Description
Technical field
The utility model is related to the technical field of connection structure after fractured near end of thighbone, especially a kind of bone of stable connection
Roll over connector.
Background technology
Fractured near end of thighbone includes that fracture of neck of femur, intertrochanteric fracture and fracture of neck of femur merge femoral trochanter
Between fracture three types.It is classification of fracture common in elderly population.After being broken between femoral head and femur, the main stick of generally use
Body and screw are attached, and work step is that main barred body is inserted in femoral bone cavitas medullaris, are recycled screw to tilt and are run through main stick
Inclined hole on body is simultaneously screwed into femoral head, to realize the connection between femoral head and femur.And for different age group patient
For, the angle that is formed between the femur and femoral head of human body is different, and the angle between inclined hole axis and main barred body
It is constant, after barred body is inserted in femoral bone cavitas medullaris, it may appear that the inclined hole on main barred body is not in femoral head on same straight line,
Cause in only sub-fraction screw thread wedging femur, there is unstable, the unstable defect of connection.
Utility model content
The shortcomings that the purpose of the utility model is to overcome the prior arts provides compact-sized one kind, adjustable angle, company
Connect the fracture connector of stable connection secured, easy to operate.
The purpose of this utility model is achieved through the following technical solutions：A kind of fracture connector of stable connection, it is wrapped
Main barred body and plug are included, the cavity being connected at the top of it is offered in the main barred body, screw thread is offered on the inner wall on cavity top,
Threaded connection on the external screw thread and cavity of plug offers the straight slot through main barred body, straight slot on the side wall of the main barred body
Interior via pins are hinged with cylinder, and main screw is fitted in cylinder, the steel being connected between cylinder and plug is provided in cavity
Silk, the bottom of the main barred body offers prong, the secondary screw being threadedly coupled with main barred body is provided between prong and straight slot.
One end of the steel wire is welded at the top of cylinder, and the other end is welded in the bottom of plug.
The axis of the straight slot is arranged with main barred body in angle.
The tail portion of the main screw offers flat recess.
Multiple apertures are distributed on the cylinder of the main barred body distal end.
The utility model has the following advantages：The utility model is compact-sized, adjustable angle, is connected firmly, operates letter
It is single.
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；
In figure, the main barred bodies of 1-, 2- plugs, 3- cavitys, 4- straight slots, 5- pins, 6- cylinders, the main screws of 7-, 8- steel wires, 9- forks
Mouth, 10- screw, 11- femorals head and femur faulted joint, 12- 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 Figure 1 and 2, the fracture connector of a kind of stable connection, it includes main barred body 1 and plug 2, the main barred body 1
Inside offer cavity 3 of the connection at the top of it, offer screw thread on the inner wall on 3 top of cavity, the external screw thread of plug 2 on cavity 3
Threaded connection, the straight slot 4 through main barred body 1 is offered on the side wall of the main barred body 1, the axis of straight slot 4 is in main barred body 1
Angle is arranged, and via pins 5 are hinged with cylinder 6 in straight slot 4, and main screw 7 is fitted in cylinder 6, is provided with and is connected in cavity 3
One end of steel wire 8 between cylinder 6 and plug 2, steel wire 8 is welded in 6 top of cylinder, and the other end is welded in the bottom of plug 2, institute
The bottom for stating main barred body 1 offers prong 9, and the secondary screw 10 being threadedly coupled with main barred body 1 is provided between prong 9 and straight slot 4.
The prong 9 is in hairpin formation, after prong 9 enters in femoral bone cavitas medullaris, can reduce stress concentration, avoids distal femur all
Secondary stock folding is enclosed, pain is reduced.
The tail portion of the main screw 7 offers flat recess, is distributed on the cylinder of 1 distal end of main barred body multiple small
Hole.
The course of work of the utility model is as follows：First prong 9 is inserted in femoral bone cavitas medullaris from top to bottom, cylinder 6 and master
Barred body 1 together enter femoral bone cavitas medullaris in, it is ensured that prong 9 run through femur faulted joint 12, then by secondary screw 10 through femur and with
Main barred body 1 is threadedly coupled, and then rotates plug 2, and the linear motion of plug 2 drives cylinder 6 to do low-angle around pin 5 through steel wire 8
Rotation, when cylinder 6 is in femoral head on same straight line, stop rotating plug 2, finally tilts main screw 7 from right to left
Across femur, cylinder 6, femoral head and femur faulted joint 12 and its threaded portion is screwed into femoral head, to realize femoral head
The connection of connection and femur breaking part with femur, it is ensured that threaded portion whole wedging is greatly improved in femoral head
Bonding strength.
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.
