Description
Technical field
The present invention relates to the technical field of backbone solid state support, particularly a kind of spine nail rod fixed system.
Background technology
At present, when after human spine is deformed caused by the reasons such as fracture, lesion, conventional quality method is by performing the operation
Spinal column internal fixation device is installed at deformation of spinal column position to be used to carry out orthopedic and academic title to backbone, is helped backbone to recover function or is delayed disease
Feelings deteriorate.Backbone is the indispensable part of support human body, and backbone is made up of the spinal joint of many series connection, if two neighboring ridge
Vertebral articulations is broken or then human body can be caused not walk when misplacing, it is therefore desirable to connect as one multiple spinal joints.
Spinal joint is connected as one using backbone solid-state system, the system includes barred body and multiple is threadedly connected to rod
Screw composition on body, in use, being screwed into a screw in spinal joint to be fixed, barred body serves supporting role,
It is achieved thereby that being consolidated to backbone, after patient takes good care of through a period of time, spinal joint breaking part can be combined.Because vertebra is closed
Section original structure was impacted, and stress raiser increases, and bone strength certainly will decline, it is necessary to take a long time recovery, exist
The defect of convalescence length.
The content of the invention
It is an object of the invention to overcome the shortcoming of prior art, there is provided a kind of compact conformation, convalescence be short, fix tightly
Gu, improve bone strength spine nail rod fixed system.
The purpose of the present invention is achieved through the following technical solutions：A kind of spine nail rod fixed system, it includes arc rod
Body and spinal joint fixing device, described spinal joint fixing device include offering in cylinder and main screw, the cylinder
Screw plug is threaded with cavity and screwed hole, screwed hole, main screw is fixed on cylinder bottom, main screw through lock-screw
Inside offer and multiple spinal joint fixing devices are provided with runner, described arc barred body, arc barred body through cavities is set
And press between cylinder bottom and screw plug bottom, the upper and lower end parts of arc barred body are sealed, and are opened up in arc barred body
There are the feed pathway set along its length, feed pathway and flow passage.
The head of described main screw and arc barred body are tangent.
The section of described arc barred body is circle.
The upper end of described arc barred body is connected with branch pipe, and branch pipe is connected with feed pathway.
The present invention has advantages below：（1）Compact conformation of the present invention, convalescence are short, improve bone strength.（2）Arc rod
Body is through the cavity of cylinder and the other joint of spinal joint, so that whole system is even integral with backbone, connects more firm
Gu.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
Fig. 2 is Fig. 1 A-A sectional views；
In figure, 1- arc barred bodies, 2- spinal joint fixing devices, 3- cylinders, the main screws of 4-, 5- cavitys, 6- screwed holes, 7- screw threads
Plug, 8- lock-screws, 9- runners, 10- feed pathways, 11- branch pipes, 12- spinal 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, a kind of spine nail rod fixed system, it includes arc barred body 1 and spinal joint fixing device 2, described
Spinal joint fixing device 2 include cylinder 3 and main screw 4, offer cavity 5 and screwed hole 6, screwed hole 6 in the cylinder 3
Place is threaded with screw plug 7, and main screw 4 is fixed in the bottom of cylinder 3, the present embodiment through lock-screw 8, main screw 4
Head extends to both sides, and extension is fixed on cylinder 3 through lock-screw 8.Runner 9, described arc are offered in main screw 4
Be provided with multiple spinal joint fixing devices 2 on barred body 1, the through cavities 5 of arc barred body 1 set and press on the bottom of cylinder 3 with
Between the bottom of screw plug 7, the upper and lower end parts of arc barred body 1 are sealed, and are offered and are set along its length in arc barred body 1
The feed pathway 10 put, feed pathway 10 is connected with runner 9.
As shown in Figure 1 and 2, the head of described main screw 4 and arc barred body 1 are tangent；The section of described arc barred body 1
For circle；The upper end of described arc barred body 1 is connected with branch pipe 11, and branch pipe 11 is connected with feed pathway 10.
The course of work of the present invention is as follows：First the threaded portion of main screw 4 is screwed into spinal joint 12, locking is recycled
The extension of main screw 4 is fixed on cylinder 3 by screw 8, and then arc barred body 1 is passed through to the cavity 5 and spinal joint of cylinder 3
12 other joint, so that whole system is even integral with backbone, connects more firm, then tightens screw plug 7, so that
Screw plug 7 is pressed on arc barred body 1, and ensures that feed pathway 10 is connected with runner 9, finally realizes consolidating for spinal joint
It is fixed.Post operation, calcium fluoride melt solution is added into feed pathway 10 through branch pipe 11, and solution shunt enters in air stream enter runner 9, enters back into vertebra
In joint 12, calcium fluoride melt solution can increase the intensity of bone, supplement bone calcium constituent, accelerate the recovery of patient.
