Fergusson-type mouth gag with Ackland tooth plates, England,. Mouth gags are used to keep a patient’s mouth open during surgery. If anaesthetics are given through a tube placed down the windpipe (trachea), it is important that the patient does not bite down on the tube and stop the flow of anaesthetic. The gag may also have been used to keep the mouth open during surgery – for example when tonsils were being removed. Contributors: Science Museum, London. Work ID: fa3q53fn.
