The utility model provides an acetabular cup false body has solved among the prior art that the fixed effect of acetabular cup false body is poor, unsatisfactory technical problem is grown into to the sclerotin.
Description
Technical field
This utility model relates to hip implant, is specifically related to a kind of acetabular cup prosthesis.
Background technology
Hip joint is the joint being connected between the Thigh bone of human body and the hipbone of pelvis, is that the mankind are in the joint sitting or play most important functions immediately.When hip joint is impaired due to factors such as the disease reason of tuberculosis and so on and wounds, in order to make it fully recover, by artificial hip joint replacing excision focus, removing pain, recovering the activity in joint and original function.Hip prosthesis comprises acetabular component and femoral prosthesis, and acetabular component inside is provided with liner, and acetabular component is fixed in human body hipbone physiology acetabular bone, and femoral prosthesis is fixed on human femur under loading upper end by femoral stem.In existing hip prosthesis, acetabular component usually in dome-type, also referred to as acetabular cup, metal ball-head corresponding with model in Replacement of Hip Joint with the use of, for replacing the physiology acetabular bone of pelvis.Acetabular cup is divided into anti-dislocation and standard type two kinds.Usual acetabular cup adopts loose structure, and thermal spraying on surface lays metal or bioceramic rough coatings, thus is conducive to growing into of sclerotin, is finally firmly fixed in acetabular bone, but this mode sclerotin is grown into, the phase needs the longer time.Owing to acetabular component spherical outside surface lacking necessary fixture, before being combined with human body bone by loose structure, must first allow acetabular component be fixed fast and effectively in human body acetabular bone, this is the problem that must solve with the rehabilitation stage in corrective surgery.Existing fixed form is normally adopted and is screwed, and the spheroid of acetabular component arranges several open-works, and use as the fixing hole wearing screw, quantity is generally 3.But in conjunction with undesirable, easily there is loosening gap in the rehabilitation stage, cause solid failure in screw and human body bone, the sclerotin in later stage is grown into and can not well be realized, operative effect is undesirable is on the one hand, sometimes also has to patient's second operation, brings follow-up injury and misery to patient.
Utility model content
The purpose of this utility model is to provide a kind of acetabular cup prosthesis, solves that acetabular cup prosthesis fixed effect in prior art prior art is poor, sclerotin grows into undesirable technical problem.
This utility model realizes in the following manner: a kind of acetabular cup prosthesis, comprise the joint face that hemispheric bulb, bottom in inclined-plane and described bulb are crossing with bottom, top, described bulb is provided with projection, bulb outer surface is evenly placed with groove around bulb, the cross section of described groove is parallel to each other, bulb outer surface is provided with recess perpendicular to described groove, and described recess extends to joint face from top, bulb, is provided with fin near in the groove of joint face.
Preferably, the degree of depth of described groove is greater than the height of described fin.
Preferably, the angle that described groove extends to form in bulb is 50 °.
Preferably, it is 75 ° that described bottom extends to the bottom surface of bottom the maximum angle formed with joint face from joint face, and minimum angle is 10 °.
Preferably, described recess is 6.
A kind of hip prosthesis that this utility model provides, the projection arranged by top, bulb and hip prosthesis is fixed in human body acetabular bone near the fin arranged in the groove of joint face, grow with human body bone, the groove that bulb outer surface is evenly arranged around bulb and being combined with human body bone perpendicular to the recess on described groove, both increased the primary stability after acetabular cup prosthesis implantation, and be beneficial to again sclerotin and prosthese grown into recklessly at acetabular bone, combines.

Detailed description of the invention
Hereinafter also describe this utility model in detail with reference to accompanying drawing in conjunction with the embodiments.It should be noted that, when not conflicting, the embodiment in this utility model and the feature in embodiment can combine mutually.
Embodiment 1
As Figure 1-4, present embodiments provide a kind of acetabular cup prosthesis, comprise the joint face 3 that hemispheric bulb 1, bottom 2 in inclined-plane and described bulb 1 are crossing with bottom 2, top, described bulb 1 is provided with protruding 4, bulb 1 outer surface is evenly placed with groove 5 around bulb 1, and the cross section of described groove 5 is parallel to each other, and bulb 1 outer surface is provided with recess 6 perpendicular to described groove 5, described recess 6 extends to joint face 3 from top, bulb 1, is provided with fin 7 near in the groove 5 of joint face 3.During the present embodiment Hu acetabular cup prosthesis implantation sclerotin, the resistance of sclerotin feedback is little, and sclerotin loss is less, protruding 4 increase with the setting of fin 7 stability that acetabular cup prosthesis implants the initial stage, the setting of groove 5 and recess 6 is beneficial to the combination of sclerotin and hip prosthesis, bottom 2 structures are beneficial to and the coordinating of respective femur handle, and are beneficial to human body later stage functional rehabilitation and physical rehabilitation.
Wherein, the degree of depth of described groove 5 is greater than the height of described fin 7.The initial stage being beneficial to acetabular cup prosthesis implant into body acetabular bone is fixed.
Wherein, the angle that described groove extends to form in bulb 1 is 50 °, angle P as shown in Figure 1.Be beneficial to sclerotin growing on acetabular cup prosthesis.
Wherein, it is 75 ° that described bottom 2 extends to the bottom surface of bottom 1 maximum angle formed with joint face 3 from joint face 3, and minimum angle is 10 °, respectively angle M and N as shown in Figure 1.
Wherein, described recess 6 is 6, and the radial centre lines extended line angle not having two recesses is 60 °.Be beneficial to sclerotin growing on acetabular cup prosthesis, make the stability at later stage of hip prosthesis better.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail this utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that: it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of this utility model.
