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.
Ginseng Fig. 1 to Fig. 3, a kind of capitulum radii locking steel plate, comprise: the steel plate body 1 of elongated setting and the head 2 extending from one end of steel plate body 1 bending, described steel plate body 1 is provided with several first screwed holes 10 of linearly arranging, described head 2 is provided with several second screwed holes 20 of setting triangular in shape, one side of described steel plate body 1 be provided with several the first protuberances 11 and with spaced several the first recesses 12 of the first protuberance 11, the opposite side of described steel plate body 1 be provided with several the second protuberances 13 and with spaced several the second recesses 14 of the second protuberance 13, described several the first protuberance 11 is symmetrical arranged with the longitudinal axis of several the second protuberances 13 with respect to steel plate body 1, described several the first recess 12 is symmetrical arranged with the longitudinal axis of several the second recesses 14 for steel plate body 1, described steel plate body 1 meets:
Relational expression 1:f=a+b;
Relational expression 2:a=b;
Wherein, f: the beeline between the first recess 12 and the second recess 14, the first recess 12 and the second recess 14 are symmetrical; A: the first protuberance 11 is from the ultimate range of nearest the first screwed hole 10; B: the second protuberance 13 is from the ultimate range of nearest the first screwed hole 10.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 12 and the second recess 14, be easy to rupture because of stress concentration, same, when a>b, during reconstruction, the second protuberance 13 easily ruptures, otherwise when a<b, during reconstruction, the first protuberance 11 easily ruptures.Between described head 2 and steel plate body 1, arrange in obtuse angle, the both sides of described steel plate body 1 are undaform setting.The quantity of described the first screwed hole 10 is five, and the quantity of described the second screwed hole 20 is six, and described the first screwed hole 10 and the second screwed hole 20 are taper thread hole, and the direction of the width of described capitulum radii locking steel plate along head to steel plate body narrows down gradually.Described capitulum radii 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, greatly improved the reconstruction performance of steel plate.Described capitulum radii locking steel plate is made by pure titanium material, therefore has higher intensity.
The present invention arranges respectively protuberance and recess by the both sides of steel plate body, thus the bending that is beneficial to steel plate rebuild, the size design by protuberance and recess meets certain relational expression, thereby avoids stress concentration.By described head, be provided with several second screwed holes 20 of setting triangular in shape, thereby can make between locking steel plate and radius fixing more firm.
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.
