Detailed description of the invention
As Fig. 1, Fig. 2, shown in Fig. 3, a kind of vertebra dynamic growth rod, comprise at least one pitman 1, elastic ferrule 2, sleeve pipe 3 and cover plate 4, the shape of elastic ferrule 2 is taper, the monolateral tapering of elastic ferrule 2 is 2 °-10 °, elastic ferrule 2 is in axial direction provided with a groove 5, elastic ferrule 2 is in axial direction also provided with at least one groove 6, the notch of groove 6 is arranged on the osculum of cone shaped elastic cutting ferrule 2, pitman 1 is arranged with elastic ferrule 2, pitman 1 is arranged in sleeve pipe 3 by elastic ferrule 2 interference fit, sleeve pipe 3 is threaded connection cover plate 4.
Wherein as shown in figures 1 and 3, pitman 1 quantity is 1, sleeve pipe 3 one end is bellmouth, sleeve pipe 3 other end is circular hole, pitman 1 is arranged with elastic ferrule 2, pitman 1 is arranged in sleeve pipe 3 by elastic ferrule 2 interference fit, and elastic ferrule 2 is arranged in the bellmouth of sleeve pipe 3, and cover plate 4 is threaded connection on the end face in the upper conical hole of sleeve pipe 3.
As shown in Figures 2 and 3, pitman 1 quantity is 2, sleeve pipe 3 two ends are bellmouth, centre is circular hole, every root pitman 1 is arranged with elastic ferrule 2 respectively, two pitmans 1 are symmetrically set and two symmetrical end faces are respectively equipped with limited block 7, two pitmans 1 respectively by respective elastic ferrule 2 interference fit to arrange in sleeve pipe 3 and elastic ferrule 2 is arranged in the bellmouth of sleeve pipe 3, the end face of sleeve pipe 3 two ends bellmouth is threaded connection cover plate 4.
This utility model pitman 1 is arranged in elastic ferrule 2, and pitman 1 is arranged in sleeve pipe 3 by elastic ferrule 2 interference fit, sleeve pipe 3 plays the effect of being connected and fixed, when pitman 1 is stressed press down time, elastic ferrule 2 can press down together along with pitman 1, due to tapering, the open slot on elastic ferrule 2 can shrink, and pitman 1 is lock onto in the internal taper hole of sleeve pipe 3 by elastic ferrule 2.And the cover plate 4 that is threaded on the end face in the upper conical hole of sleeve pipe 3, prevent elastic ferrule 2 from running out of the sliding scale of sleeve pipe 3 when being subject to withdrawal force.Wherein when pitman 1 quantity is 2, the setting that pitman 2 is symmetrical and respectively by the limited block 7 that is threaded on the plane of symmetry of 2 pitmans 1, make it ensure can not be drawn out of in elastic ferrule 2 when extracting.
This utility model, by simple tapered configuration, can make dynamic growth rod increase along with the growth of patient, the misery that the second operation avoiding patient to cause due to growth and Repeated Operation bring.And have the selection of unidirectional and two-way growth, effectively shorten operating time of doctor and the patient foreign body sensation in use procedure.
