Abstract

The invention discloses a net-shaped supporting device. The net-shaped supporting device is used for the treatment of femoral head tissue necrosis, is made of titanium-nickel alloy, and comprises a head portion, a body portion and a tail portion. The head portion is semispherical, the body portion is cylindrical, external threads are formed in the outer side of the tail portion, and a cross groove is designed in the end of the tail portion; the head portion, the body portion and the tail portion are connected into a whole, and are hollow, and a plurality of through holes are formed in the wall of the head portion and the wall of the body portion. After necrotic osseous tissue in a femoral head medullary cavity is removed in the operation process, the net-shaped supporting device is placed into the femoral head medullary cavity, bone grafting filling is conducted on a hollow inner cavity of the net-shaped supporting device, and after bone substrates inside and outside the net-shaped supporting device heal, the whole can be formed. According to the net-shaped supporting device, effective supporting of a collapsed femoral head can be achieved and enhanced, continuous collapse and necrosis of the femoral head can be delayed or prevented, prothesis replacement is delayed or avoided, the pain of a patient is relieved, the economic burden is reduced, and the living quality of the patient is improved.

Description

A kind of mesh-supported device
Technical field
The present invention relates to a kind of mesh-supported of hospital orthopedics, for the necrosis therapeutic of femoral head tissue.
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 the present invention 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 patent of invention 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 patent of invention 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 patent of invention 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 patent of invention 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.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of mesh-supported device, make it can realize and strengthen capital effective support of subsiding, delay or prevent femoral head from continuing to subside and necrosis, delay or 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 the present invention mainly solves is to provide a kind of mesh-supported device, and its material is Ti-Ni alloy, comprising: head, body and afterbody three part, described head, body and afterbody are connected as a single entity and inside is hollow out.
Preferably, described head is hemispherical, described body is cylindric, and there is external screw thread in described lateral tail face, described tail end face design cross recess; Described head and body wall there is multiple through hole.
Preferably, described head hemisphere hollow out and in netted after being provided with through hole.
Preferably, after described device implanted femur incidence, bone grafting can be made to hollow cavity and fill, can becoming to be integrated after sclerotin healing inside and outside described device, can realizing and strengthen the capital effective support to subsiding.
The invention has the beneficial effects as follows: can realize and strengthen capital effective support of subsiding, delay or prevent femoral head from continuing to subside and necrosis, delay or avoid carrying out prosthetic replacement, reducing patient suffering, reduce the financial burden, improving patients ' life quality.
