Abstract
The invention discloses a proximal femur double-shaft locking plate for treating femoral fractures. The proximal femur double-shaft locking plate comprises a locking plate body. The locking plate body is provided with a locking hole, a pressurizing hole, and a locating hole. The pressurizing hole is arranged between the locking hole and the locating hole. The upper end of the inner wall of the locking hole is a smooth inner wall. The lower end of the inner wall of the locking hole is provided with an oblique cone thread by lathing. The upper end of the inner wall of the locating hole is provided with a thread by lathing; and the lower end of the inner wall of the locating hole is provided with an arc-shaped groove. The proximal femur double-shaft locking plate is simple in structure, reasonable in design, and convenient in operation. The oblique cone thread at the lower end of the inner wall of the locking hole allows the locking plate to be more securely fixed on the femur without easily disengaging therefrom.
Description
Technical field
The present invention relates to orthopedic medical device technical field, especially a kind of near end of thighbone twin shaft lockplate being used for the treatment of Fracture of femur.
Background technology
Near end of thighbone comprises the rotor of femoral head, neck of femur and femur.The fracture at neck of femur and rotor position is easily caused when this position is subject to indirectly rotating external force, this situation has more present old people, simultaneously, this position is also the predilection site of many primary bone tumors and the multiple district of Secondary cases metastatic carcinoma, it is easily produce pathologisch Bruch that this position sclerotin is subject to tumor invading.Along with aged tendency of population, incidence rate is global increase trend.Traditional remedies is bed row suffering limb index, but the hospital stays of patient is long, complication rate and mortality rate higher, comparatively mostly occur after healing coxa vara, outward turning shortened deformity or knee stiffness.Therefore, the Lockplate for proximal end of femoral bones that adopts carries out internal fixation treatment more in recent years, and Lockplate for proximal end of femoral bones is provided with lock hole, lock hole is common through hole, and bed knife is not enough, makes the easy slippage of lockplate, not only cause suffering to patient, and be unfavorable for the healing of fracture.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiencies in the prior art, provides a kind of structure simple, the near end of thighbone twin shaft lockplate of fixation
The technical solution adopted for the present invention to solve the technical problems is: a kind of near end of thighbone twin shaft lockplate, comprises lockplate main body, and described lockplate main body is provided with lock hole, pressurization hole and locating hole, and described pressurization hole is between lock hole and locating hole; Described lock hole inwall upper end is smooth inner wall, and described lock hole inwall lower end car has oblique cone screw thread.
Further, described lock hole top is the first tilted prick hole section, is straight hole section below described first tilted prick hole section, is the second tilted prick hole section below described straight hole section, be oblique cone screwed hole section below described second tilted prick hole section, described oblique cone screw thread is positioned at oblique cone screwed hole section.
Further, described pressurization hole is the threaded inclined hole of inwall car.
Further, described locating hole inwall upper end car has screw thread, and the bottom of thread of described locating hole is provided with the groove of arc.
Further, described lock hole is provided with three, and described pressurization hole is provided with two, and described locating hole is provided with one, makes lockplate and femur fix more firm.
The invention has the beneficial effects as follows: structure of the present invention is simple, reasonable in design, easy to operate, lock hole inwall lower end is provided with oblique cone screw thread, more firmly not easily slippage when lockplate and femur are fixed, and locating hole lower end is provided with the groove of arc, the contact area between lockplate and femur can be reduced, make blood flow unimpeded, reduce damage, thus strengthen stock symphysis.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is front view of the present invention;
Fig. 2 be in Fig. 1 A-A to sectional view;
Fig. 3 be in Fig. 1 B-B to sectional view;
Fig. 4 be in Fig. 1 C-C to sectional view.
Wherein: 1. lockplate main body, 2. lock hole, 3. pressurize hole, 4. locating hole, 5. oblique cone screw thread, 6. groove.
Detailed description of the invention
The present invention is further illustrated by reference to the accompanying drawings now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present invention in a schematic way, and therefore it only shows the formation relevant with the present invention.
Near end of thighbone twin shaft lockplate as Figure 1-4, comprises lockplate main body 1, and lockplate main body 1 is provided with lock hole 2, pressurization hole 3 and locating hole 4, and pressurization hole 3 is between lock hole 2 and locating hole 4; Lock hole 2 inwall upper end is smooth inner wall, and lock hole 2 inwall lower end car has oblique cone screw thread 5; Locating hole 4 inwall upper end car has screw thread, and the bottom of thread is provided with the groove 6 of arc.
Lock hole 2 top is the first tilted prick hole section, is straight hole section below described first tilted prick hole section, is the second tilted prick hole section below described straight hole section, and be oblique cone screwed hole section below described second tilted prick hole section, described oblique cone screw thread 5 is positioned at oblique cone screwed hole section.
Pressurization hole 3 is the threaded inclined hole of inwall car, and lock hole 2 is provided with three, and pressurization hole 3 is provided with two, and locating hole 4 is provided with one.
Before using, due near end of thighbone twin shaft lockplate and screw sterilized, must clean and stringent sterilization with water for injection; During use, doctor should develop programs according to the concrete condition of patient, mounting screw in lock hole 2, and pressurizeing, hole 3 is oblique is provided with screw, is provided with screw, is fixed on femur by near end of thighbone twin shaft lockplate in locating hole 4.
This near end of thighbone twin shaft lockplate structure is simple, easy to operate, lock hole 2 inwall lower end is provided with oblique cone screw thread 5, more firmly not easily slippage when lockplate and femur are fixed, locating hole 4 lower end is provided with the groove 6 of arc, can reduce the contact area between lockplate and femur, makes blood flow unimpeded, reduce damage, thus strengthen stock symphysis.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content in description, must determine its technical scope according to right.
