Description
Technical field
The utility model is related to the technical field of borrowed structure, especially a kind of hip prosthesis.
Background technology
In recent years, artificial joint replacement is one of the most important progress that field of orthopaedics obtains, with China's medical instrument
The continuous renewal of technology, especially in field of orthopaedics, artificial hip joint replacing operation, it has also become medical field treatment hip joint is disabled
A kind of effective ways that disease generally uses, and the fixed effect after performing the operation between the acetabular bone being implanted into and femoral stem and natural bone is
Determine the key of joint prosthesis service life and curative effect.Hip prosthesis is to copy made of the structure of human hip, usually
Including acetabular bone, bulb and femoral stem, femoral stem is inserted into the femoral bone cavitas medullaris of lower limb, after cooperating between bulb and acetabular bone simultaneously
It is fixed in human pelvis acetabular fossa, stretches and move to the song of simulated implementation femur.For under the patient of different age brackets
The length of limb femoral bone cavitas medullaris is different, and level interval is each unequal between the pelvis acetabular fossa and femur of patient, therefore needs
To cover prosthese molding die, cost is excessively high more.Even if the hip prosthesis can be felt incomparably to ache if being installed to patient after human body
Bitterly, it can not adapt to, influence the recovery of patient.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the prior arts, provide it is a kind of it is compact-sized, be suitable for not the same year
Age section patient, the hip prosthesis that pain, reduction low manufacture cost will not be brought to patient.
The purpose of this utility model is achieved through the following technical solutions：A kind of hip prosthesis, it includes femoral stem, stock
The distal end of bone neck and bulb, the femoral stem offers threaded hole B, and threaded hole B internal threads are connected with threaded rod B, threaded rod B
Lower part be connected with the conical head extended outside threaded hole B, on the conical head and along its length on offer it is more
Groove, the proximal end of the femoral stem are provided with neck of femur, and the other end of neck of femur offers threaded hole A, spiral shell in threaded hole A
Line is connected with threaded rod A, and the other end of threaded rod A is provided with bulb, and the outside of bulb is equipped with acetabular bone.
Spacing between the groove is equal.
The groove is arranged obliquely.
The depth of the groove is 0.5 ~ 1mm.
The utility model has the following advantages：The utility model is compact-sized, suitable for different age group patient, will not give
Patient brings pain, reduces low manufacture cost.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
In figure, 1- femoral stems, 2- necks of femur, 3- bulbs, 4- threaded holes B, 5- threaded rod B, 6- conical head, 7- grooves, 8-
Threaded hole A, 9- threaded rod A, 10- acetabular bone.
Specific implementation mode
The utility model is further described below in conjunction with the accompanying drawings, the scope of protection of the utility model be not limited to
It is lower described：
As shown in Figure 1, a kind of hip prosthesis, it includes femoral stem 1, neck of femur 2 and bulb 3, the femoral stem 1
Distal end offers threaded hole B4, and threaded hole B4 internal threads are connected with threaded rod B5, and the lower part of threaded rod B5, which is connected with, extends spiral shell
Conical head 6 outside pit B4, on the conical head 6 and along its length on offer a plurality of groove 7, the femur
The proximal end of handle 1 is provided with neck of femur 2, and the other end of neck of femur 2 offers threaded hole A8, and threaded hole A8 internal threads are connected with screw thread
The other end of bar A9, threaded rod A9 are provided with bulb 3, and the outside of bulb 3 is equipped with acetabular bone 10.
Spacing between the groove 7 is equal, and the groove 7 is arranged obliquely, and the depth of the groove 7 is
0.5 ~ 1mm, groove 7 can increase the binding force of femoral stem 1 and femoral bone cavitas medullaris, increase the bio-intermiscibility of femoral stem and bone,
Binding force increases, and accelerates patient and restores.
The course of work of the present invention is as follows：When operation, acetabular bone 10 is for being installed in patient's pelvis acetabular fossa, osteopathy handle 1
It is installed in the femoral bone cavitas medullaris of lower limb, you can realize the installation of the hip prosthesis.If patient's lower limb femoral bone cavitas medullaris length is longer,
Then turning threaded rod B5 makes it back-out from threaded hole B4, if patient's lower limb femoral bone cavitas medullaris length is shorter, turning threaded rod B5 makes
It is threaded into the B4 of hole；If level interval is longer between patient's pelvis acetabular fossa and femur, turn threaded rod A9 make its from
Threaded hole A8 back-outs, if level interval is shorter between patient's pelvis acetabular fossa and femur, turning threaded rod A9 makes it be screwed into spiral shell
In pit A8.Therefore, be applicable to that the prosthese is installed on different age group patient, facilitate adjust femoral stem 1 length and its
With the spacing between bulb 3, and without mold manufacture, reduce manufacturing cost.
The above is only a 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 excluding other embodiments, and can be used for other combinations, modifications, and environments, and can be at this
In the text contemplated scope, modifications can be made through the above teachings or related fields of technology or knowledge.And those skilled in the art institute into
Capable modifications and changes do not depart from the spirit and scope of the present invention, then all should be in the protection domain of appended claims of the present invention
It is interior.
