The specific embodiment
Below in conjunction with the drawings and specific embodiments, a kind of intramedullary pin navigation system that is flexible coupling of the present utility model is described further.Following each embodiment is only not limitation of the utility model for this utility model is described.
Fig. 1 is the structural representation of the intramedullary pin navigation system that is flexible coupling of the present utility model; Fig. 2 is the structural representation of soft main nail far-end of the present utility model; Fig. 3 is the structural representation of locating rod of the present utility model.As shown in Figure 1 to Figure 3, the intramedullary pin navigation system that is flexible coupling of the present utility model, comprises and is connected to far-end guide rod 6, near-end guide rod 7 and the handle 8 that locating rod 1, far-end locating rack 5 and far-end locating rack T connector one end of main 2 far-ends are connected successively.The threaded one end of handle 8 is connected with main nail 2 near-ends.
Main nail 2 far-ends cave inward and form locating platform 10, and the central authorities of locating platform 10 are provided with screwed hole 11, and the head of locating rod is connected in screwed hole 11.
The head of locating rod 1 is provided with head threads 12, coordinates with main oncomelania pit 11.The middle part of locating rod 1 is set to bar portion flexible axle 13, and the top of bar portion flexible axle is formed with locating groove 14.Afterbody forms handle connecting portion 15, and is connected with quick-mounting handle 9.Locating rod 1 outer cover is connected to sleeve pipe 4, and fixing with positioning wedged block 3, and far-end locating rack 5 is connected with positioning wedged block 3.
The assemble method of the intramedullary pin navigation system that is flexible coupling of the present utility model is: the threaded one end of handle 8 is fixing with being threaded in the U-shaped groove of intramedullary pin near-end, handle 8 other ends are connected with the narrower side of near-end guide rod 7, and T connector one side of near-end guide rod 7 and a thinner side of far-end guide rod 6 are fixedly connected with, thus the main anchor of the intramedullary pin operating theater instruments forming.The device of locating rod 1 in intra medullary nail far-end location is inserted to sleeve pipe 4 is interior to be fixed in the far-end positioning spiro pit 11 that simultaneously aims at femur, the main nail 2 of tibia with positioning wedged block 3.Finally with far-end locating rack 5, main anchor is connected with the fixed support in femur, tibial intramedullary nailing distal threads hole.The first end of type of far-end locating rack 5 is connected with far-end guide rod 6, and opposite side is stuck in the U-shaped groove of positioning wedged block 3 rear ends.Formed thus complete intramedullary pin operating theater instruments fixed support.
