Between fracture three types.It is classification of fracture common in elderly population.It is mostly main for the patient without absolute surgical contraindication at present
Open operative treatment.Fracture of neck of femur refers to being broken between femoral head and femur, needs to be connected as one with screw after fracture.China
202477828 U of patent publication No. CN disclose fractured near end of thighbone nail-stick system, including screw rod, and screw head has nail tip,
Screw front end surface is provided with nail tip screw thread, and screw rod end surface is provided with nail tail screw thread, and the end of screw rod is additionally provided with spherical
Nail tail, follow closely tail on be provided with six side's screw channels in spherical nail tail.Nail tail be arranged in the nut of U shapes and be arranged in nut
The surface of spiral shell wedge fits.The main screw that the nail-stick system is mutually parallel by two connects femoral head, neck of femur and femur
It is integrated, two main screws are independent from each other, and after pole falls off, two main screws are also easy to exit, and it is unreliable to there is connection
Defect.In addition, femoral head, neck of femur and femur can only be connected as one, if being broken on femur, can not be connected
It connects, use scope is limited.
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, femur can be connected
The fractured near end of thighbone connector that crack can connect faulted joint on femur, be connected firmly again between head and femur.
The purpose of this utility model is achieved through the following technical solutions：A kind of fractured near end of thighbone connector, it includes
The proximal end of main barred body, the first screw, the second screw and secondary screw, the main barred body offers the first inclined hole and the second inclined hole,
It the lower section of second the first inclined hole of inclined hole position and being connected to the first inclined hole, inclined hole axis and main barred body are in angle setting, and described the
One screw is arranged through the first inclined hole, and the second screw is arranged through the second inclined hole, the spiral shell of the screw thread of the second screw and the first screw
Line is meshed, and the far-end of the main barred body offers threaded hole, and threaded hole internal thread is connected with time screw, the main barred body
Bottom be additionally provided with prong.
The length of first screw is more than the length of the second screw.
The tail portion of first screw and the second screw offers flat recess.
The secondary screw is horizontally disposed.
The utility model has the following advantages：The utility model is compact-sized, can connect between femoral head and femur and split
It stitches the faulted joint that can be connected again on femur, be connected firmly.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the operating diagram of the utility model；
Fig. 3 is the A-A sectional views of Fig. 1；
In figure, the main barred bodies of 1-, the first screws of 2-, the second screws of 3-, 4- screw, the first inclined holes of 5-, the second inclined holes of 6-, 7-
Threaded hole, 8- prongs, 9- flat recesses, 10- femorals head and femur faulted joint, 11- femur faulted joints.
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 Fig. 1 ~ 3, a kind of fractured near end of thighbone connector, it includes main barred body 1, the first screw 2, the second screw 3
The first inclined hole 5 and the second inclined hole 6, the second the first inclined hole 5 of inclined hole 6 are offered with the proximal end of secondary screw 4, the main barred body 1
Lower section and be connected to the first inclined hole 5, inclined hole axis and main barred body 1 are arranged in angle, and first screw 2 is oblique through first
Hole 5 is arranged, and the second screw 3 is arranged through the second inclined hole 6, and the length of the first screw 2 is more than the length of the second screw 3, the second spiral shell
The screw thread of nail 3 is meshed with the screw thread of the first screw 2 to be formed joint self-locking nail and combines, raising stability, and anti-rotation prevents cutting out stubborn
Significant pressure effect is generated when entering pressurization nail.
As shown in Figure 1, the far-end of the main barred body 1 offers threaded hole 7,7 internal thread of threaded hole is connected with time screw
4, secondary screw 4 is horizontally disposed, and the bottom of the main barred body 1 is additionally provided with prong 8, and prong 8 is in hairpin formation, when prong 8 into
After entering in femoral bone cavitas medullaris, stress concentration can be reduced, secondary stock folding around distal femur is avoided, reduces pain.Described
The tail portion of first screw 2 and the second screw 3 offers flat recess 9, in order to which screw is screwed into femoral head.
The course of work of the utility model is as follows：First the prong of main barred body 1 is inserted in femoral bone cavitas medullaris from top to bottom, really
It protects prong 8 and runs through femur faulted joint 11, then through femur and be inserted in the first screw 2 in first inclined hole 5, by its end of thread
It across femoral head and femur faulted joint 11 and is screwed into femoral head, the second screw 3 through femur and is then inserted in second tiltedly
In hole 6, and its end of thread is passed through into femoral head and femur faulted joint 11 and is screwed into femoral head, at the same ensure the first screw 2 with
Second screw 3 constitutes joint self-locking nail, is finally threadedly coupled secondary screw 4 to realize main barred body 1 through femur and with threaded hole 7
Fixation, therefore not only realize and femoral head and femur be connected firmly, and realize and connect femur breaking part, application range
More will be wide, and be connected firmly.
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
