A device for bending a kirschner wire comprises: a retaining slot for fixing a kirschner wire, with a contact for applying a bending force to a steel needle fixed by the retaining slot being disposed at a lateral of the retaining slot. Compared with the prior art in which clamping heads are used to clamp a steel needle first and then the steel needle is forcibly bent in the clamped state in most cases, which may be time-consuming and strenuous, the present invention provides not only a device for bending and chipping off an orthopedic steel needle in one time, which is applicable to cases where chipping off of steel needles is required, but also a device capable of only bending a steel needle, which is low in requirement on material and low in manufacturing cost as the force for bending a steel needle is far smaller than the force for chipping off the same, and thus is applicable to cases where only bending of steel needles is required.
