Description
Technical field
This utility model relates to a kind of bracing or strutting arrangement being used for the treatment of femur head necrosis of hospital orthopedics.
Background technology
In existing clinical case, common relates to femur head necrosis mainly ischemic necrosis of femoral head (avascular necrosis of the femoral head, ANFH) destroy capital blood due to Different types of etiopathogenises to supply, make a pathological process in femoral head caused by osteonecrosis, in femoral head after osteonecrosis, body carries out nature reparation to necrotic area, necrotic bone girder is progressively absorbed, femoral head mechanical strength declines, cause collapse-deformation, cause the major injury of hip joint, support performance declines, under loading conditions, subchondral bone can be caused to bear ABNORMAL STRESS, cause articular step-off, there is Hip osteoarthritis, have a strong impact on hip joint function, affect patients ' life quality.
Three models is had at present: early treatment to the treatment of femur head necrosis, namely the treatment taked for the cause of disease, namely by bring vexation on oneself because of, remove the cause of disease, this method is the most thorough, ideal, but in the cause of disease of femur head necrosis, clear and definite or much indefinite, among current many causes of disease are still in and probe into, etiotropic treatment is not more known where to begin; Intermediate period treatment, namely to Symptomatic patient, takes certain method, from intervention, prevents or delay to subside, postpone or avoid carrying out prosthetic replacement, and this is the emphasis place of research at present; Later stage rescue therapy, also must not be the Therapeutic Method then taked, and after namely femur head necrosis is subsided, occurs Hip osteoarthritis, the hip arthralgia, moving obstacle, have impact on patients ' life quality, can only pass through joint replacement.Hip replacement wound is large, spends high.
The prior art the most close with this utility model is: early stage what subside, the elasticity of cartilage is fair, subchondral bone matter is not subsided, now remove sequestrum by operation, through decompression duct, insert eyelid retractor and support subchondral bone matter, improve capital resist collapse ability, preventer subsides, and by implanting autologous spongiosa bone, restarts the reparation potential of stock head internal skeleton.The device adopted and technology have patent No. ZL200810111686.6 and the patent No. to be the utility model patent of ZL2010202833869, wherein ZL200810111686.6 discloses a kind of eyelid retractor for femur head necrosis, its surface design is loose spongy, aperture is 100-800 micron, and axial portions is solid; It is a kind of for eyelid retractor netted in femur head necrosis that the patent No. is that the utility model patent of ZL2010202833869 discloses, its be made up of ti-ni shape memory alloy, have cancellated hollow out component, the profile of this component is consistent with femoral head intramedullary cavity, by changing temperature, can make it deformation occurs, be convenient to implant, after implantation, can be filled by its hollow cavity bone grafting, make interior netted eyelid retractor and New bone formation one, realize and strengthen capital effective support of subsiding, prevent or delay collapse of the femoral head necrosis.
Weak point is: the utility model patent of patent No. ZL200810111686.6, and this eyelid retractor aperture is less, and the bone trabecula of growing into is comparatively very thin, bears the limited use of pressure, and axial portions is solid, morely occupies space in limited marrow; Support function is not good enough, very limited to the effect preventing or delay femur head necrosis to subside, and uses less in recent years; The patent No. is the utility model patent of ZL2010202833869, required for this eyelid retractor, volume is little, is difficult to the establishment of memory alloy wire material, works out with thin memory alloy wire material, its support performance is limited, the experiment proved that the scheme of the interior netted eyelid retractor of employing memory alloy wire material is infeasible.
Utility model content
The technical problem that this utility model mainly solves is to provide a kind of bracing or strutting arrangement being used for the treatment of femur head necrosis, make it while improving the capital effective physical support that subsides, adding strong fix, the growth stress of osseous tissue can be reduced, patient is born a heavy burden healing ahead of time, and from improve blood for, reduce inaccessible pathology in pressure in marrow, dredging marrow and treat femoral head and continue to subside and downright bad, avoid carrying out prosthetic replacement, reduce patient suffering, reduce the financial burden, improve patients ' life quality.
For solving the problems of the technologies described above, the technical problem that this utility model mainly solves is to provide a kind of bracing or strutting arrangement being used for the treatment of femur head necrosis, and its material is Ti-Ni alloy, comprising: eyelid retractor and blade plate; Described eyelid retractor comprises, head, body and afterbody; Described head is the curved hemisphere returning shape with ditch, and described body is cylindric; Described head, body and afterbody are connected, and inside is hollow out, described head and body wall there is multiple hexagon hollow out through hole, described head becomes obtuse angle with body axis angle, described afterbody and body inwall are with mesh-supported, described mesh-supported is a hexagon honeycomb like structure, and in hexagon, separately have the one end on three limits to intersect at hexagonal center, and the other end on three limits is connected with hexagon nonadjacent vertices respectively; Described eyelid retractor head hemisphere is upwards put, and can realize and strengthen the capital effective support to subsiding; Be provided with drain rope in described eyelid retractor hollow cavity, in described mesh-supported, can pulp be poured into; Described blade plate and femur match, and which is provided with sleeve and multiple threaded locked holes; Described eyelid retractor body hollow pipe stretches out from afterbody, and extension is placed in the sleeve on blade plate.
Preferably, without through hole on described eyelid retractor extension wall, to improve extension intensity.
Preferably, described eyelid retractor extension end face is provided with cross recess.
Preferably, described eyelid retractor is combined with blade plate, while eyelid retractor can be made to locate, allows eyelid retractor activity within the specific limits again, and being beneficial to increases heavy burden, the growth healing at bone damage place and the buffering to pressure.
The beneficial effects of the utility model are: eyelid retractor is combined while improving the capital effective physical support that subsides, adding strong fix with blade plate, the growth stress of osseous tissue can be reduced, patient is born a heavy burden healing ahead of time, and from improve blood for, reduce inaccessible pathology in bone core pressure and dredging marrow and treat femoral head and continue to subside and downright bad, avoid carrying out prosthetic replacement, reduce patient suffering, reduce the financial burden, improve patients ' life quality.
