The specific embodiment
See also shown in Figure 1ly, it is to be the first preferred embodiment element decomposing schematic representation of the present utility model, wherein can see this utility model and comprise:
One holder 10, has a chase 12 that is the U font on it, this chase 12 is to pass for spinal fixed rod 30, be provided with relative catching groove 14 in inboard, chase 12 two side, be provided with the clip slot 16 that supplies tool holding in the outside, chase 12 two sides, the apical margin in chase 12 two sides is provided with the banking stop 18 of protrusion in addition;
One fixed block 20 is provided with the button edge 22 of protrusion around fixed block 20, the two opposite sides of this button edge 22 are provided with tangent plane 220, are provided with the compacting cambered surface 24 of protrusion in fixed block 20 bottom surfaces, and fixed block 20 end faces are provided with and revolve control and holds 26;
By shown in Figure 2, it is to be the first preferred embodiment fixed block, 20 bottom surface structural representations of the present utility model, wherein can see the structure of fixed block of the present utility model 20 bottom surfaces compacting cambered surface 24, direction at these compacting cambered surface 24 central parallel cut surfaces 220 is provided with an assembling cancave cambered surface 240, the direction of vertical assembling concave arc 240 is provided with a fixing concave arc 244, and at assembling concave arc 240 and fixedly be provided with adjustment concave arc 242 between the concave arc 244; It is the darkest wherein to assemble concave arc 240 degree of depth, and fixedly the degree of depth of concave arc 244 is the most shallow, and the degree of depth of adjustment concave arc 242 is between between the two.
It is to be an outer-hexagonal head end 260 that fixed block 20 in this embodiment revolves control end 26, is provided with a circle stopper slot 262 in its bottom surface.
Cooperate shown in Figure 2, it is to be first preferred embodiment combination sketch map of the present utility model, when this utility model in when combination, be earlier fixed bar 30 to be placed in holder 10 chases 12, then fixed block 20 is inserted in holder 10 chases 12, because 220 width of two tangent planes of fixed block 20 button edge 22 opposite sides are to match with the chase 12 of holder 10, and can allow fixed block 20 insert easily in holder 10 chases 12, insert when locating in the chase 12 at fixed block 20, the assembling concave arc 240 of its compacting cambered surface 24 abuts on the fixed bar 30, and the position that makes its button edge 22 just aligns the catching groove 14 of holder 10, promptly can be rotated fixed block 20 through revolving control end 26 by proper implements this moment, after fixed block 20 rotations, can allow button edge 22 buckle in holder 10 catching grooves 14, and suppress by compacting cambered surface 24 pairs of fixed bars 30, when fixed block 20 rotates to when adjusting concave arc 242 and reclining fixed bar 30, fixed bar 30 slightly is pressed, but do not reach the fixed degree of packing yet, so operator still can make fixed bar 30 suitable position adjustment, and after fixed bar 30 is adjusted to the location, fixed block 20 can be remake rotation, and fixing concave arc 244 fixed bar 30 that reclines of order makes fixed bar 30 be clamped in holder 10 chases 12 and fixed block 20 fixedly (as shown in Figure 4) between the concave arc 244 by firm.
In addition in Fig. 4, can see fixed block 20 of the present utility model and be assembled into when locating in holder 10 chases 12, be arranged on the stopper slot 262 that fixed block 20 revolves control end 26 bottom surfaces and can be set in holder 10 banking stops 18 outsides, and another part retention effect is provided again.
Next by shown in Figure 5, it is to be the second preferred embodiment element decomposing schematic representation of the present utility model, the overall structure configuration that wherein can see this embodiment is identical with aforementioned first embodiment, but the control of revolving of this fixed block 20 holds 26 to be a hexagon socket head end 264, simultaneously on the holder 10 of this embodiment, do not have banking stop 18, on fixed block, also do not have stopper slot 262.
Cooperate this utility model second preferred embodiment of Fig. 6 to make up shown in the sketch map, the structure of this embodiment is identical with aforementioned first preferred embodiment in use, but because this embodiment will revolve the design of control end 26 employing hexagon socket head ends 264, so the height after combination can being finished is reduced to lower degree, and can allow whole shared space still less.
Holder in aforesaid two embodiment can one-body moldedly have fixed screw 17 (as shown in Figure 6) 10 times, also can arrange in pairs or groups as No. 81216259 [vertebra hook clamping is decided resetting means] (U.S.Pat.5,439,463) hook shown in presss from both sides and uses, and brings into play the effect of its practicality.
Again by shown in Figure 7, it is the embodiment element decomposing schematic representation for the first preferred embodiment adaptation arrangement of the present utility model, 40 utilizations, by shown in the figure as can be known, this utility model also can be provided with hinge device 40 below holder 10, it is to form hole seat 19 below holder 10, and a fixed screw 42 with bulb 420 can be assembled in the hole seat 19, and 420 tops of the bulb in holder 10 assembling, one compacting ball 422, when fixed bar 30 is assembled in holder 10 chases 12, this fixed bar 30 can abut in bad 422 tops of compacting, and suppress bulb 420 by compacting ring 422, therefore, can allow and fix 30 and be line with 422 on compacting ring and contact, and the point-like that more known this type of hinge device is directly suppressed bulb with fixed bar contacts more firm.
Shown in Fig. 8, it is combination cross-section structure configuration schematic diagram for first preferred embodiment collocation hinge device of the present utility model, 40 utilizations, wherein as can be seen this utility model with the assembling completion status of holder 10 collocation hinge devices utilization, they can be by fixed block 20 compacting fixed bars 30, suppress bulb 420 by fixed bar 30 via compacting ring 422 again, the overall structure collocation is perfect, really is an outstanding design.
Shown in Fig. 9, be to be the arrange in pairs or groups combination generalized section of another pattern hinge device 50 of first preferred embodiment of the present utility model, wherein can see the hole seat 19 that below this holder 10, is provided with a deflection, so it can assemble compacting ring 422 and bulb 420 by hole seat 19 belows collocation one assembling ring 52, so also can realize identical effect.
Again by shown in Figure 10, it is to be another preferred embodiment element decomposing schematic representation of the present utility model, its whole structure configuration is identical with first preferred embodiment shown in Fig. 1, but on this fixed block 20, a fixing threaded hole 28 can be set, and can be after fixed block 20 is assembled on the holder 10 location, a fixed screw 280 is screwed in fixed block 20 fixing threaded holes 28 again, and provide another part compacting fixation to fixed bar 30, allow whole fixed effect obtain multiple guarantee, bring into play better practicality.
All be the explanation of example work among the cited embodiment in above explanation and the accompanying drawing, but this utility model also can be used in the secure fit of spinal staple, and can reach identical immobilization efficiencies with fixed bar 30.
