Description
Technical field
The utility model is related to artificial hip joint technical field, specially a kind of biological combined artificial hip of 3D printing lightweight
Articular prosthesis handle.
Background technology
With the aggravation of aging population, egeneration osteoarthritis dysfunction increases year by year, and such patient is led to
Often need to receive Replacement of Hip Joint to be treated.Replacement of Hip Joint has turned into treatment hip joint whole Terminal Disease
Mature technology, the artificial hip prosthesis clinically used at present can be divided into cement reaction type prosthese and none-cement is fixed
Type prosthese.Such as China's number of applying for a patent is 2002271916.4, a kind of artificial hip prosthesis' handle, the artificial hip prosthesis
Handle is some levels of surface top-down nano-fabrication in existing artificial hip joint stem shank body near-end and mutual equidistant balance
Zigzag fin, can prevent artificial hip joint stem in human femur under loading pulp cavity easily loosen and sink, improve artificial pass
Save the stability after handle implantation.But each is equal with femur laminating sideways during such artificial hip prosthesis' handle insertion near end of thighbone
More close, the discharge such as air, blood in femoral bone cavitas medullaris is difficult, and the pressure being easily caused in femoral bone cavitas medullaris substantially increases, greatly
The big incidence for improving fat embolism syndrome.Also once it has been proposed that being opened in the center of artificial hip prosthesis' handle in an insertion
Under through hole play a part of being vented and reduce marrow internal pressure, but say, opened in the center of prosthesis handle from the angle of biomethanics
Hole can influence the intensity of whole prosthesis handle, and manufacture craft difficulty is larger.Therefore, need one kind badly and be easy to air, blood discharge,
Femur marrow cavity pressure will not be increased, prosthesis handle intensity in the prior art is kept, and the simple artificial hip joint of manufacture craft is false
Body handle, but had not been reported at present on this kind of prosthesis handle.Such as Chinese Patent Application No. is 201510743660.3 a kind of
Artificial hip prosthesis' handle of Periprosthetic fracture is treated, belongs to orthopedic medical device technical field, is put for treating hip joint
Change postoperative Periprosthetic fracture.Its technical scheme is：Multiple fixing holes are set in the stage casing of prosthesis handle and distal end, fixing hole is from vacation
Run through prosthesis handle to inner side on the outside of body handle, the lengthwise centers line of fixing hole is vertical with the length direction of prosthesis handle, multiple fixing holes
It is parallel to each other.The present invention is reserved with fixing hole on prosthesis handle, in Periprosthetic fracture after treating hip replacement, Ke Yidan
Pure use fixation, it is not necessary to which wirerope cerclage is fixed.Interal fixation screw can be through reserved fixing hole and femur
Inside and outside two layers of cortex is fastened around fracture, reaches good fixed effect, its mechanical stability is greatly increased, and influence is whole
The intensity of prosthesis handle, and manufacture craft difficulty is larger, the problem of weight is larger, in view of it is mentioned above the problem of, this practicality is new
Type designs a kind of biological combined artificial hip stem of 3D printing lightweight, the problem of to solve mentioned above.
The content of the invention
The purpose of this utility model is to provide a kind of 3D printing lightweight biological combined artificial hip stem, to solve
The intensity that is proposed in certainly above-mentioned background technology is relatively low and the problem of big weight.
To achieve the above object, the utility model provides following technical scheme：A kind of compound people of 3D printings lightweight biology
