Detailed description of the invention:
During details below describes, element numbers can be indicated in the diagram enclosed becomes some therein, and represents with the particular example describing mode of this embodiment practicable。Enough details can be described this kind of embodiment so that the general those skilled in the art in this field are had to implement。The person of readding it is understood that also can utilize in this utility model other embodiment or make under the premise not departing from described embodiment structural, logicality and electrically on change。Therefore, details hereafter describes and will be not intended to be considered to be a kind of restriction, otherwise, the embodiment wherein comprised will be defined by right。
With reference to Figure of description 1, a kind of pelvis external fixed mount, including a C type frame 100, a pair positioning needle 200 and a pair location hook 300, lower above-mentioned three big assemblies are described in detail。
With reference to description Fig. 1 ~ Fig. 5, a C type frame 100；This C type frame includes a connecting rod 101 and is positioned at C type frame both wings and linking arm 102 joining with connecting rod two ends；Described linking arm one end couples positioning needle and location hook, and the other end is set in connecting rod and moves along connecting rod；The two ends of described connecting rod are all uniformly laid with the first jack 103 offered from top to bottom, above-mentioned linking arm is provided with the second jack 104 matched with the first jack, and described first jack and the second jack are provided with the latch 105 being positioned in connecting rod by linking arm；Described latch is provided with a block 106, described block is positioned at the second jack and is undertaken on the top of connecting rod, this utility model is in use, according to the build that the wounded is different, can be deacclimatized by the distance between change two linking arms, particularly as follows: first latch is taken out, then linking arm is moved along connecting rod, until during suitable position, inserting the first jack by latch and two linking arms be fixed in connecting rod by the second jack。
In this utility model one preferred embodiment, the second jack is more than the first jack, and the shape of block and the second jack is similar, carries out rounding process in the second jack top edge or is arranged to inclined-plane simultaneously, conveniently taking out latch。
First jack is each provided with a row at the two ends of connecting rod, and the second jack on linking arm can be arranged to two, is positioned at the two ends of linking arm。
With reference to description Fig. 1, Fig. 5, Fig. 6 and Fig. 7, a pair positioning needle 200, this two positioning needle is separately positioned on the two ends of above-mentioned C type frame opening；Above-mentioned positioning needle one end is towards pelvis 10 and for supporting the alar part 11 of pelvis, and the other end and C type frame are connected；In this utility model, positioning needle can have two kinds of designs: a kind of is passivity 201, and another is the tip 202 that can penetrate skin, the setting of similar sub warhead；This positioning needle and C type frame are actively coupled, in particular: the described positioning needle other end is provided with screw thread, corresponding position, described C type frame opening two ends is provided with the screw matched with screw thread, so can according to the different condition of the injury of the wounded, select different positioning needles, the convenient replacing to positioning needle。
With reference to description Fig. 1, Fig. 2, a pair location hook of Fig. 5, Fig. 6 and Fig. 7 300, this two location hook is separately positioned on the two ends of above-mentioned C type frame opening and is positioned at positioning needle inboard；Hook 301 part of above-mentioned location hook one end is used for positioning crista iliaca 12, and the other end and C type frame are connected；Described location hook and C type frame are actively coupled, in particular: described on the C-shaped frame offers and slides through hole 107；The described location hook other end couples a screw rod 302, and this screw rod is positioned at and slides and sliding through hole；Described screw rod two ends are provided with the nut 303 being located on the C-shaped frame；In use: because of being ignorant of of different the wounded's pelvis size, so crista iliaca is positioned being, the distance of hook and positioning needle is to differ, so when not changing positioning needle, it is necessary to change location hook, it is designed into moveable, first loosening nut is only needed during use, screw rod is regulated to the position needed, locking nut, location hook is fixed on and slides on through hole。
