Description
Technical field
The technical field for the hip prosthesis structure that come off the present invention relates to anti-acetabular bone, the hip that particularly a kind of anti-acetabular bone comes off
Articular prosthesis.
Background technology
At present, with the continuous renewal of China's medical device technology, particularly in field of orthopaedics, artificial hip joint replacing hand
A kind of art, it has also become effective ways for generally using of medical field treatment hip joint disabling disease, and the acetabular bone of Post operation implantation and
Fixed effect between femoral stem and natural bone is the key for determining joint prosthesis service life and curative effect.Hip prosthesis is imitative
What the structure according to human hip was made, acetabular bone, bulb and femoral stem are generally included, femoral stem is inserted to the femoral bone cavitas medullaris of lower limb
It is interior, between bulb and acetabular bone cooperate after and be fixed in human pelvis acetabular fossa so that the song of simulated implementation femur stretch and
Motion.Acetabular bone is in basin acetabular fossa after long-term rotation, and acetabular bone easily comes off from bulb, causes patient's second hurt, further
Add surgery cost.
For the patient of different age group, level interval is each unequal between the pelvis acetabular fossa and femur of patient,
Therefore many set prosthese moulds are needed, cost is too high, even if being installed to after human body, and patient can also feel incomparable pain, influence
The recovery of patient.
The content of the invention
It is an object of the invention to overcome the shortcoming of prior art there is provided a kind of compact conformation, suitable for different age group
Patient, service life length, effectively prevent acetabular bone from coming off, reduce the hip prosthesis that the anti-acetabular bone of cost of manufacture comes off.
The purpose of the present invention is achieved through the following technical solutions：The hip prosthesis that a kind of anti-acetabular bone comes off, it includes
Femoral stem, neck of femur and bulb, the close end of described femoral stem are installed with neck of femur, and the other end of neck of femur offers screw thread
Hole, screwed hole internal thread is connected with threaded rod, and the other end of threaded rod is provided with bulb, and the outside of bulb is provided with acetabular bone, institute
Two antirust guiding principle silks are fixed between the acetabular bone and neck of femur stated, one end of antirust guiding principle silk is fixed on the bottom face of acetabular bone, prevented
The other end of rust guiding principle silk is fixed on the top of neck of femur.
Two described antirust guiding principle silks are symmetrical arranged on neck of femur.
The basal surface of described acetabular bone is provided with earrings.
One end of described antirust guiding principle silk is connected on earrings.
Uniformly aperture, a diameter of 0.4 ~ 0.8 micron of aperture are offered on the cylinder of described femoral stem distal end.
The present invention has advantages below：Compact conformation of the present invention, suitable for different age group patient, service life length, have
Effect prevents acetabular bone from coming off, reduces cost of manufacture.
Brief description of the drawings
Fig. 1 is structural representation of the invention
In figure, 1- femoral stems, 2- necks of femur, 3- bulbs, 4- screwed holes, 5- threaded rods, 7- acetabular bones, 8- antirusts guiding principle silk, 9- ears
Ring.
Embodiment
The present invention will be further described below in conjunction with the accompanying drawings, and protection scope of the present invention is not limited to as described below：
As shown in figure 1, the hip prosthesis that a kind of anti-acetabular bone comes off, it includes femoral stem 1, neck of femur 2 and bulb 3, described
The close end of femoral stem 1 is installed with neck of femur 2, and the other end of neck of femur 2 offers screwed hole 4, and the internal thread of screwed hole 4 is connected with
Threaded rod 5, the other end of threaded rod 5 is provided with bulb 3, and the outside of bulb 3 is provided with acetabular bone 7.As shown in figure 1, described hip
Two antirust guiding principle silks 8 are fixed between mortar 7 and neck of femur 2, two antirust guiding principle silks 8 are symmetrical arranged on neck of femur 2, antirust guiding principle silk
8 one end is fixed on the bottom face of acetabular bone 7, and the other end of antirust guiding principle silk 8 is fixed on the top of neck of femur 2, therefore in antirust
The pulling force effect of guiding principle silk 8, acetabular bone 7 coordinates with bulb 3 all the time, it is to avoid acetabular bone is long-term when rotating in basin acetabular fossa, acetabular bone from
Come off on bulb, extend the service life of the prosthese.
As shown in figure 1, the basal surface of described acetabular bone 7 is provided with earrings 9, one end of described antirust guiding principle silk 8 is connected to
On earrings 9.Uniformly aperture, a diameter of 0.4 ~ 0.8 micron of aperture, micropore are offered on the cylinder of the described distal end of femoral stem 1
The bio-intermiscibility with bone can be increased, increase adhesion, accelerate the recovery of patient.
The course of work of the present invention is as follows：During operation, acetabular bone 7 is used to be installed in patient's pelvis acetabular fossa, and osteopathy handle 1 is pacified
In femoral bone cavitas medullaris loaded on lower limb, you can realize the installation of the hip prosthesis.If water between patient's pelvis acetabular fossa and femur
Flat spacing is shorter, then turning threaded rod 5 makes it be threaded into hole 4, if level interval between patient's pelvis acetabular fossa and femur
Longer, then turning threaded rod 5 makes it back-out from screwed hole 4.Therefore, it is applicable on different age group patient that the vacation is installed
Body, facilitates the distance between adjusting ball head and femoral stem, and without die sinking manufacture, reduce manufacturing cost.
Described above is only the preferred embodiment of the present invention, it should be understood that the present invention is not limited to described herein
Form, is not to be taken as the exclusion to other embodiment, and available for various other combinations, modification and environment, and can be at this
In the text contemplated scope, it is modified by the technology or knowledge of above-mentioned teaching or association area.And those skilled in the art are entered
Capable change and change does not depart from the spirit and scope of the present invention, then all should appended claims of the present invention protection domain
It is interior.
