The invention discloses a sectional adjustable artificial hip joint prosthesis. The sectional adjustable artificial hip joint prosthesis comprises a handle-shaped body capable of being inserted into the femoral myelocavity, the lateral upper part of the handle-shaped body extends, an included angle between the axis of an extension end and the axis of the handle-shaped body is 110-140 degrees, the end part of the extension end is connected with a globoid matched with the acetabulum, the handle-shaped body is in an integrated structure or a meshed insertion structure, one end of the extension end is hinged with or fixedly connected with the globoid, and the other end of the extension end is hinged with the handle-shaped body. When the hip replacement operation is carried out clinically, the adjustment on the collodiaphyseal angle and the femoral neck anteversion is conveniently realized when different thighbone patients wear the hip joint prosthesis, while hip replacement is realized, dissection imbedding and fixation are realized, individual differences of the people are perfectly adapted, the hip replacement curative effect is improved, the accurate medical treatment is realized, and postoperative complications are further reduced.
Description
Technical field
The present invention relates to articular prosthesis.
Background technology
Fracture of femoral neck can betide each age group, but the most common with the old people of more than 50 years old, and women is more than male.Young and middle-aged fracture of femoral neck is often caused by larger external force.The disability rate of fracture of femoral neck and fatality rate are all higher, have become one of chief threat causing life of elderly person Quality Down or death.For there being the current multirow hip replacement clinically of the patient of surgical indication, this technology is increasingly mature and universal, and its 10 years acceptance rates are more than 90%.Artificial hip prosthesis have passed through the development of more than 70 year, now be widely used in clinical, from initial Teflon material high duty metal finally to metal material, the hip prosthesis of human anatomy is met from the most original hip joint model height finally, artificial hip prosthesis its structure of anatomical structure terms of mechanics and normal human's structure quite close, its wearability, neural autonomous perceptibilities etc. are all higher, surrounding bone tissue resorption also can be made to reduce to minimum, these all have the functional rehabilitation activity after to operation in patients to have positive role, its good pain improvement rate makes the quality of life of patient greatly improve, range of motion also greatly improves, for improving patient's long-term prognosis, there is positive role.
Although experienced by improvement larger several times, but because neck of femur shape is comparatively special, two particularity angle collodiaphyseal angles (being about 110 ° ~ 140 °) and top rake (being normally 12 ° ~ 15 °), how different because of individual differences, existing artificial hip prosthesis, owing to adopting integrated fixed structure, thus perfectly cannot adapt to above-mentioned individual variation.And during current clinical up hip replacement, artificial hip prosthesis inserts experience and the sensation that angle also mainly relies on patient, namely the slightest difference likely causes the peculiar defect of some hip replacements, as caused prosthetic loosening and secondary fracture, osteonecrosis etc., even also have some rare but problems of objective reality, as inserted the fracture of prosthese central stabilizer support, waist muscle expands.Therefore a kind of collodiaphyseal angle and the adjustable artificial hip prosthesis of top rake is is urgently researched and developed.
Summary of the invention
The invention provides a kind of stepwise adjustable joint formula artificial hip prosthesis, to overcome the drawback that prior art exists.The object of the invention realizes in the following manner:
This stepwise adjustable joint formula artificial hip prosthesis comprises a pluggable handle body in femoral bone cavitas medullaris, extend above the side of handle body, between elongated end axis and handle body axis, angle is 110 ° ~ 140 °, the end of elongated end connects a spheroid matched with acetabular bone, it is characterized in that described handle body is integral type structure or engagement type connected structure, the company of strand or be connected between one end of described elongated end and described spheroid, is hinged between the other end of elongated end and described handle body.
Described spheroid lower end is a slotting falcon structure, and the end of described elongated end is a slot matched with described slotting falcon, inserts strand between falcon and slot and connects, slot is coated with clench nail.
Described spheroid lower end is a groove type structure, and the end of described elongated end is the spheroid of one and described groove diameter compatible, is hinged between the end of elongated end and described spheroid.
The technological progress that the present invention obtains: because handle body and handle body change engagement type grafting adjustable structure into by original integral type handle body, make handle can realize sagittal plain in this junction point to rotate, again due between one end of elongated end and spheroid for the strand of inserting falcon and slot links structure, namely the connection between neck of femur prosthese and femoral head prosthesis is twist-style syndeton, simultaneously due to the hinge structure between handle body elongated end and handle body, make elongated end and neck of femur connect point in this strand and realize Coronal rotation, clinically during row hip replacement, the twist-style connection angle between slotting falcon and slot and the hinge angle between handle body elongated end and handle body can be adjusted according to patient individual difference, conveniently realize the adjustment of collodiaphyseal angle and top rake when different femur patient installs hip prosthesis, greatly can improve and insert due to prosthese the prosthetic loosening and secondary fracture that angle brings, osteonecrosis, prosthese central stabilizer support ruptures, waist muscle such as to expand at the peculiar defect of hip replacement, post-operative complication can be reduced further, hip replacement can be made to obtain anatomical reduction and firm internal fixtion simultaneously, can the individual variation of perfect adaptation population, improve hip replacement curative effect, realize precisely medical treatment, operation in patients posterior joint mobility and quality of life can be made to be greatly enhanced, to functional rehabilitation after operation in patients and improve patient's long-term prognosis there is outstanding facilitation.
