Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, be clearly and completely described the technical scheme in this utility model embodiment, obviously, described embodiment is only this utility model part embodiment, instead of whole embodiments.Based on the embodiment in this utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of this utility model protection.
Embodiment one
See Fig. 1, it is the structural representation of an embodiment of a kind of fracture reduction fixing clamp of the present utility model.In the present embodiment, this fracture reduction fixing clamp comprises the first hinged tong arm 11 and the second tong arm 12, wherein, the top of the first tong arm 11 is provided with the first arc binding clip 13, the top of the second tong arm 12 is provided with second, three arc binding clips 14, 15, particularly, in the present embodiment this second, three arc binding clips 14, 15 all in same plane, and this second arc binding clip 14 is between the first arc binding clip 13 and the 3rd arc binding clip 15, and the clearance distance between this second binding clip 14 and the 3rd binding clip 15 is 45mm-65mm, in addition, this the first arc binding clip 13 is provided with multiple guide channel 16, and the angle of each guide channel is different.Because needs arrange multiple guide channel on the first arc binding clip 13, therefore, in the present embodiment, the size of this first arc binding clip 13 should be greater than second and third arc binding clip 14,15.
See Fig. 2 and Fig. 3, in the present embodiment, being set side by side with on this first binding clip 13 runs through five elements' guide channel 16 of binding clip, and the number of the guide channel of often going is 5, and the acute angle scope between the central axis of two guide channels adjacent in often going is 5 °-25 °.That is to say in the present embodiment, because this guide channel is arranged on the first binding clip, because this first binding clip has certain radian, therefore, the direction that radian along this first binding clip arranges each guide channel is different, namely be not parallel to each other between each passage, the extended line of each guide channel may be intersect at a point, see Fig. 3.Certainly according to practical situation, the delay line of each guide channel of often going intersects at two different points or multiple point is also understandable, and the extended line of each guide channel intersects at a point or two points etc. are also understandable in adjacent rows, namely only needing it to meet when implanting Kirschner wire, Kirschner wire can be made to implant optimum position by this guide channel.
In order to can better fix, in the present embodiment, be also provided with anti-slip veins 17 separately, see Fig. 1 in the inner side of the first arc binding clip 13, second arc binding clip 14 and the 3rd arc binding clip 15.The inner side of this first, second and third arc binding clip in the present embodiment, refers to the one side of its arc-shaped recess, namely for being engaged the one side of clamping.When implementing particularly, in the present embodiment, this anti-slip veins 16 is zigzag screw thread, or not multiple projection.
Further, for the ease of regulating and fixing, the governor motion that can be used for the spacing of adjustment first tong arm 11 and the second tong arm 12 is also set between the first tong arm 11 and the second tong arm 12 in the present embodiment.See Fig. 1, in the present embodiment, this governor motion specifically comprises helical axis 21 and set bolt 22, wherein, one end of helical axis 21 is fixed on the postmedian of the first tong arm 11, and set bolt 22 is fixed on the postmedian of the second tong arm 12, and is set in the free end of helical axis 21.
In certain the present embodiment, this governor motion can also adopt ratchet and detent mechanism to realize, as ratchet being fixed on the postmedian of the first tong arm by rotating shaft, and ratchet is arranged on the top of this ratchet, namely its one end is fixed on the postmedian of the first tong arm, the other end, i.e. free end, be meshed with the sawtooth of above-mentioned ratchet, and a tooth bar is set at the postmedian of the second tong arm, when the first tong arm and the second tong arm are drawn close mutually, namely sawtooth on this tooth bar is meshed with the sawtooth of ratchet, thus realizes the adjustment of the spacing of two tong arms and fix.Certainly in order to simply, on the first tong arm and the second tong arm, be directly provided with the ladder button of sawtooth, realize fixingly also being appreciated that by the photograph occlusion between two ladder buttons.
Above disclosedly be only this utility model preferred embodiment, certainly the interest field of this utility model can not be limited with this, one of ordinary skill in the art will appreciate that all or part of flow process realizing above-described embodiment, and according to the equivalent variations that this utility model claim is done, still belong to the scope that utility model contains.
