Zusammenfassung:	To be able to prevent a situation in which, in percutaneous dilational tracheostomy, the guide catheter already inserted into the trachea can kink, a device for percutaneous dilational tracheostomy is disclosed which has a puncture needle, a guide catheter and a guidewire. The puncture needle has a ground tip at its distal end. The maximum external diameter of the puncture needle is smaller than the minimum internal diameter of the guide catheter, and the puncture needle is insertable so far into the guide catheter that the ground tip of the puncture needle protrudes beyond the distal end of the guide catheter. The maximum diameter of the guidewire is smaller than the minimum internal diameter of the puncture needle, with the result that the guidewire can be guided through the puncture needle such that its end protrudes beyond the ground tip of the puncture needle.
