes the agnail of fusion device upper and lower surface deeper thrust the vertebra deep and obtains braking and strut effect; And can recover vertebra immediately and save original height and physiology curvature (Fig. 4).
This Invasive lumbar fusion device is applied to cervical operation, also can be used for thoracic vertebra and lumbar vertebra after amplifying in proportion.
This utility model Invasive lumbar fusion device earlier to the target vertebra part decompression, embeds target vertebra part with the fusion device of corresponding specification in use afterwards under softened state.Fusion device element leading edge is parallel with vertebra joint leading edge, or lower slightly 1～2mm.And vertebra is saved steel plate be close to vertebral body the place ahead, afterwards supporting cone screw 2 is screwed in to the deep, reach desired depth, and obtain the predetermined effect that struts.Whether the agnail hinge-type vertebra joint fusion device of checking implantation at last is stable, and whether vertebra joint steel plate puts in place.After the satisfaction, lock cone screw, locking steel plate screwing more earlier.Require the fusion device of implantations stable, invariant position, slip forward or backward, and taper profile steel plate are docile etc. is standard.
This utility model provides a kind of hinge agnail formula that can effectively regulate, also had the Invasive lumbar fusion device that vertebra saves steel plate, and is not only reasonable in design, easy to use, and strengthens the useful effect of agnail by cone screw and vertebra joint steel plate.Both guaranteed that Invasive lumbar fusion device can not skid off forward and can not slip into backward, can recover vertebra joint height and physiology curvature again rapidly.
This utility model can be widely used in the spinal surgery clinical case, comprises cervical vertebra, thoracic vertebra and lumbar vertebra.
