It should be noted that, when not conflicting, the embodiment in the application and the feature in embodiment can combine mutually.Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
As shown in Fig. 1 to 2, the invention provides a kind of acetabular component, comprise acetabular bone main body 10 and Anti-slip cover 30, Anti-slip cover 30 is connected with acetabular bone main body 10.
In the present embodiment, acetabular bone main body 10 is arranged Anti-slip cover 30, add the stability after hip joint combination and the activity sensitivity degree of hip joint, to solve acetabular bone main body easily and the problem that comes off of femoral stem.
In the present embodiment, acetabular bone main body 10 and the link of femoral stem 20 are provided with the Anti-slip cover 30 preventing femoral stem 20 and acetabular bone main body 10 from coming off, Anti-slip cover 30 is connected to acetabular bone main body 10 and femoral stem 20, and acetabular bone main body 10 and femoral stem 20 all cannot be dislocated from Anti-slip cover 30.Acetabular bone main body 10 arranges Anti-slip cover 30, plays and prevent bulb 40 and acetabular bone main body 10 from dislocating, add the activity sensitivity degree of the stability after hip joint combination and hip joint.In the present embodiment, Anti-slip cover 30 is connected with the outer surface of acetabular bone main body 10.In order to make the acetabular component after combination have more stability simultaneously also for assembling is easier to operation, Anti-slip cover 30 is arranged on the outer surface of acetabular bone main body 10.
And then ground, the outer surface phase clamping of Anti-slip cover 30 and acetabular bone main body 10.In order to increase Anti-slip cover 30 and the bonding strength on acetabular bone main body 10 surface, Anti-slip cover 30 is connected to the outer surface of acetabular bone main body 10.
In the present embodiment, Anti-slip cover 30 has the first locking hole 31 and the second locking hole 32 be oppositely arranged, acetabular bone main body 10 and the first locking hole 31 phase clamping, the bulb 40 of femoral stem 20 is sheathed in Anti-slip cover 30 and makes bulb 40 rotatable relative to the inner surface of acetabular bone main body 10, the diameter of bulb 40 is greater than the diameter of the second locking hole 32, and bulb 40 coordinates with the second locking hole 32 with the connecting portion of the link 22 of femoral stem 20.。Femoral stem 20 comprises free end 21 and link 22, bulb 40 is arranged at link 22, bulb 40 is fixedly connected with link 22 or is wholely set, and Anti-slip cover 30 connects acetabular bone main body 10 and link 22, makes bulb 40 rotatable relative to the inner surface of acetabular bone main body 10.Offer in the both sides of Anti-slip cover 30 first locking hole 31 and the second locking hole 32, first locking hole 31 for the clamping of acetabular bone main body 10 phase.Second locking hole 32 is for fastening bulb 40, and it is inner that bulb 40 is sheathed on Anti-slip cover 30, and the diameter of bulb 40 is greater than the diameter of the second locking hole 32, and bulb 40 coordinates with the second locking hole 32 with the connecting portion of link 22.Such setting prevents the acetabular bone main body 10 in the acetabular component after combining from dislocating with bulb 40 effectively.
In the present embodiment, the outer surface of acetabular bone main body 10 has the edge card connecting draw-in groove 11, first locking hole 31 and is located at and connects in draw-in groove 11.In order to prevent acetabular bone main body 10 and Anti-slip cover 30 from coming off, the outer surface of acetabular bone main body 10 is provided with the connection draw-in groove 11 for the edge phase clamping with the first locking hole 31, and the edge card of the first locking hole 31 is located at and connects in draw-in groove 11 and clamp.
In the present embodiment, Anti-slip cover 30 has interconnective first anti-drop cover 33 and the second anti-drop cover 34, first locking hole 31 is opened on the first anti-drop cover 33, and the second locking hole 32 is opened on the second anti-drop cover 34, the second anti-drop cover 34 offers at least one permeability hole 35.Anti-slip cover 30 can be arranged to integral type, also can be arranged to split type.Enter into hip prosthesis assembly for the ease of human synovial liquid, to ensure to realize lubrication friction between hip prosthesis articular surface, the second anti-drop cover 34 offers at least one permeability hole 35.
In the present embodiment, under the prerequisite ensureing Anti-slip cover 30 intensity, offer multiple permeability hole 35, and multiple permeability hole 35 is uniform along the second locking hole 32 circumference.The second locking hole 32 circumference arrange all with distribution permeability hole 35, can realize to make the hip prosthesis after combination lubricating to greatest extent, thus effectively decrease the friction between hip prosthesis, add the service life of hip prosthesis.
In the present embodiment, the first locking hole 31 and the second locking hole 32 are coaxially arranged.The first locking hole 31 be connected with hip acetabular bone main body 10 and the second locking hole 32 of being connected with femoral stem link 22 are coaxially arranged, stability and the precision of hip prosthesis can be strengthened.
In the present embodiment, Anti-slip cover 30 is elasticity Anti-slip cover.Pull because the hip prosthesis implanting rear human body can produce vibration thus cause between hip acetabular bone main body 10 and bulb 40 whole hip prosthesis when physical activity, therefore be arranged to the Anti-slip cover 30 be arranged between hip acetabular bone main body 10 and bulb 40 to have the Anti-slip cover of spring function, effectively avoid and cause bulb 40 because pullling between hip acetabular bone main body 10 and bulb 40 or hip acetabular bone main body 10 departs from Anti-slip cover 30.
Preferably, elasticity Anti-slip cover is made up of medical silica-gel.The spring function of medical silica-gel Anti-slip cover 30 adds the flexibility ratio of hip prosthesis.
In the present embodiment, Anti-slip cover 30 is in elliposoidal.Anti-slip cover 30 is arranged to elliposoidal, and on the minor axis sphere of elliposoidal Anti-slip cover 30, is provided with the first locking hole 31 be connected with acetabular bone main body 10, the minor axis sphere of the first locking hole 31 offside is provided with the second locking hole 32 with the clamping of bulb 40 phase.Because of in the Anti-slip cover 30 of elliposoidal, area on minor axis sphere is greater than the area of major axis sphere, be conducive to offering difform connecting hole, and because the distance of two minor axis spheres is at a distance of recently, make the acetabular bone main body 10 be arranged in Anti-slip cover 30 can realize effectively contacting and forming frictional interface with acetabular bone main body 10 inner surface with bulb 40.In the present embodiment, after the distance between acetabular bone main body and bulb is reasonably set, also can be arranged on other positions on the Anti-slip cover 30 in spheroid-like.
As can be seen from the above description, the above embodiments of the present invention achieve following technique effect:
1, acetabular bone main body 10 and the link of femoral stem 20 are provided with the Anti-slip cover 30 preventing femoral stem 20 and acetabular bone main body 10 from coming off, Anti-slip cover 30 is connected to acetabular bone main body 10 and femoral stem 20, and acetabular bone main body 10 and femoral stem 20 all cannot be dislocated from Anti-slip cover 30.Acetabular bone main body 10 arranges Anti-slip cover 30, plays and prevent bulb 40 and acetabular bone main body 10 from dislocating, add the activity sensitivity degree of the stability after hip joint combination and hip joint.
2, effectively decrease the probability of friction between hip prosthesis and dislocation of hip joint, add the service life of hip prosthesis.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
