Description

A kind of fracture connector of stable connection
Technical field
The present invention relates to the technical field of attachment structure after fractured near end of thighbone, the fracture of particularly a kind of stable connection connects Connect device.
Background technology
Fractured near end of thighbone includes fracture of neck of femur, intertrochanteric fracture and fracture of neck of femur and merges femoral trochanter Between fracture three types.It is common classification of fracture in elderly population.After being broken between femoral head and femur, generally using main rod Body and screw are attached, and its job step recycles screw to tilt and run through main rod for main barred body is inserted in femoral bone cavitas medullaris Inclined hole on body is simultaneously screwed into femoral head, so as to realize the connection between femoral head and femur.And for different age group patient For, the angle formed between the femur and femoral head of human body is differed, 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 on same straight line with femoral head, Cause in only sub-fraction screw thread wedging femur, there is unstable, the unstable defect of connection.
The content of the invention
It is an object of the invention to the shortcoming for overcoming prior art, there is provided a kind of compact conformation, adjustable angle, connection jail Gu, the fracture connector of stable connection simple to operate.
The purpose of the present invention is achieved through the following technical solutions:A kind of fracture connector of stable connection, it includes master Cavity of the connection at the top of it is offered in barred body and plug, the main barred body, screw thread, plug is offered on the inwall on cavity top External screw thread and cavity on threaded connection, offer on the side wall of the main barred body in the groove through main barred body, groove and pass through Pin-hinges have the steel wire for being fitted with cylinder, cylinder and being provided with and being connected between cylinder and plug in main screw, cavity, institute The bottom for stating main barred body offers prong, and the secondary screw being threadedly coupled with main barred body is provided between prong and groove.
One end of described steel wire is welded at the top of cylinder, and the other end is welded in the bottom of plug.
The axis of described groove is set with main barred body in angle.
The afterbody of described main screw offers flat recess.
Multiple apertures are distributed with the cylinder of described main barred body distal end.
The present invention has advantages below:Compact conformation of the present invention, adjustable angle, be connected firmly, it is simple to operate.
Brief description of the drawings
Fig. 1 is structural representation of the invention;
Fig. 2 is operating diagram of the invention;
In figure, the main barred bodies of 1-, 2- plugs, 3- cavitys, 4- grooves, 5- pins, 6- cylinders, the main screws of 7-, 8- steel wires, 9- prongs, 10- screw, 11- femorals head and femur faulted joint, 12- femur faulted joints.
Embodiment
The present invention will be further described below in conjunction with the accompanying drawings, and protection scope of the present invention is not limited to as described below:
As shown in Figure 1 and 2, the fracture connector of a kind of stable connection, it includes opening in main barred body 1 and plug 2, the main barred body 1 It is communicated with the cavity 3 at the top of it, the inwall on the top of cavity 3 offering screw thread, external screw thread and the spiral shell on cavity 3 of plug 2 Line is connected, and the groove 4 through main barred body 1 is offered on the side wall of the main barred body 1, and the axis of groove 4 is in angle with main barred body 1 Set, via pins 5, which are hinged with cylinder 6, cylinder 6, in groove 4 is fitted with main screw 7, is provided with cavity 3 and is connected to cylinder 6 Steel wire 8 between plug 2, one end of steel wire 8 is welded in the top of cylinder 6, and the other end is welded in the bottom of plug 2, the master The bottom of 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 groove 4.It is described Prong 9 be in hairpin formation, when prong 9 enter femoral bone cavitas medullaris in after, stress concentration can be reduced, it is to avoid two around distal femur Secondary stock folding, reduces pain.
The afterbody of described main screw 7 offers flat recess, is distributed with the cylinder of the described distal end of main barred body 1 multiple small Hole.
The course of work of the present invention is as follows:First prong 9 is inserted in femoral bone cavitas medullaris from top to bottom, cylinder 6 and main 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 threaded connection, then rotates plug 2, and the linear motion of plug 2 drives cylinder 6 to do small angle rotation around pin 5 through steel wire 8, when When cylinder 6 is on same straight line with femoral head, stopped the rotation plug 2, and main screw 7 is finally tilted through into stock from right to left Its threaded portion is simultaneously screwed into femoral head by bone, cylinder 6, femoral head and femur faulted joint 12, it is achieved thereby that femoral head and femur Connection and femur breaking part connection, it is ensured that threaded portion whole wedgings are in femoral head, greatly improving connection Intensity.
Described above is only the 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 the exclusion to other embodiment, and available for various other combinations, modification and environment, and can be at this In the text contemplated scope, it is modified by the technology or knowledge of above-mentioned teaching or association area.And those skilled in the art are entered Capable change and change does not depart from the spirit and scope of the present invention, then all should appended claims of the present invention protection domain It is interior.
