Detailed description of the invention
below in conjunction with accompanying drawing, the technical solution of the utility model is further elaborated.
shown in ginseng Fig. 1 and Fig. 2, the multi-direction locking steel plate of a kind of distal fibular, is made up of titanium alloy material, comprises: strip body 1 and head 2, described strip body 1 comprises first body 3 and the second body 4, and the free terminal of described first body 3 is that wedge is arranged.Described second body 4 is between first body 3 and head 2, described first body 3 is provided with the first kirschner nail fixing hole 5 and 5 the first screwed holes 6, described second body 4 is provided with second screwed hole 7 and 2 oval pressurization holes 8, and described first screwed hole 6, first kirschner nail fixing hole 5, pressurization hole 8 and the second screwed hole 7 are all located on the same line.Described head 2 is provided with the second kirschner nail fixing hole 9 and 3 the 3rd screwed holes 10, the setting triangular in shape of described three the 3rd screwed holes 10.The hole wall of described first screwed hole 6, second screwed hole 7 and the 3rd screwed hole 10 all offers 3 ~ 6 otch, described otch threadingly hole axis extend.Hole wall is divided into several sections by otch, during operation, what doctor can select hold-down screw according to the particular location of fracture line is screwed into angle, thread pore structure in this utility model can meet the multi-direction of hold-down screw and be screwed into demand, when hold-down screw is screwed in screwed hole, no matter twist to which direction, always have the female thread of a sector hole wall to screw mutually with the external screw thread of hold-down screw, all the other a few sector hole walls extrude hold-down screw, thus realize multi-direction locking.The quantity of described otch can not be too many, can not very little, and otch quantity is too many, and every sector hole wall is just narrow, will be inadequate with the power that screws of hold-down screw, if otch quantity is very few, cannot make again the multi-direction installation of hold-down screw.In the present embodiment, the hole wall of described first screwed hole 6, second screwed hole 7 and the 3rd screwed hole 10 all offers 4 otch 11,4 otch 11 circumferentially arranging in even at hole wall, the shape of described otch 11 is arc-shaped, add and adopt man-hour drill bit to get out, certainly in other embodiments, the shape of otch also can be rectangle, and rectangular slits adds man-hour requirement milling cutter and mills out.Screw thread in described first screwed hole 6, second screwed hole 7 and the 3rd screwed hole 10 is trapezoidal thread, thus greatly can improve coupling mechanism force.
the side of described first body 3 be provided with several first protuberance 12 and with spaced several first recess 13 of the first protuberance 12, the opposite side of described first body 3 be provided with several second protuberance 14 and with spaced several second recess 15 of the second protuberance 14, described several first protuberance 12 is symmetrical relative to the longitudinal axis of first body 3 with several second protuberance 14, described several first recess 13 is symmetrical relative to the longitudinal axis of first body 3 with several second recess 15, and described first body meets:
relational expression 1:f=a+b;
relational expression 2:a=b;
wherein, the distance between the f: the first recess 13 and the second recess 15, the first recess 13 and the second recess 15 symmetrical; A: the first protuberance 12 is from the distance of nearest screwed hole; B: with the distance of symmetrical the second protuberance 14 of the first protuberance 12 from nearest screwed hole.In operation process, due to everyone Skeletal size, all there is some difference, therefore the steel plate of one piece of fixed structure can not be applicable to everyone, therefore steel plate is needed to have reconstruction capability, that is, after steel plate is installed on human body, also need to carry out bending fine setting according to everyone concrete skeletal shape to steel plate, in this utility model, the design of first body 3 both sides protuberance and recess is compared to both sides of the prior art linear design, its bending angle is more prone to control, doctor operates convenient, substantially increase the reconstruction performance of steel plate, size design additionally by protuberance and recess meets certain relational expression, stress can be avoided to concentrate.
in sum, fibula distal end locking steel plate in this utility model by arranging the axially extended otch in several threadingly holes in screwed hole, thus the hole wall of screwed hole is divided into several sections, during operation, what doctor can select hold-down screw according to the particular location of fracture line is screwed into angle, thread pore structure in this utility model can meet the multi-direction of hold-down screw and be screwed into demand, when hold-down screw is screwed in screwed hole, which no matter twist to direction, the female thread of a sector hole wall is always had to screw mutually with the external screw thread of hold-down screw, all the other a few sector hole walls extrude hold-down screw, thus realize multi-direction locking.
above-described embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to this utility model spirit change or modify, and all should be encompassed in protection domain of the present utility model.
