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 to Fig. 3, a kind of distal radius is supported locking steel plate, comprise: body 1, be arranged at the head 2 of body 1 one end and be arranged at the afterbody 3 of body 1 other end, the end face 20 of described head 2 is curved surface setting, described curved surface is waveform, the benefit of this design is: the tendon of fracture can be connected on the bone in waveform depression, thereby is conducive to the recovery of tendon.Described head 2 is provided with the first screwed hole 21 that two rows be arranged in parallel, two benefits that ranked first screwed hole 21 are set to be: during operation, can select wherein one to ranked first screwed hole and be fixed according to the position of concrete fracture line, therefore the suitability is wider, described body 1 is provided with observation port 10 and pressurization hole 11, in the present embodiment, described pressurization hole 11 ovalize settings.By observation port 10, doctor can observe at any time the situation of fracture line in operation process, described afterbody 3 is provided with several the second screwed holes 30, one side of described afterbody 3 be provided with several the first protuberances 31 and with spaced several the first recesses 32 of the first protuberance 31, the opposite side of described afterbody 3 be provided with several the second protuberances 33 and with spaced several the second recesses 34 of the second protuberance 33, described several the first protuberance 31 is symmetrical arranged with several the second protuberances 33, described several the first recess 32 is symmetrical arranged with several the second recesses 34, and described afterbody 3 meets:
Relational expression 1:f=a+b;
Relational expression 2:a=b;
Wherein, f: the beeline between the first recess 32 and the second recess 34, the first recess 32 and the second recess 34 are symmetrical; A: the first protuberance 31 is from the ultimate range of nearest the second screwed hole 30; B: the second protuberance 33 is from the ultimate range of nearest the second screwed hole 30.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 32 and the second recess 34, be easy to rupture because of stress concentration, same, when a>b, during reconstruction, the second protuberance 33 easily ruptures, otherwise when a<b, during reconstruction, the first protuberance 31 easily ruptures.The both sides of described afterbody 3 are undaform setting, described body 1 is also provided with the 3rd screwed hole 12 between observation port 10 and pressurization hole 11, described the first screwed hole 21, the second screwed hole 30 and the 3rd screwed hole 12 are taper thread hole, can prevent that lock screw from moving back nail.2 liang, described head ranked first in screwed hole 21, near a quantity that ranked first screwed hole of observation port 10, is four, and the quantity that ranked first screwed hole away from one of observation port is five, and the quantity of described the second screwed hole 30 is five.The direction of the width of described distal radius support locking steel plate along head 2 to afterbody 3 narrows down gradually.Described distal radius supports locking steel plate 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 steel plate afterbody 3 corrugated structural designs in both sides of the present invention design 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 distal radius supports that locking steel plate is also provided with several Kirschner wire fixing holes 4, and described several Kirschner wire fixing holes 4 are for locking steel plate is carried out to pre-determined bit, and described distal radius supports locking steel plate to be made by pure titanium material.
Beneficial effect of the present invention is: the present invention arranges respectively protuberance and recess by the both sides of afterbody 3, thereby the bending that is beneficial to steel plate is rebuild, size design by protuberance and recess meets certain relational expression, thereby avoid stress concentration, the present invention is by arranging observation port 10 at body 1, thereby can facilitate doctor in operation process, to observe at any time the situation of fracture line, the present invention is designed to waveform by the end face of head 2, the tendon of fracture can be connected on the bone in waveform depression, thereby is conducive to the rehabilitation of tendon.The present invention arranges two benefits that ranked first screwed hole 21 at head 2 and is: can be respectively according to the position of fracture line, select wherein one to ranked first screwed hole and be fixed, so the suitability is wider.
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.
