Abstract
The invention discloses a kind of spinal joint inner fixing device, it includes arc rod（1）, described arc rod（1）Multiple main screws are threaded with above and successively along its length（2）, main screw（2）Quantity and spinal joint（3）Quantity it is equal, arc rod（1）Top be connected with epicone forming head（4）, arc rod（1）Bottom be connected with inferior pyramidal head（5）, epicone forming head（4）With inferior pyramidal head（5）Surface on several micropores, described arc rod are distributed with（1）Curvature it is equal with the curvature of backbone.The beneficial effects of the invention are as follows：Compact conformation, short convalescence, firm and reliable connection, reduction patient pain.
Description
Technical field
The present invention relates to the technical field of backbone solid state support, particularly a kind of spinal joint inner fixing 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.
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.It is that dotted line is fixed, once barred body is by the external world but barred body is locked by screw
Hit, still easily release, cause second hurt, there is the unstable defect of connection.
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 is short, be connected firmly
Reliably, the spinal joint inner fixing device of patient pain is reduced.
The purpose of the present invention is achieved through the following technical solutions：A kind of spinal joint inner fixing device, it includes arc
Multiple main screws are threaded with rod, described arc rod and successively along its length, and quantity and the vertebra of main screw are closed
The quantity of section is equal, and the top of arc rod is connected with epicone forming head, and the bottom of arc rod is connected with inferior pyramidal head, epicone forming head and
Several micropores are distributed with the surface of inferior pyramidal head, the curvature of described arc rod is equal with the curvature of backbone.
The section of described arc rod is circle.
A diameter of 0.4 ~ 0.6 micron of described micropore.
The present invention has advantages below：Compact conformation of the present invention, short convalescence, firm and reliable connection, reduction patient pain.
Brief description of the drawings
Fig. 1 is structural representation of the invention；
Fig. 2 is the structural representation of inferior pyramidal head；
In figure, 1- arc rods, the main screws of 2-, 3- spinal joints, 4 epicone forming heads-, 5- inferior pyramidal heads, 6- sides joint, 7- basin bones.
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 spinal joint inner fixing device, it includes growing on arc rod 1, described arc rod 1 and along it
Degree direction is threaded with multiple main screws 2 successively, and the quantity of main screw 2 is equal with the quantity of spinal joint 3, arc rod 1
Top is connected with epicone forming head 4, and the bottom of arc rod 1 is connected with inferior pyramidal first 5, on the surface of epicone forming head 4 and inferior pyramidal first 5
Several micropores are distributed with, micropore can increase the bio-intermiscibility of conical head and bone, improve adhesion, it is ensured that arc rod 1
More it is firmly fixed, it is ensured that the fast quick-recovery of patient, reduces the pain of patient.The curvature and the song of backbone of described arc rod 1
Rate is equal.
The section of described arc rod 1 is circle.A diameter of 0.4 ~ 0.6 micron of described micropore.
The course of work of the present invention is as follows：Arc rod 1 is first passed through to the other joint 6 of spinal joint 3, then makes inferior pyramidal head
5 wedgings are in basin bone 7, while making the wedging of epicone forming head 4 in the other joint 6 of top, micropore can increase conical head and bone
The bio-intermiscibility of bone, improves adhesion, the threaded portion of main screw 2 is screwed into spinal joint 3, finally realize arc
The upper and lower end parts of shape rod are fixedly secured, even if arc rod is hit by the external world, be also not easy to release, it is to avoid cause it is secondary by
Wound, reduces patient suffering.
Claims (3)
