Description
Technical field
The present invention relates to medicine equipment articles for use field, more particularly to fusion device between a kind of vertebral plate.
Background technology
The diseases such as protrusion of lumber intervertebral disc, lumbar instability, lumber spondylolisthesis usually cause serious pain in the back, and patient needs to receive waist
Vertebra fusion is treated.At present, the fusion of adjacent vertebral is typically carried out in Minimally Invasive Surgery using Invasive lumbar fusion device, such as
CN101015477B " minimally Invasive lumbar fusion device ", or CN203555820U " the minimally invasive fusion device of lumbar vertebrae dypass ".
These above-mentioned fusion devices apply art using when be to be initially inserted into from head in the gap between two pieces of centrums,
By two intervertebral pullings, fusion device is fixed afterwards, utilizes the skeletal grain induced fusion in fusion device.
However, in some cases, this Invasive lumbar fusion device can not solve the serious unstable phenomenon of vertebra section, and this fusion
Device, which needs to strut adjacent vertebral, could be implanted into fusion device, and operation is also not very convenient.Even, it is sometimes necessary to which the position of operation is simultaneously
Non- is adjacent centrum, but the centrum being spaced, above-mentioned fusion device can not be applicable.It is clinically to adopt for these cases more
With vertebral plate rear surface skeletal grain bone grafting, due to existing without compression, bone grafting easily absorbs this method, and bone grafting grain is to be dispersed in shape
State, it is possible that displacement, causes spinal cord and neurotrosis.
The content of the invention
In order to solve the above problems, it is an object of the invention to provide fusion device between a kind of vertebral plate, and it is applied art conveniently, is applicable
Scope is wide.
The technical solution adopted in the present invention is：
Fusion device between a kind of vertebral plate, including connector, the head of the connector and afterbody are respectively equipped with joint face, described
Upper surface homonymy of the joint face with connector, the inner chamber for placing skeletal grain, the upper surface are provided between the head and afterbody
The fusion mouth of inner chamber is communicated with, the fusion mouth is between two joint faces.
As a further improvement on the present invention, the fusion mouth has two, and one of them is close to head, and another is close to tail
Portion, two fusion mouths between be provided with skeletal grain barrier flaps.
As a further improvement on the present invention, the skeletal grain barrier flaps are netted.
As a further improvement on the present invention, the head and afterbody are equipped with screw, and the screw is under connector
Surface is through to upper surface.
As a further improvement on the present invention, the lower surface of the connector is provided with counterbore, institute relative to the position of screw
Counter bore hole diameters are stated more than screw and concentric with screw.
As a further improvement on the present invention, the left and right side of the connector is provided with lateral through hole, the lateral through hole
Communication with cavity.
As a further improvement on the present invention, the length on the fusion opening's edge head and afterbody line direction is 3~5mm.
The beneficial effects of the invention are as follows：The present invention connects two pieces using positioned at joint face of the head with afterbody and in the same side
The vertebral plate same surface of different centrums, the skeletal grain of induction is put into the lumen, skeletal grain is grown from fusion mouth to be melted with vertebral plate
Close, so as to complete the fusion of two vertebral plates, reach the purpose for the treatment of, because this fusion device is the same surface for connecting each vertebral plate, and
It is not to be implanted in intervertebral, can be applied not only to the fusion of adjacent vertebral, moreover it is possible to adapts to the fusion between the centrum of interval, and apply
Art is more convenient.
Brief description of the drawings
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is the axonometric schematic diagram of the present invention；
Fig. 2 is the axonometric schematic diagram at another visual angle of the present invention；
Fig. 3 is fusion device use state diagram between vertebral plate；
Fig. 4 is another use state diagram of fusion device between vertebral plate.
Embodiment
Fusion device between vertebral plate as depicted in figs. 1 and 2, including connector 1, connector 1 have upper surface, bottom surface, two
Side and two end faces, connector 1 also have head 2, afterbody 3 and the middle part between head 2 and middle part.Described head
Portion 2 and afterbody 3 are respectively equipped with joint face 4, and two joint faces 4 are located on the same side with the upper surface of connector 1, these connections
Face 4 is used to be connected and fixed on the surface that vertebral plate is located at the same side, as shown in Figure 3.The middle part of connector 1, which is provided with, places induction bone
The inner chamber of grain, the upper surface of connector 1 are communicated with the fusion mouth 5 of inner chamber, and fusion mouth 5 is between two joint faces 4.
The skeletal grain of induction is inserted when applying art in the lumen, the joint face 4 of head 2 and afterbody 3 is connected to difference
Vertebral plate be located at the surface of the same side, use the fixed component of outside to fix afterwards, then skeletal grain melts by merging mouth 5 with vertebral plate
Connection is closed, reaches the purpose of vertebral plate fusion.
For further preferred embodiment, as shown in figure 1, fusion mouth 5 there are two, arrangement is gone to upper and lower, one of them is leaned on
Nearly head 2, another connects two pieces of different centrums respectively close to afterbody 3, two joint faces 4.It is provided between two fusion mouths 5
Skeletal grain barrier flaps 6.The skeletal grain barrier flaps 6 are overlying on surface of internal cavity, the sky that can prevent skeletal grain from being fallen into from inner chamber between two centrums
Gap, avoid the ill effect caused by skeletal grain compressing spinal cord.
Preferably, skeletal grain barrier flaps 6 are netted that the aperture of mesh should be less than the size of skeletal grain.With flat barrier flaps
Compare, netted skeletal grain barrier flaps 6 have mesh, and induction skeletal grain can also grow from mesh and be connected between two centrums.
