This application relates to a cannula (78) comprising a bevelled cannula tip (80) at the distal end and a cannula holder (16) holding the cannula (78) at the proximal end, as well as a stylet unit (82), which can be displaced from a starting position to an end position in the cannula (78), wherein the cannula (78) is particularly intended to deposit at least one element (18, 20) in a body. According to the invention, in order to ensure simple and reliable protection of the cannula tip as well as a locking of the stylet unit in the end position, the distal end (84) of the stylet unit protrudes a distance (A) beyond the cannula tip (80) in the end position and the stylet unit (82) is fixed in the end position while simultaneously covering the bevelled cannula tip (80). |
