Description
Technical field
The invention belongs to orthopedic instrument technical fields, and in particular to meet body biomechanics structure, simple installation and at
This cheap bionical cooperation black box of high temporal shin bone-astragalus.
Background technique
People inevitably will receive unexpected fracture injury in daily production and life process.Such as sprain the ankle, or because of sprain the ankle
Caused by shin bone and the case where fracture of talus it is just very common.The relatively good processing of simple fracture, replacement and fixation.But if
Bones and joints end face defect caused by joint part is fractured, the equal serious damage of the bone of entire joint and combination sometimes, and have to more
It changes.With articular defect between shin bone lower end surface and astragalus, repaired with the replaceable prosthese of the prior art, not only initial stability
It is bad, and long-term bone uptake is also bad, and long-time stability are also bad.In particular, needing to replace the situation in joint, the prior art is used
Joint prosthesis is replaced together with the prosthese of astragalus end, then aforementioned drawback more highlights.The reason is that prosthetic joint face
Conformal performance it is poor, the connection structure of mating surface is unreasonable, leads to the generation of above-mentioned ill effect.The present inventor thinks for existing
The deficiency of technology, more meets ergonomic structure, and clinical use is easy, joint between conformal performance is good and resistance to affixed shin bone-astragalus
Black box replaces the prosthese of the prior art, is the optimal path for overcoming prior art defect.
For a long time, ankle fusion has always been considered as being treatment terminal phase ankle arthritis " goldstandard ".Close several
Year, ankle-joint displacement technique is challenging ankle fusion this " goldstandard ".The cardinal symptom of ankle arthritis patient shows
It is pain and dysfunction, reducing pain is the treatment most important Consideration of ankle arthritis.Ankle fusion and ankle-joint are set
Changing has good effect in terms of reducing patient pain.But joint replacement then more wins one in the function of retaining ankle-joint
It raises.Some researches show that compared to ankle fusion, the postoperative limping of patient of row ankle-joint displacement is reduced, and gait cycle is more
Normally.Ankle-joint displacement can rebuild ankle joint function, restore gait, mitigate pain.For the patient of terminal phase ankle arthritis,
Ankle-joint displacement selection again more for them.The present inventor thinks that for the deficiencies of the prior art exploitation more meets
Body biomechanics structure, clinical use are easy, and joint black box replaces showing between conformal performance is good and resistance to affixed shin bone-astragalus
There is the prosthese of technology, is the optimal path for overcoming prior art defect.
Summary of the invention
The purpose of the present invention is to provide one kind to meet ankle-joint biomethanics structure, simple installation and low-cost height
The bionical cooperation black box of conformal performance shin bone-astragalus.
The object of the present invention is achieved like this, a kind of bionical cooperation black box of high temporal shin bone-astragalus of the present invention,
Including tibial component, astragalus component and joint pad, the tibial prosthesis face of the tibial component and the shin bone on joint pad top are matched
Conjunction face matches, and the astragalus mating surface of joint pad lower part is matched with the astragalus articular surface of astragalus component；The tibial prosthesis
The arcwall face of body biomechanics design is pressed by face system, and the shin bone faying face of the tibial component is provided with to be tied with Tibial osteotomy face
The coupling structure of conjunction, the connection structure include real estate and side wing；The astragalus articular surface is also by human-body biological
The arcwall face of mechanics design, the astragalus faying face of the astragalus component are provided with the coupling structure in conjunction with astragalus osteotomy surface,
The coupling structure includes substrate, diagonal hold-down bars and fixed-wing；The shin bone mating surface of the joint pad presses human-body biological
Mechanics design concave ball shape cambered surface, the astragalus mating surface be provided with astragalus upper end replacement component cooperation under it is convex it
" V " shape fin.
The present invention is based on the designs of model of human ankle biomechanical principle, so that black box each portion in joint between shin bone-astragalus
Divide bionical cooperation more to meet ankle-joint biomechanical characterization, while guaranteeing joint pad and shin bone, astragalus or its replacement component cooperation
More proper, sliding is more smooth more mellow and fuller, and stability is more preferable, keeps bionical cooperation joint replaced " work " steady in a long-term, subtracts
The pain of few operation receiveing person.Clinical use of the present invention is convenient, is conducive to promote, and the postoperative function of patient restores good, and safety is on probation
Phase greatly extends.
