Description
Technical field
This utility model relates to orthopaedics medical instruments field, specifically a kind of biotype hip joint.
Background technology
Artificial hip joint replacing operation has become a kind of relatively common surgical operation in medical circle at present, but remains an everyway in the problem constantly explored as the implant artificial hip joint femoral shaft stability how remained in femoral bone cavitas medullaris of femur.In recent years along with the progress of industrial technology constantly has novel artificial hip joint to occur.At present, mainly contain biotype hip joint and bone-cement type hip joint, although bone-cement type hip joint is longer than the service time of biotype hip joint for service time, but need regularly to overhaul prosthese, and easily because bone cement can produce the damage of heat to osseous tissue and easily form wear particle, occur the complication such as fatigue aging; And the biotype operation on hip joint time is short, operation safety is high, operation wound is little, surgery cost is low, and bad reaction can not be produced because injecting bone cement, avoid postoperative reparation and change the trouble brought, reduce and again take out hip joint and damage to sclerotin.Therefore, biotype hip joint becomes the first-selection of artificial hip joint replacing operation, but still needs further improvement in its stability.
Summary of the invention
Problem to be solved in the utility model is: overcome the deficiencies in the prior art, provides one to be convenient to implanted femur pulp cavity, stable after implanting, effective anti-rotation, prevents from occurring between articular prosthesis and sclerotin to loosen, has the biotype hip joint of induction bone cell growth function.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of biotype hip joint, comprise acetabular component, bulb, neck of femur and articular prosthesis, described bulb is positioned at acetabular component, one end connecting ball head of described neck of femur, the other end of described neck of femur connects the near-end of articular prosthesis, the far-end of described articular prosthesis is for inserting in femoral bone cavitas medullaris, the cross section of the near-end of described articular prosthesis is ellipsoidal structure, the near-end of described articular prosthesis is hollow-core construction, the far-end of described articular prosthesis is laminated structure, the far-end of described articular prosthesis has strip hole, the far-end of described articular prosthesis is acicular texture.
Further, the near-end of described articular prosthesis is provided with latticed projection.
Further, described latticed projection is diamond structure.
Further, the strip hole on the far-end of described articular prosthesis is three.
Further, the edge of the far-end of described articular prosthesis is provided with flank.
Further, described articular prosthesis is joint handle, lengthens joint handle or Combined type joint handle.
Further, the material of described acetabular component is high hinge ultra-high molecular weight polyethylene height hinge ultra-high molecular weight polyethylene.
Further, the material of described bulb is CoCrMo alloy or pottery.
Further, the material of described joint handle is Ti-6Al-4V or Ti-6Al-7Nb; The material of described lengthening joint handle is Ti-6Al-4V or Ti-6Al-7Nb; The material of described Combined type joint handle is Ti-6Al-4V or Ti-6Al-7Nb.
The advantage that this utility model has and good effect are:
(1) this utility model biotype operation on hip joint time is short, operation safety is high, operation wound is little, surgery cost is low, and bad reaction can not be produced because injecting bone cement, avoid postoperative reparation and change the trouble brought, reduce and again take out hip joint and damage to sclerotin.
(2) cross section of the near-end of articular prosthesis of the present utility model is ellipsoidal structure, the far-end of articular prosthesis is laminated structure, the far-end of articular prosthesis has strip hole, the far-end of articular prosthesis is acicular texture, is convenient to implant into body femoral bone cavitas medullaris, stable after implanting, the near-end of articular prosthesis becomes different cross section structure with remote design, effective anti-rotation, prevents from occurring between articular prosthesis and sclerotin to loosen, and has induction bone cell growth function.
