Description
Technical field
The present invention relates to medical field, and in particular to the anti-dislocation hip prosthesis and its system of a kind of 3D printing acetabular bone liner
Make method.
Background technology
Artificial total hip arthroplasty as treat old hip joint severe osteoarthritic, caput femoris necrosis late period and
Fracture of neck of femur routine operation, its operative effect have obtained the affirmative of clinic, controlled from the earliest period hip replacement surgery sixties
Elderly patient severe osteoarthritic disease is treated, young patient recovers hip joint good function by hip replacement till now, raw
The progress of thing engineering science and materialogy undoubtedly plays very important effect, but hip replacement is concurrent there is also some
Disease, such as aseptic loosening, Periprosthetic infection and management of dislocation following total hip arthroplasty.Previously research report hip replacement
Prothesis dislocation incidence is 1%~3%, is only second to aseptic loosening, the hair of the artificial dislocation of hip joint after artificial semi-pelvis displacement technique
Raw rate is up to 8.3%, and the postoperative displacement rate of hip revision then may be up to 5%~20%, and document also reports that hip joint is put in addition
Change the probability that prothesis dislocation occurs again in postoperative first dislocation patient and be up to 55%.After Redislocation guard or revision procedure not only
Increase length of patient stay, influence postoperative function recovery, while also result in medical resource and additionally consume.Previously research is clear and definite
Point out numerous influence factors of management of dislocation following total hip arthroplasty, including patient's oneself factor, prosthetic designs and surgical technic etc..
Therefore we can prevent management of dislocation following total hip arthroplasty by improving prosthetic designs.From mechanics, the dislocation of hip joint is
Late-segmental collapse is first vertical again parallel to the movement on acetabular bone surface, is the knot for promoting and preventing two kinds of strength of dislocation from confronting with each other
Fruit, hip joint activity exceed certain limit and lesser trochanter or femoral prosthesis and the shock of acetabular bone and its surrounding soft tissue just occur,
If preventing the strength of dislocation to be not enough to stop this tendency, will dislocate.
The other stabilization of hip joint and the tension force of the containing in joint and surrounding soft tissue have relation, if joint containment relationship
Bad such as acetabular bone either femoral stem lean forward or acetabular bone abduction position is placed bad acetabular bone and the femoral head of may result in and contained
Difference, the hip joint scope of activities needed for daily routines this may result in hitting so as to dislocate.In addition soft group around hip joint
The tension force knitted is the principal element of confrontation dislocation, if the reason for patient is because of in terms of neuromuscular causes around hip joint soft group
Knit Tension Difference, then the stability of hip joint is with regard to poor, so as to cause to dislocate.In addition, conventional hip prosthesis uses acetabular bone at present
Liner minor radius designs, in order that facilitating femoral head in art to squeeze into, but this design does not include anti-dislocation mechanism, only by acetabular bone
The containment relationship and surrounding soft tissue's tension force of prosthese and femoral head enter row constraint, and this prosthetic designs can undoubtedly increase postoperative prosthese
Displacement rate.Therefore, part producer prevents the dislocation of hip joint by increasing femoral head diameter and increase acetabular bone liner flash.Machine
Principle processed is:1. femoral head is bigger, jumping out needed for dislocation occurs, and distance is bigger, and hip joint is more stable, but there is also disadvantage
End.First, increase femoral head diameter will certainly reduce acetabular bone thickness of inner lining, so as to influence the life-span of acetabular bone liner.Furthermore previously
Research finds that the diameter for increasing femoral head can increase the abrasion between acetabular bone liner and femoral head, so as to influence the life-span of prosthese.
2. acetabular bone liner is formed super radius by increase acetabular bone liner part flash, it can so increase bag of the acetabular bone liner to femoral head
Hold, but acetabular bone liner and femoral head are separately manufacturings at present, it is contemplated that femoral head is squeezed into art, and its acetabular bone liner flash is set
In respect of limit, its result is also that can only reduce dislocation to a certain degree.In summary, the anti-dislocation skill of hip replacement at present
Art effect is limited, drawback be present.
In addition, hip or near end of thighbone tumor patient hip joint surrounding soft tissue function are very poor, cause postoperative dislocation rate
Apparently higher than common hip replacement.Acetabular bone and femoral head prosthesis are split forging, and hip prosthesis is super radial design, institute
The super radial design of meaning, i.e. hip joint liner have exceeded hemispherical, certain coating are formd to femoral head, and hip joint liner is outside
The radian more than radius of extension is referred to as super radius arcuate.But on the one hand its locking mechanism locks for mechanicalness, by acetabular bone
The super radius flash of liner enters row constraint to femoral head, in order to can guarantee that inserting for femoral head in art, the super radius model of its acetabular bone liner
Limit is with, femoral head needs external force to squeeze into by force in art in addition, and this implantation mode can damage its locking mechanism, in clinical observation
The postoperative dislocation of hip joint still has generation.And the dislocation of hip joint recurrent is easily caused after first dislocation.

Product manufacture：" from below to up " accumulation mode is for realizing non-even cause material, functionally gradient device advantageously.3D printing at present
Technology can print the thing that conventional fabrication process can not manufacture, therefore we can realize completely using the technology
The acetabular bone liner for the anti-dislocation that we want is printed on femoral head.
Secure lock between acetabular bone liner and femoral head is realized by increasing acetabular bone liner flash, so as to effectively prevent
Femoral head is deviate from.This design is specially adapted to that hip joint surrounding soft tissue tension force is not good enough and seriously soft group of hip tumor post-operation
