The invention belongs to technical field of medical instruments, it is specifically related to a kind of pedicle screw system angle regulator, including a body of rod, the described body of rod there is the first bar portion and the second bar portion, described first bar portion is connected by arc-shaped transition bar portion with described second bar portion, and described second bar portion is provided with the angle adjustment holes for being connected with pedicle screw.Pedicle screw system angle regulator of the present invention, including a body of rod, the described body of rod there is the first bar portion and the second bar portion, described first bar portion is connected by arc-shaped transition bar portion with described second bar portion, described second bar portion is provided with the angle adjustment holes for being connected with pedicle screw, after can being connected with pedicle screw by this angle adjustment holes, the convenient implant angle to pedicle screw is fixed after being adjusted again, give operator the most more to select, solve the technical problem that a kind of angle pedicle screw does not adapt to the needs of different patient.
Description
Technical field
The invention belongs to technical field of medical instruments, be specifically related to a kind of pedicle screw system angle and adjust
Regulating device.
Background technology
Pedicle screw, as the spinal surgery device of a kind of maturation, is widely used.Vertebral arch at present
Root nail mainly offshore company develops and releases in market, and it all uses hollow pedicle to follow closely, and presets rod
Length and radian.The pedicle screw-rod fixed system of domestic employing, substantially divides two big classes, a class still with state
Outer pedicle screw is similar, uses hollow pedicle nail design, presets rod length and radian, another kind of should
Use non-hollow Pediculus arcus vertebrae screw, determine put nail position after, in order to fix after pedicle screw, generally
Corresponding attachment means is used to be coupled together by screw, it is ensured that effect, but current attachment means structure merit
Can be single, this screw can only be implanted in a kind of angle, it is impossible to nail position is put in the personalization adapting to different patient
The needs of angle.
Summary of the invention
It is an object of the invention to solve above-mentioned technical problem and provide a kind of pedicle screw system to use
Angle regulator.
For achieving the above object, the present invention adopts the following technical scheme that
A kind of pedicle screw system angle regulator, including a body of rod, having of the described body of rod
First bar portion and the second bar portion, described first bar portion and described second bar portion are by arc-shaped transition bar portion phase
Connecting, described second bar portion is provided with the angle adjustment holes for being connected with pedicle screw.
Described angle adjustment holes includes a circular port, and the upper end of circular port connects a flared aperture, described enlarging
The hole wall in hole is arcwall face structure.
The two ends of the described body of rod are smooth globoidal structure.
Pedicle screw system angle regulator of the present invention, including a body of rod, the tool of the described body of rod
Having the first bar portion and the second bar portion, described first bar portion and described second bar portion are by arc-shaped transition bar portion
Being connected, described second bar portion is provided with the angle adjustment holes for being connected with pedicle screw, permissible
After being connected with pedicle screw by this angle adjustment holes, the convenient implant angle to pedicle screw is carried out
Fix again after regulation, give operator and the most more select, solve only a kind of angle and implant
Screw does not adapt to the technical problem of the needs of different patient.
Accompanying drawing explanation
Fig. 1 show a kind of pedicle screw system angle regulator of embodiment of the present invention offer
Structural representation；
Fig. 2 show the schematic top plan view of Fig. 1.
Detailed description of the invention
Below, in conjunction with example, substantive distinguishing features and the advantage of the present invention are further described, but this
Bright it is not limited to listed embodiment.
See Fig. 1, shown in 2, the figure shows a kind of pedicle screw system that the embodiment of the present invention provides
The structure of system angle regulator.For convenience of description, illustrate only relevant with the embodiment of the present invention
Part.
Refer to Fig. 1 and 2, a kind of pedicle screw system angle regulator, including a body of rod,
The described body of rod there is the first bar portion 1 and the second bar portion 2, described first bar portion and described second bar
Portion is connected by arc-shaped transition bar portion 6, and described second bar portion is provided with for being connected with pedicle screw
The angle adjustment holes 3 connect.
Described angle adjustment holes includes a circular port 5, and the upper end of circular port connects a flared aperture 4, described
The hole wall of flared aperture is arcwall face structure.
The two ends 7,8 of the described body of rod are smooth globoidal structure.
Pedicle screw system angle regulator of the present invention, including a body of rod, the tool of the described body of rod
Having the first bar portion and the second bar portion, described first bar portion and described second bar portion are by arc-shaped transition bar portion
Being connected, described second bar portion is provided with the angle adjustment holes for being connected with pedicle screw, permissible
After being connected with pedicle screw by this angle adjustment holes, the convenient implant angle to pedicle screw is carried out
Fix again after regulation, give operator and the most more select, solve only a kind of angle and implant
Screw does not adapt to the technical problem of the needs of different patient.
The above is only the preferred embodiment of the present invention, it is noted that general for the art
For logical technical staff, under the premise without departing from the principles of the invention, it is also possible to make some improvement and profit
Decorations, these improvements and modifications also should be regarded as protection scope of the present invention.
