Kirschner wire clamp

Abstract

A Kirschner wire clamp is used to reliably and simply fix bone plates to a bone surface. The wire clamp consists of a tubular guide member for receiving a Kirschner wire. The guide member has a bore surrounded by a wall and a base for engaging a hole in a bone plate such as a bone screw hole. A spring clamp is mounted adjacent an open end of the tubular guide bore opposite the base which clamps the Kirschner wire to the guide member after the wire has been fixed in bone. The Kirschner wire clamp can be aligned simply and reliably by the guide member, and by the clamping mechanism, can be reliably fixed to the Kirschner wire.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of the filing date of German Utility Model Application No. 20 2008 000 914.6 filed Jan. 22, 2008.BACKGROUND OF THE INVENTION[0002]The present invention relates to a Kirschner wire clamp for positioning a bone plate, in particular a Kirschner wire clamp, which allows more precise, easier and simpler positioning of a bone plate on a bone surface.[0003]In the treatment of bone fractures it is helpful and sometimes necessary that, prior to fixation of a fracture by bone plates, the fracture itself is stabilized. This is, in particular, helpful or necessary in cases where the bone fracture not only comprises two fragments but a multitude of fragments. In this case it may be necessary to stabilize the multitude of fragments in their original position before fastening corresponding bone plates and bone screws for fixation of the fracture. Such stabilization and preliminary fixation are often achieved by so-cal...

AI Technical Summary

Benefits of technology

[0031]It should be noted that the individual features can of course also be combined, as a result of which, in part, advantageous effects may arise which exceed the sum of the individual effects.

[0032]These and other aspects of the present invention are explained and clarified with reference to the exemplary embodiments described hereafter.

Problems solved by technology

However, these Kirschner wires may be inadequate for fixation until final healing, so that subsequent positioning of bone plates needs to take place.

However, the Kirschner wire clamps known from prior art are difficult to handle, making it hard to carry out satisfactory preliminary fixation of a bone plate, comprise only limited functionality, or require significantly more time and space for their use.
