Description
Technical field
The utility model relates to the technical field of backbone solid state support, especially a kind of spinal stabilization device.
Background technique
Currently, common quality method is existed by operation after human spine deforms caused by because of reasons such as fracture, lesions
Deformation of spinal column position installs spinal column internal fixation device and is used to carry out orthopedic and academic title to backbone, helps backbone to restore function or delays disease
Feelings deteriorate.Backbone is the support indispensable part of human body, and backbone is made of more concatenated spinal joints, if two neighboring ridge
Then will lead to human body when vertebral articulations fracture or dislocation can not walk, it is therefore desirable to be connected as one multiple spinal joints.Using
Spinal joint is connected as one by backbone solid-state system, which includes barred body and multiple screw groups being threadedly connected on barred body
It is arranged at, screw perpendicular to barred body, in use, be screwed into a screw in spinal joint to be fixed, to realize pair
Backbone consolidates, and for patient after raising for a period of time, spinal joint breaking part can be compound.However, the patient of different age group
For angle between spinal joint be it is different, using common screw only have it is oblique be screwed into spinal joint, screw
It is in angle with spinal joint face, therefore is difficult to be screwed into spinal joint, it is time-consuming and laborious, and also connection is also not secured enough, returns trouble
Person's bring pain.
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, convalescence is short, connection
Securely, it saves and is screwed into power, suitable for the spinal stabilization device of different age group patient.
The purpose of this utility model is achieved through the following technical solutions：A kind of spinal stabilization device, it includes that vertebra closes
Fixed device and barred body are saved, the fixed device of the spinal joint includes cylinder, main screw and bulb, offers cavity in cylinder
And threaded hole, threaded hole are connected to cavity, threaded hole is located above cavity, is threaded with pressure head at threaded hole, sets in cavity
It is equipped with fixing seat, spherical cavity is offered in fixing seat, bulb engaged therewith is installed in spherical cavity, bulb internal screw thread connects
It is connected to main screw, main screw extends outside cylinder, and through there are multiple cylinders on the barred body, barred body presses on main head of screw
Between portion and pressure head bottom.
The section of the barred body is circle.
The cylinder is cylindrical shape.
The barred body is horizontally disposed.
The utility model has the following advantages that：The utility model is compact-sized, convalescence is short, is connected firmly, saves and be screwed into
Power is suitable for different age group patient.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model
Fig. 2 is the A-A cross-sectional view of Fig. 1；
Fig. 3 is the operation schematic diagram of the utility model；
In figure, the fixed device of 1- spinal joint, 2- barred body, 3- cylinder, the main screw of 4-, 5- bulb, 6- threaded hole, 7- pressure
Head, 8- fixing seat, 9- spinal joint.
Specific embodiment
The utility model is further described with reference to the accompanying drawing, the protection scope of the utility model be not limited to
It is lower described：
As shown in Figure 1, a kind of spinal stabilization device, it includes the fixed device 1 of spinal joint and barred body 2, the vertebra
Arthrodesis device 1 includes cylinder 3, main screw 4 and bulb 5, offers cavity and threaded hole 6, threaded hole 6 and chamber in cylinder 3
Body connection, threaded hole are located above cavity, are threaded with pressure head 7 at threaded hole 6, fixing seat 8, fixing seat are provided in cavity
Spherical cavity is offered in 8, bulb 5 engaged therewith is installed in spherical cavity, and bulb 5 can rotate in spherical cavity, ball
First 5 internal screw thread is connected with main screw 4, and main screw 4 extends outside cylinder 3, through there is multiple cylinders 3 on the barred body 2, originally
In embodiment, there are two the fixed devices 1 of spinal joint, barred body 2 to press on main 4 head of screw and 7 bottom of pressure head for setting on barred body 2
Between.The section of the barred body 2 is circle；The cylinder 3 is cylindrical shape；The barred body 2 is horizontally disposed.
The course of work of the utility model 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, barred body 2 is sequentially passed through two ridges after main screw 4 is screwed into
Pressure head 7 is finally tightened in region between the pressure head 7 and main screw 4 of the fixed device 1 of vertebral articulations, and pressure head 7 presses on 2 top of barred body,
Realize 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 rotating ball
First 5 make main screw 4 be adjusted to vertical with spinal joint 9, as shown in figure 3, being then screwed into main screw 4, barred body 2 is sequentially worn
The region between the pressure head 7 and main screw 4 of the fixed device 1 of two spinal joints is crossed, finally tightens pressure head 7, pressure head 7 presses on stick
2 top of body, realizes the fixation of the stabilising arrangement.It can thus be appreciated that the device is suitably applied the pass of the vertebra with different angle
Section, will not pain after installation.
