Abstract
The utility model provides an artifical hip joint prosthesis handle of fracture around treatment false body, belongs to orthopedic medical equipment technical field for fracture around the false body behind the treatment hip replacement. Its technical scheme is: middle section and distal end at the false body handle set up a plurality of fixed orificess, and the fixed orifices runs through the false body handle to the inboard outside the false body handle, and the length central line of fixed orifices is perpendicular with the length direction of false body handle, and a plurality of fixed orificess are parallel to each other. The utility model discloses it has the fixed orifices to reserve on the false body handle, when fracturing, can adopt the steel sheet ligamentopexis merely behind the treatment hip joint replacement around the false body, and it is fixed not need the steel cable ring to prick. Two -layer cortex is fastened inside and outside around fixed orifices that steel sheet set screw can pass the reservation and the femoral fracture, reaches good fixed effect, its mechanics stability greatly increased. The utility model discloses simple structure, convenient to use make the fixed stability, firm at the position of fracturing around the false body handle, reach the surgery effect of ideal, very are favorable to patient's recovery and functional recovery.
Description
Technical field
This utility model relates to a kind of artificial hip prosthesis's handle being used for the treatment of hip replacement Periprosthetic fracture, belongs to orthopedic medical device technical field.
Background technology
In person in middle and old age's orthopedics patient, that suffers from hip joint disease occupies significant proportion, wherein mainly the femur head necrosis that causes of a variety of causes and the fracture of femoral neck that causes because falling.Along with the raising of people's living standard and the continuous enhancing of health idea, patient carries out hip replacement quantity constantly to be increased, for thorough radical curing of disease and recovery hip joint function provide best treatment means.But, along with the increase of hip replacement quantity, the incidence rate of postoperative Periprosthetic Fracture After Total Hip Arthroplasty also significantly increases, caused by the external force such as its reason mostly is wrestling, fall, postoperative Periprosthetic Fracture After Total Hip Arthroplasty, along with very high disability rate and other serious consequence, needs to treat in time.Periprosthetic fracture the most common clinically occurs in the fracture of femoral stem far-end, and such fracture is also the difficult point of clinical treatment.Because patient mostly is old people, generally all merge osteoporosis, therefore the steel plate that adopts is treated in conjunction with wirerope cerclage fixing operation more clinically, but because prosthesis handle is in the occupy-place of near end of thighbone pulp cavity, during Interal fixation, mono cortex screw can only be inserted, have impact on the stability of Interal fixation, and use wirerope cerclage to fix, certainly will affect the blood fortune of corresponding site, therefore, surgical effect is not satisfactory.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of artificial hip prosthesis's handle for the treatment of Periprosthetic fracture, this prosthesis handle can not only be used for first artificial hip joint replacing, and the successive treatment be applicable to when there is fracture around artificial hip prosthesis, make fracture site fixation, stablize, reach desirable surgical effect.
The technical scheme solved the problems of the technologies described above is:
A kind of artificial hip prosthesis's handle for the treatment of Periprosthetic fracture, in the stage casing of prosthesis handle and far-end, multiple fixing hole is set, fixing hole runs through prosthesis handle inside prosthesis handle lateral, fixing hole is 2-5, the lengthwise centers line of fixing hole is vertical with the length direction of prosthesis handle, and the lengthwise centers line of multiple fixing hole is parallel to each other.
Artificial hip prosthesis's handle of above-mentioned treatment Periprosthetic fracture, described fixing hole is elongated hole, the length direction of elongated hole is along the length direction of prosthesis handle, and the length of the length direction of elongated hole is greater than the diameter of Interal fixation screw, and the length of the transverse direction of elongated hole and the diameter of Interal fixation screw match.
The beneficial effects of the utility model are:
This utility model is reserved with fixing hole on original prosthesis handle, after treating hip replacement during Periprosthetic fracture, can adopt fixation merely, not need wirerope cerclage to fix.Interal fixation screw can carry out fastening through two-layer cortex inside and outside around reserved fixing hole and the fracture of femur, reach good fixed effect, this can only penetrate for one deck cortical bone of outside relative to screw after traditional prosthesis handle surrounding fracture, and its mechanical stability increases greatly; And the long hole shape design of fixing hole does not produce stress shielding, and just with the fine setting of steel plate locus, Interal fixation screw is inserted smoothly.This utility model structure is simple, easy to use, is applicable to treatment when there is fracture around prosthesis handle, makes the fixing-stable of fracture site, firmly, reaches rehabilitation and functional rehabilitation that desirable surgical effect is extremely conducive to patient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the side view of Fig. 1;
Fig. 3 is using state schematic diagram of the present utility model.
In figure, labelling is as follows: prosthesis handle 1, fixing hole 2, femur 3, steel plate 4, hold-down screw 5.
Detailed description of the invention
This utility model is made up of prosthesis handle 1, fixing hole 2.
Show in figure, in the stage casing of prosthesis handle 1 and far-end, multiple fixing hole 2 is set, fixing hole 2 runs through prosthesis handle 1 inside prosthesis handle 1 lateral, and the lengthwise centers line of fixing hole 2 is vertical with the length direction of prosthesis handle 1, and the lengthwise centers line of multiple fixing hole 2 is parallel to each other.
In the treatment, Interal fixation screw 5 can carry out fastening through two-layer cortex inside and outside around fixing hole 2 reserved on prosthesis handle 1 and the fracture of femur 3, reaches good fixed effect.
Show in figure, fixing hole 2 is 2-5, and preferred amount is 3.The quantity of the fixing hole 2 of embodiment of the present utility model is 3.
Show in figure, fixing hole 2 is elongated hole, and the length direction of elongated hole is along the length direction of prosthesis handle 1, and the length of the length direction of elongated hole is greater than the diameter of Interal fixation screw 5, and the length of the transverse direction of elongated hole and the diameter of Interal fixation screw 5 match.The advantage that fixing hole 2 adopts long hole shape to design does not produce stress shielding, and just with the fine setting of steel plate 4 locus, Interal fixation screw 5 is inserted smoothly.
