Abstract
The utility model relates to a rotating-preventing saddle condylar steel plate which is composed of a condylar part, a bone front plate, a bone outside lateral plate, an arch bridge, a bone penetrating window and a fixing hole. The condylar part is suitable for not only a spongy bone screw but also a bone bolt for treating an intercondylar fracture in a fixing mode. The bone front plate and the bone outside lateral plate form a saddle seat which is spanned on a bone. After screws are crossed to be fixed, the screws can prevent rotation, and the screws are steady and reliable. The utility model is suitable for not only an intersect type fracture on a condylus but also a comminuted fracture on the condylus and between the condyluses.
Description
This utility model belongs to medical field, more precisely is a big technological improvement that belongs to the medical operating inner fixer, and its name is called the anti-saddle-shaped condylar plate that revolves.
In the prior art, at present the AO condyle plate of usefulness is strong clinically, but be difficult to moulding, the fixing inside and outside talipes varus of improper easy generation.Flute profile L end is big to bone structure destruction when squeezing into, and is difficult to extract, the operation technique difficulty, and Zickel intramedullary needle and Ender nail fixedly are difficult to reach anatomical reduction, only are suitable for II type fracture.Though the moulding convenience of L-trapezoid compression plate, the bone groove of digging out with goose saw or osteotome in advance of squeezing into of L end is difficult to accurately grasp the kneed valgus angle of maintenance.Operation certainly will be wasted time and energy the steel plate bending of having a competition repeatedly in the art, and very inconvenience especially to comminuted fracture, is difficult to reach reduction with good and fixing sometimes.The comminuted fracture of supracondylar fracture type is particularly arranged again for fracture between the existing condyle of distal part of femur, more make the patient thorny, its key issue is still to lack the comparatively ideal internal fixation apparatus of treatment this type fracture at present.
The purpose of this utility model is that we have designed a kind of name according to the skeleton specimen and have been called the anti-saddle-shaped condylar plate that revolves in order to address the above problem.Can be used in all types of fracture of distal part of femur, not only the anti-intensity of revolving of bending resistance is big for the saddle structure, more importantly is that condyle portion has valgus angle, has good anatomical reduction and touches the plate effect, and it is easy for installation, and is fixing simple and easy to do.
The purpose of this utility model is achieved in that prevents that revolving saddle-shaped condylar plate is made up of condyle portion, bone header board, bone outer panel, arch bridge, fixing hole, deep window, is a bodily form.The condyle portion likeness in form ectocondyle of condyle plate has 5 °-8 ° valgus angle, is used to guarantee that angle resets well.The nail hole is used for cancellous bone screw and the bone bolt is fixed on the condyle portion fixing head.Condyle portion is connected with outer panel is curved, and outer panel is used for fixing on the condyle and key portion.Between bone header board and bone outer panel deep window is arranged, bend inwards thus, form arch bridge and connect, the likeness in form saddle.Before in the time of fixedly, outside plate straddles on the skeleton.Fixing holes preceding, outer both sides are staggered, and the screw after fixing is X-type in bone, play stable reaching and prevent the effect of revolving.Deep window between arch bridge can be looked at reset case straight, can make the bone piece of rear side in being screwed again.
In order to be illustrated more clearly in this utility model, utility model is described further below in conjunction with accompanying drawing.
Accompanying drawing is an appearance structure sketch map of the present utility model.
1, a kind of by condyle portion (9), bone header board (4), bone outer panel (8), arch bridge (2), (7), fixing
The anti-saddle-shaped condylar plate that revolves that hole (1), (5), (10) and deep window (3), (6) are formed.
2, describedly anti-revolve saddle-shaped condylar plate according to above-mentioned 1, it is characterized in that condyle portion (9) likeness in form femur
Ectocondyle, its head end have a circle to lack.Condyle portion (9) locates to be at arch bridge (2) with bone outer panel (8)
The arc abduction, and form 5 °-8 ° valgus angle.Reset with the angle that adapts to femoral lateral condyle.
3, describedly anti-revolve saddle-shaped condylar plate according to above-mentioned 1, it is characterized in that outside bone header board (4) and the bone
Plate (8) connects and composes saddle by arch bridge (2), (7), straddles on the skeleton, is used for preceding, outer
Side is fixed, and plays stable, bending resistance and anti-ly revolves effect.Between bone header board and bone outer panel (4), (8)
Deep window (3), (6), can look at reduction of the fracture situation straight, also can be used for screw and fix.
4, describedly anti-revolve saddle-shaped condylar plate according to above-mentioned 1, it is characterized in that used material is nontoxic
Rust steel material.
Claims (2)
1, the anti-saddle-shaped condylar plate that revolves of a kind of bodily form by condyle portion (9), bone header board (4), bone outer panel (8), arch bridge (2), (7), deep window (3), (6), fixing hole (1), (5), (10), formation, the ectocondyle that it is characterized in that condyle portion (9) likeness in form femur, its head end have a circle to lack.Condyle portion (9) locates to be the circular arc abduction with bone outer panel (8) at arch bridge (2), and forms 5 °-8 ° valgus angle, and bone header board (4) is connected to the saddle structure with bone outer panel (8) by arch bridge (2), (9).Between two plates (4), (6) deep window (3), (6).
2, prevent revolving saddle-shaped condylar plate according to claim 1 is described, it is characterized in that used material is nontoxic stainless steel material.
