Abstract
The utility model provides an interbody fusion cage, including merging the ware body, merge the ware body and include upper surface, lower surface, preceding terminal surface, rear end face, left surface and right flank, fuse ware body from the top down and set up the vertical cavity that is used for the bone grafting, its characterized in that, be equipped with two at least vertical baffles in the cavity, the baffle will the cavity falls into a plurality of independent cavities, after following, left surface and right flank has opened positioning channel section forward respectively, still be equipped with developing materials on the integration ware body. The utility model discloses an it makes integration ware bulk strength obtain the assurance to set up the baffle to can reduce effectively to merge the ware body the width, reduce holistic volume, so as to conveniently implants the intervertebral, reduces the destruction to the backbone tissue in the height of keeping the intervertebral crack.
Description
Technical field
This utility model relates to spinal operation medical apparatus and instruments, particularly relates to a kind of Invasive lumbar fusion device.
Background technology
At present, diversified Invasive lumbar fusion device enters field of spinal surgery in succession, has played important effect, be subject to the high praise of increasing spinal column section doctor in the success rate improving interbody fusion.Interbody fusion chief surgical step is as follows: intervertebral process and soleplate process; Determine bone grafting after fusion device specification; Implant fusion device; Nail-stick system is coordinated to complete operation.Fusion device width is in the market comparatively large, needs to destroy comparatively greatly spinal tissues before implantation, needs comparatively great strength to knock, implant more difficult, and be unfavorable for commitment intervertebral fusion during implantation.
Utility model content
It is less that the technical problems to be solved in the utility model is to provide a kind of overall volume, effectively ensures operation safety, reduces the Invasive lumbar fusion device destroyed spinal tissues, to overcome the defect in prior art.
In order to solve the problems of the technologies described above, this utility model adopts following technical scheme: a kind of Invasive lumbar fusion device, comprise fusion device body, fusion device body comprises upper surface, lower surface, front end face, rear end face, left surface and right flank, described fusion device body offers the vertical cavity for bone grafting from top to bottom, it is characterized in that, at least two vertical dividing plates are provided with in described cavity, described cavity is divided into multiple independently chamber by described dividing plate, described left surface and right flank have locating groove from back to front, described fusion device body is also provided with developing materials.
Preferably, described developing materials are tantalum wires.
Preferably, to be respectively equipped with multiple anti-back protruding for the upper surface of described fusion device body and lower surface.
Further, described anti-back is protruding all to described rear end face lopsidedness.
Preferably, described rear end face has screwed hole.
As mentioned above, this utility model Invasive lumbar fusion device, has following beneficial effect:
This utility model makes fusion device bulk strength be guaranteed by arranging dividing plate, thus effectively can reduce the width of fusion device body, the volume of reduction entirety, thus conveniently can implant intervertebral, the destruction to spinal tissues is reduced while the height maintaining intervertebral space, remove root compression, prevent Cage subsidence, finally realize vertebral fusion.

Detailed description of the invention
The structure that Figure of description illustrates, ratio, size etc., content all only in order to coordinate description to disclose, understand for person skilled in the art scholar and read, and be not used to limit the enforceable qualifications of this utility model, therefore the not technical essential meaning of tool, the adjustment of the modification of any structure, the change of proportionate relationship or size, do not affecting under effect that this utility model can produce and the object that can reach, all should still drop in scope that technology contents that this utility model discloses can contain.Simultaneously, quote in this description as " on ", D score, "front", "rear", the term such as " centre ", also only for ease of understanding of describing, and be not used to limit the enforceable scope of this utility model, the change of its relativeness or adjustment, under changing technology contents without essence, when being also considered as the enforceable category of this utility model.
As shown in Figure 1-Figure 3, a kind of Invasive lumbar fusion device of this utility model, comprise fusion device body 1, fusion device body 1 comprises upper surface 11, lower surface 12, front end face 13, rear end face 14, left surface 15 and right flank 16, described fusion device body 1 offers the vertical cavity for bone grafting from top to bottom, at least two vertical dividing plates 2 are provided with in described cavity, described cavity is divided into multiple independently chamber 17 by described dividing plate 2, described left surface 15 and right flank 16 have locating groove 18 from back to front, described locating groove 18 is for coordinating assigned address fusion device being sent to intervertebral with means of delivery.Described fusion device body 1 being also provided with developing materials 3, determining the position of fusion device when performing the operation in human body by developing materials 3.Preferably adopt tantalum wire as developing materials 3 in the present embodiment.Through verification experimental verification, described dividing plate 2 arranges two, and dividing plate 2 too much can affect bone grafting amount, the intensity that impact that I haven't seen you for ages is excessively overall.
After implanting intervertebral to prevent fusion device, position is unstable, and even easily displacement is deviate from, and as shown in Figure 1, the upper surface 11 of described fusion device body 1 and lower surface 12 are respectively equipped with multiple anti-back projection 19.Further, because fusion device implants intervertebral gradually from front end face 13 side, therefore described anti-back protruding 19 is all to described rear end face 14 lopsidedness, prevents from deviating from backward.
In order to the means of delivery making this fusion device stable is connected, the rear end face 14 of described fusion device body 1 has screwed hole 141, described screwed hole 141 can be threaded with means of delivery, and means of delivery and this fusion device can be made during operation to form one.After fusion device is in place, it is separated with fusion device by rotational conveyance instrument.
Because early stage stable of spinal column relies on fusion device to support, so the intensity of fusion device must ensure, the cavity on fusion device body 1 is divided into multiple chamber 17 by dividing plate 2 by this utility model, and dividing plate 2 plays the effect increasing bulk strength.In addition, had the guarantee of dividing plate 2 pairs of intensity and toughnesses, the distance (i.e. fusion device width) between fusion device left surface 15 and right flank 16 can effectively reduce, thus reduces the tractive equivalent damage to spinal tissues, increases the safety of operation.Through verification experimental verification, multiple chamber 17 is also conducive to impaction bone grafting granule.
In sum, this utility model Invasive lumbar fusion device, can effectively reduce overall volume size, increases the safety of operation.So this utility model effectively overcomes practical problems more of the prior art thus has very high value and use meaning.
Above-mentioned embodiment is illustrative principle of the present utility model and effect thereof only, but not for limiting this utility model.This utility model also has many aspects can improve under the prerequisite of overall thought, all without prejudice under spirit of the present utility model and category, can modify above-described embodiment or change for person skilled in the art scholar.Therefore, such as have in art and usually know that the knowledgeable modifies or changes not departing from all equivalences completed under the spirit and technological thought that this utility model discloses, must be contained by claim of the present utility model.
