Description

Simple Kirschner wire bending and placing device

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to simple and easy kirschner wire is bent and placer.

Background

The kirschner wire is a commonly used internal fixation material for orthopedics, is used for fixing short fracture, avulsion fracture and other fracture with low stress, and is also used for fixing temporary fracture blocks in orthopedic surgery. The Kirschner wire is widely applied in orthopedic surgery and has the advantages of convenient use, small wound and low price. The kirschner wire can fix the fracture of short ossicle, such as metacarpal bone, metatarsal bone, phalanx and the like. Common avulsion fracture or tension fracture is often fixed by using a tension band composed of a kirschner wire and a steel wire. Meanwhile, in an orthopedic operation, for complicated fractures with serious crushing, such as calcaneal fracture, tibial plateau fracture and the like, the kirschner wire can assist the steel plate to fix.

At present, orthopedic instruments such as a needle holder and a vascular clamp are used for clamping a kirschner wire to be manually bent and placed clinically. One of the two methods is inconvenient to operate, not in place to bend, easy to slip when placed, and capable of causing secondary damage to patients due to the fact that multiple operations are needed. Secondly, the destruction of the orthopaedic instrument.

Disclosure of Invention

The utility model discloses there are operating stability poor and inefficiency not enough among the main prior art of solution, provide a simple and easy kirschner wire and bend and placer, it has simple structure, operating stability is good and efficient characteristics.

Detailed Description

The technical solution of the present invention is further specifically described below by way of embodiments and with reference to the accompanying drawings.

The embodiment is as follows: as shown in fig. 1-4, a simple kirschner wire bending and placing device comprises an operating rod 3, a knocking ring 1 communicated with the operating rod 3 is arranged at the upper end of the operating rod 3, a handle 2 is arranged between the knocking ring 1 and the operating rod 3, the handle 2 and the operating rod 3 are both of a hollow structure, and an arc-shaped opening 4 is formed in the outlet end of the operating rod 3. The operating rod 3 is composed of a split structure of a connecting rod 5 and a bending rod 6. The inner side of the lower end of the connecting rod 5 is provided with an internal thread 7, and the outer side of the upper end of the bending rod 6 is provided with an external thread 8 which is in threaded sleeve joint with the internal thread 7.

The bending and placing device is of a hollow structure, and the Kirschner wire is sheathed in the bending and placing device and is bent manually. The tail part of the bent kirschner wire is buckled by the arc-shaped opening 4, so that the proper direction can be adjusted. And finally, lightly knocking the knocking ring 1 at the tail part by a hammer to drive the tail part of the Kirschner wire into the tail part to be tightly attached to the bone surface.

To sum up, this simple and easy kirschner wire bends and placer has simple structure, operating stability is good and efficient characteristics. The problem of bend and place the kirschner wire is solved. The orthopedic instrument is prevented from being damaged due to improper operation when the orthopedic instrument is used for treating the Kirschner wire.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without deviating from the basic characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
