Description
Technical field
The invention belongs to Design for Medical Device technical field, more particularly, to a kind of minimally invasive hip prosthesis system.
Background technology
Total hip replacement has been widely used for the treatment of the diseases such as Osteoarthritis, head necrosis at present, in
Femoral stem used in the first replacement of total hip of adolescent patients has higher requirement.In actual clinical replacement of total hip
In can be potentially encountered following case：Patient is younger, more demanding to performing the operation, and activity is larger, and particularly femoral bone cavitas medullaris is relatively narrow,
Judge according to Dorr pulp cavitys opening index, belong to femur anatomic form or some trouble of the champagne cup type (Dorr A) of CFI ＞ 4.7
Person's stature is shorter, and weight is lighter, and femoral bone cavitas medullaris is tiny, belongs to plain edition (DorrB) patient of 4.7 ＞ CFI ＞ 3.0, Huan Zhepi
Matter morphological indices (MCI) scoring 0~4/, bone amount is preferable.This case can sacrifice excessive as selected long handle prosthese
Bone tissue or even since Distal femoral metaphysis pulp cavity is narrower (such as patient of hip dysplasia (DDH)), prosthese occur can not
Distal end pulp cavity is squeezed into, so that femur is caused to cleave because strongly squeezing into.
Invention content
The problem to be solved in the present invention is to provide a kind of more bone amount of reservation, has wide range of applications, can be with skeleton phase
Fusion is stablized convenient for mini-invasive incision and is installed, while can improve the minimally invasive hip prosthesis system of prosthesis system mobility.
In order to solve the above technical problems, the technical solution adopted by the present invention is：A kind of minimally invasive hip prosthesis system, including
Femur short handle prosthese, acetabular cup, liner and femoral head prosthesis, the femur short handle prosthese include head, shank and connect the head
Portion and the neck of shank；The femoral head prosthesis is set to femur short handle prosthese top, matches with femur short handle prosthese head；
The acetabular cup is 2/5 spherical acetabular bone structure, which is internally provided with matched liner；The liner is set to
On the outside of femoral head prosthesis, match with femoral head prosthesis；Double coatings of microcellular structure are coated on the outside of the femur short handle prosthese
Or the metal bone trabecula of complex porous structure, double coatings include the inner coating and cladding for being combined with human body bone trabecula
External coating on the outside of inner coating for being blended with skeleton；The femur short handle prosthese shank is provided with boss.
The inner coating material is pure titanium titanium valve；The external coating material is hydroxyapatite.
The metal bone trabecula material is titanium alloy or pure titanium.
The boss, which is 200~300 microns, prevents sinking ladder, and have the anti-spin slot of exhaust in remote design.
The pure titanium titanium valve inner coating thickness is 700 microns；The hydroxyapatite external coating thickness is 100 microns.
The shank cross section is rectangle.
Due to the adoption of the above technical scheme, (1) type femoral bone end prosthesis of the present invention is short handle, and short handle prosthese is (alternatively referred to as minimally invasive
Rectangle prosthese) design retain more bone amount, this provides wider selection, and since short handle is proximal end to perform the operation later
Fixed design, without the concern for middle distal end, the dissection of femoral shaft atypia or the additional fixed patient of needs may be selected using short
Handle prosthese；(2) in order to which short handle prosthese is coordinated to realize minimally invasive total hip replacement, 2/5 spherical acetabular bone is devised, different from existing
Typical acetabular prosthese is realized and stablizes installation convenient for mini-invasive incision, while can improve the mobility of prosthesis system；(3) femur
Double coatings of microcellular structure or the metal bone trabecula of complex porous structure, the pure titanium titanium of double coatings are coated on the outside of short handle prosthese
For being combined with human body bone trabecula, hydroxyapatite external coating is used to blend with skeleton powder inner coating；Metal bone trabecula
Porous structure is conducive to Bone Ingrowth；(4) boss, which is 200~300 microns, prevents sinking ladder, and have exhaust in remote design
Anti- spin slot；For boss therein with sinking effect is prevented, being vented anti-spin slot has the function of anti-rotation, decompression exhaust.
The beneficial effects of the invention are as follows：With more bone amount are retained, have wide range of applications, can be blended with skeleton,
The advantages of stablizing convenient for mini-invasive incision and install, while prosthesis system mobility can be improved.
