Description
Technical field
The invention belongs to technical field of medical instruments, it is related to a kind of orthopaedics band cap lock screw.
Background technology
The bone screw often used in bone surgery at present, bone screw is usually used in making bone tie again after the fracture
Close, Post operation bone screw need to generally retain a period of time up to bone length is good in human body, be needed necessarily during bone growth
Healing space, and traditional bone screw cortical layer of its screw thread and bone when being implanted into bone is mutually locked with cancellous bone layer, no
Beneficial to the growth of bone, final healing effect is influenceed.If avulsion bone piece is smaller or local comminuted fracture, screw fixes effect
Fruit is not good, the effect of influence bone growth healing, and burden is easily caused in physiology and psychologically to patient, and to family also band
Heavy financial burden is carried out.
The content of the invention
To achieve the above object, the present invention provides a kind of orthopaedics band cap lock screw, solves screw in the prior art
There is no union space, broken bone can not be fixed or comminuted fracture, influence bone are the problem of heal.
The technical solution adopted in the present invention is that a kind of orthopaedics is used with cap lock screw, including screw rod, the screw tip
Nut and pad are disposed with, the screw rod includes setting on the polished rod portion of upper end and the threaded portion of lower end, the threaded portion
There is screw thread, the threaded portion diameter is more than light gauge diameter, and the threaded portion end is provided with self tapping end, the self tapping end and spiral shell
Line portion end contact position surrounding is provided with multiple hook parts.
It is of the invention to be further characterized in that,
Further, it is provided with the nut and is disposed with concentric the first groove and the second groove from outside to inside,
First groove is equilateral triangle, and second groove is square.
Further, second groove is located at the bottom of the first groove.
Further, the hook part is memorial alloy.
Further, the helical angle of the screw thread is 30 °.
Further, the polished rod portion and flighted length ratio are 1:2.
The beneficial effects of the invention are as follows be provided with polished rod portion and threaded portion, can be swung during screw rod fixing bone, to leave
The space of bone healing, facilitates bone growth to heal；It is provided with the hook part of shaping, it is adaptable to fixed broken bone or comminuted bone
Folding, flexibility and direction can be adjusted as needed, to reach more preferable locking effect, promote bone healing；On nut just
The groove of triangle first, the regular hexagon structure that compares more is stablized, and the intensity of the screw of Triangle ID structure is more than interior hexagonal
Intensity, medical worker can use positive triangle instrument corresponding with interior positive triangular screw, screw can be fastened and unloaded.
Reduce the probability that Medical orthopedic screw easily grinds off interior side.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
There is the accompanying drawing used required in technology description to be briefly described, it should be apparent that, drawings in the following description are only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, can be with
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is structural representation of a kind of orthopaedics with cap lock screw of the invention.
Fig. 2 is a kind of nut structure schematic diagram of the orthopaedics of the invention with cap lock screw.
In figure, 1. polished rod portions, 2. nuts, 3. pads, 4. threaded portions, 5. screw threads, 6. hook parts, 7. self tapping ends；
21. the first groove, 22. second grooves.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
A kind of orthopaedics of present invention band cap lock screw, as depicted in figs. 1 and 2, including screw rod, the screw tip is successively
Nut 2 and pad 3 are provided with, the screw rod includes setting on the polished rod portion 1 of upper end and the threaded portion 4 of lower end, the threaded portion 4
There is screw thread 5, the diameter of threaded portion 4 is more than the diameter of polished rod portion 1, and the end of threaded portion 4 is provided with self tapping end 7, the self tapping
End 7 is provided with multiple hook parts 6 with the end contact position surrounding of threaded portion 4.
It is provided with the nut 2 and is disposed with concentric the first groove 21 and the second groove 22 from outside to inside, it is described
First groove 21 is equilateral triangle, and second groove 22 is square.Second groove 22 is located at the bottom of the first groove 21
Portion.The hook part 6 is memorial alloy.The helical angle of the screw thread 5 is 30 °.The length ratio of polished rod portion 1 and threaded portion 4 is
1:2。
A kind of orthopaedics of present invention band cap lock screw, when implantation is fixed, first becomes it hook part 6 by steeping frozen water
It is soft, so as to convenient moulding according to the fixed direction needed and flexibility progress.It will be locked in screw placement bone so that bone
Recombined at head rupture, in polished rod portion 1 and the injection bone of threaded portion 4, the locking of self tapping end 7 bone, threaded portion 4 passes through screw thread 5
Fixation is closely locked with bone, because the diameter of threaded portion 4 is more than the diameter of polished rod portion 1 and the outer wall of polished rod portion 1 is smooth, so that polished rod portion
1 is non-locking with bone, leaves the space with suitable union.Hook part 6 is stuck in broken bone to be fixed as needed after softening
After being waited 1 minute under place, normal temperature, hook part 6 is now sequentially sleeved in pad 3 and nut 2 on screw rod simultaneously by the moulding shape solidification of institute
It is screwed with instrument, the broken bone piece to be fixed of the locking of hook part 6, so as to reach the purpose of fixed bone piece.
First groove 21 uses equilateral triangle, and the regular hexagon structure that compares more is stablized, the screw of Triangle ID structure
Intensity is more than the intensity of interior hexagonal, and medical worker can use positive triangle instrument corresponding with interior positive triangular screw, can be to spiral shell
Nail is fastened and unloaded.Reduce the probability that Medical orthopedic screw easily grinds off interior side.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the scope of the present invention.It is all
Any modification, equivalent substitution and improvements made within the spirit and principles in the present invention etc., are all contained in protection scope of the present invention
It is interior.
