Abstract
Vertebra fixer prosthese bonding structure, comprises laminating base plate, retainer ring, flexure strip, stator.When use, retainer ring is inserted in the gap in the middle of two joint vertebras, laminating base plate just, as for vertebra outside, is fitted on vertebra, by the aperture on stator, inserts vertebra fixer bolt.Compared with prior art, the utility model has the advantages that: laminating human vertebra shape, total is smooth, round and smooth, alleviates the inadaptable sense that uses vertebra fixer to bring to patient.
Description
Technical field
This utility model relates to vertebra fixer, specifically refers to vertebra fixer prosthese bonding structure.
Background technology
Along with the development of vertebra medical skill, the advantage of vertebra fixer is gradually by popular recognition and acceptance, and vertebra fixer is widely used in medical treatment.Vertebra fixer is used for treating the impaired serious situations of vertebra such as vertebra lateral bending, spondylolysis or spinal fracture, and vertebra fixer has rectification, supports the function of vertebra.
Vertebra fixer in prior art, consists of screw and fixed bar, and it is simple in structure, stable connection.This fixed connector head is nut, although be very firmly fixed in vertebra, because its shape is outstanding, and the vertebra of not fitting, bring very large misery to patient.
Summary of the invention
For the deficiencies in the prior art, this utility model provides a kind of vertebra fixer prosthese bonding structure, and it is outstanding that its object is to solve vertebra fixer nut shape, alleviates the sense of discomfort that vertebra fixer brings to patient.
For achieving the above object, the technical scheme that this utility model adopts is: vertebra fixer prosthese bonding structure, comprises laminating base plate, retainer ring, flexure strip, stator; Described laminating base plate two ends, correspondence has been provided with two slotted hole passages, for adjusting the diverse location of vertebra fixer screw.Described retainer ring is circular ring structure, and laminating vertebra is wrapped in outside laminating base plate; Flexure strip is the cylindrical structural that the corrosion-resistant material of elasticity is made, and flexure strip girth is slightly less than girth in retainer ring, and flexure strip is as in retainer ring.Stator is that elongate in shape is placed on retainer ring, and stator two ends open hole, for coordinating vertebra fixer screw to use.
As preferably, laminating base plate two ends are arcuate structure.
As preferably, the thickness of described flexure strip is 0.8 centimetre.
When use, retainer ring is inserted in the gap in the middle of two joint vertebras, laminating base plate just, as for vertebra outside, is fitted on vertebra, by the aperture on stator, inserts vertebra fixer bolt.
Compared with prior art, the utility model has the advantages that: laminating human vertebra shape, total is smooth, round and smooth, alleviates the inadaptable sense that uses vertebra fixer to bring to patient.
Brief description of the drawings
Fig. 1 is this utility model floor map.
Fig. 2 is this utility model side schematic view.
Detailed description of the invention
Vertebra fixer bonding structure as depicted in figs. 1 and 2, it by the base plate 1 of fitting, retainer ring 2, stator 3, flexure strip 4, form, laminating base plate 1 is through retainer ring 2, flexure strip 4 is as in the middle of retainer ring 2, stator 3 is as on retainer ring 2; Laminating base plate 1 half arc lengthy motion picture structures, two ends are respectively equipped with the strip through hole that length is identical, and laminating base plate 1 two ends are circular arc.Retainer ring 2 is cirque structure, and wherein one section of length of side is that the annulus width of 1 centimetre is greater than another section of length of side, and the width of wider portion is the twice of narrow portion partial width.The circular configuration that flexure strip 4 is made for the corrosion-resistant material of elasticity, its thickness is less than relatively narrow one section of retainer ring 2, and thickness is 0.8 centimetre.Stator 4 is rectangle structure, and two ends have manhole, for coordinating the bolt of vertebra fixer.
When use, by relatively narrow retainer ring 2 one section gap that is placed in two joint vertebras, relatively wide one section of retainer ring 2 is positioned at two joint vertebras outsides, and vertebra fixer bolt, by the strip through hole of the screwed hole of stator 3 and laminating base plate 1, is fixed on vertebra.Being fitted in completely on vertebra of laminating base plate 1, flexure strip 4 gives support force in the time that vertebra is movable.
Claims (3)
