Abstract
The invention discloses an internal fixing Kirschner wire for fracture. The Kirschner wire can prevent the rear shaft of the Kirschner wire from retreating, and can also prevent the Kirschner wire from excessively inserting into human body tissues in an axial direction. The internal fixing Kirschner wire for fracture comprises a needle bar and a needle point arranged at the head part of the needle bar, wherein the needle point is in self-tapping needle head design, the needle bar is provided with a limiting part with a threading hole, the lateral size of the limiting part is larger than the diameter of the needle bar, and the tail end of the needle bar is in a triangular prism shape.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, be meant that especially a kind of fracture internal fixation uses Kirschner wire.
Background technology
Kirschner wire is a kind of orthopaedics internal fixation material commonly used, and generally about 20 centimeters, diameter has several kinds of different specifications to its former specification between the 0.5-2 millimeter.Be used for fixing short and small fracture or the little fracture fixation of avulsion fracture iso-stress, also often be used in the bone surgery in interim sclerite fixing.Along with the extensive use of exterior fixation bracket, the maximum gauge of Kirschner wire once was added to 4 millimeters gradually in recent years, cooperated the external fixation pinning to fix emergent bigger fracture such as fracture of pelvis, fracture of calcaneus.After Kirschner wire was squeezed into skeleton, a period of time Kirschner wire can occur and retreat phenomenon, found that through analyzing Kirschner wire does not have screw thread, just inserted in the skeleton, had no hold.Used steel wire just has certain force of strain to skeleton, and pressurization also has no stress point on Kirschner wire, so the phenomenon that just has the Kirschner wire postoperative to retreat takes place.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of Kirschner wire postoperative that can prevent axially to retreat, can prevent that again the fracture internal fixation in the axially undue insertion tissue of Kirschner wire from using Kirschner wire.
For solving the problems of the technologies described above; Technical scheme of the present invention is: a kind of fracture internal fixation is used Kirschner wire; Comprise shank and the needle point that is arranged on the shank head, said needle point is the design of self tapping ailhead, and said shank is provided with the limiting section of band through wires hole; The lateral dimension of said limiting section is greater than the diameter of shank, and the tail end of said shank is arranged to triangular prism shaped.
As a kind of preferred scheme, said limiting section is near the shank afterbody and be positioned at 1/4th places of shank.
As a kind of preferred scheme, said shank is provided with graduation mark.
After having adopted technique scheme, effect of the present invention is: because said fracture internal fixation is used Kirschner wire, comprise shank and the needle point that is arranged on the shank head; Said needle point is the design of self tapping ailhead, and said shank is provided with the limiting section of band through wires hole, and the lateral dimension of said limiting section is greater than the diameter of shank; The tail end of said shank is arranged to triangular prism shaped, and therefore, at first the steel wire in operation can penetrate through through wires hole; Like this, steel wire has certain reinforcement effect to Kirschner wire, thus the phenomenon of avoiding the postoperative Kirschner wire to retreat; And the lateral dimension of limiting section is greater than the diameter of shank; Like this, when Kirschner wire inserts, the spacing of limiting section just arranged, thereby preventing that Kirschner wire is undue is inserted in the tissue.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is the structural representation of the embodiment of the invention;
In the accompanying drawing: 1. shank; 2. needle point; 3. limiting section; 4. through wires hole; 5. triangular prism shaped.
The specific embodiment
Through specific embodiment the present invention is made further detailed description below.
A kind of fracture internal fixation is used Kirschner wire, and is as shown in Figure 1, and it comprises shank 1 and the needle point 2 that is arranged on shank 1 head, and said needle point 2 is the design of self tapping ailhead; Said shank 1 is provided with the limiting section 3 of band through wires hole 4, and the lateral dimension of said limiting section 3 is greater than the diameter of shank 1, and through wires hole 4 can be a circular hole, also can be strip hole; Said limiting section 3 is a near round shape, certainly, also can be other shape; Like rhombus, square or other irregular shapes, as long as the lateral dimension of limiting section 3 is greater than the diameter of shank 1, like this; After Kirschner wire inserts, the spacing of limiting section 3 arranged, thereby can prevent that Kirschner wire too is inserted in the tissue.It is to be convenient to be connected with implanting instrument that the tail end of said shank 1 is arranged to triangular prism shaped 5, triangular prism shaped 5, makes things convenient for Kirschner wire to be implanted in the skeleton, and implanting instrument can be an electric drill.Said limiting section 3 is near shank 1 afterbody and be positioned at 1/4th places of shank 1.Said shank 1 is provided with graduation mark.Be convenient to observe the degree of depth of implantation like this.
Claims (3)
1. the fracture internal fixation is used Kirschner wire; Comprise shank and the needle point that is arranged on the shank head; It is characterized in that: said needle point is the design of self tapping ailhead; Said shank is provided with the limiting section of band through wires hole, and the lateral dimension of said limiting section is greater than the diameter of shank, and the tail end of said shank is set as triangular prism shaped.
2. fracture internal fixation as claimed in claim 1 is used Kirschner wire, it is characterized in that: said limiting section is near the shank afterbody and be positioned at 1/4th places of shank.
3. fracture internal fixation as claimed in claim 2 is used Kirschner wire, it is characterized in that: said shank is provided with graduation mark.
