Abstract
The utility model discloses a lumbar fracture diaplasis inner fixer which consists of connecting poles 1, 1.1, fixing nails 2, 2.1 and pulling poles 4, 4.1. The connecting poles 1, 1.1 are cylinder bodies which are provided with right inner threads and reverse inner threads, the two ends are connected with fixing poles 3, 3.1 of the fixing nails, the outer ends of the fixing poles 3, 3.1 are fixedly provided with the inflationary bolt fixing nails 2, 2.2, the connecting poles 1, 1.1 are connected by the pulling poles 4, 4.1. The utility model has the advantages that: the dynamics structure of the inner fixer is reasonable, the operation is convenient, the fixing is steady, the diaplasis effect is good and the utility model can be widely applied in the lumbar fracture reposition.
Description
This utility model relates to a kind of fracture reposition instrument, specifically a kind of lumbar vertebra fracture inner fixer that resets.
At present, in lumbar vertebra fracture resets, the pedicle of lumbar vertebra inner fixers of using short segment are fixed more, this holder is made of staple, connecting rod, because connecting rod is shorter, thus the little advantage of wound is arranged, but because connecting rod is shorter, so the infull shortcoming that resets is arranged, and phenomenon that occurs broken nail easily, follows closely loosening and disconnected bar.In order to improve the shortcoming that short segment pedicle of lumbar vertebra inner fixer exists, in recent years sequential use steel plate, annular knurl nail etc., but all there are shortcomings such as complex structure, inconvenient operation, power unreasonable structure in these products, big as STEFFEE steel plate pedicle screw and steel plate place shear stress, art light plate cover nail is difficult for grasping; The anti-rotation of Shen Shi pedicle of cervical vertebra fixture is poor, the unbalanced stress weighing apparatus; The annular knurl nail is prone to the center pillar damage in reseting procedure, the back fixation that resets lost efficacy sometimes.
The purpose of this utility model be to provide a kind of simple in structure, power is rational in infrastructure, easy to operate, fixation, lumbar vertebra fracture that the rotation of any orientation can not take place reset inner fixer.
This utility model is achieved in that this lumbar vertebra fracture inner fixer that resets, constitute by connecting rod, staple, its connecting rod is simplified, if positive and negative female thread, threaded one end is opposite with other end hand of spiral, two ends connect the fixed bar of going up staple, the fixed bar of staple is established external screw thread, be rotatably connected with the two ends female thread of connecting rod, the fixing staple of going up in the outer end of the fixed bar of staple, staple is a swell fixture, connecting rod connects with stayed pole, the stayed pole link is established external screw thread, is connected by the connecting cylinder of establishing positive and negative female thread.The fixed bar outer end of staple is a flat-square shaped, is provided with the installing hole of swell fixture staple, and the installing hole of its swell fixture staple is oblique screwed hole, and the stayed pole outer end is a collar, and the collar is enclosed within on the connecting rod.When using this utility model, staple revolved insert in the vertebral hole of accomplishing fluently rotation swell fixture staple, fixation, the bar that is rotatably connected again makes the staple tensioner, and the vertebra spreading makes one section of damage no longer pressurized, the tube that is rotatably connected again makes the connecting rod tension, thereby it is fixing to realize resetting.
Advantage of the present utility model is simple, easy to operate, fixation rational in infrastructure, rotation, the better reduction in any orientation can not take place.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is this utility model structural representation.
Fig. 2 is this utility model schematic side view.
Make this utility model with reference to accompanying drawing 1,2.This lumbar vertebra fracture inner fixer that resets, by connecting rod 1,1 ', staple 2,2 ' constitute, its connecting rod 1,1 ' be cylindrical shell, if positive and negative female thread, the fixed bar 3,3 of the last staple of two ends connection ', the fixed bar 3,3 of staple ' establish external screw thread, with connecting rod 1,1 ' female thread be rotatably connected, the fixed bar 3,3 of staple ' the outer end fixing go up staple 2,2 ', staple 2,2 ' be swell fixture, connecting rod 1,1 ' usefulness stayed pole 4,4 ' connection, stayed pole 4,4 ' link are established external screw thread, are connected by the connecting cylinder 5 of establishing positive and negative female thread.The fixed bar 3 of staple, 3 ' outer end are flat-square shaped, be provided with above swell fixture staple 2,2 ' installing hole, this installing hole is oblique screwed hole, stayed pole 4,4 ' outer end be a collar 6,6 ', the collar 6,6 ' be enclosed within connecting rod 1,1 ' on.
