elastrator(redirected from elastrator ring)
an implement used for castration and tail docking by applying elastrator rings to animals. Closing the handles of this double-action, scissor-like instrument opens the jaws and dilates the rubber ring. This is slipped over the scrotum or tail and the handles released. The ring is now in place and the tool is withdrawn.
a specially constructed, thick and very strong rubber ring for use in an elastrator. Has sufficient strength to close off all the blood vessels to a part and cause it to slough.
