Abstract
A rotation-resistant artificial femoral handle with a front inclination after its operation is disclosed. Its assembling process includes inserting the artificial femoral handle in the trochanter, and fixing by screw to make the toothed end of handle be engaged with the toothed end of trochanter.
Description
Affiliated technical field
The present invention relates to a kind of about the artificial hip joint femoral shaft prosthese, especially after considering hip bone tumor patient implantable bone tumorous type artificial hip prosthesis, be transformed to from sitting posture that prosthese the stance process need bear a quite big torsion and the anti-rotating type femoral bone end prosthesis that designs.
Background technology
At present, known artificial hip joint femoral shaft prosthese at the hip bone tumor is to be assembled by femoral stem tuberosity, femoral stem body, holding screw nail.The femoral stem body cone is inserted femoral stem tuberosity taper hole.From horizontal plane, femoral stem tuberosity axis and condyle of femur transverse axis form 10 °～15 ° of top rakes.But much the design of the femoral stem of this type of purposes is not considered the patient in use, how to keep 10 °～15 ° of this top rakes effectively.Cause patient's range of activity limited easily, cause operative failure.
Summary of the invention
In order to overcome the existing deficiency that can not effectively keep the top rake of postoperative, the invention provides a kind of anti-rotating type femoral bone end, this anti-rotating type femoral bone end can not only can be seen forward leaning angle in operation, and can guarantee the variation that this angle does not take place after surgery.
Embodiment
The technical solution adopted for the present invention to solve the technical problems is: increase by a circle tooth in femoral stem tuberosity and femoral stem contact level, prevent rotation.Do not free variation to guarantee this top rake.
The invention has the beneficial effects as follows, can in art, regulate top rake arbitrarily, and guarantee this angle of locking to correct position, simple in structure, reliable.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is building block principle figure of the present invention.
Fig. 2 is a femoral stem body sketch map of the present invention.
Fig. 3 is a femoral stem tuberosity sketch map of the present invention.
Fig. 4 is alternative some kinds of flute profile sketch maps.
The specific embodiment
Below in conjunction with accompanying drawing specific embodiments of the invention are described in further details.
As Fig. 1, Fig. 2, shown in Figure 3, the anti-anti-rotating type femoral bone end prosthesis of this utility model is made up of femoral stem tuberosity (1), femoral stem body (3).As Fig. 2, shown in Figure 3.Femoral stem tuberosity (1) is a tobacco pipe shape, its internal taper hole.Femoral stem body (3) is middle thick two ends form differences, and an end is a taper pin, and the other end is straight shape bar.The taper pin of femoral stem body is inserted the taper hole of femoral stem tuberosity, tighten with trip bolt.When trip bolt is lifted to the femoral stem body apart from femoral stem tuberosity profile of tooth bottom surface 1mm, adjust 10 °～15 ° of forward leaning angles after, continue the locking trip bolt, mesh fully up to the profile of tooth of femoral stem body (3) and the profile of tooth of femoral stem tuberosity (1).Make its firm stable more.
As Fig. 4, anti-rotating type femoral bone end prosthesis of the present invention is made up of femoral stem tuberosity (1), femoral stem body (3).Wherein the profile of tooth of femoral stem tuberosity (1), femoral stem body (3) can be a triangle, trapezoidal, rectangle, arc or their various combining forms.Guarantee its firm stable more.
Claims (2)
1, a kind of anti-rotating type femoral bone end prosthesis is characterized in that this anti-rotating type femoral bone end prosthesis is by femoral stem tuberosity 1, screw 2, and femoral stem body 3 is formed.When femoral stem body end face and femoral stem tuberosity bottom surface differed 3mm, the femoral stem body entered in the tooth of femoral stem tuberosity with screw fixings.
2, anti-rotating type femoral bone end prosthesis according to claim 1 is characterized in that: the profile of tooth of femoral stem body 3 and femoral stem tuberosity 1 must and can effectively mesh at unified axis.
