DEVICE FOR PERCUTANEOUS DILATIONAL TRACHEOTOMY

摘要

To be able to prevent a situation in which, in percutaneous dilational tracheotomy, the guide catheter already inserted into the trachea can break off, the present invention proposes a device for percutaneous dilational tracheotomy which has a puncture needle, a guide catheter and a guidewire, wherein the puncture needle has a ground tip at its distal end, wherein the maximum external diameter of the puncture needle is smaller than the minimum internal diameter of the guide catheter, and wherein 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, wherein the device according to the invention is in particular characterized in that 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.
