Abstract
The utility model discloses a strutting piece for treating ischemic necrosis of a femoral head, which is composed of a hollow netted sphere shaped Ni-Ti alloyed bracket composed of cross-knitted wires. The utility model has simple structure, convenient operation and usage, and high safety. Because the netted sphere bracket composed of the Ni-Ti alloy has super elastic property and well biology compatibility, the effect of the utility model applied to treat adult ischemic necrosis of femoral head is obvious. Implanting the utility model into the femoral head has the function of powerful support and rebuilding the blood movement of the femoral head, effectively preventing the collapse of the femoral head.
Description
Technical field: this utility model belongs to the orthopaedic medical treatment technical field, relates to a kind of support that is used for the ischemic necrosis of femoral head treatment.
Background technology: ischemic necrosis of femoral head of adult is the orthopaedics commonly encountered diseases, and the patient takes action limited, and health is very painful.The cause of disease of ischemic necrosis of femoral head mainly is owing to ischemic femoral head causes femur head necrosis, the collapse of the femoral head that the stressed heavy burden of femoral head causes.At present, clinical general employing operative treatment.As core decompression add that bone grafting, blood vessel are implanted, band muscle flap or vascular pedicle bone lobe implant and various bone-culting operation, with the capital blood fortune of try reconstruct, capitally further subsides but all can't stop, its reason is mainly due to lacking strong support in the femoral head.
Summary of the invention: the purpose of this utility model provides a kind of ischemic necrosis of femoral head treatment and supports, and it is implanted in the femoral head of ischemic necrosis, plays strong supporting role and rebuilds capital blood fortune, prevents capital subsiding.
For achieving the above object, the treatment of this utility model ischemic necrosis of femoral head is supported, and is made of the Ni-Ti alloy bracket, and support is the tennis shape of hollow out, constitutes by the wire cross establishment.
Said tennis diameter is 10～40mm.
Said diameter wiry is 0.7～2mm.
Said tennis is spherical shape or oval spherical.
The two ends of said tennis are provided with support ring.
This utility model is simple in structure, easy for operation, safe and reliable, because the tennis support that the Ni-Ti alloy constitutes, have super characteristic and the good biocompatibility of playing, it is obvious to be applied in treatment ischemic necrosis of femoral head of adult disease effects, with playing strong supporting role in its implanted unit bone and rebuilding capital blood fortune, has effectively prevented capital subsiding.
During the operation implant frame, outside otch exposes femoral head before selecting, window at femur head and neck intersection, strike off the necrotic bone in the femoral head, utilize the super bullet characteristic and the good biocompatibility of Ni-Ti alloy, with can be in the tennis support implanted unit bone, effectively prevent from capitally further to subside with the bone jack-up of subsiding; And then ilium, spongy bone and the band of getting homonymy revolve the dark vessel pedicle bone of bone bone lobe and implant one by one in the tennis support, the bone lobe can grow to femoral head in the mesh of tennis support, thereby rebuild capital blood fortune, treated the disease of femur ischemic necrosis completely.
Description of drawings: Fig. 1 is this utility model structural representation;
Fig. 2 is another example structure sketch map of this utility model.
The specific embodiment: with reference to the accompanying drawings, the treatment of this utility model ischemic necrosis of femoral head is supported, and is made of the Ni-Ti alloy bracket, and support is the tennis shape of hollow out, intersects to work out by tinsel 1 to constitute; The tennis diameter is 10～40mm; The diameter of tinsel 1 is 0.7～2mm; Tennis is spherical shape or oval spherical; The two ends of tennis are provided with support ring 2, and tinsel 1 intersection is organized on the support ring 2 at tennis two ends.
