To or mutually from movement.
The present invention can strut fusion device, wherein the rod-shaped hollow hexagonal bottle opener, housing are close to the one end that can strut component
End is tapered.
The present invention can strut fusion device, if wherein perforate and surface are both provided in the middle part of the upper link block, lower connecting block
Dry double wedge offers several apertures in the interior hexagonal multi-hole connecting rod.
The present invention can strut fusion device, wherein the gripper jaw there are two and be clamped in one both sides of sliding block.
The present invention can strut fusion device by adjust rod-shaped hollow outer-hexagonal bottle opener can carry out upper and lower link block strut height
Adjusting, meet it is a variety of operation implantation desired heights so that a kind of fusion device have plurality of specifications, widened fusion device significantly
The scope of application greatly facilitates doctor's operation.Meanwhile above-mentioned bottle opener inside is hollow structure, can insert bone implant in due course,
Artificial bone is such as inserted, so as to preferably synchronous with the holding of the area of new bone speed of growth.It locks handwheel and is sleeved on outside gripping sleeve
Housing is convenient for the opening of gripper jaw on fusion device and is firmly grasped, and effectively improves the holding performance of fusion device, improves fusion device plant
Fashionable security, stability.In short, the fusion device that struts of the present invention has a better effect spinal disease, it is easy to operate,
Easy to use, fusion rate is high, and the complication of no bone grafting fusion can be widely applied to clinic.
The fusion device that struts of the present invention is described further below in conjunction with the accompanying drawings.

Specific embodiment
As shown in Figures 1 to 10, the present invention can strut fusion device and include holder 10 and be connected to 10 end of holder
Component 20 can be strutted.
Holder 10 includes rod-shaped hollow outer-hexagonal bottle opener 1, locking handwheel 2, gripping sleeve 3 and housing 4, gripping sleeve 3 and is placed on
Rod-shaped hollow outer-hexagonal bottle opener 1 is outer and left end is threadedly coupled locking handwheel 2, and right end end set has gripper jaw 31, to clamp
Component 20 can be strutted, in the present embodiment, gripper jaw 31 is set there are two pawl, is clamped in following one 5 both sides of sliding block.Housing 4 is coated on
Outside gripping sleeve 3, during rotation lock handwheel 2, gripping sleeve 3 can move left and right in housing 4 along housing 4 is axial.Specifically, initially
Under state, gripper jaw 31 stretches out open-shaped state outside housing 4, rotation lock handwheel 2, and gripping sleeve 3 moves in housing 4, with
The movement of gripping sleeve 3, gripper jaw 31 are gradually closed up by the extruding of housing 4, realize opening and the tightening of holder 10.Wherein, it is rod-shaped
Hollow hexagonal bottle opener 1, housing 4 are tapered close to the right end end that can strut component 20.
Component 20, which can be strutted, includes the interior hexagonal multi-hole connecting rod 7 being connected with rod-shaped hollow outer-hexagonal bottle opener 1.Also wrap
Include appearance be in isosceles trapezoid upper link block 6, lower connecting block 8, after upper link block 6,8 upper bottom surface of lower connecting block are close to each other with
Interior hexagonal multi-hole connecting rod 7 is disposed thereon lower both sides for minute surface symmetry axis.Upper 6 left and right sides of link block and lower connecting block 8
The left and right sides forms wedge shape space between interior hexagonal multi-hole connecting rod 7, and sliding block 1 is equiped in the wedge shape space of left side, right
Sliding block 29 is equiped in the wedge shape space of side.Between sliding block 1 and upper link block 6, lower connecting block 8 and sliding block 29 and upper company
It connects and is engaged between block 6, lower connecting block 8 by dovetail groove.Spiral shell between sliding block 1, sliding block 29 and interior hexagonal multi-hole connecting rod 7
Line connects and hand of spiral is on the contrary, so that sliding block 1, sliding block 29 can be axially opposite along interior hexagonal multi-hole connecting rod 7 or phase is from fortune
It is dynamic.Specifically, control slide block 1 is rotated by rod-shaped hollow outer-hexagonal bottle opener 1 and sliding block 29 slides in opposition towards centre, from
And link block 6, lower connecting block 8 is made to strut link block 6, lower connecting block along interior hexagonal multi-hole connecting rod two Slideslips about 7
8, height therebetween is made to be increased by the height h in Fig. 7 as the height H in Fig. 8, finally plays the work for strutting hypocentrum
With.Upper link block 6,8 surface of lower connecting block are both provided with several double wedges, for ensureing the stability after fusion device implantation.Meanwhile
Upper link block 6,8 middle part perforate of lower connecting block offer several apertures in interior hexagonal multi-hole connecting rod 7.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the model of the present invention
It encloses and is defined, on the premise of design spirit of the present invention is not departed from, those of ordinary skill in the art are to the technical side of the present invention
