Bone regenerator
From Memory Alpha, the free Star Trek reference.
A bone regenerator is a medical device used for repairing shattered bones. Starfleet medkits typically hold bone regenerators.
After Benjamin Sisko had gotten the bones in his arm shattered, during the attack on the USS Honshu. When Sisko regained consciousness and saw his arm in a sling, Dukat, the man who had rescued Sisko during his escape from the Honshu, had found a bone regenerator in the medkit aboard their shuttlecraft, but claimed that "I'm not much of a doctor, so I just put on the cast." (DS9: "Waltz")
