Description
Technical field
The present invention relates to the technical field of backbone solid state support, particularly a kind of spinal stabilization device.
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.Using
Backbone solid-state system connects as one spinal joint, and the system includes barred body and multiple screw groups being threadedly connected on barred body
Into screw is set perpendicular to barred body, in use, a screw is screwed into spinal joint to be fixed, it is achieved thereby that right
Backbone it is firm, after patient takes good care of through a period of time, spinal joint breaking part can be combined.However, the patient of different age group
For angle between spinal joint be different, be screwed into using common screw is only oblique in spinal joint, screw
It is in angle with spinal joint face, therefore is difficult to be screwed into spinal joint, waste time and energy, and connect also not firm enough, returns trouble
The pain that person brings.
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, connection is firm
Gu, save be screwed into power, the spinal stabilization device suitable for different age group patient.
The purpose of the present invention is achieved through the following technical solutions：A kind of spinal stabilization device, it is solid including spinal joint
Determine device and barred body, described spinal joint fixing device includes offering cavity and spiral shell in cylinder, main screw and bulb, cylinder
Pit, screwed hole is connected with cavity, and screwed hole is located above cavity, is threaded with pressure head, cavity and is provided with screwed hole
The bulb for being provided with and coordinating with it in spherical cavity, spherical cavity is offered in fixed seat, fixed seat, bulb internal thread is connected with
Main screw, main screw is extended outside cylinder, through there is multiple cylinders on described barred body, barred body press on main screw head with
Between pressure head bottom.
The section of described barred body is circle.
Described cylinder is cylindrical shape.
Described barred body is horizontally disposed with.
The present invention has advantages below：Compact conformation of the present invention, convalescence is short, is connected firmly, saves and be screwed into power, be applied to
Different age group patient.
Brief description of the drawings

Fig. 2 is Fig. 1 A-A sectional views；
Fig. 3 is operating diagram of the invention；
In figure, 1- spinal joint fixing devices, 2- barred bodies, 3- cylinders, the main screws of 4-, 5- bulbs, 6- screwed holes, 7- pressure heads, 8-
Fixed seat, 9- 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, a kind of spinal stabilization device, it includes spinal joint fixing device 1 and barred body 2, described spinal joint
Fixing device 1 includes offering cavity and screwed hole 6 in cylinder 3, main screw 4 and bulb 5, cylinder 3, and screwed hole 6 connects with cavity
Logical, screwed hole is located above cavity, is threaded with screwed hole 6 in pressure head 7, cavity and is provided with fixed seat 8, in fixed seat 8
The bulb 5 for being provided with and coordinating with it in spherical cavity, spherical cavity is offered, bulb 5 can be rotated in spherical cavity, bulb 5
Internal thread is connected with main screw 4, and main screw 4 is extended outside cylinder 3, and running through on described barred body 2 has multiple cylinders 3, this reality
Apply in example, be provided with two spinal joint fixing devices 1 on barred body 2, barred body 2 press on the main head of screw 4 and the bottom of pressure head 7 it
Between.The section of described barred body 2 is circle；Described cylinder 3 is cylindrical shape；Described barred body 2 is horizontally disposed with.
The course of work of the present invention is as follows：If angle is equal to 180 degree between the face face of the spinal joint 9 of patient, first make
Main screw 4 is vertical to be screwed into spinal joint 9, as shown in figure 1, after main screw 4 is screwed into, barred body 2 is sequentially closed through two vertebras
The region between the pressure head 7 and main screw 4 of fixing device 1 is saved, pressure head 7 is finally tightened, pressure head 7 presses on the top of barred body 2, realized
The fixation of the stabilising arrangement.If angle is less than 180 degree between the face face of the spinal joint 9 of patient, first make rotation bulb 5
Main screw 4 is adjusted to vertical with spinal joint 9, as shown in figure 3, being then screwed into main screw 4, barred body 2 is sequentially passed through into two
Region between the pressure head 7 and main screw 4 of spinal joint fixing device 1, finally tightens pressure head 7, and pressure head 7 presses on barred body 2 and pushed up
Portion, realizes the fixation of the stabilising arrangement.It can thus be appreciated that the device is suitably applied the spinal joint with different angles, install
After will not pain.
