Description
Technical field
The present invention relates to spinal interbody fusion field more particularly to a kind of minimally invasive fusion devices.
Background technique
Backbone degenerative disease and its structural damage are to cause human necks, shoulders lumbocrural pain, feeling and motor function impaired very
To a major reason of forfeiture.The fifties in last century, Cloward propose posterior lumbar fusion process (PLIF), the technology first
Develop into one of basic art formula of current spinal surgery.Badgy and Kuslich in 1986 is designed to be melted suitable for the intervertebral of human body
Clutch (Cage), i.e. BAK system.Hereafter, Intervertebral fusion technology has large development, becomes treatment backbone degeneration disease
A kind of basic operative mode of disease and structural damage.
The principle of Invasive lumbar fusion device is centered on pathological interspinal gap, and after being implanted into Invasive lumbar fusion device, distracting force makes to merge
Muscle, fibrous ring and the forward and backward longitudinal ligament of segment are under continued tension state, and Fusion levels and fusion device is made to reach three-dimensional super
Statics is fixed.Secondly, Invasive lumbar fusion device is by restoring the height of intervertenral space, with before restoring backbone, the stress of center pillar and stabilization,
Restore, maintain the intrinsic physiology protrusion of backbone, expands intervertebral foramen, alleviate the compression of dural sac, nerve root.Invasive lumbar fusion device it is hollow
Structure provides good mechanical environment for the fusion of the cancellous bone in it, to achieve the purpose that interface permanent fusion.
Existing routine fusion device is generally a series of case structure of fixed shapes, adapts to by a series of height models
Different interbody spaces can not be matched with the intervertenral space of sufferer completely；And in order to reach good support effect, branch when design
Support face need to be big as far as possible, and also larger so as to cause implantation channel, larger to patient trauma, post-operative recovery is slow.
Such as publication CN105380735A discloses a kind of intervertebral filling fusing device i.e. application method, for filling out
Enter between the adjacent terminal plate of vertebral body of any two of human body lumbar vertebrae, the intervertebral filling fusing device includes accommodating member, is set to institute
The reticulate body of accommodating member periphery is stated, the first filling with self-solidifying solidity is packed between the accommodating member and the reticulate body
Object.But to being packed into the first filler with self-solidifying solidity between the accommodating member and the reticulate body when design use,
Reticulate body expands that shape out is uncontrollable, causes to be unable to control with the contact area of upper hypocentrum so that bone grafting region it is too small and
Influence vertebral fusion effect up and down.
If publication CN206852685U discloses a kind of bone fusion device, the bone fusion device include cuff components and
Mesh bag, the cuff components include: inner sleeve；Outer tube；Outer ejector sleeve, the outer tube are located in the outer ejector sleeve；Tying machine,
The tying machine is placed in the front end of the outer ejector sleeve, and the outer bushing surface described in the outer ejector sleeve effect lower edge is mobile；It is described
Mesh bag is provided with mesh on surface.But the design fusion device withdraws from core needle, during bone grafting, with net after entering intervertenral space
The expansion of bag is bound to cause mesh bag head end retraction, and position is not inconsistent with predeterminated position after causing fusion device to be implanted into；And the fusion device exists
It needs to seal fusion device mesh bag with tying machine after the completion of bone grafting, increases the operating procedure of operation.
For another example, it has been disclosed that a kind of expansible Invasive lumbar fusion device of patent CN104783935A, including by two expansion block splits
The outer housing of composition, it is characterized in that: being cavity structure in the outer housing, inside is equipped with leading truck and position-limited rack；The limit
Frame upper end is placed in the inside casing top of leading truck and is connect by screw with leading truck, the dislocation inclined-plane and guiding that middle part passes through two sides
Frame fitting；Frame bottom in position-limited rack is fixed in the leading truck lower part.Although mechanism height can be raised, width direction does not have
There is scalability, if will be by the elongated work channel of endoscope, be bound to narrower width, and length is limited by centrum size
System, the area finally contacted with upper and lower soleplate is smaller, causes centrum local pressure excessive, causes fusion device to sink down into vertebra for a long time
Internal portion.
It can be seen from the above, some fusion devices do not have good mechanical support power in the operation of existing intervertebral fusion, need
It inserts self-solidifying material and reaches mechanical support purpose, it is bad to frequently result in surgical effect from the amorphous state of gel material, in turn
It needs to carry out second operation, brings heavy burden to patient；Minimally invasive fusion device in existing patent is in terms of mechanical structure
The variable or width direction variable of short transverse can only be often realized, both in terms of elevated height and centrum contact area
It can not be compatible with, and mechanical structure limits bone grafting space, influences syncretizing effect；In addition, employed in intervertebral fusion operation at present
Fusion device be mostly fixed form bulk, volume is larger, when implantation need it is biggish enter channel, sufferer damage is larger.
