Description
Technical field
The present invention relates to the technical field of backbone solid state support, particularly a kind of spine fixator.
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 angle for the patient of different age group between spinal joint is different, using common spiral shell
Nail is only oblique to be screwed into spinal joint, and screw is in angle with spinal joint face, therefore is difficult to be screwed into spinal joint, time-consuming to take
Power, and connect also not firm enough, return the pain that patient brings.Further, since spinal joint original structure was impacted, should
Increase at power concentration, bone strength certainly will decline, it is necessary to take a long time recovery, the defect that there is 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, connection is firm
Gu, save be screwed into power, the spine fixator suitable for different age group patient.
The purpose of the present invention is achieved through the following technical solutions：A kind of spine fixator, it includes retainer body, ball
Upper cavity and lower chamber are offered in head and main screw, the retainer body, lower chamber is connected with upper cavity, is set in lower chamber
It is equipped with fixed seat, fixed seat and offers spherical cavity, the bulb coordinated with it is installed in spherical cavity, bulb internal thread connects
Main screw is connected to, main screw head is upwardly extended outside bulb, and the end of thread of main screw is extended downwardly in outside retainer body
The runner for connecting main screw upper and lower end parts is offered in portion, main screw, described upper cavity is provided with briquetting, and the bottom of briquetting is set
Sleeve is equipped with, sleeve is placed on the joint for being provided with and being plugged in runner in main screw head, sleeve, and the other end of joint is fixed on
The feed pathway of connection joint is offered in briquetting bottom, briquetting, the left and right sides of described retainer body is respectively connected with time spiral shell
Nail, secondary screw is pressed on briquetting.
Secondary screw described in two is symmetrical arranged.
The tapered shape in bottom of described joint.
Described retainer body is column.
The bottom of described retainer body offers through hole.
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. 1 is structural representation of the invention；
Fig. 2 is the schematic diagram of the screw anglec of rotation；
In figure, 1- retainer bodies, 2- bulbs, the main screws of 3-, 4- fixed seats, 5- runners, 6- briquettings, 7- sleeves, 8- joints, 9-
Feed pathway, 10- screw.
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 the figures 1 and 2, a kind of spine fixator, it includes retainer body 1, bulb 2 and main screw 3, the fixator sheet
Body 1 is to offer upper cavity and lower chamber in column, retainer body 1, and lower chamber is connected with upper cavity, is provided with lower chamber
The bulb 2 for being provided with and coordinating with it in spherical cavity, spherical cavity is offered in fixed seat 4, fixed seat 4, bulb 2 can be spherical
Rotated in cavity, the internal thread of bulb 2 is connected with main screw 3, and the main head of screw 3 is upwardly extended outside bulb 2, main screw 3
The end of thread is extended downwardly outside retainer body 1, and the runner 5 for connecting the main upper and lower end parts of screw 3, institute are offered in main screw 3
The upper cavity stated is provided with briquetting 6, and the bottom of briquetting 6 is provided with sleeve 7, and sleeve 7 is placed in the main head of screw 3, sleeve 7 and set
There is the joint 8 being plugged in runner 5, the tapered shape in bottom of joint 8, the other end of joint 8 is fixed on the bottom of briquetting 6, press
The feed pathway 9 of connection joint 8 is offered in block 6, the left and right sides of described retainer body 1 is respectively connected with time screw 10, secondary
Screw 10 is pressed on briquetting 6, and the secondary screw 10 described in two is symmetrical arranged.The bottom of described retainer body 1 is offered
Through hole.
The course of work of the present invention is as follows：If angle is 180 degree between the spinal joint face of patient, first make main screw 3
It is vertical to be screwed into spinal joint, as shown in figure 1, sleeve 7 is placed on into the main head of screw 3 again, puts and move down dynamic pressure block 6 backward, connect
First 8 are just inserted in runner 5, then tighten two screws 10, it is ensured that two times briquetting 6 is fixed on upper cavity by screw 10
It is interior, realize the installation of the fixator, add calcium fluoride melt solution in most backward feed pathway 9, solution sequentially through feed pathway 9,
Joint 8 and runner 5 enter in spinal joint, and calcium fluoride melt solution can increase the intensity of bone, supplement bone calcium constituent, accelerate
The recovery of patient.
If between the spinal joint face of patient angle be less than 180 degree, first make rotation bulb 2 make main screw 3 be adjusted to
Spinal joint face is vertical, as shown in Fig. 2 the angle of the adjustment bottom face of briquetting 6 is so that sleeve 7 is placed on the main head of screw 3, after putting
Briquetting 6 is moved down, joint 8 is just inserted in runner 5, finally tighten two screws 10, it is ensured that two times screw 10 will
Briquetting 6 is fixed in upper cavity, realizes the installation of the fixator.
