Abstract
An umbrella-shaped memory alloy supporter for a femur head comprises an umbrella-shaped supporter and a support sleeve, wherein the lower end of the umbrella-shaped supporter is connected with the support sleeve in a sleeved mode through umbrella handles, the umbrella-shaped supporter is composed of eight support umbrella ribs, and the support sleeve is made of plates through rolling process. Blood circulation holes are arranged on the sleeve wall of the support sleeve and anti-dropping inverted teeth are arranged on the outer surface of the support sleeve. The umbrella-shaped memory alloy supporter inside the femur head can not only have a strong supporting role, but also assist to reconstruct blood circulation of the femur head and prevent further collapse of the femur head so that pains of a patient are relieved. By the aid of the umbrella-shaped memory alloy supporter, operative time is shortened, operative procedure is simplified, support is safe and reliable, and remarkable effects on curing adults' femur head collapse caused by femoral head avascular necrosis are achieved. The umbrella-shaped memory alloy supporter is simple in technical modeling, easy to be imbedded after deformation and stable in mounting after shape recovery, and is convenient in use, and firm and reliable in fixation during an operation.
Description
Technical field
This utility model relates to medical apparatus and instruments, and particularly surgery, orthopaedics are used for being implanted at femoral head, can well supporting the capital a kind of umbrella memorial alloy femoral head eyelid retractor that has subsided.
Background technology
Generally adopt core decompression to add operation methods such as bone grafting, blood vessel implantation, osteotomy at present, the capital blood of try reconstruct fortune owing to lack strong support in the femoral head, all can't stop and capitally further subside.Especially osteotomy has further damaged the residual blood fortune of femoral head, and all there be subsiding in various degree in the later stage.Femoral head memory metal support adopts wire cross establishment coiling, and its support force is weak, less stable.
The utility model content
Technical problem to be solved in the utility model provides a kind of by be implanted into a femoral head eyelid retractor at femoral head, support the femoral head that has subsided, and assist to rebuild capital blood fortune, prevent a kind of umbrella memorial alloy femoral head eyelid retractor that femoral head further subsides.
Technical problem of the present utility model adopts following technical proposals to solve:
A kind of umbrella memorial alloy femoral head eyelid retractor is made up of umbrella eyelid retractor and stop sleeve, and umbrella eyelid retractor lower end is by umbrella handle and stop sleeve socket.
Described umbrella eyelid retractor is made up of 8 supporting umbrella bones.
Described stop sleeve adopts sheet material to roll and forms, and is distributed with blood fortune hole on the barrel of stop sleeve, and the stop sleeve outer surface is provided with the anti-pawl that withdraws from.
This utility model is by being implanted into a umbrella memorial alloy femoral head eyelid retractor at femoral head, the umbrella eyelid retractor not only can well support the femoral head that has subsided, and can pass through umbrella frame gap implantable bone lobe, the bone lobe can be from the interstital growth of umbrella frame to femoral head, therefore eyelid retractor not only plays strong supporting role in femoral head, and can assist to rebuild capital blood fortune, and prevent from capitally further to subside, reduced the many miseries of patient; And shortened operating time, simplified operation technique, support safety is reliable, and the collapse of the femoral head effect that treatment adult thighbone ischemic necrosis is caused is remarkable.This utility model art shapes is simple, and easily deformable inserting installed stable after the complex.Easy to use in operation, fixation, reliable.Present technique has excellent application value and application prospect, and rational Application can obtain satisfactory effect, compares the quality of life that more helps to improve the patient to a certain extent with osteotomy with operations such as bone graftings, has good economic and social benefit.

The specific embodiment
Below in conjunction with accompanying drawing this utility model is described in further detail:
A kind of umbrella memorial alloy femoral head eyelid retractor is made up of umbrella eyelid retractor 1 and stop sleeve 2, and umbrella eyelid retractor 1 lower end is by umbrella handle 4 and stop sleeve 2 sockets.By the umbrella eyelid retractor 1 that 8 supporting umbrella bones 3 are formed, utilize the memory characteristic of memory alloy material, the persistent pressure function after shape is recovered helps umbrella eyelid retractor and interior tight the contact and support of femoral head.Stop sleeve 2 adopts sheet material to roll and forms, be evenly distributed with blood fortune hole 5 on the barrel of stop sleeve 2, stop sleeve 2 outer surfaces have the anti-pawl 6 that withdraws from, implanting the back umbrella handle inserts in the sleeve, play a supportive role jointly with the umbrella eyelid retractor, strengthen the stability of umbrella memorial alloy femoral head eyelid retractor and increase support force, finish the function of support jointly.After this umbrella memorial alloy femoral head eyelid retractor is implanted, in femoral head, not only play strong supporting role, and can assist to rebuild capital blood fortune, prevent from capitally further to subside, alleviate the patient suffering.
The manufactured materials of this umbrella memorial alloy femoral head eyelid retractor is selected for use has the temperature memory function in the prior art, the material that has excellent biological compatibility simultaneously, as Ti-Ni marmem, extensive use in clinical, safe in vivo, nontoxic, nothing rejection.
