The specific embodiment
In order further to understand the present invention, below in conjunction with embodiment, the preferred embodiment of the invention is described, but should be appreciated that these are described is for further illustrating the features and advantages of the present invention, rather than limiting to the claimed invention.
Shown in ginseng Fig. 1, a kind of tibial plateau rear pillar locking steel plate, comprise: the steel plate body 1 of strip and the rounded nose 2 extending from one end of steel plate body 1, the rounded setting of free terminal 10 of described steel plate body 1, described steel plate body 1 is provided with several the first screwed holes 11 of evenly arranging, in the present embodiment, the quantity of described the first screwed hole 11 is seven, described rounded nose 2 is provided with the second screwed hole 20 of several annular arrangements, in the present embodiment, the quantity of described the second screwed hole 20 is five, the second screwed hole of the prior art linearly arranges, when being subject to revolving force, do the used time, because be installed on the lock screw discontinuity in the second screwed hole, it is very poor that the stability of steel plate can become, serious steel plate likely can come off, in the present invention, the second screwed hole 20 arranges and has just in time solved this technical problem ringwise, when being subject to revolving force, do the used time, the lock screw being installed in the second screwed hole 20 is stressed all more even, therefore the stability of steel plate is better, thereby greatly improved the anti-rotation performance of steel plate, described steel plate body 1 is provided with observation port 3 with the junction of head 2, thereby facilitate doctor in operation process, to observe place, crack situation.One side of described steel plate body 1 be provided with several the first protuberances 12 and with spaced several the first recesses 13 of the first protuberance 12, the opposite side of described steel plate body 1 be provided with several the second protuberances 14 and with spaced several the second recesses 15 of the second protuberance 14, described several the first protuberance 12 is symmetrical with respect to the longitudinal axis of steel plate body 1 with several the second protuberances 14, described several the first recess 13 is symmetrical with respect to the longitudinal axis of steel plate body 1 with several the second recesses 15, and described steel plate body meets:
Relational expression 1:f=a+b;
Relational expression 2:a=b;
Wherein, f: the beeline between the first recess 13 and the second recess 15, the first recess 13 and the second recess 15 are symmetrical; A: the first protuberance 12 is from the ultimate range of nearest the first screwed hole 11; B: the second protuberance 14 is from the ultimate range of nearest the first screwed hole 11.In the present embodiment: described f=6.5mm, a=3.25 mm, b=3.25 mm.The design of this size relationship formula is mainly for fear of stress concentration, if f is designed to f < a+b, that is when doctor carries out bending reconstruction to steel plate, between the first recess 13 and the second recess 15, be easy to rupture because of stress concentration, same, when a>b, during reconstruction, the second protuberance 14 easily ruptures, otherwise when a<b, during reconstruction, the first protuberance 12 easily ruptures.
The equal undulate setting of dual-side of described steel plate body 1, described tibial plateau rear pillar locking steel plate is for rebuilding shape steel plate.In operation process, due to everyone Skeletal size, all there is some difference, therefore the steel plate of a fixed structure can not be applicable to everyone, therefore need steel plate to there is reconstruction capability, that is to say, when steel plate is installed on after human body, also need, according to everyone concrete skeletal shape, steel plate is carried out to bending fine setting, the corrugated structural design in steel plate body of the present invention both sides designs than both sides of the prior art straight line, its bending angle is more prone to control, doctor operates convenient, has greatly improved the reconstruction performance of steel plate.
Described tibial plateau rear pillar locking steel plate is made by pure titanium material, described several the first screwed hole 11 is located along the same line, described tibial plateau rear pillar locking steel plate is also provided with several Kirschner wire fixing holes 4, described several Kirschner wire fixing hole 4 is for carrying out pre-determined bit to locking steel plate, described the first screwed hole 11 and the second screwed hole 20 are taper thread hole, during installation, then several lock screw are screwed in tibia through the first screwed hole 11 and the second screwed hole 20 respectively, the benefit of described the first screwed hole 11 and the second screwed hole 20 tapered settings is: can prevent that lock screw from moving back nail.
The present invention arranges respectively protuberance and recess by the both sides of steel plate body, thereby be beneficial to the reconstruction of steel plate, size design by protuberance and recess meets certain relational expression, can avoid stress concentration, by several second screwed holes 20 of rounded nose are arranged to annular, thereby improved anti-rotational stability, by the junction at described steel plate body and head, be provided with observation port in addition, thereby facilitated doctor in operation process, to observe place, crack situation.
More than show and described ultimate principle of the present invention, principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not subject to the restriction of above-mentioned example; that in above-mentioned example and description, describes just illustrates principle of the present invention; the present invention also has various changes and modifications without departing from the spirit and scope of the present invention; these changes and improvements all fall in the claimed scope of the invention, and the claimed scope of the present invention is defined by appending claims and equivalent thereof.
