Description
Technical field
The invention belongs to orthopedic instrument technical fields, and in particular to a kind of high flexibility ratio that is structurally reasonable, being equipped with simplicity is imitative
Life is all referring to joint replacement part.
Background technique
People inevitably will receive in daily production and life process and surprisingly cause palm bone and phalangeal fracture, or because
The diseases such as rheumatoid lead to palm articulations digitorum manus limitation of activity, or even lose normal physiological function.Best improvement metacarpophalangeal joints
The therapeutic modality of function is exactly that artificial prosthesis progress joint replacement is still replaced, not only initial stability with existing prosthese
It is bad, and Bone Ingrowth is bad causes long-time stability also bad.With carrying out long term follow-up, aforementioned disadvantage after existing prosthesis replacement
End more highlights, so not designing a kind of metacarpophalangeal joints prosthese of maturation yet.The reason is that prosthetic joint face
Conformal performance is poor, and the connection structure of faying face is unreasonable, and marrow inner part stability is poor, leads to the generation of above-mentioned ill effect.This hair
For the deficiencies of the prior art, exploitation more meets body biomechanics structure to bright people, and mechanical engagement is good, low in cost, conformal
Property good and resistance to affixed Bionic fingers joint replacement component instead of the prosthese of the prior art be overcome prior art defect effective
Mode.
Summary of the invention
The purpose of the present invention is to provide one kind more to meet body biomechanics structure, and mechanical engagement is good, low in cost
The bionical metacarpophalangeal joints Replacement Part of high flexibility ratio.
The object of the present invention is achieved like this, and the bionical high flexibility ratio all referring to joint replacement part includes joint ontology
With connector in marrow, the joint ontology is divided into proximal joint body and distal joint body, and the joint body top surface is to close
The top surface of nodal section structure, i.e., described proximal joint body and distal joint body respectively with the working face articulation of joint spacer
Cooperation, the proximal joint body or distal joint body press body biomechanics and anatomical structure designs, bottom end setting
Connector in marrow, connector is separate assembling vertebra shape structure in the marrow.
The present invention is based on body biomechanics principle, the conformal performance of the bionical metacarpophalangeal joints displacement component of exploitation is more preferable, closes
Abridged edition body is stronger in conjunction with osteotomy surface.The present invention more meets body biomechanics structure, and mechanical engagement is good, low in cost,
Clinical applicability is good, and the postoperative function of patient restores good, and the safe trial period greatly extends.
