Clutch part A is made up of front end guide part and rear side body；Described part A front end guide part dorsal part oriented two
The draw-in groove of side opening, body dorsal part middle You Ban garden cylindricality lead, dorsal part rear portion two on rear side of described part A
There is the draw-in groove of upward opening side.There are card, described B in guide part veutro both sides, described fusion device part B front end
You Ban garden cylindricality direction recess in the middle of body veutro on rear side of part, there is the elastic card under backward both sides, veutro rear portion
Sheet.
Described fusion device A, part B width are 6mm, length 23mm, highly have 4.5mm, 5.5mm, 6.5
Mm, after assembling, height is respectively 9mm, 11mm, 13mm and (requires that service aisle internal diameter is respectively 7.5mm
、8.5mm、9.5mm)。
Compared to existing technology, the beneficial effects of the present invention is:
Matched handle, by using fusion device separable assembled to design, in use, can be contacted by the present invention
Formula grips fusion device A, B two parts, and intervertebral spinal fusion mirror, MED working tube hammer intervertebral space, work as A
It is partially into intervertebral space and after rear end goes out working column, turning handle 180 degree, make A, B two parts phase up and down
It is assembled in intervertebral space hammering, it is achieved after under MED or foramen intervertebrale lens, spinal canal decompression, intervertebral process,
Through working tube interbody fusion, form real Wicresoft's intervertebral fusion technology.

Detailed description of the invention
Below, in conjunction with accompanying drawing and detailed description of the invention, the present invention is described further, in order to more clear
The understanding present invention technical thought required for protection of Chu.
As shown in Figure 1, 2, 3, for a kind of assembled minimally Invasive lumbar fusion device of the present invention, including being provided with dorsal part
Front bayonet slot 13, rear draw-in groove 15, the part A 1 of middle lead 14 and be inserted into part A 1 dorsal part be provided with veutro
Front card 21, rear card 23, the part B 2 of middle gathering sill 22；Described part A front end guide part dorsal part is oriented
The draw-in groove 13 of both-side opening, card front of the slot has front catch 16, in order to card before the guide part of part B 21 interlocking,
And stop part B sliding forward；You Ban garden cylindricality segmentation lead 14 in the middle of described part A body dorsal part, with B
In the middle of part body veutro, half garden cylindricality gathering sill 22 matches, to guide part B 2 accurately to assemble with part A 1,
And mutual interlocking；There is the rear draw-in groove 15 of upward opening dorsal part both sides, described part A body rear end, in order to B portion
Divide card 23 phase interlocking after the two-side elastic of veutro rear portion.
Preferably, described fusion device has A, B two parts, in order to fusion device is divided into two parts through less
Working tube reaches intervertebral space, is assembled into the Invasive lumbar fusion device closing symbol requirement for height at intervertebral space.Fusion device A, B
Two parts are body hollow both sides porous, it is simple to fill bone material and osteogenesis merges.
Preferably, described fusion device part A 1 dorsal part has axial half garden cylindricality segmentation lead 14, lead
Front end is positioned at fusion device guide section and extends to forward the upslope 12 of lower reduction forward on rear, with fusion device
Guide part downslope 11 constitutes bullet-headed, it is simple to enter intervertebral space；Extend to both sides and form front bayonet slot 13,
So that with card 21 phase interlocking before fusion device part B, stop part B 2 forward, upwards, to both sides deviate from.Half
, after part A 1 enters intervertebral space, there is intervertebral pulling effect cylindricality lead 14 posterior segment, garden, opens for part B 2
Begin to enter intervertebral space headspace；Part A 1 dorsal part lead 14 also matches with part B veutro gathering sill 22,
Part B 2 can be guided accurately to move forward at part A 1 dorsal part, successfully assemble；Part A 1 dorsal part lead 14 after assembling
Interlocking mutual with part B veutro gathering sill 22.
Preferably, dorsal part both sides, described fusion device part A 1 rear end have the rear draw-in groove 15 of opening upwards, in order to
With part B 2 veutro rear portion two-side elastic card 23 phase interlocking, part B 2 is stoped to retreat abjection；Card slot rear wall sinks
Fall design, it is simple to part B 2 starts to slide to part A 1 dorsal part.
In use, by fusion device A, part B 1,2 is serially connected is fixed on matched handle 3, A portion
Before dividing 1 after part B 2；User holds handle 3, and by working tube 4, fusion device is sent to intervertebral space edge,
With hammer hammering handle rear end 31, fusion device part A 1 is hammered intervertebral space；Bar is fixed with fusion device part A
32 is axle, turning handle 3 about 180 degree, makes fusion part B 2 go to fusion device part A 1 opposite face,
Still with hammer hammering handle rear end 31, fusion device part B 2 is hammered intervertebral space, or thrust nut is tightened in combination
33, promote fusion device part B 2 with gathering sill 22 along fusion device part A lead 14 sliding forward,
Rear fusion device part B 2 assembles with fusion device part A 1, the forward and backward card 21,23 of fusion device part B
And draw-in groove 13,15 and lead 14 interlocking before and after gathering sill 22 and fusion device part A 1.
Above-mentioned embodiment is only the preferred embodiment of the present invention, it is impossible to limit the protection of the present invention with this
Scope, the change of any unsubstantiality that those skilled in the art is done on the basis of the present invention and replacing
