Detailed description of the invention
In order to there be understanding clearly to technical characteristic of the present utility model, object and effect, now contrast accompanying drawing and detailed description of the invention of the present utility model is described.Wherein, identical parts adopt identical label.
Fig. 1 is the structural representation of a kind of threading apparatus for bone surgery according to a specific embodiment of the present utility model; Shown in Figure 1, the utility model proposes a kind of threading apparatus for bone surgery, it comprises, at least two curved pipes 1 that can mutually splice, described curved pipe 1 is provided with the first connecting portion 11 and/or the second connecting portion 12, is rotatably connected between described curved pipe 1 by mutual nestable described first connecting portion 11 and described second connecting portion 12.
Fig. 3 is the use procedure principle schematic of the threading apparatus for bone surgery of Fig. 1, see Fig. 1, shown in 3, threading apparatus for bone surgery provided by the utility model, it is spliced by multiple described curved pipe 1, the arc chord angle α of each described curved pipe 1 correspondence can be 60-90 degree, be rotatably connected between adjacent described curved pipe 1, like this, when surgical wound surface is less, namely surgical field of view and working place smaller time, can first adjacent described curved pipe 1 be rotated to certain angle, the skeleton 2 of can fitting of curved pipe 1 described in first segment is detoured downwards, after curved pipe described in first segment 1 detours and puts in place, curved pipe 1 described in rotatable second section makes itself and described skeleton 2 fit, thus by promoting curved pipe 1 described in second section, curved pipe 1 described in curved pipe 1 described in first segment and second section all can be fitted described skeleton 2 is around the downside to described skeleton 2, so just can guarantee there is no the tissue such as blood capillary or muscle between described curved pipe 1 and described skeleton 2.Then threading operation can be carried out in described curved pipe 1.Certainly, also first cable can be penetrated described curved pipe 1, then carry out the operation walking around described skeleton 2.
In order to simplify accompanying drawing, shown in Fig. 1,3, only used two described curved pipes 1 in the present embodiment, threading apparatus for bone surgery provided by the utility model, it can be spliced by multiple described curved pipe 1, when only having two described curved pipes 1 to be spliced, after completing threading operation, because cable also can play the effect of guiding, therefore, the another side that the instruments such as Medical forceps also can be utilized described curved pipe 1 to be shifted onto described skeleton 2 takes out.
Described curved pipe 1 is at least provided with described first connecting portion 11 or described second connecting portion 12, as long as a described curved pipe 1 is provided with described first connecting portion 11 like this, curved pipe 1 described in another is provided with described second connecting portion 12, just can be spliced into the described threading apparatus for bone surgery by these two described curved pipes 1.When the described threading apparatus for bone surgery is spliced by multiple described curved pipe 1, be then positioned at centre, the described curved pipe 1 that head and the tail are all connected with curved pipe described in other 1 just needs to be provided with described first connecting portion 11 and described second connecting portion 12 simultaneously.
Can be convenient to rotate between adjacent described curved pipe 1 to ensure, described first connecting portion 11 and described second connecting portion 12 are straight tube.
Described first connecting portion 11 and described second connecting portion 12 can be respectively arranged with corresponding female thread and external screw thread, connect by screw thread is mutually nested.
Described first connecting portion 11 and described second connecting portion 12 can also be measure-alike, all arrange external screw thread, are connected by a swivel nut.
Fig. 2 is the partial schematic sectional view of the splicing of the threading apparatus for the bone surgery state shown in Fig. 1; Shown in Fig. 1,2, in a preferred embodiment, described first connecting portion 11 is provided with sliding tray 111 in radial direction, and described second connecting portion 12 is provided with locating dowel 121.Described sliding tray 111 can be the groove across the cross section of the first connecting portion 11 described in half, the sidewall of described second connecting portion 12 can first arrange a through hole corresponding with described sliding tray 111 position, insert after described second connecting portion 12 until described first connecting portion 11, a metal bar is welded from described through hole, namely can be made into described locating dowel 121, described locating dowel 121 is stuck in described sliding tray 111, so just can limit the anglec of rotation between described first connecting portion 11 and described second connecting portion 12, in addition, described locating dowel 121 can also limit the axial displacement between described first connecting portion 11 and described second connecting portion 12.
Fig. 4 is that the A of Fig. 1 is to structural representation.Shown in Fig. 1,4, for the ease of the threading apparatus for bone surgery provided by the utility model being taken off from cable after threading, in a preferred embodiment, be provided with opening 13 inside described curved pipe 1, the size of described opening 13 can slightly larger than the diameter of cable.Described opening 13 makes described curved pipe 1 in the process walking around described skeleton 2, and groove is left in described skeleton 2 side of fitting.Like this, can ensure on the one hand cable in through the process of described curved pipe 1 can not with the tissue cross such as the blood capillary of described curved pipe 1 outside or muscle, on the other hand, after cable has been worn, can very easily described curved pipe 1 have been taken off from cable.
A kind of threading apparatus for bone surgery provided by the utility model, its skeleton of can fitting under the smaller visual field and working place condition is around arriving the side of skeleton away from surgical wound surface, thus cable can be helped to get around the tissue such as blood capillary or muscle as much as possible, laminating skeleton is tied up.
Although it will be appreciated by those skilled in the art that this utility model is described according to the mode of multiple embodiment, not each embodiment only comprises an independently technical scheme.So describe in description be only used to clear for the purpose of; description should integrally be understood by those skilled in the art, and regards technical scheme involved in each embodiment as the mode that mutually can be combined into different embodiment to understand protection domain of the present utility model.
The foregoing is only the schematic detailed description of the invention of this utility model, and be not used to limit scope of the present utility model.Any those skilled in the art, the equivalent variations done under the prerequisite not departing from design of the present utility model and principle, amendment and combination, all should belong to the scope of this utility model protection.
