Abstract
The invention discloses an implantable bone support. The structure of the bone support comprises a top disc and a plurality of fins, wherein upper ends of the fins are connected to the top disc; and the fins are vertical to the top disc. The support is beneficial to growth and sufficient fusion of new bones, and has an excellent support effect, so that the support can be used for treating large-area osteonecrosis and bone collapse caused by the large-area osteonecrosis to play effects of relieving pains, repairing internal structures of bones and recovering functions of bones. The implantable bone support not only can be used for treatment of femoral head necrosis, but also can be used for treatment of osteonecrosis of other parts.
Description
Technical field
The present invention relates to osteonecrosis treatment technology field, specifically a kind of implanted subcutaneous support.
Background technology
In the prior art, implant eyelid retractor to bone cavity and be used to treat the bone that femur head necrosis causes and subside.Chinese patent CN2699849 discloses a kind of femur head necrosis and has supported therapeutic apparatus, and it is to be made up of Ni-Ti alloy bracket, and support is hugs empty tennis shape, constitutes through the wire cross establishment.The eyelid retractor that this employing memorial alloy is processed because of not enough so that its structure and the shape when recovering typing of its deformability, so can not play due therapeutical effect behind the implant into body.
Summary of the invention
The object of the invention will provide a kind of implanted subcutaneous support exactly, to solve the problem of subsiding that osteonecrosis causes, alleviates the pain that is caused by osteonecrosis, repairs the inside bone structure, with effective treatment osteonecrosis in a big way.
The present invention is achieved in that the implanted subcutaneous support comprises taking over a business with the upper end and is connected in said some fins of taking over a business.
The implanted subcutaneous support that the present invention designed, it takes over a business the formation supporting surface, and fin constitutes support claw, therefore, can form effective support to surface of bone in the implantable bone.In addition, take over a business with connected downward fin to have constituted open open space, the growing space of implanting new bone behind the bone cavity is provided, new bone and eyelid retractor are merged better, thereby effectively improve therapeutic effect.And the slit that exists between each fin is set up blood fortune also for new bone passage is provided.Thus, green bone, new bone and eyelid retractor form three-dimensional the combination, thereby significantly improve therapeutic effect.
Under technique scheme, the present invention can realize like this:
In the said implanted subcutaneous support, said fin with said take over a business vertical.Adopt this structure, help the smooth implantation of eyelid retractor.Can be after implantation by apparatus with supportting outside the fin lower ends, to increase its stability of strutting system.
Said fin lower ends is circular-arc.
Saidly take over a business to be circle.
Saidly take over a business the center and have manhole, said through-hole wall is shaped on screw thread.
Said fin is the 8-14 sheet.
Eyelid retractor of the present invention not only helps the growth of new bone and the abundant fusion of new bone; And its support effect is good, and therefore, this eyelid retractor can be used for treating large-area osteonecrosis and the bone that caused subsides. play alleviating pain; Repair the inside bone structure, recover the effect of bone function.The present invention not only can be used for the dead treatment of femur headring, also can be used for the treatment of other position osteonecrosis.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 struts the back structural representation for the present invention.
The specific embodiment
Eyelid retractor of the present invention can adopt metal tantalum to process.Structure is as shown in Figure 1, and the implanted subcutaneous support comprises that circular head plate 1 and upper end are connected in said some fins 2 of taking over a business.Consider that from the rigidity of fin itself, formed support degree aspect said fin sheet number can be the 8-14 sheet, is preferably the 10-12 sheet.Said fin 2 can be taken over a business 1 and extends (shown in Figure 1) vertically downward with said, also can flare to extending below (shown in Figure 2).To be fin 2 take over a business 1 vertically with said embodiment preferably, after implantation, by apparatus support outside the fin lower ends opened again, forms structure shown in Figure 2, so both has been convenient to the operation of implantation process, also can increase the stability of strutting system after its implantation.
In the eyelid retractor of the present invention, preferably embodiment be said fin lower ends is made as circular-arc, to avoid that surrounding tissue is caused damage.
Implanted subcutaneous support of the present invention,, said center of taking over a business has manhole 3, and said through-hole wall is shaped on screw thread, through this through hole specific purpose tool that can spin, so that fin is opened.
The eyelid retractor that the present invention designed is gone when strutting after implanting bone cavity again, can control the degree of strutting according to the size of necrosis area in the bone, can effectively fill the bone internal cavity, also can play effective supporting.And the open type inner chamber plays bone trabecular effect, makes the fresh bone ramp, fills and repairs femoral head, and then play the efficacious therapy effect.Use the present invention to be used for the treatment of osteonecrosis of femoral head, can postpone or avoid saw to remove femoral head, postpone and avoid carrying out the femoral head replacement operation.Make patient keep femoral head most possibly, thereby, bring glad tidings to patient for patient palliates the agonizing sufferings.
When eyelid retractor of the present invention was used for the dead treatment of bone thigh headring, method for using was: the tunnel of setting up enough diameters at the neck of femur place; Reduce pressure through the tunnel after setting up the tunnel, remove sequestrum, set up suitable covering of the fan space; Implant eyelid retractor of the present invention; Eyelid retractor is strutted suitable size; Bone grafting is filled.
