Description
Technical field
This utility model relates to a kind of tibia and fixes hone lamella, and after referring to a kind of proximal tibia especially, hone lamella fixed by inner side platform.
Background technology
The skeletal shape of partes corporis humani position is not quite similar and complex structure; if there is the injuries such as fracture; treatment is medically provided usually to need the skeletal structure according to injury with the mode of rehabilitation and give suitable treatment; when the position of fracturing is near joint; comparatively be not suitable for using plaster fixing, then usually can take the fixture that hone lamella and nail are fractured as treatment.
For the fracture of proximal tibia (can be described as fracture of the tibial plateau again), when patient is subject to high-octane wound, as traffic accident, strong collision or by high falling; Or low-energy wound, as slipped or falling down, the inner side of tibial plateau or outside all may be caused to be subject to setback and to fracture, and on rear side of tibia, platform is impacted and the situation of subsiding is also not rare, therefore needs to be fixed by tibial plateau with hone lamella.
But, because the anatomic construction on rear side of tibial plateau is complicated and neural blood vessel and important tendon are covered with in this, so the fixed form on rear side of traditional tibial plateau is first indirect first by after bone reduction via outside before tibial plateau, first rear side is entered to by outside before tibial plateau again for the anterolateral hone lamella of tibial plateau, finally indirectly fix again, but this kind of mode often faces and cannot really will reset on rear side of tibial plateau or fix, and operating time is consuming time longer, add specific also very rare for the hone lamella on rear side of tibial plateau, therefore the hone lamella being used in other position only can be utilized to be fixed by the tibial plateau of fracture, but the goodness of fit of its hone lamella plate shape and surface of bone may be poor, and implant after stability and comfort level also bad, in addition, the hone lamella that general tradition uses is be attached on skeleton completely, and the frictional force relied between hone lamella and skeleton is to reach fixing effect, but because this fixed form can cause the blood transportation of fracture site bad to periosteum pressurization, also can cause the indolence of postoperative fracture or the generation of other complication simultaneously.In addition, if patient suffers from osteoporosis, the operation fixed form that also recommendation is not above-mentioned.Therefore above-mentioned post-operative recovery effect also can present not good situation, therefore needs to develop the hone lamella being applicable to platform position, inner side after proximal tibia, and after making impaired proximal tibia, inner side platform has good recovery after surgery.
Utility model content
In view of the above problems, the purpose of this utility model be to provide a kind of not need to fit on skeleton and after the proximal tibia subsiding or fracture for inner side platform after proximal tibia inside platform fix hone lamella, make fixing needs of hone lamella rely on the frictional force between hone lamella and skeleton, and the interlocking structure of hone lamella self can be relied on completely to reach fixed effect.When hone lamella of the present utility model not with bone-contact, and make to have between hone lamella and skeleton space, except hone lamella can be eliminated, possible syndrome (as slow in courses of infection, union of fracture, fix unsuccessfully etc.) is caused to the pressurization of skeleton institute, also can improve the blood transportation of affected part and the recovery of periosteum and growth.In one embodiment, hone lamella of the present utility model can be applicable to again to suffer from it osteoporotic patient.
After another object of the present utility model is to provide a kind of proximal tibia, hone lamella fixed by inner side platform, and above-mentioned hone lamella can not in prior pre-bending, make size and the damage situations of inner side after the visual sufferer proximal tibia of medical personnel, and determine bending hone lamella head angle and after implanting proximal tibia inner side platform to reach fixing effect.
In the first embodiment of the present utility model, after proximal tibia of the present utility model, inner side platform is fixed hone lamella and is comprised a head, the whole body portion, the first side and the second side, and wherein head is a plane plate; Body portion is a wave plate body, and head and body portion are sequentially one-body molded; And the second side of above-mentioned hone lamella can be passed through bending and has curvature, its curvature is conformed to the curvature of sufferer tibia; And this hone lamella is provided with further multiple perforation and a locating hole through the first side of hone lamella and the second side.
Preferably, a suitable curvature can be bent to hone lamella head, make the second side curvature of the head of hone lamella can correspond to the articular surface curvature of proximal tibia; Moreover, also can do a bending to hone lamella body portion, make the second side curvature in the body portion of hone lamella can correspond to the milder surface configuration of the key near-end of tibia.
In the second embodiment of utility model, this utility model provide a kind of there is the proximal tibia of anti oxidation layer after inner side platform fix hone lamella, not only above-mentioned hone lamella surface but also there is an anti oxidation layer further, its production method is the surface layer first utilizing the mode of sandblasting pickling to remove hone lamella, then carry out with laser the hole that the above-mentioned hone lamella of sectional repair produces after sandblasting pickling, then the surface of above-mentioned hone lamella is ground to reduce the roughness of above-mentioned plate surface, again polishing is carried out on its surface, finally by modifying surface, , the surface that after making proximal tibia, hone lamella fixed by inner side platform has a wear-resisting anti oxidation layer.In one embodiment, above-mentioned hone lamella material can be again the material of titanium or titanium 6 aluminum 4 vanadium (Ti6Al4V).In another embodiment, above-mentioned hone lamella material can be steel again.
Preferably, above-mentioned perforation is screw form.
Preferably, above-mentioned locating hole ovalize.
Preferably, after above-mentioned proximal tibia, inner side platform is fixed hone lamella and is provided with multiple open-work further through the first side of this hone lamella and the second side, and multiple open-work can be run through for steel wire.
In certain embodiments, the head of above-mentioned fixing hone lamella and the shape in body portion are symmetrical.And in another embodiment, in use, the body portion of hone lamella is carried out cutting to meet demand to described hone lamella by visual patient's tibia length.
In certain embodiments, after after closing nail or location nail fixed tibial near-end by locating hole bolt, hone lamella fixed by inner side platform, again using nail or location nail as slide bar, locating hole is as chute, after making proximal tibia, the displacement that hone lamella can carry out to a certain degree on tibia fixed by inner side platform, and fix inner side platform after the header circumscribes proximal tibia of hone lamella via inner side platform after proximal tibia, bolt closes other nail inner side platform and perforation of tibia backbone after proximal tibia and to go forward side by side horizontal reset adjustment again, after making proximal tibia, inner side platform is fixed hone lamella and not easily produce angular deviation when fixing.
