Abstract
The utility model provides a memory metal support for the head of a femur. The support of the utility model is a hollow circular or oval reticular ball, two top ends of the reticular ball can be provided with support rings on which one or a plurality of metal wires are crossly woven and wound, and memory metal is Ni-Ti alloy. The utility model has the advantages of simple structure, convenient operation and use, safety and reliability; the utility model strongly performs a supporting function when implanted in the head of a femur, and can help to restore the blood circulation of the head of the femur so as to prevent the further collapse of the head of the femur.
Description
This utility model relates to a kind of femoral head memory metal support that is used for the femoral head treatment.
Adult thighbone ischemic necrosis (AVN) is the orthopaedics commonly encountered diseases, gets this sick patient and takes action limitedly, and health is very painful, and that this disease deals with is very thorny, generally adopts the method for various operations to treat.The cause of disease of femur ischemic necrosis causes femur head necrosis mainly due to ischemic femoral head, and the stressed and heavy heavy burden that produce of femoral head causes that femoral head steps on sunken.Since the nearly century, people adopt core decompression to add bone grafting, and blood vessel is implanted, and band muscle flap or lobe transplanting of band blood vessel bone and various osteotomies etc. are with the capital blood fortune of try reconstruct, but all can't stop and capitally further subside, its reason is many owing to lack strong support in the femoral head.
The purpose of this utility model provides a kind of femoral head memory metal support at the deficiencies in the prior art exactly, in the femoral head of its implantable ischemic necrosis, effectively play a supporting role, and can assist to rebuild capital blood fortune, prevent from capitally further to subside.
The purpose of this utility model is achieved in that a kind of femoral head memory metal support, the netted ball of the hollow out that its support can be, and it can work out coiling by wire cross.
The maximum gauge of described netted ball can be 35mm, and minimum diameter can be 15mm.
Described diameter wiry can be 0.7mm to 2mm.
Described netted ball can be circle or ellipse.
Described tinsel can be one or more.
Can there be support ring on two tops of described netted ball.
This utility model is simple in structure, easy for operation, safe and reliable, it is remarkable that super bullet characteristic that it has and excellent biological compatibility are applied on the treatment adult thighbone ischemic necrosis effect, because it is effectively played a supporting role in implanted unit bone, and can assist to rebuild capital blood fortune, prevent from capitally further to subside.
Below in conjunction with accompanying drawing and specific embodiments this utility model is described in further detail.
Fig. 1 is a kind of example structure sketch map of this utility model;
Fig. 2 is the another kind of preferred embodiment structural representation of this utility model;
The Ni-Ti alloy is to be made of a certain proportion of nickel and titanium, it is except having the stable morphology memory effect, also have a kind of elasticity that produces by the atom site change that is different from, be called super-elasticity, general elastomeric material, as stainless steel silk, copper alloy spring wire etc., its strain is no more than 0.5%, and the strain of Ni-Ti alloy exceeds them more than 10 times, even severally decupling general elastomeric material, this utility model utilizes memory metal to have the super characteristic that plays exactly.
Referring to Fig. 1, this utility model is the embodiment that the top has support ring memory wire support.Memory metal is the Ni-Ti alloy.Its support is the circular or oval netted ball of hollow out, and can there be support ring 2 on two tops of netted ball, and one or more tinsel 1 interlacing is wrapped on the support ring 2.
Referring to Fig. 2, this utility model is the embodiment of support that does not have the memory wire coiling of support ring.Its support also can be the circular or oval netted ball of hollow out, is entwined by one or more tinsel 1 interlacing.
Maximum gauge according to the netted ball of different actual needs can be 35mm, and minimum diameter can be 15mm, and diameter wiry can be 0.7mm to 2mm.
During the operation implant frame, outside otch exposes femoral head before selecting, window at femur head and neck intersection, strike off necrotic bone in the femoral head, utilize memory metal super-elasticity, in netted ball stand implanted unit bone, netted ball stand is the femoral head that subsided of jack-up well, prevents that effectively it from subsiding.Get homonymy ilium spongy bone and band and revolve the dark vessel pedicle ilium of ilium bone lobe and implant one by one in the netted ball stand again, the bone lobe can grow to femoral head from the mesh of netted ball stand, has therefore rebuild capital blood fortune, has treated the disease of femur ischemic necrosis up hill and dale.
So far treat AVN patient's 3 examples from March, 1997, obtained satisfactory effect
