Abstract

A disposable medical device is especially an articulation for the relative positioning of fixation bars or of pins of an external fixator, having at least one clamp to be introduced into the medical device, the clamp has an element that alters its appearance when being heated over a threshold temperature, thus giving optical or mechanical information that the device should not be used a second time.
