Abstract
The utility model relates to an implanted bone supporting device good in biocompatibility. The implanted bone supporting device comprises a top disc (1) and a plurality of fins (2), wherein the upper ends of the fins (2) are connected to the top disc (1), and a plurality of holes are formed in the fins at intervals. The supporting device facilitates new bone growth and sufficient new-bone combination and is good in supporting effect, the biocompatibility of the bone supporting device is greatly improved, the mechanical property of the bone supporting device is well satisfied, the service life of the bone supporting device is greatly prolonged, and the implanting comfort of the bone supporting device is greatly improved.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, is specifically related to a kind of Implantable bone support of good biocompatibility.
Background technology
In prior art, to bone cavity, implant eyelid retractor and be used for the treatment of 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 consist of Ni-Ti alloy bracket, and support is hugs empty tennis shape, works out formation by wire cross.The eyelid retractor that this employing memorial alloy is made, because of not enough so that its structure and the shape while recovering typing of its deformability, so can not play due therapeutical effect after implant into body.And adopt Ni-Ti alloy as the subcutaneous support material, it is metal material, and the time has been grown, thereby there will be and repel the service life that affects subcutaneous support with tissue.
The purpose of this utility model is to provide a kind of Implantable bone support of good biocompatibility, the problem of subsiding caused to solve osteonecrosis, alleviate the pain caused by osteonecrosis, repairs the inside bone structure, effectively to treat osteonecrosis in a big way, and make it have good biocompatibility.
The purpose of this utility model is achieved in that
A kind of Implantable bone support of good biocompatibility, comprise taking over a business, and upper end is connected in described some fins of taking over a business; Described fin is the porous product.
This Implantable bone support, it takes over a business the formation supporting surface, and fin forms support claw, can form effective support to surface of bone in implantable bone.In addition, take over a business with connected downward fin and formed uncovered open space, the growing space of implanting new bone after bone cavity is provided, new bone and eyelid retractor are merged better, thereby effectively improve therapeutic effect.And the gap existed 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 combination, thereby significantly improve therapeutic effect.
Above-mentioned fin, preferably adopt the porous tantalum product.Find that through studying for a long period of time porous tantalum spare, in the biocompatibility that has greatly improved subcutaneous support, has also well met its mechanical property, greatly improved its service life and implanted comfort level.Above-mentioned porous tantalum product, can adopt the preparations such as foam dipping method, die pressing, and its porosity is 60 ~ 70%.
Further, in above-mentioned Implantable bone support, described fin with described take over a business vertical.Adopt this structure, be conducive to the smooth implantation of eyelid retractor.After implantation, can will outside fin lower ends, be supportted by apparatus, to increase its stability of strutting system.
Above-mentioned fin lower ends is circular-arc.Above-mentionedly take over a business to be circle.
Above-mentionedly take over a business center and have manhole, above-mentioned manhole inwall is shaped with screw thread.
Above-mentioned fin is the 8-14 sheet.
The utlity model has following beneficial effect:
This eyelid retractor not only is conducive to the growth of new bone and the abundant fusion of new bone, and its support effect is good.It can be used for treating large-area osteonecrosis and the bone that causes subsides, the effect of play alleviating pain, repairing the inside bone structure, recovering the bone function.This utility model not only can be used for the treatment of femur head necrosis, also can be used for the treatment of other position osteonecrosis.And be set to porous tantalum spare by fin, and greatly improved the biocompatibility of this subcutaneous support, also well met simultaneously its mechanical property, greatly improved the service life of this subcutaneous support and implanted comfort level.
The accompanying drawing explanation
Fig. 1 is the structural representation of the Implantable bone support of good biocompatibility described in this utility model embodiment 1.
Fig. 2 is the structural representation after the Implantable bone support of structure shown in Figure 1 struts.
The specific embodiment
Be below this utility model preferred embodiment, be not intended to limit protection domain of the present utility model.
Embodiment 1
As shown in Fig. 1～2: a kind of Implantable bone support of good biocompatibility comprise taking over a business 1, and upper end is connected in 1 fin 2; Fin 2 is the porous tantalum product, and its porosity is 60 ~ 70%; Fin 2 lower ends are circular-arc, have 14, and fin 2 is with to take over a business 1 vertical; Take over a business 1 for circular, and take over a business 1 center and have manhole 3, these manhole 3 inwalls are shaped with screw thread.
This eyelid retractor is gone while strutting again after implanting bone cavity, can control the degree of strutting according to the size of necrosis area in bone, can effectively fill the bone internal cavity, also can play effective supporting role.And the open type inner chamber plays bone trabecular effect, make the fresh bone ramp, fill and repair femoral head, and then play effective therapeutical effect.Use the treatment of this utility model for osteonecrosis of femoral head, can postpone or avoid saw except femoral head, postpone and avoid carrying out the femoral head replacement operation.Make patient retain most possibly femoral head, thereby, for patient palliates the agonizing sufferings, bring glad tidings to patient.
When eyelid retractor of the present utility model was used for the treatment of osteonecrosis of femoral head, using method was: the tunnel of setting up enough diameters at the neck of femur place; After setting up tunnel, reduce pressure by tunnel, remove sequestrum, set up suitable covering of the fan space; Implant eyelid retractor of the present utility model; Eyelid retractor is strutted to suitable size; Bone grafting is filled.
Claims (3)
