The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Refer to Fig. 1 to Fig. 4, ring rod combination exterior fixation bracket of the present utility model, comprise six roots of sensation screw 1, two arc side plates 2, some metal bone needles 3 (in the present embodiment being 6), two vertical columns 4, slide post 5, adjusting nut 6, screw connection 7, contiguous block 8 and some lock screws 9, wherein:
Two arc side plates 2 divide abreast and stand in both sides, in the middle of arc side plate 2, have penetrating arcuate groove 22, and a side of arc side plate 2 is provided with scale 21 along arc length, 1 millimeter of every two adjacent graduation marks distance;
Vertical columns 4 is column type, and centre has cannelure 43, and two ends are equipped with the first boss 41, the first boss 41 that snap in arcuate groove 22 and radially have the first screw hole 410; By screw 1 is screwed in to the first screw hole 410, make two vertical columns 4 be separately fixed at the two ends of two arcuate grooves 22 of two arc side plates 2, thereby connect into a framework, as shown in Figure 1;
On vertical columns 4, have at least two and hold the first circular hole 42 that metal bone needle 3 vertically passes, also have and each the first circular hole 42 corresponding and orthogonal the first locking screw holes 44 one by one, lock screw 9 screws in the first locking screw holes 44, and metal bone needle 3 is fixing, obviously, the quantity of lock screw 9 is consistent with the quantity of metal bone needle 3, has and hold the hole that lock screw 9 penetrates on metal bone needle 3;
Slide post 5 two ends are equipped with the second boss 51 that snaps in arcuate groove 22, and this second boss 51 radially has the second screw hole 510; By screw 1 is screwed in to the second screw hole 510, slide post 5 can be slided along two arcuate grooves 22 of two arc side plates 2;
On slide post 5, have at least two and hold the second circular hole 52 that metal bone needle 3 vertically passes, also have and each the second circular hole 52 corresponding and orthogonal the second locking screw holes (not shown) one by one, lock screw 9 screws in the second locking screw holes, and metal bone needle 3 is fixing;
