Abstract

The invention provides a sliding-preventing kirschner wire, applied to orthopedic clinics. The kirschner wire is composed of a wire point, a wire body and an expansion part, wherein the expansion part is a cylinder-shaped expansion part extending to the wire tail, or is a section of globoid-shaped or cylinder-shaped expansion part close to the wire tail, the diameter of the expansion part is greater than that of the wire body, the expansion part and the wire body can be in integral design, or the globoid-shaped or cylinder-shaped expansion part and the wire body can be in independent structures, the end, close to the wire point, of the cylinder-shaped expansion part can be provided with threads, and the wire tail can be provided with a plane. The sliding, loosing and separating of the kirschner wire can be effectively prevented, the infection of a nail channel can be reduced, and the fracture healing can be accelerated.

Description

Can the Kirschner wire of anti-sliding stop

Technical field

The present invention relates to a kind of medical apparatus and instruments of orthopedics clinic practice, particularly relate to a kind of can the Kirschner wire of anti-sliding stop.

Background technology

Kirschner wire individually or is used in combination with other orthopedic instrument, is widely used in Orthopedic Clinical, is used for fixing fractured bones, have simple to operate, The advantage such as flexibly, but there will be during using Kirschner wire loosen, abjection, the complication such as pin track infection, even fix unsuccessfully, sometimes have to Except fixing, reuse alternate manner and fix.People also devise multiple different Kirschner wire, but how reduce because of intensity or attachment device is the most multiple Miscellaneous, it is impossible to be applied to clinic very well.

Summary of the invention

It is an object of the invention to make up the defect that currently used Kirschner wire treatment fracture exists, it is provided that one have can anti-sliding stop, simple in construction, The reliable Kirschner wire of easy to operate, intensity, can effectively prevent Kirschner wire from sliding, loosen, deviate from, reducing pin track infection, accelerating bone healing.

Present invention employs following technical scheme:

A kind of orthopedics clinic practice can be anti-skidding Kirschner wire, be made up of needle point, needle body, enlargement.

Further, enlargement is to extend to the cylindric enlargement of backshank or for one section of cylindric enlargement of inclined backshank, enlargement Diameter is big compared with needle body diameter.

Further, enlargement is the spheroid enlargement of inclined backshank, and enlargement diameter is big compared with needle body diameter.

Further, enlargement is integrated with needle body designs, is maybe set to the structure mutually independent with needle body by expanding, with pin for suppressing metal or the shape of welding Enlargement is connected by formula with needle body.

Further, cylindric enlargement sets screw thread near one end of needle point, it is simple to enlargement is screwed into sclerotin, anti-upper Kirschner wire abjection, rotation.

Further, Aculeata sets an axial plane, it is simple to use when the threaded Kirschner wire of enlargement is screwed into.

Present invention firstly provides the Kirschner wire of a kind of improvement, have the beneficial effects that the following aspects:

First, the present invention devises the enlargement of Kirschner wire, when Kirschner wire and exterior fixation bracket or other device are with the use of, kirschner that can be anti-skidding When pin cross-reference is by the skeletal fixation of fracture site side, enlargement can effectively prevent the movement of skeleton, it is to avoid loosening of Kirschner wire occurs；

Secondly, as preferably design, cylindric enlargement can set screw thread near one end of needle point, it is simple to enlargement is screwed into sclerotin, prevents gram The abjection of family name's pin, rotation；

Again, as preferably design, Aculeata sets an axial plane, it is simple to use when the threaded Kirschner wire of enlargement is screwed into, processing ease.

To sum up, use the present invention can be anti-skidding Kirschner wire carry out fracture fixation, can effectively prevent the movement of skeleton, it is to avoid occur Kirschner wire slip, Loosen, deviate from, reduce pin track infection, accelerating bone healing.

Detailed description of the invention

Accompanying drawing below in conjunction with description carries out clear, complete description to the technical scheme in the embodiment of the present invention.

Can be made up of needle point 1, needle body 2, enlargement by anti-skidding Kirschner wire.

Enlargement is set to extend to the cylindric enlargement 3 of backshank, or is one section of cylindric enlargement 4 or spherical of inclined backshank in the middle part of needle body Body enlargement 5, enlargement and needle body may be designed as one, it is possible to the 5 or cylindric enlargement 4 that expanded by spheroid are set to mutually only with needle body Vertical structure, expands cylindric enlargement 4, spheroid with the form of pin for suppressing metal 6 or welding and 5 is connected with needle body 2, cylindric bulb Divide the one end near needle point 1 can set screw thread 7, it is simple to enlargement is screwed into sclerotin, prevent Kirschner wire abjection, rotate.Aculeata can set one and axially put down Face (8), it is simple to use when the Kirschner wire of enlargement threaded (7) is screwed into.

Fig. 1 is Kirschner wire I type structure that can be anti-skidding, is made up of needle point 1, needle body 2, enlargement 3, and enlargement 3 is the circle extending to backshank Column enlargement.

Fig. 2 is Kirschner wire II type structure that can be anti-skidding, needle point 1, needle body 2, cylinder expand and 4 form, and enlargement is the one of inclined backshank The cylindric enlargement of section.
