FIXATION CLAMP

摘要

A fixation clamp for use in an external fixation system for holding bone fragments adjacent to each other with the help of fixation elements has at least one clamping assembly having a pair of jaws with at least two different size grooves to accommodate a bone fixation element such as a pin or rod. An alternate clamping assembly has at least three grooves wherein at least two of the grooves have a different size adapted to accommodate a correspondingly sized bone fixation element such as a bone pin. The longitudinal axes of the grooves define a polygon. The jaw pairs can be rotated about a central longitudinal axis to present different size reception cavities towards the pins or rocks depending on their diameter.

1. A fixation clamp for use in an external fixation system for holding bone fragments adjacent to each other with the help of fixation elements, comprising
at least one clamping assembly, and a central locking shaft extending through the one or more clamping assemblies for blocking the position of the clamping assemblies in a defined angular position; wherein each clamping assembly comprises two jaws, wherein each jaw comprises three grooves, wherein the longitudinal axis of each groove is perpendicular to the locking shaft, wherein one groove of one jaw corresponds to one groove of the other jaw to form a groove to accommodate a bone fixation element, wherein the longitudinal axes of the grooves span a triangle, and wherein at least two grooves have a different size adapted to accommodate a correspondingly sized fixation element.
