Detailed description of the invention
In order to understand the present invention further, below in conjunction with embodiment, the preferred embodiment of the invention is described, but should be appreciated that these describe just for further illustrating the features and advantages of the present invention, instead of limiting to the claimed invention.
Shown in ginseng Fig. 1 to Fig. 3, a kind of distal radius supports 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 arranged in curved surface, described curved surface is waveform, the benefit of this design is: the tendon of fracture can be connected on the bone in waveform depression, thus 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, arrange two benefits that ranked first screwed hole 21 to be: can select wherein one to ranked first screwed hole and be fixed according to the position of concrete fracture line during operation, 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 is arranged.By observation port 10, doctor can observe the situation of fracture line at any time in operation process, described afterbody 3 is provided with several second screwed hole 30, the side of described afterbody 3 be provided with several first protuberance 31 and with spaced several first recess 32 of the first protuberance 31, the opposite side of described afterbody 3 be provided with several second protuberance 33 and with spaced several second recess 34 of the second protuberance 33, described several first protuberance 31 is symmetrical arranged with several second protuberance 33, described several first recess 32 is symmetrical arranged with several second recess 34, and described afterbody 3 meets:
Relational expression 1:f=a+b;
Relational expression 2:a=b;
Wherein, the beeline between the f: the first recess 32 and the second recess 34, the first recess 32 and the second recess 34 symmetrical; A: the first protuberance 31 is from the ultimate range of nearest second screwed hole 30; B: the second protuberance 33 is from the ultimate range of nearest second screwed hole 30.The design of this size relationship formula is mainly in order to avoid stress is concentrated, if f to be designed to f < a+b, that is when doctor carries out bending reconstruction to steel plate, be easy between first recess 32 and the second recess 34 because stress concentrates and rupture, equally, as a>b, during reconstruction, the second protuberance 33 easily ruptures, otherwise as a<b, during reconstruction, the first protuberance 31 easily ruptures.The both sides of described afterbody 3 are that undaform is arranged, described body 1 is also provided with the 3rd screwed hole 12 between observation port 10 and pressurization hole 11, described first screwed hole 21, second screwed hole 30 and the 3rd screwed hole 12 are taper thread hole, can prevent lock screw from moving back nail.2 liang, described head ranked first in screwed hole 21, and the quantity that ranked first screwed hole near 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 second screwed hole 30 is five.Described distal radius support the width of locking steel plate along head 2 rearwardly 3 direction narrow gradually.Described distal radius supports that 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 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, the corrugated structural design in steel plate tail 3 both sides of the present invention is compared to both sides of the prior art linear design, its bending angle is more prone to control, doctor operates convenient, substantially increases the reconstruction performance of steel plate.Described distal radius supports that locking steel plate is also provided with several Kirschner wire fixation hole 4, and described several Kirschner wire fixation hole 4 is for carrying out pre-determined bit to locking steel plate, and described distal radius supports that locking steel plate is made up of pure titanium material.
Beneficial effect of the present invention is: the present invention arranges protuberance and recess respectively by the both sides of afterbody 3, thus the bending being beneficial to steel plate is rebuild, certain relational expression is met by the size design of protuberance and recess, thus avoid stress to concentrate, the present invention is by arranging observation port 10 at body 1, thus can facilitate doctor in operation process, observe the situation of fracture line at any time, the end face of head 2 is designed to waveform by the present invention, the tendon of fracture can be connected on the bone in waveform depression, thus 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 select wherein one to ranked first screwed hole and be fixed according to the position of fracture line respectively, therefore the suitability be wider.
More than show and describe 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 by the restriction of above-mentioned example; what describe in above-mentioned example and description 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 application claims protection domain is defined by appending claims and equivalent thereof.
