Description
Technical field
This utility model relates to a kind of orthopaedics and uses artificial joint, particularly a kind of buffer-type surface type knee joint.
Background technology
At present, orthopaedics is widely used with artificial joint, has solved the difficult problem of many orthopaedics patients.But existing artificial knee joint does not have pooling feature, cause produce between articular prosthesis very stiff and demanding to impulse force easy abrasion joint.In the artificial knee joint operation, because adopt large platform to cut bone, bone is many, damage is big so cut, and causes the bone planting effect poor, is prone to produce the interface, causes joint loosening.
Summary of the invention
The purpose of this utility model is to overcome the deficiency of prior art, provide a kind of reasonable in design, reduce hard collision and the good buffer-type surface type knee joint of bone planting effect between articular prosthesis.
This utility model solves its technical problem and takes following technical scheme to realize:
A kind of buffer-type surface type knee joint is connected and composed by condyle of femur prosthese, butterfly-shaped activeness flat surface, butterfly-shaped tibial plateau prosthese pedestal, tibial plateau implantation body and the buffering vibration absorber that is installed on the butterfly-shaped tibial plateau prosthese pedestal; The medial surface of described condyle of femur prosthese is provided with to preventing the reinforcement of condyle of femur prosthese distortion, and the rear end is arranged with a pair of bone grafting storehouse; The middle bottom surface of described butterfly-shaped activeness flat surface is provided with ultra radius sphere hole; The positive middle part of the front end of described butterfly-shaped tibial plateau prosthese pedestal is provided with ganoid spherical stake; Front end symmetry in spherical stake is equipped with a pair of limited post that can play the spin function of joint position-limiting action; Rear end in spherical stake is arranged with a pair of shock absorber hole that is used to install buffering vibration absorber, and bottom centre's implant of described butterfly-shaped tibial plateau prosthese pedestal is the cylindrical fireworks shape; Described tibial plateau implantation body be the loose structure of hollow post jamb and in the top horizontal plane be provided with threaded hole.
And described condyle of femur prosthese is the structure of inside and outside two condyle interconnection system flexing tracks of femur >=130 °.
And the front end of described condyle of femur prosthese is for having trochlear surface or not having trochlear surface.
And described buffering vibration absorber is made up of bumper post, buffer body and buffering material, and this bumper post is installed in the upper end of buffer body, and this padded coaming is installed in the buffer body.
And described butterfly-shaped activeness flat surface adopts the supra polymer material to process.
And the bottom surface of described butterfly-shaped tibial plateau prosthese pedestal is processed by metal material.
The advantage and the good effect of this utility model are:
1, this utility model is according to human body knee joint special physiological FM and biomechanics characteristic; Adopt the principle of motion simulation machinery combination to form; The anatomic tissue relation can better keep its integrity before making shin; Also be the minimum operation designing of present similar operation amputation osseous tissue, kept more osseous tissue before the shin not because of the displacement of prosthese by too much amputation, solved the problem that prior art exists.
2, the rear end, platform both sides of this utility model is provided with original elastic buffering mechanism, has reduced the liquidating property stress that is produced when moving between the prosthese effectively, thereby has played the joint motions buffering, reduces its coefficient of friction, has prolonged the service life of prosthese.
3, this utility model has solved bone through tibial plateau implantation body and has inlayed problem, makes prosthese implant the back and is difficult for looseningly, and good stability has biological plantation function.
4, this utility model meets kneed sport dynamics requirement more, further improves medical effect.
