Abstract
A tracheostomy dilator comprises a rod which is penetrated by an inner lumen. Both ends of the inner lumen are open, at the end facing the patient and at the end of the tracheostomy dilator facing away from the patient. The end facing the patient is provided with a thread. The tracheostomy dilator is used as screw dilator and can widen the tissue in one single dilation process such that a further tracheostomy cannula can be inserted into the trachea.
