Abstract
Abstract A tracheotome for the mechanized performance of a tracheostomy. The inventive tracheotome, upon triggering, makes an incision through the skin, fascia and trachea of the patient. Then, after the incision has been made, a delayed-action plunger is activated and serves to bend a staple which maintains the opening in the trachea.
