The specific embodiment
Fig. 1 is this utility model overall structure sketch map, mainly comprises framework 1, support 2, fixed mount 3, linking arm 4 and angle demodulator 6.The two ends of support 2 are connected with framework 1 with fixed mount 3 respectively, and this framework 1 is the arc project organization, and the two ends of framework are respectively equipped with a plurality of through holes, and staple 5 is arranged in the inside of through hole, and the downside at framework two ends also is respectively equipped with fixing hole (not describing among the figure).Fixed mount 3 also is respectively equipped with linking arm 4 with the both sides of framework 1, these linking arm 4 whole undulate designs, square through hole that establish respectively at the two ends of linking arm and breach, breach is arranged in the outside of fixed mount, the thickness of square through hole one side is greater than the thickness of opposite side, this square through hole is fixedlyed connected with fixing hole by screw 14, thereby makes the outside of being fixed in framework of linking arm.The surface of fixed mount 3 is provided with through hole, and last extension rod 12 is arranged in the inside of fixed mount surface through hole, thereby makes angle demodulator 6 be arranged at the both sides of support 2 respectively and fixedly connected with fixed mount 3.In addition, the upside of framework 1 also is provided with steady rest 15, and this steady rest 15 is the arc project organization, and two ends are individually fixed in the framework both sides.Steady rest can increase the stablizing effect of framework integral body, thereby framework integral body can not become flexible because of casual the rocking of patient, has also improved stability and comfort when the patient wears.
Fig. 2 is this utility model adjusting device structural representation, mainly comprises angle demodulator 6 and scale bar 7.The top and bottom of angle demodulator 6 is provided with extension rod 12 and following extension rod 13, and the other end of following extension rod 13 is provided with through hole.Scale bar 7 is the flat structural design, and the surface of an end is provided with through hole, and the surface of dual-side also is respectively equipped with screw thread.The scale bar is arranged in down the through hole inside of extension rod one end, because the both side surface of scale bar is provided with screw thread, and the therefore purpose that can angle demodulator 6 and scale bar 7 be achieved a fixed connection by nut 11.In addition, be provided with turning cylinder (not describing among the figure) in the inside of angle demodulator 6, the surface also is provided with scale, scale and fixing hole 10.The quantity of fixing hole 10 is two, and perhaps more than two, fixing hole is the polygon project organization, and inner surface also is provided with helicitic texture.Scale is made up of numeral, thereby the turning cylinder by rotational angle actuator inside makes scale corresponding with the numerical value in the scale, by the screw in the fixing hole turning cylinder is locked then, the numerical value in scale and the scale can not departed from, further keep the accurate performance of data.
Fig. 3 is this utility model traction apparatus structural representation, comprises that mainly spring 8 and traction collude 9, and spring 8 and traction are colluded 9 and be memorial alloy and make, and the main material of this memorial alloy is a titanium-nickel wire.The maximum tension of spring is 1-5KG, and spring can be according to the change of temperature and reverted to the shape that configures at first gradually, stablizes persistent pull strength thereby super-elasticity that spring has and Memorability are formed.The two ends of spring 8 are respectively equipped with hook, and traction is colluded an end and is provided with hook ring, and is arranged in the inside of spring one end hook, is connected thereby spring is colluded with traction.In addition, draw the other end that colludes and also be provided with through hole.The traction complex temperature of colluding is between 20 ° ~ 40 °, thereby traction is colluded be easier to moulding.Therefore, the shape that also can keep relative stability after with its implant into body, and can reach the compatibility preferably with organizing also around the jawbone.
Fig. 4 is this utility model adjusting device and traction apparatus connection diagram, mainly comprises scale bar 7 and spring 8.Because the surface of scale bar 7 one ends is provided with through hole (not describing among the figure), and an end of spring 8 is provided with hook, the diameter of through hole is big or small identical with the hook diameter, and therefore, hook can be arranged in the inside of through hole, thereby scale bar 7 interconnects with spring 8.
In sum, the craniofacial bone bone traction apparatus that this utility model provides is when reaching adjusting pull strength size, the situation of also having avoided support integral body under the use of pull strength, to deform, because traction apparatus adopts alloy to make, make the whole distraction procedure can be according to the raising of temperature and autostable finishing.In addition, again because this utility model is simple in structure, easy to operate, when improving pull strength and security performance, also satisfy the patient upper jaw bone has independently been drawn requirement separately, not only shortened the patient treatment cycle, saved expense required when treating, also reach the obvious treatment effect, thereby alleviated patient's misery.
More than disclosed only be several specific embodiment of the present utility model, still, this utility model is not limited thereto, any those skilled in the art can think variation all should fall into protection domain of the present utility model.
