Abstract
The invention belongs to the technical field of medical equipment and particularly relates to an immobilized pedicle screw. The immobilized pedicle screw comprises a thread rod with an external thread and a self-tapping tip, the self-tapping tip is provided with a groove, and the other end of the thread rod is connected with a clamping support portion. The other end of the clamping support portion is connected with a first stud, the other end of the first stud is connected with a second stud identical to the first stud in diameter, and a joint surface of the first stud and the second stud is provided with a triangular groove. The immobilized pedicle screw has the advantages that fixation can be realized conveniently by cooperation of nuts after implantation of the pedicle screw, angular regulation is realized by the aid of an angle connection rod, and more humanized selections are provided for operations.
Description
Technical field
The invention belongs to technical field of medical instruments, be specifically related to a kind of fixing pedicle screw.
Background technology
Pedicle screw, as a kind of spinal surgery device of maturation, is widely used.Current pedicle nail mainly offshore company is developed and is released in market, and it all adopts hollow pedicle to follow closely, and preset length and the radian of rod, device design is loaded down with trivial details, and processing technology difficulty is large; The pedicle screw-rod fixed system of domestic employing, substantially divide two large classes, a class is still similar to external pedicle screw, adopts the design of hollow pedicle nail, presets excellent length and radian, there is above-mentioned identical defect; The non-hollow Pediculus arcus vertebrae screw of another kind of application, but using the locating effect that cannot reach hollow pedicle nail in this non-hollow Pediculus arcus vertebrae screw process, and Pedicle Screw position is difficult to accurate control.
Summary of the invention
The object of the invention is to solve above-mentioned technical problem and provide a kind of structure simple and handled easily to ensure that putting nail position fixes pedicle screw accurately.
For achieving the above object, the present invention adopts following technical scheme:
A kind of fixing pedicle screw, comprise and there is externally threaded threaded rod, described threaded rod has the reeded self-taped type termination of band, the other end of described threaded rod is equipped with a Kato portion, the other end in described Kato portion is equipped with the first spiro column, the described first spiro column other end is equipped with the second mutually identical spiro column of diameter, and the link position mask of described first spiro column, the second spiro column has triangle groove.
Improve as one, described Kato portion is connected by arc-shaped transition with described threaded rod, and the joint face of described Kato portion and described first spiro column is plane, and the external margin in described Kato portion is regular polygon structure.
The present invention fixes pedicle screw, owing to having externally threaded threaded rod, described threaded rod has the reeded self-taped type termination of band, the other end of described threaded rod is equipped with a Kato portion, the other end in described Kato portion is equipped with the first spiro column, the described first spiro column other end is equipped with the second mutually identical spiro column of diameter, described first spiro column, the link position mask of the second spiro column has triangle groove, fixed by nut screw connection after can conveniently implanting, and carry out angle adjustment by angle connecting rod, the more hommization of operation technique can be given select.
Accompanying drawing explanation
Figure 1 shows that the structural representation of a kind of fixing pedicle screw that the embodiment of the present invention provides;
Figure 2 shows that the side view under another visual angle of Fig. 1.
Detailed description of the invention
Below, in conjunction with example, substantive distinguishing features of the present invention and advantage are further described, but the present invention is not limited to listed embodiment.
Shown in Fig. 1,2, the figure shows the structure of a kind of fixing pedicle screw that the embodiment of the present invention provides.For convenience of explanation, illustrate only the part relevant with the embodiment of the present invention.
Refer to Fig. 1,2, a kind of fixing pedicle screw, comprise and there is externally threaded threaded rod 1, described threaded rod 1 has the self-taped type termination 3 of band fluted 2, the other end of described threaded rod 1 is equipped with a Kato portion 4, the other end in described Kato portion 4 is equipped with the first spiro column 5, and described first spiro column 5 other end is equipped with the second mutually identical spiro column 6 of diameter, and the link position mask of described first spiro column 5, second spiro column 6 has triangle groove 7.
Improve as one, described Kato portion 4 is connected by arc-shaped transition with described threaded rod 1, and described Kato portion 2 is plane with the joint face of described first spiro column 5, and the external margin in described Kato portion 5 is regular polygon structure.
Improve as one, the free end of described second spiro column 6 has a word straight trough 8.
The present invention fixes pedicle screw, owing to having externally threaded threaded rod, described threaded rod has the reeded self-taped type termination of band, the other end of described threaded rod is equipped with a Kato portion, the other end in described Kato portion is equipped with the first spiro column, the described first spiro column other end is equipped with the second mutually identical spiro column of diameter, described first spiro column, the link position mask of the second spiro column has triangle groove, fixed by nut screw connection after can conveniently implanting, and carry out angle adjustment by angle connecting rod, the more hommization of operation technique can be given select.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the premise without departing from the principles of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
