Abstract
The invention provides an anti-rotation anti-subsidence hip joint pseudo-stem. A plurality of horizontal grooves or ribs which are parallel are arranged at the proximal end of the pseudo-stem. Four sides of the section of the distal end of the pseudo-stem are arced. Front inclination angle of the pseudo-stem is 128-131 DEG. Intersections of the four sides of the section of the distal end are arced. The grooves or ribs on the anti-rotation anti-subsidence hip joint pseudo-stem can prevent subsidence. The section of the distal end of the pseudo-stem reduces shear action, and the quadrilateral section can prevent rotation.
Description
Technical field
The present invention relates to the false handle of a kind of anti-rotation sinking hip joint.
Technical background
The false handle of hip joint surface generally has longitudinal fluting in the prior art, and the effect of this groove is simultaneously sheared for reducing, in order to avoid increase bone cement to the adhewsive action of false handle.The present invention relates to the false handle of a kind of anti-rotation sinking hip joint.
Summary of the invention
For solving above technical problem, technical scheme provided by the invention is as follows: the near-end of false handle has several horizontal grooves or fin, and each groove or fin are parallel; Four limits in described prosthese far-end cross section are arc line shaped.
Further, the top rake of described false handle is 128 °-131 °.
Further, the intersection on four limits, described far-end cross section is arc.
The false handle of this anti-rotation sinking hip joint that the present invention relates to, being designed with to be beneficial to of groove and fin prevent from, the design of prosthese far-end cross sectional shape, and one side reduces shear action, and its tetragonal design of another side can be played the effect of rotating of preventing.
Description of drawings
Fig. 1 is the false handle front view of the anti-rotation sinking hip joint of the present invention;
Fig. 2 is that the far-end section A-A is to cutaway view;
Labelling is as follows among the figure: the 1-neck of femur; The 2-fin; The 3-near-end; The 4-far-end.
The specific embodiment
Shown in Fig. 1-2, the near-end 3 of false handle has several horizontal fins 2, and each fin 2 is parallel; As shown in Figure 2, four limits in prosthese far-end 4 cross sections are arc line shaped.
The top rake a of neck of femur 1 is 128 °-131 °.
The intersection on four limits, far-end 4 cross sections is arc.
The false handle of this anti-rotation sinking hip joint of the present invention's design, simple in structure, easily manufactured, need not special processing, can do blasting treatment on the surface of false handle, increase the adhesive force of bone cement.The material of prosthese can rotate, titanium alloy and vitallium.Its less top rake makes the range of activity of implementing the relative health of postoperative people's lower limb less, therefore should be more suitable in older people by the vacation handle.
Claims (3)
1. the false handle of anti-rotation sinking hip joint comprises near-end and far-end, it is characterized in that, the near-end of described false handle has several horizontal grooves or projection, and each groove or projection are parallel; Four limits in described prosthese far-end cross section are arc line shaped.
2. the false handle of anti-rotation sinking hip joint according to claim 1 is characterized in that, the top rake of described false handle is 128 °-131 °.
3. the false handle of anti-rotation sinking hip joint according to claim 1 is characterized in that, the intersection on four limits, described far-end cross section is arc.
