Description
Technical field
It is specially that a kind of cervical vertebra that is used for partly opens the door fixed in adjustable titanium plate fill the present invention relates to field of medical technology
Put.
Background technology
Cervical spondylopathy is a kind of present age common disease, generally requires to carry out operative treatment, but at present after the cervical vertebra of main flow
It is to reach operation purpose and effect by the way that vertebral plate opening is played reduction canalis spinalis pressure that road canalis spinalis, which expands shaping single open-door operation, so
And the vertebral plate that present inner fixing device is frequently resulted in after opening the door is closed the door again, the expansion shaping of canalis spinalis opens the door decompression with regard to nothing
Method is properly completed, and is severely impacted the effect of operation.And existing inner fixing device is often for the angle of enabling
Constant, the angle for enabling is selected merely by the subjective experience of patient, so can only make in surgical procedure
With the titanium plate of fixed angle, this is likely to occur open angle not enough during resulting in use, and the effect that influence canalis spinalis opens the door allows
The decompression of canalis spinalis can not obtain promising result, and can not be adjusted during operation installation, it is impossible to press close to vertebral plate well and be fixed, lead
Cause the loosening of inner fixing device.
The content of the invention
Partly opened the door adjustable titanium plate inner fixing device for cervical vertebra it is an object of the invention to provide a kind of, possess length
The advantage of adjustable and angle adjustable, solves the enabling titanium plate inner fixing device length of cervical vertebra half, angle in the prior art
The problem of can not adjusting.
To achieve the above object, the present invention provides following technical scheme：It is a kind of partly to be opened the door adjustable titanium plate for cervical vertebra
Inner fixing device, including the first installation sheet, titanium nail stator and the first titanium plate, first installation sheet and the centrum side on cervical vertebra
Block is fixedly connected, and the first titanium nail mounting hole is provided with the middle part of the first installation sheet, and the side for following closely mounting hole in the first titanium is installed
There is titanium to follow closely stator, the two bottom sides of the first installation sheet are provided with the first journal stirrup and the second journal stirrup, set in the middle part of the first journal stirrup
Screw is equipped with, in the screwed hole that is internally provided with of the second journal stirrup, the first installation sheet is lived by screw and screwed hole and the first titanium plate
Telescopic Fixed hole is provided with dynamic connection, first titanium plate, the second titanium plate is installed in one end of the first titanium plate, in the second titanium
Telescopic head is provided with the top of plate, spring is installed in the bottom of telescopic head, the first titanium plate and the second titanium plate pass through Telescopic Fixed
Hole and telescopic head are flexibly connected, and are flexibly connected in the bottom of the second titanium plate by screw and screwed hole with the second installation sheet, the
Be provided with the middle part of two installation sheets the second titanium nail mounting hole, the second titanium nail mounting hole inside be provided with titanium follow closely the second installation sheet with
Cervical vertebra plate on cervical vertebra is fixedly connected.
It is preferred that, first installation sheet and the second installation sheet by the first titanium follow closely mounting hole, the second titanium follow closely mounting hole and
Vertebral plate of the titanium nail respectively with centrum lateral mass and centrum is fixedly connected.
It is preferred that, the screw is a kind of component of titanium material.
It is preferred that, the titanium nail stator is rotatable.
Compared with prior art, beneficial effects of the present invention are as follows：The present invention is installed in the side that the first titanium follows closely mounting hole
There is titanium to follow closely stator, titanium nail stator is rotatable, it is rotated after, titanium nail stator can cover titanium nail, it is to avoid titanium nail is de-
Fall, make the even closer of titanium nail fixation, the first installation sheet is flexibly connected by screw and screwed hole with the first titanium plate, passes through rotation
Screw makes the connection angle of the first titanium plate and the first installation sheet produce change, and this can better adapt to posterior cervical canalis spinalis and be expanded into
The angle and compactness of type single open-door, the second titanium plate are slightly less than the first titanium plate, therefore the second titanium plate may be inserted into the first titanium plate
Portion, insertion depth can be adjusted, and telescopic head, telescopic head size and Telescopic Fixed hole size phase are provided with the top of the second titanium plate
Together, spring is installed in the bottom of telescopic head, telescopic head can be made elastic, the first titanium plate and the second titanium plate pass through flexible consolidate
Determine hole and telescopic head to be flexibly connected, the first titanium plate and the second titanium plate is obtained pattern length and can adjust, it is possible to by telescopic head and
Telescopic Fixed hole regular length, whole device adjustable in length, angle adjustable can better adapt to the expansion of posterior cervical canalis spinalis
The length and angle of big shaping single open-door, thus be avoided that carried out in surgical procedure the measuring of inside-fixture, moulding, selection and
Waste the substantial amounts of operation quality time, it is not necessary to which the device of every kind of model is all produced.
