Description
Technical field
The present invention relates to articular prosthesis。
Background technology
Fracture of femoral neck can betide each age group, but the old people with more than 50 years old is the most common, and women is more than male。Young and middle-aged fracture of femoral neck is often caused by bigger external force。The disability rate of fracture of femoral neck and fatality rate are all higher, it has also become cause one of chief threat of life of elderly person Quality Down or death。The current multirow hip replacement clinically of patient for there being 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 it is widely used to clinic, 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 is fairly close in its structure of anatomical structure terms of mechanics and normal human's structure, its wearability, neural autonomous perceptibilities etc. are all higher, bone tissue also can be made to absorb reduce to minimum, these all have and the functional rehabilitation activity after operation in patients are had positive role, its good pain improvement rate makes the quality of life of patient be greatly improved, range of motion also greatly improves, for improving patient's long-term prognosis, there is positive role。
Although experienced by improvement bigger 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 is owing to adopting integrated fixed structure, thus perfect cannot adapt to above-mentioned individual variation。And during current clinical up hip replacement, the angle of inserting of artificial hip prosthesis also relies primarily on experience and the sensation of 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 having some rare but the problem of objective reality, as inserted the fracture of prosthese central stabilizer support, waist muscle expands。Therefore urgently research and development one collodiaphyseal angle and the adjustable artificial hip prosthesis of top rake。
Utility model content
The present invention provides a kind of stepwise adjustable joint formula artificial hip prosthesis, with the drawback overcoming prior art to exist。The object of the invention is accomplished by:
This stepwise adjustable joint formula artificial hip prosthesis includes a pluggable handle body in femoral bone cavitas medullaris, the side of handle body extends above, 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, between one end of described elongated end and described spheroid, strand even or is connected, and 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 even, slot is coated with and fastens 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: owing to handle body and handle body are changed into engagement type grafting adjustable structure by original integral type handle body, make handle can realize sagittal plain in this junction point to rotate, again owing to linking structure for the strand of slotting falcon and slot between one end of elongated end and spheroid, namely the connection between neck of femur prosthese and femoral head prosthesis is twist-style attachment structure, simultaneously because the hinge structure between handle body elongated end and handle body, make elongated end and neck of femur realize Coronal in this strand even point to rotate, 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, the different femur patient of convenient realization installs the adjustment of collodiaphyseal angle and top rake during hip prosthesis, can greatly improve and insert, due to prosthese, prosthetic loosening and the secondary fracture that angle is brought, osteonecrosis, prosthese central stabilizer support ruptures, waist muscle such as expands at the peculiar defect of hip replacement, post-operative complication can be reduced further, hip replacement can be made to obtain anatomical reduction and firmly interior fixing 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 prominent facilitation。

Detailed description of the invention
Embodiment 1: as shown in Figure 1, this stepwise adjustable saves formula artificial hip prosthesis, and it includes a pluggable handle body 1 in femoral bone cavitas medullaris, the side of handle body 1 extends above, between the axis of elongated end 6 and the axis of handle body 1, angle is 110 °～140 °, the upper end of elongated end 6 connects a spheroid 4 matched with acetabular bone, handle body 1 is integral type structure, between the upper end of elongated end 6 and spheroid 4, strand is even, namely spheroid 4 lower end is a slotting falcon structure, the upper end of elongated end 6 is a slot matched with slotting falcon 3, insert strand between falcon 3 and slot to connect, slot is coated with fastening bolt, fastening screw bolt passes slot and slotting falcon 3, it is hinged between the lower end of elongated end 6 and handle body 1。Imaging data according to patient, top rake and collodiaphyseal angle can be carried out just successive step in sagittal plain and Coronal by the present embodiment respectively, after after femoral head excision, routine inserts the present embodiment, above-mentioned two jiaos are suitably adjusted again, then the bolt 2 fastened between bolt and elongated end 6 and handle body 1 on hinge point on locking slot according to situation in art。
