Abstract
The invention discloses a supporting device for the treatment of femoral head necrosis, and the device comprises a supporting apparatus and a bone fracture plate. The supporting apparatus comprises a head part, a body part, and a tail part. The head part is a bent hemisphere with gyrus, and the body part is cylindrical. The head part, the body part and the tail part are connected to form a body, and the interior of the body is hollow. The walls of the head part and the body part are provided with a plurality of hexagonal hollow-out through holes, and the inner walls of the tail part and the body part are provided with a mesh support. A hollow pipe of the body part extends outwards from the tail part. The bone fracture plate is matched with a femur, and is provided with a sleeve. During an operation, a necrotic bone tissue is removed at first, so as to place the supporting apparatus. The hollow pipe extends to the interior of the sleeve of the bone fracture plate, and bone putty is injected in the mesh support. A flow guide cable is buried in the hollow inner cavity of the supporting apparatus. The device improves the fixing of the bone fracture plate, enables a patient to bear a load and recover in advance, and achieves the treatment of femoral head necrosis from the pathology of blood supply improvement and the reduction of bone core pressure.
Description
Technical field
The present invention relates to a kind of support meanss for treating femur head necrosiss of hospital orthopedics.
Background technology
In existing clinical case, the common femur head necrosiss that are related to are mainly ischemic necrosis of femoral head (avascular
Necrosis of the femoral head, anfh) due to the Different types of etiopathogenises capital blood supply of destruction, make femoral head internal skeleton bad
An extremely caused pathological process, after osteonecrosis in femoral head, body carries out nature reparation, downright bad bone trabecula quilt to necrotic area
Progressively absorb, femoral head mechanical strength declines, and causes collapse-deformation, lead to the major injury of hip joint, support performance declines,
Under loading conditions, may result in subchondral bone to bear ABNORMAL STRESS, cause articular step-off, Hip osteoarthritis occur, sternly
Ghost image rings hip joint function, affects patients ' life quality.
Treatment to femur head necrosiss has Three models at present: early treatment, that is, the treatment being directed to the cause of disease and taking leads to
Cross bring vexation on oneself because, remove the cause of disease, this method is the most thorough, ideal, but in the cause of disease of femur head necrosiss, clearly or not
Clearly a lot, among currently many causes of disease are still in and probe into, etiotropic treatment is not more known where to begin；Intermediate period treatment, that is, right
Symptomatic patient, takes certain method, from intervention, prevents from or delays subsiding, postpone or avoid carrying out artificial joint
Displacement, this is the emphasis place of current research；Later stage rescue therapy, must not be also the Therapeutic Method then taken, i.e. femoral head
After necrosis is subsided, Hip osteoarthritis, the hip arthralgia, moving obstacle occur, have impact on patients ' life quality, Zhi Nengtong
Cross joint replacement.Hip replacement wound is big, spends high.
The prior art closest with the present invention is: early stage subsiding, the elasticity of cartilage is fair, and subchondral bone matter is not
Subside, remove sequestrum now by operation, through duct of reducing pressure, insert eyelid retractor and support subchondral bone matter, improve capital anti-
Subside ability, preventer subsides, by implanting autologous spongiosa bone, restart the reparation potential of stock head internal skeleton.Using device
And technology has the patent of invention of patent No. zl200810111686.6 and Patent No. zl2010202833869, wherein
Zl200810111686.6 discloses a kind of eyelid retractor for femur head necrosiss, and its surface is designed as loose spongy, hole
Footpath is 100-800 micron, and axial portions are solid；The patent of invention of Patent No. zl2010202833869 discloses a kind of use
Netted eyelid retractor in femur head necrosiss, it is being made up of ti-ni shape memory alloy, has cancellated hollow out component, this structure
The profile of part is consistent with femoral head intramedullary cavity, by changing temperature, you can be allowed to deform upon, is easy to implant, after implantation, permissible
Filled by its hollow cavity bone grafting, make interior netted eyelid retractor and New bone formation one, realize and strengthen to the femoral head subsiding
Effective support, prevent or delay collapse of the femoral head necrosis.
It is disadvantageous in that: the patent of invention of patent No. zl200810111686.6, this eyelid retractor aperture is less, grows into
Bone trabecula is more very thin, bears the limited use of pressure, and axial portions are solid, more occupy space in limited marrow；
Support function is not good enough, very limited to the effect preventing or delaying femur head necrosiss to subside, and uses less in recent years；The patent No.
Patent of invention for zl2010202833869, small volume required for this eyelid retractor it is difficult to the establishment of memorial alloy silk material, with thin
Memorial alloy silk material is worked out, and its support performance is limited, the experiment proved that the side of the interior netted eyelid retractor using memorial alloy silk material
Case is infeasible.
Content of the invention
The invention mainly solves the technical problem of provide a kind of support meanss for treating femur head necrosiss so as to
While improving the capital effective physical support that subsides, strengthen positioning, it is possible to decrease the growth stress of osseous tissue, patient is made to carry
Early healing of bearing a heavy burden, and from improve blood supply, reduce pressure in marrow, treatment femoral head continues to subside and bad inaccessible pathology in dredging marrow
Extremely, it is to avoid carry out prosthetic replacement, reduce patient suffering, reduce the financial burden, improve patients ' life quality.
For solving above-mentioned technical problem, the invention mainly solves the technical problem of provide one kind be used for treating femoral head bad
Dead support meanss, 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 linked to be
Integrally, and inside is hollow out, described head and body wall there are multiple hexagon hollow out through holes, described head and body axis
Wire clamp angle one-tenth obtuse angle, described afterbody and body inwall carry mesh-supported, and described mesh-supported is a hexagon honeycomb like structure,
And separately having the one end on three sides to intersect at hexagonal center in hexagon, the other end on three sides is respectively with hexagon not
Adjacent vertex is connected；Described eyelid retractor head hemisphere is put upwards, can achieve and strengthens to capital effective subsiding
Support；It is provided with drain rope in described eyelid retractor hollow cavity, pulp in described mesh-supported, can be poured into；Described blade plate and femur phase
Join, which is provided with sleeve and multiple threaded locked holes；Described eyelid retractor body hollow pipe stretches out from afterbody, and extension is put
In the sleeve on blade plate.
Preferably, no through hole on described eyelid retractor extension wall, to improve extension intensity.
Preferably, described eyelid retractor extension end surface is provided with cross recess.
Preferably, described eyelid retractor is used in combination with blade plate, while can making eyelid retractor positioning, allows eyelid retractor to exist again
A range of activity, be beneficial to increase bear a heavy burden, the growth healing at bone damage and the buffering to pressure.
The invention has the beneficial effects as follows: the raising that is utilized in conjunction with of eyelid retractor and blade plate is subsided capital effective physics
Property while support, strengthen positioning, it is possible to decrease the growth stress of osseous tissue, so that patient is born a heavy burden ahead of time healing, and from improve blood supply,
Reduce treatment femoral head on inaccessible pathology in bone core pressure and dredging marrow to continue to subside and necrosis, it is to avoid carry out artificial joint and put
Change, reduce patient suffering, reduce the financial burden, improve patients ' life quality.
