The novel double-action hip joint prosthesis mainly comprises an acetabular cup, a polythylene liner, a locking ring and a femoral head and is characterized in that a circle of groove is formed at the bottom of the polythylene liner; firstly, the femoral head is put into a ball socket of the polythylene liner, and then the locking ring is put into the groove of the polythylene liner and is arranged at the upper end of the femoral head; and the polythylene liner is externally arranged in the acetabular cup. The novel double-action hip joint prosthesis has the beneficial effects of being capable of solving the risk problem of dislocation of the femoral head in polythylene liner, not only being convenient to implant during operation, but also avoiding the dislocation risk of the femoral head after operation; and due to adoption of the novel double-action hip joint prosthesis, relatively good initial fixation and good long-term fixation of the femoral head in the polythylene liner are achieved, and the femoral head is convenient to install.
Description
Technical field
The present invention relates to a kind of osteoarticular prosthese of similar human body, specially a kind of novel double-movable hip prosthesises.
Background technology
Artificial hip joint replacing refers to similar with one kind that the metal material of satisfactory mechanical property is made with biocompatibility
The osteoarticular prosthese of human body, articular surface prosthetic replacement being destroyed by i or I using operation method, its purpose
It is removal of lesions, removes pain, recover movable and original function in joint.Prosthetic replacement has joint motion preferably,
Can early stage Go to ground activity, reduce elderly patients' long-term bed complication the advantages of, in European and American developed countries, prosthetic replacement
Operation has been one of modal operation.The development of China's hip replacement in recent years is also very good rapid.In recent years, in Europe
Hair caring reaches market, and double dynamic full hip-joint products are gradually employed, and compares with commonly full hip, has degree of stability high（It is difficult to dislocate）And work
The feature that dynamic scope increases.
Common full hip-joint product, artificial hip joint product is typically made up of four parts.Femoral stem, usually metal material
Material；Femoral head, usually metal or ceramic material；Acetabular bone liner, usually ultra-high molecular weight polyethylene or ceramic material；
Acetabular cup, usually metal material.
Double dynamic full hip-joint products, metal cup is first implanted to acetabular fossa, and femoral head is initially charged with polyethylene liner, afterwards with stock
Bone handle links.Resetted again.So there are two active interface：Femoral head and polyethylene liner, and polyethylene liner and hip
Mortar cup.Two active interface can provide bigger mobility for hip joint, simultaneously because the diameter of polyethylene liner is than common
The femoral head diameter of full hip is big, so stability is more preferable.
With the double dynamic full hip-joint product of metal inner lining, metal cup is first implanted to acetabular fossa, and metal inner lining is encased in metal
In cup, close-fitting between the two, no relative motion；Femoral head is initially charged with polyethylene liner, links with femoral stem afterwards.Carry out multiple again
Position.So there are two active interface：Femoral head and polyethylene liner, and polyethylene liner and acetabular cup.Two active interface
Bigger mobility can be provided for hip joint, simultaneously because the diameter of polyethylene liner is than the femoral head diameter of commonly full hip
Greatly, so stability is more preferable.
But above two scheme does not all solve a problem it is simply that the wind dislocated from polyethylene liner of femoral head
Danger.Generally femoral head passes through special apparatus, in press-in polyethylene liner, by dimensional fits between the two, so that
Femoral head is not easy dislocation from polyethylene liner.But it is as the increase of joint service life, equally can occur between the two
Dislocation, thus leading to operation on hip joint failure, needs to do revision procedure.
Content of the invention
It is an object of the invention to provide a kind of novel double-movable hip prosthesises, this novel double-movable hip prosthesises energy transfer of share
Bone obtains preferably initially fixing and good long-term fixation in polyethylene liner, and can conveniently install.
The technical solution used in the present invention is as follows：A kind of novel double-movable hip prosthesises, mainly include acetabular cup, polyethylene
Liner, locking ring, femoral head；It is characterized in that：In the inside of polyethylene liner, open a circle groove, first femoral head has been put into
In the ball-and-socket of polyethylene liner, then locking ring is placed in the groove of polyethylene liner, locking ring is arranged on femoral head upper end；
Polyethylene liner external in acetabular cup.
In double dynamic hip prosthesises of the present invention, also there is metal inner lining, set between polyethylene liner and acetabular cup
There is one piece of metal inner lining；Its effect is：With the double dynamic full hip-joint product of metal inner lining, metal cup is first implanted to acetabular fossa, gold
Belong to liner to be encased in metal cup, close-fitting between the two, no relative motion.
Double dynamic hip prosthesises do not have metal inner lining, and described acetabular cup is made up of two parts, are microcellular structure part and reality
Core structure part, the microcellular structure part of acetabular cup and the acetabular fossa directly contact of human body；Described acetabular cup is hemispherical dome structure,
Its exterior semi-spherical surface is microcellular structure part, and inner surface is solid construction part.
Double dynamic hip prosthesises have metal inner lining, and described acetabular cup is made up of two parts, are microcellular structure part and solid
Structure division, the microcellular structure part of acetabular cup and the acetabular fossa directly contact of human body；Described acetabular cup is hemispherical dome structure, its
Exterior semi-spherical surface is microcellular structure part, and inner surface is solid construction part, in hemispherical dome structure surface solid construction part
Place is provided with one week meniscate groove；Need to design 6-10 through hole around meniscate groove or according to installation；Described
Through hole and meniscate groove need to design according to installation.
Double dynamic hip prosthesises have metal inner lining, on described hemispherical dome structure or be provided with 1 or be provided with three to ten two lead to
Hole.
Polyethylene liner of the present invention is hemispherical dome structure, in hemispherical dome structure interior location just corresponding placement femur
Head, is provided with a groove in hemispherical dome structure upper end, and size is just equal in magnitude with locking ring.
Locking ring material of the present invention be polythene material, locking ring be open annular, at open annular about two
Individual corner is provided with 2 grooves, and Main Function is that the blessing for the instrument of accommodating uses.
The method that locking ring of the present invention is fit into polyethylene liner is：Tighten up locking with the blessing instrument making
Ring, loads in the groove of polyethylene liner；Decontrol locking ring, due to the elasticity of polythene material, locking ring is placed in polyethylene
In the groove of lining, the opening of locking ring is less than femoral head simultaneously, and femoral head also would not be deviate from from polyethylene liner.
Blessing instrument of the present invention similar to shears, is exclusively used in opening and tightening up use of locking ring, its architectural feature
It is that two blessing bars pass through middle bearing pin connection, wherein one end of two blessing bars is arranged respectively to handle, the other end two
Accommodate the corresponding bending of bar.
Beneficial effects of the present invention are：Can solve the problem that the risk problem that femoral head is dislocated from polyethylene liner, both facilitated
Implant in operation, turn avoid the risk of Post operation femoral head dislocation, this novel double-movable hip prosthesis can allow femoral head poly-
Obtain preferably initially fixing and good long-term fixation in ethylene liner, and can conveniently install.
