Abstract
The utility model relates to the technical field of medicine production equipment, specifically to an artificial hip joint fixing device. The artificial hip joint fixing device comprises an artificial femoral stem and a bone wall. The artificial femoral stem consists of a head part and a body part. The artificial hip joint fixing device is provided with a connecting rod. A near-end of the connecting rod is connected with the head part of the artificial femoral stem while the far-end of the connecting rod extends outwardly and is parallel to the bone wall. The far-end of the connecting rod is fixedly connected with the body part through locking screws. The connecting rod firmly fixes the artificial femoral stem and the bone wall so that the loosening and sinking of the artificial femoral stem is prevented effectively and the service life of the artificial hip joint is prolonged greatly.
Description
Technical field
This utility model relates to medical production equipment technical field, is specifically related to a kind of artificial hip joint fixture.
Background technology
The therapeutic effect of Replacement of Hip Joint has obtained also having developed into certainly fully a kind of reliable treatment means through the clinical practice of three more than ten years.The artificial joint replacement main purpose is to alleviate arthralgia, correction deformity, recovery and improve the motor function in joint.For the bad patient of part sclerotin condition, often need use the bone-cement type artificial hip joint replacing.
The bone-cement type artificial hip joint replacing generally after femoral bone cavitas medullaris expands the pith knot bundle, injects bone cement in the pulp cavity now, inserts artificial artificial femur handle again, and artificial thigh bone then is installed again.
The problem that prior art exists is; After use after a while; Between the interface of artificial artificial femur handle and bone cement, between the interface of bone cement and femur bone wall; Can appearance become flexible, cause becoming flexible, rotate or sinking of artificial artificial femur handle, make the patient service life of pain, limping and shortening artificial hip joint occur.Especially for the artificial hip joint replacing of overhauling, it is very smooth that femoral bone cavitas medullaris is rubbed, and the frictional force at bone cement and femur marrow spinal joints wall interface reduces, and occurs the problems referred to above more easily.
Therefore, to the problem that exists in the prior art, it is particularly important to need the technology that a kind of artificial hip joint fixture is provided badly.
Summary of the invention
The purpose of this utility model is the deficiency to prior art, and a kind of artificial hip joint device of fixation is provided.
The purpose of this utility model realizes through following technical scheme:
A kind of artificial hip joint fixture is provided; Comprise artificial femur handle and bone wall; Said artificial femur handle comprises that head and the said artificial hip joint fixture of body are provided with connecting rod; Said connecting rod near-end and head link to each other, far-end extends laterally and parallel with the bone wall, and the far-end of connecting rod is fixedly connected through lock screw with body.
Wherein, said head is provided with the groove with connecting rod near-end coupling, and said body is provided with the locking nail hole with the lock screw coupling.
Wherein, said connecting rod is provided with limited bayonet, and said limited bayonet cooperates with said groove is nested.
Wherein, said limited bayonet is fixedly connected with said groove through gim peg.
Wherein, said limited bayonet is the limited bayonet of U-shaped.
Wherein, said artificial hip joint fixture is provided with guide cylinder, and said guide cylinder is arranged in said locking nail hole, and said lock screw is arranged in the said guide cylinder.
The beneficial effect of this utility model:
A kind of artificial hip joint fixture; Comprise artificial femur handle and bone wall; Said artificial femur handle comprises that head and the said artificial hip joint fixture of body are provided with connecting rod; Said connecting rod near-end and head link to each other, far-end extends laterally and parallel with the bone wall, and the far-end of connecting rod is fixedly connected through lock screw with body.
Connecting rod can effectively prevent firm fixing of artificial femur handle and bone wall that artificial femur handle is loosening, sink, and prolongs artificial hip joint service life greatly.
Description of drawings
Utilize accompanying drawing that this utility model is described further, but the embodiment in the accompanying drawing does not constitute any restriction to this utility model.

Fig. 2 is limited bayonet and the structural representation of gim peg of a kind of artificial hip joint fixture of this utility model.
Fig. 3 is the structural representation of connecting rod of a kind of artificial hip joint fixture of this utility model.
In Fig. 1, Fig. 2, Fig. 3, comprise: 1---artificial femur handle, 2---limited bayonet, 3---the bone wall, 4---lock hole, 5---lock screw, 6---guide cylinder, 7---gim peg.
The specific embodiment
Below in conjunction with embodiment this utility model is elaborated.
A kind of artificial hip joint fixture; As shown in Figure 1; Comprise artificial femur handle 1 and bone wall 3; Said artificial femur handle 1 comprises that head and the said artificial hip joint fixture of body are provided with connecting rod, and said connecting rod near-end and head link to each other, far-end extends laterally and parallel with bone wall 3, and the far-end of connecting rod is fixedly connected through lock screw 5 with body., can prevent effectively that artificial femur handle is 1 loosening, sink firm fixing of artificial femur handle 1 and bone wall 3 through connecting rod, prolong artificial hip joint service life greatly, the profile of connecting rod and artificial femur handle 1 is identical, good fixing effect.
Wherein, said head is provided with the groove with connecting rod near-end coupling, and said body is provided with the locking nail hole 4 with lock screw 5 couplings.Groove and connecting rod coupling connect closely, and locking nail hole 4 can well strengthen bonding strength.
Wherein, said connecting rod is provided with limited bayonet 2, and said limited bayonet 2 cooperates with said groove is nested.The groove fit of limited bayonet 2 and artificial femur handle 1, good fixing effect can effectively prevent artificial femur handle 1 loosening, rotation.
Wherein, said limited bayonet 2 is fixedly connected with said groove through gim peg 7.Through gim peg 7 auxiliary fixing, good fixing effect.
Wherein, said limited bayonet 2 limited bayonet 2 that is U-shaped.
Wherein, said artificial hip joint fixture is provided with guide cylinder 6, and said guide cylinder 6 is arranged in said locking nail hole 4, and said lock screw 5 is arranged in the said guide cylinder 6.Locking nail hole 4 can make lock screw 5 wear easily, and is easy to use, and guide cylinder 6 secondary locking screws 5 are arranged in the lock hole, avoids lock screw 5 hour, do not match with lock hole, loosening situation occurs.
Should be noted that at last; Above embodiment is only in order to the technical scheme of explanation this utility model but not to the restriction of this utility model protection domain; Although this utility model has been done detailed description with reference to preferred embodiment; Those of ordinary skill in the art should be appreciated that and can make amendment or be equal to replacement the technical scheme of this utility model, and do not break away from the essence and the scope of this utility model technical scheme.
