Abstract
The utility model relates to a kind of new type bone steel needles, including ontology, the ontology include it is sequentially connected enter osseous part, threaded portion, connecting rod, it is described enter osseous part, threaded portion, connecting rod be integrally formed, the recess that fractures is equipped between the threaded portion and connecting rod, the free end of the connecting rod is equipped with the clamping portion for being clamped with external impetus equipment.Which solve existing bone steel needles as when being fixed temporarily effect the problem of being not easy to lock, be not easily broken, be not easily taken out.
Description
Technical field
The utility model relates to a kind of new type bone steel needles.
Background technique
China Patent No.: CN201110208679.X discloses one kind and can prevent the postoperative axial retrogressing of Kirschner wire and prevent
The only Kirschner wire for internal fixation of fracture in the axial excessively insertion tissue of Kirschner wire.The Kirschner wire for internal fixation of fracture, including
Shank and the needle point that shank head is arranged in, the needle point are the design of self tapping ailhead, and the shank is equipped with the limit with threading hole
Position portion, the lateral dimension of the limiting section are greater than the diameter of shank, and the tail end of the shank is arranged to triangular prism shaped.The patent is public
The G-needle opened facilitate locking and exit, but sometimes, in certain surgical procedures, when bone steel needle merely as
When being fixed temporarily effect, too short bone steel needle is unfavorable for locking operation, after being locked using long bone steel needle, next bone steel
Needle is easy to be not easy to operate because of the presence of upper bone steel needle, and after the completion of operation, bone steel needle is fixed temporarily effect
It eliminates, just needs this when to be drawn off.Therefore, a kind of new bone steel needle is needed this when just to solve these problems.
Utility model content
Therefore, for above-mentioned problem, the utility model proposes a kind of structures simply, is easily locked, is easy to fracture, being easy to
The new type bone steel needle of taking-up.Which solve existing bone steel needles as being not easy to lock, be not easily broken, be not easy when being fixed temporarily effect
The problem of taking-up.
To achieve the above object, the utility model uses following technical scheme: a kind of new type bone steel needle, including ontology,
The ontology include it is sequentially connected enter osseous part, threaded portion, connecting rod, it is described enter osseous part, threaded portion, connecting rod be integrally formed,
Be equipped with and fracture recess between the threaded portion and connecting rod, the free end of the connecting rod equipped with for external impetus equipment
The clamping portion of clamping.
Further, it is described enter osseous part diameter be less than threaded portion diameter, it is described to enter to connect between osseous part and threaded portion
Equipped with transition part.
Further, the clamping portion is cylindric or outer hexagonal or interior hexagonal.
By using preceding solution, the beneficial effects of the utility model are: the utility model bone steel needle passes through clamping portion energy
Enough realize is easily locked, and can be realized by the setting recess that fractures and is easy to fracture, so that the length of bone steel needle is easily locked,
Length can be satisfied after fractureing, obstacle will not be formed to the operation of rear symplectic bone steel needle, and there is after fractureing spiral shell on bone steel needle
Line portion, when be fixed temporarily effect eliminate after, can be socketed on threaded portion by external withdrawing device, thus realize conveniently,
Quickly take out bone steel needle；Further, it is described enter osseous part diameter be less than threaded portion diameter, it is described enter osseous part and threaded portion
Between be connected with transition part, the rigidity that both the setting of transition part can better ensure that.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Now in conjunction with the drawings and specific embodiments, the present invention will be further described.
With reference to Fig. 1, the present embodiment provides a kind of new type bone steel needle, including ontology, the ontology include it is sequentially connected enter
Osseous part 1, threaded portion 2, interconnecting piece 3, it is described enter osseous part 1, threaded portion 2, interconnecting piece 3 be integrally formed, the threaded portion 2 and interconnecting piece
The recess 4 that fractures is equipped between 3, the free end of the connecting rod 3 is equipped with the clamping portion 31 for being clamped with external impetus equipment.
It is described enter osseous part 1 diameter be less than threaded portion 2 diameter, it is described to enter to be connected with transition part 5 between osseous part 1 and threaded portion 2.Institute
It is cylindric for stating clamping portion 31, or outer hexagonal is interior hexagonal, and the outer surface of the clamping portion 31 is rough surface.
The working method of the utility model bone steel needle are as follows: external tool sandwiched clamping portion is utilized, it will to the marrow by way of drilling
Portion is embedded in bone, and threaded portion, interconnecting piece are exposed to outer at this time, then, using external tool for breaking off by threaded portion, interconnecting piece
From fractureing, recess fractures, and can then carry out the locking operation of another bone steel needle, so repeats.When the effect of being fixed temporarily is eliminated
Afterwards, it is sheathed on threaded portion using external tool, osseous part will be entered and taken out from bone, so repeated, complete operation.
The utility model bone steel needle can be realized by clamping portion to be easily locked, and be can be realized by the setting recess that fractures and is easy to roll over
It is disconnected, so that the length of bone steel needle is easily locked, length can be satisfied after fractureing, it will not be to the operation shape of rear symplectic bone steel needle
At obstacle, and there is threaded portion after fractureing on bone steel needle, after the effect of being fixed temporarily is eliminated, can be filled by external taking-up
It sets and is socketed on threaded portion, quickly and easily take out bone steel needle to realize；Further, it is described enter osseous part diameter be less than
The diameter of threaded portion, described to enter to be connected with transition part between osseous part and threaded portion, the setting of transition part can better ensure that
The rigidity of the two.
Although specifically showing and describing the utility model in conjunction with preferred embodiment, those skilled in the art is answered
This is understood, in the spirit and scope for not departing from the utility model defined by the appended claims, in form and details
On the utility model can be made a variety of changes, be the protection scope of the utility model.
